MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The Phase 2, randomized, double-blind, placebo–controlled, multicenter trial was designed to evaluate the efficacy and safety of guselkumab (Tremfya®) compared with placebo in adults with active psoriatic arthritis, despite having received treatment with standard-of-care therapies, including anti-tumor necrosis factor (TNF)-alpha agents.

In an observed analysis presented at ACR 2017, more than 70 percent of patients receiving guselkumab achieved at least a 20 percent improvement in signs and symptoms of disease (ACR 20) at week 56.  Findings also showed that improvements in tender and swollen joints, skin clearance, pain and physical function, and patient-reported quality of life outcomes reported at week 24, were maintained through week 56 in patients receiving guselkumab maintenance therapy (subcutaneous injections every eight weeks).  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The trial explored whether a dual therapy approach of anticoagulation and P2Y12 antagonist – without aspirin – in non-valvular atrial fibrillation (AF) patients following percutaneous coronary intervention (PCI) and stent placement would be as safe, and still efficacious, as the current standard treatment – triple therapy. For more detailed background on the study, readers may want to review the first paragraph of the article in the New England Journal of Medicine.

Results showed significantly lower rates of major or clinically relevant non-major bleeding events for dual therapy with dabigatran, when compared to triple therapy with warfarin.

In the study, the risk for the primary safety endpoint (time to major or clinically relevant non-major bleeding event) was 48 percent lower for dabigatran 110 mg dual therapy and 28 percent lower for dabigatran 150 mg dual therapy (relative difference), with similar rates of overall thromboembolic events.

MedicalResearch.com: What is the background for this study? What are the main findings?

  • The pivotal Phase 3 DRIVE-AHEAD study evaluated the safety and efficacy of a once-daily, single tablet, fixed-dose combination containing doravirine, an investigational non-nucleoside reverse transcriptase inhibitor (NNRTI) for the treatment of HIV-1 infection, compared to a fixed-dose combination containing efavirenz.
    • After 48 weeks of treatment, 84 percent of the 364 treatment-naïve patients taking once-daily DOR/3TC/TDF achieved levels of HIV-1 RNA <50 copies/mL compared to 81 percent of the 364 patients taking once-daily EFV/FTC/TDF, with an estimated treatment difference of 3.5 percent.
    • Increases in mean CD4+ T-cell counts from baseline for the DOR/3TC/TDF and EFV/FTC/TDF groups were 198 and 188 cells/mm3, respectively, with an estimated treatment difference of 10.1.
    • In addition, comparable efficacy was observed across both treatment groups among individuals with high viral load (HIV-1 RNA >100,000 copies/mL) at baseline, which consisted of 69 patients in the DOR/3TC/TDF group and 73 patients in the EFV/FTC/TDF group (Observed Failure approach).
      • Of those patients with a high viral load (HIV-1 RNA >100,000 copies/mL) at baseline, 81 percent in the DOR/3TC/TDF group and 81 percent in the EFV/FTC/TDF group achieved the study’s primary endpoint of <50 copies/mL of HIV-1 RNA, with a treatment difference of 1.0 percent.
    • The study also met its primary safety endpoint, showing that treatment with DOR/3TC/TDF resulted in fewer patients reporting events of several pre-specified neuropsychiatric adverse events compared to EFV/FTC/TDF by Week 48, including dizziness (8.8 percent versus 37.1 percent); sleep disorders and disturbances (12.1 percent versus 25.5 percent); and inability to think clearly or concentrate (4.4 percent versus 8.2 percent).

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The ODYSSEY DM-INSULIN trial was a randomized, double-blind, placebo-controlled, multicenter study that evaluated alirocumab (Praluent) in 517 patients with insulin treated type 1 and type 2 diabetes with high cardiovascular (CV) risk and hypercholesterolemia despite maximally tolerated dose (MTD) statins. The primary endpoint was percent change in calculated LDL-C from baseline to week 24.

Alirocumab 75 mg every two weeks was added to MTD statins, with the dose increased at week 12 to 150 mg every two weeks if the LDL-C at week 8 was greater than or equal to 70 mg/dL. In fact, only about 20% of the alirocumab treated participants required the higher dose.

Results of the type 2 diabetes study population (n=441) showed that the addition of alirocumab to MTD statin therapy, reduced LDL-C by 48.2 percent from baseline compared to a 0.8 percent increase for placebo. The mean difference between the two treatment arms was -49 percent (p<0.0001). Treatment with alirocumab also improved the overall lipid profile. Furthermore, no new safety issues were identified.

There is a large unmet need for improving cholesterol lowering in patients with diabetes. Despite current standard of care, nearly 70 percent of people age 65 or older with diabetes die from some form of heart disease; and 16 percent die of stroke. Additionally, in spite of current standard of care, many people with diabetes continue to have persistent lipid abnormalities resulting in high residual CV risk.

Florence Gressier MD PhD

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Results from recent studies have suggested an increased risk for Autism Spectrum Disorders (ASDs) in children exposed to antidepressants in utero.

We performed a systematic review of and a meta-analysis of published studies to assess the association between ASDs and fetal exposure to antidepressants during pregnancy for each trimester of pregnancy and preconception.

Our systematic review and meta-analysis suggests a significant association between increased ASD risk and maternal use of antidepressants during pregnancy; however, it appears to be more consistent during the preconception period than during each trimester. In addition, the association was weaker when controlled for past maternal mental illness. Maternal psychiatric disorders in treatment before pregnancy rather than antenatal exposure to antidepressants could have a major role in the risk for Autism Spectrum Disorders.

Secukinumab Provides Sustained Improvements in Dermatology-Specific Quality of Life in Moderate to Severe Psoriasis Patients Through 3 Years of Treatment

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Psoriasis is a chronic immune-mediated inflammatory disease that negatively impacts patients’ quality of life (QOL); therefore QOL outcomes are increasingly recognized as an important measure of efficacy in psoriasis, complementing traditional measures of severity such as the Psoriasis Area and Severity Index (PASI).

Secukinumab, a fully human monoclonal antibody that selectively neutralizes interleukin-17A (IL-17A), exhibits significant efficacy in the treatment of moderate-to-severe psoriasis, ankylosing spondylitis and psoriatic arthritis, demonstrating a rapid onset of action and a favorable safety profile.

Biologic therapies for psoriasis have previously been associated with a fall-off in efficacy over time; accordingly, extended follow-up is required to adequately evaluate novel therapeutic strategies like IL-17A inhibition. Recently, results from the extension of the SCULPTURE secukinumab trial showed that high responses initially achieved with secukinumab at year 1 in the SCULPTURE study were sustained over time up to 3 years with no new or unexpected safety concerns. In this analysis, we examined whether the sustained efficacy observed in SCULPTURE up to 3 years was translated into sustained effect of secukinumab on patient’s QOL measured by the Dermatology Life Quality Index (DLQI) questionnaire.

SCULPTURE, a multi-center extension study, was conducted with subjects who completed 52 weeks of treatment. Subjects were randomized into two maintenance dosing regimens; a fixed-interval schedule of secukinumab 300 mg every 4 weeks (Fixed interval dosing regimen (FI) cohort), and secukinumab retreatment-as-needed (Retreatment as needed (RAN) cohort), in which subjects received placebo until start of relapse, at which time secukinumab 300 mg every 4 weeks was re-initiated.

The analysis using as-observed data showed that at Year 3, improvements in the total score on DLQI was well sustained in both FI and RAN cohorts. Approximately two-thirds of the subjects in the FI cohort reported no impact of skin disease on QOL (corresponding to a score of 0 or 1 on DLQI). The proportion of patients in the RAN cohort reporting no impact of the disease on their QOL was well sustained through 3 years but remained consistently lower than those observed in the FI cohort. The results for each subscale of the DLQI questionnaire were consistent with those with DLQI total score i.e. showing high and sustained proportions of patients reporting no impact of the disease on different domains of health-related QOL in the two secukinumab cohorts with greater effect in the FI cohort compared to the RAN cohort.
