Background: - Immune-based approaches in colorectal cancer have unfortunately with the notable exception of immune checkpoint inhibition in microsatellite instable (MSI-hi) disease been largely unsuccessful. The reasons for this are unclear but no doubt relate to the fact that in advanced disease colorectal cancer appears to be less immunogenic, as evidenced by the lack of infiltrating lymphocytes with advancing T stage - Pexa-Vec (JX-594) is a thymidine kinase gene-inactivated oncolytic vaccinia virus engineered for the expression of transgenes encoding human granulocyte- macrophage colony-stimulating factor (GM-CSF) and beta-galactosidase. Apart from the direct oncolytic activity, oncolytic viruses such as Pexa-Vec have been shown to mediate tumor cell death via the induction of innate and adaptive immune responses - Tremelimumab is a fully human monoclonal antibody that binds to cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) expressed on the surface of activated T lymphocytes and causes inhibition of B7-CTLA-4-mediated downregulation of T-cell activation. Durvalumab is a human monoclonal antibody directed against programmed death-ligand 1 (PD-L1). - The aim of the study is to evaluate whether the anti-tumor immunity induced by Pexa-Vec oncolytic viral therapy can be enhanced by immune checkpoint inhibition. Objective: -To determine the safety, tolerability and feasibility of Pexa-Vec oncolytic virus in combination with immune checkpoint inhibition in patients with refractory metastatic colorectal cancer. Eligibility: - Histologically confirmed metastatic colorectal cancer. - Patients must have progressed on, been intolerant of or refused prior oxaliplatin- and irinotecan-containing, fluorouracil-based, chemotherapeutic regimen and have disease that is not amenable to potentially curative resection. Patients who have a known Kirsten rat sarcoma viral oncogene homolog (KRAS) wild type tumor must have progressed, been intolerant of or refused cetuximab or panitumumab based chemotherapy. - Patients tumors must be documented to be microsatellite-stable (MSS) either by genetic analysis or immunohistochemistry OR microsatellite-high with documented disease progression following anti-programmed cell death protein 1 (PD1)/Programmed death-ligand 1 (PDL1) therapy. - Patients must have at least one focus of metastatic disease that is amenable to pre- and on-treatment biopsy. - Willingness to undergo mandatory tumor biopsy. Design: -The proposed study is Phase I/II study of Pexa-Vec oncolytic virus at two dose levels in combination with immune checkpoint inhibition in patients with metastatic colorectal cancer.
This study is a single center open label phase I study of AZD6738, DNA damage repair/novel cancer agent, in combination with paclitaxel in metastatic cancer patients who have failed standard chemotherapy. AZD6738 is an orally dosed selective and potent inhibitor of Ataxia Telangiectasis and Rad3 Related (ATR) kinase with good selectivity against other Pi3 kinase family members. ATR is a serine/threonine protein kinase and member of the phosphatidylinositol 3-kinase related kinase (PIKK) family. During normal replication, ATR is recruited at stalled replication forks which can progress to double strand breaks if left unrepaired. ATR is also recruited to single strand DNA coated with Replication Protein A (RPA) following single strand DNA damage or the resection of double strand breaks. Recruitment and activation of ATR leads to cell cycle arrest in the S phase while the DNA is repaired and the stalled replication fork resolved, or nuclear fragmentation and entry into programmed cell death (apoptosis). In the clinic ATR inhibitors are expected to cause growth inhibition in tumour cells dependent upon ATR for DNA repair e.g. ATM-deficient tumours. In addition to monotherapy activity, ATR inhibitors are also predicted to potentiate the activity of cytotoxic DNA damaging agents and radiotherapy (through inhibition of ATR-dependent DNA repair processes) when used in combination. While significant enhancement of anti-tumour activity may be achieved, data with AZD6738 suggest the potential need to reduce the ATR inhibitor dose and intensity (relative to monotherapy dose) and introduce dosing breaks to allow normal tissue recovery when used in combination with systemic DNA damaging chemotherapy agents, in order to maintain tolerable therapeutic margins. The mechanism of action of AZD6738 suggests the potential to combine it with a number of anti-cancer treatments, resulting in either synergistic or additive activity. This study is evaluating the safety, tolerability, pharmacokinetics and anti-tumour activity of AZD6738 at increasing doses, in combination with paclitaxel as one of standard salvage regimen in patients with advanced cancer. The study will consist of two parts, each evaluating the safety and tolerability of a specific combination agent, paclitaxel with different drug schedules. An oral formulation of AZD6738 will be used. The PART A will be in combination with paclitaxel; the starting dose of 40 mg AZD6738 OD will be escalated to reach a maximum tolerated dose in patients with advanced solid malignancies, as defined by dose-limiting toxicity. The PART B will be an independent parallel PK expansion cohort with cycle 0 of AZD6738 on D1, D8~D21 monotherapy followed by combination therapy with weekly paclitaxel from cycle 1. Investigators will modify to recruit the minimum or maximum number of patients depending on data generated from other studies using AZD6738.
The Epidermal Growth Factor Receptor (EGFR) is a validated target for the treatment of cancer, and agents targeting EGFR such as erlotinib (Tarceva®) are approved by the FDA for treatment of various solid tumors. AV-412 is a novel inhibitor of the EGFR-tyrosine kinase, with added activity against Her2 and other oncogenic kinases. Based on evidence of preclinical activity in various solid tumors, AV-412 is being developed as a possible novel treatment for cancer in humans. PURPOSE: The purpose of this study is to test the safety and tolerability of AV-412, and determine the maximum tolerated dose of AV-412 when administered orally three times weekly.
This is an open-label, multicenter pilot study in patients with advanced solid tumors. The primary objective of this study is to compare progression-free survival using a treatment regimen selected by molecular profiling with progression-free survival for the most recent regimen the patient has progressed on. To be eligible, patients must have received at least two lines of prior chemotherapeutic, hormonal or biological regimens for advanced disease, have measurable or evaluable, refractory disease and have clear documentation of the time between treatment start and documented progression on the last treatment prior to study entry. Eligible patients must undergo or have available a tumor biopsy for molecular profiling within 2 months of IHC/FISH and/or DNA microarray analysis.
This study will evaluate the tolerance and effects of tariquidar, given in combination with one of three anticancer drugs, for treating solid tumors. Tariquidar works by blocking a pump on a cancer cell. The pump on a cell that prevents anticancer drugs from accumulating is called Pgp (P-glycoprotein). Researchers hope to see whether cancer-fighting drugs can stay in the cells longer. Patients ages 2 to 18 who have solid tumors may be eligible for this study. Tariquidar is infused intravenously (IV) over 30 minutes, given every 21 to 28 days, with one drug that kills cancer cells. Patients are examined by a doctor at least once weekly during treatment and will have routine blood tests twice weekly. They will receive one of the following drugs with tariquidar: doxorubicin (Adriamycin ), vinorelbine (Navelbine ), or docetaxel (Taxotere ). At the first treatment cycle only, there is a baseline Sestamibi scan before treatment and a second one immediately after drug administration. If patients receive tariquidar with doxorubicin, tariquidar is given alone. Then 48 to 72 hours later, the second dose is given, followed by doxorubicin by IV over 15 minutes. Dexrazoxane, which decreases damaging effects of doxorubicin on the heart, is also given by IV over 15 minutes. Granulocyte colony stimulating factor (G-CSF) is injected daily 48 hours after doxorubicin, to alleviate doxorubicin s effect on white blood cells. If patients receive tariquidar with vinorelbine, tariquidar is given alone. Then 48 to 72 hours later, the second dose is given, immediately followed by vinorelbine by IV over 10 minutes; then 1 week later, tariquidar is again given, immediately followed by vinorelbine by IV for 10 minutes. G-CSF is given daily. If patients receive tariquidar with docetaxel, tariquidar is given alone. Then 48 to 72 hours later, the second dose is given, followed by docetaxel by IV over 60 minutes. Drugs to prevent allergic reactions are given before and after each docetaxel dose. G-CSF is given daily. Tariquidar may affect blood pressure during infusion, and there can be reduction of normal blood cells, gastrointestinal problems, and allergic reactions. The radioactive Sestamibi can cause headache, chest pain, and nausea. Radiation used in this study has been approved as involving a slightly greater than minimal risk for adults and an acceptable risk for children. This radiation is considered necessary to obtain information desired. One possible effect is a slight increase in the risk of cancer. This study may or may not have a direct benefit for participants. However, knowledge gained may benefit people with cancer in the future.
