While bevacizumab might help extend overall survival by a few months, the quality of life is not improved much. Bevacizumab (Avastin) has a horrible safety profile. Because many of the trials, Avastin was used in, were too small to power statistical significance, here is a paper that pooled several trials to show that it had statistical significance in OAS and PFS. This paper is from 2013.

The analysis population comprised 3,763 patients (1,773 chemotherapy with or without placebo; 1,990 chemotherapy plus bevacizumab). The addition of bevacizumab to chemotherapy was associated with statistically significant increases in overall survival (OS; HR, 0.80; 95% CI, 0.71–0.90) and progression-free survival (PFS; HR, 0.57; 95% CI, 0.46–0.71). The effects on OS and PFS across subgroups defined by chemotherapy backbone (oxaliplatin-based, irinotecan-based), extent of disease (liver metastases only, extensive disease), age (<65, ≥65 years), Eastern Cooperative Oncology Group performance status (0, ≥1), and KRAS status (wild-type, mutant) were consistent with the overall analysis. Incidence rates of grade ≥3 hypertension, proteinuria, bleeding, wound-healing complications, gastrointestinal perforations, and thromboembolic events were increased with bevacizumab treatment.
Leronlimab should improve the patient's quality of life and extend their OAS and PFS much better than Avastin. I wonder if the down-regulation of VEGF, from Leronlimab, can be measured against what bevacizumab does? If I had the death sentence of mCRC, I would not want Avastin (bevacizumab) as part of my treatment. It just looks like a horrible way to die!
