Summary

Part 1 is a single ascending dose (SAD) trial in healthy volunteers (HV) to assess the safety, tolerability, and pharmacokinetic (PK) profile of orally administered LYT-300. Part 2 is a crossover assessment in HV of the effects of food on the safety, tolerability, and PK profile of orally administered LYT-300. Part 3 is a multiple ascending dose (MAD) trial in HV to assess the safety, tolerability, and PK profile of multiple doses (up to 7 days) of orally administered LYT-300. Part 4 is an assessment of the effects of LYT-300 vs. placebo on pharmacodynamic and patient reported outcome response to a validated clinical model of anxiety.

Detailed description

Part 1: This is a randomized, double-blind, placebo-controlled, SAD design to assess the safety, tolerability, and PK profile of orally administered LYT-300 in HV, in a 3-period, 3-sequence, crossover, dose escalation design. Part 2: This is a randomized, open label, 3-period, 3-sequence, crossover assessment of the effects of food on the PK, safety, and tolerability of orally administered LYT-300 in HV. A single dose of LYT-300 will be administered on 3 occasions, separated by a minimum 7-day washout period. Part 2 is planned as a single dosing cohort. Part 3: This is a randomized, double-blind, placebo-controlled, sequential, MAD trial in HV to assess the safety, tolerability, and PK profile of multiple doses (up to 7 days) of orally administered LYT-300. This part will include ascending doses given either once daily in the morning (QAM), once daily in the evening (QHS), or twice daily (BID). Part 4: This is a double-blind, randomized assessment of the effects in HV of a single dose of LYT-300 vs. placebo on pharmacodynamic and patient reported outcome response to a validated clinical model of anxiety.
