TRANSCRIPT
My Mask Protects Us Both
• CDC published updated analysis regarding the role of mask use in protecting the wearer. The official CDC guidance continues to emphasize the value of masks as source control by filtering and slowing forward momentum of particles not captured
• Updated analysis indicates that masks can provide protection for wearer as well, including ability to o Filter 50-70% of fine droplets and particles less than 10 microns
• Filtration effect varied between masks and mask types, with multi-layer masks constructed with more densely woven material performing better than single-layer masks made from lower thread count fabrico Studies evaluated various mask materials
• Synthetic (eg, polypropylene which generate ‘triboelectric’ charge)• Natural materials (eg, silk which repel most droplets)
ADA Reasonable Modifications
• Wearing masks is important, but not everyone can wear one safely
o Medical, mental health, or developmental disabilities
• Mask mandates do not not override consideration of reasonable modifications required by Americans with Disabilities Act (ADA)o The ADA reasonable modification of practices and procedures
requirement remains applicable to healthcare providers
• Individuals are not required to disclose their disabilityo “Requiring proof of a disability would amount to discrimination or
exclusion from having equal access to routine goods and services” ("Face Coverings and the ADA")
• ADA does not provide protection for people without disabilities

Nov 10, 2020: Monoclonal Ab EUA
• LY-CoV555 (bamlanivimab; Eli Lilly) received EUA for one-time 700 mg IV treatment of outpatients
• In Phase 2 study, 700mg dose did not result in a decline in viral load in outpatients over 11 dayso 2,800 mg dose resulted in ~3 fold reduction in viral load
o Any antibody dose had lower symptom severity as well as lower hospitalization rates and ED visits (1.7%) than placebo (6%)
o Additional unpublished data re 700mg dose?
EUA Guidance for Bamlanivimab
1. >12 years
2. >40kg (88 pounds)
3. Test positive for SARS-CoV-2
4. Currently experiencing mild or moderate COVID-19 disease, but not currently hospitalizedo Should not be administered to individuals who are
receiving supplemental oxygen therapy (ie, high-flow oxygen or mechanical ventilation), as this could increase the risk of “worse clinical outcomes.”; AND
5. High risk for severe COVID-19 disease
Bamlanivimab Availability
• Biomedical Advanced Research and Development Authority (BARDA) pre-purchased 300k doses from Eli Lilly, as part of OWSo US$375 million, with option of 650k more doses through end
of 2021 at an additional cost of US$812.5 milliono 100 vials coming to NH
• Availability for outpatient infusion centers and hospitals
• NH Medicaid and Medicare (presumably private insurers) will likely pay for infusion costs and Bamlanivimab at no patient cost share for covered personso Drug cost only be reimbursed if the healthcare providers had
to purchase product
Phase 3 in Hospitalized Patients Halted
• NIH announcement halted RDV+Ly-CoV555 trial because DSMB reviewed data on 326 patients on Oct 26th and concluded there was a “low likelihood that the intervention would be of clinical value” for hospitalized patientso Note 7g of Ly-CoV555—10 times dose in FDA EUA
application for less ill outpatients
• So possible benefit among outpatients, but longer course of infection and severity among hospitalized patients reduces likelihood of benefit for the treatment
BLAZE-1: Combination mAbs in Outpts
• RCT Phase 2 study of LY-CoV555 (bamlanivimab) + LY-CoV016 (etesevimab)o Both neutralizing monoclonal antibodies against spike
protein
• In mild-to-moderate recently diagnosed outpatientso 112 treated, 156 placebo
o 2,800 mg of each antibody together
o 5.6 fold suppression of viral load at day 11 compared to placebo
o Hospitalization and ED visits was lower for patients treated with combination therapy (0.9%) versus a placebo (5.8%)
