Phoenix IVIVC Toolkit

The Phoenix IVIVC Toolkit provides enhanced tools for in vitro-in vivo correlation studies used by formulation and pharmaceutical scientists to improve the success of BE studies. The IVIVC Toolkit approach requires less assumptions, as compared to other methods, and helps the user define the correlation observed from real in vivo profiles as compared to the dissolution profiles.

Supporting Development of a New Antibacterial Drug

In recent years, proliferation of plasmids encoding extended-spectrum β-lactamases (ESBLs) has fueled the rise of multi-drug resistant Gram-negative bacterial infections. Avibactam inhibits class A and C serine β-lactamases, including KPC carbapenemases. While avibactam itself is not bactericidal, it restores the effectiveness of β-lactam antibiotics, including ceftazidime, against ESBL-producing pathogens. The sponsor sought to combine avibactam […]

Pharmacokinetic profile of defibrotide in patients with renal impairment.

Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable, potentially life-threatening complication of hematopoietic stem cell transplant conditioning. Severe VOD/SOS, generally associated with multiorgan dysfunction (pulmonary or renal dysfunction), may be associated with >80% mortality. Defibrotide, recently approved in the US, has demonstrated efficacy treating hepatic VOD/SOS with multiorgan dysfunction. Because renal […]

Safety and pharmacokinetics of single and multiple ascending doses of avibactam alone and in combination with ceftazidime in healthy male volunteers: results of two randomized, placebo-controlled studies.

Avibactam is a novel non-β-lactam β-lactamase inhibitor effective against Ambler class A, C and some class D β-lactamases that is currently in clinical development in combination with ceftazidime for the treatment of serious Gram-negative infections. It restores the in vitro activity of a range of β-lactams, including ceftazidime, against extended-spectrum β-lactamase-producing pathogens. Two phase I […]

Effect of age and sex on the pharmacokinetics and safety of avibactam in healthy volunteers

Avibactam is a novel non-β-lactam β-lactamase inhibitor currently being assessed in combination with ceftazidime, ceftaroline fosamil, and aztreonam. The objectives of this study were to investigate the pharmacokinetics, safety, and tolerability of avibactam in healthy young (aged 18-45 years) and elderly (aged ≥65 years) volunteers of both sexes. This was a Phase I, open-label study […]

Population pharmacokinetic analysis of axitinib in healthy volunteers.

Axitinib is a potent and selective second generation inhibitor of vascular endothelial growth factor receptors 1, 2 and 3 approved for second line treatment of advanced renal cell carcinoma. The objectives of this analysis were to assess plasma pharmacokinetics and identify covariates that may explain variability in axitinib disposition following single dose administration in healthy […]

Axitinib in metastatic renal cell carcinoma: results of a pharmacokinetic and pharmacodynamic analysis.

Axitinib is a potent and selective inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, approved for second-line therapy for advanced renal cell carcinoma (RCC). Axitinib population pharmacokinetic and pharmacokinetic/pharmacodynamic relationships were evaluated. Using nonlinear mixed effects modeling with pooled data from 383 healthy volunteers, 181 patients with metastatic RCC, and 26 patients […]

Pharmacokinetics of Tramadol and O-Desmethyltramadol Enantiomers Following Administration of Extended-Release Tablets to Elderly and Young Subjects.

Tramadol is frequently used in geriatric patients; however, pharmacokinetic (PK) publications on tramadol and O-desmethyltramadol (ODM) in elderly patients are rare. Our objective was to characterize the PK of tramadol and ODM, including absorption processes and covariates for tramadol, in elderly and young subjects after single-dose administration of 200-mg extended-release tablets. We conducted a PK […]

Population pharmacokinetic modeling of motesanib and its active metabolite, M4, in cancer patients.

Motesanib is a small molecule and potent multikinase inhibitor with antiangiogenic and antitumor activity. Population pharmacokinetic (POPPK) modeling of motesanib and M4, an active metabolite, was performed to assess sources of variability in cancer patients. The analysis included data collected from 451 patients from 8 clinical trials with oral doses of motesanib ranging from 25 […]
