Outcome Measures

Primary Outcomes (1)

  • Determine Ex-Vivo Prognostic Accuracy of Elephas Platform

    The ex-vivo prognostic accuracy of the Elephas live tumor diagnostic platform will be determined using in-vivo RECIST 1.1 as the reference method.

    3 years

Secondary Outcomes (1)

  • Establish AUC of ELEPHAS Score and Compare with FDA Approved Biomarkers

    3 years

Study Arms (1)

Patients with suspected or diagnosed cancer types as listed in the description

Subjects suspected or diagnosed with recurrent, locally advanced or metastatic cancer: bladder (urothelial carcinoma), kidney (ccRCC). Subjects suspected or diagnosed with recurrent or metastatic cancer: Colon and Rectum (MSI-H/dMMR Colorectal Cancer), Head and Neck (Squamous Cell Carcinoma), liver (Hepatocellular Carcinoma), Lung (NSCLC), Skin (Cutaneous Melanoma), Uterus (endometrial cancer). Subjects suspected or diagnosed with one of the following cancer types eligible for pure ICI neoadjuvant therapy: Skin (Cutaneous Melanoma, Stage III) Subjects suspected or diagnosed with: Any solid tumor type that is eligible for pure ICI therapy in the neoadjuvant or advanced/metastatic setting; Any metastatic solid tumor with high TMB, MSI-High or dMMR and are being considered for treatment with ICI therapy; Any recurrent or metastatic patient with a solid tumor that the clinician plans to treat with ICI therapy.

Procedure: Core Needle Biopsy, Forceps Biopsy, Punch Biopsy

Interventions

Subjects must be clinically able, at investigator discretion, to undergo additional core needle biopsy, forceps biopsy, or punch biopsy passes during their biopsy. These additional biopsies may either be collected from the primary tumor or a metastatic site amenable to additional passes (e.g., liver or lymph nodes) per the clinician.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adults aged 18 years or older, able to provide informed consent, and have a suspected or confirmed cancer diagnosis that meets requirements outlined in the eligibility criteria above.

You may qualify if:

  • Written informed consent and HIPAA authorization for release of personal health information prior to registration. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
  • Age ≥ 18 years at the time of consent.
  • Subjects must meet one of the following criteria:
  • Subjects suspected or diagnosed with recurrent, locally advanced or metastatic cancer:
  • Bladder: Urothelial Carcinoma (UC)
  • Kidney: Clear Cell Renal Cell Carcinoma (ccRCC)
  • Subjects suspected or diagnosed with recurrent or metastatic cancer:
  • Colon and Rectum: Microsatellite instability-high (MSI-H)/deficient mismatch repair (dMMR) Colorectal Cancer (CRC)
  • Head and Neck: Squamous Cell Carcinoma (HNSCC), excluding nasopharyngeal and salivary gland cancers
  • Liver: Hepatocellular Carcinoma
  • Lung: Non-small cell lung cancer (NSCLC)
  • Skin: Cutaneous Melanoma, excluding Uveal Melanoma
  • Uterus: endometrial cancer
  • Subjects suspected or diagnosed with one of the following cancer types eligible for pure ICI neoadjuvant therapy:
  • o Skin: Cutaneous Melanoma, Stage III
  • +6 more criteria

You may not qualify if:

  • Subjects who are pregnant
  • Subjects with a known auto-immune disease that would render them ineligible for immune-oncology treatment
  • Immunocompromised subjects, and subjects known to be HIV positive and currently receiving antiretroviral therapy
  • Subjects who are enrolled or plan to be enrolled in a blinded oncology treatment trial
