Impact of Cardiovascular Comorbidities on the Effectiveness and Safety of Bevacizumab in Older Patients with Metastatic Colorectal Cancer.

BACKGROUND: Cardiovascular comorbidities are not contraindications of bevacizumab for metastatic colorectal cancer. OBJECTIVE: We aimed to evaluate the impact of cardiovascular comorbidities before bevacizumab treatment on overall survival and cardiovascular safety in older patients with metastatic colorectal cancer. METHODS: A 2009-2015 cohort of patients with metastatic colorectal cancer aged ≥ 65 years administered first-line bevacizumab was extracted from the French healthcare reimbursement claims database. Baseline heart failure, hypertension, and venous/arterial thromboembolic events were identified. The 36-month overall survival rate was evaluated using the Kaplan-Meier method, and the impact of cardiovascular comorbidities on the 36-month overall survival using a time-dependent, multivariable, Cox proportional hazards model. The 36-month cumulative incidence of cardiovascular events, and the impact of cardiovascular comorbidities on the likelihood of cardiovascular events were evaluated using the Fine and Gray model, with death as a competing risk. RESULTS: We included 9222 patients (56.4% male; median age 73 years). Two-thirds (66.7%) had baseline cardiovascular comorbidities. The median 36-month overall survival was 20.4 [95% confidence interval (CI) 19.9-21.0] and 21.8 [95% CI 21.1-22.6] months in patients with and without cardiovascular comorbidities, respectively. Age ≥ 75 years, dependency in activities of daily living, radiotherapy, and another targeted therapy were identified as death risk factors, but not cardiovascular comorbidities. At 36 months, cardiovascular events had occurred in 60.2% [95% CI 58.9-61.4] and 44.1% [95% CI 42.3-45.9] of patients with and without cardiovascular comorbidities. Baseline venous thrombosis, female, three or more cardiovascular medications, another targeted therapy, and more than six bevacizumab injections were identified as risk factors for cardiovascular events. CONCLUSIONS: In clinical practice, cardiovascular comorbidities before administering bevacizumab to older patients with metastatic colorectal cancer impacted the cardiovascular safety, but not overall survival. Unless they limit functional independency, older patients with cardiovascular comorbidities should be treated with bevacizumab under close monitoring.

Risk of cancer with immunosuppressants compared to immunomodulators in multiple sclerosis: A nested case-control study within the French nationwide claims database.

PURPOSE: The objective was to compare the risk of malignancies in real-world settings between exclusive immunosuppressant (IS) and immunomodulator (IM) use in multiple sclerosis (MS). METHODS: A nested case-control study was designed within a new-user cohort of all patients with MS who initiated a first IM or IS between 2008 and 2014, and without cancer history, using the information of the SNDS nationwide French claims database. Incident cancer cases were matched with up to six controls on year of birth, sex, initiation date, and disease risk score of cancer. A conditional logistic regression (odds ratio [95% confidence interval]) was used to compare exclusive IS versus IM use during follow-up and according to three use durations. RESULTS: From 28 720 newly treated patients with MS, 407 incident cancers were observed during the follow-up with 2324 matched controls. A significant increase in cancer risk was observed for IS compared with IM (1.36 [1.05, 1.77]), with similar increases for the first 2 years of use but not for ≥2 years (1.06 [0.65, 1.75]). Similar increase was also observed for IS with indications other than MS (1.37 [1.04, 1.81]) but not for IS indicated only in MS (1.03 [0.45, 2.34]). CONCLUSIONS: Compared with IM, a 37% increase in cancer risk was observed for IS with indications other than MS and used for a short duration (≤2 years) but not for IS indicated only in MS. The absence of risk for prolonged exposure of IS with indications other than MS is not in favor of a causal relation with these drugs.

Efficacy and Safety of Tacrolimus 0.1% for the Treatment of Facial Vitiligo: A Multicenter Randomized, Double-Blinded, Vehicle-Controlled Study.

BACKGROUND: Topical calcineurin inhibitors are used off label in the treatment of vitiligo, and there is a lack of placebo-controlled, blinded studies to support their use. OBJECTIVE: This study aimed to compare the efficacy of tacrolimus 0.1% ointment with that of the vehicle for repigmentation in adult patients with facial vitiligo. DESIGN: This study was a 24-week multicenter randomized parallel double-blind study with a 24-week post-treatment follow-up extension. POPULATION: Participants included were adult patients with recent facial vitiligo target lesions (<2 years) without changes in pigmentation or size over the previous 3 months. INTERVENTION: Patients received either tacrolimus 0.1% ointment or vehicle twice daily. MAIN OUTCOMES AND MEASURES: The primary outcome was a therapeutic success, defined as a change ≥75% in the repigmentation of the target lesion between baseline and week 24, measured by ImageJ software. Secondary outcome measures were a variation of the physicians' global assessment scores and patients' satisfaction scores, safety data, and the rate of relapse at week 48. RESULTS: A total of 42 patients were included. Therapeutic success was achieved in 65% of tacrolimus-treated patients versus 0% of vehicle-treated patients at week 24 (P < 0.0001). Only 40% of relapse was observed at 48 weeks. CONCLUSIONS AND RELEVANCE: Twice-daily tacrolimus 0.1% ointment showed superior efficacy to that of the vehicle through the 24 weeks of intervention and 24 weeks of follow-up in adult patients with facial vitiligo. TRIAL REGISTRATION: This study was registered at ClinicalTrials.gov (identifier: NCT02466997).

Pharmacological treatment patterns in heart failure: a population-based cohort study.

BACKGROUND: Although the efficacy and safety of existing therapies of heart failure (HF) have been demonstrated in clinical trials, little is known about the treatment patterns in clinical practice, especially in France. OBJECTIVES: To describe the treatment initiation patterns and the subsequent treatment changes among HF patients, in the first year following an incident hospitalization for HF, in a French real-world setting. METHODS: A cohort of patients aged ≥ 40 years, with an incident hospitalization for HF between 01/01/2008 and 31/12/2013, was identified in the 1/97th permanent random sample of the French nationwide claims database and followed 1 year. HF drug exposure-beta blockers (BB), angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARBs), aldosterone antagonists (AA), diuretics, digoxin, or ivabradine-was assessed quarterly using a Proportion of Days Covered ≥ 66% (≥ 60 days out of the 90 days of the quarter), by considering HF drugs individually or in combination. Drug changes were assessed between each quarter. RESULTS: Between 2008 and 2013, 7387 patients were included. Their mean age was 77.7 years (± 12.0 years) and 51.6% were women. During the follow-up, 24.4% died, 20% were not exposed to any HF treatment, 48.3 to 43.2% had diuretics, one third had BB or ACEI, 9% had ARB or AA, 6% had digoxin, and 2% had ivabradine. The main change occurred between the first and the second quarter for 53.1% of the initially untreated patients. CONCLUSION: This study provides valuable information on treatment patterns after an initial hospitalization for HF.
