Filter by:This phase Ib/II trial studies the side effects and best dose of guadecitabine when given together with nivolumab and to see how well they work in treating participants with colorectal cancer that does not respond to treatment and has spread to other places in the body. Drugs used in chemotherapy, such as guadecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread. Giving guadecitabine and nivolumab may work better in treating participants with colorectal cancer.
This trial studies nutritional preferences and product accessibility in oral nutritional supplements in participants with breast, colorectal, upper gastrointestinal, or prostate cancer. Learning what participants like and dislike about their current or past used nutritional supplements may help doctor know how to improve them.
The role of radiotherapy in metastatic cancer has historically been limited to palliation while metastasectomy or radiofrequency has emerged as playing a major role in disease control. Although resection is the standard of care for liver metastasis, 80-90% of patients are not resectable at diagnosis in particular because of the presence of oligometastases. Factors that favour a truly oligometastatic state include a long latent interval between the treatment of the primary tumor and the appearance of metastases. Oligometastatic cancer is a very heterogeneous disease with respect to several factors including the location of the primary tumor. With the advent of extracranial stereotactic body radiation therapy (SBRT), higher biological equivalent doses can be safely delivered in 3 to 5 fractions, thus potentially ablating all the tissue in the treated area while protecting more efficiently the hosting organ and healthy tissues surrounding the tumors. In patients with liver oligometastases, in-field local control rates at 2 years range from 70% to 90% with less than 5% severe grade 3 or higher toxicity rates. Retrospective studies indicate that roughly 20% of the patients remain disease-free 2 to 4 years after SBRT. For patients treated with SBRT some authors found that half of the patients had either no metastatic progression or very little progression in terms of number and site of metastases. The patterns of failure after SBRT for oligometastases in one organ showed that 73% of patients eventually developed new metastases with higher than 80% occurring as new metastases in the same index organ. These findings support the idea of an oligometastatic state in which aggressive local therapy could improve progression-free survival (PFS). With this phase III study, we sought to evaluate the impact of SBRT on PFS at 2 years in patients with synchronous or metachronous liver-only oligometastases from colorectal cancers patients after a first line chemotherapy for metastatic disease but not having progressed during first line chemotherapy and up to 1 year
This is a phase II Randomized comparison clinical trial of activated CIK armed with anti-CD3-MUC1 bispecific antibody for advanced colorectal cancer. And the aim of this research is to study the clinical efficacy and safety of activated CIK armed with anti-CD3-MUC1 bispecific antibody for colorectal cancer.
The primary objective of this multicenter, prospective, randomized study is to evaluate the performance of Pure-Vu System in cleansing patients' colon who are indicated for a colonoscopy procedure using one of two different reduce bowel preparation regimes.in addition, the cecum intubation rate, time to cecum, total procedure time, and adverse event will be evaluated.
Part I of this study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of galunisertib/capecitabine as second line treatment in patients with 5-FU or capecitabine resistant CRC. Part II is designed to obtain proof of principle of the galunisertib plus capecitabine combination in patients with chemo-resistant CRC. The combination of galunisertib plus capecitabine will be given as second line therapy in the phase II part of this study. Patients with chemotherapy resistant activated TGF-β signature-like tumors will have received a fluoropyrimidine (5FU or capecitabine) in the first line of chemotherapy, usually combined with oxaliplatin and, depending upon local hospital preferences or national guidelines, also bevacizumab, or cetuximab/panitumumab if the tumor is KRAS wild type. Addition of galunisertib to capecitabine should thus result in reversal of unresponsiveness, which is the first step in exploring this concept in the clinic. Capecitabine can be used as single agent in advanced CRC and is thus attractive for this study concept. If proof of principle is achieved also other tumor types can be explored with this genetic makeup, such as non-small cell lung cancer (NSCLC) in second line of treatment after platinum doublet therapy in first line, usually cisplatin/carboplatin-pemetrexed in non-squamous and cisplatin/carboplatin-gemcitabine or cisplatin/carboplatin-paclitaxel in squamous type NSCLC.
Phase I Study of biweekly combination therapy with S-1, Irinotecan, and Bevacizumab as 1-line Chemotherapy in Patients With Advanced Colorectal Cancer.
This study is for patients with metastatic colorectal cancer who are candidates for resection of metastases. This study will be conducted sequentially with 2 cohorts: 1.) Monotherapy Cohort and 2.) Combination Cohort Pre-metastatectomy - Monotherapy Cohort: The first 10 subjects will receive Atezolizumab 840 mg IV on Day 1 and Day 15 of each 28-day cycle. - Combination Cohort: The next 15 subjects will receive Atezolizumab 840 mg IV on Day 1 and Day 15 and Cobimetinib 60 mg PO on Days 1-21 of each 28-day cycle. Note: Cobimetinib must be held for the 7 days prior to metastatectomy. All subjects will be treated for 2 cycles (8 weeks) prior to metastatectomy Metastatectomy Subjects will undergo liver metastatectomy within 42 days of completion of Cycle 2 of pre-metastatectomy treatment. No study treatment is administered while the patient is healing after surgery. Post-metastatectomy Once the patient has healed from the surgery, adjuvant treatment may be administered at the discretion of the treating physician. Restaging following standards of care for this setting.
This study has two portions. The main goal of the Phase Ib portion of this research study is to see at what time Yttrium-90 (Y-90) radioembolization therapy and nivolumab can safely be given to patients without having too many side effects. Other purposes of this research study will be to study any tumor responses. The Phase II portion of the study will test how many patients show shrinkage in their tumor with this combination of medicines and what changes occur inside the cancer cells and blood cells after treatment. The study team will pick the part of the study each subject participates in. Y-90 radioembolization therapy is minimally invasive procedure that combines two types of therapy (embolization which blocks certain blood vessels, and radiation therapy, which kills cancer cells) to treat cancer tumors in the liver. This works with tiny glass or resin beads filled with the radioactive isotope yttrium-90 (Y-90). They are placed inside the blood vessels that feed the tumor in the liver. This blocks the supply of blood to the cancer cells and delivers a high dose of radiation to the tumor while sparing normal tissue. Nivolumab is an FDA approved medicine that is used for the treatment of different types of cancers and metastases (second growths from cancer).
This will be a pilot study involving 5 patients diagnosed with colorectal carcinoma and treated with pre-operative chemotherapy and external beam radiation therapy at the Jewish General Hospital, whom will very soon undergo surgery. Participants will be sensitized by the instillation of a 250 mL enema containing 1.6 mmol of HAL. The enema will be administered with a plastic tube with an inflatable blocking balloon to prevent leakage of the enema. Fluorescence sigmoidoscopy will be performed with white light then blue excitation light after retention of the enema for 60 minutes, followed by a rest time of up to 30 minutes before rectoscopy. Red fluorescence should be induced by illumination with blue light. Pictures with and without fluorescence will be taken. The patients will undergo a colectomy (partial or complete) within the next 2-3 days and the surgical specimens will be collected for further fluorescence microscopy studies and pathological correlation of fluoresce with malignant pathology/histology as the gold standard. The total concentration of porphyrins in the patients' urine and serum will be recorded before sensitization, immediately after sensitization (instillation of the enema), and approximately 24 hours after sensitization. The patients' pre-and-post operative liver function tests will be measured. Adverse events will be reported by direct questioning of all patients with regards to photosensitivity and gastrointestinal symptoms (nausea, vomiting), and by measuring blood pressure and heart rate. Our objectives and endpoints are: 1) to determine if fluorescence with photodynamic diagnostics is selective for colorectal cancer, 2) to determine if photodynamic diagnostics has the potential to improve the detection of malignant cell after neoadjuvant chemotherapy and radiation, and 3) to determine if photodynamic diagnostics can provide an accurate depiction of the extent of disease burden not visible with normal white light sigmoidoscopy to the naked human eye.
