Humanigen and EVERSANA Announce Partnership to Support the Launch and Commercialization of Lenzilumab for the Treatment of COVID-19

Burlingame, CA, and Chicago, IL – January 10, 2021 – Humanigen, Inc. (HGEN) (Humanigen), a clinical-stage biopharmaceutical company focused on preventing and treating an immune hyper-response called cytokine storm with its lead drug candidate lenzilumab™, and EVERSANA, a pioneer of next-generation services to the global life sciences industry, today announced that they are partnering to make lenzilumab available to hospitalized and hypoxic COVID-19 patients in the event that an Emergency Use Authorization is issued from the U.S. Food and Drug Administration (FDA) and subsequent BLA.

Humanigen’s investigational treatment, lenzilumab, a proprietary Humaneered® anti-human granulocyte macrophage-colony stimulating factor (GM-CSF) monoclonal antibody, is designed to prevent and treat cytokine storm, a complication considered to be a leading cause of COVID-19 death. Data showed that up to 89 percent* of hospitalized patients with COVID-19 are hypoxic and at risk of this immune hyper-response, which can trigger acute respiratory distress syndrome in severe cases of COVID-19.

Under the terms of the agreement, and in anticipation of an EUA for the use of lenzilumab in hospitalized COVID-19 patients, Humanigen has immediate access to EVERSANA’s fully integrated services including, but not limited to, marketing, market access, medical education, health economics and outcomes research, medical information, compliance and medical science liaison teams, with each service optimized by data and predictive analytics. The agreement with EVERSANA builds on the commercial preparation and lenzilumab launch planning Humanigen has been conducting over the last several months.

“EVERSANA shares our tireless commitment to patients,” said Cameron Durrant, MD, MBA, chief executive officer of Humanigen. “We’ve matched our dedication to research and development in COVID-19 with a proven commercialization partner to ensure lenzilumab will reach patients quickly and efficiently following a potential EUA.”

“We stand ready to immediately activate our services spanning all disciplines of the product journey to ensure lenzilumab delivers significant patient value,” said Jim Lang, chief executive officer of EVERSANA. “While EVERSANA’s model can be applied to any therapy or indication, we have a moral obligation to help COVID-19 patients in distress, knowing that even with the promise of vaccines there will be many patients who contract this virus and desperately need a treatment if hospitalized and hypoxic.”

About Humanigen, Inc.

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. We believe that our GM-CSF neutralization and gene-editing platform technologies have the potential to reduce the inflammatory cascade associated with coronavirus infection. The company’s immediate focus is to prevent or minimize the cytokine release syndrome that precedes severe lung dysfunction and ARDS in serious cases of SARS-CoV-2 infection. 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). Additionally, Humanigen and Kite, a Gilead Company, are evaluating lenzilumab in combination with Yescarta® (axicabtagene ciloleucel) in patients with relapsed or refractory large B-cell lymphoma in a clinical collaboration.
