Clinical trials

The study is designed to understand the safety, tolerability, pharmacokinetics, immunogenicity, and preliminary antitumor activity of MGC026 in participants with relapsed or refractory, unresectable, locally advanced or metastatic solid tumors The study has a dose escalation portion and a cohort expansion portion of the study. Participants will receive MGC026 by intravenous (IV) infusion. The dose of MGC026 will be assigned at the time of enrollment. Participants may receive up to 35 treatments if there are no severe side effects and as long as the cancer does not get worse. Participants will be monitored for side effects, and progression of cancer, have blood samples collected for routing laboratory work, and blood samples collected for research purposes.

Study CP-MGD019-03 is an open-label study of lorigerlimab in participants with platinum-resistant ovarian cancer (PROC) or clear cell gynecologic cancer (CCGC). Approximately 80 participants will be enrolled. The study will assess the efficacy and safety of lorigerlimab in participants with PROC or CCGC. Participants will receive lorigerlimab by intravenous (IV) infusion on Day 1 of every 21-day treatment cycle. Treatment cycles will continue until progression of cancer, unacceptable side effects, withdrawal of consent by the participant, or the study ends. Participants will be monitored closely for side effects by physical exam and routine laboratory tests every cycle. Tumor status will be checked approximately every 9 weeks for the first year, then every 12 weeks for the duration of treatment. Participants will have a safety followup performed within 30 days after treatment discontinuation. Participants who discontinue study treatment for reasons other than progression of cancer, will continue CA-125 and tumor assessments every 12 weeks. Participants who discontinue study treatment for progression of cancer will enter the 6-month survival follow up portion of the study.

The goal of this clinical trial is to characterize the safety, tolerability, dose-limiting toxicities (DLT), and maximum tolerated dose (MTD) or maximum administered dose of MGC028 (if no MTD is defined). The study will enroll adult participants with relapsed or refractory, unresectable, locally advanced of metastatic solid tumors known to express ADAM9. The main question the study aims to answer is: * What types of side effects will participants experience when receiving MGC028? * Can MGC028 cause cancer to shrink, remain stable, or able to control disease progression of participants with advanced solid tumors? Participants will * Undergo screening procedures to determine eligibility * Receive study treatments initially every 3 weeks. * Have blood samples taken for routine and research tests * Have other examinations to check heart and lung function, and general health status * Be asked about any side effects that may be happening or other medications you are taking. The study doctor will provide treatment for side effects, if necessary. * Have the study doctor assess your tumor status at regular intervals to determine how you are responding to treatment.
