Study Endpoints

Primary Endpoints

Number of Participants With Adverse Events (AEs), Immune Mediated AEs (imAEs) and Serious AEs (SAEs)
From Cycle 1 Day 1 (each cycle was 28 days in length) until Day 90 (post last dose of study intervention), up to 34 months

The safety and tolerability of study intervention (AZD0171, durvalumab, and standard-of-care chemotherapy) was assessed. The grading scales found in the revised National Cancer Institute CTCAE latest version was utilized for all events with an assigned CTCAE grading. Grade refers to the severity of the AE. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL. Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living (ADL); Grade 4: Life-threatening, urgent intervention required; Grade 5: Death related to AE.

Overall Survival at 12 Months (OS-12)
At 12 months

Percentage of participants alive at 12 months after initiation of study intervention per Kaplan- Meier estimate of OS at 12 months.

Evaluate the safety and tolerability of MSC-1 and determine the recommended dose for MSC-1 monotherapy for further evaluation in the expansion part of the study
Patients will be evaluated for approximately 6 months or until disease progression

Assessment of frequency \& severity of adverse events

Assess the preliminary anti-tumor activity of MSC-1 monotherapy
Patients will be evaluated for approximately 6 months or until disease progression

Determine objective response rate (ORR)

Secondary Endpoints

Objective Response Rate (ORR)
From Cycle 1 Day 1 (each cycle was 28 days in length) until initiation of subsequent anti-cancer treatment and prior to progression (up to 35 months).
Disease Control Rate (DCR)
Up to 16 weeks
Duration of Response (DoR)
From screening until disease progression or last evaluable assessment in the absence of progression, whichever came first (up to 35 months)

Frequently asked questions about MSC-1

What is MSC-1 used for?

MSC-1 is an investigational monoclonal antibody being developed for the treatment of advanced solid tumors, including pancreatic cancer, non-small cell lung cancer, and ovarian cancer. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does MSC-1 target?

MSC-1 is a monoclonal antibody, but its specific molecular target has not been disclosed in available information. The drug is being studied for its safety, pharmacokinetics, pharmacodynamics, immunogenicity, and antitumor activity in patients with advanced solid tumors.

Who makes MSC-1?

MSC-1 is being developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker symbol AZN. The company is conducting clinical trials to evaluate the drug's potential in treating advanced solid tumors.

What phase is MSC-1 in?

MSC-1 is in Phase 1 clinical development. A Phase 1 study has been completed, and the drug remains investigational. It has not received FDA approval and is still undergoing clinical evaluation for safety and efficacy in patients with advanced solid tumors.

What clinical trials is MSC-1 in?

MSC-1 has been studied in one clinical trial, identified as NCT03490669, which was a Phase 1 study evaluating the safety, pharmacokinetics, pharmacodynamics, immunogenicity, and antitumor activity of MSC-1 in patients with advanced solid tumors. The trial was completed and enrolled 41 participants.
