WILMINGTON, Del., March 16, 2021 (GLOBE NEWSWIRE) -- Prelude Therapeutics Inc. (“Prelude”, “the Company”, “we”, “our”) (Nasdaq: PRLD), a clinical-stage precision oncology company, today announced its financial results for the fourth quarter and full year ended December 31, 2020 and provided an update on recent developments.
“2020 marked a highly transformational year for Prelude with the successful completion of an initial public offering and progress across our three clinical-stage programs,” said Kris Vaddi, PhD, Chief Executive Officer of Prelude Therapeutics. “We are firmly committed to bringing novel therapies to patients in areas of high unmet need, and we have entered 2021 with both the momentum and resources that we believe will carry us through several key milestones. Notably, we are pleased to announce the completion of dose escalation activities in our ongoing Phase 1 trial of PRT543, our lead PRMT5 inhibitor, in patients with advanced solid tumors and hematologic malignancies, and that we will soon begin initiating additional expansion cohorts. We look forward to sharing clinical data for this program, as well as for our second PRMT5 inhibitor, PRT811, in the second half of this year.”
Dr. Vaddi added, “The ongoing Phase 1 trial of our third clinical candidate, PRT1419, an MCL1 inhibitor, also continues to progress, with the addition of dose expansion cohorts expected in the second half of the year. Finally, the continued advancement of our preclinical programs remains a high priority for us in 2021, with the anticipated submission of an IND application for PRT2527, our CDK9 inhibitor, in the second half of this year.”
Recent Highlights and Upcoming Milestones
PRT543
- Phase 1 Dose Escalation Complete; Additional Expansion Cohorts to Open in the Second Quarter. The Company today announced that the dose escalation portion of the Phase 1 trial of its lead product candidate, PRT543, is now complete, and that a recommended expansion dose with adequate safety, pharmacokinetics, and target engagement profile has been established. PRT543 is designed to be a potent, selective, and oral inhibitor of PRMT5. The dose expansion portion of the Phase 1 trial is currently open for the patient cohort with adenoid cystic carcinoma, and will be open for additional patient cohorts with solid tumor and hematologic malignancies early in the second quarter. As previously announced, preliminary data from the dose escalation portion of the trial demonstrated early signs of clinical activity and tolerability. The Company anticipates presenting initial clinical data from the Phase 1 trial at medical meetings in the second half of 2021.
- Preclinical Data to be Featured at the 2021 AACR Annual Meeting. Three preclinical presentations on PRT543 will be featured at the upcoming American Association for Cancer Research (AACR) Annual Meeting being held April 10-15, 2021 in a virtual setting. A copy of the posters, titled “PRMT5 inhibition downregulates MYB and NOTCH1 signaling, key molecular drivers of adenoid cystic carcinoma” (abstract 1138), “PRMT5 inhibition epigenetically regulates DNA damage response pathways in cancer cells and sensitizes to chemotherapy and PARP inhibition” (abstract 1185), and “PRMT5 inhibition regulates alternative splicing and DNA damage repair pathways in SF3B1 R625C expressing uveal melanoma cells” (abstract 1137), will be available in the Publications section of the Prelude Therapeutics website following the conclusion of the meeting.
PRT811
- Phase 1 Dose Expansion Cohorts Expected to Commence in Mid-2021. 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), remains ongoing. As previously reported, the trial has demonstrated early signs of clinical activity and tolerability. Prelude remains on track to establish the recommended expansion dose and commence the dose expansion portion of the trial in mid-2021 in patients with central nervous system cancers including GBM, with initial clinical data expected by the end of 2021.
PRT1419
- Oral Formulation: Dose Expansion and Combination Cohorts Expected to be Added to Ongoing Phase 1 Trial in the Second Half of 2021. The dose escalation portion of the Company’s first-in-human Phase 1 open-label, multicenter, dose-escalation study of oral PRT1419 in patients with relapsed/refractory hematologic malignancies, including acute myeloid leukemia and high-risk myelodysplastic syndromes, remains ongoing. PRT1419, which is the Company’s third clinical candidate, is designed to be an orally available, potent, and selective MCL1 inhibitor. The Company expects to add dose expansion and combination cohorts to the Phase 1 clinical trial in the second half of 2021.
- IV Formulation: IND Application Cleared. Prelude today announced the recent U.S. Food and Drug Administration (FDA) clearance of the Company’s Investigational New Drug (IND) application for an intravenous (IV) formulation of PRT1419. A Phase 1 trial of the IV formulation, which leverages the optimized physicochemical properties of PRT1419, is expected to commence in the first half of 2021 in patients with solid tumors.
- Data on Preclinical Characterization to be Featured at the 2021 AACR Annual Meeting. Data on the preclinical characterization of PRT1419 will be featured during a poster session at the 2021 AACR Annual Meeting. A copy of the poster, titled “Preclinical characterization of PRT1419, a potent, selective and orally available inhibitor of MCL1” (abstract 983), will be available in the Publication section of the Prelude Therapeutics website following the conclusion of the meeting.
Discovery Programs
- Advancement of Earlier-Stage Candidates Expected in 2021. Prelude remains on track to submit an IND application for PRT2527, which is designed to be a potent and selective CDK9 inhibitor, in 2021. The Company also continues to expect to initiate IND-enabling studies for PRT-SCA2, which is designed to be a SMARCA2 protein degrader, in 2021.
- Preclinical Data on SMARCA2 Protein Degradation to be Featured at the 2021 AACR Annual Meeting. A poster presentation on Prelude’s SMARCA2 protein degradation program, titled “Potent SMARCA2 targeted degraders induce genetic synthetic lethality in SMARCA4 deleted cancer” (abstract 1139), will be presented at the 2021 AACR Annual Meeting. A copy of the poster will be available in the Publications section of the Prelude Therapeutics website following the conclusion of the meeting.

$218.3 million . - Research and Development (R&D) Expenses: For the fourth quarter of 2020, R&D expense increased to
$14.6 million from$8.8 million for the prior year period, and for the full year increased to$48.2 million compared to$24.3 million for 2019.
