The Effectiveness of Trimetazidine Treatment in Patients with Stable Angina Pectoris of Various Durations: Results from the CHOICE-2 Study

Abstract

Introduction

Trimetazidine (TMZ) has been shown to reduce angina symptoms and to increase exercise capacity in randomized clinical trials, but more extensive data would be useful to assess its effects in real-world clinical practice and in patients with different durations of disease.

Methods

CHOICE-2 was a Russian, multicenter, 6-month, open-label, prospective observational study that assessed the effect of adding TMZ modified release 35 mg bid to antianginal treatment in a real-world setting. The present analysis of CHOICE-2 results explored the effects of adding TMZ to background antianginal therapies with regard to the duration of stable angina.

Results

A total of 741 patients with known durations of disease were divided into four groups according to stable angina pectoris (AP) duration, ranging from less than 1 year to more than 9 years. Addition of TMZ led to a significant decrease in the frequency of angina attacks and in the use of short-acting nitrates in all groups. In patients with recently diagnosed angina (AP duration < 1 year), the average number of angina attacks per week decreased significantly from 3.75 ± 4.63 to 0.67 ± 1.51 and in those with advanced disease (AP duration > 9 years) from 5.63 ± 5.24 to 1.32 ± 2.07. Angina-free walking distance also improved significantly. Addition of TMZ also improved patient well-being. Results were achieved rapidly (within 2 weeks), were maintained over 6 months, and were obtained in all patient groups regardless of angina duration.

Conclusion

TMZ added to other antianginal therapies proved to be effective for reducing angina attacks and short-acting nitrate use, increasing angina-free walking distance, and improving patient well-being in a real-life setting, irrespective of angina duration, including patients with recently diagnosed angina. This provides an opportunity for intensification of treatment early on in the disease process, with the aim of decreasing angina burden and improving patient quality of life.

Safety and dose modification for patients receiving niraparib

Abstract

Background

Niraparib is a poly(ADP-ribose) polymerase (PARP) inhibitor approved in the United States and Europe for maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to platinum-based chemotherapy. In the pivotal ENGOT-OV16/NOVA trial, the dose reduction rate due to TEAE was 68.9%, and the discontinuation rate due to TEAE was 14.7%, including 3.3% due to thrombocytopenia. A retrospective analysis was performed to identify clinical parameters that predict dose reductions.

Patients and methods

All analyses were performed on the safety population, comprising all patients who received at least one dose of study drug. Patients were analyzed according to the study drug consumed (ie, as treated). A predictive modeling method (decision trees) was used to identify important variables for predicting the likelihood of developing grade ≥3 thrombocytopenia within 30 days after the first dose of niraparib and determine cutoff points for chosen variables.

Results

Following dose modification, 200 mg was the most commonly administered dose in the ENGOT-OV16/NOVA trial. Baseline platelet count and baseline body weight were identified as risk factors for increased incidence of grade ≥3 thrombocytopenia. Patients with a baseline body weight <77 kg or a baseline platelet count <150,000/μL in effect received an average daily dose approximating 200 mg (median = 207 mg) due to dose interruption and reduction. Progression-free survival in patients who were dose reduced to either 200 mg or 100 mg was consistent with that of patients who remained at the 300 mg starting dose.

Conclusions

The analysis presented suggests that patients with baseline body weight of < 77 kg or baseline platelets of < 150,000/μL may benefit from a starting dose of 200 mg per day.(ClinicalTrials.gov ID: NCT01847274)

Randomized phase 3 study of docetaxel plus bavituximab in previously treated advanced non-squamous non-small-cell lung cancer

Abstract

Background

Bavituximab is a monoclonal antibody that targets phosphatidylserine in the presence of β₂ glycoprotein 1 (β2GP1) to exert an anti-tumor immune response. This phase 3 trial determined the efficacy of bavituximab combined with docetaxel in patients with previously treated advanced non-small cell lung cancer (NSCLC).

Patients and Methods

Key eligibility criteria included advanced non-squamous NSCLC with disease progression after treatment with platinum-based doublet chemotherapy, evidence of disease control after at least two cycles of first-line therapy, presence of measurable disease, ECOG performance status 0 or 1, adequate bone marrow and organ function, and no recent history of clinically significant bleeding. Eligible patients were randomized 1:1 to receive up to six 21-day cycles of docetaxel plus either weekly bavituximab 3 mg/kg or placebo until progression or toxicity. The primary endpoint was overall survival (OS).

Results

A total of 597 patients were enrolled. Median OS was 10.5 months in the docetaxel + bavituximab arm and was 10.9 months in the docetaxel + placebo arm (HR 1.06; 95% CI, 0.88-1.29; P=0.533). There was no difference in PFS (HR 1.00; 95% CI, 0.82-1.22; P=0.990). Toxicities were manageable and similar between arms. In subset analysis, among patients with high baseline serum β2GP1 levels ≥200 µg/mL, a non-significant OS trend favored the bavituximab arm (HR 0.82; 95% CI 0.63-1.06; P=0.134). Among patients who received post-study immune checkpoint inhibitor therapy, OS favored the bavituximab arm (HR 0.46; 95% CI 0.26-0.81; P=0.006).

Conclusions

The combination of bavituximab plus docetaxel is not superior to docetaxel in patients with previously treated advanced NSCLC. The addition of bavituximab to docetaxel does not meaningfully increase toxicity. The potential benefit of bavituximab observed in patients with high β2GP1 levels and in patients subsequently treated with immune checkpoint inhibitors requires further investigation.NCT01999673

Volvulus with bowel necrosis after laparoscopic appendectomy. Migration of Clip?

Abstract

About 2.8% of patients develop small bowel obstruction, mostly following an open approach appendectomy. Case Report: we present an 18-year-old girl with acute abdomen 10 days following laparoscopic appendectomy. An emergency laparotomy was performed which revealed bowel necrosis and an impacted slipped clip on the mesenterial side of the bowel with signs of bowel strangulation and necrosis. Bowel resection was carried out with primary enteroenteric anastomosis. We suspect the sharp ends of the open clip allowed it to become lodged in the bowel segment resulting in bowel obstruction and subsequent necrosis. It is possible that the clip migrated or was a failed deployment. To our knowledge, this is the first report of mechanical bowel obstruction after laparoscopic appendectomy caused by aberrant surgical clip.
