First Patient Treated in Phase I/II Trial in Acute Myeloid and Acute Lymphoblastic Leukemia with Lu177-PentixaTher, Expanding the Evidence Base for Targeted Radiotherapy Approach

Berlin and Würzburg, Germany, November 21, 2024 – Pentixapharm Holding AG, a biopharmaceutical company developing innovative first-in-class radiopharmaceuticals, today announced that the first patient has been treated in a Phase I/II clinical trial evaluating the safety and efficacy of Lu177-PentixaTher, a novel radiopharmaceutical therapy, in adults for relapsed/refractory CXCR4 positive acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). The trial, funded by the French Ministry of Health and led by a renowned investigator team from the University Hospital in Nantes, represents a significant step toward expanding targeted radiotherapy options for hematologic malignancies.

The investor-initiated study, named PENTILULA (ClinicalTrials.gov ID: NCT06356922) is a multicenter, open-label trial in which up to 21 patients with relapsed/refractory AML or ALL will be enrolled over a period of 24 months, with a total study duration of 36 months. The primary objective is to determine the maximal tolerated dose (MTD) of Lu177-PentixaTher, and to examine key efficacy parameters such as overall response rate (ORR) and complete remission (CR) after infusion of the novel radiotherapeutic agent.

Following a peer-reviewed publication in January 2023 in the prestigious Journal of Nuclear Medicine highlighting promising clinical results in the treatment of patients suffering from T-cell lymphoma, further evidence continues to be built up about the potential of Pentixapharm’s lead candidate, PentixaTher, for the treatment of haemato-oncological diseases.

The study is significant for Pentixapharm insofar as the incidence of ALL and AML, and hence the medical need, is much higher than that for T-Cell lymphoma. The PENTILULA trial is the first trial that combines PentixaTher with Lutetium-177, a radioisotope widely and successfully used for the treatment of castration resistant prostate cancer or neuroendocrine tumors.

Acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) are aggressive and life-threatening blood cancers that affect thousands of people worldwide each year. AML is the most common type of acute leukemia in adults, with an incidence of approximately 20,000 new cases per year and low five-year survival rate of 31.9% in the United States [1]. ALL is the most common type of cancer in children, with a high incidence in adults as well. Current treatment options often involve intensive chemotherapy and stem cell transplantation, which can have severe side effects. Effective radiotherapies in other indications are currently reimbursed with more than 100,000 USD per patient.

“Although treatments for acute leukemia have advanced, many patients continue to have limited options and face poor outcomes. We believe PentixaTher holds significant potential to address these unmet needs, offering a valuable radiopharmaceutical theranostic approach tailored to the individual patients with hematologic malignancies.” explains Dr. Dirk Pleimes, Group CEO and CMO at Pentixapharm. “We are delighted that leading experts such as Professor Françoise Kraeber-Bodéré of the Nuclear Medicine Department and Professor Patrice Chevallier of the Hematology Department in Nantes have decided to initiate this study to evaluate this novel radiotherapeutic treatment option. We are committed to providing our full support, leveraging our therapeutic knowledge with PentixaTher and facilitating access to the compound to drive this important research forward."

Professor Françoise Kraeber-Bodéré is the Head of the department of Nuclear Medicine at the University Hospital in Nantes, France, and an expert of the Oncology committee of the French Society of Nuclear Medicine (SFMN) as well as of the Oncology and Therapy committee of the European Association of Nuclear Medicine. She is on the scientific board of the French Lymphoma research group LYSA and expert for PET imaging in lymphoma and myeloma. Professor Patrice Chevallier is a specialist in Hematology and member of the executive committee and scientific council of HéMA, an umbrella organization for hemato-oncological research in Western France.

Pentixapharm Releases Interim Report for the Third Quarter of 2024

Loss of Pentixapharm Holding AG for the reporting period: €49k
No revenue realized during the stub fiscal year through the end of Q3
Current liabilities of €487k, mainly from the purchase of Pentixapharm AG shares

Berlin and Würzburg, Germany, November 12, 2024 – Pentixapharm Holding AG (ISIN: DE000A40AEG0), listed in the Prime Standard of the Frankfurt Stock Exchange, today published its consolidated interim report for the stub fiscal year from March 18 to September 30, 2024. Since the spin-off from Eckert & Ziegler SE, through which Pentixapharm AG and Myelo Therapeutics GmbH will be integrated into the group financial statements, was entered into the commercial register on October 2, 2024, this consolidated report includes only the figures for Pentixapharm Holding AG and does not yet contain results for either company.

Pentixapharm Welcomes CMS Decision to Enhance Reimbursement for Diagnostic Radiopharmaceuticals

Berlin and Würzburg, Germany, November 4, 2024 – Pentixapharm, a biopharmaceutical company developing innovative first-in-class radiopharmaceuticals, welcomes the recent announcement by the U.S. Centers for Medicare & Medicaid Services (CMS) to implement separate payments for specialized diagnostic radiopharmaceuticals used in the hospital outpatient setting, extending beyond the transitional pass-through payment period. This significant policy shift could have a direct impact on future reimbursement streams for Pentixapharm’s Ga68-PentixaFor, a diagnostic radiopharmaceutical for which Pentixapharm intends to start a U.S. centric phase III clinical trial next year. The pivotal clinical trial could lead to a U.S. market authorization in primary aldosteronism (PA), one of the major causes of secondary hypertension, as early as 2028.

The CMS pass-through payment period is a temporary reimbursement mechanism under the Hospital Outpatient Prospective Payment System (OPPS). Lasting up to three years, this period provides additional payments for newly introduced medical devices, drugs, and biologicals, encouraging hospitals to adopt cutting-edge technologies by covering their costs beyond standard rates. However, under previous policies, after the pass-through period ended, products would typically revert to standard OPPS payment bundles. With this new policy announcement, CMS has changed this approach, allowing for separate payments beyond the pass-through period for qualifying high-cost diagnostics.

This decision by CMS is highly significant given the size and impact of the Medicare and Medicaid systems, which together insure more than 140 million Americans. As the primary healthcare payer for older adults and individuals with disabilities, CMS’s reimbursement policies shape access to medical innovations across the country. The new rule, effective in 2025, also has the potential to set a market precedent that may influence private insurers to follow CMS’s lead in reimbursing innovative diagnostic tools, further expanding the accessibility of these advanced diagnostics. By providing consistent reimbursement for diagnostic radiopharmaceuticals that exceed a per-day cost threshold of US$630, CMS encourages other insurers to consider similar reimbursement strategies.

The separate payment rule will most likely apply to Pentixapharm's lead diagnostic compound, Ga68-PentixaFor, following its anticipated approval and the expiration of its pass-through status. Ga68-PentixaFor is a novel tracer for positron emission tomography (PET) imaging used to detect aldosterone-hypersecreting adenomas in patients diagnosed with primary Aldosteronism (PA). With rising prevalence rates for PA, now exceeding 20% in some populations with resistant hypertension, the need for accessible and precise diagnostics is greater than ever.

About Pentixapharm

PentixaFor (Gallium (68Ga) boclatixafortide) is an innovative PET tracer that specifically targets the chemokine-4 receptor (CXCR4), with broad applications in oncological, cardiovascular, and inflammatory diseases. Particularly in hypertension, PentixaFor has the potential to significantly improve patient management by identifying the presence of hormone-secreting adenomas through non-invasive and broadly available PET/CT imaging.

Apart from PentixaFor, the clinical pipeline also encompasses PentixaTher, an Yttrium-90 or Lutetium-177 based therapeutic against non-Hodgkin lymphomas (NHL). Clinical studies for both compounds have already commenced in Europe, including a dose-finding study for PentixaTher and a Phase III registration study for PentixaFor in marginal zone lymphoma. Recently, the EMA granted PRIME status to PentixaFor in the indication PA.

Pentixapharm Holding AG: US National Cancer Institute Starts Advanced Clinical Trial with PentixaFor

Berlin and Würzburg, Germany, October 29, 2024 – The National Cancer Institute (NCI) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), two highly respected research organizations belonging to the US government's National Institutes of Health (NIH), have started a clinical trial involving 77 patients to see if Pentixapharm’s new radioactive tracer PentixaFor ([68Ga]Ga-PentixaFor) can make it easier to identify functional adrenal tumors through positron emission tomography (PET) scans.

The FDA-endorsed and US-located investigator-initiated phase II study, conducted by Dr. Liza Lindenberg and Prof. Dr. Peter Choyke (Clinical Trial number: NCT06246357) investigates the performance of PentixaFor in subtyping hormone-secreting adenomas in people suffering from primary aldosteronism (PA) or hypercortisolism (Cushing´s syndrome). The first patient was recently examined.

Primary aldosteronism is among the most common causes of secondary hypertension, a disorder affecting tens of millions of people in the United States alone. In some subtypes PA can be cured completely through a short surgical intervention, so finding a reliable tool for accurate subtyping is important and potentially beneficial to a large segment of the population. In contrast, Cushing's syndrome, also described as hypercortisolism, is a rare endocrine disorder designated as an orphan disease that is caused by chronic exposure of the body's tissues to excess levels of cortisol.

Pentixapharm itself is currently preparing a US-centric Phase III pivotal study to obtain marketing authorization for PentixaFor in PA. The work of the NCI/NIDDK will add to the global clinical evidence about the compound and make it easier to compile the necessary data.

“We are pleased that the NIH investigate the clinical value of PentixaFor at its own initiative and see this as a token of confidence in the potential of CXCR4 targeting imaging in unexplored indications expanding market opportunities for PET/CT diagnostics. In our opinion, PentixaFor has broad potential as a novel imaging modality for adrenal diseases and could be particularly helpful for individuals grappling with primary aldosteronism-induced resistant hypertension or Cushing’s disease,” stated Dr. Dirk Pleimes, Chief Medical Officer at Pentixapharm.

EMA Grants PRIME Status to Pentixapharm’s Lead Candidate PentixaFor

Disclosure of Insider Information according to Article 17 of Regulation (EU) No. 596/2014

Würzburg and Berlin, Germany, October 18, 2024 - The European Medicine Agency (EMA) has granted PRIME Status to Pentixapharm’s lead candidate Ga68-PentixaFor, thereby granting an early and proactive support for the development of the radiodiagnostic and the possibility of an accelerated approval. The benefits of PRIME status include an early appointment of CHMP or CAT rapporteurs, iterative scientific advice on development plans, introductory meeting on regulatory requirements, and potentially a total fee exemption for scientific advice. The status also confirms that PentixaFor has the potential to address, in primary aldosteronism (PA), an unmet medical need to a significant extent.

PentixaFor is a novel tracer for positron emission tomography (PET) imaging targeting the C-X-C receptor 4 (CXCR4). High expression of CXCR4 has been identified in aldosterone-producing tissue, which is responsible for the aldosterone over-secretion that causes PA. PentixaFor aims to be a non-invasive and accurate alternative to adrenal venous sampling (AVS), the current invasive and difficult Standard of Care procedure, offering the potential to transform diagnostic subtyping in PA.

PRIME is a status granted by the EMA for promising medicines that target an unmet medical need with the goal of optimizing these medicines’ development. The PRIME scheme is based on enhanced interaction and dialogue between EMA and Sponsor, to improve the development plans and speed up the evaluation, so that the medicines can earlier reach the patients. In particular, the PRIME scheme allows iterative scientific advice on the overall development plans and key issues, expedited follow-up scientific advice with shortened timelines, and potential accelerated assessment at the time of application for a marketing authorization. Since the start of the program in 2016, only 139 applications were granted, with Ga68-CXCR4 being the first radiodiagnostic.

Primary aldosteronism, also known as Conn’s syndrome, is an adrenal gland disorder and the most common cause of secondary hypertension. However, it remains difficult to diagnose and to effectively treat with current methods. Pentixapharm is currently preparing a Phase III pivotal study to obtain marketing authorization in PA that will start in 2025.

About Pentixapharm Holding AG

Pentixapharm Holding AG was founded in 2024 to incorporate all shares held by Eckert & Ziegler SE in Pentixapharm AG, based in Würzburg, following the spin-off resolved by the Annual General Meetings of Eckert & Ziegler SE and Pentixapharm Holding AG on June 26, 2024.

Pentixapharm Holding AG Sets Price Range for Planned IPO

Offering of up to 3.9 million new shares at a price range of EUR 4.70 to EUR 6.00 per share
IPO proceeds to secure financing for further development of promising product pipeline in the rapidly growing field of radioligand therapies
Subscription period for institutional and retail investors begins on September 24, 2024, and is expected to end on October 1, 2024
First trading day on the Prime Standard of the Frankfurt Stock Exchange anticipated on October 3, 2024
High free float of over 60% expected post-IPO

Berlin and Würzburg, Germany, September 23, 2024 – Pentixapharm Holding AG ("Pentixapharm"), a biopharmaceutical company focused on developing innovative first-in-class radiopharmaceuticals for the diagnosis and therapy ("theranostics") of blood cancer and other widespread indications not yet treated with radiopharmaceuticals, announces details of its planned initial public offering ("IPO") on the Prime Standard of the Frankfurt Stock Exchange. The German Federal Financial Supervisory Authority (BaFin) has today approved the prospectus for the public offering in Germany and the listing of Pentixapharm shares.

The IPO price range has been set at EUR 4.70 to EUR 6.00 per share. The final offer price will be determined based on a bookbuilding process at the end of the offering period, which begins on September 24, 2024, and is expected to end on October 1, 2024, at 12:00 p.m. CEST for retail investors and at 2:00 p.m. CEST for institutional investors.

The public offering comprises up to 3,900,000 registered shares. There is no over-allotment option (“greenshoe”). In addition to the offered shares, 50,000 nominal shares and 20,845,477 spin-off shares will be admitted to trading on the regulated market of the Frankfurt Stock Exchange (Prime Standard). The spin-off shares result from a capital increase in kind resolved by the extraordinary general meeting on June 26, 2024, consisting of all shares held by Eckert & Ziegler SE in Pentixapharm AG following the spin-off of Pentixapharm AG approved by Eckert & Ziegler SE's general meeting on the same day. In total, up to 24,795,477 registered shares of Pentixapharm Holding AG will be admitted to trading. All shares have a notional value of EUR 1.00 per share in the company's share capital and carry full dividend rights from March 25, 2024.

Proceeds from the Offering to Fund Further Development of the Product Pipeline

Assuming full placement of the shares, the IPO would result in a market capitalization of EUR 132.7 million at the midpoint of the bookbuilding range. The expected gross proceeds for Pentixapharm from the placement of new shares amount to between EUR 18.3 million and EUR 23.4 million, based on the bookbuilding range and the maximum number of 3.9 million offer shares. With an additional convertible bond of up to EUR 18.5 million subscribed by the listed Eckert & Ziegler SE, Pentixapharm would have over EUR 39 million in additional financial resources at the midpoint of the bookbuilding range to implement the first phase of its growth strategy.

The proceeds from the IPO are primarily intended for the further development of the company’s product pipeline. The growth strategy in the coming years is focused on the clinical development and approval of main candidates, Ga68-PentixaFor and Y90-PentixaTher, as well as on strategic partnerships and potential acquisitions in the field of radiopharmaceuticals. The IPO is thus a milestone on the planned path toward commercialization of well-validated programs. Lead candidate PentixaFor is already in Phase III clinical development in Europe.

Dr. Hakim Bouterfa, CEO of Pentixapharm Holding AG, commented: "We are now in the home stretch with our IPO plans and are pleased with the positive feedback from investors. Our goal is to make the stock attractive to investors who join early and to minimize the dilution of Eckert & Ziegler SE shareholders who become Pentixapharm shareholders as a result of the spin-off. Therefore, only a limited number of shares are being offered in the IPO. We are convinced of a positive development of Pentixapharm and aim to achieve further milestones in the coming months."

Dr. Andreas Eckert, Chairman of the Supervisory Board of Pentixapharm Holding AG, stated: "Pentixapharm has an attractive product pipeline and is gaining access to capital market investors through the IPO. As previously announced, as part of the spin-off of Pentixapharm from Eckert & Ziegler SE, Eckert Wagniskapital und Frühphasenfinanzierung GmbH is also participating in the IPO, underscoring its confidence in Pentixapharm. For future investments, several options are available, including further capital measures or other financing possibilities such as collaborations with established pharmaceutical companies. The current valuations of companies in the field of radiopharmaceuticals with programs in clinical trials in the US underscore the potential that investors see in this field."

IPO Targeted at Both Institutional and Retail Investors Interested in Pentixapharm's Innovative Growth Model

The shares will be offered as part of a public offering in Germany and an international private placement. The offering is aimed at both institutional and retail investors. Retail investors in Germany can place purchase orders in the public offering one day after the start of the offer period, i.e., from September 25, 2024, exclusively via the DirectPlace© subscription functionality of the Frankfurt Stock Exchange or through their custodian bank. Qualified investors can place purchase orders directly with BankM AG, acting as sole global coordinator and sole bookrunner, during the offer period. The free float after the IPO is expected to be over 60%. The main shareholder of Pentixapharm is Eckert Wagniskapital und Frühphasenfinanzierung GmbH, which will hold 31.57% of the share capital after the completion of the spin-off.

Admission to trading is expected on October 2, 2024. On October 3, 2024, the listing of the existing shares and the spin-off shares of Pentixapharm Holding AG under the ticker symbol "PTP" and the International Securities Identification Number (ISIN) DE000A40AEG0 is scheduled to take place on the regulated market (Prime Standard) of the Frankfurt Stock Exchange. The offer shares are expected to be traded from October 10, 2024, following the registration of the capital increase in the commercial register and the admission decision by the Deutsche Börse AG.

Pentixapharm Holding AG, a Subsidiary of Eckert & Ziegler SE, Plans IPO on the Prime Standard of the Frankfurt Stock Exchange

ADVERTISEMENT - NOT FOR DISTRIBUTION OR ANNOUNCEMENT, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES OF AMERICA, AUSTRALIA, CANADA, JAPAN, SOUTH AFRICA OR ANY OTHER JURISDICTION IN WHICH THE DISTRIBUTION OR ANNOUNCEMENT WOULD BE UNLAWFUL

Business model focused on innovative radiopharmaceuticals for the diagnosis and therapy (theranostics) of various indications
Institutional environment characterized by high market growth and intense M&A activity
IPO as a strategic step to secure short- and long-term financing
Lead candidate PentixaFor already in Phase III
Commercial rights to over 20 investigator-initiated studies (IIS) for accelerated pipeline development

Berlin and Würzburg, Germany, September 12, 2024 – Pentixapharm Holding AG (“Pentixapharm”) is planning a public offering of new shares as part of its spin-off from Eckert & Ziegler SE, with the goal of listing on the Regulated Market (Prime Standard) of the Frankfurt Stock Exchange in the fourth quarter of 2024. The offering will primarily target institutional investors but will also be open to retail investors.

Pentixapharm focuses on the development of radiopharmaceuticals for various therapeutic areas. For some of the indications, Pentixapharm’s development candidates would represent first-in-class radiopharmaceuticals. This includes radiotherapeutics against multiple forms of blood cancer. Pentixapharm here aims to confirm and replicate, in controlled clinical trials, the promising results of a first small study with its lead candidate PentixaTher in patients with hard-to-treat T-cell lymphomas that had previously not responded to standard therapies reported in 2022 by the University of Würzburg.

In addition, Pentixapharm plans to initiate a Phase III registration trial in the United States for its most advanced development candidate, PentixaFor, in the indication of primary aldosteronism (PA). In a recent pre-submission (Type-C) meeting, the U.S. Food and Drug Administration (FDA) indicated that key pre-conditions for a phase III trial have been met. PA, a significant cause of hypertension, remains difficult to diagnose and treat effectively with current methods.

The medical significance and economic potential of radiopharmaceutical therapies are underscored by several international M&A transactions in the last 12 months, totaling around USD 8 billion. Through its planned IPO, Pentixapharm aims to strategically position itself in this growing market, expand its financial resources for continued pipeline development in the short term, and secure long-term capital access. The IPO will be led by BankM AG, acting as Bookrunner and Lead Manager.

Dr. Andreas Eckert, Chairman of the Supervisory Board of Pentixapharm Holding AG: "We are pursuing a highly promising, differentiated, and well-validated approach with Pentixapharm in the rapidly growing international radiopharmaceutical market. With our extensive experience and network, we are in an excellent position to quickly deliver a broad pipeline of diagnostic and therapeutic solutions, not only for cancer but also for other indications. The planned IPO is a significant milestone on our path toward the commercial use of our diagnostic and therapeutic programs."

Clear focus on well-researched targets, lead program in Phase III clinical development

At the core of Pentixapharm's operations are the exclusive global rights to a patent family developed by the University of Munich, centered around radioisotope-labeled ligands targeting the cell membrane receptor CXCR4. This protein plays a critical role in tumor growth, metastatic spread, and the development of inflammatory processes.

Dr. Hakim Bouterfa, CEO of Pentixapharm Holding AG: "The theranostic approach allows us to detect, treat, and precisely monitor disease progression and response to therapy. The specific binding of the ligand to the pathological surface structure of the target cell is identical for both diagnosis and therapy, enabling a targeted treatment according to the principle of 'find, fight, and follow'. The choice of radioisotope then determines the outcome: high-energy isotopes are used to destroy targeted cells, while lower-energy isotopes are employed for imaging purposes."

Pentixapharm’s clinical pipeline encompasses PentixaTher, an Yttrium-90 based therapeutic against non-Hodgkin lymphomas (NHL), and PentixaFor, a Gallium-68-based companion diagnostic. Clinical studies for both compounds have already commenced in Europe, including a dose-finding study for PentixaTher and a Phase III registration study for PentixaFor in marginal zone lymphoma. Additionally, PentixaFor is being developed as a diagnostic tool for primary aldosteronism (PA), a significant cause of hypertension. Pentixapharm is currently preparing a US-centric Phase III registration study with PentixaFor in PA that is expected to start in 2025.

Unique network and extensive data pool for accelerated pipeline development

Leveraging the longstanding experience of Eckert & Ziegler, one of the world's largest providers of isotope technology for medical, scientific, and industrial applications, Pentixapharm, as a former subsidiary, benefits from outstanding expertise and a broad network in the field of radiopharmaceuticals. Currently, Pentixapharm can access data from over 20 academic partners who have investigated the potential of the CXCR4 cell membrane receptor in developing radiopharmaceuticals through investigator-initiated studies (IIS).

The spin-off of Pentixapharm, approved by Eckert & Ziegler SE's Annual General Meeting on June 26, 2024, is based on the distinct business focuses of the two companies. While Eckert & Ziegler's core business revolves around the production and distribution of radioisotopes, Pentixapharm is dedicated to the development and approval of new radiopharmaceuticals. The planned IPO enables Pentixapharm to target investors specifically interested in the company's innovative and forward-looking pipeline. As an independent company, Pentixapharm can now operate more flexibly to advance its research and development projects.

It is intended to list Pentixapharm Holding AG in the Regulated Market (Prime Standard) of the Frankfurt Stock Exchange.

Pentixapharm AG is a clinical-stage radiopharmaceutical development company founded in 2019.

Pentixapharm AG Receives Orphan Drug Designation for its Radiodiagnostic Tracer PentixaFor in Marginal Zone Lymphoma by the European Medicines Agency

Berlin and Würzburg, Germany, August 26, 2024 - Pentixapharm Holding AG, the future holding company of Pentixapharm AG, a clinical-stage biotech company discovering and developing novel targeted radiopharmaceuticals, today announced that the European Medicines Agency (EMA) and the European Commission (EC) have granted an Orphan Drug Designation for the diagnostic tracer PentixaFor, also known as Gallium (68Ga) boclatixafortide, for the diagnosis and staging of Marginal Zone Lymphoma.

Marginal Zone Lymphoma (MZL) is a type of non-Hodgkin’s Lymphoma (NHL) and has been recognized by the EMA as a chronically debilitating and life-threatening condition. Pentixapharm currently sponsors a European Phase III clinical trial to assess the performance of PentixaFor for the imaging and staging in patients with confirmed MZL.

PentixaFor is a novel tracer for positron emission tomography (PET) imaging targeting the C-X-C receptor 4 (CXCR4), which is overexpressed on MZL cells. Preclinical and clinical studies indicate that PentixaFor has a high sensitivity and specificity for the diagnosis and staging of MZL, with potentially better outcomes than the currently used [18F]FDG. An improved staging of the malignant disease is key to a more successful treatment.

The European Orphan Drug Program aims to support companies that develop medicinal products for diseases which affect no more than 5 in 10,000 people in the EU. The benefits of an Orphan Drug Designation include the possibility of seeking EMA protocol advice for PentixaFor development in MZL, regulatory fee reductions and waivers, and the access to the European centralized marketing authorization application. Additionally, upon market approval, PentixaFor could benefit from 10 years of market exclusivity within the EU for the diagnosis and staging of MZL.

Pentixapharm Acquires Target Discovery Business of Glycotope

Würzburg and Berlin, Germany, July 3rd, 2024 – Pentixapharm AG, a clinical-stage biotech company discovering and developing novel targeted radiopharmaceuticals against a range of malignancies, has announced the execution of an agreement, effective July 1st, to acquire the target discovery business of Berlin-based Glycotope GmbH.

The deal encompasses a portfolio of preclinical antibodies against multiple oncology targets that can be developed into radiopharmaceuticals. It also includes Glycotope’s laboratories, cell banks, tumor target data base, and the equipment needed to exploit the discovery platform, along with a range of patents, licenses, and other tangible assets. In total, Pentixapharm will be able to add an integrated team of 40 seasoned executives, R&D specialists, and administrators to its staff.

“The acquisition will broaden Pentixapharm’s Intellectual Property portfolio beyond the one built around the CXCR4 receptor. This will immediately double the development pipeline and significantly expand the associated business and clinical development opportunities,” explained Hakim Bouterfa, CEO of Pentixapharm AG. “Glycotope’s pipeline comprises several candidates that can be used immediately for proof-of-concept studies as next generation radiopharmaceuticals. We look forward to maximizing the synergy of Pentixapharm’s know-how and Glycotope’s target discovery for the benefit of patients in both diagnostics and therapeutic applications.”

“The transaction provides Pentixapharm not just with a chance to build a clinical pipeline beyond the company’s current CXCR4-ligand based programs, but also substantially strengthens its administrative and managerial capacities,” noted Andreas Eckert, Chairman of the Supervisory Board of both Pentixapharm and mother company Eckert & Ziegler SE (EZAG). “It adds a critical number of talents to the planned secession of Pentixapharm to Frankfurt Stock Exchange, thereby facilitating a seamless separation from EZAG. The offices and laboratories included in the deal are large enough to allow a consolidation of all Berlin-based activities into one location.”

The transaction will also affect the composition of the Pentixapharm Management Board once the company becomes listed on the Frankfurt Stock Exchange. Hakim Bouterfa, current CEO of Pentixapharm, is designated to move to the Company’s Supervisory Board. He will be succeeded by Dirk Pleimes, currently Pentixapharm’s Chief Medical Officer. Patrik Kehler, former Chief Scientific Officer (CSO) of Glycotope, will assume the CSO position at Pentixapharm, while Glycotope’s former CEO, Henner Kollenberg, will take over the responsibility for administrative and business development issues as Chief Business Officer.

Patrik Kehler, newly appointed Chief Scientific Officer of Pentixapharm, explained: “The target discovery unit’s development activities focus on tumor-associated carbohydrate structures, so-called GlycoTargets. Their major advantage is the reduced normal tissue binding compared to conventional antibodies. Based on their superior tumor-specificity, they are suitable for development in an array of different modes of action. In the radiopharmaceuticals field, they have the potential to close the treatment gap that exists for the majority of solid tumors.”

About the Glycotope Target Discovery Unit

The target discovery unit utilizes a proprietary technology platform to develop uniquely tumor-specific monoclonal antibodies or fragments thereof. They target specific tumor-associated carbohydrate structures or protein/carbohydrate combined glycoepitopes (GlycoTargets). The unit has to date discovered in excess of 200 GlycoTargets (www.glycotope.com). Many of these have been outlicensed to major pharmaceutical companies around the world, where they are currently in pre-clinical and clinical development.

Eckert & Ziegler Subsidiary Pentixapharm Receives Encouraging FDA Feedback to Initiate Phase III Trial with PentixaFor as Radiopharmaceutical Diagnostic in Primary Aldosteronism

Würzburg, Germany, June 25th, 2024 – Pentixapharm AG, a radiopharmaceutical development company wholly owned by Eckert & Ziegler SE, today announced that it has received encouraging feedback from the U.S. Food and Drug Administration (FDA) following a recent Type C meeting with the Agency to directly proceed into a pivotal phase III registration study with its radiopharmaceutical diagnostic Ga68-PentixaFor in Primary Aldosteronism (PA). PA is an adrenal gland disorder also known as Conn’s syndrome and the most frequent cause of secondary hypertension (high blood pressure).

While the FDA minutes from the Type C meeting do not constitute a formal approval of a particular development plan, they indicate that the clinical data compiled by various academic groups independently from Pentixapharm might serve as confirmatory evidence, relieving the Company of the requirement to conduct a second well-controlled clinical investigation. The minutes also confirm that Ga68-PentixaFor addresses an unmet medical need for a serious condition and therefore meets two essential criteria for fast track and breakthrough designation, which Pentixapharm can request with its Investigational New Drug (IND) submission to initiate the phase III trial.

Ga68-PentixaFor is a novel tracer used in the positron emission tomography (PET) imaging of aldosterone-hypersecreting adenomas in patients diagnosed with PA. The estimated prevalence of this disease has increased considerably over the years, exceeding 20% in some populations of resistant hypertension [1]. The disorder is characterized by either a unilateral aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia (BAH). The current gold standard for differentiating these conditions is adrenal venous sampling (AVS), a complex and invasive procedure. The vast majority of patients with unilateral PA who undergo adrenalectomy after successful AVS experience complete biochemical normalization [2]. However, there is a risk of misdiagnosing a bilateral case, in which a patient would not benefit from the removal of the gland.

Dr. Dirk Pleimes, Chief Scientific & Medical Officer at Pentixapharm AG, commented: “The FDA feedback represents a major milestone for our Company in the development of our lead diagnostic. We aim to evaluate Ga68-PentixaFor as a first-in-class, non-invasive and accurate alternative to adrenal venous sampling, offering the potential to transform diagnostic subtyping in Primary Aldosteronism and improve patient outcomes. This discussion with US regulatory authorities provided important feedback, enabling us to proceed to a US-centric registrational Phase III trial to support global authorization applications.”

First CNS Lymphoma Patient Dosed in Phase I/II PTT101 Study with Yttrium-90 Anditixafortide (PentixaTher)

(Only Available in English)

Berlin and Würzburg, Germany, November 22nd, 2023 - Pentixapharm AG, a developer of innovative radiopharmaceuticals owned by Eckert & Ziegler Strahlen- und Medizintechnik AG (ISIN DE0005659700) today has announced that a first patient has been treated in a dose-finding clinical phase I/II study with Yttrium (90Y) anditixafortide (PentixaTher) at the University Hospital in Essen, Germany.

This study, PTT101 (ClinicalTrials.Gov ID: NCT06132737), is a prospective, open-label dose-escalation, multicenter study to evaluate the safety, tolerability, biodistribution and efficacy of PentixaTher in patients with CNS lymphoma (cancer affecting the central nervous systems). PentixaTher is targeting the CXCR-4 cytokine receptor which is widely expressed in different cancer indications.

Before treatment, patients will be screened with Gallium-68 (68Ga)-based PentixaFor to confirm the presence of the CXCR-4 receptors. If the PET scan turns out to be positive, PentixaTher will be given in various doses to different dose group (in total 9 to 15 patients). The enrollment is planned to last 12 months.

“Previous studies have shown that up to 90% of CNS lymphoma patients overexpress the CXCR4 receptor. We therefore hope that the clinical results in CNS lymphomas with Yttrium (90Y) anditixafortide PentixaTher will show similar outstanding effects on tumor growth as we have observed it in other indications like T-cell lymphomas or Multiple Myelomas” commented Dr. Hakim Bouterfa, Chief Medical Officer at Eckert & Ziegler, and Member of the Board at Pentixapharm AG.

Lausanne University Hospital Investigates Use of PENTIXAFOR in Cardio-Vascular Setting

Phase II with PentixaFor

Würzburg / Berlin (Germany), February 1st, 2023

The Lausanne University Hospital (CHUV) has reported the initial dosing of a patient in a phase II clinical study investigating the sensitivity of PENTIXAFOR (Boclatixafotide) in a cardiovascular and inflammatory setting. It is the first time that Eckert & Ziegler’s proprietary CXCR4-compound is used in an advanced clinical test in a non-cancer indication, opening the way for a broader use of PENTIXAFOR outside of oncology.

The Gallium-68 based radio-diagnostic PENTIXAFOR promises to significantly improve the sensitivity in the detection of acute myocardial inflammation, which may allow for future early clinical management of patients with myocarditis, avoiding the progression to more severe stages.

To investigate the potential of PENTIXAFOR the CHUV will recruit, on its own account, up to 60 patients in a so-called investigator initiated study (ISS). Eckert & Ziegler, owner of the rights to the CXCR4 targeted tracer used in this study, supports the CHUV team under Professor John Prior and Professor Niklaus Schaefer by providing the compound. Also, part of the CHUV team is Professor Margret Schottelius, Head of the Translational Radiopharmaceutical Sciences lab at CHUV/Agora, who was involved in the preclinical development and clinical translation of PENTIXAFOR and Dr Judith Delage, Head of the Radiopharmacy Unit, in charge, together with her team, of the clinical transfer and of the GMP internal production.

Acute myocardial inflammation is a heterogenic inflammatory disease of the heart muscle involving different clinical pathologies and outcome. The CHUV study focuses on the three entities acute cellular cardiac allograft rejection, cardiac sarcoidosis and the immune checkpoint inhibitor induced myocarditis, as non-invasive diagnosis remains challenging for these life-threatening conditions with current standards.

“Including cardiovascular indications in our prognostic development program in addition to oncology demonstrates the exciting potential of PENTIXAFOR,” comments Dr Jens Kaufmann, co-founder and general manager of Pentixapharm. “We are delighted to collaborate with an excellent centre such as the CHUV in this field, led by Dr Christel Kamani as principal investigator.”

Dr Kamani is triple-certified in cardiology (2017), internal medicine (2018) and in nuclear medicine (2022). Dr Kamani has learned all techniques of multimodality cardiovascular imaging. His research interest focuses on non-invasive multimodality tools for the detection of cardiovascular disease.

PENTIXAFOR is being developed by Eckert & Ziegler’s subsidiary Pentixapharm GmbH primarily as a superiorly sensitive diagnostic for rare blood cancers, among them myelomas, lymphoma and leukaemia.
