HRV capsid

Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.

Vapendavir (VPV) is potent virostatic antiviral agent active against all known enterovirus species. VPV binds to the viral capsid, thereby inhibiting viral attachment to the target cell and, independently, preventing release of viral RNA (ribonucleic acid) into the cell. Alt VPV-101 is meant to investigate vapendavir in patients with chronic obstructive pulmonary disease (COPD) who develop a rhinoviral infection. This is a Phase 1, open-label, unblinded study. The primary objective of this study is to characterize single and multiple dose (plus a loading dose) plasma PK profiles of VPV in healthy participants (Group A) and participants with COPD (Group B). Group A is an open-label, 2-sequence, and up to a 3-period, cross-over study to assess the single-dose PK parameters and safety of VPV. Healthy participants may opt to participate in only the first 2 periods, all 3 periods or BID dosing, but it is preferred that participants complete all 3 periods. Group B is an open-label, multi-dose investigation of VPV PK parameters and safety in participants with COPD. Post-dose, follow up will continue for a minimum of 14 days and a maximum of 30 days, depending on which Group the participant is in and which periods said participant completes. There is a target for up to 24 adult participants comprised of healthy participants and participants with COPD.

This is a randomized, single-center, open-label, three-period, six-sequence, crossover, comparative study to evaluate the oral bioavailability of single doses of three vapendavir drug product formulations (the 264 mg free base tablet [test drug], 264 mg free base oral suspension [test drug], and two 132 mg phosphate salt capsules [reference drug]) in healthy volunteers. The study design consists of six dosing sequences. Each sequence comprises 3 periods and each subject is administered one of the three dosing formulations in the first period. A subject receives a different formulation in each of the subsequent periods, so that all subjects receive each formulation. The periods are separated by an approximate 7-day washout.
