Catalent Partners with Humanigen to Support FDA-Approved Phase 3 Lenzilumab Study for COVID-19

SOMERSET, N.J. – May 7, 2020 — Catalent, a global leader in clinical supply services, today welcomed the news by Humanigen, Inc., that it has dosed the first COVID-19 patient in its previously announced Phase 3 study for lenzilumab, the company’s proprietary Humaneered® anti-human granulocyte macrophage-colony stimulating factor (GM-CSF) monoclonal antibody.

From its Philadelphia facility, Catalent has provided clinical supply support to Humanigen and its partners to accelerate the instigation of this clinical trial.

“We are honored to have supported Humanigen on this important project and have ensured that all possible resources were allocated to allow these trials to begin as soon as possible,” said Ricci Whitlow, President Clinical Supply Services at Catalent. “Our team in Philadelphia, and across the company as a whole, feel great pride in doing whatever we can in these times of global uncertainty to help in the treatment of those suffering greatly.”

“I would like to thank the staff at Catalent for their continued work, responsiveness and partnership, which has helped ensure we were able to commence the trial as quickly as we have to evaluate the potential benefits to patients hospitalized with COVID-19 pneumonia and at high risk of progression,” commented Dr. Cameron Durrant, Chairman and Chief Executive Officer of Humanigen.

Catalent’s 200,000 square-foot Philadelphia facility provides comprehensive clinical supply services including clinical supply management, comparator sourcing, package engineering primary packaging, secondary packaging and labeling, demand led supply services, cold chain distribution, clinical storage and returns and destruction.

Humanigen, Inc. is developing its portfolio of clinical and pre-clinical therapies for the treatment of cancers and infectious diseases via its novel, cutting-edge GM-CSF neutralization and gene-knockout platforms. Humanigen believes that its GM-CSF neutralization and gene-editing platform technologies have the potential to reduce the inflammatory cascade associated with coronavirus infection as well as the serious and potentially life-threatening CAR-T therapy-related side effects while preserving and potentially improving the efficacy of the CAR-T therapy itself, thereby breaking the efficacy/toxicity linkage. The company’s immediate focus is to prevent or minimize the cytokine storm that precedes severe lung dysfunction and ARDS in serious cases of SARS-CoV-2 infection and also in combining FDA-approved and development stage CAR-T therapies with lenzilumab, the company’s proprietary Humaneered® anti-human-GM-CSF immunotherapy, which is its lead product candidate. A clinical collaboration with Kite, a Gilead Company, to evaluate the sequential use of lenzilumab with Yescarta®, axicabtagene ciloleucel, in a multicenter clinical trial in adults with relapsed or refractory large B-cell lymphoma is currently enrolling. The company is also focused on creating next-generation combinatory gene-edited CAR-T therapies using strategies to improve efficacy while employing GM-CSF gene knockout technologies to control toxicity. In addition, the company is developing its own portfolio of proprietary first-in-class EphA3-CAR-T for various solid cancers and EMR1-CAR-T for various eosinophilic disorders. The company is also exploring the effectiveness of its GM-CSF neutralization technologies (either through the use of lenzilumab as a neutralizing antibody or through GM-CSF gene knockout) in combination with other CAR-T, bispecific or natural killer (NK) T cell engaging immunotherapy treatments to break the efficacy/toxicity linkage, including to prevent and/or treat graft-versus-host disease (GvHD) in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT).
