Abstract:
Up to 40% of newly diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP) discontinue treatment by 5 years, primarily due to resistance or intolerance. Rates of resistance to second-line (2L) treatment are also high. Some patients with resistance respond with dose escalation of tyrosine kinase inhibitors (TKIs). Asciminib demonstrated safety and efficacy across a broad dosage range. ASC2ESCALATE is an ongoing, Phase II, multicenter, single-arm, dose-escalation study of asciminib in 2L and first-line treatment of CML-CP. The primary end point is major molecular response at 12 months in 2L. Secondary end points include molecular responses at and by scheduled time points, survival, and safety. ASC2ESCALATE is the first study investigating asciminib in CML-CP following failure of one prior TKI.Clinical Trial Registration: NCT05384587 (ClinicalTrials.gov).

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs.
