Testing ZL-6201 for safety and early activity in sarcoma and other solid tumors
This trial will see if the antibody-drug conjugate ZL-6201 is safe and shows early anti-cancer activity in adults with sarcoma or certain other advanced solid tumors.
-
Single- and multiple-dose testing of ZL-1503 in adults with moderate to severe atopic dermatitis and healthy volunteers
This study will test whether single and repeated doses of the investigational drug ZL-1503 are safe and how the body processes them in healthy adults and adults with moderate to severe atopic dermatitis.
-
ZL-1310 versus doctor-selected therapy for relapsed small-cell lung cancer (DLLEVATE)
This will test whether ZL-1310 works better than a doctor-selected therapy for adults whose small-cell lung cancer has returned after prior platinum-based treatment.
-
ZL-1310 for selected advanced solid tumors
This will try the drug ZL-1310 in adults with selected advanced or metastatic solid tumors, especially neuroendocrine carcinomas that have progressed after platinum-based chemotherapy.
-
Evaluating ZL-1310 for Small Cell Lung Cancer
This study is testing a new drug called ZL-1310, alone and with other treatments, to see if it can help people with advanced small cell lung cancer who haven't responded to previous chemotherapy.
