NCT ID: NCT03396315 Completed - Osteoporosis Clinical Trials

Bisphosphonates for Prevention of Post-Denosumab Bone Loss

Start date: January 29, 2018
Phase: Phase 2
Study type: Interventional

The primary goal of the study is to assess the extent to which bisphosphonate therapy will prevent decreases in bone mass that may occur after cessation of denosumab in premenopausal women with idiopathic osteoporosis (IOP) enrolled in AAAN0161 (FD05114) "Denosumab for the prevention of post-teriparatide bone loss in premenopausal women with idiopathic osteoporosis". In addition, the investigator will observe participants for a second year off bisphosphonate therapy to assess duration of response. The hypothesis is that bisphosphonate therapy with alendronate or zoledronic acid, initiated after recovery of bone remodeling activity, will prevent significant bone loss after discontinuing denosumab.

NCT ID: NCT03107429 Completed - IOP Clinical Trials

Effect of Acetazolamide on Intraocular Pressure After Being in the Trendelenburg Position.

TaPPs
Start date: March 1, 2015
Phase: N/A
Study type: Interventional

Perioperative vision loss following laparoscopic colorectal surgery is rare but has been reported. Studies show Trendelenburg positioning during surgery can produce a significant rise in the IOP, and this rise is thought to be a possible factor. Acetazolamide decreases IOP by reducing the formation of aqueous humour. Aims: To investigate if acetazolamide reduces the IOP rise resulting from Trendelenburg positioning. Methods: A randomised cross-over blinded pilot study. Nine healthy volunteers were randomised to start with the placebo or Acetazolamide with a 5 days' washout period. Baseline IOP was measured on both days. After 1.5 hours of taking the medication, volunteers lay head-down at 17 degrees' for 4 hours and IOP measurements repeated. This reading was subtracted from the baseline to give a 'change in IOP'.
