Brief Summary:
The clinical study is designed to evaluate the safety, tolerability and pharmacokinetics of inhaled nanoparticle nanoparticle formulation of Remdesivir (GS-5734) alone and in combination with NA-831 in 48 healthy volunteers.
Detailed Description:
It has been discovered that SARS-CoV-2 viruses (Covid-19) can directly invade the nervous system of patients, instead of injuring the nervous system through the immune response. Neurotropism is one common feature of Covid-19. Such neuro-invasive propensity of Covid-19 has been documented almost for all the Beta-coronaviruses including SARS-CoV and MERS-CoV.
Increasing evidence suggests that infection with Sars-CoV-2 causes neurological deficits in a substantial proportion of affected patients. It was observed that patients surviving COVID-19 are at high risk for subsequent development of neurological disease and in particular Alzheimer's disease.
NA-831 is a new neuroprotective and neurogenesis drug that has been demonstrated its promising safety and efficacy in Phase 2A for the treatment of early onset of Alzheimer's disease. NA-831 in oral formulation is well tolerated NA-831 with no adverse effects. NA-831 in oral formulation exhibits predictable pharmacokinetics including dose-dependent exposure linearity and low variability.
Based on animal studies, NA-831 can provide effective interventions during the severe acute respiratory syndrome, and provide appropriate rehabilitation measures afterwards.
Remdesivir (GS-5734) intravenous formulation has been approved by the FDA under the emergency use authorization for potential treatment of severe cases of Covid-19.
It was found the upper respiratory tract is the most prevalent site of SARS-CoV-2 infection early in disease. Delivering drugs directly to the primary site of infection with a nebulizer, inhaled nanoparticle formulation may enable more targeted and accessible administration in non-hospitalized patients and potentially lower systemic exposure to the drug.
The study is designed to evaluate the safety, tolerability and pharmacokinetics of a new nanoparticle formulation of Remdesivir (GS-5734) and combination therapy with NA-831 in healthy volunteers.
