Brief Summary
Osteoporosis is a disease that affects millions of individuals in the United States and abroad. It leads to decreased bone mass and causes an increased risk of fracture. This study will compare continuous versus cyclic treatment with teriparatide combined with alendronate, another drug for osteoporosis, or teriparatide alone in women with osteoporosis.

1
EXPERIMENTALParticipants in this group will have been treated with alendronate for at least 1 year prior to study entry. Upon study entry, they will receive a continuous regimen of daily teriparatide (20 mcg subcutaneously) for 48 months, in addition to alendronate. Biopsies will be performed at Week 7 or Month 7.5. The participants will then have the option to be followed while taking alendronate alone for 24-48 months.
2
EXPERIMENTALParticipants in this group will have been treated with alendronate for at least 1 year prior to study entry. Upon study entry, they will receive a cyclical regimen of teriparatide, in addition to alendronate. Teriparatide will be administered subcutaneously in 20-mcg doses daily for 3 months. They will receive no teriparatide for the following 3 months, and then teriparatide treatment will continue for the 3 months after that. This schedule will continue for 24 months with an aption to all participants to continue cyclic teriparatide for another 24 months. Biopsies will be performed at Week 7 or Month 7.5.
3
ACTIVE COMPARATORParticipants in this group will have been treated with alendronate for at least 1 year prior to study entry. Upon study entry, they will continue taking alendronate alone. Biopsies will be performed at Week 7 and then participants in this group will be offered teriparatide as part of Group 2 or 3.
4
EXPERIMENTALParticipants in this group will receive a continuous regimen of teriparatide (20 mcg delivered subcutaneously) daily for 48 months. Biopsies will be performed at Week 7 or Month 7.5. At 24 months the participants will then have the option of taking alendronate and remaining in the study for another 24 months.
5
EXPERIMENTALParticipants in this group will receive a cyclical regimen of teriparatide. Teriparatide will be administered subcutaneously in 20-mcg doses daily for 3 months. They will receive no teriparatide for the following 3 months, and then teriparatide treatment will continue for the 3 months after that. This schedule will continue for 24 months with an option to all participants to continue cyclic teriparatide for another 24 months. Biopsies will be performed at Week 7 or Month 7.5.
6
ACTIVE COMPARATORParticipants in this group will take only calcium and vitamin D supplements. Biopsies will be performed at Week 7. Participants will then be offered the standard care for osteoporosis or they may enter the study in Group 4 or 5.
Interventions
Teriparatide will be given subcutaneously in 20-mcg doses either continuously or cyclically.
Calcium supplements will be administered in varied amounts for all participants, but each participant will take enough to bring her total daily calcium intake to 1,200 mg.
Vitamin D3 supplements will be administered in varied amounts for all participants, but each participant will take enough to bring her total daily intake to 1,200 mg.
Eligibility Criteria
You may qualify if:
- Diagnosis of osteoporosis or T score below -2 plus one or more osteoporosis related fractures
- Two measurable vertebrae between L1 and L4
- Willing to undergo a single iliac crest biopsy after administration of 4 tetracycline labels
You may not qualify if:
- Secondary causes of osteoporosis or presence of a skeletal disorder other than osteoporosis
- Uses drugs likely to affect skeletal or calcium homeostasis

- Use of hormone therapy, estrogen therapy, raloxifene, or calcitonin within 6 months before study entry
- Use of any bisphosphonate for more than 3 months within 2 years before study entry (only applies to participants in Groups 4, 5, and 6)
- History of a kidney stone within 5 years before study entry or any history of multiple kidney stones
- Hypercalcemia, hypercalciuria, or elevated parathyroid hormone (reduced 25-hydroxyvitamin D will be corrected prior to admission)

- History of external radiation therapy
- Unlikely or unable to complete the study, as determined by the investigators
- Illicit drug use or excessive alcohol consumption
