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 plans to implement cost-controls and explore strategic alternatives to support advancing the Phase 1 study of VIP943, the Company’s novel CD123-targeted antibody-drug conjugate (ADC) developed with the Company’s next-generation VersAptx™ platform.

“We believe VIP943 is a highly differentiated and valuable asset, and we remain fully committed to advancing this program,” said Ahmed Hamdy, M.D., Chief Executive Officer. “As we shared in October, the Phase 1 dose-escalation study of VIP943 has demonstrated encouraging safety, efficacy, and tolerability. Of nine evaluable patients, one patient whose acute myeloid leukemia (AML) relapsed post-transplant achieved a CRi and one patient with higher-risk myelodysplastic syndrome (HR-MDS) achieved a CRL. Notably, since October, the patient with CRi has continued to improve, with their most recent bone marrow results showing only 1% cancer cells. This patient has now been on the study for seven months and counting. Monotherapy responses in post-transplant patients are rare, so we believe this type of response highlights the potential of VIP943 in this challenging population and supports the next-generation technology of our VersAptx platform.”

Dr. Hamdy continued, “Our immediate focus is to give the program time to generate more data, with results from additional cohorts expected by early Q1 2025. To support this, we are implementing significant cost-cutting measures to focus resources on VIP943’s advancement. Additionally, we will begin exploring strategic alternatives to complement our ongoing fundraising efforts, with the goal of maximizing the value of the VIP943 program and our VersAptx platform.”

As part of its review of potential strategic alternatives, Vincerx will consider options such as out-licensing, merger and acquisition opportunities, including reverse mergers, sales of assets and technologies, and other transactions. To streamline operations and focus resources, Vincerx will implement a significant reduction in force of approximately 55%. There can be no assurance that the exploration of strategic alternatives will result in any agreements or transactions, or as to the timing of any such agreements or transactions. The Company is in the process of engaging a financial advisor to assist in the strategic review process.

Vincerx has not set a timetable for completion of the evaluation process and does not intend to disclose further developments or guidance on the status of its exploration of strategic alternatives unless and until it is determined that further disclosure is appropriate or necessary.

As of October 31, 2024, the Company had approximately $8.4 million in cash, cash equivalents, and marketable securities.

About VIP943VIP943, the first ADC from the 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 Vincerx’s CellTrapper™ technology. Vincerx’s 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 being evaluated in a Phase 1 dose-escalation trial in patients with relapsed/refractory AML, HR-MDS, and B-ALL who have exhausted standard therapeutic options (NCT06034275).

About VersAptx PlatformVersAptx is a versatile and adaptable next-generation bioconjugation platform. The modular nature of this innovative platform allows the combination of different targeting, linker, and payload technologies to develop bespoke bioconjugates that 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 the development of bioconjugates designed to address the safety and efficacy challenges of historical ADCs.
