Primary Outcome Measures:
  • The primary endpoint is clinical response to treatment, defined as (1) tolerating ten times the initial oral food challenge threshold dose, OR (2) tolerating the maximum oral food challenge dose at the oral food challenge, at completion of immunotherapy. [ Time Frame: Approximately 1 1/2 years. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The proportion of patients who maintain a clinical response after withdrawal of treatment for one week. [ Time Frame: Approximately 1 1/2 years. ] [ Designated as safety issue: No ]
  • The proportion of patients who maintain a clinical response after withdrawal of treatment for six weeks. [ Time Frame: Approximately 1 1/2 years. ] [ Designated as safety issue: No ]
  • Incidence of all serious adverse events during the study [ Time Frame: Approximately 1 1/2 years. ] [ Designated as safety issue: Yes ]
  • Incidence of all adverse events during the study. [ Time Frame: Approximately 1 1/2 years. ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 30
Study Start Date: August 2008
Estimated Study Completion Date: June 2015
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
These subjects will start with a dose escalation of the milk protein extract given sublingually, and then will switch to milk powder given orally and will undergo a dose escalation for a goal of 2000 mg. After dose escalation, they will continue on the oral daily maintenance dose for approximately one year.
Drug: Milk Protein Extract Immunotherapy
Sublingual extract given daily in escalating doses with goal of 4 mg/day for approximately 20 weeks.
Drug: Milk Powder Immunotherapy
Milk powder given orally in escalating doses with a goal dose of 2000mg/day given for approximately 1 1/2 years.
Experimental: 2
These subjects will start with a dose escalation of the milk protein extract given sublingually, and then will switch to milk powder given orally and will undergo a dose escalation for a goal of 1000 mg. After dose escalation, they will continue on the oral daily maintenance dose for approximately one year.
Drug: Milk Protein Extract Immunotherapy
Sublingual extract given daily in escalating doses with goal of 4 mg/day for approximately 20 weeks.
Drug: Milk Powder Immunotherapy
Milk powder given orally in escalating doses with a goal of 1000mg/day for approximately 1 1/2 years.
Experimental: 3
These subjects will have a dose escalation of the milk protein extract given sublingually. After dose escalation, they will continue on the sublingual daily maintenance dose for approximately one year.
Drug: Milk Protein Extract Immunotherapy
Sublingual extract daily in escalating doses to goal of 7mg/day for approximately 1 1/2 years.
