LIXTE Biotechnology Announces a Supported Collaborative Trial to Study LIXTE’s First-in-Class PP2A Inhibitor, LB-100, Plus GSK’s Immunotherapy, Dostarlimab, in Clear-Cell Ovarian Cancer

On September 20, 2023 LIXTE Biotechnology reported a Phase 1b collaborative clinical trial to assess whether adding Lixte’s LB-100 to GSK’s programmed death receptor-1 (PD-1)-blocking monoclonal antibody, dostarlimab, may enhance the effectiveness of immunotherapy in the treatment of ovarian clear cell carcinoma (OCCC) (Press release, Lixte Biotechnology, SEP 20, 2023, View Source [SID1234637965]). The clinical trial is sponsored by The University of Texas – MD Anderson Cancer Center and will be conducted at MD Anderson and will also be open at Northwestern University’s Robert H. Lurie Comprehensive Cancer Center. LIXTE will provide LB-100; GSK will provide dostarlimab and financial support for the clinical trial.

The clinical trial is based on the observation of longer survival of patients with OCCC treated with immunotherapy whose cancer cells have an acquired gene mutation resulting in a reduction in PP2A. This finding was reported by the lead clinical investigators of this new trial1: Amir Jazaeri MD, Professor of Gynecologic Oncology at MD Anderson, and Emily Hinchcliff, MD, MPH, Assistant Professor of Obstetrics and Gynecology at Northwestern University Feinberg School of Medicine. The observation by Drs. Jazaeri and Hinchcliff, that a genetically acquired reduction in PP2A enhances sensitivity to immunotherapy, raises the possibility that reducing PP2A pharmacologically with LB-100 will enhance the anti-tumor effect of the PD-1 blocking monoclonal antibody dostarlimab in patients with OCCC lacking the genetic reduction in PP2A.

John S. Kovach, M.D., LIXTE’s founder and Chief Executive Officer, said, "Preclinical data supports the idea that LB-100 enhances the efficacy of PD-1 therapy.1 Clinical data also supports this idea, in that patients with ovarian clear cell carcinoma with dysfunctional PP2A due to somatic mutations in PPP2R1A have shown dramatically longer survival after treatment with immune checkpoint blockers."

Dr. Hinchcliff, said, "OCCC is a comparatively chemotherapy resistant disease and therefore has very limited options for treatment. This clinical trial is an exciting alternative approach that leverages the potential synergy between these two agents and is aiming to improve the impact immunotherapy may have for these patients."

RefleXion Acquires Global Rights to Radiopharmaceutical Molecule from 3B
Pharmaceuticals to Treat High Unmet Need Cancers Including Brain, Pancreatic and
Liver

On September 20, 2023 RefleXion Medical, Inc., a therapeutic oncology company and 3B Pharmaceuticals (3BP) GmbH, a biotechnology company developing targeted radiopharmaceutical drugs and diagnostics for cancer detection and treatment, reported an exclusive licensing agreement for RefleXion to develop and commercialize a specific 3BP molecule to direct its SCINTIX biology-guided radiotherapy (Press release, 3B Pharmaceuticals, SEP 20, 2023, View Source [SID1234635302]). This molecule may significantly expand the patient population eligible for SCINTIX therapy to patients with solid tumor cancers of any stage in a manner that may improve both outcomes and procedural workflow.

The proprietary molecule, termed RXM-4768, targets fibroblast activation protein (FAP) found in nearly all solid tumor types. Using its technology platform, 3BP has discovered and characterized a large portfolio of FAP-targeting molecules as potential diagnostic and therapeutic radiopharmaceuticals. Together the companies selected one molecule optimized for utility with RefleXion’s SCINTIX radiotherapy that expands the role of FAP-targeting molecules to now include directing external-beam radiotherapy delivery in real time.

"This molecule has the potential to light up most solid tumor types in the body, thus demonstrating the power of radiopharmaceuticals by enabling SCINTIX therapy to reach patients with metastatic cancers that currently have dismal outcomes," said Thorsten Melcher, Ph.D., chief business officer at RefleXion.

"Our partnership with 3BP is as unprecedented in the external-beam radiotherapy industry as our SCINTIX therapy is for cancer treatment. We are excited, in collaboration with 3BP and others, to advance this molecule through clinical testing to commercialization." Overcoming the hurdles of targeting and motion management, especially for multiple tumors, is the core challenge in external beam radiotherapy. SCINTIX therapy, delivered by the RefleXion X1, uses emissions from cancer cells created by injecting the patient with a radiopharmaceutical to deliver a radiation dose that continuously and autonomously targets the cancer itself.

"We designed RXM-4768 with the unique requirements for SCINTIX therapy in mind, and our preclinical data demonstrated its potential as an effective biology guide for potentially most solid tumor cancer types," said Dr. Ulrich Reineke, founder & managing director of 3B Pharmaceuticals. "We look forward to working with RefleXion and their collaborator network to bring this project to fruition."

RXM-4768 was previously known as 3BP-4768 and is part of the rights retained by 3BP under the Global Exclusive Licensing Agreement for 3BP’s FAP-targeting peptide technology with Novartis Innovative Therapies AG. Under the terms of the agreement, RefleXion has worldwide, exclusive and sublicensable rights to continue development and subsequent commercialization of RXM-4768 for use with SCINTIX biology-guided radiotherapy. Terms of the transaction also include upfront and annual license payments to 3BP. Upon achievement of certain regulatory and commercial milestones, additional payments and commercial royalties would be due to 3BP. Further terms of the agreement were not disclosed.

RefleXion recently announced completion of the world’s first SCINTIX treatment in a patient with a recurrent lung tumor at Stanford Medicine Cancer Center. This milestone ushers in a new era of autonomous radiotherapy where the biology of the tumor directs where to deliver the radiation dose.
