VINC Vincerx Inc

Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, today announced it will present three posters at the American Association for Cancer Research (AACR) Annual Meeting 2024, taking place in San Diego, CA, from April 5 – 10, 2024. Vincerx will also share clinical data for VIP236 at the conference.

“We are extremely pleased to highlight the continued development of our next-generation VersAptx™ bioconjugation platform in these three abstract/poster presentations,” said Ahmed Hamdy, M.D., Chief Executive Officer of Vincerx. “In addition to the preclinical results of our VersAptx platform, our SMDC poster (#3197) will also present, for the first time, early clinical results for VIP236. To date, 20 patients with relapsed/refractory advanced or metastatic solid tumors have been treated with two different dosing schedules of VIP236. The poster will summarize preliminary safety, efficacy, and pharmacokinetic results from this first-in-human, dose-escalation study (NCT05712889).”Virtual Investor Event:

Vincerx will host a virtual investor event featuring company management and key opinion leaders on Monday, April 8, 2024. The event will be webcast live, and details can be accessed in the Investor Calendar section of the Vincerx website on March 27, 2024. An archived replay will be available shortly after the conclusion of the live event.

About VIP236

VIP236, the first-in-class small molecule drug conjugate (SMDC) from our VersAptx Platform, consists of an αvβ3 integrin binder, a neutrophil elastase linker cleaved in the tumor microenvironment, and a camptothecin payload optimized for high permeability and low efflux. VIP236 was designed to deliver its payload to advanced/metastatic tumors that express αvβ3. Preclinical data show enhanced efficacy, independent of HER2 status, in patient-derived and cell line-derived gastric cancer models compared with ENHERTU®, an approved ADC. VIP236 is being evaluated in a Phase 1 dose-escalation trial treating patients with advanced or metastatic solid tumors (NTC05371054). As VIP236 is a first-in-class drug, the Phase 1 trial is evaluating various dosing schedules. To date, 20 patients with advanced or metastatic disease that has relapsed or is refractory to standard of care have received VIP236.

About VIP943

VIP943, the first ADC from our VersAptx platform, consists of an anti-CD123 antibody, a unique linker cleaved intracellularly by legumain, and a novel kinesin spindle protein inhibitor (KSPi) payload enhanced with our CellTrapper® technology. Our proprietary effector chemistry (linker + payload) was designed to reduce non-specific release of the payload and ensure payload accumulation in cancer cells versus healthy cells. The increased therapeutic index has the potential to address challenges associated with many ADCs by improving efficacy and reducing severe toxicities. VIP943 is in a Phase 1 dose-escalation trial evaluating patients with relapsed/refractory acute myeloid leukemia, myelodysplastic syndrome, and B-cell acute lymphoblastic leukemia who have exhausted standard therapeutic options (NCT06034275). Preliminary pharmacokinetic data from the first cohort shows low levels of unconjugated payload (VIP716) in circulation, as predicted from preclinical experiments. Reduced nonspecific release of payload is one of many features engineered into VIP943 to increase the therapeutic index compared with existing technologies. We expect to expand into additional CD123-positive indications, including TP53 mutated AML, both as monotherapy and in combination, as safety and efficacy data are generated. Preliminary Phase 1 data are expected in mid-2024.

About VersAptx Platform

VersAptx is our versatile and adaptable next-generation bioconjugation platform. The modular nature of this innovative platform allows us to combine different targeting, linker, and payload technologies to develop bespoke bioconjugates to address different cancer biologies. With this platform, (i) antibodies and small molecules can be used to target different tumor antigens, (ii) linkers can be designed to reduce non-specific release of the payload, cleave intracellularly or extracellularly, and conjugate to single or multiple payloads, and (iii) payloads can be designed with reduced permeability using our CellTrapper technology to ensure accumulation in cancer cells or to be permeable for release in the tumor microenvironment. The VersAptx platform allows us to optimize these technologies to a specific target and develop bioconjugates designed to address the safety and efficacy challenges of many ADCs and the needs of cancer patients.
