Old HIV drug could help bone marrow make red blood cells
NCT ID NCT07281781
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether nelfinavir, a drug originally used for HIV, can help people with myelofibrosis who have anemia (low red blood cells). The drug aims to restore iron delivery to the bone marrow. Ten adults with myelofibrosis and low hemoglobin will take nelfinavir twice daily to see if their anemia improves and if fibrosis markers decrease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Nelfinavir (an HIV drug being repurposed)
- What this could lead to
- If it works, this could offer a new way to treat anemia in myelofibrosis patients without needing blood transfusions.
- What could go wrong
- This is a very small early-phase trial with only 10 participants, so results may not apply broadly. The drug may not improve anemia or could cause side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * ≥18 years of age * Have a diagnosis of myelofibrosis (MF) according to the 2016 WHO criteria * Has a hemoglobin ≤ 10gm/dL at screening * Serum ferritin ≥ 100 * May continue on current MPN treatment, including aspirin, hydroxyurea, interferon-alpha, ruxolitinib, fedratinib, or anagrelide. * Peripheral blast count \<10% during Screening. * Free of other known active or metastatic malignancies other than localized skin cancer. * Amenable to blood draws and symptom assessments. * Agree to the use of contraceptives. Female subjects of childbearing potential and their male partners, or male subjects who have female partners of childbearing potential, should both use an effective contraception method during the study and continue to use contraception for 60 days after the last dose of study drug. Exclusion Criteria: * Eastern Cooperative Oncology Group (ECOG) questionnaire score of ≥3 * Currently pregnant or planning on being pregnant within the study period. * Currently taking Momelotinib or Pacritinib (these agents are purported to reduce hepcidin). * Currently taking any of the contraindicated medications to Nelfinavir listed in section 13.2 * Currently breastfeeding. * Known uncontrolled active viral or bacterial infection. * Known HIV+ * Significant impairment of major organ or hematopoietic function defined as 1. Serum creatinine clearance less than 30 ml/min (eGFR). 2. Bilirubin more than 1.5 mg/dl except for Gilbert's disease. ALT or AST more than 2X upper normal limit or has radiologic evidence of liver cirrhosis. 3. Platelets \< 50 × 10\^9/L without transfusions 4. ANC \< 0.75 × 10\^9/L without growth factors * Known history of allergic reaction to nelfinavir.
