Abstract Background: ACH, the most common non-lethal form of skeletal dysplasia, is characterized by defective endochondral ossification resulting from gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone formation. Current treatment options are non-targeted, ineffective, or painful interventions aimed at preventing or treating complications. Infigratinib is an orally bioavailable and selective FGFR1-3 tyrosine kinase inhibitor in development for FGFR-related conditions. In vitro data with infigratinib showed inhibition of FGFR1-3 activity with reversal of established growth arrest in chondrocytes. In vivo studies revealed dose-dependent improvements in foramen magnum and long bone length in Fgfr3Y367C/+ mice following treatment with infigratinib. Methods: PROPEL2 is a prospective, phase 2, open-label study of infigratinib in children with ACH. Children 3-11 years of age with ACH who have completed at least 6 months of observation in the observational PROPEL study are eligible to participate. PROPEL2 consists of dose escalation with an extended treatment phase, designed as dose finding, followed by a dose-expansion phase to confirm the selected dose and to provide evidence of efficacy. The primary endpoints of the dose-escalation/extended treatment phase are treatment-emergent adverse events and change from baseline in annualized growth velocity. Subjects (n=40) will be enrolled in ascending dose cohorts of approximately 10 subjects/cohort (4 cohorts planned) and treated for 6 months at their assigned dose, continuing for an additional 12 months with dose modifications as required. Up to 20 new subjects will be enrolled in the dose-expansion phase and receive infigratinib (mini-tablets, administered orally once daily) for 12 months. Secondary objectives include: safety/tolerability of infigratinib; changes from baseline in anthropometric parameters, including body proportions; and the pharmacokinetic/pharmacodynamic profile of infigratinib. An exploratory objective is evaluation of changes in ACH disease burden. Current Status: PROPEL2 is currently enrolling - the first subject was entered in July 2020. The planned total enrollment is 60 children with ACH (n=40 in the dose-escalation/extended treatment phase; n=20 in the dose-expansion phase). Following completion of PROPEL2, subjects have the opportunity to enroll in an open-label long-term extension study to assess the safety and efficacy of long-term administration of infigratinib in children with ACH.

Abstract Background Vedolizumab, a gut-selective, α 4β 7 integrin antagonist, has been established as an effective and safe treatment for patients with UC or CD in the GEMINI phase 3 program and long-term safety (LTS) study. An extended access program (XAP) was initiated to provide continued access to patients who were benefiting from vedolizumab in GEMINI LTS and to monitor safety. We now report persistence and safety results from a 2-year data analysis. Methods Vedolizumab XAP (NCT02743806) is a phase 3b/4 prospective, open-label, multinational interventional study. A rollover from GEMINI LTS (NCT00790933) to the XAP, patients reduced dosing frequency from vedolizumab 300 mg IV every 4 weeks (Q4W) to every 8 weeks (Q8W) or remained on vedolizumab 300 mg IV Q4W if medically indicated. This 2-year data analysis assessed persistence on Q8W dosing after dosing frequency reduction, need for escalation to Q4W dosing, incidence of relapse (defined as dose escalation, study withdrawal due to adverse event, loss of adequate benefit from vedolizumab, or increased corticosteroid [CS] or immunomodulator dose), and safety 2 years after rollover from GEMINI LTS. Results A total of 311 patients (142 UC, 169 CD) from GEMINI LTS enrolled in the XAP. Median (range) duration of exposure to vedolizumab prior to the XAP was 8.0 years (5.2–10.0) for patients with UC and 7.5 years (5.4–9.9) for patients with CD. Of patients with UC and CD, 93.0% and 84.6%, respectively, reduced dosing frequency to Q8W at XAP start, and 87.3% and 77.5%, respectively, remained on Q8W after 2 years. At baseline, 93.0% of all patients with UC and 88.2% of all patients with CD were in CS-free remission; patients who maintained Q4W dosing at baseline had lower CS-free remission rates (62.5% in UC and 69.2% in CD). Of patients who initiated Q8W dosing at enrolment in the XAP, 95% had no relapse for ≥6 months (97.0% UC, 93.7% CD; Table 1). Only 7.3% of patients required dose escalation to Q4W, and 11.6% experienced relapse during the 2-year follow-up. Times to dose escalation and relapse were similar in patients with UC and CD (Figures 1 and 2). At 2 years, 4 of 8 patients with UC and 4 of 12 patients with CD who required dose escalation to Q4W discontinued vedolizumab early due to loss of benefit or adverse events. Adverse events related to vedolizumab were infrequent; no new or serious events attributed to vedolizumab were reported. Conclusion High patient persistence on Q8W vedolizumab was observed in the first 2 years after reduction of dosing frequency in the XAP. Overall, there were low rates of Q4W dose escalation and CD or UC disease relapse. The safety profile was consistent with previous reports with no new signals observed.

Abstract Background Efficacy and safety of the IL-23 inhibitor risankizumab (RZB) have been assessed in patients with moderate-to-severe Crohn’s disease (CD) following induction/maintenance treatment.1,2 Responders to RZB in a Phase 2 induction/maintenance study2,3 could enrol in an open-label extension (OLE), NCT02513459.4 Final safety and efficacy results from this RZB OLE study are reported here. Methods Patients achieving clinical response (CResp) (decrease from baseline [BL] in CD Activity Index [CDAI] ≥100) without remission (CRem) (CDAI <150) after Period 2 (Week 26) or CResp/CRem after Period 3 (Week 52) of the preceding study1 received open-label 180 mg subcutaneous (SC) RZB every 8 weeks (Q8W) for up to 206 weeks. Patients who lost CResp/CRem at screening of the OLE were re-induced with open-label 600 mg IV RZB at Weeks 0, 4, and 8. Patients receiving re-induction treatment only received subsequent 180 mg SC RZB Q8W if they regained CResp/CRem following re-induction. A centrally read ileocolonoscopy was performed yearly. Treatment-emergent adverse events (AEs) were collected up to 20 weeks after the last RZB dose. CRem and endoscopic remission (ER [CD Endoscopic Index of Severity (CDEIS) ≤4 or CDEIS ≤2 for patients with isolated ileitis at BL]) were reported up to Week 152. Non-responder imputation (NRI) and observed case analysis were used for binary endpoints. Results Sixty-five patients with CD were enrolled in the OLE, with 4 patients re-induced. At BL of the preceding study, median (range) age was 34 (19–67) years and median (range) disease duration was 10 (2–38) years. Sixty patients (92%) were previously exposed to TNF antagonists. In the OLE, median (range) exposure to RZB was 1014.0 (114–1317) days. Twenty-one (32%) patients prematurely discontinued RZB, including 6 (9%) who had developed an AE. AEs were reported in 60 (92%) patients; 23 (35%) experienced serious AEs. The most common AEs were nasopharyngitis (31%), gastroenteritis (23%), and fatigue (20%). Serious infections were reported in 6 (9%) patients and opportunistic infections in 3 (5%) patients. No tuberculosis, malignancies, or deaths occurred. At Week 0 of the current study, 47 (72%) patients were in CRem and 27 (42%) patients had ER. Both CRem and ER were sustained up to Week 152 (Table). Conclusion In this final analysis of patients with CD receiving long-term open-label RZB treatment, the safety profile of RZB remained consistent with previous data² with no new safety signals. Clinical and endoscopic remissions were sustained. References

Abstract Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). The efficacy and safety of tofacitinib have been demonstrated in patients with moderate to severe UC in three Phase 3 studies (OCTAVE Induction 1 and 2 [NCT01465763; NCT01458951]; OCTAVE Sustain [NCT01458574]) [1]. Here, we present updated efficacy and safety data of tofacitinib dose escalation in patients with UC participating in an ongoing, open-label, long-term extension (OLE) study (OCTAVE Open, NCT01470612) [2]. Methods We present updated data from the dose-escalation subpopulation of the OLE study (as of May 2019; database not locked) comprising patients who achieved clinical response (CR) following 8 weeks of tofacitinib 10 mg twice daily (BID) induction therapy, entered OCTAVE Sustain receiving tofacitinib 5 mg BID, experienced treatment failure between Week 8 and Week 52, and subsequently entered OCTAVE Open with escalation to tofacitinib 10 mg BID. Treatment failure was defined as an increase of ≥3 points from maintenance study baseline total Mayo score, plus an increase of ≥1 point in both rectal bleeding subscore and centrally read endoscopic subscore (ES), and an absolute ES of ≥2 after ≥8 weeks of maintenance therapy. CR, mucosal healing (MH) and remission (R) were evaluated at Months 2, 12, 24 and 36 of OCTAVE Open (non-responder imputation and last observation carried forward [NRI-LOCF] and observed data). Safety was evaluated throughout the study. Results Of 944 patients enrolled in the OLE study, the dose escalation subpopulation comprised 59 patients. In these patients, CR, MH and R rates 36 months after dose escalation were, respectively, 40.7%, 39.0% and 30.5% for NRI-LOCF and 95.2%, 86.4% and 66.7% for observed data (Table). Of these 59 patients, 29 had prior tumour necrosis factor inhibitor (TNFi) failure; in these patients, CR, MH and R rates at Month 36 were, respectively, 51.7%, 51.7% and 41.4% for NRI-LOCF, and 100.0%, 92,3% and 75.0% for observed data. Incidence rates for safety events and pt-years’ exposure are reported in the table. Conclusion For most patients who lost initial CR to tofacitinib 10 mg BID induction therapy while on tofacitinib 5 mg BID maintenance therapy, including those with prior TNFi failure, dose-escalation back to 10 mg BID recaptured CR by Month 2 and was generally maintained over 3 years. The safety profile with tofacitinib 10 mg BID in the dose-escalation subpopulation was generally consistent with that in the overall study population, although there was a numerically higher rate of herpes zoster. These analyses are limited by low pt numbers and the absence of a comparator arm. References

Abstract Objective This phase 2 study examined the efficacy and safety of tolvaptan, an aquaretic drug, in the treatment of ascites associated with cancer. Methods In the dose-escalation phase, oral tolvaptan was initiated at a dose of 3.75 mg/day, and the dose was increased daily to 7.5, 15 and 30 mg/day. Dose escalation was terminated once the increase from baseline in the daily urine volume reached 500 ml, at which point the patient proceeded to the maintenance phase of 5–7 days. Improvement of ascites was determined primarily by reduction in body weight and ascitic fluid volume. Results The mean change from baseline in body weight was maintained below 0 kg throughout the study. The mean change (±standard deviation) from baseline in ascitic fluid volume at the end of treatment (EOT) was 237.45 ± 868.14 ml in 33 evaluable patients. Although an increase from baseline in ascitic fluid volume at the EOT was observed in 23 of 33 patients (maximum: 1589.3 ml, minimum: 3.83 ml), a reduction in ascitic fluid volume was observed in the remaining 10 patients (maximum: −2304.3 ml, minimum: −27.5 ml). The common treatment-emergent adverse events included vomiting (5 of 43 patients, 11.6%), abdominal distension, constipation, thirst, blood osmolarity increased and renal impairment (3 of 43 patients, 7.0% each). Conclusions Tolvaptan seemed to have no definitive effect on reducing ascites; however, it might be effective in at least some cancer patients. No new safety concerns were identified at doses of 3.75–30 mg/day.

Abstract Background Filgotinib (FIL) is an orally administered, selective janus kinase 1 (JAK1) inhibitor in development for psoriatic arthritis (PsA). Efficacy and safety of FIL in patients with active PsA were evaluated in a 16-week phase 2 study (EQUATOR, NCT03101670). After 16 weeks, patients could roll-over to an Open Label Extension (OLE) Study (EQUATOR2, NCT03320876) for the purpose of evaluating long-term safety and efficacy. The aim of this analysis was to assess safety and efficacy through 52 weeks of exposure to filgotinib. Methods Patients who completed the randomised, double-blind, placebo-controlled study were eligible for participation in the OLE, during which all patients received once daily (qd) open-label FIL 200mg. In this interim analysis of OLE, for the safety analysis, all data were included from the screening in the core study up to the data cut of 18 April 2019 in the OLE. For the efficacy analysis, all data until OLE Week 52 visit for each patient were included (observed case analysis). Results Of the 131 patients randomised and dosed in EQUATOR, 124 (95%) completed the study and 122 (93%) enrolled in EQUATOR2; 50% were female and mean age was 50. At this interim analysis, 106/122 (87%) remained in the OLE (premature discontinuations during OLE due to: 4 for safety, 11 withdrew consent, and 1 for other reasons). Cumulative patient years of exposure (PYE) on FIL were 160, median time on FIL was 66 weeks. Key safety data are summarised in Table 1. Key ≥Grade 2 treatment-emergent laboratory abnormalities seen with FIL arm (N = 128) compared with PBO (N = 66) were lymphocyte decrease 11.1% vs 4.5%, neutrophil decrease 5.5% vs 0%, ALT increase 1.6% vs 1.5% and creatinine increase 0.8% vs 0%, respectively. At week 52, 34% of the patients fulfilled criteria for minimal disease activity and 81%, 55%, and 33% of patients, respectively, achieved ACR20/50/70 responses. Conclusion FIL 200mg qd was generally well tolerated and the safety profile in PsA was comparable to that observed in the FIL rheumatoid arthritis studies. The data from this interim analysis suggest that further improvement of the patient condition can be expected beyond 16 weeks of treatment. Disclosures L.
