Study ID: NCT03173976

Conditions

Interventions

Zoledronic Acid

Study Description

Brief Summary: The purpose of this single arm open label phase 1b clinical study is to see what effect zoledronic acid has on tumors in patients with resectable any grade chondrosarcoma prior to surgery.

Detailed Description: This is a single arm open label phase 1b clinical trial assessing the safety and efficacy of neoadjuvant zoledronic acid in patients with resectable any grade chondrosarcoma as measured by pathological characteristics and recurrence free survival. Prior to surgery, subjects will receive 1 standard dose of IV zoledronic acid given over 15 minutes. Surgery will be performed 21-31 days after the dose as per standard of care. The second standard dose of zoledronic acid will be given 3 weeks after surgery. Phase 1b: The Phase 1b portion of this study is to ensure the safety and tolerability of standard dose of zoledronic acid intravenously as assessed by incidence of dose limiting toxicities (DLT). Although the safety of use of this drug has been established in patients with bone metastases from solid tumors (breast, prostate) and in patients with hypercalcemia of malignancy and multiple myeloma, it has not been tested in patients with chondrosarcoma. Surgery will be performed between day 21 to 31 from the dose of zoledronic acid to allow its effect on the tumor and resolution of toxicities. A total of 6 patients will be enrolled in this run-in phase 1b. Patients will be followed post operatively as per NCCN guidelines (for years 1 and 2) with local and systemic imaging. Expansion Cohort: The phase 1 b expansion cohort of the study will provide an estimate of the relative treatment effect of zoledronic acid on any grade chondrosarcoma specimens. Subjects will receive a total of 2 doses of zoledronic acid, one dose prior to surgery and the second dose 21 days after surgery. Patients will undergo standard of care surgery 21-31 days from the first dose of zoledronic acid. 9 subjects will be enrolled in this cohort for a total of 15 planned subject enrollment over 3 years. Patients will be followed post operatively for recurrence with imaging and survival and as per NCCN guidelines (for years 1 and 2).
