Safety and immunogenicity of an investigational maternal trivalent group B streptococcus vaccine in pregnant women and their infants: Results from a randomized placebo-controlled phase II trial.

Background: This study evaluated the safety and immunogenicity of an investigational trivalent group B streptococcus (GBS) vaccine in US pregnant women, transplacental serotype-specific antibody transfer and persistence in infants, and serotype-specific antibodies in breast milk.

Methods: This randomized, observer-blind, placebo-controlled trial administered one dose of trivalent GBS vaccine (n = 49) or placebo (n = 26) to healthy pregnant 18-40-year-old women at 24-34 weeks' gestation. Women were enrolled from March 2014 to August 2015.

Safety and immunogenicity of fully liquid and lyophilized formulations of an investigational trivalent group B streptococcus vaccine in healthy non-pregnant women: Results from a randomized comparative phase II trial.

Background: We evaluated the safety and immunogenicity of liquid and lyophilized formulations of an investigational trivalent group B streptococcus (GBS) vaccine in non-pregnant women and assessed the formulations' equivalence in terms of serotype-specific immune response.

Methods: This phase II, randomized, comparative, observer-blind trial enrolled healthy non-pregnant women 18-40 years of age. Women received a single dose of fully liquid (n = 529) or lyophilized (n = 521) trivalent GBS vaccine on day 1.

Safety and Immunogenicity of a Second Dose of an Investigational Maternal Trivalent Group B Streptococcus Vaccine in Nonpregnant Women 4-6 Years After a First Dose: Results From a Phase 2 Trial.

Background: Maternal immunization against group B streptococcus (GBS) could protect infants from invasive GBS disease. Additional doses in subsequent pregnancies may be needed. We evaluated the safety and immunogenicity of a second dose of an investigational trivalent CRM197-glycoconjugate GBS vaccine (targeting serotypes Ia/Ib/III), administered to nonpregnant women 4-6 years postdose 1.

Recombinant follicle-stimulating hormone (follitropin alfa) for ovulation induction in Japanese patients with anti-estrogen-ineffective oligo- or anovulatory infertility: results of a phase II dose-response study.

Purpose: To determine the optimal regimen of recombinant human follicle-stimulating hormone (r-hFSH) for ovulation induction (OI) in Japanese women with amenorrhea I or anovulatory infertility.

Methods: In this randomized, double-blind, dose-finding study, women aged 20-39 years were enrolled. Patients underwent a chronic low-dose step-up regimen with starting doses of r-hFSH of 37.

Bioequivalence revisited: influence of age and sex on CYP enzymes.

Background And Objective: The activity of cytochrome P450 (CYP) enzymes, which determine the rate of elimination of lipid-soluble drugs, demonstrates considerable interindividual variability. The extent to which age and sex influence CYP activity remains unclear in humans. Our objectives were to determine whether in vivo activity of selected CYP enzymes is affected by age or sex and to evaluate sex bioequivalence in a large sample size.

Coordinated intrahepatic and extrahepatic regulation of cytochrome p4502D6 in healthy subjects and in patients after liver transplantation.

Cytochrome p450 (CYP) 2D6 activity exhibits wide intersubject variation even among individuals with similar genotypes in whom the active enzyme is expressed. There is, therefore, a need to understand the mechanisms involved in determining its activity. The relationship of messenger ribonucleic acid (mRNA) expression to CYP2D6 activity has been evaluated in hepatic and extrahepatic tissues to test the hypothesis of coordinated regulation.
