Cybrexa Therapeutics Announces CBX-12 as Lead Development Program

New Haven, Conn., January 9, 2020 – Cybrexa Therapeutics, an oncology-focused biotechnology company developing a new class of therapeutics through its alphalex™ tumor targeting platform, today announced CBX-12 (alphalexTM-exatecan) as the new lead development program. CBX-12 is an alphalexTM conjugate that includes the highly potent topoisomerase I inhibitor exatecan.

CBX-12 has demonstrated strong efficacy and a solid safety profile in preclinical studies.  CBX-12 leverages the same class of payload used in the antibody-drug conjugate (ADC) ENHERTU® (fam-trastuzumab deruxtecan-nxki), which was recently approved by the U.S. Food and Drug Administration under Accelerated Approval in unresectable or metastatic HER2-positive breast cancer. Like ENHERTU®, CBX-12 delivers a highly potent topoisomerase I payload, but CBX-12 targets tumors without the need for a specific antigen and therefore has the potential to address a much broader patient population. CBX-12 has potential synergy with PD-1 inhibitors and other immuno-oncology drugs. Cybrexa plans to publish preclinical data for CBX-12 in the first half of 2020 and to advance the program into the clinic in 2021.

Per Hellsund, President and CEO of Cybrexa said, “CBX-12 has tremendous potential to change the treatment paradigm in multiple solid tumors, which remain hard to treat.  We are committed to moving this program rapidly into the clinic, and ultimately benefit as many patients as possible.  We look forward to reporting on CBX-12’s progress at upcoming high-profile medical conferences in 2020.”

Chief Scientific Officer Vishwas Paralkar, PhD, added, “The CBX-12 program has shown outstanding results in preclinical studies and showcases the potential and opportunity for the alphalexTM platform. We continue to make good progress with our other programs in the preclinical pipeline and look forward to advancing those candidates as we work to provide treatments to as many patients as possible.”

Cybrexa Therapeutics Announces Expansion of its Anticancer Pipeline

 

New Haven, Conn., December 9, 2019 – Cybrexa Therapeutics, a biotechnology company developing a new class of cancer therapeutics through its alphalex™ tumor targeting platform, today announced that the Company is expanding the application of its proprietary alphalex™ platform to include toxin conjugates and additional next generation synthetic lethality targets.

Two of Cybrexa’s new preclinical pipeline programs include CBX-12 (alphalexTM-exatecan) and CBX-13 (alphalexTM-DM4).  Both exatecan and DM4 are highly toxic to cells and require targeted delivery to be used as cancer therapies, making them prime opportunities for the alphalexTM platform.  Both programs are expected to have efficacy across a variety of solid tumors.  Preclinical work is ongoing, with publication of initial data expected by mid-2020.

Per Hellsund, President and CEO of Cybrexa said, “We are excited to broaden the application of our alphalexTM technology platform to expand our pipeline. We have made rapid progress with our new programs and believe these agents could be transformative both in patient populations where few treatment options or remaining unmet needs exist. We look forward to continuing to explore new applications of alphalexTM to bring benefits to patients.”

Scientific Co-founder Peter Glazer, MD, PhD, commented on CBX-12, “Our early preclinical data shows very impressive efficacy in mouse tumor models with essentially no toxicity, quite unlike the situation that you see with the free molecule [exatecan].  We believe that this will provide the needed therapeutic index to apply the Cybrexa technology with exatecan to a variety of human solid tumors.”

About Poly (ADP-ribosome) polymerase (PARP) inhibitors in Combination with Chemotherapy

Poly (ADP-ribosome) polymerase (PARP) inhibitors have demonstrated clear efficacy as monotherapies in the clinic against metastatic solid tumors in cancers with homologous recombination deficiency (HRD). PARP inhibitors have showed only limited activity against non-HRD cancers. Combination therapy with DNA-damaging chemotherapy agents has the potential to greatly enhance anti-tumor activity in non-HRD cancers, but combining PARP inhibitors with chemotherapy in clinical studies has been challenging largely due to the accompanying toxicity.

Cybrexa Therapeutics’ Preclinical Data Demonstrate its alphalex™ Platform Enables Tumor Targeting of Multiple PARP Inhibitors, Effectively Inducing Significant Tumor Cell Killing When Combined with Chemotherapy

Cybrexa Therapeutics’ Preclinical Data Demonstrate its alphalex™ Platform Enables Tumor Targeting of Multiple PARP Inhibitors, Effectively Inducing Significant Tumor Cell Killing When Combined with Chemotherapy

Results support the potential of alphalex™ technology with diverse range of anticancer agents

Targets HRD-negative cancers, while avoiding significant bone marrow toxicity typically induced when PARP inhibitors are combined with chemotherapy

New Haven, Conn., May 15, 2019 – Cybrexa Therapeutics, a biotechnology company developing a new class of cancer therapeutics through its alphalex™ tumor targeting platform, today announced preclinical data supporting the potential of its proprietary alphalex™ technology platform. Results from multiple preclinical studies demonstrate that alphalex™ successfully enables the combination of a diverse range of structurally unique PARP inhibitors with DNA damaging chemotherapies in doses that effectively induce significant tumor cell killing, representing a new approach to target homologous recombination deficiency (HRD)-negative cancers without causing significant bone marrow toxicity.

The studies showed that each of the alphalex™-PARP inhibitor conjugated molecules was successfully delivered to tumor cells while sparing other tissues. Researchers observed significant reductions in PARylation activity and strong synergy with DNA damaging agents in vitro. Researchers then demonstrated that alphalex™-PARP inhibitor conjugates in combination with both temozolomide and irinotecan induced significant tumor cell killing in HRD-negative tumors in vivo. Importantly, they found that the alphalex™ tumor-targeting approach significantly reduced normal tissue toxicity, with almost complete sparing of the bone marrow relative to temozolomide alone.

“Cybrexa’s unique alphalex™ platform enables multiple PARP inhibitor combinations with clinically-relevant chemotherapies, providing a new way to target HRD-negative cancers without significant bone marrow toxicity,” said Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa. “Based on these successful proof-of-concept data, we are now performing IND-enabling studies for our lead program, CBX-11 (alphalex-rucaparib), and plan to initiate our first Phase I clinical trial in the first quarter of 2020 in solid tumors independent of HRD status. This is the first of several programs we plan to bring to the clinic that have the ability to leverage the efficacy of known potent anticancer agents without inducing associated toxicities.”

The data were published in an online only abstract, titled “Unlocking PARP inhibitor efficacy for HRD-negative cancers using the alphalex™ tumor targeting platform,” accepted by the American Society for Clinical Oncology (ASCO) Annual Meeting 2019.

Cybrexa Therapeutics Unveils Rucaparib as FDA- and EMA-Approved PARP Inhibitor in Lead Candidate CBX-11, Which Demonstrates Synergistic Efficacy with Chemotherapy Without Compounded Toxicity

Cybrexa Therapeutics Unveils Rucaparib as FDA- and EMA-Approved PARP Inhibitor in Lead Candidate CBX-11, Which Demonstrates Synergistic Efficacy with Chemotherapy Without Compounded Toxicity

Tumor-selective CBX-11 allows full dose co-administration with chemotherapy, enabling synergistic efficacy in HRD negative tumors  

Poster presentation today during AACR Annual Meeting 2019

New Haven, Conn., April 2, 2019 – Cybrexa Therapeutics, a biotechnology company developing a new class of cancer therapeutics through its alphalex™ tumor targeting platform, today announced that the FDA- and EMA-approved poly ADP-ribose polymerase (PARP) inhibitor rucaparib (marketed as Rubraca®) is conjugated in lead candidate CBX-11 (alphalex™-rucaparib). The first set of preclinical data supporting CBX-11 demonstrate that Cybrexa’s proprietary alphalex™ platform can enable full dose administration with DNA damaging chemotherapy, creating synergistic efficacy in destroying solid tumors independent of homologous recombination deficiency (HRD) status. In particular, CBX-11 selectively delivers rucaparib to tumor tissue, avoiding the bone marrow toxicity that has prevented optimal dosing of DNA damaging chemotherapy in combination with PARP inhibitors.

These data were exhibited today in a poster presentation by Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa, during the American Association for Cancer Research (AACR) Annual Meeting 2019.

“These mark the first results demonstrating that combination of the potent PARP inhibitor rucaparib and chemotherapy is able to effectively kill cancer cells independent of HRD status and without the extreme bone marrow toxicity historically observed in this combination, which previously resulted in significant dose reduction and therefore efficacy reduction,” said Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa. “The synergistic efficacy allowing full dose administration of both rucaparib and chemotherapy is a direct result of our alphalex™ technology platform that selectively targets tumor cells to overcome this barrier for combination therapies.”

In the study, tumor targeting of rucaparib was achieved using the alphalex™ platform, which allows small molecule anti-cancer agents to penetrate cell membranes only at the low pH associated with the tumor microenvironment. These data demonstrate that the alphalex™ conjugate inserts only across cancer cell membranes to deliver its cargo directly into the cancer cell.  The safety and efficacy of the approach was confirmed in vivo using CBX-11, which was safely administered with cytotoxic chemotherapies to selectively kill both HRD-positive and HRD-negative tumors with significant sparing of bone marrow.

Per Hellsund, President and CEO of Cybrexa, commented, “These preclinical results highlight an entirely new approach to applying PARP inhibitors against solid tumors independent of HRD status and directly support our Phase 1 clinical trial evaluating CBX-11 in combination with chemotherapy, which is planned to start in the first quarter of 2020. Furthermore, our alphalex™ platform approach can be applied to a diverse range of DNA damage repair inhibitors to enable combinations with chemotherapy and chemo-radiation in a tissue-agnostic manner and we look forward to discussing these applications.”

Per Hellsund, President and CEO of Cybrexa, commented, “At Cybrexa, our mission is to develop new treatment options for patient populations with high unmet need. Based on preclinical data, we believe our alphalex™ technology will be able to successfully combine a potent PARP inhibitor with chemotherapy to enable more efficacious therapeutic combinations in new patient populations. To that end, we are very excited to share the potential of our technology at the upcoming DNA Damage Response Therapeutics Summit.”

About the alphalex™ Technology Platform

The Cybrexa alphalex™ technology platform enables the delivery of small molecules across the cell membrane under low pH conditions, which is a universal feature of cancer cells. As a result, alphalex™ technology – which consists of a novel peptide, linker and small molecule anti-cancer agent – allows for antigen-independent, intracellular delivery of small molecule anti-cancer agents directly into the tumor cell.
