Item 8.01 Other Events.
At the 2023 American Academy of Dermatology Annual Meeting held March 17-21, it was inaccurately reported in a session on the treatment landscape in prurigo nodularis (PN) that Celldex Therapeutics, Inc.’s (“Celldex”) Phase 1b study and clinical development of barzolvolimab in PN was terminated because of the occurrence of a serious adverse event. While a serious anaphylactic adverse event was reported in a complicated patient with multiple comorbidities, the event was reviewed by the independent Data Review Committee (DRC) and following its evaluation the DRC unanimously recommended that the study and the program should proceed. Enrollment to this study was not terminated early because of the safety event and Celldex plans to continue to develop barzolvolimab for PN.
As previously disclosed, the Phase 1b study in PN was challenging to enroll in the dermatology setting, primarily because of the intravenous route of administration. Since the initiation of the PN study in late 2021, we successfully advanced the subcutaneous formulation of barzolvolimab in our ongoing Phase 2 studies in chronic urticarias. As we recently disclosed in our 2022 Annual Report on Form 10K, given the enrollment challenges and the availability of the subcutaneous formulation, we made the decision to close enrollment at 24 patients in the PN study and believe we will have sufficient data for analysis to inform future development decisions. The study remains blinded. We plan to present data from the ongoing study, including 24 weeks of follow-up, in the fourth quarter at a medical meeting and are planning for the initiation of a Phase 2 subcutaneous study in PN in late 2023 or early 2024.
As is customary in drug development, we do not typically report safety or efficacy data, including adverse event reports, in real time and rather present full or partial study data at peer reviewed medical meetings or in corporate disclosures. As we have previously stated, if we see individual safety events that we believe would meaningfully impact or meaningfully change the barzolvolimab development program then we would disclose such events in the most appropriate manner. No such events have been reported in the program.
