Primary Outcome Measures:
  • Change in CM-specific Immunogloblin E (IgE) [ Time Frame: Change from baseline to after therapy (up to 18 months) ]
    Cow's milk specific IgE was measured at baseline and after therapy (kUa/L)

  • Change in CM-specific Immunoglobulin G4 (IgG4) [ Time Frame: Change from baseline to after therapy (up to 18 months) ]
    Cow's milk specific IgG4 was measured at baseline and after therapy (kUa/L)

  • Change in End Point Skin Test [ Time Frame: Change from baseline to after therapy (up to 18 months) ]
    Allergen provoked skin test (mm)

  • Oral Food Challenge Threshold (OFC) Threshold [ Time Frame: Change from baseline to after therapy (up to 18 months) ]
    mg CM protein

Arms Assigned Interventions
Experimental: Sublingual Immunotherapy (SLIT)

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.

Milk Protein Extract Immunotherapy : Sublingual extract daily in escalating doses to goal of 7mg/day for approximately 1 1/2 years.

Drug: Milk Protein Extract Immunotherapy goal of 4mg/day
Sublingual extract given daily in escalating doses with goal of 4 mg/day for approximately 20 weeks.
Drug: Milk Protein Extract Immunotherapy goal of 7mg/day
Sublingual extract daily in escalating doses to goal of 7mg/day for approximately 1 1/2 years.
Experimental: SLIT/ Oral Immunotherpay (OIT) B

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.

Milk Powder Immunotherapy : Milk powder given orally in escalating doses with a goal of 1000mg/day for approximately 1 1/2 years.

Drug: Milk Protein Extract Immunotherapy goal of 4mg/day
Sublingual extract given daily in escalating doses with goal of 4 mg/day for approximately 20 weeks.
Drug: Milk Powder Immunotherapy goal dose 1000mg/day
Milk powder given orally in escalating doses with a goal of 1000mg/day for approximately 1 1/2 years.
Experimental: SLIT/ OIT A

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.

Milk Powder Immunotherapy : Milk powder given orally in escalating doses with a goal dose of 2000mg/day given for approximately 1 1/2 years.

Milk Protein Extract Immunotherapy : Sublingual extract given daily in escalating doses with goal of 4 mg/day for approximately 20 weeks.

Drug: Milk Protein Extract Immunotherapy goal of 4mg/day
Sublingual extract given daily in escalating doses with goal of 4 mg/day for approximately 20 weeks.
Drug: Milk Powder Immunotherapy goal dose 2000 mg/day
Milk powder given orally in escalating doses with a goal dose of 2000mg/day given for approximately 1 1/2 years.
