Bavituximab targets exposed phosphatidylserine (PS) in the tumor microenvironment, resulting in repolarization of myeloid suppressor cells/M2 macrophages to M1, production of pro-inflammatory cytokines such as IFN? and IL-12, dendritic cell maturation, and tumor specific cytotoxic T-cell activation. SUNRISE was a Phase III trial of docetaxel with bavituximab (D+B) or placebo (D+P) in patients with treated Stage IIIb/IV non-squamous NSCLC. Recent correlative analyses from SUNRISE suggest bavituximab is more active in PD-L1 negative, immune cold tumors and thus may complement PD-1/PD-L1 ICI.
Method:
This subgroup analysis included all patients who received subsequent ICI after discontinuing SUNRISE study drug. We calculated overall survival (OS) both from randomization and start of subsequent ICI.
Result:
Ninety-three of 597 randomized patients (16%) received ICI as next line of therapy after SUNRISE assigned treatment. Baseline characteristics were balanced between the treatment groups and consistent with the ITT population. From randomization, mOS was not reached (95% confidence interval [CI], 15.2-NA) in D+B (N=46) and 12.6 months (95% CI, 10.4-17.8) in D+P (N=47) (hazard ratio [HR], 0.46; P=0.006) (Figure). From start of ICI, mOS was not reached (95% CI, 10.2-NA) in D+B and 6.2 months (95% CI, 3.9-8.7) in D+P (HR, 0.42; P=0.002). The mPFS was 6.0 months (95% CI, 3.5-6.5) in D+B and 4.4 months (95% CI, 2.6-6.3) in D+P (HR, 1.00; P=0.991). ORR was 20% vs. 13% (Odds ratio 0.6; P=0.41) for D+B and D+P, respectively. The safety profile was similar between groups and no immune related (IR) toxicities (colitis, pneumonitis, hypothyroidism) were reported.
Conclusion:
Within the limits of a subgroup analysis, a significant improvement in OS was observed for patients previously treated with D+B. Furthermore, bavituximab has not been associated with IR toxicities and might serve as a useful drug in combination with ICI for the treatment of immune cold tumors. Figure 1
