About PGHD and the Therapeutic Landscape

PGHD is the consequence of inadequate secretion of growth hormone from the pituitary gland in children resulting in low growth hormone (GH) in the body, insufficient production of downstream signaling molecules required for growth, and the subsequent lack of growth. The prevailing standard of care for PGHD consists of a daily injection of exogenous GH administered for approximately 7 years on average. Several once-weekly injectable GH therapies have recently been approved in the US and internationally to treat PGHD. LUM-201, also known as ibutamoren, is an orally administered investigational small molecule that promotes the secretion of GH from the pituitary gland and represents an opportunity for appropriately selected patients to avoid the daily or weekly injections involved with current or forthcoming therapies. LUM-201 has been observed to increase the amplitude of endogenous pulsatile GH secretion, which mimics the natural pattern of GH secretion.
