Lonapegsomatropin vs Somatropin for Turner Syndrome
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial is testing a new growth hormone treatment for young children with Turner syndrome to help them grow. The new treatment lasts longer in the body, so it doesn't need to be given as frequently. Growth hormone therapy has been used for many years to treat Turner syndrome, showing varied results in improving height.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on hormone replacement therapies for hormone deficiencies other than growth hormone, you must be on stable doses for at least 4 weeks before and during the screening period.
Is Lonapegsomatropin or Somatropin safe for humans?
Studies on Somatropin, including its various forms like Omnitrope and Saizen, show that it is generally safe for humans, with most side effects being mild, such as muscle and joint pain. Serious side effects are rare, and the safety profile is well-documented in both children and adults with growth hormone deficiencies.12345
How does the drug Lonapegsomatropin differ from Somatropin in treating Turner Syndrome?
What data supports the effectiveness of the drug Lonapegsomatropin for Turner Syndrome?
Research shows that various forms of recombinant human growth hormone (like Somatropin and its biosimilars) are effective in increasing height in children with Turner Syndrome. Studies have demonstrated significant improvements in growth rates and other growth-related factors, indicating that these treatments are generally safe and effective for managing short stature in Turner Syndrome.1112131415
