Key Inclusion and Exclusion Criteria
Inclusion Criteria
- Documented lymphoid or myeloid neoplasm with 8p11 rearrangement known to lead to FGFR1 activation, based on standard diagnostic cytogenetic evaluation performed locally, before signing informed consent for this study.
- Eligible subjects must:
Exclusion Criteria
- Prior receipt of a selective FGFR inhibitor.

Protocol Summary
The proportion of participants who achieve Complete Response (CR) based on response criteria for myeloid/lymphoid neoplasms with FGFR1 rearrangement
Timeframe: : Assessed at protocol-defined timepoints through end of study, up to approximately 24 months.
The proportion of subjects who achieve response, defined as a best response of CR or PR, as determined by investigator assessment according to the response criteria
Timeframe: Assessed at protocol-defined timepoints through end of study, up to approximately 24 months.
The proportion of subjects who achieve a complete cytogenetic response (CCyR) as assessed by local analysis and investigator evaluation
Timeframe: Assessed at protocol-defined timepoints through end of study, up to approximately 24 months.
The proportion of subjects who achieve a partial cytogenetic response (PCyR) as assessed by local analysis and investigator evaluation
Timeframe: Assessed at protocol-defined timepoints through end of study, up to approximately 24 months.
Duration of CR, defined as the time from first assessment of CR to the earlier of disease progression or death due to any cause
Timeframe: Assessed at protocol-defined timepoints through end of study, up to approximately 24 months.
Duration of response, defined as the time from first assessment of CR or PR to the earlier of disease progression or death due to any cause
Timeframe: Assessed at protocol-defined timepoints through end of study, up to approximately 24 months.
Progression-free survival (PFS)
Timeframe: From the date of first study drug dose until the date of disease progression or until death due to any cause, whichever is earlier, assessed up to approximately 24 months.
Overall survival
Timeframe: From date of first study drug dose until death due to any cause, assessed up to approximately 24 months.
Safety and tolerability as assessed by frequency, duration, and severity of adverse events
Timeframe: From baseline through 30-35 days after end of treatment, up to 7 months per individual subject
