5 Warnings and Precautions

5.1 Risk of Osteosarcoma

Additions and/or revisions underlined:

Abaloparatide caused a dose-dependent increase in the incidence of osteosarcoma in male and female rats after subcutaneous administration at exposures 4 to 28 times the human exposure at the clinical dose of 80 mcg [see Nonclinical Toxicology (13.1)].  It is unknown whether TYMLOS will cause osteosarcoma in humans.

Osteosarcoma has been reported in patients treated with a PTH-analog in the post marketing setting; however, an increased risk of osteosarcoma has not been observed in observational studies in humans. There are limited data assessing the risk of osteosarcoma beyond 2 years of TYMLOS and/or use of a PTH-analog [see Dosage and Administration (2.3) and Nonclinical Toxicology (13.1)].

Avoid TYMLOS use in patients with (these patients are at increased baseline risk of osteosarcoma):

  • Open epiphyses (pediatric and young adult patients) (TYMLOS is not approved in pediatric patients) [see Use in Specific Populations (8.4)].

  • Metabolic bone diseases other than osteoporosis, including Paget’s disease of the bone.

  • Bone metastases or a history of skeletal malignancies.

  • Prior external beam or implant radiation therapy involving the skeleton.

  • Hereditary disorders predisposing to osteosarcoma.
