Active clinical trials for "Colorectal Neoplasms"

The purpose of this study is to assess the efficacy and safety of treatment with FOLFIRI-aflibercept compared to initial treatment with FOLFIRI-aflibercept (for 6 cycles) followed by maintenance with 5FU-aflibercept, in an elderly population with metastatic colorectal cancer (mCRC) after failure of an oxaliplatin-based regimen

AVETUX is a single arm multicentric phase II investigator initiated trial conducted by the Arbeitsgemeinschaft Internistische Onkologie (AIO) in 11 German sites in patients with previously untreated RAS/BRAF wildtype mCRC independent of MSI status.

This study is single center single arm prospective phase II study. In this study, efficacy and side effects of pemetrexed as salvage regimen on patients who failed all standard chemotherapy and total of 29 patients will be enrolled. Pemetrexed will be continued until disease progression is happened.

This was a phase Ib study of PDR001 in combination with regorafenib in adult patients with previously treated metastatic microsatellite stable (MSS) colorectal cancer. The study assessed primarily the safety and tolerability of PDR001 in combination with regorafenib.

Regorafenib is a novel oral multi-kinase inhibitor which targets angiogenic, stromal and oncogenic receptor tyrosine kinases. It is currently registered for GIST and mCRC. When regorafenib is co-administered with an acid suppressive agent, the intra-gastric pH increases, and as a result the equilibrium of ionized/non-ionized regorafenib may shift to the less soluble non-ionized form which reduces regorafenib bioavailability and exposure. Since proton pump inhibitors (PPIs) are often used during regorafenib therapy, this drug-drug interaction (DDI) confronts pharmacists and oncologists with challenges in clinical practice. In this study the investigators will therefore evaluate the impact of PPI-induced intra-gastric pH elevation on regorafenib pharmacokinetics in patients with GIST and mCRC.

Chronic rhinosinusitis (CRS) with nasal polyps is a particularly challenging form of chronic rhinosinusitis in several ways. Patients have significantly more severe symptom burden and worse quality of life than patients with chronic rhinosinusitis without nasal polyps. Many patients return to the health care providers with persistent symptoms after repeated medical and surgical treatment. Patients have usually tried several different types of treatments, ranging from less invasive procedures to extensive surgical treatment. The surgical treatment is often repeated several times. The most common surgical treatment is functional endoscopic sinus surgery, another established procedure is Vidian neurectomy. The main object of this pilot study is to investigate the safety of onabotulinumtoxin A towards the sphenopalatine ganglion (SPG) in CRS patients with nasal polyps. Efficacy data will also be collected to provide indication on whether future placebo-controlled studies should be performed. Onabotulinumtoxin A inhibits the secretion of acetylcholine, blocking the parasympathetic reflex cascade in the SPG. As a result, the investigators expect less mucosal swelling, secretion and nasal polyps. The duration of such a blockade is believed to last for 3-9 months and will not lead to damage of the nerve. This study opens up for improved treatment with less complications.

The main purpose of this study is to assess the safety and tolerability and to determine the recommended phase 2 dose of S 95005 given in combination with oxaliplatin in patients with metastatic colorectal cancer.

The purpose of this study is to assess the safety and tolerability of different dose-escalation approaches of regorafenib in mCRC patients.

The investigators do the clinical trial (patients with metastatic colorectal cancer treated with donafenib/placebo after failure of standard therapy) to assess efficacy and safety of donafenib in patients with metastatic colorectal cancer, progressing after all approved standard therapies.

This is a single center, open label dose frequency escalation study of CryoVax®. personalized anti-tumor vaccine protocol combining the cryoablation of a selected metastatic lesion with intra-lesional immunotherapy with AlloStim®. The in-situ (in the body) cancer vaccine step combines killing a single metastatic tumor lesion by use of cryoablation in order to cause the release of tumor-specific markers to the immune system and then injecting bioengineered allogeneic immune cells (AlloStim®) into the lesion as an adjuvant in order to modulate the immune response and educate the immune system to kill other tumor cells where ever they reside in the body.
