About
This is a Phase 2b, randomized, multicenter, double-blind, placebo-controlled, multiple-dose study designed to evaluate the efficacy, safety, and tolerability of NDI-034858 in participants with moderate to severe plaque psoriasis. This study will also evaluate the plasma concentrations of NDI-034858 and explore the immune response to NDI-034858 in participants with moderate to severe plaque psoriasis.
Full description
Approximately 259 male and female participants, aged 18 to 70 years (inclusive) were enrolled in this study. Participants were randomized to receive either one of the four doses of NDI-034858, or placebo on Day 1. The goal was to have approximately 50 participants randomized per treatment group (1:1:1:1:1 ratio) on Day 1. During the treatment period, NDI-034858 or placebo was orally administered QD for 12 weeks. The 12 week treatment period was followed by a 4-week safety follow-up period.

- For female participants of childbearing potential involved in any sexual intercourse that could lead to pregnancy: the participant must agree to use a highly effective contraceptive method from at least 4 weeks prior to Day 1 until at least 4 weeks after the last study product administration. Highly effective contraceptive methods include hormonal contraceptives (eg, combined oral contraceptive, patch, vaginal ring, injectable, or implant), intrauterine devices or intrauterine systems, vasectomized partner(s) (provided vasectomy was performed ≥ 4 months prior to screening), bilateral tubal ligation or occlusion, or double barrier methods of contraception (eg, male condom with cervical cap, male condom with diaphragm, and male condom with contraceptive sponge) in conjunction with spermicide.
- Female participants of childbearing potential have had a negative serum pregnancy test at screening and negative urine pregnancy test at Day 1.
- For male participants involved in any sexual intercourse that could lead to pregnancy, participant must agree to use one of the highly effective contraceptive methods listed in Inclusion Criterion 6, from Day 1 until at least 12 weeks after the last study product administration. If the female partner of a male participant uses any of the hormonal contraceptive methods listed above, this contraceptive method should be used by the female partner from at least 4 weeks before Day 1 until at least 12 weeks after the last study product administration.

- Participant is willing to participate and is capable of giving informed consent. Note: Consent must be obtained prior to any study-related procedures.
- Participant must be willing to comply with all study procedures and must be available for the duration of the study.
