Prelude Therapeutics Secures $60 Million


WILMINGTON, Del.--(BUSINESS WIRE)--Prelude Therapeutics, a privately held, clinical-stage biopharmaceutical company focused on the discovery and development of small molecule drugs that target key drivers of cancer cell growth, survival and resistance, secured $60 million in Series B financing; taking its total investments to date to $95 million. The financing was co-led by Prelude’s two existing institutional investors, including OrbiMed Advisors LLC.

Since its launch in July 2016, Prelude has made rapid progress in its first discovery program targeting Protein Arginine Methyltransferase 5 (PRMT5), a member of the arginine methyltransferase family. PRMT5 plays an important role in several cellular processes that drive cancer cell proliferation, cell cycle progression and resistance to apoptosis in hematological malignancies and solid tumors.

Proceeds from the Series B financing will be used to advance Prelude’s proprietary PRMT5 inhibitor, PRT543, through proof of concept clinical studies. PRT543 is in a parallel dose escalation Phase 1 clinical trial for solid tumors, myeloid malignancies and lymphomas.

Series B funding will also be used to advance additional differentiated compounds from the PRMT5 program and strengthen Prelude’s discovery, preclinical and clinical development infrastructure to support a rapidly advancing pipeline beyond PRMT5. Prelude has established several drug discovery programs and compounds from these early-stage programs are also expected to enter preclinical development in the second half of 2019 with a potential IND-filing in 2020.

“We are very appreciative of the continued support of our current investors, who have been integral to the founding of Prelude and the creation of our growing pipeline,” said Kris Vaddi, PhD, Founder and CEO of Prelude Therapeutics. “We believe PRMT5 inhibitors represent a promising new class of drugs to treat cancers, including ones that have developed resistance to existing targeted therapies. We are also pleased to have assembled such a talented, experienced and proven leadership team to address some of the most pressing gaps in cancer treatment.”
