Food Allergy Institute, Latitude and Curex

Food Allergy Institute describes TIP as a personalised, data-driven programme using real foods that, in their words, "Never Begins With Direct Allergen Exposure" — it starts by escalating structurally similar non-allergenic proteins before approaching the allergen itself. Standard oral immunotherapy escalates the allergen directly from the start. FAI publishes a 2.5 to 4-year duration, ages 15 months to 50 years, and says it assesses 130+ allergens.

Carefully, and this applies to every provider including us. Food Allergy Institute publishes "99% success rate after completing TIP". The wording matters: the denominator is people who completed a programme lasting two and a half to four years, not everyone who started. Providers do not generally publish how many begin and stop. Latitude publishes 98% desensitisation for patients under four and 94% across all ages, labelled on their own site as "Internal data, 2026" — their own honest flag that this is not a peer-reviewed result. Neither figure is evidence of dishonesty. Both are figures whose denominator you should ask about.

Nothing, and we would rather say that plainly than imply otherwise. The real-world study Curex clinicians published covers 2,897 patients treated for environmental allergies — pollens, dust mite, pet dander — not food allergy. Applying it to food would misrepresent what was measured. For food allergy specifically, the evidence we rely on is the published literature on sublingual immunotherapy generally, which shows a smaller rise in reaction thresholds than oral immunotherapy achieves.

If you live within reach of a clinic, can sustain a multi-year schedule of visits, and want the largest achievable rise in reaction threshold, a clinic oral immunotherapy programme is the stronger option on the evidence, and we are not going to pretend otherwise. If no clinic is reachable, or the schedule of an OIT protocol is not compatible with your family, sublingual immunotherapy under remote supervision is a real option with a smaller effect. If there is a history of anaphylaxis or severe asthma, that assessment happens in person regardless of which route you are considering.

Food Allergy Institute publishes $979 per month, or $1,079 for ages 26 and over. Over a published 2.5 to 4-year course that is roughly $29,000 to $47,000 before travel. Latitude does not publish prices and states it accepts most insurance plans, so your cost depends on your coverage. Curex lists a food allergy plan at $149 per month. Those are not like-for-like: the clinic programmes deliver a substantially larger rise in reaction threshold, and cost per month is a poor way to compare treatments that do different amounts of work. Prices change — confirm current figures with each provider.

Not directly, because the established clinic programmes largely ran their own off-label protocols rather than the branded product. It affects the wider field: with Palforzia withdrawn from the US market on 31 July 2026, no FDA-approved food immunotherapy exists, so every programme described here — clinic and remote alike — is off-label. Off-label is no longer a distinguishing feature of one provider over another.
