Active clinical trials for "Osteoporosis"

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.

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 60 years and older with Parkinson's disease and parkinsonism with at least 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.

The research will be conducted as a prospective, post-market, multi-center study within Europe. The maximum number of subjects to be treated is 150 across up to 20 sites. This will be a non-randomized and open-label study. The study will collect procedural, short- and long-term data on the safety and clinical performance of AGN1 LOEP in the post-market setting in European countries where AGN1 LOEP is commercially available. AGN1 is intended to form new bone in voids in the proximal femur of women with osteoporosis.

The purpose of this study is to find out if one year of romosozumab (Evenity®), a monthly injection given in the arm under the skin, prior to an infusion of zoledronic acid Reclast®, works to treat bone loss and prevent it from worsening in older women (ages 65 and older) who have osteoporosis and reside in long-term care (LTC) facilities.

This study is design to assess the effects of an increase in nutritional intake on the bone mineral density of children with sickle cell disease, for 12 months.

This study is to evaluate the efficacy and safety of JMT103 in the treatment of postmenopausal women with osteoporosis.

OPTIMIST is a two-year, randomised, active controlled, open-label, multicentre intervention trial. OPTIMIST includes 3 treatment groups each comprising combinations of romosozumab (ROMO) and zoledronate (ZOL) treatment used in standard doses (210 mg monthly (sc) and 5 mg yearly (iv), respectively). The study will investigate if it is possible to maximize the effect of romosozumab by giving it in 2 periods of 6 months interrupted by zoledronate for 12 months compared to romosozumab for 12 months uninterrupted followed by zoledronate for 12 months. The investigators will also evaluate if 6 months of romosozumab followed by 18 months of zoledronate is non-inferior to the standard regimen of romosozumab for 12 months followed by zoledronate for 12 months.

This is a phase 3 Randomized, Double-blind, Parallel-group, Active-controlled Study to Compare the Efficacy, Safety, Pharmacodynamics, Pharmacokinetics, and Immunogenicity of Enzene Denosumab (ENZ215) and Prolia® in Postmenopausal Women with Osteoporosis

Randomized pilot clinical trial to demonstrate superiority of bisphosphonate-magnesium combination over bisphosphonates alone in postmenopausal osteoporosis in slowing bone remodeling as assessed by C-terminal telopeptide of bone collagen type 1 (CTX) dosage.

Denosumab(Dmab) is a monoclonal antibody that inhibits the receptor-activator of nuclear factor kappa-B ligand. It improves bone density and reduces fractures by inhibiting osteoclast recruitment and differentiation. Although the FREEDOM trial showed Dmab increase bone mineral density for ten years, the effect was reversible. When Dmab is discontinued, the rebound phenomenon, the bone mineral density returns to the pre-treatment value, and multiple vertebral fractures may occur. Recently, a guideline to administer bisphosphonates sequentially when Dmab is discontinued has been published. In several studies, Zoledronic acid prevented bone loss after denosumab discontinuation with a single administration in Dmab short-term(less than 2.5years) users, but in Dmab long-term(more than 2.5years) users, zoledronic acid did not fully prevent loss of BMD. Our study tried to evaluate that ZOL administration twice for six months apart in long-term Dmab users is not inferior to a single administration of ZOL in Dmab short-term users.
