To obtain data on the safety of administering megestrol acetate and dronabinol as single agents or in combination to patients with human immunodeficiency virus (HIV)-wasting syndrome. To obtain preliminary data on the efficacy of single agent and combination therapy with megestrol acetate and dronabinol with regard to weight gain, appetite increase and quality of life in this patient population. To obtain steady-state pharmacokinetics data when megestrol acetate and dronabinol are administered as single agents and in combination. HIV-wasting syndrome, which is characterized by severely debilitating anorexia and weight loss, is of particular concern because it can exacerbate the primary illness and is associated with a poor prognosis. Attempts at maintaining body mass through the use of megestrol acetate and dronabinol, two anti-cachectic drugs, may prolong survival.

HIV-wasting syndrome, which is characterized by severely debilitating anorexia and weight loss, is of particular concern because it can exacerbate the primary illness and is associated with a poor prognosis. Attempts at maintaining body mass through the use of megestrol acetate and dronabinol, two anti-cachectic drugs, may prolong survival.

Fifty-six patients are randomized to one of four treatment arms, as follows: high-dose megestrol acetate alone; dronabinol alone; high-dose megestrol acetate combined with dronabinol; or low-dose megestrol acetate combined with dronabinol. Treatment continues for 12 weeks. Patients are evaluated for toxicity, preliminary evidence of response (e.g., weight gain), and steady-state pharmacokinetics of drug therapies.

Ages Eligible for Study:  18 Years and above,  Genders Eligible for Study:  Both

Criteria
