A phase II trial of the pan-class I PI3K inhibitor copanlisib demonstrated that it induces objective responses in 59% of patients with relapsed or refractory indolent lymphoma. The responses lasted a median of 22.6 months. Although the drugs weren't compared head to head, researchers suspect that the side effects of copanlisib may be less severe than those of idelalisib, another PI3K inhibitor.

The investigational ALK inhibitor lorlatinib, whose early clinical activity was first reported last year, continues to look promising in advanced ALK-positive or ROS1-positive non-small cell lung cancer. In a phase II study, robust responses were seen in previously untreated patients, as well as those who had received as many as three prior ALK inhibitors.
