On 19-Mar-2021, the patient experienced INAPPROPRIATE SCHEDULE OF PRODUCT ADMINISTRATION (Second dose administered on 38th day). On 23-Mar-2021, the patient experienced RESPIRATORY TRACT IRRITATION (pressure in the area of her cancer (left lung cancer)/felt was like somebody was squeezing her lungs/tightened up in the area of her cancer) (seriousness criterion intervention required), PULMONARY PAIN (painful in the area of her cancer) (seriousness criterion intervention required), DYSPNOEA (difficulty in breathing) (seriousness criterion intervention required) and DISCOMFORT (lot of discomfort). On 27-Mar-2021, the patient experienced ILLNESS (really really sick - with chemotherapy), HYPERTENSION (blood pressure was slightly elevated), MALAISE (felt unusual), PYREXIA (Temperature was 100.4F.) and FATIGUE (exhausted). On 19-Mar-2021, INAPPROPRIATE SCHEDULE OF PRODUCT ADMINISTRATION (Second dose administered on 38th day) had resolved. On 26-Mar-2021, RESPIRATORY TRACT IRRITATION (pressure in the area of her cancer (left lung cancer)/felt was like somebody was squeezing her lungs/tightened up in the area of her cancer), PULMONARY PAIN (painful in the area of her cancer), DYSPNOEA (difficulty in breathing) and DISCOMFORT (lot of discomfort) had resolved. On 31-Mar-2021, ILLNESS (really really sick - with chemotherapy), HYPERTENSION (blood pressure was slightly elevated), MALAISE (felt unusual), PYREXIA (Temperature was 100.4F.) and FATIGUE (exhausted) had resolved.
