Summary
Most efficacy, indication, comparative trial, and safety-adverse reaction frequency claims are not supported by the provided FDA label excerpts. Safety statements about “common side effects” are not evidenced in the provided label text, which only includes mechanism (12.1) and patient counseling risk topics (17).
Category Scores
Accurate Statements
MET exon 14 skipping results in a protein with a missing regulatory domain that reduces its negative regulation leading to increased downstream MET signaling.
12.1 Mechanism of Action
Capmatinib targets MET, including the mutant variant produced by exon 14 skipping.
12.1 Mechanism of Action
Unsupported Statements
Tabrecta (capmatinib) is approved for the treatment of metastatic non-small cell lung cancer (NSCLC) with a MET exon 14 skipping mutation.
No indication/approved use language is present in the provided label excerpts.
MET exon 14 skipping is a genetic mutation that leads to activation of the MET kinase, promoting tumor growth and proliferation.
Only general mechanism is partially supported; the provided excerpt does not explicitly state “activation of the MET kinase” or “promoting tumor growth and proliferation” as written.
Clinical trials have demonstrated the efficacy of Tabrecta in treating patients with MET exon 14 skipping NSCLC.
No clinical trials/efficacy results are included in the provided excerpts.
The Phase I/II EMERALD-1 study showed that Tabrecta significantly improved progression-free survival in patients with MET exon 14 skipping NSCLC.
No EMERALD-1 outcomes or PFS statements are present in the provided excerpts.
The Phase I/II EMERALD-1 study showed that Tabrecta significantly improved overall response rate in patients with MET exon 14 skipping NSCLC.
No EMERALD-1 outcomes or ORR statements are present in the provided excerpts.
In the EMERALD-1 study, median progression-free survival (mPFS) was 24.9 months for Tabrecta in MET exon 14 skipping NSCLC.
No numerical efficacy results are present in the provided excerpts.
In the EMERALD-1 study, overall response rate (ORR) was 67% for Tabrecta in MET exon 14 skipping NSCLC.
No numerical efficacy results are present in the provided excerpts.
Comparative studies have shown that Tabrecta may be more effective than platinum-based chemotherapy in patients with MET exon 14 skipping NSCLC.
No comparative efficacy statements or chemotherapy comparison data are present in the provided excerpts.
The EMERALD-3 study showed that Tabrecta resulted in a higher overall response rate (ORR) than chemotherapy (69% vs 35%).
No EMERALD-3 outcomes or comparative ORR data are present in the provided excerpts.
The EMERALD-3 study showed that Tabrecta resulted in longer median progression-free survival (PFS) than chemotherapy (24.8 months vs 7.3 months).
No EMERALD-3 outcomes or comparative PFS data are present in the provided excerpts.
Common side effects of Tabrecta include fatigue.
The provided excerpt (17) lists risks to counsel on but does not provide “common side effects” or frequency/adverse reaction listings such as fatigue.
Common side effects of Tabrecta include nausea.
No nausea adverse reaction listing or “common” frequency support is present in the provided excerpts.
Common side effects of Tabrecta include vomiting.
No vomiting adverse reaction listing or “common” frequency support is present in the provided excerpts.
Common side effects of Tabrecta include headache.
No headache adverse reaction listing or “common” frequency support is present in the provided excerpts.
Common side effects of Tabrecta include changes in liver function tests.
The excerpt mentions need for lab tests and hepatotoxicity risk, but does not state “common side effects” or that “changes in liver function tests” are common adverse reactions.
Adverse reactions were reported in some patients treated with Tabrecta.
No adverse reaction section or statement about reporting “in some patients” is present in the provided excerpts.
The treatment was generally well-tolerated in the context described in the response.
No tolerability conclusion (e.g., “generally well-tolerated”) is present in the provided excerpts.
Tabrecta was granted a breakthrough therapy designation by the FDA for the treatment of MET exon 14 skipping NSCLC.
No FDA designation information is present in the provided excerpts.
Tabrecta was granted orphan drug designation by the FDA for the treatment of MET exon 14 skipping NSCLC.
No FDA designation information is present in the provided excerpts.

Patent/legal expiration information is not present in the provided label excerpts.
According to the cited source (DrugPatentWatch.com), the patent for Tabrecta expired in 2030 for liquid suspensions.
Patent/legal expiration information is not present in the provided label excerpts.
There are no biosimilars available for Tabrecta.
Biosimilar availability information is not present in the provided label excerpts.
There are no generics available for Tabrecta.
Generic availability information is not present in the provided label excerpts.

Regulatory/legal biosimilar/generic development statements are not present in the provided label excerpts.
Contradictions
Important Omissions
FDA-approved indication(s) and the exact patient population wording (e.g., disease stage, biomarker criteria) are not provided in the excerpt set, preventing on-label validation of the indication claim.

Primary Issue
Most high-impact claims (indication approval, efficacy/clinical trial results, common adverse reactions, FDA designations, and patent/biosimilar/generic status) are not supported by the provided FDA label excerpts.
Suggested Improvement
Limit claims to what is explicitly supported by the provided label sections (12.1 mechanism and 17 patient counseling risk topics). Provide additional label excerpts (e.g., Indications and Usage, Clinical Studies, Adverse Reactions, Dosage and Administration, Contraindications, Warnings/Boxed Warning) before asserting specific efficacy metrics, comparative trial results, or “common” side effects.
