About This Trial

The purpose of this research is to identify strategies that minimize bone loss that occurs when older adults lose weight. Participation in this research will involve up to nine assessment visits and last up to two years.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

A target enrollment of 900 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Treatments Being Tested

DRUG

Bisphosphonate

Medicine used to treat bone problems, called osteopenia or osteoporosis.

BEHAVIORAL

Resistance Training/Bone-Loading Exercise

Exercise in small groups three days per week under the supervision of exercise physiologists. Heart rate and blood pressure will be measured before and after each session and participants will warm-up by walking or cycling for five minutes at a slow pace. All RT exercises will be conducted on machines which accommodate different body sizes and allow small increments in resistance, both important considerations for low functioning older adults with obesity.

OTHER

Placebo

Capsules identical to the active alendronate capsules without any active ingredients with the same dosing and follow up as BIS treatment group.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
