入选标准

  • Are age 6 to 21 years
  • Provide signed informed consent (by parent or legal guardian if the subject is a minor), and informed assent if applicable
  • Have a history of symptomatic reactivity to cow's milk (i.e. Eczema, urticaria, upper or lower respiratory symptoms, GI disturbances, other rash or oral symptoms)
  • Have a positive skin prick test (defined as wheal 3 mm ≥ negative control) and cow's milk- immunoglobulin E (IgE) > 0.35 kilo Immunoglobulin Units (kIU)/L
  • Have a positive OFC to cow's milk at a cumulative dose of less than 184 milligrams of cow's milk intact protein (2,400 mg total milk protein).
  • Are using appropriate birth control if subject is female and of child bearing age.
  • Have self-injectable epinephrine (ie. EpiPen® or EpiPen Jr.®) available at home

排除标准

  • Have a history of severe anaphylaxis defined as hypoxia (cyanosis or SpO2 ≤ 92% at any stage), hypotension, confusion, collapse, loss of consciousness; or incontinence
  • Have a history of intubation related to asthma
  • Tolerate more than 184 milligrams of intact cow's milk protein at initial OFC
  • Are pregnant or lactating
  • Have a viral Upper Respiratory Infection (URI) or gastroenteritis within 7 days of OFC (OFC needs to be rescheduled)
  • Have pulmonary function tests <80% of predicted (FEV1) or clinical history consistent with more than moderate persistent asthma
  • Are currently taking greater than medium dose inhaled corticosteroid (>400 mcg/day fluticasone or fluticasone equivalent if ≤ 12 years old or > 600 mcg/day if > 12 years old)
  • Are unable to discontinue antihistamines for 5 days for long acting and 3 days for short acting prior to skin testing or food challenges
  • Have used systemic corticosteroids within 4 weeks prior to baseline visit
  • Are receiving omalizumab, beta-blocker, Angiotensin Converting Enzyome (ACE) inhibitor or tricyclic antidepressant therapy
  • Have a chronic disease (other than asthma, atopic dermatitis or rhinitis) requiring therapy (e.g., heart disease, diabetes)
  • Have participated in any interventional study for treatment of a food allergy in the past 12 months
  • Have a severe reaction at initial DBPCFC, defined as either:
  • Life-threatening anaphylaxis, or Reaction requiring hospitalization

研究组 & 干预措施

Sublingual Immunotherapy (SLIT)

Experimental

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.

干预措施: Milk Protein Extract Immunotherapy goal of 4mg/day (Drug)

Sublingual Immunotherapy (SLIT)

Experimental

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

干预措施: Milk Protein Extract Immunotherapy goal of 7mg/day (Drug)

SLIT/ Oral Immunotherpay (OIT) B

Experimental

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.
