- Confirmed diagnosis of high-risk ET.
- Presence of mutCALR.
- Prior treatment with at least 1 cytoreductive therapy.
Exclusion Criteria:
- Presence of any hematologic malignancy other than ET.
- Major bleeding or thrombosis within the last 3 months prior to study enrollment.
- Any prior allogenic or autologous stem-cell transplantation.
- Unresolved toxicity ≥ Grade 2 from previous therapy except for stable chronic toxicities (Grade 2) not expected to resolve, such as stable Grade 2 peripheral neuropathy.
- Prior nonhematologic malignancy except for the following: Malignancy treated with curative intent and with no evidence of active disease for more than 2 years before screening. Adequately treated carcinoma in situ without current evidence of disease.
Other protocol-defined Inclusion/Exclusion Criteria apply.
