	SARS-CoV-2 neutralizing antibody program update
	Interim results from the BLAZE-1 outpatient RCT showing improvements in viral load, symptoms and hospitalization. Combination therapy significantly reduced viral load at day 11 (p=0.011). A greater effect is seen at day 7 (p<0.001). The proportion of patients with persistent high viral load at day 7 for combination therapy was lower (3.0 percent) versus placebo (20.8 percent), corresponding to a nominal p value of p<0.0001 without multiplicity adjustment. No emergent putative resistance variants have been observed thus far in patients treated with combination therapy. The rate of COVID-related hospitalization and ER visits was lower for patients treated with combination therapy (0.9 percent) versus placebo (5.8 percent), a relative risk reduction of 84.5 percent (p=0.049). This was also similar to observations for LY-CoV555 monotherapy. Combination therapy has been generally well tolerated with no drug-related serious adverse events. In LY-CoV555 monotherapy studies there have been isolated drug-related infusion reactions or hypersensitivity that were generally mild (two reported as serious infusion reactions, all patients recovered). NCT04427501 risk of hospitalization or ER visit, 84.5% lower, RR 0.15, p = 0.05, treatment 112, control 156.

Please send us corrections, updates, or comments. Vaccines and treatments are both extremely valuable and complementary. All practical, effective, and safe means should be used. Elimination of COVID-19 is a race against viral evolution. No treatment, vaccine, or intervention is 100% available and effective for all current and future variants. Denying the efficacy of any method increases the risk of COVID-19 becoming endemic; and increases mortality, morbidity, and collateral damage. We do not provide medical advice. Before taking any medication, consult a qualified physician who can provide personalized advice and details of risks and benefits based on your medical history and situation. Treatment protocols for physicians are available from the FLCCC.
