Divesiran demonstrates significant clinical responses in the phase 2 SANRECO trial for polycythemia vera, with 88% of patients achieving a response compared to 19% with placebo. Silence Therapeutics plans to advance to a phase 3 trial to further evaluate this first-in-class siRNA therapy.

Divesiran, a first-in-class small interfering RNA (siRNA) therapy, met the primary end point of the phase 2 SANRECO trial (NCT05499013) in patients with polycythemia vera (PV), according to a news release from Silence Therapeutics.¹ Silence Therapeutics announces positive topline results from phase 2 SANRECO trial of divesiran in polycythemia vera, supporting its potential best-in-class profile.

The company plans to initiate a phase 3 trial evaluating divesiran vs placebo in the first half of 2027. “Across the SANRECO phase 1/2 program, divesiran has been well tolerated and has consistently delivered durable hematocrit control in patients [dependent on phlebotomy] with PV, regardless of risk level or disease severity,” said Marina Kremyanskaya, MD, PhD, associate professor of medicine, hematology and medical oncology, at the Icahn School of Medicine at Mount Sinai, in the press release.¹ “These compelling results highlight divesiran’s potential to transform PV management with convenient, infrequent dosing that reliably controls hematocrit and addresses longstanding unmet needs for patients.” The trial assessed divesiran at 6 mg/kg administered subcutaneously every 6 weeks or every 12 weeks in patients with uncontrolled hematocrit who remained phlebotomy dependent despite standard-of-care treatment, which could include hydroxyurea, interferon, and/or ruxolitinib (Jakafi).2 All patients have completed the placebo-controlled portion of the trial and are now in the 3-year double-blind and open-label extension periods.
