Semparatide (previously known as RS-66271) was developed as an analog of parathyroid hormone-related protein (PTHrP) with shortening the time for fracture healing. Experiments on animals have shown that this compound was an effective therapy for preventing impaired bone healing caused by prednisone. Clinical trials with postmenopausal osteoporotic women have revealed that semparatide cause sustained increases in the spine. However, further, development appears to have been discontinued by Roche.
