This phase II trial studies how well CBX-12 works in treating patients with microsatellite stable colorectal cancer that has spread to other parts of the body (metastatic) and is no longer responding to chemotherapy treatment (chemotherapy-refractory). The usual approach to treating colorectal cancer includes treatment with surgery, radiation, or Food and Drug Administration (FDA)-approved drugs such as trifluoridine-tiparacil, bevacizumab, regorafenib, or fruquintinib. However, most metastatic colorectal patients progress through all approved treatments and eventually succumb to their disease. CBX-12 is a drug that contains a peptide (a substance that contains many amino acids [molecules that join together to form proteins]) called pHLIP, linked to an anticancer substance called exatecan. Upon administration, pHLIP gets inserted into the cellular membrane of tumor cells, delivering exatecan to kill them. Giving CBX-12 may work better than the usual approach in treating patients with metastatic chemotherapy-refractory microsatellite stable colorectal cancer.

Pilot Study of CBX-12 Pharmacodynamics in Patients With Advanced Solid Tumors

This phase I trial studies how well CBX-12 works in treating patients with solid tumors that have spread from where they first started (primary site) to started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or other places in the body (metastatic). CBX-12 works by binding to a protein called TOP1 that is present inside the cells. This allows CBX-12 to kill the cancer cells by damaging their DNA, resulting in cancer cell death. This trial is being done to find out if this approach is better or worse than the usual approach for advanced cancers.

Antigen-Independent Tumor Targeting by CBX-12 (Alphalex ^™ –Exatecan) Induces Long-Term Antitumor Immunity

Article

作者: Jones, Kelli ; Paralkar, Vishwas M ; Paradis, Timothy ; Vasquez, Juan ; Gayle, Sophia

Aims: To determine whether antigen-independent targeting of the TOP1 inhibitor exatecan to tumor with a pH-sensitive peptide (CBX-12) produces superior synergy with immunotherapy compared with unconjugated exatecan. Materials & methods: In vitro and ex vivo functional assays were performed via FACS and ELISA assays. In vivo efficacy was evaluated in the syngeneic CT26 model. Results: CBX-12 combined with anti-PD-1 or anti-CTLA4 results in delayed tumor growth and complete response, with cured animals displaying long-term antitumor immunity. CBX-12 stimulates expression of MHC 1 and PD-L1 and is an inducer of immunogenic cell death, producing long-term immune recognition of tumor cells and resultant antitumor immunity. Conclusion: The authors' data provide the rationale for exploring immunotherapy combinations with CBX-12 in clinical trials.

Abstract:

Exatecan and deruxtecan are antineoplastic camptothecin derivatives in development as tumor-targeted-delivery warheads in various formulations including peptides, liposomes, polyethylene glycol nanoparticles, and antibody–drug conjugates. Here, we report the molecular pharmacology of exatecan compared with the clinically approved topoisomerase I (TOP1) inhibitors and preclinical models for validating biomarkers and the combination of exatecan with ataxia telangiectasia and Rad3-related kinase (ATR) inhibitors. Modeling exatecan binding at the interface of a TOP1 cleavage complex suggests two novel molecular interactions with the flanking DNA base and the TOP1 residue N352, in addition to the three known interactions of camptothecins with the TOP1 residues R364, D533, and N722. Accordingly, exatecan showed much stronger TOP1 trapping, higher DNA damage, and apoptotic cell death than the classical TOP1 inhibitors used clinically. We demonstrate the value of SLFN11 expression and homologous recombination (HR) deficiency (HRD) as predictive biomarkers of response to exatecan. We also show that exatecan kills cancer cells synergistically with the clinical ATR inhibitor ceralasertib (AZD6738). To establish the translational potential of this combination, we tested CBX-12, a clinically developed pH-sensitive peptide–exatecan conjugate that selectively targets cancer cells and is currently in clinical trials. The combination of CBX-12 with ceralasertib significantly suppressed tumor growth in mouse xenografts. Collectively, our results demonstrate the potency of exatecan as a TOP1 inhibitor and its clinical potential in combination with ATR inhibitors, using SLFN11 and HRD as predictive biomarkers.

Cybrexa Therapeutics Announces First Patient Dosed with First-in-Class Peptide-Drug Conjugate CBX-12 in Phase 2 Trial in Ovarian Cancer

Primary target patient population for the CBX-12 Phase 2 study is women with platinum-resistant or refractory ovarian cancer who are naïve to TOP1-targeted agents Study initiation follows positive Phase 1 study results, which showed a 40% response rate in TOP1-naïve ovarian cancer patients, in addition to activity across five other solid tumor types and a favorable safety profile Trial marks key milestone in driving pipeline progress with multiple Phase 2 programs planned for CBX-12 in 2025 as a monotherapy and in combination NEW HAVEN, Conn., Oct. 07, 2024 (GLOBE NEWSWIRE) -- Cybrexa Therapeutics, a clinical-stage oncology biotechnology company developing a novel class of tumor-targeting peptide-drug conjugate (PDC) therapeutics, today announced that the first patient has been dosed in a Phase 2 clinical trial evaluating CBX-12 in patients with platinum-resistant or refractory ovarian cancer. CBX-12 is a first-in-class PDC that uses Cybrexa’s proprietary alphalex™ technology to enhance the delivery of exatecan, a potent, established topoisomerase 1 (TOP1) inhibitor, directly to tumor cells while sparing healthy tissue. This trial initiation follows promising Phase 1 results, which demonstrated CBX-12’s broad activity across ovarian, breast, non-small cell lung cancer (NSCLC), thymic, gallbladder, and colorectal cancers along with a manageable safety profile. “Dosing the first patient marks an important milestone for the Phase 2 clinical trial in ovarian cancer and for patients facing this aggressive disease,” said Per Hellsund, President and Chief Executive Officer of Cybrexa. “CBX-12 recently demonstrated significant antitumor activity, broad application potential, and a favorable safety profile in a Phase 1 study, including encouraging response rates in TOP1-naïve ovarian and breast cancer patients. We are particularly excited about the potential for CBX-12 not only as a standalone treatment but also as a promising candidate for future combination therapies and look forward to its continued advancement in this and additional Phase 2 studies in solid tumors, which are planned for 2025.” The Phase 2 trial is a randomized, open-label study designed to evaluate the safety, tolerability, and efficacy of CBX-12 in women with platinum-resistant or refractory ovarian cancer at two doses: 125 mg/m2 every 21 days or 100 mg/m2 every 21 days. Cybrexa plans an additional Phase 2 study of CBX-12 in colorectal cancer in 2025 in collaboration with the National Cancer Institute (NCI), as well as other Phase 2 studies evaluating CBX-12 as a monotherapy and in combination across a range of solid tumors. Leveraging its alphalex platform to develop multiple promising assets in oncology, Cybrexa is progressing its broader pipeline, including CBX-15, which is expected to enter the clinic in 2025 for the treatment of solid tumors using MMAE (monomethyl auristatin E) as its payload. Unlike antibody-drug conjugates, CBX-12 does not rely on antigen expression for targeting but rather uses a pH-low insertion peptide (pHLIP ®) to selectively deliver its payload into the cytoplasm of cancer cells. Results from the Phase 1 study demonstrated that CBX-12 is well tolerated and exhibits promising activity across a range of advanced or metastatic solid tumors, highlighting the versatility of the alphalex platform and its ability to enhance the delivery of cancer therapeutics while limiting off-target effects. The Phase 1 study results were recently presented at the European Society for Medical Oncology Congress (ESMO 2024) in a poster session. To learn more about the Phase 2 study of CBX-12, please visit ClinicalTrials.gov (NCT06315491). About CBX-12CBX-12 is a first-in-class peptide-drug conjugate (PDC) that utilizes Cybrexa’s proprietary alphalex™ technology to enhance delivery of exatecan to tumor cells and is composed of a pH-Low Insertion Peptide (pHLIP®), a linker, and exatecan. CBX-12 is designed to increase the efficacy and reduce the toxicity of topoisomerase 1 inhibition by delivering exatecan, a highly potent, second-generation topoisomerase 1 inhibitor, directly to the tumor cells. As an antigen-independent therapy, CBX-12 may have broad utility in patients who are not eligible for antigen-targeted therapies, including monoclonal antibodies and antibody-drug conjugates (ADCs), and has potential for use in combination regimens with other anti-cancer agents and immunotherapies.
