About

This multicenter, randomized, double-blind, parallel-group, placebo-controlled pilot study evaluated the safety, tolerability, and exploratory efficacy of orally administered NUV001 in adult participants with sickle cell disease (HbSS or HbSβ0 genotypes). A total of 168 participants were randomized in a 1:1:1 ratio to receive NUV001 immediate-release (IR), NUV001 gastro-resistant (GR), or placebo, in addition to standard of care, for 90 days over 5 study visits. The primary objective was to assess safety and tolerability based on adverse events, clinical laboratory safety parameters, and vital signs. Exploratory secondary objectives evaluated hematologic, hemolysis, and patient-reported outcomes.

Full description

This was a multicenter, randomized, double-blind, parallel-group, placebo-controlled pilot study conducted in adult participants with sickle cell disease.

Participants were randomized in a 1:1:1 ratio to one of three treatment groups:

1. NUV001 immediate-release (IR)
2. NUV001 gastro-resistant (GR)
3. Matching placebo

All treatments were administered orally in addition to standard of care for 90 days.

The study was designed to evaluate safety and tolerability, including adverse events, clinical laboratory safety parameters, and vital signs. Exploratory objectives included evaluation of hematologic parameters, markers of hemolysis, and patient-reported outcomes related to pain and quality of life.

The study was conducted as a pilot, feasibility, and design-informing clinical study.
