Alendronate is a drug used to treat osteoporosis and primarily prevents bone loss, whereas PTH increases bone formation. We will treat the study participants either with PTH and alendronate, alendronate alone, or PTH alone. We will determine the effects of these treatments by looking for changes in bone mineral density in the hip and spine.', 'detailedDescription': 'The PaTH study is a 2-year, multicenter, double-blind, placebo-controlled trial to test the efficacy of combining hPTH (1-84) and alendronate for treating osteoporosis in postmenopausal women.\n\n238 women were randomized between 55 and 85 years of age to receive either: (1) PTH for 1 year followed by alendronate for 1 year; (2) PTH and alendronate for 1 year followed by alendronate for 1 year; (3) alendronate for 2 years; or (4) PTH for 1 year followed by placebo for 1 year. The primary endpoints are changes in bone mineral density at several sites and changes in biochemical markers.\n\nIn addition, we will assess specific biochemical markers of bone turnover (e.g., osteocalcin, deoxypridinoline, N-telopeptide, bone-specific alkaline phosphatase and bone sialoprotein) to determine if they can predict the skeletal response to combination therapy. We will also determine whether PTH positively affects ultrasound measurements in the calcaneus.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '55 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Aged between 55 and 85 years\n* Postmenopausal (have not had any menses in the last 5 years)\n* Have a bone mineral density scan (DXA) that can be evaluated at the spine AND at the hip with a T-score equal to or below -2.5 at the spine or the femoral neck or total hip OR T-score equal to or below -2.0 at the spine or the femoral neck or total hip and have at least one of the following risk factors for fracture: (a) age \\> 65 years;
