Active clinical trials for "Colorectal Neoplasms"

This is a multicenter, open label Phase 1b/2 study in patients with metastatic colorectal carcinoma. The Phase 1b will identify the dose of the combination of PF-05212384 plus FOLFIRI. The randomized, two-arm Phase 2 portion will compare the efficacy and safety of PF-05212384 plus FOLFIRI to that of bevacizumab plus FOLFIRI. The study population will consist of patients with mCRC previously treated with an oxaliplatin-based regimen in the first line setting or who have progressed within 6 months of the end of an adjuvant oxaliplatin-based regimen.

The purpose of this study is to determine the efficacy and safety of Andrographolides combined with Capecitabine in treatment of elderly patients with locally advanced or recurrent or metastasis inoperable colorectal cancer

This is a Phase II multi-center exploratory study to identify biomarkers predictive of clinical response to aflibercept in patients with metastatic colorectal cancer who have failed first-line therapy, consisting of an oxaliplatin-containing regimen in combination with bevacizumab. Patients will consent to a needle core biopsy of a liver metastatic lesion prior to starting treatment and blood samples will be collected from study patients during treatment. An exploratory pharmacoeconomic analysis will be performed to evaluate productivity loss, quality of life and resource utilization while on treatment with aflibercept.

Colorectal cancer patients with metastases (mCRC) at response under expensive chemotherapy which may be toxic +/- exhausting are candidates for an effective and more convenient maintenance treatment. Objectives: To define the efficacy of maintenance chemotherapy by a low-dose metronomic (LDM) regimen, in metastatic CRC patients responding under FOLFIRI + bevacizumab. To discover predictive factors for response to this LDM regimen. Hypothesis: The re-growth of residual metastases can be slowed by the anti-angiogenic effects of LDM chemotherapy. Serial measurements of angiogenic/ inflammatory factors in the plasma and/or evaluation of certain enzymes in the tumor may discover predictive factors of response to LDM chemotherapy in metastatic CRC patients.

The purpose of this study is to investigate the effects of short term oral Metformin therapy on biomarkers for tumor growth in subjects with newly diagnosed colon or rectal adenocarcinoma. It is hypothesized that there are independent actions of Metformin on the outcome of subjects with colorectal cancer (CRC). Also hypothesized is that metformin effects on CRC cell growth will correlate with this drug's effects on markers mentioned above, because the markers are closely related to tumor growth and metastases.

T Cell Receptor Based Therapy of Metastatic Colorectal Cancer With mRNA-engineered T Cells Targeting Transforming Growth Factor Beta Receptor Type II (TGFβII)

This is a pilot study to assess the safety and tolerability, as well as the immune response rate, of mDC3 vaccine in patients with colorectal cancer.

Background: Colorectal cancer is a common cancer in the Unites States (U.S.) It causes the second most cancer-related deaths. The drug avelumab and vaccine Ad-CEA together help the immune system fight cancer. Objective: To test if avelumab and Ad-CEA plus standard therapy treats colorectal cancer that has spread to other sites better than standard therapy alone. Eligibility: People ages 18 and older with untreated colorectal cancer that has spread in the body Design: Participants will be screened with: Test to see if their cancer has a certain deficiency Blood, urine, and heart tests Scans Medical history Physical exam Tumor sample. This can be from a previous procedure. A small group of participants will get Ad-CEA and avelumab plus standard therapy. This is leucovorin calcium (folinic acid), fluorouracil, and oxaliplatin (FOLFOX) plus bevacizumab for up to 24 weeks then capecitabine plus bevacizumab. The others will have treatment in 2-week cycles. They will be Arm A or B: Arm A: FOLFOX and bevacizumab by intravenous (IV) days 1 and 2 for 12 cycles. After that, capecitabine by mouth twice a day and bevacizumab by IV on day 1. Arm B: Ad-CEA injection every 2-12 weeks. Avelumab by IV on day 1 of each cycle. FOLFOX and bevacizumab by IV days 2 and 3 for 12 cycles. Then, capecitabine by mouth twice a day and bevacizumab through IV on day 2. Participants will repeat screening tests during the study. Participants will be treated until their disease gets worse or they have bad side effects. Arm A participants can join Arm B. They will have a visit 4 5 weeks after they stop therapy.

A-REPEAT (Anti-Epidermal Growth Factor Receptor -EGFR- rechallenge and plasma genotyping of patients with advanced colorectal tumors) is a Greek, investigator-initiated, single arm open-label phase II study of anti-EGFR therapy rechallenge in combination with chemotherapy in patients with advanced colorectal cancer. Patients with a metastatic, histologically proven colorectal carcinoma RAS wild type will be treated with a combination of panitumumab and third-line irinotecan-based or oxaliplatin-based chemotherapy (FOLFOX,FOLFIRI or irinotecan monotherapy).

The study is divided into two parts. The first part of the study will test various doses of ASN003 to find out the highest safe dose to test in three specific groups. The second part of the study will test how well ASN003 can control cancer. Subjects will be enrolled into one of three groups. Group 1: metastatic or recurrent melanoma with documented BRAFV600 mutation (n=20 evaluable patients) Group 2: metastatic colorectal cancer (CRC), or advanced non-small cell lung cancer (NSCLC) with documented BRAFV600 mutation (n=14 evaluable patients) Group 3: advanced solid tumors with documented PI3K pathway alterations (PIK3CA mutation or PTEN loss) (n=14 evaluable patients)
