Concentrations of Raltegravir in the Semen of HIV-Infected Men

2014-08-27 03:16:47 | BioPortfolio


The objective of this study is to determine if concentrations of raltegravir in semen exceed the 50% and 95% inhibitory concentrations of HIV during the dose interval.

The secondary objective is to determine the extend of raltegravir penetration into semen by obtaining semen to plasma ratios across the dosing interval, to determine the area under the concentration time curve of raltegravir in semen, and to determine the variability in the penetration of raltegravir into the seminal compartment over the dosing period.


The patient population will consist of 12 male HIV-positive patients who have been receiving stable antiretroviral therapy that includes raltegravir for a minimum of three months. Patients will be enrolled from one clinic in downtown Toronto and a hospital affiliated HIV specialty clinic in Ottawa, Ontario. Eligible patients will have evidence of full virologic suppression (HIV viral load < 50 copies/mL) at least one month prior to enrollment in the study. No changes will be made to the patients antiretroviral therapy during the course of the study.

Medical and Biotech [MESH] Definitions

The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.

A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.

The process by which semen is kept viable outside of the organism from which it was derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).

A condition of suboptimal concentration of SPERMATOZOA in the ejaculated SEMEN to ensure successful FERTILIZATION of an OVUM. In humans, oligospermia is defined as a sperm count below 20 million per milliliter semen.

A condition of having no sperm present in the ejaculate (SEMEN).
