Evaluation of S201086/GLPG1972, an ADAMTS-5 inhibitor, for the treatment of knee osteoarthritis in ROCCELLA: a phase 2 randomized clinical trial.

Objective: To evaluate the efficacy and safety of the anti-catabolic ADAMTS-5 inhibitor S201086/GLPG1972 for the treatment of symptomatic knee osteoarthritis.

Design: ROCCELLA (NCT03595618) was a randomized, double-blind, placebo-controlled, dose-ranging, phase 2 trial in adults (aged 40-75 years) with knee osteoarthritis. Participants had moderate-to-severe pain in the target knee, Kellgren-Lawrence grade 2 or 3 and Osteoarthritis Research Society International joint space narrowing (grade 1 or 2).

Safety, Pharmacokinetics, and Pharmacodynamics of the ADAMTS-5 Inhibitor GLPG1972/S201086 in Healthy Volunteers and Participants With Osteoarthritis of the Knee or Hip.

GLPG1972/S201086 is a disintegrin and metalloproteinase with thrombospondin motif-5 (ADAMTS-5) inhibitor in development as an osteoarthritis disease-modifying therapy. We report the safety, tolerability, pharmacokinetics, and pharmacodynamics (turnover of plasma/serum ARGS-aggrecan neoepitope fragments [ARGS]) of GLPG1972 in 3 randomized, double-blind, placebo-controlled phase 1 trials. Study A, a first-in-human trial of single (≤2100 mg [fasted] and 300 mg [fed]) and multiple (≤1050 mg once daily [fed]; 14 days) ascending oral (solution) doses, investigated GLPG1972 in healthy men (N = 41; NCT02612246).

The design of a randomized, placebo-controlled, dose-ranging trial to investigate the efficacy and safety of the ADAMTS-5 inhibitor S201086/GLPG1972 in knee osteoarthritis.

Objective: This study aims to assess the efficacy of the anticatabolic 'a disintegrin and metalloproteinase with thrombospondin motif-5' (ADAMTS-5) inhibitor, S201086/GLPG1972, in slowing cartilage loss in participants with knee osteoarthritis (OA).

Design: ROCCELLA (NCT03595618) is a randomized, double-blind, placebo-controlled, parallel-group, dose-ranging, phase 2 trial. We plan to enrol a total of 852 participants with knee OA across 12 countries.

Immunogenicity and estimation of antibody persistence following vaccination with an inactivated virosomal hepatitis A vaccine in adults: A 20-year follow-up study.

Purpose: This was a 20-year follow-up study to assess long-term persistence of protective antibody levels against the hepatitis A virus (HAV) in healthy participants vaccinated with 2 doses of inactivated hepatitis A vaccine (Epaxal®) between 1992 and 1995.

Methods: Blood samples for anti-HAV antibody concentrations were obtained during a follow-up visit 20years after vaccination and were analyzed in parallel with samples still available from previous visits using AxSYM® HAVAB 2.0 assay.

Comparative Efficacy, Safety and Immunogenicity of Hepavax-Gene TF and Engerix-B Recombinant Hepatitis B Vaccines in Neonates in China.

Background: The aim of the study was to compare efficacy, immunogenicity and safety of Hepavax-Gene TF (thimerosal-free) vaccine with comparator in Chinese neonates.

Methods: A double-blind, randomized, parallel-group, stratified study was conducted at multiple sites in China in healthy neonates, consisting of 3 doses of Hepavax-Gene TF or Engerix-B vaccines administered at birth, 1 and 6 months of age, with a 6-month follow-up after vaccination. On the basis of hepatitis B virus (HBV) infection status of mothers, infants were assigned to one of 2 study strata for mothers positive for HBV infection (stratum 1), with or without active replicating virus (substrata 1a, 1b), and for HBV negative mothers (stratum 2).

Lipid metabolism and lipodystrophy in HIV-1-infected patients: the role played by nonnucleoside reverse transcriptase inhibitors.

Dyslipidemia and lipodystrophy represent significant healthcare concerns in HIV-infected patients due to their association with diabetes mellitus and increased cardiovascular disease risk. Since the lipid effects of the nonnucleoside reverse transcriptase inhibitors are not well characterized, we systematically summarized the effects of nonnucleoside reverse transcriptase inhibitor treatment on dyslipidemia and lipodystrophy in HIV-1 infection. As with other classes of antiretroviral agents, the nonnucleoside reverse transcriptase inhibitors are associated with lipid changes, although individual agents exhibit differing effects on lipid profiles.

Vitamin D deficiency in HIV: a shadow on long-term management?

Vitamin D deficiency in HIV infection has attracted much interest. The best known clinical outcomes of vitamin D deficiency are rickets (children) and osteomalacia (adults). Several non-skeletal disorders have also been linked to suboptimal vitamin D levels in the general population.

Lipid levels and changes in body fat distribution in treatment-naive, HIV-1-Infected adults treated with rilpivirine or Efavirenz for 96 weeks in the ECHO and THRIVE trials.

Background: Pooled ECHO/THRIVE lipid and body fat data are presented from the ECHO (Efficacy Comparison in Treatment-Naïve, HIV-Infected Subjects of TMC278 and Efavirenz) and THRIVE (TMC278 Against HIV, in a Once-Daily Regimen Versus Efavirenz) trials.

Methods: We assessed the 96-week effects on lipids, adverse events (AEs), and body fat distribution (dual-energy x-ray absorptiometry) of rilpivirine (RPV) and EFV plus 2 nucleoside/nucleotide reverse transcriptase inhibitors (N[t]RTIs) in treatment-naive adults infected with human immunodeficiency virus type 1 (HIV-1).

Results: Rilpivirine produced minimal changes in total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides.

Change in vitamin D levels and risk of severe vitamin D deficiency over 48 weeks among HIV-1-infected, treatment-naive adults receiving rilpivirine or efavirenz in a Phase III trial (ECHO).

Background: This analysis assessed changes in serum 25-hydroxyvitamin D (25[OH]D; the precursor form of active vitamin D) in antiretroviral-naive adults receiving rilpivirine or efavirenz over 48 weeks in a randomized, double-blind, Phase III trial (ECHO).

Methods: ECHO included 690 patients randomized 1:1 to receive rilpivirine 25 mg once daily (n=346) or efavirenz 600 mg once daily (n=344), plus tenofovir disoproxil fumarate/emtricitabine. 25(OH)D was measured in stored serum samples collected at baseline, and weeks 24 and 48.

Rilpivirine versus efavirenz in HIV-1-infected subjects receiving emtricitabine/tenofovir DF: pooled 96-week data from ECHO and THRIVE Studies.

Objectives: Week 96 efficacy and safety of the non-nucleoside reverse transcriptase inhibitor (NNRTI) rilpivirine (RPV) was compared to efavirenz (EFV) in subset of 1,096 subjects who received emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) in pooled data from 2 phase 3 studies.

Methods: ECHO and THRIVE are double-blind, double-dummy, randomized, active-controlled, non-inferiority phase 3 studies of RPV versus EFV plus 2 NRTIs in antiretroviral-naïve adult subjects. The primary and secondary endpoints were the proportion of subjects with HIV-1 RNA <50 copies/ mL using an intent-to-treat, time to loss of virologic response (ITT-TLOVR) analysis at weeks 48 and 96, respectively.

Multifactorial biological modulation of warm ischemia reperfusion injury in liver transplantation from non-heart-beating donors eliminates primary nonfunction and reduces bile salt toxicity.

Objective: To design a multifactorial biological modulation approach targeting ischemia reperfusion injury to augment viability of porcine liver grafts from non-heart-beating donors (NHBD).

Background Data: Liver Transplantation (LTx) from NHBD is associated with an increased risk of primary nonfunction (PNF) and biliary complications. In porcine NHBD-LTx, we previously reported a 50% risk of PNF and toxic bile formation in grafts exposed to > or =30' warm ischemia (WI).

Selenium deficiency mitigates hypothyroxinemia in iodine-deficient subjects.

Studies were performed to assess the role of combined selenium and iodine deficiency in the etiology of endemic myxedematous cretinism in a population in Zaire. One effect of selenium deficiency may be to lower glutathione peroxidase activity in the thyroid gland, thus allowing hydrogen peroxide produced during thyroid hormone synthesis to be cytotoxic. In selenium-and-iodine-deficient humans, selenium supplementation may aggravate hypothyroidism by stimulating thyroxin metabolism by the selenoenzyme type I iodothyronine 5'-deiodinase.

Neonatal alloimmune thrombocytopenic purpura induced by anti-Bak(a): a case report and review of the literature.

We report a case of neonatal alloimmune thrombocytopenic purpura after an uneventful pregnancy. The baby had systemic purpura at birth and his platelet count was 6 X 10(9)/1. He was treated with maternal platelets and one week later his platelets were normalized.
