Osteoporosis clinical trials at UC Health

4 in progress, 1 open to eligible people

Showing trials for
  • Trial of Parkinson's And Zoledronic Acid

    open to eligible people ages 65 years and up

    This home-based study is a randomized (1:1) placebo-controlled trial of a single infusion of zoledronic acid-5 mg (ZA) for the prevention of fractures in men and women aged 65 years and older with Parkinson's disease and parkinsonism with 2 years of follow-up. A total of 3500 participants will be enrolled and randomized in the United States. Participants, follow-up outcome assessors, and study investigators will be blinded to assigned study treatment. This trial is funded by the National Institute of Aging.

  • Novel Combination Therapy for Osteoporosis in Men

    Sorry, in progress, not accepting new patients

    Osteoporotic fractures are a key health problem in older men. Although there are drugs approved to treat osteoporosis in men [bisphosphonates, denosumab, and teriparatide (TPTD) or PTH(1-34)], there is a lack of knowledge on how to use them effectively. TPTD is a potent bone anabolic drug, meaning that it builds bone mass. However, doctors do not know if it should only be used as single drug or whether it can be more effectively combined to achieve the most benefit? This trial will test a novel combination therapy for osteoporosis in men based on exciting laboratory findings in mice. TPTD works to raise bone mass and improve bone strength by stimulating PTH receptors (PTH-Rs) on the membranes of bone-forming cells or osteoblasts (OBs). Calcimimetics are drugs that activate calcium receptors (CaSRs) in OBs. CaSRs in OBs participate in new bone formation. Daily injections of TPTD, given along with a calcimimetic drug (called NPS-R568), over 6 weeks markedly improved bone mineral density (BMD) and structure in mice. This study will test whether the combined activation of PTH-Rs and CaSRs (by the combination treatment of TPTD+calcimimetic cinacalcet) in men will produce greater bone forming responses than PTH-R activation alone (TPTD+placebo). The study has two aims and will be done in 48 men with low bone mass: (1) to determine the effects of 11 months treatment with TPTD+cinacalcet vs TPTD+placebo on BMD and bone metabolism by assessing lumbar spine BMD (primary endpoint), femoral neck BMD, and levels of the bone formation marker serum N-terminal pro-peptide of type 1 collagen; (2) to determine the biochemical responses by blood tests in men who receive the combination of TPTD+cinacalcet compared to men who get TPTD+placebo treatment. This is done by quantifying acute and chronic changes in serum calcium and PTH levels right after these drugs are given and how much calcium is excreted in the urine over time, with both treatment regimens. This study will help to understand whether an effective combination therapy in mice will prove to be effective in men.

  • Safety and Tolerability of Intravenous LLP2A-Alendronate for Osteopenia Secondary to Glucocorticoids

    Sorry, in progress, not accepting new patients

    A Phase 1 Randomized, Double-Blind, Placebo-Controlled Single and Multiple Ascending Dose Study of the Safety and Tolerability of Intravenous LLP2A-Alendronate in Adult Men and Women with Osteopenia Secondary to Corticosteroids.

  • Ultrarunners Longitudinal TRAcking Study (ULTRA)

    Sorry, accepting new patients by invitation only

    Health status information and physical activity level will be collected longitudinally on a large group of individuals who are ultramarathon runners at the time of enrollment to determine if very high levels of physical activity alter health risks compared with sedentary or moderately active lifestyles.
