Abstract Background Ustekinumab (UST) is approved for the treatment of adults with moderate to severe Crohn’s disease (CD) or ulcerative colitis. In the UniStar study, the pharmacokinetics (PK) of UST and its relationship with efficacy was evaluated in children who failed prior therapy. UniStar consisted of a PK portion (week 0–16) and extension (week 16–216); we report data through week 16. Methods UniStar is a multicentre, double-blind study (NCT02968108) designed to assess the PK, safety, and efficacy of UST in children (2–<18 years) with moderately to severely active CD, Paediatric CD Activity Index (PCDAI) score >30, and evidence of inflammation as measured by C-reactive protein >3.0 mg/l or faecal calprotectin >250 µg/g or ulcerations on ileocolonoscopy despite adequate treatment with corticosteroids and/or immunomodulators and/or anti-TNF therapies. Patients were randomised (1:1) and stratified by body weight (BW) and prior anti-TNF use for induction to one of 2 weight range-based IV doses: 130mg vs. 390 mg if BW ≥40 kg and 3mg/kg vs. 9 mg/kg if BW <40 kg. At week 8, all patients received a single subcutaneous (SC) UST maintenance dose of 90mg if BW ≥40 kg or 2 mg/kg if BW <40 kg. UST PK outcomes were assessed and compared with adult Phase 3 CD trials. Results 44 patients (59% ≥40 kg; >90% anti-TNF exposed) were randomised and treated with UST (n = 23 lower dose; n = 21 higher dose). Baseline demographics were generally similar between treatment groups. Most patients (67%) had a severe CD (PCDAI >40). At weeks 0 (1 h after infusion), 3, 6, and 8, mean serum UST concentrations (SUC) in the lower- (51.3, 7.7, 3.0, 1.6 μg/ml) and higher-dose groups (149.0, 23.7, 9.1, 4.8 μg/ml) were generally dose proportional (Figure 1a). Following SC UST at week 8, the impact of the difference in induction doses had diminished by week 16 when mean SUC was 1.5 µg/ml in the lower-dose group vs. 1.8 µg/ml in the higher-dose group. In the overall paediatric population (combined doses), serum UST concentrations were comparable to those in the reference adult CD studies (Figure 1b and c). In the higher dose group, we observed a pattern toward lower mean serum UST concentrations in patients weighing <40 kg vs. those weighing ≥40 kg; thus, UST should be dosed higher in patients <40 kg. Overall at week 8 and week 16, more patients achieved clinical response (PCDAI reduction ≥15) and biomarker improvement with higher UST concentrations, although this pattern was not observed for clinical remission (PCDAI ≤10; Figure 2). Conclusion Overall, UST PK was generally comparable between paediatric and adult patients with CD. A trend towards better efficacy outcomes with higher UST concentrations was observed in children similar to adults with CD.

Abstract Background Present therapies leave an unmet need for early and effective treatment for patients with Crohn’s disease (CD). Risankizumab (RZB), a humanized immunoglobulin G1 monoclonal antibody against the p19 subunit of interleukin-23, was evaluated as an induction therapy to induce early clinical remission and response in patients with moderate-to-severe CD in two double-blind, randomized, placebo (PBO)-controlled studies (ADVANCE [NCT03104413] and MOTIVATE [NCT03105128]). Methods Patients with moderate-to-severe CD (CD Activity Index [CDAI] of 220–450, Simple Endoscopic Score for CD [SES-CD] ≥ 6 [≥ 4 for isolated ileal disease] excluding the narrowing component, and average daily [liquid/very soft] stool frequency [SF] ≥ 4 and/or average daily abdominal pain [AP] score ≥ 2) who had inadequate response or intolerance to conventional and/or biologic treatment (ADVANCE), or biologic treatment only (MOTIVATE) were randomised 2:2:1 (ADVANCE) or 1:1:1 (MOTIVATE) to receive intravenous RZB 600 mg, RZB 1200 mg, or PBO as induction therapy at weeks 0, 4, and 8. Clinical remission (per either CDAI or a composite of SF and AP criteria), clinical response (per CDAI criterion), and enhanced clinical response (per a composite of SF and AP criteria) were evaluated at weeks 4, 8, and 12 (endpoints defined in Figure 1 footnotes). Safety was assessed throughout the studies. Results A total of 1419 patients from ADVANCE (N = 850) and MOTIVATE (N = 569) respectively, were randomised and included in the intention-to-treat population. In both studies, starting at week 4 (the first prespecified measurement), greater proportions of RZB 600 mg or RZB 1200 mg- vs PBO-treated patients achieved clinical remission per either CDAI (P = .01/P < .05) or SF/AP criteria (P < .01/P < .01), clinical response per CDAI criterion (P = .001/P < .01), and enhanced clinical response per SF/AP criteria (P < .01/P = .14) (Figure 1). For both RZB 600 mg and RZB 1200 mg, the efficacy and treatment effect increased through week 12 (P ≤ .001/P ≤ .001) (Figure 1). Treatment with RZB 600 mg or 1200 mg was well tolerated, and no new safety risks were identified.1,2 Conclusion Induction therapy with both RZB 600 mg and 1200 mg intravenous resulted in significantly greater clinical remission and response vs PBO as early as week 4 and sustained through week 12 in patients with moderate-to-severe CD who had inadequate response or intolerance to conventional and/or biologic treatment.

Abstract Background Ustekinumab (UST) is approved for the treatment of adults with moderate to severe Crohn’s disease (CD). The objective of this study was to evaluate the pharmacokinetics (PK), safety, and efficacy of UST in paediatric patients with moderately to severely active CD who had failed treatment with corticosteroids (CS) and/or immunomodulators (IM) and/or anti-tumour necrosis factor (TNF) therapies. Here, we report the safety and efficacy results through Week 16; PK results are reported separately. Methods This was a Phase 1, multicentre, 16-week, double-blind induction dose-ranging study (NCT02968108) in patients aged 2 to <18 years (body weight [BW] ≥10 kg) with a Paediatric CD Activity Index (PCDAI) score >30 and at least an abnormal C-reactive protein >3.0 mg/l or faecal calprotectin >250 µg/g), or ulcerations in the ileum or colon upon ileocolonoscopy despite adequate treatment with CS ± IM ± anti-TNF therapy. Patients were randomised (1:1) and stratified by weight and prior anti-TNF use for induction to one of 2 weight range-based intravenous (IV) doses: 130mg vs. 390 mg if BW ≥40 kg and 3 mg/kg vs. 9 mg/kg if BW <40 kg. At week 8, all patients received a single subcutaneous (SC) UST maintenance dose of 90mg if BW ≥40 kg or 2 mg/kg if BW <40 kg. Results Forty-four patients (59% ≥40kg BW; >90% anti-TNF exposed) were randomised (n = 23 lower dose; n = 21 higher dose) and treated with UST. Baseline characteristics are summarised in Table 1. At week 16, in the lower dose and higher dose groups, 52%/52% achieved clinical response (reduction in PCDAI ≥15) and 22%/29% had clinical remission (PCDAI ≤10), respectively (Table 2). In addition, 32% and 28% of patients showed endoscopic response (reduction in Simple Endoscopic Score for CD of ≥50%), respectively. Through week 16, 73% of patients reported ≥1 adverse event (AE; 82.6% lower dose vs. 62% higher dose); 2 discontinued due to AEs (1 in each group). Serious AEs occurred in 16% of patients (26% lower dose and 5% higher dose, with CD exacerbation being the most frequent (13%/5%, respectively). Infections occurred in 41% of patients (1 was serious, which was intestinal abscess that spontaneously resolved with sequelae). No injection site reactions, opportunistic infections, malignancies, or deaths were reported. No antibodies to UST were observed. Conclusion As early as 3 weeks and through 16 weeks, both the lower and higher doses of UST (IV week 0 and SC at week 8) improved clinical and endoscopic disease activity in this previously treatment-refractory group of children with CD. The safety profile was consistent with that for UST in adults with CD.

TPS4142 Background: Advanced cholangiocarcinoma (CC) is a life-threatening disease for which there are limited therapeutic options. Mutations in isocitrate dehydrogenase 1 (mIDH1) occur in up to 25% of intrahepatic CC cases. mIDH1 lead to epigenetic and genetic changes that promote oncogenesis via production of the oncometabolite, D-2-hydroxyglutarate (2-HG). AG-120 is a first-in-class oral inhibitor of the mIDH1 enzyme, and is being tested in a phase 1 study that enrolled 73 patients (pts) with mIDH1 CC who had received a median of 2 prior therapies (range 1–5). AG-120 has demonstrated a favorable safety profile and clinical activity in this study. Among the 72 efficacy evaluable pts (≥1 post-baseline response assessment or discontinued prematurely), 6% (n = 4) had a confirmed partial response and 56% (n = 40) had stable disease. Progression-free survival (PFS) rate at 6 months was 40% as of Dec 16, 2016. The 500 mg once daily (QD) dose of AG-120 was selected for the ongoing phase 3 study in mIDH1 CC described here. Methods: ClarIDHy is a global, phase 3, multicenter, double-blind study randomizing 186 pts with mIDH1 CC in a 2:1 ratio to AG-120 (500 mg QD) or matched placebo (NCT02989857). Key eligibility criteria: nonresectable or metastatic CC; documented mIDH1 based on central laboratory testing; ECOG 0–1; measurable disease (RECIST v1.1); documented disease progression following ≤2 prior systemic therapies in the advanced setting, including at least 1 gemcitabine- or 5-fluorouracil-containing regimen; and no prior mIDH inhibitor therapy. Crossover from the placebo arm to the AG-120 arm will be permitted. The primary endpoint is PFS as assessed by an independent review. Secondary endpoints include safety, tolerability, overall response rate, overall survival, pharmacokinetic and pharmacodynamic analyses on plasma, and quality of life as assessed by the EORTC QLQ-C30, EORTC QLQ-BIL21, and EQ-5D-5L instruments. An independent data monitoring committee will monitor the data throughout the study. The ClarIDHy study is currently activated at participating sites in the US and will be activated in centers throughout Europe and in South Korea. Clinical trial information: NCT02989857.

Abstract Background Endoscopic healing has become a critical treatment target in Crohn’s disease (CD). Risankizumab (RZB), a humanized immunoglobulin G1 monoclonal antibody against the p19 subunit of interleukin 23, is being investigated as a treatment for moderate-to-severe CD. This analysis assessed different endoscopic endpoints in patients treated with RZB induction therapy in two double-blind, randomised, placebo (PBO)-controlled studies (ADVANCE [NCT03104413] and MOTIVATE [NCT03105128]). Methods Patients with moderate-to-severe CD (CD Activity Index [CDAI] of 220–450, Simple Endoscopic Score for CD [SES-CD] ≥ 6 [≥ 4 for isolated ileal disease] excluding the narrowing component, and average daily [liquid/very soft] stool frequency [SF] ≥ 4 and/or average daily abdominal pain [AP] score ≥ 2) who had demonstrated prior inadequate response or intolerance to conventional and/or biologic treatment (ADVANCE) or to biologic treatment (MOTIVATE) were randomised 2:2:1 (ADVANCE) or 1:1:1 (MOTIVATE) to receive intravenous (IV) RZB 600 mg, RZB 1200 mg, or PBO at weeks 0, 4, and 8. This analysis evaluated the proportion of patients who achieved endoscopic remission ulcer-free endoscopy (ie, absence of ulcers), and composite endpoints of CDAI clinical response and endoscopic response, and enhanced clinical response and endoscopic response at week 12 (endpoints defined in Figure 1 footnotes). All endoscopies were centrally read by a blinded reviewer. Safety was assessed throughout the studies. Results In ADVANCE and MOTIVATE, 850 and 569 patients, respectively, were randomised and included in the intent-to-treat population for this analysis. At week 12 greater proportions of RZB- vs PBO-treated patients in both studies achieved endoscopic remission (P ≤ .001), ulcer-free endoscopy (P ≤ .01), CDAI clinical response and endoscopic response (P ≤ .001), and enhanced clinical response and endoscopic response (P ≤ .001; Figure 1). Treatment with RZB 600 mg or 1200 mg was well tolerated, and no new safety risks were identified.1,2 Conclusion Induction therapy with IV RZB 600 mg or 1200 mg resulted in improved outcomes at week 12 compared with PBO as assessed by endoscopy and by composite endoscopic-clinical endpoints in patients with moderate-to-severe CD.

Abstract Background Vedolizumab (VDZ) is a gut-selective, humanised, monoclonal α 4β 7 integrin antibody for the treatment of patients with moderately to severely active ulcerative colitis (UC) or Crohn’s disease (CD). VDZ is currently an intravenous (IV) therapy; a subcutaneous (SC) formulation is under development to provide patients with an alternative route of administration for maintenance treatment for UC and CD. Here we present the first data from the phase 3 study of VDZ SC maintenance treatment in CD. Methods VISIBLE 2 (NCT02611817; EudraCT 2015-000481-58) was a randomised, double-blind, placebo (PBO)-controlled phase 3 trial of VDZ SC as maintenance treatment in adults with moderately to severely active CD. Patients (n = 644) received open-label VDZ 300mg IV induction therapy at Weeks 0 and 2. At Week 6, clinical responders (defined as patients with a ≥70-point decrease in CD Activity Index [CDAI] from baseline) were randomly assigned to receive vedolizumab SC (108 mg every 2 weeks [Q2W]), or placebo (Q2W) for up to 52 weeks. The primary endpoint was clinical remission at Week 52 (defined as CDAI score ≤150). Rank-ordered secondary endpoints were enhanced clinical response at Week 52 (a drop of ≥100 in CDAI score), corticosteroid (CS)-free clinical remission at Week 52, and clinical remission at Week 52 in anti-tumour necrosis factor (TNF)-naïve patients. Finally, VDZ immunogenicity and predefined adverse events of special interest were assessed. Results Patients who responded to VDZ IV induction at Week 6 (n = 409) were randomised to VDZ SC (n = 275) or PBO (n = 134) maintenance and received at least 1 dose of study drug; 61% and 53%, respectively, were previously exposed to anti-TNF therapy. At Week 52, 48.0% of patients on VDZ SC vs. 34.3% on PBO were in clinical remission (p = 0.008, Figure). Enhanced clinical response at Week 52 was reached by 52.0% vs. 44.8% of patients on VDZ SC vs. PBO, respectively (p = 0.167). Among patients on concomitant CS at baseline (VDZ SC, n = 95; PBO, n = 44), 45.3% receiving VDZ SC vs. 18.2% receiving PBO achieved CS-free clinical remission at Week 52. Of anti-TNF-naïve patients (VDZ SC, n = 107; PBO, n = 63), 48.6% vs. 42.9% were in clinical remission at Week 52 in the VDZ SC and PBO arms, respectively. Injection-site reactions were reported for <3% of patients treated with VDZ SC. Serious infections, malignancy, and liver injury were ≤5% for both arms. Anti-VDZ antibodies were detected in 7 (2.5%) patients treated with VDZ SC arm; 4 of 7 patients developed neutralising antibodies. No new safety signals were observed. Conclusion Among VDZ IV induction responders, significantly more patients on maintenance VDZ SC than PBO achieved clinical remission at Week 52. The safety findings with VDZ SC remain in line with the known safety profile of VDZ IV in patients with CD.
