Blood samples will be collected to determine the AUC0-Inf of alendronate.

Maximum Plasma Concentration (Cmax) of Alendronate
At designated timepoints (up to approximately 10 hours post-dose)

Blood samples will be collected to determine the Cmax of alendronate.

Time to Maximum Plasma Concentration (Tmax) of Alendronate
At designated timepoints (up to approximately 10 hours post-dose)

Blood samples will be collected to determine the Tmax of alendronate.

Apparent Terminal Half-Life (t1/2) of Alendronate
At designated timepoints (up to approximately 10 hours post-dose)

Blood samples will be collected to determine the t1/2 of alendronate.

Apparent Clearance (CL/F) of Alendronate
At designated timepoints (up to approximately 10 hours post-dose)

Blood samples will be collected to determine the CL/F of alendronate.

Treatment Arms

ArmTypeDescription
1 Alendronate, Calcium, Vitamin DEXPERIMENTALCrossover study. Year-1, 10 participants will take study medication, calcium and vitamin D supplements and other 10 participants will take placebo, calcium and vitamin D supplements. Year-2, they will crossover to the second arm of the study. Those who took study medication and supplements in year-1, will take placebo and supplements in the year-2, and those 10 participants who took placebo and supplements in the year-1, will take study medications and supplements in the year-2.
2 Placebo, Calcium and Vitamin DPLACEBO_COMPARATORYear-1, 10 participants will take Alendronate (study medication)and calcium and vitamin D supplement). Another 10 participants will take placebo, calcium and vitamin D. In year-2 they will crossover. Those who took alendronate in the first year, will take Placebo, calcium and vitamin D for 12 months and those who took Placebo in the first year, will take Alendronate, calcium and vitamin D in the second year (12 months).
AlendronateEXPERIMENTALParticipants receive a single oral dose of alendronate on Day 1 OR participants receive a single oral dose of alendronate on Day 15 depending on randomization.
Alendronate + Enlicitide DecanoateEXPERIMENTALParticipants receive an oral dose of alendronate plus an oral dose of enlicitide decanoate on Day 1 OR participants receive an oral dose of alendronate plus an oral dose of enlicitide decanoate on Day 15 depending on randomization.

Frequently asked questions about Alendronate

What is Alendronate used for?

Alendronate is used for osteoporosis and is being studied in healthy adults. It is a small molecule developed by Merck & Company, Inc. (MRK). In clinical trials, it has been evaluated in children with osteoporosis and in healthy adult participants for drug-drug interaction studies.

Who makes Alendronate?

Alendronate is developed by Merck & Company, Inc., which trades under the ticker MRK. The company has conducted clinical trials evaluating the drug in osteoporosis and healthy populations.

What phase is Alendronate in?

Alendronate is in Phase 1 clinical development. It has completed trials, including a Phase 2 study in children with osteoporosis and a Phase 1 study in healthy adults. It remains investigational and is not approved for the studied indications.

What clinical trials is Alendronate in?

Alendronate has been studied in two completed trials: NCT00259857, a Phase 2 safety and efficacy study in children with osteoporosis, and NCT06772792, a Phase 1 drug-drug interaction study with enlicitide decanoate in healthy adults. Both trials were conducted in the United States.

Is Alendronate the same as Fosamax?

Yes, Alendronate is the same as Fosamax. The clinical trial NCT00259857 is titled 'Safety and Efficacy of Alendronate (Fosamax) in Children With Osteoporosis,' confirming that Fosamax is an alternative name for Alendronate.
