Summary

This early-stage trial tests an injectable drug called GL-2045 in 42 adults with immune thrombocytopenia (ITP), a condition where the immune system destroys platelets, raising bleeding risk. The goal is to see if GL-2045 can safely raise platelet counts like standard IVIg therapy but with fewer side effects. Participants receive repeated doses at different levels to find the best balance of safety and effect.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
GL-2045
What this could lead to
If successful, this could offer a new treatment option for immune thrombocytopenia that works like IVIg but may be easier to take and have fewer side effects.
What could go wrong
This is an early Phase 1 trial with only 42 participants, so safety and effectiveness are not yet proven. The drug may not work as hoped or could cause unexpected side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: 1. Male or female between 18 and 80 years of age with ITP or certain limited ITP conditions. 2. Females must not be pregnant or lactating. Males and females of childbearing potential must agree to use contraception. 3. A platelet count of 10 to 49 × 10\^9/L at baseline. 4. Study subjects must have prior response to corticosteroids or to intravenous immunoglobin (IVIg) documented by a consultant hematologist. Prior response to thrombopoietin receptor agonists is insufficient for eligibility. 5. The subject may be on a stable dose of corticosteroids for the 3 months prior to study entry, limited to a daily dose of prednisone 10 mg or equivalent. No reductions or increases of steroids are allowed during the study. Key Exclusion Criteria: 1. Any serious adverse event (SAE) with prior IVIg dosing. 2. Prior splenectomy within 1 year of randomization or planned splenectomy during the study period. 3. Participants with grade 2 bleeding by World Health Organization (WHO) bleeding criteria in the 8 weeks prior to treatment. 4. Abnormal organ function including liver and kidney. 5. Any previous or current treatments prohibited by the protocol. 6. Treatment within the last 4 weeks or intention to treat during the study with a thrombopoietin receptor agonist including romiplostim (Nplate®), eltrombopag (Revolade®), or avatrombopag (Doptelet®).
