  Purpose
The objective of this study is to compare the rate and extent of absorption of alendronate sodium 70 mg tablets (test) versus Fosamax® 70 mg tablets (reference) administered as a single dose of 70 mg under fasting conditions. A review of pharmacokinetic data demonstrates Alendronate Sodium Tablets, 70 mg, manufactured and distributed by TEVA Pharmaceuticals USA are bioequivalent to Fosamax® Tablets, 70 mg, manufactured by Merck Sharp & Dohme, USA.

Condition Intervention Phase
Healthy Drug: Alendronate Sodium Tablets 70mg Drug: Fosamax® Tablets 70mg Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Official Title: Randomized, 2-Way Crossover, Bioequivalence Study of Teva Pharmaceuticals USA and Merck Sharp & Dohme (USA) (Fosamax®) Alendronate Sodium Tablets Administered as a 1 x 70 mg in Healthy Adult Males Under Fasting Conditions

Criteria

Inclusion Criteria:

  • Subjects will be males, non-smokers, between 18 and 45 years of age.
  • Subjects' weight will be within 15% of their ideal body weight based on the Table of "Desirable Weight of Adults", Metropolitan Life Insurance Company, 1983
  • Subjects should read, sign, and date an Informed Consent Form prior to any study procedures.
  • Subjects must complete all screening procedures within 28 days prior to the administration of study medication.

Exclusion Criteria:

  • Clinically significant abnormalities found during medical screening.
  • Any history or presence of significant neurological, hepatic, renal, endocrine, cardiovascular, pulmonary, hematologic, immunologic, psychiatric or metabolic disease.
  • Any clinically significant history of ongoing gastrointestinal problems or problems known to interfere with the absorption, distribution, metabolism or excretion of drugs (e.g. chronic diarrhea, inflammatory bowel diseases).
  • Clinically significant illnesses within 4 weeks of the administration of study medication.
  • Abnormal laboratory tests judged clinically significant.
  • ECG or vital signs abnormalities (clinically significant).
  • History of allergic reactions to alendronate or other related drugs (e.g. clodronate, etidronate and pamidronate).
  • History of allergic reactions to heparin.
  • Any food allergies, intolerances, restrictions, or special diet which in the opinion of the medical subinvestigator, contraindicates the subject's participation in this study.
  • Positive urine drug screen at screening or at check-in of period I.
  • Positive testing for hepatitis B, hepatitis C or HIV at screening.
  • Use of an investigational drug or participation in an investigational study, within 30 days prior to administration of the study medication.
  • Recent donation of plasma (500 mL) within 7 days or recent donation or significant loss of whole blood (450 mL) within 56 days prior to administration of the study medication.
  • History of significant alcohol abuse within six months of the screening visit or any indication of the regular use of more than two units of alcohol per day (1 Unit = 150mL of wine or 360 mL of beer or 45 mL of alcohol 40%).
  • Recent history of drug abuse or use of illegal drugs: use of soft drugs (such as marijuana, pot) within 3 months of the screening visit or hard drugs (such as cocaine, phencyclidine (PCP), crack) within 1 year of the screening visit.
  • Subjects who have used tobacco within 90 days of the start of the study.
  • Subjects who have taken prescription medication 14 days preceding administration of study medication or over-the-counter products 7 days preceding administration of study medication, except for topical products without systemic absorption.
  • Subjects who have taken any drugs known to induce or inhibit hepatic drug metabolism within 30 days prior to administration of the study medication (examples of inducers: barbiturates, carbamazepine, phenytoin, glucocorticoids, rifampin/rifabutin; examples of inhibitors: antidepressants, cimetidine, diltiazem, erythromycin, ketoconazole, MAO inhibitors, neuroleptics, verapamil, quinidine).
  • Subjects who have undergone clinically significant surgery 4 weeks prior to the administration of the study medication.
  • Any reason which, in the opinion of the medical subinvestigator, would prevent the subject from participating in the study.
