This is a Phase 3, open-label, international, multicenter study of CGT9486 in combination
with sunitinib. This is a multi-part study that will enroll approximately 426 patients. Part
1 consists of two evaluations: 1) confirming the dose of an updated formulation of CGT9486 to
be used in subsequent parts in approximately 20 patients who have received at least one prior
line of therapy for GIST and 2) evaluating for drug-drug interactions between CGT9486 and
sunitinib in approximately 18 patients who have received at least two prior tyrosine kinase
inhibitors (TKIs) for GISTs. The second part of the study will enroll approximately 388
patients who are intolerant to, or who failed prior treatment with imatinib only and will
compare the efficacy of CGT9486 plus sunitinib to sunitinib alone with patients being
randomized in a 1:1 manner.

This phase III trial compares the effect of radiation therapy combined with hormonal therapy versus hormonal therapy alone in treating patients with low risk, early stage breast cancer with Oncotype Dx Recurrence =< 18. Oncotype DX is a laboratory test which results in a score that is used to help predict whether breast cancer will spread to other parts of the body or come back. Radiation therapy uses high doses of radiation to kill cancer cells and shrink tumors but may result in some side effects. Hormones called estrogen and progesterone may contribute to the growth of breast tumor cells. Hormone therapy, also called endocrine therapy, may stop the growth of tumor cells by blocking or removing these hormones. This clinical trial may help researchers understand if patients with low-risk, early stage breast cancer who have Oncotype recurrence score of =< 18 can safely omit radiation therapy and only be treated with hormonal therapy without losing any radiation treatment benefit.
