Long-Term Study That Measures the Safety and Efficacy of Deucravacitinib (BMS-986165) in Participants With Psoriasis

The main purpose of this study is to evaluate the long-term safety and efficacy of the drug Deucravacitinib (BMS-986165) in participants who have been previously enrolled in an applicable Phase 3 psoriasis study. In addition, the study includes a vaccine cohort to evaluate whether deucravacitinib impacts the humoral immune response to 2 non-live vaccines, the Pneumovax 23 vaccine (pneumococcus), a T-cell independent vaccine, and the Boostrix vaccine (tetanus toxoid), a T-cell dependent vaccine. Additionally, this vaccine cohort assesses the safety of administering these vaccines to subjects with psoriasis receiving deucravacitinib compared to those receiving a placebo.

Inclusion criteria

  • Completion of the protocol-required treatment period in an applicable study of BMS-986165 in moderate-to-severe psoriasis.
  • Women must not be pregnant, lactating, or breastfeeding.
  • Vaccine Cohort:
  • Subject must have moderate-to-severe plaque psoriasis, be currently receiving deucravacitinib treatment in the main IM011075 LTE cohort in the United States, Canada, or Poland, and must have completed at least one year of deucravacitinib treatment.

Exclusion criteria

  • To be eligible for the study, a participant must not have active signs or symptoms of tuberculosis (TB) as judged by the investigator.
  • Vaccine Cohort:
  • Subject received the Pneumovax 23 vaccine ≤ 5 years before Day 1 or a pneumococcal conjugate vaccine ≤ 1 year before Day 1.
  • Subject received the Boostrix vaccine (as single or part of a combination vaccine) ≤ 5 years before Day 1.
  • Other protocol-defined inclusion/exclusion criteria apply

    Time frame: Up to 244 weeks

  2. Incidence of Serious Adverse Events (SAEs)

    Time frame: Up to 244 weeks

  3. Proportion of participants achieving a satisfactory humoral response: pneumococcus

    Time frame: At Week 4 post vaccination

    Vaccine cohort only

    Defined as ≥ 2-fold increase in immunoglobulin (IgG) antibody titers or geometric mean fold rise (GMFRs) titers of ≥ 6

  4. Proportion of participants achieving a satisfactory humoral response: tetanus titers

    Time frame: At Week 4 post vaccination

    Vaccine cohort only

    A serologic response is defined as:

    • Postvaccination titer levels ≥ 0.40 IU/mL if prevaccination IgG antibody titer level is ≤ 0.10 IU/mL OR
    • Postvaccination titer levels of at least a 4-fold increase if prevaccination titer level is > 0.10 IU/mL and ≤ 2.7 IU/mL OR
    • Postvaccination titer levels of at least a 2-fold increase if prevaccination titer level is > 2.7 IU/mL

Secondary outcomes

  1. static Physician Global Assessment (sPGA) 0/1 response

    Time frame: Up to 240 weeks

  2. Psoriasis Area and Severity Index (PASI) 75 response
