- The company reported significant advances in both evorpacept and ALX2004 clinical programs, with evorpacept showing strong efficacy in patients with high CD47 expression.
- ALX Oncology Holdings Inc (ALXO) has a robust cash balance of $67 million, expected to provide runway into the first quarter of 2027.
- The company is on track to dose the first patient in its Phase II breast cancer trial this quarter, targeting CD47 and HER2 biomarker-driven strategies.
- ALX2004, a novel EGFR-targeted ADC, is progressing well in clinical trials, with patients currently being enrolled in the second dose cohort.
- The conventional approach to CD47 targeting has caused significant toxicities in some patients, highlighting potential safety concerns.
- The company faces challenges in developing a companion diagnostic for CD47 expression, which is crucial for patient selection in trials.
