Safety and immunogenicity of a SARS-CoV-2 Gamma variant RBD-based protein adjuvanted vaccine used as booster in healthy adults.

A Gamma Variant RBD-based aluminum hydroxide adjuvanted vaccine called ARVAC CG was selected for a first in human clinical trial. Healthy male and female participants (18-55 years old) with a complete COVID-19-primary vaccine scheme were assigned to receive two intramuscular doses of either a low-dose or a high-dose of ARVAC CG. The primary endpoint was safety.

Pharmacokinetics of a new fixed-dose combination of candesartan cilexetil, hydrochlorothiazide, and rosuvastatin in healthy adult subjects.

Background: A fixed-dose combination (FDC) of candesartan cilexetil, hydrochlorothiazide and rosuvastatin (CC/HCTZ/RSV) has been developed to enhance patient compliance in the primary prevention of cardiovascular diseases.

Objective: To evaluate if the combination of the product components in the new FDC capsule formulation affects their respective pharmacokinetic and in vitro dissolution patterns.

Materials And Methods: In vitro dissolution profiles were compared in USP-43 and in biorelevant dissolution media.

Clinical investigation of the biopharmaceutical characteristics of nifurtimox tablets - Implications for quality control and application.

Nifurtimox is approved in Chagas disease and has been used in endemic countries since the 1960s. Nifurtimox, available as a 120 mg tablet, is administered with food typically three times daily, and dose is adjusted for age and bodyweight. Accurately or reproducibly fragmenting the 120 mg tablet for dose adjustment in young children and those with low bodyweight is problematic.

Drug-Drug Interaction Study of Benznidazole and E1224 in Healthy Male Volunteers.

E1224 is a prodrug of ravuconazole (RVZ), an antifungal drug with promising anti- activity, the causative organism of Chagas disease (CD). This study was designed to assess the pharmacokinetics (PK) and safety interactions of benznidazole (BNZ), the drug of choice for treatment of CD, and E1224 in healthy volunteers. This open-label, single-center, sequential, single- and multiple-oral-dose study enrolled 28 healthy male subjects.

Biopharmaceutical Characteristics of Nifurtimox Tablets for Age- and Body Weight-Adjusted Dosing in Patients With Chagas Disease.

Treatment of Chagas disease with nifurtimox requires age- and body weight-adjusted dosing, resulting in complex dosing instructions. Appropriate formulations are needed for precise and compliant dosing, especially in pediatric patients. We characterized the biopharmaceutical features of a standard nifurtimox 120-mg tablet and a 30-mg tablet developed to improve dose accuracy.

Bioequivalence study of two oral tablet formulations containing saquinavir mesylate boosted with ritonavir in healthy male subjects.

Saquinavir (SAQ) mesylate (CAS 149845-06-7) is a potent inhibitor of the HIV-1 protease indicated in combination with other antiretrovirals for the management of HIV-1 infection. The objective of this study was to compare rate and extent of absorption and to assess the bioequivalence between a new pharmaceutical equivalent tablet formulation containing 500 mg of SAQ mesylate and the innovator film coated tablet formulation. A randomized, single-center, open-label, two-treatment, two-sequence, three-period, replicated crossover bioequivalence study in 40 healthy male subjects was conducted.

Bioequivalence study of two oral tablet formulations containing tenofovir disoproxil fumarate in healthy volunteers.

Tenofovir disoproxil fumarate (TDF, CAS 147127-20-6) is a nucleotide reverse transcriptase inhibitor which is indicated in combination with other antiretroviral agents for the management of HIV-1 infection. The objective of this study was to compare the rate and extent of absorption and to assess the bioequivalence between a new pharmaceutical equivalent tablet formulation containing 300 mg of TDF and the innovator product. A randomized, single-center, open-label, single-dose, two-way crossover bioequivalence study in 40 healthy adult subjects was conducted.
