First-in-class IV SMARCA2 degrader, PRT3789 and potentially best-in-class CDK9 inhibitor, PRT2527 remain on track to generate initial proof-of-concept data in 2024
New preclinical data presented at AACR 2024 included first characterization of PRT7732, a highly-selective, orally bioavailable SMARCA2 degrader
Operational leadership capabilities further strengthened by recent hires Chief Business Officer Sean Brusky and Senior Vice President, Investor Relations Robert Doody
Current cash runway into 2026 with $201.9 million in cash, cash equivalents and marketable securities as of March 31, 2024
WILMINGTON, Del., May 07, 2024 (GLOBE NEWSWIRE) -- Prelude Therapeutics Incorporated (Nasdaq: PRLD), a clinical-stage precision oncology company, today reported its financial results for the first quarter ended March 31, 2024 and provided an update on recent clinical development pipeline and other corporate developments.
“The first quarter of this year was marked by growing momentum for Prelude, led by the continued clinical progress of our two lead drug candidates, PRT3789, a highly-selective, first-in-class SMARCA2 degrader and PRT2527, a potentially best-in-class CDK9 inhibitor,” stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. “We are on track to present initial Phase 1 data for both compounds in the second half of this year and to advance both into the next phase of development in cancers with patients who are in need of safe and effective new therapies, provided the data are supportive.”
Dr. Vaddi continued, “In addition to the continued advancement of our clinical compounds, we strengthened our leadership team with the additions of Sean Brusky, our new Chief Business Officer and Robert Doody, our new head of Investor Relations, both of whom bring proven operational capabilities and important strategic insights to the Prelude team in anticipation of our expected progress and growth over the coming years.”
Clinical Program Updates and Upcoming Milestones
SMARCA2 degrader PRT3789 on track to complete monotherapy dose escalation mid- year and combination with docetaxel has been initiated; initial proof-of concept data expected in second half of 2024.
PRT3789 is a potent and highly selective, first-in-class SMARCA2 degrader, designed to be used in patients with a SMARCA4 mutation. Cancers with a SMARCA4 mutation represent a high unmet medical need. Patients with the SMARCA4 mutation have poor prognosis and limited treatment options.
PRT3789 is in Phase 1 clinical development in biomarker selected SMARCA4 mutant patients. Enrollment remains on track, and the Company expects to conclude monotherapy dose escalation mid-2024 and identify recommended Phase 2 dose. In addition, enrollment of patients into back-fill cohorts enriched for NSCLC and SMARCA4 loss-of-function mutations is ongoing. Objectives for this first Phase 1 clinical trial are to establish the safety and tolerability profile of PRT3789 as both monotherapy and in combination with docetaxel, evaluate activity, pharmacokinetics and pharmacodynamics and determine a dose and potential indications for advancement into a registrational clinical trial.
Oral SMARCA2 degrader PRT7732 expected to enter Phase 1 clinical trial in the second half of 2024
Prelude’s discovery team has identified a series of highly selective and orally bioavailable SMARCA2 degraders. The lead oral molecule, PRT7732, is currently in investigational new drug (IND) enabling preclinical studies and on track to enter Phase 1 clinical development in the second half of 2024. PRT7732 is structurally distinct from PRT3789 and may provide clinically meaningful differences, including potential utility in earlier lines of therapy.
CDK9 inhibitor PRT2527 on track to complete monotherapy dose escalation mid-2024; initiated dosing in combination with zanubrutinib in first quarter of 2024; initial hematological proof-of-concept data expected in second half of 2024
PRT2527 is a potent and selective CDK9 inhibitor that has the potential to avoid off target toxicity. The Company is currently advancing PRT2527 as monotherapy in hematological indications such as B-cell malignancies and acute myeloid leukemia (AML) and has initiated the combination with zanubrutinib in B-cell malignancies.
PRT2527 is currently in Phase 1 clinical development and is expected to complete monotherapy dose escalation in B-cell malignancies mid-year. A second cohort of patients with AML is expected to initiate in the first half of 2024.
2024 AACR Annual Meeting: Prelude participated in the 2024 American Association for Cancer Research Annual Meeting, presenting three preclinical poster presentations. New preclinical data was presented for the company’s highly selective oral SMARCA2 degrader, its potentially best-in-class CDK9 inhibitor, and its next-generation oral CDK4/6 inhibitor. Copies of this information can be found on the Company’s website under Publications - Prelude Therapeutics (preludetx.com).
Corporate Updates: In April 2024, Prelude appointed Sean Brusky to the newly created position of Chief Business Officer. Mr. Brusky joins Prelude from Pardes Biosciences where he served as both Chief Commercial Officer and Chief Business Officer. Prior to Pardes, Mr. Brusky served in roles of increasing seniority at Genentech/Roche, Vertex Pharmaceuticals and Bain & Company.
Additionally, in April 2024, Prelude appointed Robert Doody to the newly created position of Senior Vice President, Investor Relations. Mr. Doody most recently served as Head of Investor Relations at Aclaris Therapeutics. Prior to Aclaris Therapeutics, Mr. Doody served as Investor Relations Lead at Provention Bio, Idera Pharmaceuticals and ViroPharma Incorporated.
First Quarter 2024 Financial Results
Cash and Cash Equivalents: Cash, cash equivalents and marketable securities as of March 31, 2024 were $201.9 million. The Company anticipates that its existing cash, cash equivalents and marketable securities will fund Prelude’s operations into 2026.
Research and Development (R&D) Expenses: For the first quarter of 2024, R&D expense increased to $27.4 million from $21.8 million for the prior year period. Research and development expenses increased primarily due to the timing of our clinical research programs. We expect our R&D expenses to vary from quarter to quarter, primarily due to the timing of our clinical development activities.
General and Administrative (G&A) Expenses: For the first quarter of 2024, G&A expenses decreased to $6.9 million from $7.3 million for the prior year period. The decrease is primarily due to a decrease in non-cash expense related to stock-based compensation, partially offset by an increase in professional fees incurred as we expand our operations to support our research and development efforts.
Net Loss: For the three months ended March 31, 2024, net loss was $31.4 million, or $0.42 per share compared to $27.7 million, or $0.58 per share, for the prior year period. Included in the net loss for the quarter ended March 31, 2024, was $5.5 million of non-cash expenses related to the impact of expensing share-based payments, including employee stock options, as compared to $6.3 million for the same period in 2023.
