Mechanism of Action Using a Dual Targeted Approach

A class of proteins called moonlighting proteins contribute to Candida virulence and pathogenicity through their involvement in mechanisms critical for successful host colonization and infection, such as the adhesion to host cells, interactions with plasma homeostatic proteolytic cascades, responses to stress conditions and molecular mimicry.1 These proteins normally are present within the fungal cell where they are involved with metabolism, however, by unknown mechanisms, they are secreted and associated with the cell wall of the fungal cell where they “moonlight” as virulence factors. The documented knowledge of the roles of these proteins in C. albicans pathogenicity has utility for assisting the design of new therapeutic, diagnostic and preventive strategies against candidiasis.

  • Our research demonstrates that antibodies to two of these proteins Met6 (5-methyltetrahydropteroyltriglutamate-homocysteine S-methyltransferase) and Fba (fructose-1,6-bisphosphate aldolase) specifically bind to peptide epitopes in the full-length Candida proteins and prevent virulence. Both antibodies protect neutropenic A/J mice from lethal challenge with C. albicans. A cocktail containing both anti-Met6 and Fba antibodies protect neutropenic A/J mice from lethal challenge with C. albicans and C. auris. We are currently investigating the development using a bispecific antibody using these antibodies.
  • Our initial studies are focused on the treatment of Candida, with expanded indications for the treatment of aspergillus.
Fba Venn Diagram
Our fully human antibodies are designed to bind to both Fba and Met6. Our strategy is to develop a bispecific antibody to inhibit these targets.

Adipose-derived Mesenchymal Stem Cell Protein Delivery Technology

Adipose-derived stem cells (ADMSCs) provides a promising future in the field of tissue engineering and regenerative medicine. Our patented ADMSC platform has the potential to be used with a number of therapeutic indications where chronic or longer-term administration of antibodies and improved compliance is warranted. This is a new paradigm for the delivery of antibody therapeutics.

Mesenchymal stem cells (MSCs) have the ability to self-renew and to differentiate into one or more specialized cell types. It is, however, the ability of MSCs to maintain and express very large human genomic DNA fragments (>300 kb) as non-integrating episomes that provides a significant advantage over viral vectors and other gene delivery approaches.

We have demonstrated that human ADMSCs transfected with episomal vectors that express human monoclonal antibodies to Candida sp. virulence factors produce functional antibodies in vitro and in mice. The company is currently optimizing cell preparation and delivery methods and optimizing expression vectors.

Discovery Research

Stadius has access to patient derived peripheral blood monocytes (PBMCs) from various and unique populations using proprietary approaches. From these, we have been able to isolate neutralizing anti-viral antibodies. These viruses cause significant disease burden in immunocompromised patients, trauma patients, and in certain patients suffering from hematopoietic cancers and carcinomas.

Invasive Fungal Infections (IFI) Market

The most common invasive fungal infections are due to invasive candida spp (IC) and invasive aspergillus spp (IA) and are becoming more prevalent as the use of immunosuppressive therapies for the management of malignancy, transplantation, and rheumatology increases.  Improved longevity and the survival of patients with multiple comorbidities and advanced disease is also contributing to increased rates of fungal infection. The presence of multiple risk factors and severe illness makes patients admitted to the ICU particularly vulnerable to these infections.  It is estimated that approximately 1.5M patients admitted to the ICU per year are vulnerable to IFIs.

Mortality rates associated with IC alone have been reported to be about 40% to 60% in ICU patients and 80% to 90% in patients with septic shock. These infections also place a significant financial burden on the health care system because of longer hospital stays, use of expensive therapies, and increased consumption of health care resources.

The most common fungal infections in patients with COVID-19 include aspergillosis or invasive candidiasis, including C.auris, an emerging pathogen. It is estimated that 25% of severe Covid-19 patients have contracted invasive fungal infections, particularly after being treated with immune suppressing drugs, such as dexamethasone or IL-6 inhibitors.2

There have been very few significant treatment developments to fungal infections, and current medications may result in toxicity or drug interactions, and may require renal adjustment with increasing rates of resistance resulting in potentially costly and life-threatening outcomes.

The current U.S. market is estimated to be approximately $3.5B in 2027 with global forecasts reaching approximately $8.2B at a CAGR of 4.5% representing current agents, the majority of which are generic. All recently approved drugs as well as those in development are small molecule agents, many of which are being developed only in oral formulation.

Our differentiated antibody therapeutics are designed to inhibit colonization and invasion using a dual targeted and novel mechanistic approach. With the advent of COVID-19, antibodies are becoming more accepted and acknowledged as a means of treatment for viral infections and other pathogens. Primary market research has indicated a keen interest by physicians for alternatives to current anti-fungal agents. Historically, fully human antibodies have had an excellent safety and distribution profile and are well tolerated, with a very low incidence of allergic reactions.

Worldwide forecast estimate for Invasive Fungal Infections due to Candida and Aspergillosis, 2021.

Invasive Candidiasis

The world-wide incidence of IC or candidemia is estimated at 400,000 patients per year. It is the most frequent hospital infection and accounts for up to 15% of bloodstream infections and is the main causative agents in 50-70% of systemic fungal infections. IC presents with high morbidity and mortality in immunosuppressed or immunocompromised populations who have chronic diseases as well as in transplant recipients. Mortality ranges in these patients from 40-70%. Many of these patients are taking drugs to prevent transplant rejection as well as corticosteroids that are immunosuppressive. Other contributors include the overuse of antibiotics in post-surgical patients and trauma patients in the ICU and certain medical and intubation devices where colonization is frequent. It is estimated that 50% of post-surgical procedures in the ICU will get candida peritonitis per year.3

Candida auris: An Emerging Healthcare Threat

Candida auris is an emerging fungus that presents a serious global health threat. It can cause invasive infections associated with up to 40% in-hospital mortality. Most strains of C. auris are resistant to at least one antifungal drug, one-third are resistant to two antifungal drug classes, and some strains are resistant to all three major classes of antifungal drugs. C. auris can spread readily between patients in healthcare facilities. It has caused numerous healthcare-associated outbreaks that have been difficult to control. In some countries, C. auris has emerged as a leading cause of candidemia, accounting for up to 40% of Candida isolates in some hospitals; hospital units have been closed temporarily to stop transmission of C. auris.4

​Invasive aspergillosis

Over 300,000 patients develop IA per year. IA is estimated to have a 50% mortality rate, even with treatment. It is frequently associated with both solid organ and stem cell transplants, as well as the patients with moderate to severe COPD, and is a major complication of lung cancer. Missed diagnosis is frequent.​

Data supports that antibodies protect mice in lethal models of C. albicans and C. auris, an emerging pathogen

New Orleans (PR Newswire), December 9, 2019 – Stadius Biopharma LLC will present data on its fully human antibodies to Candida at the upcoming Antibody Engineering & Therapeutics meeting December 9 – 13, 2019 in San Diego. The antibodies protect mice from death in lethal mouse models of both C. albicans and C. auris.

Human antibodies to two peptides derived from the C. albicans cell wall associated proteins Fba and MET6 are present in human sera. Six fully human recombinant antibodies have been isolated and preliminary characterizations performed. Two of the antibodies, one to the Fba peptide and one to the MET6 peptide, have been tested in animal models and show protection in lethal mouse models for C. albicans and C. auris. The antibodies may function independently of Fc-mediated host functions. These results demonstrate that anti-peptide antibodies to Fba and to MET6 may be useful as human therapeutics for the prophylaxis and treatment of disseminated candidiasis.

“Our data suggests that human antibodies to peptides derived from conserved sequences of novel virulence factors associated with the Candida albicans cell wall will bind and disrupt the pathology of various species of Candida, including C. auris, a deadly pathogen,” said Russell B. Wilson, Ph.D., the Company’s Chief Science Officer. “This is a novel mechanistic approach for the treatment of invasive candidiasis,” he said.

About Invasive Candidiasis

Invasive Candida infection can present with high morbidity and mortality in immunosuppressed populations and is the most frequent hospital infection, accounting for up to 15% of bloodstream infections. Candida species are the main causative agents in 50–70% of systemic fungal infections.

C. auris has emerged as a life-threatening infection and is increasing in incidence worldwide. There are currently no effective agents. It is a significant threat for patients at risk and potentially the general population (

Prophylaxis of Candida can range from months to life-long in higher risk groups in solid organ transplant patients. Current oral medications may involve toxicity as well as lack of compliance and recurrence of infection, resulting in potentially costly and life-threatening outcomes.
