A Study of JNJ-64251330 in Participants With Familial Adenomatous Polyposis
- Conditions
- Adenomatous Polyposis Coli
- Interventions
- Drug: JNJ-64251330
- Registration Number
- NCT05014360
- Lead Sponsor
- Janssen Research & Development, LLC
- Brief Summary
The purpose of this study is to determine the effect of JNJ-64251330 in participants with Familial Adenomatous Polyposis (FAP) on colorectal polyp burden (sum of the polyp diameters).
- Detailed Description
Familial adenomatous polyposis (FAP) is the most common polyposis syndrome. It is an autosomal dominant inherited disorder characterized by the early onset of hundreds to thousands of adenomatous polyps throughout the colon. JNJ-64251330 (lorpucitinib) is an oral, small molecule, potent pan-janus kinase (JAK) inhibitor that blocks phosphorylation of Signal Transducer and Activator of Transcription (STAT) proteins. pSTAT induces transcription of multiple genes involved in the progression of inflammatory disease. JNJ-64251330 has chemical properties that limits the amount of drug in the blood while delivering the drug to the tissues of the gut. Local inhibition of JAK in the gut may present a promising method to treat inflammatory diseases of the intestinal tract, such as FAP. The study consists of 3 phases: screening phase (30 days) a treatment phase (24 weeks), and follow-up visit (up to 30 days after last dose of study drug). The total duration of the study will be up to 32 weeks. Study evaluations will include efficacy via endoscopies, safety (monitoring of adverse events (AE), serious adverse events (SAEs), events of infections including tuberculosis (TB), clinical laboratory blood tests (complete blood count and serum chemistries), vital signs, and concomitant medication review), pharmacokinetics, pharmacodynamic and biomarkers evaluations.

Group Intervention Description JNJ-64251330 JNJ-64251330 Participants will receive oral dose of JNJ-64251330 twice daily for 24 Weeks.
- Primary Outcome Measures
Name Time Method Percentage Change from Baseline in Colorectal Polyp Burden for all Polyps at Week 24 Baseline and Week 24 Percentage change from baseline in colorectal polyp burden for all polyps (the sum of the polyp diameters) at Week 24 will be reported.
Percentage Change from Baseline in Colorectal Polyp Burden for Polyps >=2 mm at Week 24 Baseline and Week 24 Percentage change from baseline in colorectal polyp burden (sum of the polyp diameters) for polyps greater than or equal to (\>=) 2 millimeters (mm) at Week 24 will be reported.
- Secondary Outcome Measures
Name Time Method Percentage Change in Number of Colon Polyps Baseline and Week 24 Percentage change in number of colon polyps will be reported.
Percentage Change in Number of Rectal Polyps Baseline and Week 24 Percentage change in number of rectal polyps will be reported.
Percentage Change in Number of J-pouch Polyps Baseline and Week 24 Percentage change in number of J-pouch polyps (for participants with an ileal pouch-anal anastomosis \[IPAA\]) will be reported.
Percentage Change in Number of Duodenal Polyps Baseline and Week 24 Percentage change in number of duodenal polyps will be reported.
Percentage Change in Colon Polyp Burden for all Polyps, Polyps >=2 mm and Polyps >=5 mm Baseline and Week 24 Percentage change in colon polyp burden for all polyps, polyps \>=2 mm and polyps \>=5 mm will be reported.
Percentage Change in Rectal Polyp Burden for all Polyps, Polyps >=2 mm and Polyps >=5 mm Baseline and Week 24 Percentage change in rectal polyp burden for all polyps, polyps \>=2 mm and polyps \>=5 mm will be reported.
Percentage Change in J-Pouch Polyp Burden for all Polyps, Polyps >=2 mm and Polyps >=5 mm Baseline and Week 24 Percentage change in J-Pouch polyp (for participants with an IPAA) burden for all polyps, polyps \>=2 mm and polyps \>=5 mm will be reported.
Percentage Change in Duodenal Polyp Burden for all Polyps, Polyps >=2 mm and Polyps >=5 mm Baseline and Week 24 Percentage change in duodenal polyp burden for all polyps, polyps \>=2 mm and polyps \>=5 mm will be reported.
Change in International Society for Gastrointestinal Hereditary Tumors (InSiGHT) Polyposis Stage (with and Without Colon) Baseline and Week 24 Change in InSiGHT stage will be reported. Various stages are defined as: a) With Colon: Stage 0: 0-10 polyps,all less than \[\<\]5mm); Stage 1: 20-200 polyps,most \<5 mm, none, \>1 centimeters\[cm\]; Stage 2: 200-500 polyps,\<10 that are \>1 cm; Stage 3: 500-1000 polyps or any number if there are 10-50 that are \>1 cm and amenable to complete polypectomy; Stage 4: \>1000 polyps and/or any polyps grown to confluence and not amenable to simple polypectomy, any invasive cancer; b) Without Colon: Stage 0: 0 -10 polyps, all \<5 mm; Stage 1: 10-25 polyps most \<5 mm, none \>1 cm; Stage 2: 10-25 polyps, any \>1 amenable to complete removal; Stage 3: \>25 polyps amenable to complete removal, or any incompletely removed sessile polyp, or any evidence of high-grade dysplasia (HGD), even if completely excised; Stage 4: \>25 polyps not amenable complete removal, or any incompletely excised sessile polyp showing HGD; any invasive cancer.

The higher the score, the more severe or advanced the FAP disease in the duodenum.
