The purpose of this study is to estimate the pharmacokinetics (PK) of 3 different modified-release formulations of lersivirine and compare it to the PK of the immediate-release tablet. The effect of food on the PK of one of the modified-release tablets will also be assess along with the safety and tolerability of each treatment.

Two-year Carcinogenicity Study in Rats with a Nonnucleoside Reverse Transcriptase Inhibitor

Article

Author: Nambiar, Prashant R. ; Bailey, Steven A. ; Houle, Christopher ; Morton, Daniel ; Finch, Gregory L. ; Thomford, Peter J. ; Dochterman, Leland Wayne ; Fate, Gwendolyn

Administration of lersivirine, a nonnucleotide reverse transcriptase inhibitor, daily by oral gavage to Sprague-Dawley rats for up to 2 yr was associated with decreased survival, decreased body weights, and an increase in neoplasms and related proliferative lesions in the liver, thyroid, kidney, and urinary bladder. Thyroid follicular adenoma and carcinoma, the associated thyroid follicular hypertrophy/hyperplasia, hepatocellular adenoma/adenocarcinoma, altered cell foci, and hepatocellular hypertrophy were consistent with lersivirine-related induction of hepatic microsomal enzymes. Renal tubular adenoma and renal tubular hyperplasia were attributed to the lersivirine-related exacerbation of chronic progressive nephropathy (CPN), while urinary bladder hyperplasia and transitional cell carcinoma in the renal pelvis and urinary bladder were attributed to urinary calculi. Renal tubular neoplasms associated with increased incidence and severity of CPN, neoplasms of transitional epithelium attributed to crystalluria, and thyroid follicular and hepatocellular neoplasms related to hepatic enzyme induction have low relevance for human risk assessment.

Mild Palladium-Catalyzed Cyanation of (Hetero)aryl Halides and Triflates in Aqueous Media

Q1 · CHEMISTRY

Article

Author: Cohen, Daniel T. ; Buchwald, Stephen L.

A mild, efficient, and low-temperature palladium-catalyzed cyanation of (hetero)aryl halides and triflates is reported. Previous palladium-catalyzed cyanations of (hetero)aryl halides have required higher temperatures to achieve good catalytic activity. This current reaction allows the cyanation of a general scope of (hetero)aryl halides and triflates at 2-5 mol % catalyst loadings with temperatures ranging from rt to 40 °C. This mild method was applied to the synthesis of lersivirine, a reverse transcriptase inhibitor.

Single‐dose pharmacokinetics, safety, and tolerability of modified‐release formulations of lersivirine in healthy subjects

Article

Author: Wang, Cunshan ; Heera, Jayvant ; Mukwaya, Geoffrey ; Wang, Ronnie ; Mendes da Costa, Laure ; Vourvahis, Manoli ; Tawadrous, Margaret ; Weatherley, Barry

This article identifies a MR lersivirine formulation with a lower C_max than the IR formulation but with comparable total plasma exposures (AUC).Modified-release (MR) lersivirine was associated with good tolerability among the small number of healthy subjects were discussed in this article.
