Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Bevacizumab may stop the growth of colorectal cancer by stopping blood flow to the tumor. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus bevacizumab in treating patients who have advanced colorectal cancer.

This is a randomized, placebo-controlled Phase I/II multi-center trial, of the safety and efficacy of Celecoxib in a cohort of 81 HNPCC subjects and gene carriers. The three proposed intervention arms are: Celecoxib (to be provided by Searle) will be administered at 200mg p.o. BID x 12 months or 400mg p.o. BID x 12 months vs. Placebo p.o. BID x 12 months. Assessment of endoscopic and tissue-based biomarker endpoints will be conducted at baseline and 12 months on study drug or placebo. Patients that present with polyps at baseline will undergo a month 4 endoscopy. Plasma drug trough samples for pharmacokinetic analyses will be collected at baseline and month 12. NCI-Chemoprevention Branch will coordinate the efforts and activities of all sites. Safety monitoring will occur via in-patient interviews with exams at month twelve; symptom questionnaires completed at baseline, months one, four, eight and twelve; blood and urinalysis at baseline and at months one, four, eight and twelve. A post-administration telephone call to evaluate side effect resolution will occur at months 13-14 for patients who have unresolved adverse events at the end of month 12.

This protocol will evaluate the activity of 5-Fluorouracil (FUra) given as a 1 hour infusion in combination with leucovorin (LV) and interferon IFN alpha-2a in patients with advanced, measurable colorectal cancer.

This is a Phase II, non-randomized, open-label study to evaluate temozolomide in combination with olaparib in patients with MGMT promoter hypermethylated advanced colorectal cancer.

The purpose of this study is to determine the recommended Phase 2 dose (RP2D) of rivoceranib when used in combination with trifluridine/tipiracil in participants with mCRC and to assess progression-free survival (PFS) in participants with mCRC.

The purpose of this study is to learn if combination of the two drugs regorafenib and nivolumab is an effective treatment for pMMR - MSS colorectal cancer, a special type of cancer of the colon or rectum (pMMR stands for proficient Mismatch Repair; MSS stands for Microsatellite Stable) and whether it is safe for patients. Regorafenib works by blocking several different proteins involved in tumor growth. Nivolumab is an immunotherapy drug encouraging the body's own immune system to attack cancer cells. Both drugs have been approved, but not for how they are being used as combination therapy in this study. Brand name of regorafenib is Stivarga; brand name of nivolumab is Opdivo.

The aim of this explorative phase II clinical trial is to establish the safety and efficacy of intratumoral influenza vaccine in patients with colorectal cancer, as an additive treatment prior to intended curative surgery.

Background: Metastatic or refractory/recurrent small bowel and colorectal cancers cannot be cured and are often not helped by standard treatments. Researchers want to find better treatments by testing a combination of drugs. Objective: To learn if a new combination of immunotherapy drugs can shrink tumors in people with advanced small bowel and colorectal cancers. Eligibility: People ages 18 and older who have advanced metastatic or refractory/recurrent small bowel and/or colorectal cancer Design: Participants will be screened on a separate protocol. They will have a physical exam and medical history. They will have imaging scans. They will have blood and urine tests. Their heart function will be measured. They may have a tumor biopsy. Participants will repeat some of the screening tests during the study. Participants will be put into study groups. Each group will get a combination of the following drugs: CV301 vaccine (MVA-BN-CV301 and FPV-CV301), M7824, and N-803. Some will also get NHS-IL12. Participants will get the CV301 vaccines by injection under the skin. They will get M7824 by intravenous infusion every 2 weeks. They will get N-803 by injection under the skin every 2 or 4 weeks. They may get NHS-IL12 by injection under the skin every 4 weeks. They will take the study drugs for up to 1 year. They will visit the NIH every 2 weeks. After treatment ends, participants will go to the clinic for a 28-day follow-up visit or have a telephone call. They will be contacted every 3 months for 1 year, and then every 6 months after that for the rest of their life.

Chronic rhinosinusitis with nasal polyposis (CRwNP) is an inflammatory disease of the nasal mucosa. It is presented with severe stuffiness, nasal discharge, facial pressure/pain, and sleep disorders. It leads to severe inconvenience to social life and the quality of life. The first step standard medical therapy consists of the topical intranasal or systemic corticosteroids. Surgery should be considered in the case of medical treatment failure. However, the recurrences are common after both surgery and medical therapies in severe disease and usually require revision surgeries or high dose corticosteroid regimens. On the contrary, either the revision surgeries or the high dose corticosteroid therapies are not capable of preventing the recurrences, treatment failures. Besides, revision surgeries usually lead to high complication rates and high dose corticosteroids usually cause severe adverse effects. The use of the short course topical intranasal corticosteroids after the surgery is generally advocated for these patients. However, the recurrence rates are still high. Hence a new and effective maintenance treatment algorithm with no severe adverse effects is required. The hypothesis of the clinical trial is an estimated symptom recovery and superiority in both efficacy and safety by the use of low-dose methylprednisolone or methotrexate as compared to the standard maintenance therapy in treatment-resistant CRwNP patients. Therefore, the results of the present study are believed to provide data on novel maintenance therapy and suggest an alternative to the topical intranasal corticosteroids or the high-risk revision surgery.

This is a multi-center, prospective, non-interventional real-world study. In a real-world environment, in line with the current status of the domestic diagnosis and treatment process, and on the premise of not increasing the burden of patients and medical resources, we explore the best indicators for predicting the outcome of patients with Clinical Research Coordinator (CRC) after surgery. The inclusion criteria for patients are perioperative patients with CRC. Real-world data analysis were conducted to determine whether immunization interventions versus non-interventions were able to improve patients' clinical outcomes (OS, PFS).
