WILMINGTON, Del., Nov. 10, 2020 (GLOBE NEWSWIRE) -- Prelude Therapeutics Incorporated (“Prelude”, “the Company”, “we”) (Nasdaq: PRLD), a clinical-stage precision oncology company, today announced its financial results for the third quarter ended September 30, 2020 and provided an update on recent developments.
“Prelude has evolved substantially to become a clinical-stage precision oncology company with multiple small molecule oral agents currently advancing through clinical trials,” said Kris Vaddi, PhD, Chief Executive Officer, Prelude Therapeutics. “We continue to make great progress in advancing the clinical development of our lead PRMT5 inhibitors, PRT543 and PRT811, and believe we are well-positioned for continued success with the execution of these programs. We look forward to sharing additional data from each program in 2021."
Dr. Vaddi added, "Beyond our PRMT5 program, we recently advanced our third product candidate, MCL1 inhibitor PRT1419, into the clinic for patients with hematologic malignancies, while our discovery engine continues to generate a diverse and robust pipeline. On the heels of our recent initial public offering resulting in gross proceeds of $181.9 million, we look forward to achieving additional clinical and regulatory milestones in the coming quarters.”
Clinical Program Highlights
- Dose Expansion Portion of Phase 1 Trial to Commence by Year-End. The Company remains on track to commence the expansion portion of its Phase 1 trial of its lead product candidate, PRT543, which is designed to be a potent, selective, and oral inhibitor of PRMT5, in select solid tumor cohorts during the fourth quarter of 2020 and in select myeloid malignancy cohorts in early 2021. The expansion cohorts will include patients with adenoid cystic carcinoma (ACC), myelofibrosis (MF), genomically-selected myelodysplastic syndrome (MDS), and homologous recombination deficient positive (HRD+) tumors. Preliminary data from the dose escalation portion of the trial demonstrated early signs of clinical activity and tolerability, including a durable confirmed complete response (CR) in a patient with HRD+ high grade serous ovarian cancer who had received seven prior lines of therapy. The Company anticipates obtaining initial clinical data from these expansion cohorts in the first half of 2021 and presenting these data at medical meetings in 2021.
- Dose Escalation Ongoing in Phase 1 Trial in Patients with Advanced Solid Tumors and Recurrent High-Grade Gliomas. The dose escalation portion of the Company’s Phase 1 trial of its second clinical product candidate, PRT811, which is designed to be a potent, selective, and brain penetrant PRMT5 inhibitor, in patients with advanced solid tumors, including glioblastoma multiforme (GBM) and primary central nervous system lymphomas (PCNSL), remains ongoing. To date, the trial has demonstrated early signs of clinical activity and tolerability. The previously disclosed refractory GBM patient whose tumor had demonstrated a 66% reduction on monotherapy PRT811 has subsequently undergone a follow-up MRI at week 16 confirming a partial response (PR) per RANO (response assessment in neuro-oncology) criteria. The Company expects to commence the dose expansion portion of the trial in the first half of 2021, with data expected by the end of 2021.
- Dosed First Patient in Phase 1 Trial of MCL1 Inhibitor PRT1419 for the Treatment of Relapsed/Refractory Hematologic Malignancies. In September 2020, Prelude announced dosing of the first patient in its first-in-human Phase 1 open-label, multicenter, dose-escalation study of PRT1419 in patients with relapsed/refractory hematologic malignancies. PRT1419, the Company’s third clinical candidate, is designed to be an orally available, potent, and selective MCL1 inhibitor.
- Completed Initial Public Offering (IPO). In September 2020, Prelude closed its IPO of 9,573,750 shares of common stock, including the full exercise of the underwriters’ option to purchase up to 1,248,750 additional shares of common stock, at a public offering price of $19.00 per share. Aggregate gross proceeds to Prelude were approximately $181.9 million, before deducting underwriting discounts and commissions and other offering expenses of $15.3 million.
- Strengthened Board of Directors with Two New Appointments. In August 2020, the Company announced the appointment of Mardi C. Dier and Victor Sandor, M.D., both highly accomplished industry veterans, to its Board of Directors.
Third Quarter 2020 Financial Results
- Cash and cash equivalents: Cash and cash equivalents as of September 30, 2020 were $234.8 million.
- Research and Development (R&D) Expenses: For the third quarter of 2020, R&D expenses increased by $9.8 million to $15.3 million compared to $5.5 million for the third quarter of 2019. The increase was mainly due to increased clinical research costs for the PRT543 and PRT811 clinical trials and increased costs associated with the initiation of the clinical trial for PRT1419, which began in the third quarter of 2020. Prelude also incurred an increase in chemistry, manufacturing, and other costs for those trials.
- General and Administrative (G&A) Expenses: For the third quarter of 2020, G&A expenses increased by $1.5 million to $2.9 million compared to $1.4 million for the third quarter of 2019. The increase was primarily due to an increase in personnel related expense due to increases in employee headcount and an increase in professional fees as Prelude expanded its operations to support its research and development efforts and incurred additional costs to operate as a public company.
- Net Loss: For the third quarter of 2020, net loss was $16.8 million, or $5.25 per share, compared to a net loss of $6.7 million, or $3.93 per share, for the third quarter of 2019.
