DMID 04-077 Serious Adverse Events23 Mar 2006: This 6-year-old female subject was enrolled in the study and received blinded study product on 25 Jan 2006 and on 22 Feb 2006. She experienced the SAE of "Rotavirus" on 07 Mar 2006, reported as resolved
without sequelae on 14 Mar 2006. The site reported that the subject was not receiving any concomitant medications. On 07 Mar 2006, the subject
developed diarrhea which increased in severity. On 09 Mar 2006, the subject was unable to tolerate oral fluids and was admitted to the hospital to receive IV
fluids. The mother reported that other members of the family had the same symptoms, although not as severe, and that the diagnosis of rotavirus was
made after tests performed at the hospital. This event was considered resolved without sequelae on 14 Mar 2006.

DMID 04-077 Serious Adverse Events
19 May 2006 :Additional information including a follow-up email from the site and a discharge summary was received and reviewed. On 09 Mar 2006, the
subject was admitted to the hospital with vomiting, diarrhea, listlessness, lethargy and dry mucus membranes. Upon physical examination, the subject’s bowel sounds were hypoactive and mild epigastric tenderness was noted. Her remaining physical assessment was benign. Maintenance intravenous fluids were started to treat the subject’s dehydration and famotidine was given for epigastric discomfort. On 10 Mar 2006, the subject’s blood glucose was 79
(reference range and units not provided); she was tolerating oral fluids well and she was discharged to home. Discharge medications included Tylenol, Motrin
and Pepcid.

31 Jul 2006: Additional information including a follow-up SAE report form and medical reports was received and reviewed. Medical history includes tube placement for otitis media and low birth weight. On 18 Apr 2006, the subject presented to her primary care physician with vomiting and fever for one day. Upon physical examination, it was noted that her left tympanic membrane was red and bulging. Otitis media and gastroenteritis were diagnosed and Amoxil was prescribed. On 19 Apr 2006, the subject returned for follow-up. She had experienced an intermittent fever for 24 hours that peaked at 103°, vomiting and also complained of painful abdomen and legs. She was noted to have a maculopapular rash with petechiae on the buttocks and extremities including palms and soles. Amoxil had been prescribed at the previous visit for an ear infection, but the subject had not taken it. Upon physical examination, it was noted that the subject’s left tympanic membrane was dull and red and her oropharynx area was erythematous. A urinalysis and culture was negative. Laboratory analysis revealed the following abnormal results: sodium 134 mmol/L (reference range 136-145 mmol/L), hemoglobin 13.6 gm/dL (reference range 11.0-13.0 gm/dL), and lymphocytes 10.3% (reference range 40-60%). A blood culture obtained was negative. Medical notes from the follow-up visit later that day indicate that the subject was bitten by a pet rat on her index finger. The father reported that the bite was deep enough to cause bleeding. On 20 Apr 2006, the subject was admitted to the hospital and empirically treated for rat bite fever with intravenous penicillin. Rocky Mountain spotted fever antibody serologies were sent. Her condition improved and on 23 Apr 2006, the subject was discharged from the hospital with instructions to complete a 10-day regimen of amoxicillin and to follow-up with her primary care physician. Medical notes from her follow-up visit on 24 Apr 2006 indicate that the subject was taking amoxicillin as prescribed and improving.

Blood cultures were negative, as well as the Rocky Mountain spotted fever antibody, respiratory syncytial virus direct antigen enzyme immunoassay, respiratory virus antigen and culture, and influenza direct antigen screen. On 07 Jul 2006, the subject was seen for follow-up and had no complaints. On 24 Apr 2006, this event was considered resolved without sequelae.
