Material Changes and Clinical Data
The Company announced updated safety and efficacy data for NX-5948, an oral agent targeting BTK and BCL2. Key findings include:
- Safety Profile: Data covers 79 patients in the Phase 1a dose escalation study (doses 50 mg to 600 mg). The drug was well tolerated. Most common treatment-emergent adverse events were purpura/contusion, thrombocytopenia, and neutropenia.
- Efficacy in CLL: Among 26 efficacy-evaluable patients with relapsed or refractory chronic lymphocytic leukemia (CLL), the objective response rate (ORR) was 69.2% across all doses.
- Response Characteristics: Responses were observed as early as 8 weeks, with many patients showing deepening responses over time. All responses were ongoing as of the April 17, 2024 data cutoff.
- Patient Population: The CLL cohort was heavily pretreated, with a median of four prior lines of therapy. High rates of prior exposure to covalent BTK inhibitors (96.8%) and BCL2 inhibitors (90.3%) were noted.
- Resistance Markers: Responses were observed despite baseline mutations associated with BTK inhibitor resistance, including BTK mutations (43.3%) and PLC2G mutations (20.0%). Poor prognostic features like TP53 mutations were present in 46.7% of patients.
