Safety, Tolerability, and Pharmacokinetics of ASCT-83 in Healthy Adults

NCT07363395 · Status: NOT_YET_RECRUITING · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 72

No results posted yet for this study

Summary

The goal of this clinical trial is to learn if ASCT-83 is safe and well-tolerated and measure how ASCT-83 is absorbed, distributed, and eliminated from the body over time. The study will be conducted in healthy adults.

The main questions this study will answer are:

* Is ASCT-83 safe at clinical doses?
* Does ASCT-83 have side effects at clinical doses?
* How is ASCT-83 absorbed, distributed, and eliminated from the body? Researchers will compare ASCT-83 to a placebo (a look-alike substance that contains no drug).

The study has two parts: participants in Part 1 will receive only one dose of ASCT-83 or placebo participants in Part 2 will receive one dose of ASCT-83 or placebo a day for 7 days. Participants will visit the clinic to take ASCT-83 or placebo, to receive health checkups and undergo health tests. Participants in Part 1 will spend 5 days/4 nights in the clinic, participants in Part 2 will spend 11 days/10 nights in the clinic. In addition, there will be up to 3 outpatient visits.

The results of this study will help determine safe dose levels and support the design of future clinical trials.

Conditions

  • Neuropathic Pain

Interventions

DRUG

ASCT-83

ASCT-83 is a 23-amino acid, macrocyclic peptide with a molecular weight of approximately 3 kilodaltons under development for the treatment of neuropathic pain (NeP). ASCT-83 25 mg/mL sterile solution for injection consists of 25 mg of ASCT-83 drug substance dissolved in 1 mL of histidine buffer. The product also contains mannitol to adjust the osmolarity of the final product. The product is stored at -20°C prior to dilution to achieve the target dose.

DRUG

Placebo

Placebo solution contaninig the same histidine buffer and mannitol concentrations as ASCT-83, with polyoxyl 35 castor oil (0.1% w/v) added to match the appearance of the active solution.
