TYMLOS efficacy was demonstrated in the ACTIVE trial.1,2

IN POSTMENOPAUSAL WOMEN

Study design: A randomized, multicenter, double-blind, placebo- and active-controlled clinical study in postmenopausal women with osteoporosis (N=2,463) aged 49 to 86 years (mean age 69 years) who were randomized to receive TYMLOS 80 mcg (n=824), placebo (n=821), or teriparatide 20 mcg (n=818) subcutaneously once daily for 18 months to assess efficacy and safety of abaloparatide injection.1,2

Primary endpoint: Incidence of new vertebral fracture at 18 months (TYMLOS vs placebo).*1

Secondary endpoints:

  • Incidence of nonvertebral fractures at 18 months (TYMLOS vs placebo and TYMLOS vs teriparatide)†1,2
  • BMD change from baseline at the lumbar spine, total hip, and femoral neck at 18 months (TYMLOS vs placebo; comparisons at 6 and 12 months are exploratory)‡1,2
  • BMD change from baseline at the lumbar spine, total hip, and femoral neck, comparing teriparatide and TYMLOS at 6 months (comparisons at 12 and 18 months are exploratory)‡2

This study was not designed to provide head-to-head comparative efficacy data and cannot be interpreted as evidence of superiority or noninferiority to teriparatide.

IMPORTANT SAFETY INFORMATION

Contraindications: TYMLOS is contraindicated in patients with a history of systemic hypersensitivity to abaloparatide or to any component of the product formulation. Reactions have included anaphylaxis, dyspnea, and urticaria.

Risk of Osteosarcoma: 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 use. Avoid use of TYMLOS for patients at an increased baseline risk for osteosarcoma including patients with open epiphysis (pediatric and young adult patients); 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; or hereditary disorders predisposing to osteosarcoma.

Orthostatic Hypotension: Orthostatic hypotension may occur with TYMLOS, typically within 4 hours of injection. Associated symptoms may include dizziness, palpitations, tachycardia, or nausea, and may resolve by having the patient lie down. For the first several doses, TYMLOS should be administered where the patient can sit or lie down if necessary.

Hypercalcemia: TYMLOS may cause hypercalcemia. TYMLOS is not recommended in patients with pre-existing hypercalcemia or in patients who have an underlying hypercalcemic disorder, such as primary hyperparathyroidism, because of the possibility of exacerbating hypercalcemia.

Hypercalciuria and Urolithiasis: TYMLOS may cause hypercalciuria. It is unknown whether TYMLOS may exacerbate urolithiasis in patients with active or a history of urolithiasis. If active urolithiasis or pre-existing hypercalciuria is suspected, measurement of urinary calcium excretion should be considered.

Pregnancy and Lactation: TYMLOS is not indicated for use in females of reproductive potential.

Adverse Reactions:

  • The most common adverse reactions (incidence ≥2%) reported with TYMLOS in postmenopausal women with osteoporosis are hypercalciuria (11%), dizziness (10%), nausea (8%), headache (8%), palpitations (5%), fatigue (3%), upper abdominal pain (3%), and vertigo (2%).
  • The most common adverse reactions (incidence ≥2%) reported with TYMLOS in men with osteoporosis are injection site erythema (13%), dizziness (9%), arthralgia (7%), injection site swelling (7%), injection site pain (6%), contusion (3%), abdominal distention (3%), diarrhea (3%), nausea (3%), abdominal pain (2%), and bone pain (2%).

INDICATIONS AND USAGE

TYMLOS is indicated for the:

  • treatment of postmenopausal women with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture), or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, TYMLOS reduces the risk of vertebral fractures and nonvertebral fractures.
  • treatment to increase bone density in men with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture), or patients who have failed or are intolerant to other available osteoporosis therapy.
