Participant milestones

Participant milestones
Measure
Delayed Sensitivity
All subjects underwent a food challenge (week 2). Subjects undergoing delayed desensitization via milk oral immunotherapy with milk protein powder began build-up of desensitization during Week 16 and continued thru Week 50. Total active participation lasted 51 weeks.
Immediate Sensitivity
All subjects underwent a food challenge (week 2). Subjects undergoing immediate desensitization via milk oral immunotherapy with milk protein powder began build-up of desensitization during Week 3 and continued thru Week 35. Total active participation lasted 38 weeks.

PRIMARY outcome

Timeframe: 1 year

Population: The analysis population included all subjects who began desensitization per protocol.

Subjects who withdrew prior to completing the desensitization protocol and those who experienced anaphylaxis during the desensitization protocol (i.e., were unable to complete the protocol) were considered to be "treatment failures". Subjects who completed the desensitization protocol were considered to be "treatment successes".

Safety was assessed at all follow-up clinic visits. Adverse events encountered during the previous week, as documented on subjects' event journals, were reviewed. Full physical exams performed and vital signs were obtained. During desensitization, families were contacted every other day (first week) and then twice a week (weeks 2-6).
