US-based Concert Pharmaceuticals is developing a drug called CTP-543 that has been touted as a miracle drug for hair growth. What is the truth? Can it control hair loss? Can it help people with genetic baldness?
In this article based on his educational video, Dr. John Watts — dermatologist, trichologist and hair transplant surgeon in Hyderabad with over 1,900 transplant procedures — separates the facts from the hype.
What CTP-543 actually is
Concert Pharmaceuticals states that the ongoing clinical trials for the oral drug CTP-543 are solely meant to evaluate it as a potential treatment for alopecia areata.
Alopecia areata is an autoimmune disease in which the body's immune system attacks the person's own hair, resulting in patchy or complete hair loss.
How it works
CTP-543 acts as a Janus kinase (JAK) inhibitor. “The JAK enzymes play an important role whose improper or abnormal behaviour triggers alopecia areata, causing permanent damage to the hair if not treated early. This drug will inhibit the release of this enzyme and control it,” explains Dr. John Watts.
The types of alopecia areata it may treat
“If alopecia areata is localised, the damaged area can be like a coin shape. If the entire scalp is affected, we term it Alopecia Totalis, and if the entire face — moustache, scalp and beard — is affected, we call it Alopecia Universalis,” informs Dr. John.
What it will NOT do
This is the key point: nowhere does Concert Pharmaceuticals mention in the scientific literature that CTP-543 works for the treatment of general hair loss or hereditary baldness. “This drug seems to be only for the treatment of alopecia areata,” Dr. Watts clarifies.
If your hair loss is androgenetic (genetic pattern baldness), CTP-543 is not the miracle you may have read about — the established treatment options for pattern baldness remain a separate conversation with your dermatologist.
