Details and patient eligibility

About

This study is being done to collect tissue samples to test how accurately a tumor response platform, Elephas, can predict clinical response across multiple types of immunotherapies, chemoimmunotherapy and tumor types.

Enrollment: 324 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Subjects must meet one of the following criteria:

• Subjects suspected of or diagnosed with the following Stage IV/metastatic or recurrent malignancies:

  • Lung: Non-small Cell Lung Cancer (NSCLC)
  • Skin: Cutaneous Malignancy, excluding Uveal Melanoma
  • Esophageal Cancer
  • Cervical Cancer
  • Endometrial Cancer
  • Colon Cancer: Mismatch repair deficient (dMMR) CRC only
  • All solid tumors with high tumor mutation burden (TMB)
  • All solid tumors that are microsatellite instability high (MSI-H)
  • All mismatch repair deficient (dMMR) solid tumors
  • Liver Cancer
  • Any solid tumor with measurable disease that is eligible for pure ICI therapy or that the clinician plans to treat with immune checkpoint inhibitor (ICI) therapy. NOTE: This can be in the setting of a trial, compassionate use, or the use of appropriate laboratory developed tests (LDTs) that, per clinician, render the patient eligible for ICI therapy, either frontline or a later line.

OR

• Subjects suspected of or diagnosed with the following Stage III per provider discretion or IV/metastatic malignancies:

  • Kidney: Clear Cell Renal Cell Carcinoma (ccRCC)
  • Bladder: Urothelial Carcinoma (UC)
  • Any solid tumor with measurable disease that is eligible for pure ICI therapy or that the clinician plans to treat with ICI therapy. NOTE: This can be in the setting of a trial, compassionate use, or the use of appropriate LDT tests that per clinician, render the patient eligible for ICI therapy, either frontline or a later line

OR

• Patients who will be receiving neoadjuvant CPI for the following resectable early-stage malignancies:

  • Breast Cancer: Triple negative breast cancer (TNBC)

  • Lung: Non-small cell lung cancer (NSCLC)

    • NOTE: Patients with suspected NSCLC who would be eligible for neoadjuvant checkpoint inhibitor (CPI) are eligible to enroll per provider discretion

  • Any solid tumor that is eligible for pure ICI therapy or that the clinician plans to treat with ICI therapy. NOTE: This can be in the setting of a trial, compassionate use, or the use of appropriate LDT tests that per clinician, render the patient eligible for ICI therapy, either frontline or a later line

• LOCALLY ADVANCED/METASTATIC PATIENTS: Measurable disease as defined per protocol NOTE: Tumor lesions in a previously irradiated area are not considered measurable disease; Disease that is measurable by physical examination only is not eligible.

• NEOADJUVANT PATIENTS: Subjects must be eligible based on investigator discretion to receive approved CPI therapy.

• Subjects who are newly diagnosed or have suspected cancer must be treatment-naïve at the time of biopsy.

• Subjects who are Stage I, II, or III and have progressed to metastatic cannot have received any anti-cancer treatment for at least 2 - 4 weeks (depending upon the washout period of prior anti-cancer treatment) prior to biopsy as per the agents used.

• ECOG Performance Status (PS) 0, 1 or 2.

• Negative pregnancy test done ≤7 days prior to enrollment, for persons of childbearing potential only

• Female subjects must not be pregnant or breastfeeding and must use appropriate methods of contraception when applicable.

• Subjects must be clinically able, at investigator discretion, and willing to undergo either:

  • additional biopsy passes during their standard of care biopsy, OR
  • a biopsy for research only, if applicable.
  • NOTE: These additional biopsies may either be collected from the primary tumor or a metastatic site amenable to biopsies per the clinician.

• Subjects with a known secondary cancer diagnosis are eligible to participate if participation does not interfere with systemic anti-cancer standard of care treatment for suspected primary diagnosis.

• Provide written informed consent

Exclusion criteria

• Pregnant women because this study involves a greater than minimal risk procedure (biopsy)

• Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety for the biopsy

• Immunocompromised patients and patients known to be HIV positive and currently receiving antiretroviral therapy

  • NOTE: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial

• Uncontrolled intercurrent illness including, but not limited to:

  • ongoing or active infection
  • psychiatric illness/social situations that would limit compliance with study requirements

• Subjects who are enrolled or plan to be enrolled in a blinded cancer therapeutic treatment trial

Trial design

324 participants in 1 patient group

Observational

Description:

Patients undergo tissue biopsy and may optionally undergo blood sample collection and have their medical records reviewed on study. Patients receive standard treatment with checkpoint inhibitors during the study and undergo standard tumor assessments during screening and follow-up.

Treatment:

Procedure: Biospecimen Collection

Procedure: Tissue Collection
