Introduction
Serostim LQ, a recombinant human growth hormone (somatropin), is used primarily for the treatment of HIV-associated wasting or cachexia. Here, we will delve into the clinical trials, market analysis, and future projections for this drug.
Clinical Trials Overview
Efficacy in HIV-Associated Wasting
Clinical trials have demonstrated the efficacy of Serostim LQ in treating HIV-associated wasting. In two placebo-controlled trials, Serostim LQ showed statistically significant increases in lean body mass (LBM), body weight, and improvements in physical endurance[4][5].
- Trial Design: These trials were 12-week, randomized, double-blind, and placebo-controlled, followed by an open-label extension phase. Patients received either placebo or Serostim LQ at doses of approximately 0.1 mg/kg daily or every other day[4][5].
- Outcomes: The trials revealed that Serostim LQ increased LBM and body weight significantly compared to the placebo group. For instance, after 12 weeks, the mean difference in weight increase was 1.6 kg (3.5 lb), and the mean difference in LBM change was 3.1 kg (6.8 lbs) between the Serostim LQ-treated group and the placebo group[5].
- Physical Endurance: Treadmill exercise testing showed a median increase in work output by 13% in the Serostim LQ-treated group, indicating improved physical function[5].
Adverse Reactions
Common adverse reactions associated with Serostim LQ include edema, arthralgia, pain in extremity, hypoesthesia, myalgia, and increased blood glucose levels. These symptoms often subsided with dose reduction[1][3].
- Hyperglycemia and Diabetes: The incidence of hyperglycemia was reported in 3.6% of the placebo group, 1.9% of the 0.1 mg/kg every other day group, and 3.2% of the 0.1 mg/kg daily group. One case of diabetes mellitus was noted in the daily dose group during the first 12 weeks, and additional cases were reported during the extension phase[1][3].
