Sponsored by AstraZeneca · Phase 1, Interventional, and Treatment
This is a 2-part study to evaluate the safety and antitumor activity of MSC-1. MSC-1 is a first-in-class, humanized monoclonal antibody (IgG1) which binds to the immunosuppressive human cytokine Leukemia Inhibitory Factor (LIF), and is intended to treat adult patients with Advanced Solid Tumors.
In part 1, multiple dose levels of MSC-1 in patients with advanced solid tumors will be studied to determine the recommended dose for further evaluation of safety and efficacy in Part 2.
MSC-1 is a first-in-class, humanized monoclonal antibody (IgG1) which binds to the immunosuppressive human cytokine Leukemia Inhibitory Factor (LIF), and is intended to treat adult patients with advanced solid tumors. LIF is a pleiotropic cytokine involved in many physiological and pathological processes including the promotion of an immunosuppressive environment. In cancer, it is hypothesized that LIF expressing malignancies co-opt this activity, creating an immunosuppressive tumor microenvironment as well as promoting the activity of cancer-initiating cell(s) (CICs). LIF is highly expressed in a subset of tumors across multiple solid tumor types.
During dose escalation, patients with advanced solid tumors will be treated with MSC-1 with the primary objective of determining the safety and tolerability of MSC-1 and defining an appropriate dose for further evaluation in dose expansion. MSC-1 will be administered intravenously (IV) until disease progression, unmanageable toxicity, withdrawal of consent or study termination.
In dose expansion, up to 4 parallel cohorts of patients with LIF-High tumors (NSCLC, Ovarian Cancer, Pancreatic Cancer), and a cohort of mixed solid tumors (referred to as the "basket cohort"), may be treated at the recommended expansion dose to further characterize the safety, tolerability, PK, PD and anti-tumor activity of MSC-1.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
