What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only

Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase I/II platform trial tests several drug combinations, including evorpacept, trastuzumab deruxtecan, zanidatamab, tucatinib, and TTX-MC138, in people with advanced solid tumors, especially metastatic breast cancer. The goal is to find safe and promising regimens that could move into larger trials. Participants receive one of the drug combinations, and researchers monitor side effects, tumor response, and how long any benefit lasts.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A combination of drugs including evorpacept, trastuzumab deruxtecan, zanidatamab, tucatinib, and TTX-MC138, given alone or together depending on the trial arm.
What this could lead to
If successful, this trial could identify drug combinations that shrink or control advanced solid tumors, potentially leading to larger studies and new treatment options for people with hard-to-treat cancers.
What could go wrong
This is an early-phase trial, so the drugs may not work as hoped or may cause severe side effects. The results will only show preliminary safety and effectiveness, not a proven cure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

General Inclusion Criteria (GIC): * GIC1: The participant must have ability to understand and willingness to provide signed written informed consent prior to any study related assessments and procedures and for collection of archival FFPE blocks for research. If FFPE blocks cannot be submitted, 20 to 40 freshly cut FFPE tissue slices (4 to 7 microns thick each) from a representative FFPE block, mounted on charged glass slides and left unstained will be acceptable. This criteria can be modified in specific drug regimens. * GIC2: Age ≥ 18 years at the time of signing the informed consent * GIC3: Gender: Male or female (premenopausal and postmenopausal) * GIC4: ECOG performance status Grade 0-2. This criteria can be modified in specific drug regimens. * GIC5: Estimated life expectancy \> 12 weeks at the start of investigational medicinal product (IMP) treatment. * GIC6: Adequate organ function, evidenced by the following laboratory results within 30 days of the start of IMP: * Absolute neutrophil count ≥ 1,500/mm3 * Platelet count ≥ 100,000/mm3 * Hemoglobin ≥ 9.0 g/dL with no blood transfusion in the past 28 days * Total bilirubin ≤ 1.5 x the upper limit of normal (ULN) * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3.0 x ULN * Estimated Creatinine clearance (using Cockcroft-Gault formula) ≥ 60 mL/min for small molecules and \>30 mL/min for monoclonal antibodies unless otherwise specified in the Arm Specific Eligibility. These cut-off values may be modified with supporting data for specific drug regimens. * GIC7: Non-Pregnant: Serum or urine pregnancy test must be negative within 14 days of IMP treatment start in women of childbearing potential. Pregnancy testing does not need to be pursued in patients who are judged as postmenopausal before enrollment, or who have undergone bilateral oophorectomy, total hysterectomy, or bilateral tubal ligation. If male, they must agree to refrain from donating sperm during treatment. * GIC8: Contraception: Women of childbearing potential and men must be willing to use adequate contraception for the duration of protocol treatment. Additional information regarding contraception for the specific treatment arm will be added to the drug arm description. Adequate contraception is defined as one highly effective form (i.e., abstinence, (fe)male sterilization) OR two effective forms (e.g., non-hormonal IUD and condom / occlusive cap with spermicidal foam / gel / film / cream / suppository). * GIC9: Prior therapy effects: Resolution of all acute toxic effects of prior therapy, including radiotherapy, to grade ≤1 and neuropathy to grade ≤2 (except toxicities not considered a safety risk for the patient) and recovery from surgical procedures. * GIC10: Participant compliance: Patients who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. * Additional arm specific inclusion criteria as needed by drug arm regimen General Exclusion Criteria (GEC): * GEC1: Wash out periods: Other anticancer therapy within the following period: * chemotherapy or investigational agents, 3 weeks * mitomycin C and nitrosoureas, 6 weeks * if radiotherapy is less than 5 days, 1 week wash out; if \>5 days, then 2 weeks washout * for radionuclides, contact Study PI or Study Chaperone to determine washout * targeted therapy, 2 weeks * MAbs, ADCs, and immunotherapy, 3 weeks * endocrine therapy, no washout needed * GEC2: Concurrent therapy with other Investigational Products. * GEC3: Prior history of drug/regimen hypersensitivity: History of infusion-related reactions and/or hypersensitivity to IMP or excipients of the study drug/drugs which led to permanent discontinuation of the treatment. * GEC4: Uncontrolled intercurrent illness including active infection, diabetes, adrenal insufficiency, pulmonary embolism, stroke in the past 6 months, or psychiatric illness/social situations that would limit compliance with study requirements. * GEC5: Cardiovascular disease: History (within 6 months prior to start IMP) of clinically significant cardiovascular disease such as unstable angina, congestive heart failure (CHF), myocardial infarction, uncontrolled hypertension, cardiac arrhythmia requiring medication, or baseline corrected QT by Fridericia's formula (QTcF) length \> 470 msec for men and women. The QTcF cut-off value may be modified with supporting data for specific drug regimens. * GEC6: CNS tumoral spread: Active uncontrolled/symptomatic central nervous system cancer/spinal cord compression. Previously treated and clinically stable lesions, as per Investigator's judgment, are permitted. Exception: Newly discovered asymptomatic lesions that are not life threatening and do not require urgent local treatment to ensure patient safety, including new parenchymal lesions or leptomeningeal disease, if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy, after consultation with study regimen chaperones, may be permitted. This criteria can be modified in specific drug regimens. * GEC7: Liver disease: Patients with clinically significant history of liver disease, including viral or other known hepatitis, current alcohol abuse, or cirrhosis. * GEC8: Recent major surgery within 4 weeks prior to start IMP treatment * GEC9: Pregnancy or breastfeeding * GEC10: Individuals accommodated in an institution because of regulatory or legal order; prisoners or participants who are legally institutionalized. * GEC11: Other conditions, which in the opinion of the investigator, would compromise the safety of the patient or the patient's ability to complete the study. * GEC12: Concomitant malignancies: A diagnosis of a malignancy in the 2 years prior to starting study treatment other than the disease under study. Exceptions include indolent or definitively treated malignancy not expected to require treatment during the study, affect the safety of participants, or affect the endpoints of the trial. * Additional arm specific exclusion criteria as needed by drug arm regimen
