Filter by:This study makes an observation over the objective response rate of Apatinib and 5-Fu combination regimen in the three-line treatment of metastatic colorectal cancer. All the participants will randomly receive the treatment of Apatinib and 5-Fu combination regimen or 5-Fu.
Drugs used against cancer work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as CMAB009, can block tumor growth in different ways. Giving combination chemotherapy together with CMAB009 as first treatment after diagnosis of a metastatic colorectal cancer（first-line treatment）may improve the treatment efficacy. However, it is not yet known whether giving combination chemotherapy together with CMAB009 is more effective than combination chemotherapy alone. This open-label trial investigates the effectiveness of CMAB009 in combination with a standard and effective chemotherapy FOLFIRI（5-Fluorouracil /Folinic acid plus Irinotecan）for RAS/BRAF wild-type, metastatic colorectal cancer in first-line setting, compared to the same chemotherapy alone.
Immune chekpoints (ICI) are evaluated in many digestive cancers. Certain types of cancer appear to be rather refractory to ICI such as colorectal cancers (CRC). However, the MSI CRC representing approximately 15% of the CRCs exhibits a high mutational load which generates many potentially immunogenic neoantigens. In addition, strong expression of PD-L1 was found in the MSI CRCs relative to the CRC (MSS) stages. Localized MSI CRCs have a better prognosis than MSS CRCs, probably due to immunogenic neoantigens associated with a CD8 + T-specific immune response. On the oher hand, in metastatic CRC (mCRC) things are different because i) the MSI frequency is only 4 to 7% and ii) the good prognosis conferred by the MSI status is controversial. Preliminary results suggest that patients with MSI mCRC are highly sensitive to ICI even chemoresistant tumors receiving several lines of chemotherapy. Recently, another anti-PD1 alone or in combination with an anti-CTLA4 (antigen associated with cytotoxic T-lymphocyte 4) was tested in the MSI CRCs and a selection of interesting results in heavily pretreated patients with a disease control rate of 56% for monotherapy and 81% for combinated therapy. Anti-PD1s now have marketing authorization for patients with melanoma and metastatic pulmonary carcinoma , Which are known to have a high level of mutations . ICIs appear to be as promising in MSI CRCs as in other tumors and therefore face the same major challenges. Avalumab is an anti-PD-L1 antibody recently tested in several different types of tumors with promising results and is currently being studied in phase III in gastric cancer. There is no data on the effectiveness of this ICI in the MSI mCRCs. In addition, only anti-PD1 was used in the MSI-mCRC and not the anti-PD-L1, and only in chemoresistance (3rd line or more). The main objective of the SAMCO study is to test the efficacy and tolerance of avelumab in the 2nd line of treatment in patients with a MSI mCRC progression after standard 1st line chemotherapy +/- targeted therapy.
Trial Design This is an open label, single-arm, phase IB/II trial to evaluate the safety, tolerability and anti-tumor efficacy of epacadostat (INCB024360) in combination with pembrolizumab (MK-3475) plus azacitidine in patients with chemo-refractory MSS mCRC. The phase 1B portion of the study will evaluate the safety, tolerability and RP2D of epacadostat (INCB024360) in combination with pembrolizumab plus azacitidine in subjects with chemo-refractory MSS mCRC without any further standard treatment options. The phase 2 portion of the study will evaluate the efficacy and safety of epacadostat (INCB024360) in combination with pembrolizumab plus azacitidine in subjects with chemo-refractory MSS mCRC without any further standard treatment options. In both phase IB and phase 2 portions, patients will receive the combination of azacitidine, pembrolizumab and epacadostat (INCB024360) for the first 18 cycles (Cycles 1-18). Beginning with Cycle 19 through Cycle 35, patients will receive the combination of pembrolizumab and epacadostat (INCB024360).
This was a phase Ib study of PDR001 in combination with bevacizumab and mFOLFOX6 as first line therapy in patients with metastatic microsatellite stable (MSS) colorectal cancer. The study was to have assessed primarily, the safety and tolerability and then the efficacy of PDR001 in combination with bevacizumab and mFOLFOX6. Particular attention would have been paid to the level of activity of study drug combinations in CMS4 patients (retrospective analysis). The study was terminated early due to company decision.
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.
The purpose of this study is to show that the type, number and/or distribution of tumor metastases infiltrating immune cells such as cytotoxic T cells and/or the cytokine signature in the tumor metastases can be modulated by treatment with olaptesed pegol and to explore safety, tolerability and efficacy of olaptesed pegol in combination with pembrolizumab as a basis for subsequent studies in combination with immunotherapies, in particular checkpoint inhibitors.
The POLE mutations represent high somatic mutation loads in patients with colorectal cancer, especially in those with MMR proficient or MSS, therefore, tumors harbouring POLE mutations might be susceptible to immune checkpoint blockade. Based on these reasons, Investigator planned a phase II study of avelumab monotherapy in patients with previously treated, metastatic, MMR deficient (MSI-H) or POLE mutated colorectal cancer.
The CHOICE Registry will describe real-world treatment patterns and physician and patient (and caregiver)-reported outcomes associated with patients who have progressed beyond 2nd line metastatic colorectal cancer.
Anti-EGFR (Epidermal Growth Factor Receptor) therapies, namely cetuximab and panitumumab, have become standards in the management of metastatic colorectal and head and neck cancers. These therapies are used in daily practice, that requiring to manage their skin and digestive toxicities. However, anti-EGFR are also frequently responsible for hypomagnesemia often neglected and under-treated. Hypomagnesemia may manifest as asthenia, cramps, muscle weakness, mood disorders. She is often underestimated because they are difficult to identify and accountable by clinicians in the context of cancer under chemotherapy. There is currently no national or international recommendation on the management of hypomagnesaemia in oncology and medicine in general. There are, however, on the market many nutritional supplements rich in magnesium in the form of tablets or oral solution, in multiple dosages. These food supplements rich in magnesium are sold without proof of effectiveness. Moreover, the prescription of oral magnesium supplementation adds to the oncology patient an over-medicalization, which can be poorly tolerated at the digestive level, and responsible for diarrhea and a lack of compliance. The European Food Safety Authority (EFSA) recommends in its opinion on "Dietary reference values for water" to consume 2 liters for women and 2.5 liters for men every day, all sources combined (food and beverages). The drink represent 80% of the water intake, that is about 1.5 Liter per day excluding food. However, there are multiple water marketed or distributed freely, with different compositions. Thus the quantity and quality of the mineral water consumed can influence the metabolism. Rozana® mineral water, has the double advantage of being the French water the most concentrated in magnesium (160 mg / L) and of being lowly concentrated in sulphate, responsible of the laxative power of certain waters. Instead of adding magnesium supplements with a poor digestive tolerance, to patients with metastatic cancer and often with a heavy treatment , the aim of this study is to evaluate whether a change in oral hydration in quantitative and qualitative terms can decrease the rate of hypomagnesemia in patients treated with anti-EGFR.
