"As we direct our efforts and resources toward our ADC technologies and programs, we are committed to advancing VIP943 based on the encouraging safety, efficacy, and tolerability results observed to date. We look forward to presenting additional data from patients at efficacious dose cohorts by early next year," said Ahmed Hamdy, M.D., Chief Executive Officer. "Securing the funding necessary to advance our programs remains a priority. Alongside exploring financing options, we remain focused on strategic partnerships, particularly as pharmaceutical companies intensify their search for truly differentiated and transformative technologies."
THIRD QUARTER 2024 CLINICAL PROGRAM HIGHLIGHTS AND ANTICIPATED MILESTONES
VIP943
VIP943 is a novel CD123-targeted ADC developed with the Company’s next-generation VersAptx platform.
VIP943 has shown promising safety, efficacy, and tolerability in an ongoing Phase 1 dose-escalation study for patients with relapsed/refractory acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and B-cell acute lymphoblastic leukemia (B-ALL) (NCT06034275). In October, the Company reported two complete responses in this Phase 1 study: one out of four patients with relapsed AML in the 1 mg/kg dose cohort achieved complete remission with incomplete hematologic recovery (CRi), and one out of one patient with higher-risk MDS in the 1.3 mg/kg dose cohort achieved complete remission with limited count recovery (CRL).
VIP943 has shown effective target engagement and elimination of CD123+ malignant cells, with pharmacodynamic data demonstrating decreases in CD123+ blasts after dosing. Preliminary pharmacokinetic data indicates minimal payload release (≤1% in plasma), signifying a stable linker.
Given the favorable safety and tolerability observed for VIP943, the Company continues dose escalation to assess potential for additional efficacy. Enrollment in the once-weekly and twice-weekly (as an induction therapy) dosing schedules is ongoing.
Vincerx expects to share additional Phase 1 study data for VIP943 by early 2025.
Enitociclib
Enitociclib is a highly selective CDK9 inhibitor designed to block the activation of RNA polymerase II, leading to inhibition of oncogenes, including MYC and MCL1.
Enitociclib is currently in a Phase 1 dose-escalation study (NTC05371054) evaluating the combination of enitociclib, venetoclax, and prednisone in diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL). This study is being conducted in collaboration with the National Institutes of Health (NIH). As of September 2024, the study reported four partial responses (PRs) in seven patients (57% overall response rate), including one patient with double hit lymphoma (DH-DLBCL) and three patients with PTCL.
Enitociclib has successfully completed its Phase 1 dose-escalation study as a monotherapy (NCT02635672), enrolling 63 patients across dose-escalation and expansion cohorts. The treatment demonstrated a favorable safety profile, dose-proportional pharmacokinetics, and on-target pharmacodynamic activity. Clinical benefits included durable complete metabolic remissions in two patients with DH-DLBCL, lasting 3.7 and 2.3 years, with both remissions continuing more than two years after treatment cessation. In addition, a transformed follicular (tFL) patient achieved a PR with a 63% tumor reduction after nearly two years, a meaningful outcome given the historically poor prognosis of tFL. Furthermore, 13 patients with solid tumors achieved stable disease as their best response, including five ovarian cancer patients—indicating a promising path for future combination studies in this indication.
The Company is actively focused on finding a strategic partner to continue the development of this asset.
VIP236
VIP236 is a αVβ3 SMDC conjugated to an optimized camptothecin (CPT) payload developed with the Company’s VersAptx platform.
VIP236 has completed its Phase 1 dose-escalation study (NCT05712889), identifying the maximum tolerated dose that could be utilized in future studies. As reported in October, a total of 29 patients were enrolled in the Phase 1 study, resulting in a 45% disease control rate. The drug demonstrated a favorable safety profile, distinguishing itself from other CPTs by showing no instances of common dose-limiting side effects such as life-threatening diarrhea, severe stomatitis/mucositis, or interstitial lung disease.
The Company intends to identify a partner to champion VIP236 through further development.
THIRD QUARTER 2024 FINANCIAL RESULTS
Vincerx had approximately $10.1 million in cash, cash equivalents, and marketable securities as of September 30, 2024, as compared to approximately $16.3 million as of June 30, 2024. Based on its current business plans and assumptions, Vincerx believes its available capital will be sufficient to meet its operating requirements into early 2025.
Research and development expenses for the third quarter ended September 30, 2024, were approximately $3.9 million, as compared to approximately $6.1 million for the same period in 2023. This decrease is primarily the result of decreases in research services of approximately $2.4 million and personnel-related expenses of approximately $0.8 million, offset by an increase in clinical-related expenses of approximately $0.9 million.
General and administrative expenses for the third quarter ended September 30, 2024, were approximately $3.9 million, as compared to approximately $3.5 million for the same period in 2023. This increase was due to a $0.5 million increase in professional services, partially offset by a decrease in personnel-related expenses of $0.1 million.
For the third quarter ended September 30, 2024, Vincerx reported a net loss of approximately $7.8 million, or $0.17 per share. For the third quarter ended September 30, 2023, Vincerx reported a net loss of approximately $9.0 million, or $0.42 per share.
