Los Gatos, Calif., Dec. 05, 2022 (GLOBE NEWSWIRE) -- Aridis Pharmaceuticals, Inc. (NASDAQ: ARDS), a biopharmaceutical company focused on the discovery and development of novel anti-infective therapies for treating life-threatening infections, signed an exclusive term sheet to secure international development and global commercial rights upon licensure for the pan-Ebola and pan-Marburg monoclonal antibody (mAbs) programs from Mapp Biopharmaceutical, Inc. (MappBio), a privately-owned leading developer of novel pharmaceuticals for the prevention and treatment of infectious diseases with a focus on unmet needs in global health and biodefense.
- Aridis and MappBio have committed to work exclusively with each other to expeditiously complete definitive licensing agreements
- MappBio’s pan-Ebola and pan-Marburg mAb programs are currently in Phase 1 clinical studies and both products have shown best-in-class protection against live virus challenges in non-human primates
“We are very pleased to continue our history of collaborations with MappBio, particularly on the acquisition of clinical-stage assets that have supportive funding in place through licensure,” said Vu Truong, Ph.D., Chief Executive Officer of Aridis Pharmaceuticals. “This latest partnership will significantly expand our antiviral mAb portfolio with product candidates that are critical to U.S. public health preparedness and enhance the US government’s Strategic National Stockpile to protect against the next Ebola or Marburg outbreak.”
The Strategic National Stockpile is a federally funded program that acquires, stores, and distributes medical countermeasures in the event of a public health emergency.
“We are delighted at the idea of working with Aridis on these programs given their team’s strong experience with antibody development and commercialization,” commented Larry Zeitlin, Co-Founder and President of MappBio. “The current outbreak of Sudan Ebola underway in Uganda highlights the importance of advancing these programs as rapidly as possible.”
“These are important MappBio projects with strong commercial potential with both government and private market buyers globally,” added Kevin Whaley, Co-Founder and CEO of MappBio. “Vu and the Aridis team are tremendous potential commercial partners for these mAb programs, and we look forward to completing our full licensing agreement to officially move forward.”
About pan-Ebola and pan-Marburg mAb programs
The pan-Ebola program, MBP134, is a two mAb cocktail that has demonstrated effectiveness against Sudan virus (SUDV), Zaire Ebola virus (EBOV), Bundibugyo virus (BDBV), Taï Forest virus (TAFV), Reston virus (RESTV), and Bombali ebolavirus (BOMV) in laboratory studies to date, suggesting it has potential to serve as a broad-spectrum Ebolavirus countermeasure. MBP134 fully protected non-human primates from lethal Sudan Ebola virus challenge and is currently in Phase 1 studies in healthy adults. MappBio was recently awarded
MBP091 is a single human mAb that is being developed as an anti-Marburg virus therapeutic for the treatment of hemorrhagic fevers caused by Marburg virus disease and it has also been shown to be active against the closely related Ravn virus. MBP091 has been evaluated in numerous preclinical experiments and has demonstrated the ability to neutralize Marburg virus in vitro and fully protect from lethal challenge of Marburg in vivo. A Phase 1 clinical study evaluating the safety and pharmacokinetics of MBP091 in healthy adults is underway. MappBio was recently awarded
Ebola and Marburg viruses are members of the filovirus family that cause severe hemorrhagic fevers. Ebola, a deadly virus that most commonly affects people and non-human primates, is believed to be animal-borne and can spread through contact with blood, body fluids and tissues. Marburg virus was first identified in 1967 and has caused numerous outbreaks (for example, 2022 in Ghana, 2021 in Guinea, and 2017 in Uganda), with relatively high mortality rates.

Mapp Biopharmaceutical was founded in 2003 by Drs. Kevin Whaley and Larry Zeitlin to develop novel pharmaceuticals for the prevention and treatment of infectious diseases, focusing on unmet needs in global health and biodefense.
About Aridis Pharmaceuticals, Inc.
Aridis Pharmaceuticals, Inc. discovers and develops novel anti-infective therapies to treat life-threatening infections, including anti-infectives to be used as add-on treatments to standard-of-care antibiotics. The Company is utilizing its proprietary ʎPEXTM and MabIgX® technology platforms to rapidly identify rare, potent antibody-producing B-cells from patients who have successfully overcome an infection, and to rapidly manufacture monoclonal antibodies (mAbs) for therapeutic treatment of critical infections. These mAbs are already of human origin and functionally optimized for high potency by the donor’s immune system; hence, they typically do not require genetic engineering or further optimization to achieve full functionality.
The Company is advancing multiple clinical stage mAbs targeting bacteria that cause life-threatening infections such as ventilator associated pneumonia (VAP) and hospital acquired pneumonia (HAP), in addition to preclinical stage antiviral mAbs. The use of mAbs as anti-infective treatments represents an innovative therapeutic approach that harnesses the human immune system to fight infections and is designed to overcome the deficiencies associated with the current standard of care which is broad spectrum antibiotics. Such deficiencies include, but are not limited to, increasing drug resistance, short duration of efficacy, disruption of the normal flora of the human microbiome and lack of differentiation among current treatments. The mAb portfolio is complemented by a non-antibiotic novel mechanism small molecule anti-infective candidate being developed to treat lung infections in cystic fibrosis patients. The Company’s pipeline is highlighted below:
Aridis' Pipeline
AR-301 (VAP). AR-301 is a fully human IgG1 mAb targeting gram-positive Staphylococcus aureus (S. aureus) alpha-toxin and is being evaluated in a global Phase 3 superiority clinical study as an adjunctive treatment of S. aureus ventilator associated pneumonia (VAP).
AR-320 (VAP). AR-320 is a fully human IgG1 mAb targeting S. aureus alpha-toxin that is being evaluated in a Phase 3 clinical study as a preventative treatment of S. aureus colonized mechanically ventilated patients who do not yet have VAP.
AR-501 (cystic fibrosis). AR-501 is an inhaled formulation of gallium citrate with broad-spectrum anti-infective activity being developed to treat chronic lung infections in cystic fibrosis (CF) patients. This program is currently in Phase 2a clinical development in CF patients.
AR-701 (COVID-19). AR-701 is a cocktail of fully human mAbs discovered from convalescent COVID-19 patients that are directed at multiple protein epitopes on the SARS-CoV-2 virus. It is formulated for delivery via intramuscular injection or inhalation using a nebulizer.
AR-401 (blood stream infections). AR-401 is a fully human mAb preclinical program aimed at treating infections caused by gram-negative Acinetobacter baumannii.
AR-101 (HAP). AR-101 is a fully human immunoglobulin M, or IgM, mAb in Phase 2 clinical development targeting Pseudomonas aeruginosa (P. aeruginosa) liposaccharides serotype O11, which accounts for approximately
AR-201 (RSV infection). AR-201 is a fully human IgG1 mAb out-licensed preclinical program aimed at neutralizing diverse clinical isolates of respiratory syncytial virus (RSV).
