QUILT-3.055: A Study of Combination Immunotherapies in Patients Who Have Previously Received Treatment With Immune Checkpoint Inhibitors

QUILT-3.055 is a Phase 2b, open-label, multicohort study investigating combination immunotherapies in patients with advanced solid tumors who have previously been treated with PD-1/PD-L1 checkpoint inhibitors. The study aims to evaluate the safety and efficacy of NAI (nogapendekin alfa inbakicept) in combination with other agents like checkpoint inhibitors and cell therapies across various cancer types and treatment settings. The study includes multiple cohorts based on prior therapies and cancer types, with a focus on assessing overall response rate (ORR), overall survival (OS), and other measures of anti-tumor activity and immune response.

National Cohort of Colorectal Cancers With Microsatellite Instability

The three main pathways of colorectal carcinogenesis are chromosomal instability, microsatellite instability (MSI) (15% of colorectal cancers =CRCs) and CpG island methylator phenotype (CIMP). MSI CRCs are associated with a better prognosis after curative surgery than CRCs without microsatellite instability (MSS). In contrast, MSI CRCs do not appear to benefit from adjuvant 5-FU chemotherapy, unlike patients with MSS CRCs. Nevertheless, the benefit of adjuvant chemotherapy with FOLFOX seems to be retained. The identification of prognostic markers in this subgroup of patients is therefore essential to decide on adjuvant chemotherapy, the efficacy of which is currently debated in MSI CRC. To date, there are very few data concerning metastatic MSI CRC. Metastatic forms are rare (about 5% of metastatic CRCs), but are thought to be associated with chemoresistance and poor prognosis. Nevertheless, data are very sparse and there are no data regarding the use of modern chemotherapies and targeted therapies in metastatic MSI CRC. Thus, it is important to characterize the chemosensitivity of metastatic forms. Clinical predictors of recurrence after curative CRC surgery are known but have only been studied in MSI CRC retrospectively. Similarly, many molecular and immunohistochemical factors, prognostic or predictive of response to adjuvant chemotherapy, have been recently identified in CRC (KRAS, BRAF, TP53, PI3KCA mutations, CIMP phenotype, SMAD4, immune response...). Most of these markers have been studied in all CRCs, but not specifically in the MSI CRC subgroup. All these prognostic and/or predictive biomarkers need to be better characterized in a large cohort of MSI CRCs.

Adoptive Transfer of Tumor Infiltrating Lymphocytes for Advanced Solid Cancers

This is a Phase 2 study to evaluate the efficacy of a non-myeloablative lymphodepleting preparative regimen followed by infusion of autologous TIL and high-dose aldesleukin in patients with locally advanced, recurrent, or metastatic cancer associated with one of the following cancer types: 1.) gastric/esophagogastric, 2.) colorectal, 3.) pancreatic, 4.) sarcoma, 5.) mesothelioma, 6.) neuroendocrine, 7.) squamous cell cancer, 8.) Merkle cell, 9.) mismatch repair deficient and/or microsatellite unstable cancers, and 10.) patients who have exhausted conventional systemic therapy options by using the objective response rate (ORR).

TremelImumab aNd Durvalumab For the Non-operatIve Management (NOM) of MSI-high Resectable GC/GEJC.

INFINITY is a Phase II, multicentre, single-arm, multi-cohort trial aimed at evaluating the activity and safety of the combination of tremelimumab and durvalumab as neoadjuvant (Cohort 1) and definitive (Cohort 2) treatment for MSI-high gastric/gastroesophageal juction cancer patients eligible for radical surgery.
