Paediatric patients with moderate-to-severe ulcerative colitis (UC) who fail 5-ASAs, corticosteroids, and immunomodulators have limited alternative approved treatment options. Golimumab is a subcutaneous (SC) anti-tumour necrosis factor (anti-TNF) agent with potential to offer such patients a safe, effective, and convenient treatment option.


PURSUIT PEDS PK is a multicentre open-label study with a pharmacokinetic (PK) portion (week 0–14) and a study extension (week 14–126); we report here results through week 14. Patients aged 2–17 years with moderate-to-severe UC (Mayo score 6–12, endoscopy subs-core ≥ 2) who failed previous therapy as noted above and were naïve to anti-TNF treatment were enrolled. Patients received SC golimumab induction at week 0 and 2 by weight (<45 kg [90 → 45 mg/m2]; ≥45 kg [200 → 100mg]). At week 6, Mayo clinical responders continued golimumab maintenance q4w (< 45kg [45 mg/m2]; ≥ 45kg [100 mg]). Key outcome measures (PK, immunogenicity, efficacy, and safety) were evaluated and compared with those observed in the adult UC Phase 3 study.


In total, 35 patients enrolled and received ≥ 1 dose of golimumab. Baseline characteristics are summarised in Table 1; 85.7% received ≥ 1 concomitant UC medications (oral/parenteral corticosteroids [34.3%], immunomodulators [57.1%], and 5-ASAs [65.7%]). Serum golimumab concentrations from baseline through week 6 were similar between the paediatric and adult populations. Clinical response and remission at week 6 by Mayo score were 60% and 43%, respectively; mucosal healing was noted in 54% (Table 2). These results in the paediatric UC population were generally comparable to or numerically greater than in the adult Phase 3 study. Through week 14, 94.3% of patients reported ≥ 1 adverse event (AE); 8.6% had an AE leading to discontinuation; 37.1% reported infections (none serious); 17.1% reported injection site reactions (all mild); 31.4% reported serious AEs (majority were UC flares). Further, 3 patients were positive for antibodies to golimumab at week 14 using a drug tolerant enzyme immunoassay. No opportunistic infections, malignancies, or deaths were reported.


Golimumab was generally well tolerated in this small open-label study of paediatric patients with UC. The PK, efficacy, and safety outcomes observed were comparable with those previously reported in the golimumab adult UC Phase 3 study.
