The safety and clinical efficacy of a liquid, β-propiolactone-stabilized intravenous γ-globulin, Intraglobin-F, was evaluated in a multicenter, double-blind study comparing Intraglobin-F to Gamimune-N, Sandoglobulin, or Gammagard. β-Propiolactone stabilizes the IgG molecule to decrease aggregate formation and is a potent virucidal agent that reduces the risk of viral transmission by intravenous γ-globulin (IVIG) preparations. Twenty-seven patients with primary immunodeficiency diseases were enrolled at three centers. Each patient received 6 months of therapy with either Intraglobin-F or the IVIG preparation that they had received during the preceding 3 months, then crossed over to the other preparation. Twenty-three patients completed the study. One patient withdrew because of an adverse event, generalized urticaria. A second patient withdrew because of fatigue and perceived decreased efficacy. Adverse reactions were comparable and occurred in 8.7% of the infusions of Intraglobin-F and 6% of the infusions with Sandoglobulin. None were severe or life-threatening. There was no discernible difference in efficacy between any of the products. The number of days when patients noted symptoms in their diaries was similar for Intraglobin-F and the comparison preparations, 4158 vs 4143. Similarly, there were no differences in the number of physician visits (33 vs 22), days missed from work or school (405 vs 404), days with fever (41 vs 47), or days of prophylactic antibiotics (675 vs 642). There was an increase in the number of days when antibiotics were given therapeutically (578 vs 451); most of the difference was attributable to one patient. There also was a difference in the number of days of hospitalization (21 vs 0), but 19 of the days were accounted for by two patients. When the patients were asked to score their feeling of well-being on a scale of 1 to 5, with 1 being entirely well, the mean score for the patients on Intraglobin-F was 1.86 (range, 1.0 to 3.0), compared to 1.85 (range, 1.0 to 3.2) for patients while on the comparison preparations. Trough IgG levels were slightly lower during the period when patients were treated with Intraglobin-F compared to the other products. There were no abnormalities in blood chemistries or hematologic parameters. Thus, Intraglobin-F is comparable to three of the marketed IVIG preparations in efficacy and safety, as well as patient acceptability, and offers the additional benefit of an extra virucidal step to reduce further the risk of transmitting viral infections.
