Larotrectinib is approved for the treatment of patients with solid tumors harboring NTRK gene fusions who may are expected to be immunocompromised while receiving the agent. Cases of invasive disease have been caused by Penicillium species similar to Penicillium brevicompactum, and often occur particularly in immunosuppressed patients. Therefore, ingestion of Penicillium brevicompactum may lead to pneumonia or invasive fungal blood infections, which may be life threatening.
