What's being studied?

<ul class="seamTextUnorderedList"> <li class="seamTextUnorderedListItem">TOS-358 is an experimental targeted therapy called a PI3K inhibitor.</li> <li class="seamTextUnorderedListItem">If there is a mutation in the PIK3CA gene, the PI3K pathway can become overactivated, allowing cancer cells to grow. TOS-358 may slow or stop cancer cells from growing by blocking this pathway.</li> <li class="seamTextUnorderedListItem">This trial is also enrolling people with other types of cancer.</li> <li class="seamTextUnorderedListItem">Targets or mutations: PIK3CA</li></ul>
