We assessed potential associations between malignancy and antitumor necrosis factor therapy in patients with Crohn's disease (CD), as this relationship is currently poorly defined. Utilizing data from the Crohn's Therapy, Resource, Evaluation, and Assessment Tool (TREAT™) Registry, a prospective cohort study examining long-term outcomes of CD treatments in community and academic settings, influences of baseline patient/disease characteristics and medications were assessed by survival analysis and multivariate models. Standardized incidence ratios and exact 95 % confidence intervals were determined as the ratio of events observed (TREAT) vs. expected (general population of USA). As of 23 February 2010, 6,273 CD patients (infliximab during registry=3,420 (during or within 1 year before registry=3,764); other-treatments-only: 2,509), were enrolled and, on average, had been followed for 5.2/7.6 years, respectively, for all/currently active patients. Crude cancer incidences were similar between infliximab- and other-treatments-only-exposed patients. Multivariate Cox regression analysis demonstrated that baseline age (hazard ratio (HR)=1.59/10 years; P<0.001), disease duration (HR=1.64/10 years; P=0.012), and smoking (HR=1.38; P=0.045) but neither immunosuppressive therapy alone (HR=1.43; P=0.11), infliximab therapy alone (HR=0.59; P=0.16), nor their combination (HR=1.22, P=0.34) were independently associated with the risk of malignancy. When compared with the general population, no significant increase in incidence was observed in any malignancy category. In an exposure-based analysis, use of immunosuppressants alone (odds ratio=4.19) or in combination with infliximab (3.33) seemed to be associated with a numerically, but not significantly, greater risk of malignancy than did treatment with infliximab alone (1.96) relative to treatment with neither. In the TREAT Registry, age, disease duration, and smoking were independently associated with increased risk of malignancy. Although results for immunosuppressant use were equivocal, no significant association between malignancy and infliximab was observed.

In the final analysis of the phase 3 COU-AA-301 study, abiraterone acetate plus prednisone significantly prolonged overall survival compared with prednisone alone in patients with metastatic castration-resistant prostate cancer progressing after chemotherapy. Here, we present the final analysis of an early-access protocol trial that was initiated after completion of COU-AA-301 to enable worldwide preapproval access to abiraterone acetate in patients with metastatic castration-resistant prostate cancer progressing after chemotherapy. We did a multicentre, open-label, early-access protocol trial in 23 countries. We enrolled patients who had metastatic castration-resistant prostate cancer progressing after taxane chemotherapy. Participants received oral doses of abiraterone acetate (1000 mg daily) and prednisone (5 mg twice a day) in 28-day cycles until disease progression, development of sustained side-effects, or abiraterone acetate becoming available in the respective country. The primary outcome was the number of adverse events arising during study treatment and within 30 days of discontinuation. Efficacy measures (time to prostate-specific antigen [PSA] progression and time to clinical progression) were gathered to guide treatment decisions. We included in our analysis all patients who received at least one dose of abiraterone acetate. This study is registered with ClinicalTrials.gov, number NCT01217697. Between Nov 17, 2010, and Sept 30, 2013, 2314 patients were enrolled into the early-access protocol trial. Median follow-up was 5·7 months (IQR 3·5–10·6). 952 (41%) patients had a grade 3 or 4 treatment-related adverse event, and grade 3 or 4 serious adverse events were recorded in 585 (25%) people. Grade 3 and 4 adverse events of special interest were hepatotoxicity (188 [8%]), hypertension (99 [4%]), cardiac disorders (52 [2%]), osteoporosis (31 [1%]), hypokalaemia (28 [1%]), and fluid retention or oedema (23 [1%]). 172 (7%) patients discontinued the study because of adverse events (64 [3%] were drug-related), as assessed by the investigator, and 171 (7%) people died. The funder assessed causes of death, which were due to disease progression (85 [4%]), an unrelated adverse experience (72 [3%]), and unknown reasons (14 [1%]). Of the 86 deaths not attributable to disease progression, 18 (<1%) were caused by a drug-related adverse event, as assessed by the investigator. Median time to PSA progression was 8·5 months (95% CI 8·3–9·7) and median time to clinical progression was 12·7 months (11·8–13·8). No new safety signals or unexpected adverse events were found in this early-access protocol trial to assess abiraterone acetate for patients with metastatic castration-resistant prostate cancer who progressed after chemotherapy. Future work is needed to ascertain the most effective regimen of abiraterone acetate to optimise patients' outcomes. Janssen Research & Development.

Introduction Ciltacabtagene autoleucel (cilta‐cel) is a novel chimeric antigen receptor T‐cell therapy that is being evaluated in the CARTITUDE‐1 trial (NCT03548207) in patients with relapsed or refractory multiple myeloma (RRMM) who received as part of their previous therapy an immunomodulatory drug, proteasome inhibitor, and an anti‐CD38 monoclonal antibody (i.e., triple‐class exposed). Given the absence of a control arm in CARTITUDE‐1, this study assessed the comparative effectiveness of cilta‐cel and physician's choice of treatment (PCT) using an external real‐world control arm from the Flatiron Health multiple myeloma cohort registry. Methods Given the availability of individual patient data for cilta‐cel from CARTITUDE‐1 and PCT in Flatiron, inverse probability of treatment weighting was used to adjust for unbalanced baseline covariates of prognostic significance: refractory status, cytogenetic profile, International Staging System stage, time to progression on last regimen, number of prior lines of therapy, years since diagnosis, and age. Comparative effectiveness was estimated for progression‐free survival (PFS), time to next treatment (TTNT), and overall survival (OS). A range of sensitivity analyses were conducted. Results Baseline characteristics were similar between the two cohorts after propensity score weighting. Patients with cilta‐cel had improved PFS (HR: 0.18 [95% CI: 0.12, 0.27; p < 0.0001]), TTNT (HR: 0.15 [95% CI: 0.09, 0.22; p < 0.0001]), and OS (HR: 0.25 [95% CI: 0.13, 0.46; p < 0.0001]) versus PCT. Cilta‐cel treatment benefit was robust and consistent across all sensitivity analyses. Conclusion Cilta‐cel demonstrated significantly superior effectiveness over PCT for all outcomes, highlighting its potential as an effective therapy in patients with triple‐class exposed RRMM.

The objective of this study was to contribute long-term safety data for infliximab and other therapies in Crohn's disease (CD). We prospectively evaluated CD patients enrolled in the large, observational Crohn's Therapy, Resource, Evaluation, and Assessment Tool registry, established to compare infliximab safety with conventional nonbiological medications in CD. A total of 6,273 patients were enrolled and evaluated on or before 23 February 2010; 3,420 received infliximab (17,712 patient-years; 89.9% received ≥ 2 infusions) and 2,853 received other-treatments-only (13,251 patient-years). Mean length of patient follow-up was 5.2 years. More infliximab- than other-treatments-only-treated patients had moderate-to-severe (30.6% vs. 10.7%) or severe-to-fulminant (2.5% vs. 0.6%) disease severity (P < 0.001). In the year before enrollment, more infliximab- than other-treatments-only-treated patients required surgical intervention (17.4% vs. 13.6%), medical hospitalization (14.2% vs. 8.8%), prednisone (47.8% vs. 31.4%), immunomodulators (52.0% vs. 32.1%), and narcotic analgesics (17.3% vs. 9.1%). Patient mortality was similar for infliximab- and other-treatments-only-treated patients (0.58 vs. 0.59/100 patient-years). In multivariate logistic regression analyses, treatment with prednisone (hazard ratio (HR) = 2.14, 95% confidence interval (CI) = 1.55, 2.95; P < 0.001) or narcotic analgesics (HR = 1.79, 95% CI = 1.29, 2.48; P < 0.001) and age (HR = 1.08, 95% CI = 1.07, 1.09; P < 0.001) were associated with increased mortality risk. Neither infliximab nor immunomodulator treatment was associated with increased mortality risk. Factors independently associated with serious infections included moderate-to-severe disease activity (HR = 2.24, 95% CI = 1.57, 3.19; P < 0.001), narcotic analgesic treatment (HR = 1.98, 95% CI = 1.44, 2.73; P < 0.001), prednisone therapy (HR = 1.57, 95% CI = 1.17, 2.10; P = 0.002), and infliximab treatment (HR = 1.43, 95% CI = 1.11, 1.84; P = 0.006). Mortality was similar between infliximab- and other-treatments-only-treated CD patients. An increased risk of serious infection with infliximab was observed, although CD severity and use of prednisone or narcotic analgesics carried higher risks.

Abstract Background Patients with high-risk, newly diagnosed multiple myeloma (HR-NDMM) who are ineligible for autologous stem cell transplant (ASCT) have limited first-line treatment options. Recent meta-analyses evaluating the impact of incorporating daratumumab in the backbone regimen on progression-free survival (PFS) have found mixed results in these patients. Materials and Methods A pooled analysis of patient-level data for ASCT-ineligible patients with HR-NDMM [ie, del(17p), t(4;14), t(14;16)] from the MAIA and ALCYONE trials; stratified by study identifier and adjusting for cytogenetic abnormality subtype, baseline performance status, International Staging System stage, myeloma type, and renal impairment; was conducted. Impact of daratumumab on PFS and rates of complete response or better (≥CR), minimal residual disease (MRD)-negative CR, very good partial response or better (≥VGPR), and overall response (ORR) was compared to control. Results Among 101 patients in the daratumumab and 89 patients in the control cohort, median follow-up was 43.7 months. Daratumumab reduced the risk of progression or death by 41% (adjusted hazard ratio for PFS [95% confidence interval (CI)] = 0.59 [0.41-0.85]) versus control. At 36 months, the estimated proportion of patients who did not progress and were still alive was 41.3% in the daratumumab and 19.9% in the control cohort. Rates of ≥CR (41.6% vs. 22.5%), MRD-negative CR (24.8% vs. 5.6%), ≥VGPR (75.2% vs. 46.1%), and ORR (92.1% vs. 74.2%) were higher for daratumumab versus control. Conclusion These findings demonstrate that incorporation of daratumumab in frontline treatment regimens reduced the risk of progression or death and improved response rates among ASCT-ineligible HR-NDMM patients. Using a pooled analysis of patient-level data from the MAIA and ALCYONE clinical trials, this study provides an updated analysis of the effect of daratumumab in cytogenetically high-risk newly diagnosed multiple myeloma.

Background and Objective Ciltacabtagene autoleucel (cilta-cel) is a novel agent being investigated in the single-arm CARTITUDE-1 trial (NCT03548207) for patients with relapsed or refractory multiple myeloma who are triple-class exposed to an immunomodulatory drug, proteasome inhibitor, and an anti-CD38 monoclonal antibody. The objective of this study was to evaluate the comparative efficacy of cilta-cel vs physician’s choice of treatment, as no head-to-head trials have been conducted. Methods An external control arm for CARTITUDE-1 was created from patients in the long-term follow-up for three clinical trials of daratumumab (POLLUX, CASTOR, and EQUULEUS) who satisfied the eligibility criteria of CARTITUDE-1. These patients received physician’s choice of treatment following the discontinuation of study drugs. Inverse probability of treatment weighting was used to align the external control and CARTITUDE-1 populations on important baseline characteristics. Overall response rate, complete response or better rate, progression-free survival, time to next treatment, and overall survival were assessed. Several sensitivity analyses were conducted. Results After propensity score weighting, baseline characteristics were comparable between cohorts. Patients showed improved results with cilta-cel vs physician’s choice of treatment: overall response rate (relative risk: 2.95 [95% confidence interval (CI) 2.27, 3.84; p < 0.0001]), complete response or better (relative risk: 111.70 [95% CI 29.08, 429.06; p < 0.0001]), progression-free survival (hazard ratio [HR]: 0.24 [95% CI 0.15, 0.37; p < 0.0001]), time to next treatment (HR: 0.14 [95% CI 0.09, 0.22; p < 0.0001]), and overall survival (HR: 0.21 [95% CI 0.13, 0.35; p < 0.0001]). Results were consistent across all sensitivity analyses. Conclusions Cilta-cel showed superior efficacy compared with physician’s choice of treatment, making it a promising new treatment option for patients with triple-class exposed relapsed or refractory multiple myeloma.

BackgroundThe phase III SPARTAN study demonstrated that apalutamide significantly improves metastasis-free survival and overall survival vs. placebo in patients with non-metastatic castration-resistant prostate cancer (nmCRPC). However, patients receiving apalutamide experienced falls more frequently vs. those receiving placebo (15.6% vs. 9.0%).Methods806 patients with nmCRPC randomized to apalutamide in SPARTAN and treated with apalutamide in addition to ongoing androgen deprivation therapy (ADT) were included in this post-hoc analysis investigating clinical variables associated with a subsequent fall. Time to a fall was assessed with Cox proportional-hazards models adjusted for baseline characteristics and time-varying factors. Statistical inference was based on final multivariable models.ResultsFalls were reported for 125/803 (15.6%) patients treated with apalutamide and ADT. Most falls were grade 1 or 2 and did not require hospitalization. Median time from randomization to first fall was 9.2 months (range 0.1–25.3 months). In the final multivariable model of both baseline and after-baseline covariates, baseline patient characteristics (older age, poor Eastern Cooperative Oncology Group performance status, history of neuropathy, and α-blocker use before study treatment) remained significantly associated with fall; after-baseline clinical characteristics significantly associated with time to fall were development of neuropathy, arthralgia, and weight loss before fall.ConclusionsThis analysis identified risk factors for fall among nmCRPC patients treated with apalutamide. Clinical management can minimize these identified risks while enhancing patient outcomes. Preventive interventions should be considered when the identified baseline conditions and post-treatment neuropathy, arthralgia, or weight decrease are present, to reduce risk of fall.Trial registrationClinicalTrials.gov: NCT01946204
