The efficacy of evantumumab/Carestream in the treatment of EGFR mutated lung cancer

In the field of treatment of EGFR mutated non-small cell lung cancer, amivantamab (amivantamab) is considered to be one of the more breakthrough drugs in recent years. Especially for patients with EGFR exon 20 insertion mutations who have limited treatment options in the past, its clinical value has attracted much attention. From the perspective of efficacy, the advantages of evantumumab are mainly reflected in its "filling" effect and mechanism innovation.

EGFR exon 20 insertion mutations have long been regarded as "refractory mutations". Traditional EGFR-TKIs have low sensitivity to them, and patients often lack effective follow-up treatment options after chemotherapy. By blocking the EGFR and MET signaling pathways at the same time and inducing tumor cell endocytosis and degradation, evantumumab mechanically bypasses some of the resistance structure issues and regains the possibility of targeted therapy for these patients.

Evantumumab can achieve relatively stable disease control and improve symptom burden in some EGFR mutated lung cancer patients. Compared with small molecule drugs that simply inhibit EGFR, its antibody structure allows it to exert a sustained effect on the cell surface, which is one of the important reasons why its efficacy is maintained.

It is worth noting that evantumumab is not limited to exon20 insertion mutation research. Some patients who have developed resistance after receiving multiple lines of EGFR-TKI therapy may also benefit from evantumumab treatment if accompanied by abnormal activation of the MET pathway. This feature enables the overall treatment strategy for EGFR-mutated lung cancer to gradually shift from "medication for special populations" to more refined individual selection.

Of course, efficacy evaluation cannot be separated from safety and tolerability. Evantumumab is administered intravenously, and infusion-related reactions may occur in the early stages, which require standardized management. But overall, under the guidance of a doctor, the risk is controllable. Based on comprehensive drug experience, evantumumab has become one of the most realistic treatment options for patients with EGFR mutated lung cancer, especially for patients with specific drug-resistant types.
