Treatment Results
In clinical trials, Serostim® increased lean body mass and body weight, and improved physical endurance
2 clinical trials tested the effects of Serostim® on lean body mass (LBM), body weight, and physical endurance. All study participants also received antiretroviral therapy during the course of the trials.
Clinical Trial 1
Study design
In Clinical Trial 1, Serostim® was studied in 178 participants living with HIV and diagnosed with HIV‑associated wasting. Participants received placebo for 12 weeks or Serostim® daily. Some participants continued on treatment for another 12 weeks, for a total of 24 weeks.
Results
Participants diagnosed with HIV‑associated wasting and treated with Serostim® daily for 12 weeks experienced:
An average increase of
6.80 pounds (3.10 kilograms) more LBM
compared with those in
the placebo group
An average increase of
3.50 pounds (1.60 kilograms) more weight
compared with those in
the placebo group
Results at 12 weeks were evaluated in 70 participants treated with Serostim® and 71 participants who received placebo.
During the additional 12 weeks of the study, participants on Serostim® had no significant changes and maintained the increases in LBM and total body weight.
At 12 weeks of treatment, participants taking Serostim® significantly improved their physical endurance as measured by treadmill exercise.
Clinical Trial 2
Study design
Results
After 12 weeks of treatment:
The placebo-treated group of 222 participants experienced an average increase of 2.13 pounds (0.97 kilograms) in LBM and 1.52 pounds (0.69 kilograms) in total weight body weight
230 participants treated with Serostim® every other day experienced an average increase of 8.56 pounds (3.89 kilograms) in LBM and 4.80 pounds (2.18 kilograms) in total body weight
218 participants treated with Serostim® daily experienced an average increase of 12.85 pounds (5.84 kilograms) in LBM and 6.14 pounds (2.79 kilograms) in total body weight
The average increases in LBM and total body weight were significantly greater in both Serostim® treatment groups compared with the placebo group after 12 weeks of treatment.
A total of 646 participants completed the 12-week study and continued on Serostim® treatment for an additional 12 weeks. 548 of these participants completed the additional 12 weeks of treatment. These participants maintained their increases in LBM and total body weight.
Participants taking Serostim® significantly improved their physical endurance as measured by a stationary bike exercise after 12 weeks of treatment. On average:
222 participants who were given a placebo had an average 0.2% decrease in their physical endurance
230 participants who received Serostim® every other day increased physical endurance by 8.9%
A total of 646 participants completed the 12-week study and continued on Serostim® treatment for an additional 12 weeks. 548 of these participants completed an additional 12 weeks of active treatment. Participants continuing on Serostim® treatment maintained or improved their physical endurance throughout the study extension period.
Patients’ perceptions of the impact of 12 weeks of treatment on their wasting symptoms as assessed by the Bristol-Meyers Anorexia/Cachexia Recovery Instrument improved with both doses of Serostim® in Clinical Trial 2.
