Primary Outcome Measures :
  1. Percentage Change from Baseline in Rectal/pouch Polyp Burden at Week 24 [ Time Frame: Baseline, Week 24 ]
    Percentage change from baseline in rectal/pouch polyp burden (sum of the polyp diameters) at Week 24 will be determined through endoscopy.


Secondary Outcome Measures :
  1. Percentage Change from Baseline in Number of Colorectal Polyps [ Time Frame: Baseline, Weeks 24 and 52 ]
    Percentage change from baseline in number of colorectal polyps will be determined.

  2. Percentage Change from Baseline in Number of J-pouch Polyps [ Time Frame: Baseline, Weeks 24 and 52 ]
    Percentage change from baseline in number of J-pouch polyps will be determined.

  3. Percentage Change from Baseline in J-pouch Polyp Burden [ Time Frame: Baseline, Weeks 24 and 52 ]
    Percentage change from baseline in J-pouch polyp burden (sum of polyp diameters) will be determined.

  4. Percentage Change from Baseline in Number of Duodenal Polyps [ Time Frame: Baseline, Weeks 24 and 52 ]
    Percentage change from baseline in number of duodenal polyps will be determined.

  5. Percentage Change from Baseline in Duodenal Polyp Burden [ Time Frame: Baseline, Weeks 24 and 52 ]
    Percentage change from baseline in duodenal polyp burden (sum of polyp diameters) will be determined.

  6. Change in International Society for Gastrointestinal Hereditary Tumors (InSiGHT) Stage [ Time Frame: Baseline, Weeks 24 and 52 ]
    Change in InSiGHT stage will be determined. Various stages of InSiGHT staging system are defined as: Stage 0: 0-10 polyps, all less than (<)5 millimeter (mm); Stage 1: 10-25 polyps, most < 5 mm, none greater than (>) 1 centimeter (cm); Stage 2: 10-25 polyps, any > 1 cm, 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; and Stage 4: > 25 polyps amenable to complete removal, or any incompletely excised sessile polyp showing HGD, any invasive cancer).

  7. Change in Spigelman Stage Score [ Time Frame: Baseline, Weeks 24 and 52 ]
    Change in Spigelman stage score will be determined. Spigelman classification system measures risk of developing duodenal cancer in familial adenomatous polyposis (FAP). It has been classified in following stages- Stage 0 (0 points); Stage 1 (1-4 points); Stage 2 (5-6 points); Stage 3 (7-8 points); and Stage 4 (9-12 points). The total score ranges from 0 to 12. Points are accumulated for polyps' number, size, histology and severity of dysplasia. Stage 1 indicates mild disease, whereas stage 3-4 indicates severe duodenal polyposis.

  8. Trough Concentration of Guselkumab [ Time Frame: Weeks 0, 4, 8, 12, 16, 20, 24, 32, 40, and 48 ]
    Serum samples will be analyzed to determine trough concentrations of guselkumab using a validated specific, and sensitive method.

  9. Number of Participants with Anti-guselkumab Antibodies [ Time Frame: Weeks 0, 4, 8, 12, 16, 20, 24, 32, 40, and 48 ]
    Number of participants with Anti-guselkumab antibodies will be determined.

  10. Anti-guselkumab Antibodies Serum Titers [ Time Frame: Weeks 0, 4, 8, 12, 16, 20, 24, 32, 40, and 48 ]
    Serum samples will be screened for antibodies binding to guselkumab and the titer of confirmed positive samples will be reported.

  11. Number of Participants with Adverse Events as a Measure of Safety [ Time Frame: From Screening up to 60 Weeks ]
    An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

  12. Number of Participants with Vital Sign Abnormalities as a Measure of Safety and Tolerability [ Time Frame: From Screening up to 52 Weeks ]
    Number of participants with vital sign abnormalities will be reported. Vital signs includes temperature, pulse/heart rate, respiratory rate and blood pressure.

  13. Number of Participants with Clinical Laboratory Abnormalities as a Measure of Safety and Tolerability [ Time Frame: From Screening up to 52 Weeks ]
    Number of participants with clinical laboratory abnormalities will be reported. Blood samples for serum chemistry and hematology will be collected at predefined time points for clinical laboratory testing.

  14. Relative Changes to Baseline in Levels of Interleukin (IL)-23 Effector Proteins in Biopsy Tissue [ Time Frame: Baseline, Weeks 12, 24, and 52 ]
    Relative Changes to Baseline in levels of IL-23 effector proteins in biopsy tissue will be measured.
