ZE74-0282 is designed to selectively inhibit the JAK2 V617F mutation while sparing wild-type JAK2, addressing one of the key limitations of currently approved JAK inhibitors, which suppress both mutant and normal hematopoietic signaling. Preclinical studies demonstrated up to 500-fold selectivity for mutant JAK2 over wild-type JAK2 and potent inhibition of STAT5 phosphorylation in JAK2 V617F-mutant cells, suggesting the potential for improved efficacy with reduced hematologic toxicity.
In preclinical whole-blood assays using samples from patients with JAK2 V617F-positive myelofibrosis, ZE74-0282 preferentially inhibited malignant myeloid cells while largely sparing non-mutant cells. The compound also showed greater suppression of mutant colony formation and stronger antitumor activity than fedratinib in xenograft models, supporting its potential to modify disease biology rather than providing only symptomatic control.
Eilean Therapeutics advanced ZE74-0282 into first-in-human clinical development after completing a comprehensive nonclinical package demonstrating favorable pharmacology, safety, pharmacokinetics, and oral bioavailability. In addition to the healthy volunteer study, a Phase I dose-escalation and expansion trial has begun enrolling approximately 60 patients with JAK2 V617F-positive hematologic malignancies, including PV and MF, with study completion expected in 2028. Progress into clinical testing represents a significant milestone toward commercialization.
The JAK2 V617F mutation is the predominant driver mutation in polycythemia vera and is also present in a substantial proportion of essential thrombocythemia and primary myelofibrosis patients. A therapy capable of selectively targeting this mutation could potentially be developed across several MPN indications, substantially expanding the commercial opportunity beyond a single disease.
ZE74-0282 is being developed as a once-daily oral small molecule, an administration route that is well suited for chronic management of MPNs. Combined with its mutant-selective mechanism, oral dosing could support long-term adherence and facilitate use in both earlier- and later-line treatment settings if clinical efficacy and safety are confirmed.
ZE 74-0282 Recent Developments
In December 2025, Eilean Therapeutics announced the advancement of ZE74-0282 into first-in-human clinical development. ZE74-0282 is a novel, highly selective inhibitor of the mutated Janus kinase 2 (JAK2) V617F variant and is being developed as a differentiated therapeutic candidate for myeloproliferative neoplasms, including myelofibrosis.

ZE 74-0282 Drug Summary
ZE 74-0282 is an investigational small-molecule therapeutic being developed by Zentiva for the treatment of polycythemia vera (PV). Although detailed information regarding its molecular target and mechanism of action has not been publicly disclosed, the compound is being evaluated as a potential oral therapy aimed at controlling the excessive production of blood cells that characterizes PV, with the goal of maintaining hematocrit within target levels, reducing the need for therapeutic phlebotomy, and lowering the risk of thrombotic complications. ZE 74-0282 is currently in the early stages of clinical development, where its safety, pharmacokinetics, tolerability, and preliminary efficacy are being assessed in patients with PV. As an investigational candidate, publicly available clinical and mechanistic data remain limited, and its future role in the treatment landscape will depend on the outcomes of ongoing and subsequent clinical studies demonstrating meaningful efficacy, safety, and differentiation from established therapies such as JAK inhibitors and interferon-based treatments. The report provides ZE 74-0282's sales, growth barriers and drivers, post usage and approvals in multiple indications.
