Data presented at the 67th ASH Annual Congress (6 – 9 December 2025) in Orlando (USA) from the ongoing HIBISCUS KIDS study showed that:
- In cohort 1, 15 adolescent participants (10 female, 10 Black/African American, 13 HbSS and 2 HbSβ 0 – thalassemia genotype) with a mean age of 14.5 years (range 12–17) received etavopivat 400 mg/day orally for 24 weeks.
- All participants completed 24 weeks of treatment.
- Most adverse events (101/105 events) were mild or moderate in severity. The most common adverse events were sickle cell anemia with crisis (9/15), malaria (4/15), headache (4/15), and tonsillitis (4/15).
- 10/15 participants had an Hb response, with a mean change in Hb from baseline of 1.4 g/dL at week 24.
- The mean number of VOCs over 24 weeks was 1.8
- Cohort 1 enrollment (total 25 patients) and dosing are complete; weight-based dosing with a granule formulation has begun for cohort 2, children aged 6–12 years.

Data presented at the 66th ASH Annual Congress (7 – 10 December 2024) in San Diego (USA) showed that:
-
- 60 patients were randomised in the phase 2 part of the trial to receive 200mg (21 patients), 400mg (20 patients), and placebo (19 patients) of etavopivat.
- Hb response was seen early by Week 2 and maintained over 52 weeks.
- The interim data presented showed that etavopivat reduced the annual VOC rate, increased Hb levels, improved haemolysis, and patient-reported fatigue.
