Brief summary

This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. Investigational means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA has not approved the drug for this type of cancer, or for any use outside of research studies. When cancer spreads from the primary tumor, one of the most commons sites it spreads to is bone. When cancer spreads to bone there can be significant symptoms such as pain. Cabozantinib works by blocking signaling that leads to cancer growth as well as blocking the growth of new blood vessels (angiogenesis) that help to feed a tumor. Cabozantinib has been studied or is being studied in research studies as a possible treatment for various types of cancer, including prostate cancer, brain cancer, thyroid cancer, lung cancer and kidney cancer. Previous clinical research studies indicate that cabozantinib may also have activity against cancer once it has spread to the bones. The purpose of this study is to find out if cabozantinib is effective in treating cancer that has spread to the bone.

Detailed description

Cabozantinib is a tablet that the subject will take by mouth. The subject will take it once per day. The study treatment with cabozantinib will be divided into 28 day cycles. A member of the study staff will give the subject a drug diary and explain to the subject how to use it to record doses of cabozantinib. This diary will also contain specific instructions about how the subject take cabozantinib. Every 28 days the subject will undergo the following procedures: Physical examination, questions about any side effects the subject may have, blood samples for routine laboratory tests and research tests, urine sample, electrocardiogram (EKG), and questionnaires to measure quality of life and level of pain. Every two months the subject will undergo a CT scan or MRI to evaluate the subjects disease. The investigators would like the subject to return to the study clinic for follow-up procedures about 4-5 weeks after the last dose of cabozantinib. The subject can continue to receive the study drug for as long as their disease does not worsen and the subject do not experience unacceptable side effects.

Effect of cabozantinib on bone biomarkers of osteoblast and osteoclast activity. The bio-markers of interest were serum C-terminal telopeptide (Ctx), urine N-terminal telopeptide (Ntx), serum (Ntx). Participants were considered to have a response if there was at least a 40% decrease in the bio-marker concentration.
