Testing Osimertinib as a Treatment for Lung Cancers With an EGFR Exon 20 Change
Recruiting
This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Combination Therapy for the Treatment of Diffuse Midline Gliomas
Recruiting
This phase II trial determines if the combination of ONC201 with different drugs, panobinostat or paxalisib, is effective for treating participants with diffuse midline gliomas (DMGs). Despite years of research, little to no progress has been made to improve outcomes for participants with DMGs, and there are few treatment options. ONC201, panobinostat, and paxalisib are all enzyme inhibitors that may stop the growth of tumor cells by clocking some of the enzymes needed for cell growth. This phas... Read More

Controlled Human Infection Study of Orally Administered Trichuris Trichiura Eggs in Naïve Adults
Recruiting
A Controlled Human Infection Model (CHIM) is being developed to provide early proof-of-concept that experimental infection with the intestinal nematode, Trichuris trichiura, is feasible and safe. The proposed model consists of enrolling consenting, healthy, trichuriasis-naïve adults and challenging them with the investigational product, Trichuris trichiura Egg Inoculum, to assess their ability to result in detectable infection. The proposed study will be a feasibility study that will consist of... Read More
