简要总结

The purpose of this study is to evaluate the safety and tolerability of PRV-300 for 12 weeks in subjects with active ulcerative colitis.

Subjects will receive either PRV-300 or placebo treatment. Each group will receive study drug over a total of 12 weeks, followed by an 8-week safety follow-up period.

详细描述

This is a Phase 1b, randomized, double-blind, placebo-controlled, parallel-group, multicenter study in adult subjects with moderately to severely active UC. Randomization will be stratified by Mayo score.

Subjects will receive either PRV-300 or placebo treatment. Each group will receive study drug over a total of 12 weeks, followed by an 8-week safety follow-up period. The total duration of the study will be 20 weeks, excluding the screening period.

The primary objective is to evaluate the safety and tolerability of PRV-300 for 12 weeks in subjects with active UC.

The secondary objectives are to evaluate the effect of PRV-300 for 12 weeks in subjects with active UC on:

  • Pharmacodynamics: Changes in gene scores in colonic biopsies over the course of treatment.
  • Pharmacokinetics: Peak (Cmax) and trough (Cmin) serum concentrations of PRV-300 in subjects with active UC.
  • Immunogenicity: Immunogenicity of PRV-300 in subjects with active UC
  • Endoscopic: Trends in endoscopic disease activity in subjects with active UC.

入选标准

  • Subject must be a man or woman aged 18-75 years, inclusive.
  • Subject has a clinical diagnosis of UC at least 3 months before screening.
  • Subject has moderately to severely active UC, defined as a Mayo score of 6 to 12, inclusive, at screening.
  • Subject has a Mayo endoscopic subscore of ≥2 based on central read of the video sigmoidoscopy at screening.
  • Subject must be willing and able to adhere to the prohibitions and restrictions specified in this protocol.

排除标准

  • Subject has severe extensive colitis as evidenced by any of the following:
  • Current hospitalization for the treatment of UC.
  • Investigator judgment that the subject is likely to require a colectomy within 12 weeks of baseline.
  • Temperature ≥37.8 ºC (oral or tympanic) and a heart rate >90 bpm.
  • Subject has UC limited to <15 cm of the colon.
  • Subject has a diagnosis of CD or the presence or history of fistula or indeterminate colitis.
  • Presence of a gastrostomy, jejunostomy, ileostomy or colostomy.
  • Subject has had or is expected to have surgery for active gastrointestinal bleeding, peritonitis, intestinal obstruction, or intra-abdominal or pancreatic abscess requiring surgical drainage, or other conditions that may confound study evaluations from 2 months before screening through the end of this study.
  • Presence of symptomatic colonic or small bowel obstruction
  • History of colonic resection
  • History of colonic mucosal high-grade dysplasia
  • Subject has chronic or recurrent infectious disease
  • Subject has positive serology to human immunodeficiency virus (HIV) 1 or 2, hepatitis B virus (HBV) or hepatitis C virus (HCV) at screening.
  • Subject has any known malignancy or has a history of malignancy (with the exception of basal cell carcinoma; squamous cell carcinoma in situ of the skin; or cervical carcinoma in situ that has been treated with no evidence of recurrence; or squamous cell carcinoma of the skin that has been treated with no evidence of recurrence within 5 years before screening).
  • Subject has ever received PRV-300 (or CNTO 3157) or has known allergies, hypersensitivity, or intolerance to PRV-300 or its excipients; or known or suspected intolerance or hypersensitivity to any biologic medication or known allergies or clinically significant reactions to murine, chimeric, or human proteins, to monoclonal antibodies or antibody fragments; or a history of severe allergic reactions, angioedema, or anaphylaxis that might suggest risk for a reaction to a biologic agent.
  • Subject has any condition for which, in the opinion of the Investigator, participation would not be in the best interest of the subject (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
