Tymlos Uses, Dosage, Side Effects, Food Interaction and all others data.

Tymlos is an analog of PTHrP (parathyroid hormone-related protein). It was approved in April 28, 2017 by the FDA (as Tymlos) for the treatment of postmenopausal women with osteoporosis at high risk for fracture. Tymlos is a synthetic peptide that is related to hPTHrP and has demonstrated in preclinical testing the potential to widen the anabolic window for bone therapeutics, stimulating bone formation with a limited effect on bone resorption and mineral mobilization. This could enable improved convenience over currently available anabolic therapies, resulting in greater compliance and, ultimately, greater benefit to patients.

Tymlos (BA058), a proprietary analog of human parathyroid hormone-related protein (hPTHrP), is currently undergoing clinical trials by the company for the treatment of osteoporosis in postmenopausal women. PTHrP is a critical peptide for promoting new bone formation, with a distinct role from parathyroid hormone, or PTH, which primarily regulates calcium homeostasis and bone resorption. Clinical studies show increased bone mineral density (BMD) and levels of bone formation markers in a dose-response relationship.

Tymlos is a parathyroid hormone-related protein (PTHrP) analog used for the treatment of osteoporosis in postmenopausal women with a high risk of fracture.

Investigated for use/treatment in postmenopausal osteoporosis to reduce vertebral and/or non-vertebral fractures.

Tymlos is also used to associated treatment for these conditions: High risk of fracture Osteoporosis

How Tymlos works

In target cells, abaloparatide acts as an agonist on PTH type 1 receptor (PTH1R) and activates both G protein–mediated cAMP signaling and β-arrestin-mediated ERK-1/2 signaling pathways with similar potency [A19105]. Tymlos binds to RG conformation of PTH1R with greater selectivity that results in more transient cell signalling responses.


Tymlos has shown to induce higher incidences of osteosarcoma in a dose-dependent manner in a 2 year carcinogenicity study with female and male rats. This correlation is not known to be reflected in humans, however patients with increased risk of osteosarcoma including Paget's disease, open epiphyses, and skeletal malignancies should avoid this treatment. Tymlos may also cause hypercalcemia so should be avoided in patients with pre-existing conditions of primary hyperthyroidism or hypercalcemia. Overdose is commonly associated with hypercalcemia, nausea, vomiting, dizziness, tachycardia, orthostatic hypotension and headache. There is no known antidote for abaloparatide.

Food Interaction

  • Administer vitamin supplements. If dietary intake is inadequate, patients should receive supplemental calcium and vitamin D.
  • Take at the same time every day.
  • Take with or without food.

Volume of Distribution

Vd is approximately 50L.

Elimination Route

The time it takes to reach peak concentration following subcutaneous administration of 80 mcg abaloparatide ranges from 0.25 to 0.52 hr, with the median time of 0.51hr. The bioavailability in healthy women is 36% following administration.

Half Life

The mean (SD) half-life if 1.7 (0.7) hrs.

Elimination Route

Metabolized products are mainly eliminated via renal excretion. Patients with severe renal impairment should be monitored with increased risk of adverse effects however there are no recommended dosage adjustments in patients with mild, moderate or severe renal impairment.
