Capmatinib is a small molecule kinase inhibitor targeted against c-Met (a.k.a. hepatocyte growth factor receptor [HGFR]), a receptor tyrosine kinase that, in healthy humans, activates signaling cascades involved in organ regeneration and tissue repair. Aberrant c-Met activation – via mutations, amplification, and/or overexpression – is known to occur in many types of cancer, and leads to overactivation of multiple downstream signaling pathways such as STAT3, PI3K/ATK, and RAS/MAPK. Mutations in MET have been detected in non-small cell lung cancer (NSCLC), and the prevalence of MET amplification in epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)-naive patients with NSCLC has been reported to be 1.4% – 21%. This co-occurrence has made c-Met a desirable target in the treatment of NSCLC. Manufactured by Novartis and marketed under the brand name Tabrecta, capmatinib was granted accelerated approval by the FDA on May 6, 2020, for the treatment of NSCLC in patients whose tumors have a mutation that leads to mesenchymal-epithelial transition (MET) exon 14 skipping. The presence of the mutation must be confirmed by an FDA-approved test, such as the FoundationOne CDx assay (manufactured by Foundation Medicine, Inc.), which was approved by the FDA on the same day. As this indication was granted under an accelerated approval, its continued approval is contingent upon verification of capmatinib’s benefit in confirmatory trials. Capmatinib was approved by Health Canada on June 8, 2022.

Regulatory Framework
Assessment Methodology
Masuu Global follows a science-based, tiered and risk-based ERA methodology, aligned with applicable international regulatory requirements. For human medicinal products, our approach is primarily guided by the EMA Guideline EMEA/CHMP/SWP/4447/00 Rev. 1, effective 1 September 2024, together with relevant OECD Test Guidelines and regional regulatory requirements.
EMA — Environmental Risk Assessment
Assessment of potential environmental exposure associated with the use, manufacture and disposal of medicinal products, with a structured approach to determine whether further environmental assessment is required.
Phase I — Environmental Exposure Assessment
Initial screening to determine potential environmental exposure, covering PEC calculation, physicochemical properties, usage and dosage data, environmental entry pathways, and persistence and fate considerations.
Phase II — Environmental Fate & Effects Assessment
Where Phase I indicates further assessment is required, Phase II provides detailed evaluation of environmental fate, persistence and ecological effects — including biodegradation, bioaccumulation, aquatic toxicity, PNEC derivation and PEC/PNEC risk characterisation.
OECD & International Testing Principles
Where laboratory studies are required, testing strategies are designed with consideration of relevant OECD Test Guidelines, GLP expectations and applicable regulatory requirements.
Risk-Based Environmental Assessment
Integration of physicochemical data, environmental fate information, ecotoxicological data, existing literature, published studies, regulatory databases, usage data, and environmental monitoring data.
Weight-of-Evidence (WoE) Approach
A scientifically justified WoE approach integrates existing data and avoids unnecessary testing wherever scientifically and regulatorily justified.
ERA Assessment Pathway
Phase I → Phase II → Risk Characterization
Each phase builds on the prior tier — screening first, escalating only when the evidence demands it.
Environmental Exposure Assessment
Initial screening to determine whether the substance requires progression to Phase II.
- Product and substance information review
- Indication, dose and usage assessment
- PEC calculation and environmental exposure estimation
- Physicochemical property review
- Initial environmental risk screening
- Determination of Phase II requirement
Environmental Fate & Effects
Detailed evaluation when Phase I triggers further assessment.
- Biodegradation, hydrolysis & photolysis
- Adsorption/desorption behaviour
- Bioaccumulation potential
- Algal, Daphnia and fish toxicity
- Chronic ecotoxicity, where required
- PEC/PNEC risk characterisation
Laboratory Coordination & Study Execution
When regulatory testing is mandatory, Masuu coordinates with qualified GLP/appropriate testing laboratories and specialized scientific partners — giving clients a single point of contact across the full testing lifecycle.
