Overview
The primary objective of this study is to determine the ex-vivo prognostic accuracy of the Cybrid live tumor diagnostic platform across a basket of solid tumors, using in-vivo RECIST 1.1 as the reference method.
Description
Cancer is a leading cause of death and despite many new drugs, a major diagnostic challenge remains knowing which drug will work best for a patient. A new class of drugs called checkpoint inhibitors (CPIs) have revolutionized cancer treatment. However, current diagnostic methods (e.g. PDL1, MSI and TMB) do not accurately predict which patients will respond.
Elephas is developing a diagnostic platform using small 3D Live Tumor Fragments (LTFs) from participants for accurate prediction of drug response with a focus on CPIs such as Pembrolizumab (Keytruda). These LTFs contain both tumor cells and infiltrating immune cells, which are critical in determining response to CPIs and other immunotherapies.
In this observational clinical basket trial, participants will be recruited and their actual clinical response (using RECIST 1.1) to CPIs across five solid tumors (lung, head/neck, bladder, kidney, and skin) will be compared to the platform's predictive Artificial Intelligence (AI) score that is based on RNA, clinical data, and 3D microscopy images. The sensitivity and specificity of the platform's score will be determined and compared to current diagnostic methods for CPIs like PDL1, MSI, and TMB.
Eligibility
- 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 Stage III or IV:
- Bladder: Urothelial Carcinoma (UC)
- Kidney: Clear Cell Renal Cell Carcinoma (ccRCC)
- Subjects suspected or diagnosed with Stage IV/metastatic:
- 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
- Lung: Non-small cell lung cancer (NSCLC)
- Skin: Cutaneous Melanoma, excluding Uveal Melanoma
- Uterus: endometrial cancer
- Subjects suspected or diagnosed with:
- Any metastatic solid tumor with high TMB, MSI-High or dMMR and are being considered for treatment with ICI therapy.
- Any metastatic solid tumor that the clinician plans to treat with ICI
therapy. NOTE: This can be either 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. 4. Subjects must be clinically able, at investigator discretion, to undergo additional
core needle or forceps biopsy passes during their biopsy.
5. Subjects who are newly diagnosed or have suspected cancer must be treatment-naïve atthe time of biopsy. All other subjects should have the biopsy performed before starting their next line of treatment.
6. Subjects with a newly confirmed diagnosis who have previously undergone a standard ofcare biopsy must be willing to undergo a separate biopsy procedure solely for the purposes of this study.
7. Female subjects must not be pregnant. 8. Subjects with a known auto-immune disease that would render them ineligible forimmune-oncology treatment are not eligible.
9. Immunocompromised subjects, and subjects known to be HIV positive and currentlyreceiving antiretroviral therapy are not eligible. NOTE: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial.
10. Subjects who are enrolled or plan to be enrolled in a blinded oncology treatment trialare not eligible.
- Subjects suspected or diagnosed with Stage III or IV:
