Recombinant human tumor necrosis factor receptor Fc fusion protein (Etanercept): experience as a therapy for sight-threatening scleritis and sterile corneal ulceration

To review the efficacy of Etanercept as an alternate therapy for treatment of necrotizing anterior scleritis and sterile corneal ulceration unresponsive to traditional therapies. A retrospective review of 10 patients treated with Etanercept for vision-threatening scleritis and sterile corneal ulceration. Etanercept alone or in combination with other immunosuppressive therapies controlled inflammation, arrested tissue ulceration, and in many cases permitted tapering or cessation of toxic immunosuppressive therapies. No complications or systemic toxicity were observed with Etanercept use. Etanercept is an effective treatment for scleritis and sterile corneal ulceration and has a favorable benefit-to-risk ratio. It may be considered for therapy of progressive disease or cases that are unresponsive to traditional therapies

A Randomized Phase I Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Recombinant Erwinia Asparaginase (JZP‐458) in Healthy Adult Volunteers

L‐asparaginase has been an important component of acute lymphoblastic leukemia (ALL) therapy for over 40 years, and is standard therapy during ALL induction and consolidation treatment. L‐asparaginases are immunogenic and can induce hypersensitivity reactions; inability to receive asparaginase has been associated with poor patient outcomes. There are L‐asparaginases of varied bacterial origins, with the most commonly used being Escherichia coli (E. coli); therefore, to ensure that patients who develop hypersensitivity to E. coli‐derived asparaginases receive an adequate therapeutic course, alternative preparations are warranted. JZP‐458 is a recombinant Erwinia asparaginase produced using a novel Pseudomonas fluorescens expression platform that yields an enzyme with no immunologic cross‐reactivity to E. coli‐derived asparaginases. To evaluate the safety, tolerability, and pharmacokinetics (PK) of a single dose of JZP‐458, a randomized, single‐center, open‐label, phase I study was conducted with JZP‐458 given via i.m. injection or i.v. infusion to healthy adult volunteers. At the highest doses tested for each route of administration (i.e., 25 mg/m2 i.m. and 37.5 mg/m2 i.v.), JZP‐458 achieved serum asparaginase activity (SAA) levels ≥ 0.1 IU/mL at 72 hours postdose for 100% of volunteers. Bioavailability for i.m. JZP‐458 was estimated at 36.8% based on SAA data. All dose levels were well‐tolerated, with no unanticipated adverse events (AEs), no serious AEs, and no grade 3 or higher AEs. Based on PK and safety data, the recommended JZP‐458 starting dose for the pivotal phase II/III study in adult and pediatric patients is 25 mg/m2 i.m. and 37.5 mg/m2 i.v. on a Monday/Wednesday/Friday dosing schedule
