Panitumumab Skin Toxicity Prevention Trial

Background and rationale: EGFR represents the main and more studied signal activation pathway in the development of colorectal carcinoma. KRAS, NRAS, BRAF and PI3KA mutations and ERBB2 and MET amplification are responsible for most of the cases of primary resistance to anti-EGFR antibody treatments. Despite the identification of these resistance mechanisms, a primary resistance to the therapy was detected in a certain percentage of cases, in which tumour bio-molecular characteristics would suggest a possible response to anti-EGFR antibody treatment. In these cases, pathway activation mechanisms should exist, which act in an alternative, complementary or parallel way than the EGFR one, allowing tumour progression despite of EGFR pharmacological deactivation. Skin toxicity is a characteristic of drugs having EGFR as a target and it shows itself mainly as a sterile acneiform folliculitis together with neutrophils perifollicular infiltrates but also as skin xerosis and paronychia starting from the earliest cycles of treatment. This skin toxicity seems to be closely related to EGFR activation of pro-inflammatory cytokines able to activate specific inflammatory activators, which induce neutrophils granulocytes chemotaxis. Lycopene is a compound belonging to carotenoid group, largely contained in tomatoes and their derivatives, which has an extreme antioxidant activity. In Dermatology, prolonged use of ?-carotenoids in general and of lycopene in particular in the diet showed to be effective in skin protection from ageing, sunlight and radiotherapy damages because these compounds may accumulate in skin and thus contribute to reduce free radicals and inflammation effects. Moreover, lycopene ability to induce apoptosis and to inhibit cell cycle progression in some types of tumour cells, both in vitro and in vivo, has already been described. Lycopene seems to be able to suppress significantly PCNA (Proliferating cell nuclear antigen, cofactor of DNA polymerase-?) and ?-catenin nuclear expression in neoplastic cells, essential substrate of WNT/?-catenin pathway, which is itself closely connected to activating pathways often involved in carcinogenesis of some kinds of tumours, in particular of colorectal carcinoma, like Akt/GSK3?/?-catenin and Hippo pathways. For its proved skin anti-inflammatory activity as powerful free radicals scavenger, lycopene, which accumulates itself specifically in skin, could be effective in reducing anti-EGFR drugs toxicity. Contemporary use of lycopene could have a positive effect on anti-EGFR drugs treatment effectiveness in patients with metastatic colorectal carcinoma due to its ability to interfere with pathways involved in neoplastic cells proliferation. Estimated population:100 patients (50 for each of the two groups of treatment) Study Framework: In this study, patients suffering from metastatic colorectal cancer and submitted to therapy with panitumumab would be enrolled. According to indications, panitumumab would be used: in first line combined with Folfox or Folfiri; in second line combined with Folfiri or treatments containing Irinotecan in monotherapy in any therapeutic line in patients resistant to Fluoropyrimidines, Oxaliplatin and Irinotecan or intolerant to these drugs. Standard schedules of these treatments would be used. This is a phase-II, randomized, double-blind study between experimental prophylactic treatment with Lycopene vs placebo: Treatment A - lycopene tablets 20 mg Treatment B - placebo tablets Patients should take orally Lycopene/placebo after dinner (to promote its absorption), starting the day before the beginning of treatment with panitumumab for the entire duration of the therapy, until progression of the disease or definitive drug suspension for toxicity. Objectives of the study Primary objective: to assess the effectiveness of lycopene versus placebo in reducing skin toxicity induced by panitumumab in patients treated for metastatic colorectal carcinoma. Secondary objective: to assess lycopene pharmacokinetics Exploratory objectives: to assess lycopene effectiveness versus placebo in increasing panitumumab effectiveness in terms of Disease Control (DC), Objective Response (OR) and Stabilisation of the Disease (SD). To assess lycopene effectiveness versus placebo in increasing panitumumab effectiveness in terms of Progression Free Survival (PFS). As far as randomization is concerned, the two groups will be balanced according to sex, therapeutic line and institution in which patients will be treated.

Living Donor Liver Transplantation With Two Stage Hepatectomy for Patients With Isolated, Irresectable Colorectal Liver Metastases

Nearly one third of patients with colorectal cancer develop liver metastases. It is well known that the achievement of a R0-situation is one of the most important factors for a positive long-term outcome. Despite further advantages in multimodal treatment concepts, only 20 - 30 % of the patients with metastases can be resected in curative intention. Recent studies, especially from Norway, have shown that liver transplantation might be a feasible option in well selected patients since the complete hepatectomy with subsequent liver transplantation can be an option for the achievement of a R0 situation. In this study, we pursue the strategy of two-stage hepatectomy combined with a left-lateral living donor liver transplantation. Inclusion criteria are as follows: non-resectable liver metastases of a primary colorectal carcinoma with an assumed portal-venous drainage of the tumor and at least a "stable disease" after a period of eight weeks systemic chemotherapy. Patients are excluded from the study if there is an extrahepatic tumor burden (with the exception of resectable lung metastases) or if the patient is not suitable for liver transplantation due to co-morbidities. The transplantation itself will be undertaken as a living donor liver transplantation where the left lateral liver lobe (liver segments 2 & 3) from a healthy volunteer donor will serve as graft. Prior transplantation, a left hemihepatectomy in the recipient is performed and the left lateral graft will be transplanted in this position. At the end of the transplantation procedure, the right portal vein will be closed to induce a rapid growth of the graft. The second step, and therefore the completion of the operation is performed after a growth period of the transplanted left-lateral lobe: in this procedure, the right hemi-liver of the recipient will be removed and the patient is supposed to be free of tumor at this point in time.

Development of an IDEAL Framework to Standardise Cytoreductive Surgery for Colorectal Peritoneal Metastases

Cytoreduction surgery (CRS) followed by hyperthermic intra-operative peritoneal chemotherapy (HIPEC) is a relatively new treatment for selected patients with peritoneal metastases of colorectal origin (PMCR). Data from outside of trials suggest that CRS and HIPEC improves survival compared with the current standard care (chemotherapy). The big challenge is to do trials in this setting - as the intervention is complex, and there are wide variations in the process and recording of outcomes. If trials can confirm the findings from non-randomised studies there are an estimated 1000 to 2000 patients who may benefit from this intervention in the UK each year. The aim of this study is to develop a framework which can be used to undertake a randomised trial in patients with PMCR suitable for CRS with or without HIPEC. The investigators will address this using the principles of the IDEAL (Idea, Development, Evaluation, Assessment & Long term study) framework. Here, a pre-trial feasibility study will be performed between the two national peritoneal tumour treatment centres (Manchester and Basingstoke). This study is designed as such that it will take place over the following four stages: Stage 1. Comparing the treatment data from 100 operations from each of the two centres to identify which of the key components of the intervention differ as well as testing for differences in overall survival and recurrence free survival. Stage 2. Identifying sources of these differences by selecting up to 25 patients and investigating the variation in the way surgeons score key aspects of the procedure Stage 3. Development of a 'trial manual' with standardised definitions (to minimise any differences) Stage 4. Test how well people follow the manual in practice. After this study is complete, it will be possible to use the resulting trial manual to design future randomised trials to test the most suitable clinical question.

LY3200882 and Capecitabine in Advanced Resistant TGF-beta Activated Colorectal Cancer (EORTC1615)

Part I of this study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of LY3200882/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 LY3200882 plus capecitabine combination in patients with chemo-resistant CRC. The combination of LY3200882 plus capecitabine will be given as second line therapy in the phase II part of this study. Patients with chemotherapy resistant activated TGF-? 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 LY3200882 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.
