Condition(s) targeted: Lung Cancer

Intervention: Ibandronate (Bondronat) (Drug)

Phase: Phase 4

Status: Terminated

Sponsored by: Chinese Society of Lung Cancer

The objective of this trial is to assess the efficacy and safety of loading doses versus standard dose of intravenous Bondronat in reducing pain in patients with lung cancer and bone metastatic disease.

Clinical Details

Official title: A Randomized Study to Evaluate the Safety and Efficacy of Loading Dose of Bondronat Versus Standard Dose of Bondronat in Patients With Lung Cancer and Skeletal Metastasis Experiencing Moderate to Severe Pain

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: bone pain response (≥25% decrease in mean pain score with a maximum of 15% increase in mean analgesic consumption)

Secondary outcome: Efficacy: ECOG Performance status, Analgesic consumption, bone marker Safety: AE, laboratory parameters

Detailed description: Patients with lung cancer and bone metastatic disease may experience moderate or severe bone pain. Some researches have reported that loading doses Bondronat (6mg Bondronat on three consecutive days) had great efficacy in reducing pain in patients with malignant bone disease without unacceptable toxicities. So,we designed this clinical trial to compare the efficacy and safety profiles between loading doses Bondronat and standard dose Bondronat. Enrolled patients will receive an intravenous infusion of either 6mg Bondronat on three consecutive days or 6mg Bondronat on one day. The targeted sample size is 120 individuals. Primary outcome measures will be bone pain response ( ≥ 25% decrease in mean pain score with a maximum of 15% increase in mean analgesic consumption). Secondary outcome measures will be efficacy including ECOG Performance status, analgesic consumption, bone markers, and safety profiles including AE and laboratory parameters.
