Details and patient eligibility

About

The purpose of this study is to assess the safety and tolerability of an oral solution of CDX-6114 when administered as a single dose in healthy volunteers.

Full description

This is a Phase 1, double-blind, placebo-controlled study in approximately 32 healthy volunteers who are 18 to 55 years old. Four cohorts are planned, each consisting of 8 subjects; the cohorts as planned are 0.225, 0.75, 2.25, and 7.5 g in oral solution. Increasing doses of CDX-6114 will be assessed sequentially until the final dose is evaluated or any of the stopping criteria are reached. Subjects will each receive a single dose and then will be followed for a total of 22 days (3 weeks).

3. These requirements do not apply to participants in a same sex relationship.
Male subjects must agree not to donate sperm starting at screening and continuing throughout the clinical study period, and for 90 days after study drug administration.

1. Must agree not to become pregnant during the clinical study period and for 30 days after study drug administration.
2. Must have a negative serum pregnancy test at screening.
3. If heterosexually active, must agree to consistently use a form of highly effective birth control, in combination with a barrier method starting at screening and continuing throughout the clinical study period, and for 30 days after study drug administration
  
  Or
4. Must agree to stay abstinent (where abstinence is the preferred and usual life-style of the subject), starting at screening and continuing throughout the clinical study period, and for 30 days after study drug administration.

1. Must have a confirmed clinical history of sterility
  
  Or
2. Must be postmenopausal as defined as: amenorrhea for at least 1 year prior to screening and a laboratory confirmed serum follicle stimulating hormone (FSH) level ≥ 40mIU/mL.
Female subjects must agree not to breastfeed starting at screening and continuing throughout the clinical study period, and for 90 days after study drug administration.
Female subjects must agree not to donate ova starting at screening and continuing throughout the clinical study period, and for 90 days after study drug administration.
Subject must be competent to understand the nature of the study & capable of giving written informed consent. Be willing to report for the scheduled study visits and communicate to study personnel about adverse events and concomitant medication use.
Subject must abstain from the following foods from 1 week prior to study drug administration until the last PK sample has been obtained: grapefruit juice or products, pomegranate juice or products, foods containing poppy seeds, and/or drinks or foods containing quinine (e.g., tonic water) or Seville oranges (e.g. orange marmalade).
Subject agrees not to participate in another interventional study while participating in the present clinical study.

Exclusion criteria

Female subject who has been pregnant within the 6 months prior to screening or breastfeeding within the 3 months prior to screening.
