Trial Summary

Do I have to stop taking my current medications for the trial?

The trial requires a washout period (time without taking certain medications) of at least 21 days after the last chemotherapy dose and 14 days after the last radiotherapy session before starting the trial. Additionally, you cannot take medications that strongly affect the enzyme CYP3A4. Other current medications are not specifically mentioned, so it's best to discuss with the trial team.

What data supports the effectiveness of the drug combination LY3214996 + Cetuximab / Abemaciclib for colorectal cancer?

Research shows that cetuximab, a component of the treatment, has been effective in improving survival and response rates in patients with metastatic colorectal cancer, especially when combined with chemotherapy. This suggests that cetuximab can be a valuable part of treatment strategies for colorectal cancer.12345

What safety information is available for the treatment LY3214996 + Cetuximab / Abemaciclib for colorectal cancer?

Cetuximab, one of the drugs in the treatment, is generally well tolerated but can cause side effects like skin issues, infusion reactions, and low magnesium levels. It's important to manage these side effects promptly to continue treatment safely.46789

What makes the drug LY3214996 + Cetuximab / Abemaciclib unique for colorectal cancer?

This treatment combines LY3214996, a novel drug, with Cetuximab and Abemaciclib, which are known for targeting specific cancer pathways. Cetuximab is a monoclonal antibody that blocks the epidermal growth factor receptor (EGFR), while Abemaciclib inhibits proteins involved in cell division, potentially offering a new approach for patients who have not responded to other treatments.1011121314

What is the purpose of this trial?

This phase Ib/II trial investigates the side effects and best dose of LY3214996 when given together with cetuximab alone or in combination with abemaciclib and to see how well they work in treating patients with colorectal cancer that cannot be removed by surgery (unresectable) and/or has spread to other places in the body (metastatic). Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. LY3214996 and abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving LY3214996 and cetuximab alone or in combination with abemaciclib may help treat patients with colorectal cancer.

Trial Overview The study tests LY3214996 with cetuximab alone or combined with abemaciclib on unresectable/metastatic colorectal cancer. It aims to find the best dose of LY3214996, see how well these treatments work together, and understand their side effects.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Arm B (ERK1/2 inhibitor LY3214996, cetuximab, abemaciclib)Experimental Treatment3 Interventions
Patients receive ERK1/2 inhibitor LY3214996 and cetuximab as in Arm A. Patients also receive abemaciclib PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Group II: Arm A (ERK1/2 inhibitor LY3214996, cetuximab)Experimental Treatment2 Interventions
Patients receive ERK1/2 inhibitor LY3214996 PO QD on days 1-28 and cetuximab IV over 1-2 hours on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Findings from Research

Cetuximab is an effective monoclonal antibody that targets the epidermal growth factor receptor, showing significant clinical efficacy in treating colorectal cancer (CRC) either alone or in combination with chemotherapy.
The combination of cetuximab with chemotherapy is well tolerated, with minimal overlapping toxicities, making it a crucial treatment option for patients with metastatic CRC who do not respond to traditional chemotherapy.
Synergy between cetuximab and chemotherapy in tumors of the gastrointestinal tract.Mahtani, RL., Macdonald, JS.[2022]
In the phase III CRYSTAL study, adding cetuximab to the FOLFIRI regimen significantly improved overall survival and progression-free survival in patients with KRAS exon 2 wild-type metastatic colorectal cancer, highlighting its efficacy in this specific patient group.
However, patients with other RAS mutations did not experience any benefit from cetuximab, indicating the importance of comprehensive RAS mutation testing to tailor treatment and maximize effectiveness.
Fluorouracil, leucovorin, and irinotecan plus cetuximab treatment and RAS mutations in colorectal cancer.Van Cutsem, E., Lenz, HJ., Köhne, CH., et al.[2022]
In a study involving 1,147 patients with metastatic colorectal cancer (mCRC), the combination of cetuximab and irinotecan achieved a 12-week progression-free survival (PFS) rate of 61% and a median overall survival of 9.2 months, confirming its efficacy in a community practice setting.
The treatment was generally well tolerated, with the most common severe side effects being diarrhea (19%) and neutropenia (10%), while the incidence of severe infusion-related reactions was notably low at 1% when patients received premedication with antihistamines and corticosteroids.
