What This Article Covers

1.Merck and Moderna's mRNA drug intismeran autogene reduced melanoma recurrence in a Phase 3 trial with 1,137 patients.

2.This is the first large-scale, randomized trial to show positive results for an mRNA-based cancer therapy.

3.The personalized vaccine targets the unique mutational signature of each patient's tumor, combined with standard drug pembrolizumab.

The Big Picture
Prelims · HighMains · Medium

For the first time, an mRNA-based personalized cancer vaccine (intismeran autogene) developed by Merck and Moderna has proven effective in reducing melanoma recurrence in a large late-stage trial with 1,137 patients. This marks a breakthrough in cancer immunotherapy, demonstrating that mRNA technology, previously successful against COVID-19, can be adapted to fight cancer.

Merck-Moderna's Personalised mRNA Cancer Vaccine Intismeran Reduces Melanoma Death Risk by 49%

A first-of-its-kind personalised mRNA cancer vaccine (intismeran), developed by Merck and Moderna, combined with Keytruda, has shown a 49% reduction in risk of death from melanoma recurrence and 59% from spread in Phase 3 trials. This marks a breakthrough for cancer vaccines but has limited impact in India due to low melanoma incidence and high cost of immunotherapy.

IARC Classifies Three WHO Essential Medicines as Group 1 Carcinogens: Hydrochlorothiazide, Voriconazole, Tacrolimus

IARC, the WHO cancer research agency, has classified three widely used drugs—hydrochlorothiazide, voriconazole, and tacrolimus—as Group 1 carcinogens. Despite this, experts stress that patients should not stop treatment as the benefits for hypertension, fungal infections, and organ transplant rejection far outweigh the cancer risk. The drugs are on the WHO Model List of Essential Medicines and are commonly prescribed in India.
