Trial Summary
What is the purpose of this trial?To find the recommended dose of ulixertinib that can be given in combination with cetuximab and/or encorafenib to patients with unresectable/metastatic CRC and who have received EGFR or BRAF-directed therapy in the past.
Do I need to stop my current medications to join the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, there is a required 'washout period' (time without taking certain medications) of at least 21 days after your last chemotherapy dose and 7 days after radiotherapy before starting the study.
What data supports the effectiveness of the drug combination Ulixertinib + Cetuximab / Encorafenib for colorectal cancer?
Cetuximab, when used with other drugs like FOLFIRI, has been shown to improve survival and response rates in patients with certain types of metastatic colorectal cancer. This suggests that Cetuximab can be effective in treating colorectal cancer, especially when combined with other treatments.
12345What safety data exists for Ulixertinib + Cetuximab / Encorafenib in humans?
The combination of encorafenib and cetuximab has been studied in patients with metastatic colorectal cancer, showing common side effects like fatigue, nausea, diarrhea, skin rash, and decreased appetite. Cetuximab, when used with irinotecan, has shown skin toxicity, diarrhea, and fatigue as side effects, but severe side effects were rare.
25678What makes the drug combination of Ulixertinib, Cetuximab, and Encorafenib unique for colorectal cancer?
This drug combination is unique because it targets the BRAFV600E mutation in metastatic colorectal cancer, which is a specific genetic change in the cancer cells. Encorafenib and Cetuximab have shown improved survival rates compared to standard treatments, and the addition of Ulixertinib may enhance the effectiveness of this targeted therapy.

Economic Analysis of First-Line Treatment with Cetuximab or Panitumumab for RAS Wild-Type Metastatic Colorectal Cancer in England. [2021]Label="BACKGROUND">Combination therapies with cetuximab (Erbitux®; Merck Serono UK Ltd) and panitumumab (Vectibix®; Amgen UK Ltd) are shown to be less effective in adults with metastatic colorectal cancer who have mutations in exons 2, 3 and 4 of KRAS and NRAS oncogenes from the rat sarcoma (RAS) family.
Cetuximab and irinotecan as third line therapy in patients with advanced colorectal cancer after failure of irinotecan, oxaliplatin and 5-fluorouracil. [2018]Cetuximab (Erbitux) in combination with irinotecan is the most promising combination in heavily pretreated patients with advanced colorectal cancer. Efficacy of this combination was confirmed in the pivotal BOND I study. The aim of the present study was to evaluate efficacy and toxicity of a combination regimen of cetuximab and irinotecan but in contrast to the BOND I study all patients had previously received 5-FU, oxaliplatin and irinotecan and all had progressed during or shortly after completion of treatment. Before January 2005 salvage therapy with cetuximab and irinotecan was not used in Denmark. The Danish government had initiated a national programme for patients with advanced cancer and according to this programme the National Board of Health may approve and finance experimental treatment. From January 2005 to September 2005, 65 consecutive patients were treated with cetuximab (weekly) and irinotecan (each 2 or 3 weeks) at three university hospitals. Median age was 57 years (23-78), and median performance status was 1 (0-3). Response rate was 20%, median TTP was 5.5 months and median OS was 10.4 months. Response and survival was significantly correlated with severity of skin toxicity. Toxicity grade 3 was rare (skin toxicity 8%, diarrhoea 10%, nausea 3%, vomiting 3%, fatigue 8%). Salvage therapy with cetuximab and irinotecan is effective in patients pretreated with irinotecan, and oxaliplatin and in a general population the results from the BOND I study was confirmed.
Clinical use of monoclonal antibodies to the epidermal growth factor receptor in colorectal cancer. [2018]Monoclonal antibodies to the epidermal growth factor receptor (EGFR) are among the promising novel targeted therapies being explored in colorectal cancer. Two such agents that inhibit EGFR signaling by interfering with ligand-binding are cetuximab (Erbitux) and panitumumab (Vectibix). This review will address the use of cetuximab and panitumumab in chemotherapy-refractory colorectal cancer as well as in front-line therapy for the disease, consider predictors of response and resistance, and outline comparisons between these agents.
Cetuximab: a guide to its use in combination with FOLFIRI in the first-line treatment of metastatic colorectal cancer in the USA. [2021]Cetuximab (Erbitux(®)) is a monoclonal antibody that targets the epidermal growth factor receptor (EGFR). In the USA, the approval of cetuximab has been recently expanded to include the first-line treatment of patients with KRAS mutation-negative (wild-type), EGFR-expressing, metastatic colorectal cancer (mCRC) when used in combination with FOLFIRI (irinotecan, fluorouracil, leucovorin [folinic acid]). The addition of cetuximab to first-line treatment with FOLFIRI improved progression-free survival, overall survival, and objective response rates relative to treatment with FOLFIRI alone in patients with EGFR-expressing mCRC with KRAS wild-type tumors. Therefore, cetuximab plus FOLFIRI is a useful biomarker-directed option in the first-line treatment of this patient population.
A Japanese post-marketing surveillance of cetuximab (Erbitux®) in patients with metastatic colorectal cancer. [2022]Cetuximab (Erbitux(®)) was approved for the treatment of metastatic colorectal cancer in Japan in 2008. To verify information on the safety in practical use of cetuximab, we conducted post-marketing surveillance in accordance with the conditions for approval.
The EMA assessment of encorafenib in combination with cetuximab for the treatment of adult patients with metastatic colorectal carcinoma harbouring the BRAFV600E mutation who have received prior therapy. [2021]On 2 June 2020, a marketing authorisation valid through the European Union (EU) was issued for encorafenib in combination with cetuximab in adult patients with metastatic colorectal carcinoma (mCRC) with the BRAFV600E mutation who had received prior systemic therapy. Encorafenib plus cetuximab was evaluated in a randomised phase III trial of encorafenib plus binimetinib plus cetuximab versus encorafenib plus cetuximab versus cetuximab plus irinotecan or FOLFIRI (control arm) to adult patients with BRAFV600E mCRC who had received prior therapy for metastatic disease. The median overall survival was 9.3 months [95% confidence interval (CI): 8.05-11.30] versus 5.88 months (95% CI: 5.09-7.10) for encorafenib plus cetuximab (doublet) versus the control arm, respectively [hazard ratio (HR) 0.61, 95% CI: 0.48-0.77]. Progression-free survival (PFS) was 4.27 months (95% CI: 4.07-5.45) versus 1.54 months (95% CI: 1.48-1.91) (HR 0.44; 95% CI: 0.35-0.55). The most frequent adverse events in patients receiving encorafenib plus cetuximab were fatigue, nausea, diarrhoea, acneiform dermatitis, abdominal pain, arthralgia, decreased appetite, vomiting and rash. The aim of this manuscript is to summarise the scientific review of the application leading to regulatory approval in the EU.
Adverse Events Associated with Encorafenib Plus Cetuximab in Patients with BRAFV600E-mutant Metastatic Colorectal Cancer: An in-depth Analysis of the BEACON CRC Study. [2023]Label="BACKGROUND">The BRAF inhibitor encorafenib in combination with cetuximab was recently approved for patients with BRAFV600E-mutated (BRAFV600Emut) metastatic colorectal cancer (mCRC). Approval was based on positive results from the phase 3 BEACON CRC study in BRAFV600Emut mCRC patients who had progressed after 1-2 previous regimens. This analysis provides a detailed examination of the adverse events (AEs) of interest (AEIs) with encorafenib+cetuximab in the BEACON study to aid gastrointestinal oncologists, given the limited experience with this combination.
[The efficacy of cetuximab for metastatic colorectal cancer]. [2018]Cetuximab (Erbitux) is a targeted therapy that used to treat metastatic colorectal cancer. It is classified as a "monoclonal antibody" and "signal transduction inhibitor" by binding to epidermal growth factor receptors (EGFR). We report 6 patients who responded well to cetuximab out of 8 patients with recurrent/advanced colorectal cancer who have received the drug at our hospital since November 2008. Four patients were men and 2 were women, with their ages ranging from 48 to 77 years. The primary cancers were located in the rectum (n=1), sigmoid colon (n=4), and ascending colon (n=1). Performance status (PS) was 0-1. These patients were treated with cetuximab as second-line (n=1), third-line (n=3), fifth-line (n=1), or seventh-line (n=1) therapy. Three patients received cetuximab monotherapy, while the other 3 were given CPT-11 (150 mg/m2, every 2 weeks) as concomitant therapy. Among the 3 patients receiving combination therapy, 2 patients had already received treatment with FOLFIRI. Even in the cetuximab monotherapy group, a partial response (PR) was observed in 2 patients, demonstrating a strong cytoreductive effect. Tumor markers also showed large decreases, with the percent decrease at 1 month being 31.7% and 60.8% in the monotherapy and combination therapy groups, respectively, while it was respectively 14.1% and 29.5% at 2 months. The mean progression-free survival (PFS) time and the time to treatment failure (TTF) were respectively 3.0 months and 4.5 months in the monotherapy group versus 7.3 months and 9.3 months in the combination therapy group. Acneiform rash and paronychia occurred in all 6 patients.
Encorafenib: A Review in Metastatic Colorectal Cancer with a BRAF V600E Mutation. [2021]Encorafenib (Braftovi®) is an oral small molecule BRAF inhibitor used in combination with cetuximab for the treatment of adult patients with metastatic colorectal cancer (mCRC) with a BRAF V600E mutation, who have received prior systemic therapy. In a clinical trial in adults with BRAF V600E-mutated mCRC who had disease progression after one or two previous regimens (BEACON CRC), encorafenib plus cetuximab was associated with a significantly longer median overall survival (OS), a higher objective response rate (ORR) and longer median progression-free survival (PFS), compared with standard therapy. Encorafenib plus cetuximab had a manageable tolerability profile in BEACON CRC. Current evidence suggests that encorafenib plus cetuximab combination therapy is an important targeted regimen for patients with mCRC and a BRAF V600E mutation who have received prior therapy.
Antitumor Efficacy of Dual Blockade with Encorafenib + Cetuximab in Combination with Chemotherapy in Human BRAFV600E-Mutant Colorectal Cancer. [2023]Encorafenib + cetuximab (E+C) is an effective therapeutic option in chemorefractory BRAFV600E metastatic colorectal cancer (mCRC). However, there is a need to improve the efficacy of this molecular-targeted therapy and evaluate regimens suitable for untreated BRAFV600E in patients with mCRC.
Encorafenib, binimetinib, and cetuximab in BRAF V600E-mutated colorectal cancer: an early post-marketing phase vigilance study. [2023]Triplet and doublet regimens of encorafenib plus cetuximab with and without binimetinib, respectively, were approved in Japan for unresectable, metastatic, BRAF V600E-mutated colorectal cancer (mCRC) that had progressed after 1-2 prior chemotherapies. This early post-marketing phase vigilance (EPPV) study collected adverse drug reactions (ADRs) from Japanese patients to ensure safety measures as appropriate.
