Study To Assess Safety, Tolerability And PK Of ATB-346 In Healthy Subjects

A Double-Blind, Placebo-Controlled, Phase I Study To Assess Safety, Tolerability And Pharmacokinetics Of Single/Multiple Ascending Doses Of ATB-346 Orally Administrated In Healthy Male And Female Subjects

A double-blind, placebo-controlled, phase I study to assess safety, tolerability and pharmacokinetics of single/multiple ascending doses of atb-346 orally administered in healthy male and female subjects.

Study Overview

• Status: Completed
• Conditions: Chronic Pain
• Intervention / Treatment: Drug: Placebo; Drug: ATB-346

Detailed Description

Single ascending doses of ATB-346 given to multiple cohorts followed by multiple ascending doses of ATB-346 given to multiple cohorts in order to assess its safety, tolerability, and pharmacokinetics. A single dose cohort was also conducted to assess the effect of food on the drug's characteristics.

8. Willingness to adhere to the protocol requirements as evidenced by the informed consent form (ICF) duly read, signed and dated by the volunteer

9. A female volunteer must meet one of the following criteria:

   • If of childbearing potential - agrees to use one of the accepted contraceptive regimens from at least 28 days prior to the first drug administration, during the study and for at least 60 days after the last dose. An acceptable method of contraception includes one of the following:

10. A male volunteer with sexual partners who are pregnant, possibly pregnant, or who could become pregnant must meet the following criterion:

    • Participant is inapt to procreate, defined as surgically sterile (i.e. has undergone a vasectomy, it must be at least 6 months since the surgery)

    • Participant agrees to use of the accepted contraceptive regimens from first drug administration until 3 months after the last drug administration. An acceptable method of contraception includes one of the following:
