Divesiran Market Summary

Key Factors Driving Divesiran Growth

1. First-in-class siRNA therapy targeting TMPRSS6 with a differentiated mechanism:

Divesiran is an investigational small interfering RNA (siRNA) therapy that silences TMPRSS6, increasing endogenous hepcidin levels and restricting iron availability for erythropoiesis. This approach directly reduces excessive red blood cell production in PV and differs fundamentally from currently available cytoreductive agents or interferons. Its novel mechanism positions divesiran as a potentially disease-modifying therapy for patients who remain dependent on therapeutic phlebotomy.

2. Promising Phase I efficacy with durable reduction in phlebotomy burden:

Data from the Phase I SANRECO study demonstrated durable hematocrit control (<45%) and a substantial reduction in therapeutic phlebotomy requirements in phlebotomy-dependent PV patients. Follow-up analyses presented at the 2026 European Hematology Association (EHA) meeting showed that during the 16-week period after the final dose, only four phlebotomies were required, while among 14 patients with extended follow-up, the median time to first phlebotomy was 287 days. Improvements in PV-related symptom scores and quality of life were also reported, supporting long-lasting clinical benefit.

3. Convenient infrequent dosing could improve long-term adherence:

The ongoing Phase II SANRECO trial is evaluating every-6-week (Q6W) and every-12-week (Q12W) subcutaneous dosing regimens. The prolonged pharmacodynamic activity observed in Phase I supports the feasibility of infrequent dosing, which could offer a significant advantage over therapies requiring more frequent administration or repeated phlebotomies, thereby improving patient convenience and treatment adherence.

4. Rapid clinical development with important near-term catalysts:

Silence Therapeutics completed enrollment in the randomized Phase II SANRECO trial ahead of schedule, reflecting strong investigator and patient interest. The study enrolled 48 phlebotomy-dependent PV patients, with the primary endpoint evaluating maintenance of hematocrit below 45% without phlebotomy between Weeks 18 and 36. The company expects topline Phase II results in August 2026, making this one of the most significant near-term value inflection points for the program.

Divesiran Recent Developments

In October 2025, Silence Therapeutics announced it had completed patient enrollment in the SANRECO Phase II study of Divesiran, a first-in-class siRNA targeting TMPRSS6, for the treatment of polycythemia vera (PV). Initial topline results from the SANRECO Phase II study are anticipated in the third quarter of 2026.

Divesiran Drug Summary

Divesiran is an investigational, first-in-class small interfering RNA (siRNA) therapeutic developed by Silence Therapeutics for the treatment of polycythemia vera (PV). Administered as a subcutaneous injection, divesiran is designed to silence the TMPRSS6 gene in the liver, thereby increasing endogenous hepcidin production, the body's key regulator of iron metabolism. Elevated hepcidin restricts iron availability to the bone marrow, reducing the excessive iron-dependent production of red blood cells that characterizes polycythemia vera and helping maintain hematocrit control while reducing the need for therapeutic phlebotomy. The therapy has demonstrated promising pharmacodynamic activity and favorable safety in early clinical studies, with durable reductions in phlebotomy requirements and improvements in disease-related symptoms, and is currently being evaluated in Phase II clinical trials for PV. Divesiran has also received both FDA Fast Track and Orphan Drug designations for polycythemia vera, highlighting its potential as a novel disease-modifying treatment for this rare hematologic malignancy.
