PALO ALTO, Calif., March 28, 2023 (GLOBE NEWSWIRE) -- Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, today reported financial results for the fourth quarter and full year ended December 31, 2022, and provided a corporate update.

“Vincerx made great progress in 2022, advancing multiple programs while moving closer towards achieving our mission of improving outcomes for patients with cancer,” said Ahmed Hamdy, M.D., Chief Executive Officer of Vincerx. “We are particularly excited with the advancements we have made with our bioconjugation platform. This quarter, we started dosing the first cohort in our Phase 1 dose-escalation study in advanced solid tumors for VIP236, our first-in-class, front-runner α_vβ₃ SMDC with a tailored design to efficiently target aggressive and metastatic cancers. To date, we have generated robust preclinical results demonstrating how VIP236 can deliver up to 40 times more drug to the cancer, while sparing the surrounding tissues and normal organs. We look forward to sharing preclinical data at the upcoming AACR meeting, highlighting how VIP236 showed monotherapy efficacy in non-small cell lung cancer (NSCLC), gastric cancer, triple negative breast cancer (TNBC), renal cell carcinoma (RCC), colorectal cancer (CRC), and metastatic TNBC in vivo cancer models. Additionally, we will share exciting preclinical data in gastric cancer, where VIP236 showed improved efficacy in vivo compared with ENHERTU®, an approved ADC.”

“There have been some exciting developments in the ADC space recently, and our team has done great work positioning Vincerx to be a key player through the development and advancement of our next-generation, modular bioconjugation platform. Our lead ADC is VIP943, a novel anti-CD123 antibody that combines a unique payload class of kinesin spindle protein inhibitors (KSPi), a proprietary legumain-cleavable linker, and our CellTrapper™ modification of the KSPi, which allows for intracellular accumulation. CD123 is a validated target in myeloid malignancies, including higher-risk myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), which are the first indications we are pursuing. MDS and AML are aggressive and heterogeneous in their genetic makeup, and current treatments are quite toxic with high rates of relapse. This past ASH, we presented exciting preclinical data where, for the first time, we showed that our KSPi payload, linker and CellTrapper technology had a significant improvement in safety over Mylotarg™, an approved ADC for the treatment of AML. We also showed that VIP943 did not cause cytokine release in human blood cells. This indicates a potential reduced risk in the clinic for cytokine release syndrome, which is a common side effect of other CD123 targeting dugs (eg, ADCs and bispecifics). We believe these preclinical results, especially the improved safety over Mylotarg, demonstrate the benefit of our technology, which was designed to address some of the well-known challenges of existing ADCs. We remain on track to file the IND for VIP943 by mid-2023 and expect to get VIP943 into the clinic in the second half of this year,” added Dr. Hamdy.

“We also remain excited about enitociclib, our CDK9 inhibitor, and anticipate dosing the first patient in our Phase 1b enitociclib combination study with an approved BTK inhibitor in CLL next quarter. While great progress has been made in the treatment of CLL, limiting patients’ exposures to toxicities, preventing resistance, and minimizing risk of relapse and death following prolonged BTK inhibition monotherapy remain unmet needs. Our objective in the Phase 1b study is to put patients on a time-limited treatment, thus reducing their exposure to toxicities and preventing resistance to the BTK inhibitor,” concluded Dr. Hamdy.

FOURTH QUARTER AND FULL YEAR 2022 CORPORATE HIGHLIGHTS
