Active clinical trials for "Microsatellite Instability"

This study will assess the safety and efficacy of DPX-Survivac and low dose cyclophosphamide with pembrolizumab in subjects with selected advanced and recurrent solid tumours.

A multicenter open-label phase 1/1b study to evaluate the safety and preliminary efficacy of SO-C101 as monotherapy and in combination with pembrolizumab in patients with selected advanced/metastatic solid tumors

The main purpose of this study is to assess the efficacy and safety of IBI310 in combination with sintilimab in patients with Microsatellite Instability High (MSI-H) or Mismatch Repair Deficient (dMMR) locally advance or metastatic colorectal cancer.

In this open-label phase II study, patients will be scheduled for neoadjuvant treatment with PD-1 inhibitors (Camrelizumab) plus VEGF inhibitor (Apatinib) for dMMR/MSI-H colorectal cancer staged as locally advanced (cT3-4N+/-M0 for rectal cancer, cT4 or cT3 with extramural extension ≥5mm for colon cancer). Radiological evaluation will be preformed after 4 cycles of treatment. Patients (either with colon or rectal cancer) who achieve complete clinical response will be offered the choice of Watch & Wait.

In this study, MMRd metastatic colorectal cancer (mCRC) patients who failed standard therapies will undergo treatment with pembrolizumab, while RAS-extended mutated MMR-proficient mCRC patients will be tested for o6-methylguanine-DNA-methyltransferase (MGMT) expression (IHC) and then for MGMT promoter methylation. MGMT IHC-negative, promoter methylation positive patients will be treated with temozolomide (TMZ). Patients progressing under temozolomide will be tested for tumor mutational burden (TMB) and proceed to pembrolizumab if TMB is > 20 mutations/Mb. The primary study hypothesis is that tumors with acquired resistance to temozolomide become hypermutated and are sensitive to pembrolizumab.

This phase Ib/II trial studies how well anti-PD-L1/TGFbetaRII fusion protein M7824 (M7824) works in treating patients with colorectal cancer (or with other solid tumors with microsatellite instability) that has spread to other places in the body or cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as M7824, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This is a Phase IIb, multicohort, open-label multicenter study of combination immunotherapies in patients who have previously received treatment with PD-1/PD-L1 immune checkpoint inhibitors. All patients in Cohorts 1-4 will receive the combination treatment of PD-1/PD-L1 checkpoint inhibitor plus N-803 for up to 17 cycles. Each cycle is six weeks in duration. Some patients who experience disease progression while on study in Cohorts 1-4 may roll over into Cohort 5 and receive combination therapy with a PD-1/PD-L1 checkpoint inhibitor, N-803, and PD-L1 t-haNK cellular therapy for up to an additional 17 cycles. Each cycle is six weeks in duration. All patients will receive N-803 once every 3 weeks. Patients will also receive the same checkpoint inhibitor that they received during their previous therapy. Radiologic evaluation will occur at the end of each treatment cycle. Treatment will continue for up to 2 years, or until the patient experiences confirmed progressive disease or unacceptable toxicity, withdraws consent, or if the Investigator feels it is no longer in the patient's best interest to continue treatment. Patients will be followed for disease progression, post-therapies, and survival through 24 months past administration of the first dose of study drug.

This study evaluates whether it is safe to Focused Ultrasound Ablation (FUSA) treatments with and without PD-1 blockade and with and without intratumoral poly-ICLC. A device called the Echopulse will be used for the FUSA therapy. Patients will be assigned to 1 of 2 cohorts depending on their disease and treatment status. In Cohort 1, patients will receive FUSA therapy while receiving PD-1 blockade therapy as part of standard clinical care treatment. In Cohort 2, patients who discontinue or are ineligible for PD-1 blockade therapy will undergo FUSA without concurrent systemic therapy, with the goal of utilizing the FUSA to boost the innate immune response. The optional secondary regimen will combine FUSA (+/- PD-1 blockade) with intratumoral poly-ICLC.

This is a Phase 2, non-randomised, open-label, multicentric study to investigate the efficacy and safety of nivolumab monotherapy in 6 cohorts of patients with specific rare cancers who have unresectable locally advanced or metastatic disease, which is resistant or refractory to standard therapy, or for which standard therapy does not exist, or is not considered appropriate, and for which no other experimental treatment options are available.

The main purpose of this study is to evaluate the safety and tolerability of anti-programmed cell death ligand 1 (PD-L1) checkpoint antibody LY3300054 in participants with advanced refractory solid tumors.
