Monoclonal Antibodies

Romosozumab + Denosumab for Osteoporosis

Phase 2
Led By Adi Cohen, MD
Research Sponsored by Columbia University
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Must agree to use highly effective contraception throughout the period of study drug administration. Highly effective contraception includes methods considered by the CDC to be >99% effective (e.g. vasectomized partner, tubal ligation, hysterectomy, IUD) as well as a combination of barrier method (condoms) with hormonal contraception considered to be > 90% effective (oral contraceptive pill, patch or ring). Systemic progestin only methods (oral or implanted) are not included due to their effect on systemic estrogen levels and thus potential effects on bone health in this premenopausal population.
Premenopausal women, aged 18-48, with regular menses and no historical or biochemical secondary cause of osteoporosis; the lower age limit is to ensure epiphyses are fused, the upper to make it less likely that women will enter menopause during the study. All subjects under age 25 will be screened (bone age radiograph) prior to enrollment to rule out open epiphyses.
Screening 3 weeks
Treatment Varies
Follow Up baseline, 6 month, 12 month, 18 month, 24 month

Study Summary

This trial is testing a new osteoporosis treatment in premenopausal women to see if it is more effective than the current standard of care.

Who is the study for?
This trial is for premenopausal women aged 18-48 with idiopathic osteoporosis, regular menstrual cycles, and no secondary cause of bone loss. Participants must have had low-trauma fractures and a T-score or Z-score ≤ -1.5 at certain bone sites. They should agree to highly effective contraception during the study.Check my eligibility
What is being tested?
The study tests if romosozumab improves bone mass in premenopausal women with osteoporosis better than teriparatide does. It involves giving participants romosozumab monthly for a year followed by denosumab every six months for another year, comparing their results to historical controls.See study design
What are the potential side effects?
Possible side effects include reactions at the injection site, muscle pain, headache, joint pain, and possibly increased risk of heart problems or stroke. There's also a concern about potential harm to bones like unusual fractures.
