Collaborative Care for Polysubstance Use in Primary Care Settings (Co-Care)
Recruiting
The purpose of this trial is to test the efficacy of a collaborative care intervention to address opioid- and/or stimulant-involved polysubstance use in adult primary care patients with moderate to severe substance use disorders (SUD). The primary aims are to reduce days of opioid use (illicit or nonmedical opioid use), days of illicit stimulant use (cocaine, methamphetamine), and days of heavy alcohol use.

Chemotherapy Combined With Immunotherapy Versus Immunotherapy Alone for Older Adults With Stage IIIB-IV Lung Cancer, The ACHIEVE Trial
Recruiting
This phase III trial compares the effect of adding chemotherapy to immunotherapy (pembrolizumab) versus immunotherapy alone in treating patients with stage IIIB-IV lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividin... Read More

Recruiting
This is a study evaluating the safety and efficacy of bomedemstat (MK-3543) compared with the best available therapy (BAT) in participants with essential thrombocythemia (ET) who have an inadequate response to or are intolerant of hydroxyurea.
