BURLINGAME, Calif.–(BUSINESS WIRE)–Humanigen, Inc., (HGEN) (“Humanigen”), a clinical stage biopharmaceutical company focused on preventing and treating cytokine storm with lenzilumab, the company’s proprietary Humaneered® anti-human granulocyte macrophage-colony stimulating factor (GM-CSF) monoclonal antibody, announced data on the first clinical use of lenzilumab in 12 COVID-19 patients. The manuscript, titled ‘First Clinical Use of Lenzilumab to Neutralize GM-CSF in Patients with Severe and Critical COVID-19 Pneumonia’ was published online at medRxiv.org (www.medrxiv.org/content/10.1101/2020.06.08.20125369v1). Patients showed rapid clinical improvement with a median time to recovery of five days, median time to discharge of five days and 100% survival to the data cut-off date. Patients also demonstrated rapid improvement in oxygenation, temperature, inflammatory cytokines and key hematological parameters consistent with improved clinical outcomes.
Dr. Zelalem Temesgen, Professor of Medicine at Mayo Clinic and one of the key authors of the study, said, “Lenzilumab use was associated with improved clinical outcomes and oxygen requirement, with no reported mortality. We did not observe any treatment-emergent adverse events attributable to lenzilumab and it was well-tolerated. Based on the pathophysiology of cytokine storm following SARS-CoV-2 infection, along with work conducted at Mayo Clinic on GM-CSF depletion in CAR-T therapy, lenzilumab may offer a rational approach to ameliorate the consequences of cytokine storm in COVID-19.”
Dr. Cameron Durrant, chief executive officer of Humanigen, stated, “It is extremely encouraging to see this initial group of high-risk patients with severe and critical COVID-19 pneumonia show clinical improvement on lenzilumab, and at the data cut-off point, 11 of them discharged from the hospital. All 12 patients had at least one risk factor associated with poor outcomes, such as age, smoking history, cardiovascular disease, diabetes, chronic kidney disease, chronic lung disease, high BMI, and elevated inflammatory markers, with several patients having multiple such risk factors.”
All patients were hospitalized in the Mayo Clinic system and had severe or critical pneumonia as a result of COVID-19. They were also viewed as being at high risk of further disease progression. All patients required oxygen supplementation and had elevation in at least one inflammatory biomarker prior to receiving lenzilumab. All patients had at least one co-morbidity associated with poor outcomes in COVID-19 and several patients had multiple co-morbidities: 58% had diabetes mellitus, 58% had hypertension, 58% had underlying lung diseases, 50% were obese (defined as a BMI greater than 30), 17% had chronic kidney disease and 17% had coronary artery disease. The median age was 65 years.

About COVID-19
COVID-19 is an infectious disease caused by SARS-CoV-2. COVID-19 has become a global pandemic, with almost 8 million confirmed cases and almost 450,000 deaths reported to date. Patients with severe cases of COVID-19 experience severe viral pneumonia that can progress to acute respiratory distress syndrome (ARDS), respiratory failure and death.
In severe and critical patients with COVID-19, published research suggests GM-CSF as the key link between pathogenic Th1 cells and inflammatory monocytes, which secrete additional GM-CSF1. Lenzilumab is a late clinical-stage, monoclonal antibody targeting GM-CSF, a pro-inflammatory cytokine up-regulated in the serum of COVID-19 patients2. The percentages of certain GM-CSF-expressing cells are significantly higher in the blood of ICU-admitted COVID-19 patients compared with healthy controls and are more pronounced in ICU-admitted COVID-19 patients versus non-ICU patients2.

About Humanigen, Inc.
Humanigen, Inc. is developing its portfolio of clinical and pre-clinical therapies for the treatment of inflammation and cancers 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 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 potential registrational Phase III study in COVID-19 patients is currently enrolling. 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).

Thank God Trump lost. Treatments for COVID can now have favorable press!
RE: Thank God Trump lost.
Has he?
Note publication date of 6-15-2020. Old news.

Has any other later study superceded and falsified this one from Mayo Clinic? If not, then the study remains valid. And it isn’t even that old -— just 6 months ago.

Whatever it does have know this: it is identical!!!
Hmmm?
Aviptidal aka rlf-100... Is the cure.
Hard though I try, I cannot avoid finding the fault of “political correctness” has destroyed our scientists’ ability to do ... anything.
“How many angels can dance on a pin?”
Was a great concern of medieval ‘scientists’.
Just as “climate warming” today, it determined one’s advancement.
