Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00004488 ↗	Phase II Randomized Study of Alendronate Sodium for Osteopenia in Patients With Gaucher's Disease	Completed	Children's Hospital Medical Center, Cincinnati	Phase 2	1998-10-01	OBJECTIVES: I. Determine the efficacy of alendronate sodium in treating osteopenia (generalized bone density and focal bone lesions) in patients with Gaucher's disease.
NCT00000412 ↗	Osteoporosis Prevention After Heart Transplant	Completed	Merck Sharp & Dohme Corp.	Phase 3	1997-09-01	During the first year after a heart transplant, people often rapidly lose bone from their spine and hips. About 35 percent of people who receive heart transplants will suffer broken bones during the first year after transplantation. This study will compare the safety and effectiveness of the drug alendronate (Fosamax) and the active form of vitamin D (calcitriol) in preventing bone loss at the spine and hip after a heart transplant. In this study, people who have had a successful heart transplant will receive either active alendronate and a "dummy pill" instead of calcitriol, or active calcitriol and a dummy pill instead of alendronate for the first year after their transplant, starting within 1 month after transplant surgery. We will measure bone density in the hip and spine at the start of the study and after 6 and 12 months, and will also check for broken bones in the spine. This research should lead to ways of preventing this crippling form of osteoporosis.

Alendronate Sodium: Clinical Trials, Market Analysis, and Projections

Introduction

Alendronate sodium, a bisphosphonate, is widely used in the treatment of osteoporosis and other bone-related disorders. This article provides an update on the clinical trials, market analysis, and future projections for this drug.

Clinical Trials: Efficacy and Safety

Bone Density and Fracture Risk

A significant clinical trial published in JAMA highlighted the effects of alendronate on bone density and fracture risk. The study involved 4432 women randomized to either alendronate or a placebo. The results showed that alendronate increased bone mineral density (BMD) at all measured sites and reduced the risk of clinical fractures, although the reduction was not statistically significant for all types of fractures. Specifically, alendronate reduced the risk of hip fractures by 14% and clinical fractures by 12.3% compared to the placebo group[1].

Generic vs. Brand Alendronate

A randomized clinical trial comparing generic and brand alendronate found that both formulations produced similar gains in BMD and reductions in bone turnover markers. The study concluded that generic and brand alendronate were equally effective and well-tolerated, with no significant differences in BMD changes at the lumbar spine, total hip, or femoral neck after one year of treatment[3].

Long-Term Use and Discontinuation

Another study examined the effects of continuing or stopping alendronate after 5 years. Women who discontinued alendronate showed a moderate decline in BMD and an increase in biochemical markers of bone turnover, but the mean BMD levels remained above pretreatment levels. The study found no significant difference in the cumulative risk of nonvertebral fractures between those who continued and those who discontinued alendronate, although there was a lower risk of clinically recognized vertebral fractures among those who continued the treatment[4].

Market Analysis

Global Market Size and Growth

The global alendronate sodium market is experiencing significant growth. As of 2023, the market size was valued at several million USD and is anticipated to grow at a compound annual growth rate (CAGR) from 2024 to 2031. The market is segmented by type (above 98% and below 98% purity) and application (primarily osteoporosis and other bone-related conditions)[2][5].
