WILMINGTON, Del., Aug. 12, 2024 (GLOBE NEWSWIRE) -- Prelude Therapeutics Incorporated (Nasdaq: PRLD), a clinical-stage precision oncology company, today reported its financial results for the second quarter ended June 30, 2024 and provided an update on its clinical development pipeline and other corporate developments.
“Our team continues to make solid progress towards the Company’s ambitious R&D objectives that we established for 2024 and beyond. We are focused on advancing our two lead clinical programs, including the first-in-class, highly selective SMARCA2 degrader, PRT3789 and a potent and selective CDK9 inhibitor, PRT2527, both on track to report initial clinical results this year,” stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude.
Dr. Vaddi continued, “We believe that targeting the SMARCA pathway has the potential to deliver a ‘pipeline in a program.’ We are building on our leadership position by advancing the industry’s first highly selective oral SMARCA2 degrader, PRT7732, into the clinic, and will initiate a study of PRT3789 in combination with KEYTRUDA in collaboration with Merck later this year. Additionally, in collaboration with AbCellera, we are developing precision ADCs with SMARCA payloads to extend the reach of our molecules to an even broader set of cancers without SMARCA4 mutations.”
“Regarding our clinical development programs, we are very pleased with the progress of both of our SMARCA2 degraders, PRT3789 and PRT7732,” added Jane Huang, M.D., President and Chief Medical Officer of Prelude. “We are looking forward to sharing the initial clinical data from the Phase 1 study of our highly selective SMARCA2 degrader which has been chosen as the subject of an oral presentation at the upcoming ESMO Congress in September.”
Dr. Huang continued, “Additionally, based on the continued progress of PRT2527, our selective CDK9 inhibitor, we intend to present interim phase 1 clinical data, including a potential best-in-class safety profile in the fourth quarter of this year.”
Clinical Program Updates and Upcoming Milestones
PRT3789 – A first-in-class, highly selective, intravenous SMARCA2 Degrader
PRT3789 is a first-in-class SMARCA2 degrader, highly selective for SMARCA2 and designed to treat patients with a SMARCA4 mutation. Cancer patients whose tumors have SMARCA4 mutations have a poor prognosis and as a result, this is an area of high unmet medical need.
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 in 2024 and identify a recommended Phase 2 dose. In addition, enrollment of patients into back-fill cohorts enriched for NSCLC and SMARCA4 loss-of-function mutations is ongoing, as is enrollment of the combination with docetaxel cohort.
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 registrational clinical trial(s).
Prelude recently launched an educational video series focused on the science of SMARCA biology, the discovery of first-in-class, highly selective SMARCA2 degraders and the unmet medical need for patients with SMARCA4 mutated cancer. This series can be found on the Company’s website under Highly Selective SMARCA2 Degraders - Prelude Therapeutics (preludetx.com).
Interim Phase 1 data selected for an oral presentation at the ESMO Congress 2024
The abstract titled “First Clinical Results from a Phase 1 Trial of PRT3789, a First-in-Class Intravenous SMARCA2 Degrader, in Patients with Advanced Solid Tumors with a SMARCA4 Mutation,” will be presented by Robin Guo, M.D. from Memorial Sloan Kettering Cancer Center. The ESMO Congress 2024 Scientific Committee selected the abstract as an oral presentation.
The presentation is scheduled for September 13th, 2024, at 4:00 PM CEST (10:00 AM EST) in the Santander Auditorium (Hall 5) as part of the Developmental Therapeutics Session.
Abstracts are anticipated to be available on the ESMO website on September 9th, 2024 at 12:05 AM CEST (6:05 PM EST on September 8th).
Clinical collaboration announced with Merck to evaluate PRT3789 in combination with KEYTRUDA? in patients with SMARCA4-mutated cancers
In July 2024, Prelude announced a clinical collaboration with Merck to evaluate PRT3789 in combination with KEYTRUDA? in patients with SMARCA4-mutated cancers.
The mechanistic rationale and pre-clinical data to support the SMARCA2 and anti-PD-1 monoclonal antibody (mAb) combination was previously presented by the Company at the 2023 AACR International Conference on Molecular Targets and Cancer Therapeutics. In pre-clinical models, SMARCA2 degrader combined with an anti-PD-1 mAb in SMARCA4-mutated cancers enhanced anti-tumor immunity and demonstrated tumor regressions. Please see the Company’s website under Publications - Prelude Therapeutics (preludetx.com) for more information.
Under the terms of the Agreement, Merck will provide KEYTRUDA? to Prelude. Prelude will be the sponsor of the Phase 2 clinical combination trial, anticipated to initiate in the fourth quarter of 2024. Prelude and Merck each retain all commercial rights to their respective compounds, including as monotherapy or as combination therapies.
KEYTRUDA? is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.
PRT7732 – A potent, highly selective and orally bioavailable SMARCA2 Degrader
Prelude has identified a series of highly selective and orally bioavailable SMARCA2 degraders. The lead oral candidate, PRT7732, recently was granted IND authorization from the FDA and is expected to enter Phase 1 clinical development in the second half of 2024.
PRT2527 – A potent and highly selective CDK9 Inhibitor
PRT2527 is a potent and highly selective CDK9 inhibitor that has the potential to avoid off-target toxicities observed with other less selective CDK9 inhibitors. The Company is currently advancing PRT2527 as monotherapy in both lymphoid and myeloid hematological malignancies, and in combination with zanubrutinib in B-cell malignancies.
PRT2527 is expected to complete monotherapy dose escalation in B-cell malignancies this year. Initiation of dose escalation in myeloid malignancies occurred in the first half of 2024. Interim Phase 1 data is on track for presentation in the fourth quarter of 2024.
Second Quarter 2024 Financial Results
Cash, Cash Equivalents, and Marketable securities:
Cash, cash equivalents and marketable securities as of June 30, 2024 were $179.8 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 second quarter of 2024, R&D expense increased to $29.5 million from $25.0 million for the prior year period. Research and development expenses increased primarily due to an increase in our chemistry, manufacturing, and controls (CMC) expense to support our pre-clinical and 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 second quarter of 2024, G&A expenses increased to $7.7 million from $7.4 million for the prior year period. The increase is primarily due to 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 June 30, 2024, net loss was $34.7 million, or $0.46 per share compared to $30.4 million, or $0.54 per share, for the prior year period. Included in the net loss for the quarter ended June 30, 2024, was $6.1 million of non-cash expenses related to the impact of expensing share-based payments, including employee stock options, as compared to $6.7 million for the same period in 2023.
