On an unknown date in Aug 2021, the patient was hospitalized with severe mental status changes and agitation, thought as been behavioral seizures, a third seizure medication was added and had been monitored by neurology. On an unknown date, MRI of the brain showed tissue malacia (encephalomalacia) but no active tumor, additionally UTI (urinary tract infection) was treated and hematochezia resulting in colonoscopy and diagnosis of colitis. On an unknown date in Dec 2021, the patient was just feeling like she was a burden on everybody, was taken to ER the other night and they said she was having panic attacks (panic attack). On 09 Dec 2021, the patient was chronically ill-appearing (illness), had inappropriate mood and affect (inappropriate affect) and PHQ-2 score was 0. Seizure was controlled on current therapy. As on 03 Feb 2022, there were no seizures and patient was still on Keppra with normal blood level. On 13 Jan 2022, MRI was stable. On an unknown date, the patient was seen in ER due to seizure activity. On an unknown date, the patient had increasing diarrhea, had seen some bright blood in the stool and experienced left arm neuropathy (neuropathy peripheral). On an unknown date in Feb 2022, CT scan of the brain and cervical spine was performed with no active disease but malacia (myelomalacia). On 28 Feb 2022, the patient was started on Gabapentin 1 capsule (100 mg) tid oral for neuropathy peripheral. On 13 Apr 2022, pain score was 10/10 (pain). On an unknown date, the patient experienced forgetfulness (memory impairment) due to which the patient missed one dose (product dose omission issue) of Cabometyx. Further the physician reported that the event memory impairment was not due to Cabometyx. The patient was on seizure control medication (unspecified).  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: As there is limited information in the case provided, the causal association between the reported events with the suspect drug BNT162B2 cannot be excluded. The case will be reassessed once new information is available.
