What is the purpose of this trial?

This trial tests a new oral medication, IMG-7289, for individuals with essential thrombocythemia, a condition where the body produces too many platelets, raising the risk of blood clots. The trial aims to determine if IMG-7289 can safely and effectively reduce platelet counts in patients who have not responded to or cannot tolerate the usual treatment, hydroxyurea. Suitable candidates have been diagnosed with essential thrombocythemia and require treatment to lower platelet levels, particularly if hydroxyurea has been ineffective or caused adverse side effects. Participants must be able to swallow capsules and will undergo tests such as spleen size checks and blood sampling. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Do I have to stop taking my current medications for the trial?

Yes, you must stop taking your current Essential Thrombocythemia (ET) therapy at least 2 weeks before starting the study drug, or 4 weeks if you are on interferon.

Is there any evidence suggesting that IMG-7289 is likely to be safe for humans?

Research has shown that IMG-7289 is generally safe for people with essential thrombocythemia. In one study, 24 patients experienced serious side effects, but only 4 of these were linked to the treatment. This indicates that most patients tolerate the treatment well. Additionally, IMG-7289 has improved platelet and white blood cell counts without causing major side effects. While some patients might encounter issues, the overall evidence supports the safety of IMG-7289 for essential thrombocythemia. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

IMG-7289 is unique because it works differently from most current treatments for essential thrombocythemia, like hydroxyurea or anagrelide, which primarily focus on reducing platelet production. IMG-7289 targets a specific enzyme called LSD1 (lysine-specific demethylase 1), which plays a role in the regulation of blood cell production. Researchers are excited about this treatment because by targeting LSD1, IMG-7289 may offer a more targeted approach with potentially fewer side effects, improving the quality of life for patients.

What evidence suggests that IMG-7289 might be an effective treatment for essential thrombocythemia?

Research has shown that IMG-7289, also known as bomedemstat, may help treat essential thrombocythemia (ET). Studies have found that this treatment stabilizes blood cell levels in people with ET. Bomedemstat lowers platelet counts and improves symptoms without causing major side effects. It also controls white blood cell levels and reduces genetic changes linked to the condition. Overall, the treatment effectively manages symptoms and improves blood cell levels for those with ET. ^{2 3 4 6 7}

Are You a Good Fit for This Trial?

Adults diagnosed with Essential Thrombocythemia who have high platelet counts despite hydroxyurea treatment, can swallow capsules, and will use contraception. Excluded are those with unresolved toxicities from past treatments, active infections including HIV/hepatitis, bleeding risks, pregnancy/breastfeeding plans within six months or current breastfeeding.

Inclusion Criteria

I can swallow pills.
