The World Health Organization recommendation on the use of single low-dose primaquine (SLD-PQ) to reduce Plasmodium falciparum malaria transmission requires more safety data.
Our laboratory received segments of umbilical cord that originated from identical twins for routine toxicology analysis. The specimens were analyzed multiple times by liquid chromatography tandem mass spectrometry. The umbilical cord from newborn #1 was positive for hydromorphone only (1.06 ng/g), and the umbilical cord from newborn #2 was positive for hydromorphone (0.81 ng/g) and benzoylecgonine (5.41 ng/g). The hydromorphone results are consistent with maternal administration of hydromorphone; however, t...
Faldaprevir (FDV) is a potent, orally administered inhibitor of hepatitis C virus. In this single-centre, open-label, fixed-sequence, cross-over study of 32 healthy adult male and female volunteers, subjects received either a single dose of cyclosporine (CsA) 50 mg (N=16) or tacrolimus (TAC) 0.5 mg (N=16), followed by a washout of at least 14 days. Each subject then received a loading dose of FDV 240 mg followed by 120 mg FDV once daily for 6 days. FDV 120 mg was then co-administered with an additional sing...
Several studies demonstrated that placebo treatment may have a significant impact on many different symptoms. While in the traditional view concealment of the placebo is essential, recent studies report intriguing evidence that placebos may work even without deception. For example, it has been demonstrated that open-label placebos can improve symptoms in allergic rhinitis. However, the mechanisms of how placebos without concealment work remain unknown.
Taselisib is a potent and selective phosphatidylinositide 3-kinase (PI3K) inhibitor. This paper reports the first study of taselisib administration in Japanese patients. The aim of this two-stage, phase I, multicenter, open-label, dose-escalation study was to evaluate the safety, pharmacokinetics, and preliminary efficacy of taselisib as monotherapy in Japanese patients with advanced solid tumors (Stage 1), and as part of combination therapy in Japanese patients with hormone receptor (HR)-positive locally a...
Previous meta-analyses have shown paradoxical increased risk of bleeding and thrombotic events in patients receiving antiangiogenics (AA) that may be simply explained by the studies design included. By a meta-epidemiological approach, we aim to investigate the impact of double-blind (DB) and open-label study designs on the risks of bleeding, venous thrombotic events (VTE) and arterial thrombotic events (ATE) in cancer patients treated with AA.
To improve room temperature stability and oral bioavailability of mavatrep (JNJ-39439335, a transient receptor potential vanilloid subtype-1 antagonist), various formulations were initially developed and evaluated in 2 phase 1 open-label, randomized, 3-way crossover studies in healthy participants. Study 1 evaluated 2 new overencapsulated tablet formulations (formulations B and C) relative to an overencapsulated early tablet formulation (formulation A), using mavatrep HCl salt form. Because these tablets we...
