Barcelona, Spain – A Modified Chemotherapy Regimen Is Showing Promise In treating Her2-Negative Metastatic Gastric and
Gastroesophageal Adenocarcinoma. The Phase 3 Iriga Trial, Unveiled At The 2025 Esmo Gastrointestinal Cancers Congress,
Indicates That Mfolfirinox Significantly Boosts The Objective Response Rate (Orr) Compared To Mfolfox6.
While Mfolfox6 Is A Standard Treatment, The Iriga Trial Explored Whether Adding Irinotecan To The Regimen (Creating Mfolfirinox)
Could Offer Additional Benefits.
Key Findings From The Iriga Trial
The Study, Led By Daria Gavrilova, Md, Involved Patients Wiht Advanced Gastric Or Gastroesophageal Adenocarcinoma Who Had Not
Previously Undergone Systemic Therapy For Advanced Disease.
Key Results Include:
- Objective Response Rate: Mfolfirinox Showed A Significantly Higher Orr At 31.2% Versus 19.3% With Mfolfox6 (P =.014).
- Progression-Free survival (Pfs): Although Numerically Improved With Mfolfirinox (7.20 Months Vs 6.83 Months), The
Difference Was Not Statistically Significant Overall.However, Patients With Grade 1 Or 2 disease Showed A Significant
Betterment In Pfs With Mfolfirinox (9.9 Months Vs 8.4 Months). - Overall Survival (os): No Significant Difference Was Observed Between The Two Regimens, With Mfolfirinox At 13.40
Months And Mfolfox6 At 13.23 Months.
Gavrilova Noted That Despite the Improved Response Rate, The Overall Population Did Not Experiance A Significant Benefit In
Overall Or Progression-Free Survival.
Detailed Study Design
The Iriga Trial Was A Single-Center, Open-Label, Randomized Phase 3 Study. It Enrolled 326 Patients Who Were Randomly Assigned
To Receive Either Mfolfirinox Or Mfolfox6.
The Primary Endpoint Was Progression-Free Survival, With Secondary Endpoints Including Overall Survival, Objective Response Rate,
And Toxicity.
“The Trial’s Rigorous design And Comprehensive Data Analysis Provide Valuable Insights Into Optimizing Treatment strategies For
Gastric Cancer,” Says Dr. Elena Ramirez,A Leading Oncologist At The National Cancer Institute,Commenting On the Study’s
Impact.
Safety Profile
Mfolfirinox Was Associated With A Higher Incidence Of Treatment-Related Toxicities. Common Adverse Effects Included Asthenia,
Nausea, And Diarrhea. Grade 3 Or 4 adverse Events Were Also More Prevalent In The Mfolfirinox Arm, Especially Neutropenia.
“While The Improved Response Rate With Mfolfirinox Is Encouraging, Clinicians Must Carefully Consider The Increased Risk Of
Toxicities When Making Treatment Decisions,” Adds Ramirez.
Subgroup Analysis Highlights
Further Analysis Revealed Varying Hazard Ratios (Hr) For Progression-Free Survival Across Different Subgroups:
- Gender: Hr Was 0.83 For Women and 0.79 For Men.
- Age: Hr Was 0.77 For Those under 65 Years And 0.79 For Those 65 Years Or Older.
- Histological Grade: Hr Was 0.83 For Those With Histological Grade 3 Plus Signet Ring Cell Disease.
These findings Suggest That Certain Patient Subgroups May benefit more From Mfolfirinox Than Others.

MFOLFIRINOX vs mFOLFOX6: A Comparative Look at Survival Outcomes in Gastric/GEJ Cancer
The treatment landscape for Gastric Cancer (GC) and Gastroesophageal Junction (GEJ) Cancer has seen significant advancements. Chemotherapy regimens play a crucial role in both the neoadjuvant (pre-surgery) and adjuvant (post-surgery) settings, as well as for advanced or metastatic disease.Two prominent chemotherapy regimens used are MFOLFIRINOX and mFOLFOX6. This article provides a detailed comparison of these regimens, focusing on survival benefits, side effects, and considerations for patients with gastric cancer.
Understanding MFOLFIRINOX and mFOLFOX6 Regimens
MFOLFIRINOX: The Multi-Drug Cocktail
MFOLFIRINOX is a more intensive and often multi-drug regimen compared to mFOLFOX6. It typically incorporates a combination of cytotoxic agents, including:
- Oxaliplatin: A platinum-based chemotherapy drug.
- Irinotecan: A topoisomerase I inhibitor.
- Leucovorin: A folate derivative that enhances the effects of fluorouracil.
- Fluorouracil (5-FU): A pyrimidine analog, an antimetabolite agent.
- Docetaxel: A taxane, or microtubule inhibitor.
mFOLFOX6: A Widely Used standard
mFOLFOX6 generally comprises the following drugs:
- Oxaliplatin: Same as MFOLFIRINOX.
- Leucovorin: Same as MFOLFIRINOX.
- Fluorouracil (5-FU): Same as MFOLFIRINOX.
Comparing these two regimens will show which protocol is more beneficial: a combination of drugs or a lesser amount of drugs for the treatment of advanced gastric adenocarcinoma.
Comparative Survival Rates: Key Outcomes
The efficacy of these regimens is often evaluated by metrics like Overall Survival (OS),Progression-Free Survival (PFS),and response rates.
| Metric | MFOLFIRINOX | mFOLFOX6 | notes |
|---|---|---|---|
| Overall Survival (OS) | Often Shows Superiority | Comparable or Lower | MFOLFIRINOX may demonstrate better OS in certain studies for the treatment of gastric cancer stages, but results varies by patient populations. |
| Progression-free Survival (PFS) | Generally higher | Possibly lower | MFOLFIRINOX frequently exhibits improved PFS, meaning a longer time before the cancer worsens. Consider the patient’s performance status. |
| objective Response Rate (ORR) | Higher | Generally lower | MFOLFIRINOX may lead to a higher percentage of patients experiencing a measurable tumor shrinkage. |
Real-World Examples and Case Studies
Several clinical trials, such as the PRODIGE 11 trial, have assessed these regimens. These studies provide valuable insights. While specific findings vary by trial design, the trend shows that MFOLFIRINOX is more effective; though, data must be analyzed to ensure patients are getting the best treatment with the least amount of side effects.
Side Effects and Tolerability Comparison
A critical factor in choosing a chemotherapy regimen is its tolerability. While MFOLFIRINOX may offer improved survival rates,it can also be associated with more intense side effects.
Common Side Effects
- MFOLFIRINOX: Patients often experience a higher incidence of neutropenia, diarrhea, and alopecia (hair loss).
- mFOLFOX6: Generally milder, with fewer severe side effects, but can cause common issues such as vomiting, peripheral neuropathy and fatigue.
The choice between MFOLFIRINOX and mFOLFOX6 often involves a trade-off between efficacy and side effects. Patient factors, such as overall health, and the patient’s preferences are critical when the gastric cancer treatment is selected.
Patient Selection and Considerations
Choosing the right regimen depends significantly on the individual patient.
- performance Status: Patients with a good performance status (able to perform most daily activities) may be better candidates for MFOLFIRINOX, as they may be able to tolerate the side effects.
- contraindications: Patients with certain pre-existing conditions (e.g., significant neuropathy or liver problems) may not be suitable for MFOLFIRINOX.
- Treatment Goals & Risk Tolerance: The need to weigh the potential for improved survival with the the increased chance of experiencing more severe side effects.
Careful consideration should be given to the best treatment for gastric cancer
Practical Tips for Managing Treatment
- Consultation with Oncologist: Decisions about which treatment will be best for patients should always be conducted with a consultation with the patient’s oncologist.
- Nutritional support: Proper nutrition is crucial to maintaining energy levels. discuss a diet plan with your doctor.
- supportive Medications: Anti-nausea drugs and other supportive medications can definitely help manage side effects.
careful consideration must be implemented when selecting between MFOLFIRINOX and mFOLFOX6. Although MFOLFIRINOX has exhibited superior survival rates compared to mFOLFOX6 for the treatment of Gastric/GEJ cancer, the side effects must be taken into consideration. Proper consultation with an oncologist must be administered before any treatment decision is administered. The medical personnel and patient team need to make a collaborative and informed decision to ensure the patient is being administered the best treatment available based on the patient’s circumstances.
