Abstract

The American Academy of Allergy, Asthma & Immunology and the American College of Allergy, Asthma and Immunology Executive Committees formed the Omalizumab Joint Task Force with the purpose of reviewing the Genentech Xolair (omalizumab) clinical trials and postmarketing surveillance data on anaphylaxis and anaphylactoid reactions. Using the definition of anaphylaxis proposed at a 2005 multidisciplinary symposia, the Omalizumab Joint Task Force concluded that 35 patients had 41 episodes of anaphylaxis associated with Xolair (omalizumab) administration between June 1, 2003, and December 31, 2005. With 39,510 patients receiving Xolair (omalizumab) during the same period of time, this would correspond to an anaphylaxis-reporting rate of 0.09% of patients. Of those 36 events for which the time of reaction was known, 22 (61%) reactions occurred in the first 2 hours after one of the first 3 doses. Five (14%) of the events after the fourth or later doses occurred within 30 minutes. Considering the timing of these 36 events, an observation period of 2 hours for the first 3 injections and 30 minutes for subsequent injections would have captured 75% of the anaphylactic reactions. The OJTF report provides recommendations for physicians who prescribe Xolair (omalizumab) on (1) the suggested wait periods after administration and (2) patient education regarding anaphylaxis.

  • Omalizumab has been associated with anaphylactic reactions in 0.09% to 0.2% of patients, and monitoring for 30 minutes after administration is recommended.

    “Finally, omalizumab has been associated with anaphylactic reactions in 0.09% to 0.2% of patients, with current recommendations to monitor patients for 30 minutes following administration.1742,1743”

    From International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (2018) · cites this paper as [1742]

    The Incidence section reports an anaphylaxis-reporting rate of 0.09% and cites product information reporting anaphylaxis in at least 0.2% of patients. The OJTF Conclusions and Recommendations section recommends 30 minutes of observation only after the first three injections; it recommends two hours for those initial injections. The claim omits that distinction. (LLM, conf=0.93)

  • The estimated rate of systemic reaction from a pollen-food allergy is 10%, and the estimated rate of anaphylaxis is 1.7% to 10%.

    “The estimated rate of systemic reaction from a pollen-food allergy is 10% and the estimated rate of anaphylaxis is 1.7% to 10%.1742,1919,1920”

    From International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (2018) · cites this paper as [1742]

    The 'Incidence of potential Xolair (omalizumab) anaphylactic reactions' section reports a 0.09% anaphylaxis-reporting rate for patients receiving omalizumab, not rates associated with pollen-food allergy. Searches for pollen-food allergy, systemic reactions, and the claimed percentages found no passage addressing those estimates. Page numbers were not available in our copy. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
