Filter by:This is a Phase 1, open-label, dose escalation and expansion study of MT-8421 (an Engineered Toxin Body (ETB)) as monotherapy and in combination with nivolumab in patients with selected advanced solid cancer types. MT-8421 is an investigational drug that specifically targets and depletes cytotoxic T-lymphocytes-associated protein 4 (CTLA-4) expressing cells in an effort to directly dismantle the tumor microenvironment for the treatment of patients with advanced solid tumors.
This is an open-label, non-randomized, Phase 1b/2 study to determine the safety and tolerability of NC410 when combined with a standard dose of pembrolizumab. This study will also assess the clinical benefit of combination therapy in participants with advanced unresectable and/or metastatic ICI refractory solid tumors OR ICI naïve MSS/MSI-low solid tumors
In this study, we aimed to identify the different histopathological features of tumors with microsatellite instability (MSI) compared to microsatellite stable (MSS) in patients who underwent surgery for colorectal cancer. We also planned to determine how MSI affects prognostic parameters.
This is a first-in-human, phase 1a/1b, multicenter, open-label, dose escalation study of STK-012 as monotherapy and in combination with pembrolizumab in patients with selected advanced solid tumors.
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.
Deficient mismatch repair (dMMR) or microsatellite instability high (MSI-H) accounts for 4-5% in metastatic colorectal cancer (mCRC). The efficacy and survival of patients with dMMR/MSI-H status received palliative chemotherapy have not clear yet. In this study, the investigators observed the efficacy and survival of dMMR/MSI-H status mCRC patients received palliative first-line chemotherapy.
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
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.
To determine if the out-of-field ORR is improved with the addition of radiation therapy to anti-PD-1 for patients with MSI-H/dMMR metastatic solid tumors. Determine the rates of in-field tumor control, disease control (stable disease, partial response, complete response), durability of disease response, progression-free survival, overall survival, and to assess quality of life and toxicity. Determine the chronology and profile of the radiation-associated immune response.
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.
