Real-world (RW) evidence is needed to evaluate atezolizumab plus bevacizumab (atezo + bev) utilization for hepatocellular carcinoma (HCC) in clinical practice. This retrospective cohort study used administrative claims databases to evaluate treatment patterns in individuals with HCC ≥18 years of age who were initiated on atezo + bev between June 2020 and June 2022. The endpoints of this study were the proportion of individuals who discontinued atezo + bev and received subsequent systemic therapies, time to discontinuation (TTD), and time to next treatment. Overall, 825 individuals were eligible (median age 67 years; 80% male). Over a median follow-up of 15.3 months, most (72%) discontinued atezo + bev, with a median TTD of 3.5 months. A minority (19%) received subsequent therapies, with the most common second-line agents being lenvatinib (6%), cabozantinib (4%), and nivolumab (4%). The median time from index to next treatment post-atezo + bev was 5.4 months. Further research is needed to identify the patients who are most likely to benefit from atezo + bev as well as later-line HCC therapies to optimize overall survival.

Objective: To determine the risk of hip fracture in persons with Alzheimer´s disease (AD) who initiated antiepileptic drugs (AEDs). Methods: In the Medication use and AD (MEDALZ) cohort of 70,719 Finnish community dwellers with clinically verified incident AD diagnosis in 2005– 2011, we identified all incident users of AEDs using national Prescription register. AEDs were classified as older (valproate, carbamazepine, clonazepam, phenytoin, levetiracetam, primidone) or newer (pregabalin, gabapentin, oxcarbazepine, lamotrigine, topiramate). We matched each user to 2 non-users. Incident hip fractures until 2015 were identified from the Care register for health care. We calculated inverse probability of treatment weighted hazard ratios (HR), with 95% confidence intervals, using Cox regression. Results: Altogether 5522 incident users were identified and matched to 11,044 non-users (in both groups, women: 65%; median age: 81 years). Altogether 53.3% of users initiated with newer AEDs (pregabalin 79.8%, gabapentin 10.2%) while 46.7% initiated with older AEDs (valproate 67.6%, carbamazepine 13.0%). Age- and sex-adjusted IR of hip fracture per 100 person-years was 1.8 (95% CI 1.6– 1.9) in non-users and 2.0 (95% CI 1.8– 2.2) in users. Increased risk of hip fracture was observed in users (HR 1.17, 95% CI 1.05– 1.30) compared with non-users. The risk was higher for short duration of use (< 14 weeks, HR 3.64, 95% CI 2.90– 4.58) than for medium duration (14 to < 64 weeks, HR 1.74, 95% CI 1.48– 2.05) or ≥ 64 weeks’ use (HR 1.23, 95% CI 1.08– 1.40), compared to non-users with same follow-up time. Older AEDs had HR of 1.46 (1.03– 2.08) compared with newer AEDs. Conclusion: Our results imply that AED use is associated with an increased risk of hip fracture in people with AD. These findings prompt careful consideration before prescribing AEDs to persons with AD. Persons with AD treated with antiepileptics should be carefully monitored due to their increased risk of falling and fractures.

Background: Several narrative reports document long-term responses to regorafenib treatment in patients with metastatic colorectal cancer (mCRC). However, no large-scale study has assessed long-term responses and there are no established predictors of potential long-term benefit. We carried out an observational study of characteristics of patients treated in real-world clinical practice in the USA using duration of treatment (DoT) as a surrogate for treatment response. Patients and Methods: This retrospective cohort study used a de-identified electronic health record-derived database and included patients aged ≥18 years with mCRC who initiated regorafenib monotherapy between 1 July 2013 and 30 June 2023. Patient cohorts were defined by DoT ≥4 months (LTR4), ≥5 months (LTR5), or ≥6 months (LTR6) and are not mutually exclusive. Results: Of 2444 patients who initiated regorafenib monotherapy during the study, those with long-term response were analyzed: 544 had LTR4 (22%), 367 had LTR5 (15%), and 250 had LTR6 (10%). Most patients with long-term responses had left-sided tumors (65–70%), Eastern Cooperative Oncology Group performance status of 0/1 (67–68%), and liver metastases (55–61%) and had received prior bevacizumab treatment (60–67%). The median age in each group was 66 years, and patients most frequently initiated regorafenib as third-line treatment (31–33%). Median time to regorafenib discontinuation was 6.0–9.3 months among long-term responders. Conclusions: Most patients with long-term responses to regorafenib had favorable performance status at treatment initiation, left-sided tumors, and liver metastases and had received prior bevacizumab treatment. The study highlights that patients in the real-world setting were able to tolerate and maintain long-term responses to regorafenib treatment.
