- Conditions
- chronic-phase chronic myeloid leukemia
- Registration Number
- JPRN-jRCTs071180047
- Lead Sponsor
- Kimura Shinya
- Brief Summary
The DAVLEC study showed that the treatment strategy of increasing or decreasing the dasatinib dose from a starting dose of 20 mg per day while monitoring therapeutic effects and AEs was efficacious and well-tolerated in elderly patients with CML-CP.
