Preventing Nephrotoxicity and Ototoxicity From Osteosarcoma Therapy
Overview[ - collapse ][ - ]
Purpose | Osteosarcoma is the most common type of bone cancer in children, adolescents and young adults. Treatment with surgery and a combination of three conventional chemotherapy drugs can cure nearly two-thirds patients with osteosarcoma, but the treatment can also cause irreversible damage to the kidneys and cause permanent hearing loss. The purpose of this study is to evaluate new approaches to prevent these side effects without interfering with the beneficial effects of the chemotherapy drugs on the cancer by using our knowledge of how the drugs damage the kidney and cochlear hair cells in the ear to selectively block these side effects. Preventing these side effects without interfering with the anti-cancer effect of the drugs will improve the outcome in survivors and may also improve the effectiveness of the chemotherapy regimen by preventing treatment delays and dose reductions that are often caused by the side effects. Patients will be carefully monitored to ensure that the new interventions do not adversely affect response to the treatment and do not increase the other side effects of the chemotherapy. Specifically, we will monitor the nutritional status of the patients closely and ask patients to complete a survey describing the side effects after each treatment cycle. We will also collect a small sample of cancer tissue at the time of biopsy and surgery from each patient on this study for testing to determine new classes of anti-cancer drugs currently under development may have a role in treating osteosarcoma. If effective, these new approaches to prevent kidney damage and hearing loss will be applicable in other types of cancers treated with the same chemotherapy drugs. |

Detailed Description | Current osteosarcoma treatment regimens include cisplatin and high-dose methotrexate (HDMTX), which are nephrotoxic and ototoxic, and the damage to kidneys and cochlear hair cells may be irreversible. Preventing these toxicities will improve the outcome in long-term survivors and may also prevent short-term treatment delays and dose reductions that can compromise the efficacy of the treatment regimen and allow for administration of higher cumulative doses of cisplatin. This pilot study evaluates pharmacologically-based approaches to prevent the nephrotoxic effect of HDMTX by prolonging the infusion duration and thereby lowering the risk of drug precipitation in renal tubules; and to selectively block the uptake of cisplatin into renal tubular cells and cochlear hair cells by inhibiting the organic cation transporter 2 (OCT2) with the proton pump inhibitor (PPI), pantoprazole. Participants with previously untreated biopsy-proven, localized or metastatic osteosarcoma will receive six cycles of the standard MAP chemotherapy regimen, which includes high-dose methotrexate, doxorubicin and cisplatin. The first 2 cycles are administered neoadjuvantly followed by surgery to remove the primary tumor, when feasible. A novel randomized, crossover, 2 x 2 factorial clinical trial design allows all patients to receive the new interventions to prevent toxicity and to serve as their own controls. New, sensitive urinary biomarkers of acute kidney injury serve as primary endpoints for evaluating treatment-related renal damage. Ototoxicity will be monitored using audiograms. The effect of these interventions on tumor response (radiographic and histologic) and toxicity (including a patient reported outcome survey and nutritional status) will be closely monitored. Other secondary objectives include evaluating bone-specific alkaline phosphatase as a biomarker of tumor burden and constructing a tissue microarray to evaluate expression of proteins that are responsible for resistance to the current drugs used to treat osteosarcoma and assess expression of proteins that are targeted by new anticancer drugs under development for childhood cancers. |
