Background: According to current consensus guidelines for type 2 diabetes management, bodyweight management is as important as attaining glycaemic targets. Retatrutide, a single peptide with agonist activity at the glucose-dependent insulinotropic polypeptide (GIP), GLP-1, and glucagon receptors, showed clinically meaningful glucose-lowering and bodyweight-lowering efficacy in a phase 1 study. We aimed to examine the efficacy and safety of retatrutide in people with type 2 diabetes across a range of doses.

Background: Retatrutide (LY3437943) is an agonist of the glucose-dependent insulinotropic polypeptide, glucagon-like peptide 1, and glucagon receptors. Its dose-response relationships with respect to side effects, safety, and efficacy for the treatment of obesity are not known.

Methods: We conducted a phase 2, double-blind, randomized, placebo-controlled trial involving adults who had a body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) of 30 or higher or who had a BMI of 27 to less than 30 plus at least one weight-related condition.

Background: Treating hyperglycaemia and obesity in individuals with type 2 diabetes using multi-receptor agonists can improve short-term and long-term outcomes. LY3437943 is a single peptide with agonist activity for glucagon, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like peptide 1 (GLP-1) receptors that is currently in development for the treatment of type 2 diabetes and for the treatment of obesity and associated comorbidities. We investigated the safety, pharmacokinetics, and pharmacodynamics of multiple weekly doses of LY3437943 in people with type 2 diabetes in a 12-week study.

The Asian and Latin America Fracture Observational Study (ALAFOS) is a prospective, observational, single-arm study conducted in 20 countries across Asia, Latin America and the Middle East. ALAFOS evaluated new clinical vertebral and non-vertebral fragility fractures in relation to time on teriparatide, in postmenopausal women with osteoporosis in real-life clinical practice. Clinical fragility fractures, back pain, and health-related quality of life (HRQoL) were recorded in 6-month intervals for ≤ 24 months during teriparatide treatment and up to 12-months post-treatment.

Objective: To bridge the efficacy and compare the safety of the 24-week teriparatide treatment in a Chinese osteoporosis study (NCT00414973) to a large international trial (FPT, NCT00670501) to determine whether long-term results from the international study were applicable to Chinese patients.

Methods: In this post-hoc analysis, a propensity score matching method was used to select patients with similar baseline characteristics. Patients were female with osteoporosis at high risk of fracture, aged ≥55 years, and had no history of rheumatoid arthritis or corticosteroid use.

Objective: To describe the study design and baseline patient characteristics of the Asia and Latin America Fracture Observational Study (ALAFOS) to better understand the profile of patients receiving teriparatide during the course of routine clinical practice in Asia, Latin America, the Middle East and Russia.

Methods: Prospective, observational, non-interventional study in postmenopausal women with osteoporosis who are prescribed teriparatide for up to 24 months, according to local medical standards, with a 12 month post-treatment follow-up.

Measures: Demographics, risk factors for osteoporosis and fractures, history of fracture, prior osteoporosis medications, comorbidities, physical function, back pain and quality of life (QoL).

Objective: We undertook this phase III study to evaluate baricitinib, an orally administered JAK-1/JAK-2 inhibitor, as monotherapy or combined with methotrexate (MTX) compared to MTX monotherapy in patients with active rheumatoid arthritis (RA) who had received no or minimal conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and who were naive to biologic DMARDs.

Methods: A total of 588 patients were randomized 4:3:4 to receive MTX monotherapy (once weekly), baricitinib monotherapy (4 mg once daily), or the combination of baricitinib and MTX for 52 weeks. The primary end point assessment was a noninferiority comparison of baricitinib monotherapy to MTX monotherapy based on the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 24.

Article Synopsis
  • A study was conducted on 119 Indian patients with severe osteoporosis undergoing treatment with teriparatide or antiresorptives to assess back pain over a year.
  • Participants were evaluated at baseline, 6-months, and 12-months using various questionnaires to measure back pain incidence and severity.
  • Results showed that teriparatide-treated patients had a similar risk of new/worsening back pain compared to antiresorptive-treated patients, with a significantly lower incidence of severe back pain and higher satisfaction rates after 6 months.

Background: Phosphodiesterase type 5 (PDE5) inhibitors have discontinuation rates as high as 60% in men with erectile dysfunction. Treatment satisfaction has been significantly associated with treatment continuation. Understanding key characteristics in terms of treatment preference, relationship, and lifestyle issues could provide direction on how to improve compliance with PDE5 inhibitor treatment globally.

Background: Erectile dysfunction (ED) negatively impacts quality of life. Phosphodiesterase type 5 inhibitors (PDE5Is) are effective in treating ED; however, rates of discontinuation remain high.

Objectives: To assess on-demand PDE5I treatment persistence and adherence through 6 months in Middle Eastern and North African (MENA) men with ED in a prospective, non-interventional, observational trial.
