  • Ryvu PRMT5 inhibitors show potential best-in-class profiles, including a strong antiproliferative effect on MTAP-deleted cell lines and a good safety window versus MTAP WT cells.
  • Ryvu’s WRN inhibitor program has demonstrated target engagement and selective potency with a synthetic lethal effect; in vivo efficacy studies exhibited pronounced tumor growth inhibition in an MSI-H colorectal cancer xenograft model.
  • Ryvu’s proprietary ONCO Prime discovery platform, which recently received a PLN 26 million (approx. USD 6.6 million) grant from the Polish Agency for Enterprise Development, has identified novel drug targets in KRAS-mutant patient-derived cells (PDCs) with therapeutic potential in colorectal cancer; the ONCO Prime platform has broad potential across multiple tumor types.
  • RVU120 shows efficacy both as a monotherapy and synergistically in combination with ruxolitinib in preclinical models of myeloproliferative neoplasms, including myelofibrosis and polycythemia vera.
  • MEN1703 (SEL24), presented by partner Menarini Group, shows cytotoxic activity in myelofibrosis cell lines as a monotherapy and synergistically in combination with ruxolitinib.

KRAKOW, Poland, April 10, 2024 /PRNewswire/ — Ryvu Therapeutics (WSE: RVU), a clinical-stage drug discovery and development company focusing on novel small molecule therapies that address emerging targets in oncology, presents preclinical data from its synthetic lethality pipeline, RVU120, and MEN1703 (SEL24) at the 2024 AACR Annual Meeting, April 5-10 in San Diego, California.

Disease Progression for Patients With Low-Risk Myelofibrosis Participating in the MOST Study

A group of researchers presented data on disease progression for patients with low-risk myelofibrosis (MF) participating in the prospective observational Myelofibrosis and Essential Thrombocythemia Observational Study (MOST) at the 2023 ASH Annual Meeting & Exposition.

In order to qualify for the MOST study, participants were required to have a physician-reported diagnosis of MF (primary myelofibrosis [PMF], post progression of polycythemia vera [post-PV], or post essential thrombocythemia [post-ET). They also could not have any risk factors per the Dynamic International Prognostic Scoring System (DIPSS) criteria. However, participants could be aged 65 years or older. The number of patients with MF enrolled in the study was 232. Of this population, 205 met the study criteria and were included in cohort A. Although the remaining 27 patients had  ≥1 DIPSS risk factor, they were included in the study in a separate cohort B.

For the study, disease progression was defined by the worsening of clinical or laboratory parameters, which included one or more of the following criteria: hemoglobin (Hb) <10 g/dL, platelets <100×109/L, presence of constitutional symptoms (weight loss, fever, or sweats), new or worsening splenomegaly, blasts >1%, white blood cell count >25×109/L, death due to disease progression, leukemic transformation (LT), or >1 red blood cell transfusion. The median follow-up was 52.9 months (42-68).

Next-Generation JAK Inhibitors Signal the Future of Myelofibrosis Treatment Advances

Posted on by

Ashling Wahner

Newer-generation JAK inhibitors are increasingly adept at controlling symptoms in patients with myelofibrosis and may recapture treatment response in patients who have progressed on prior ruxolitinib (Jakafi), according to Joseph G. Jurcic, MD.

“Using drugs that target all these particular abnormalities can result in symptom and spleen improvement, and in some, a reduction in cytokines and allelic burden,” Jurcic said in an interview with OncLive®.

In the interview, Jurcic discussed the benefits and limitations of several JAK inhibitors for patients with myelofibrosis, highlighting the treatment advances that have been made since the introduction of ruxolitinib to the treatment paradigm, considerations for the use of fedratinib (Inrebic), and the potential advantages of pacritinib (Vonjo) for patients with anemia.
