Objectives To assess real‐world effectiveness, safety, and usage of erenumab in Canadian patients with episodic and chronic migraine with prior ineffective prophylactic treatments. Background In randomized controlled trials, erenumab demonstrated efficacy for migraine prevention in patients with ≤4 prior ineffective prophylactic migraine therapies. The “Migraine prevention with AimoviG: Informative Canadian real‐world study” (MAGIC) assessed real‐world effectiveness of erenumab in Canadian patients with migraine. Methods MAGIC was a prospective open‐label, observational study conducted in Canadian patients with chronic migraine (CM) and episodic migraine (EM) with two to six categories of prior ineffective prophylactic therapies. Participants were administered 70 mg or 140 mg erenumab monthly based on physician’s assessment. Migraine attacks were self‐assessed using an electronic diary and patient‐reported outcome questionnaires. The primary outcome was the proportion of subjects achieving ≥50% reduction in monthly migraine days (MMD) after the 3‐month treatment period. Results Among the 95 participants who mostly experienced two (54.7%) or three (32.6%) prior categories of ineffective prophylactic therapies and who initiated erenumab, treatment was generally safe and well tolerated; 89/95 (93.7%) participants initiated treatment with 140 mg erenumab. At week 12, 32/95 (33.7%) participants including 17/64 (26.6%) CM and 15/32 (48.4%) EM achieved ≥50% reduction in MMD while 30/86 (34.9%) participants including 19/55 (34.5%) CM and 11/31 (35.5%) EM achieved ≥50% reduction in MMD at week 24. Through patient‐reported outcome questionnaires, 62/95 (65.3%) and 45/86 (52.3%) participants reported improvement of their condition at weeks 12 and 24, respectively. Physicians observed improvement in the condition of 78/95 (82.1%) and 67/86 (77.9%) participants at weeks 12 and 24, respectively. Conclusion One‐third of patients with EM and CM achieved ≥50% MMD reduction after 3 months of erenumab treatment. This study provides real‐world evidence of erenumab effectiveness, safety, and usage for migraine prevention in adult Canadian patients with multiple prior ineffective prophylactic treatments.

In this model, losartan did not improve survival compared to placebo and quinapril and, if anything, increased mortality. Our results suggest that AT1 receptor antagonists and ACE inhibitors are not necessarily equivalent or interchangeable in terms of their effects on cardiac hypertrophy and survival in selected progressive heart failure models.

Purpose:To assess the effect of preservative-free dorzolamide–timolol on nonvisual symptoms and intraocular pressure (IOP) in newly diagnosed and untreated patients with open-angle glaucoma or ocular hypertension.Methods:This was a prospective, 8-week, open-label, Canadian multicenter study. All patients were treated with preservative-free dorzolamide–timolol formulation. The primary outcome was the change in the nonvisual symptom score of the Glaucoma Symptom Scale (GSS-SYMP-6) from baseline to 8 weeks. Secondary effectiveness outcome measures were absolute and percent changes in IOP from baseline to 4 and 8 weeks.Results:One hundred and seventy-eight patients were enrolled. Mean (SD) age was 65.6 (12.1) years and 90 (50.6%) were females. There were 92 patients diagnosed with open-angle glaucoma, 62 with ocular hypertension, and 23 with both diseases (diagnosis was missing for one patient). The mean (SD) GSS-SYMP-6 score increased from 73.6 (21.8) at baseline to 76.1 (20.7) at 8 weeks (P = 0.097). Mean (SD) IOP significantly decreased by 11.7 (5.1) mmHg at 4 weeks (P < 0.001) and by 11.5 (5.3) mmHg at 8 weeks (P < 0.001), representing reductions of −38.5% (P < 0.001) and −38.0% (P < 0.001), respectively.Conclusion:Preservative-free dorzolamide–timolol does not increase eye discomfort while significantly reducing IOP in patients with open-angle glaucoma or ocular-hypertension.

DT alone and DT in combination with a PG are effective in significantly reducing IOP in patients with untreated OAG or ocular hypertension. The treatment was safe and well tolerated with a low incidence of AEs.

Background To determine the effectiveness of sacubitril/valsartan 97/103 mg twice daily (b.i.d.) on tolerability, safety, and quality of life (QoL) in Canadian patients with heart failure with reduced ejection fraction in a real-life setting. Methods In P rospective, Multicenter, Open L a bel, Post-App r ov a l S tudy Ai med at Characterizing the Use of L CZ696 at 97 mg Sacubitril/103 mg Valsartan bid in Patients With HFrEF (PARASAIL), an open-label, prospective, phase IV, multicentre study, outpatients with heart failure with reduced ejection fraction and New York Heart Association functional class II-III were followed up for 12 months. The suggested starting dose of sacubitril/valsartan was 24/26 mg b.i.d. replacing angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, with an uptitration to 97/103 mg b.i.d. or as per clinical judgement. The primary endpoint was the proportion of patients achieving the target dose of sacubitril/valsartan 97/103 mg b.i.d. after 6 months of treatment. Results For the 302 patients included, the mean age was 64.47 years, and a majority of patients (82.8%) belonged to New York Heart Association class II. Overall, 195 (64.6%) patients were on maximum dose of sacubitril/valsartan 97/103 mg b.i.d. after 6 months and 62.3% remained on this dose at month 12. Using patient global assessment, patients experienced an improvement in QoL. For Minnesota Living with Heart Failure Questionnaire scores, a significant decrease from the baseline was observed at weeks 4, 12, and 24 ( P < 0.0001 for all), which indicated an improvement in QoL. The patient global assessment and Minnesota Living with Heart Failure Questionnaire results correlate with moderate but significant changes in Euro quality of life-5D visual analogue scale scores. Conclusions Results of the PARASAIL study in a real-life setting have shown that most patients were on sacubitril/valsartan 97/103 mg b.i.d. and the treatment was well tolerated. The patient-reported outcomes showed an overall improvement in patients’ QoL.

In patients with primary open-angle glaucoma or ocular hypertension and elevated IOP while on monotherapy with latanoprost, switching to dorzolamide-timolol or combining dorzolamide-timolol with latanoprost are effective and safe treatment options for reducing IOP and achieving therapeutic response.
