Feb 2021Series CAcuta Capital Partners (lead); Ally Bridge Group (lead); Ample Plus Fund (lead); Avidity Partners (lead); CaaS Capital Management (lead); Lightstone Ventures; Droia Ventures; Novo Holdings; Janus Henderson; Venrock; RA Capital Management; OUP (Osage University Partners)$80MCyteir Therapeutics is a clinical-stage oncology company developing next-generation synthetic lethal therapies for cancer, focusing on DNA damage response biology. Its lead compound, CYT-0851, is an oral inhibitor of RAD51-mediated DNA repair, advancing into phase 2 monotherapy trials in hematologic cancers and solid tumors, as well as combination trials with other cancer therapies. The oversubscribed $80 million Series C financing closed on February 11, 2021, led by RA Capital Management with participation from Janus Henderson Investors, Acuta Capital Partners, Ally Bridge Group, Avidity Partners, Ample Plus Fund, CaaS Capital Management, and existing investors including Novo Holdings, Venrock, Lightstone Ventures, DROIA Ventures, and Osage University Partners. This brought total capital raised to over $140 million to support clinical advancement of CYT-0851 and preclinical research for additional therapies. Post-financing, Cyteir reported approximately $200 million in cash at the end of Q3 2021, funding operations through 2023, with Phase 2 dose identified for CYT-0851 and initiation of monotherapy expansion and Phase 1/2 combination studies underway. By year-end 2021, cash stood at about $190 million, extending runway into 2024. The company went public via IPO on June 18, 2021. Later developments included ongoing clinical trials for CYT-0851 in combinations like capecitabine for platinum-resistant ovarian cancer, but by 2023, Cyteir deferred most R&D, reduced headcount by 70%, and planned a minimal staff of 15 employees by April 2023, retaining focus on CYT-0851 as an MCT inhibitor for solid tumors.
Oct 2019Series BNovo Holdings (lead); Lightstone Ventures; Droia Ventures; Venrock; Celgene; OUP (Osage University Partners)$40MCyteir Therapeutics is a Cambridge-based biotechnology company focused on the discovery and development of novel therapeutics based on DNA repair and synthetic lethality biology for treatment of cancer and autoimmune diseases. The company's lead program targets RAD51 inhibitors, with the goal of entering initial clinical trials in 2019, and it was developing a small-molecule synthetic lethality platform for both oncology and autoimmune indications. In March 2018, Cyteir closed a $29 million Series B financing round led by Venrock, with participation from returning investor Celgene and new investors Lightstone Ventures and DROIA Oncology Ventures. In October 2019, the company secured an additional $40.2 million as part of its Series B financing while simultaneously dosing the first patient in a Phase 1/2 study of its first-in-class RAD51 inhibitor. Board representation was secured by investors including Racquel Bracken from Venrock, Jean George from Lightstone, and Bart Van Hooland from DROIA. The company later went public on Nasdaq under ticker CYT in July 2021, with Novo Holdings emerging as a significant early-stage investor and the largest shareholder at the time of IPO, holding approximately 11.1% of the company.
Mar 2018Series BVenrock (lead); Lightstone Ventures; Droia Ventures; Celgene; OUP (Osage University Partners)$29MCyteir Therapeutics, a Cambridge, MA-based company focused on discovering and developing novel therapeutics based on DNA repair and synthetic lethality for cancer and autoimmune diseases, closed a $29 million Series B preferred stock financing on March 8, 2018. Venrock led the round, with participation from returning investor Celgene and new investors Lightstone Ventures and DROIA Oncology Ventures (also referred to as Droia Ventures). Proceeds from the Series B were allocated to advance the company's lead program on selective small-molecule inhibitors of the RAD51 protein for oncology applications, aiming to enter initial clinical trials in 2019, and to accelerate preclinical development of synthetic lethality therapeutics for autoimmune diseases. The company's drug discovery platform identifies primary cells with tunable genetic constraints, which was used to discover its lead molecules. Cyteir, founded in 2012 as a spinout from the Jackson Laboratory, continued raising capital in subsequent rounds, including a $75.2 million Series B led by Novo in late 2019 with Celgene, Droia Ventures, OUP, Lightstone Ventures, and Venrock, followed by an $80 million Series C in February 2021 led by RA Capital Management with multiple investors including Venrock, Lightstone, and Droia. The company went public in June 2021, raising $133 million by pricing 7.4 million shares at $18 per share on Nasdaq, achieving an initial market cap of approximately $600 million, with proceeds supporting clinical development of lead candidate CYT-0851 and other programs.
Nov 2015Series ACelgene (lead)$6MCyteir Therapeutics, a Cambridge-based biopharmaceutical company spun out from The Jackson Laboratory, closed a Series A financing round totaling $5.5 million on November 5, 2015, with participation from Celgene Corporation and a syndicate of private investors. The company develops targeted therapeutics leveraging discoveries in genomic instability and DNA repair to address cancer and autoimmune disorders. Cyteir holds an exclusive license to key technologies and patents from The Jackson Laboratory. Funds from the Series A will accelerate Cyteir's lead program, enhance its screening platform, and build its drug pipeline. The company was in the research stage at the time, with co-founder Kevin Mills, chief scientific officer, advancing research on molecules that induce cancer cell self-destruction. Donald Corcoran, formerly chief of staff at AstraZeneca, assumed the role of president and CEO concurrent with the financing close.
