FDA approved Prolia (denosumab) for Osteoporosis and Bone Loss in Multiple SettingsFDA approved new drug Prolia for osteoporosis and bone loss

Key Takeaway
Consider Prolia for high-risk osteoporosis patients who have failed or are intolerant to other therapies.

The FDA has approved Prolia (denosumab), a RANK ligand inhibitor, for the treatment of osteoporosis and bone loss in several patient populations. The drug is indicated for postmenopausal women with osteoporosis at high risk for fracture, men with osteoporosis, glucocorticoid-induced osteoporosis in men and women, and to increase bone mass in men receiving androgen deprivation therapy for nonmetastatic prostate cancer and women receiving adjuvant aromatase inhibitor therapy for breast cancer. Prolia reduces the incidence of vertebral, nonvertebral, and hip fractures in postmenopausal women and vertebral fractures in men on ADT. The approval provides a new option for patients at high risk who have failed or are intolerant to other therapies.

Clinical Details (Mechanism · Dosing · Trial Data · Warnings)
Mechanism of Action

Prolia is a RANK ligand (RANKL) inhibitor. It binds to RANKL, preventing activation of osteoclasts and reducing bone resorption.

Indication & Patient Population

Prolia is indicated for: treatment of postmenopausal women with osteoporosis at high risk for fracture (history of osteoporotic fracture, multiple risk factors, or failed/intolerant to other therapy); to increase bone mass in men with osteoporosis at high risk for fracture; treatment of glucocorticoid-induced osteoporosis in men and women at high risk for fracture who are on systemic glucocorticoids ≥7.5 mg prednisone daily for ≥6 months; to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy for nonmetastatic prostate cancer; to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer.

Dosing & Administration

Prolia is administered by a healthcare provider as a 60 mg subcutaneous injection every 6 months in the upper arm, upper thigh, or abdomen. Patients should take calcium 1000 mg daily and at least 400 IU vitamin D daily. Pregnancy must be ruled out prior to administration. In patients with advanced CKD (eGFR <30 mL/min/1.73 m2), evaluate for CKD-MBD with iPTH, serum calcium, 25(OH) vitamin D, and 1,25(OH)2 vitamin D before treatment.

Key Clinical Trial Data

Trial data not available in label.

Warnings & Contraindications

Prolia can cause fetal harm based on animal studies. Pregnancy testing is required in females of reproductive potential. In patients with advanced CKD, evaluate for CKD-MBD before treatment.

Place in Therapy

Prolia is indicated for patients at high risk for fracture, including those who have failed or are intolerant to other osteoporosis therapies. It reduces vertebral, nonvertebral, and hip fractures in postmenopausal women and vertebral fractures in men on ADT.

The FDA has approved a new drug called Prolia (denosumab) to help treat osteoporosis and bone loss. Osteoporosis is a condition that makes bones weak and more likely to break. Prolia works by blocking a protein that causes bone breakdown, helping to keep bones stronger.

Prolia is for several groups of people. These include postmenopausal women with osteoporosis who are at high risk for fractures, men with osteoporosis, and people who have bone loss caused by taking steroid medicines. It is also for men and women who are on certain hormone treatments for prostate or breast cancer that can lead to bone loss.

This approval means there is a new treatment option for people who have not done well with other therapies or cannot take them. In studies, Prolia lowered the chance of spine, hip, and other fractures. However, like all medicines, it has possible side effects and is not right for everyone.

If you think Prolia might be for you, talk to your doctor. Your doctor can help decide if this drug is a good fit based on your health history and needs. This news is encouraging, but it is important to make treatment decisions with your healthcare team.

What this means for you:
Prolia is a new FDA approved option for osteoporosis and bone loss; talk to your doctor to see if it is right for you.

1 INDICATIONS AND USAGE Prolia is a RANK ligand (RANKL) inhibitor indicated for treatment: of postmenopausal women with osteoporosis at high risk for fracture ( 1.1 ) to increase bone mass in men with osteoporosis at high risk for fracture ( 1.2 ) of glucocorticoid-induced osteoporosis in men and women at high risk for fracture ( 1.3 ) to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy for nonmetastatic prostate cancer ( 1.4 ) to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer ( 1.5 ) 1.1 Treatment of Postmenopausal Women with Osteoporosis at High Risk for Fracture Prolia 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, Prolia reduces the incidence of vertebral, nonvertebral, and hip fractures [see Clinical Studies (14.1) ] . 1.2 Treatment to Increase Bone Mass in Men with Osteoporosis Prolia is indicated for treatment to increase bone mass 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 [see Clinical Studies (14.2) ] . 1.3 Treatment of Glucocorticoid-Induced Osteoporosis Prolia is indicated for the treatment of glucocorticoid-induced osteoporosis in men and women at high risk of fracture who are either initiating or continuing systemic glucocorticoids in a daily dosage equivalent to 7.5 mg or greater of prednisone and expected to remain on glucocorticoids for at least 6 months. High risk of fracture is defined as a history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy [see Clinical Studies (14.3) ] . 1.4 Treatment of Bone Loss in Men Receiving Androgen Deprivation Therapy for Prostate Cancer Prolia is indicated as a treatment to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy (ADT) for nonmetastatic prostate cancer. In these patients Prolia also reduced the incidence of vertebral fractures [see Clinical Studies (14.4) ] . 1.5 Treatment of Bone Loss in Women Receiving Adjuvant Aromatase Inhibitor Therapy for Breast Cancer Prolia is indicated as a treatment to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer [see Clinical Studies (14.5) ] .
