Hyperinflammation triggered by SARS-CoV-2 is a major cause of disease severity, with activated macrophages implicated in this response. OP-101, a hydroxyl-polyamidoamine dendrimer– N -acetylcysteine conjugate that specifically targets activated macrophages, improves outcomes in preclinical models of systemic inflammation and neuroinflammation. In this multicenter, randomized, double-blind, placebo-controlled, adaptive phase 2a trial, we evaluated safety and preliminary efficacy of OP-101 in patients with severe COVID-19. Twenty-four patients classified as having severe COVID-19 with a baseline World Health Organization seven-point ordinal scale of ≥5 were randomized to receive a single intravenous dose of placebo ( n = 7 patients) or OP-101 at 2 ( n = 6), 4 ( n = 6), or 8 mg/kg ( n = 5 patients). All study participants received standard of care, including corticosteroids. OP-101 at 4 mg/kg was better than placebo at decreasing inflammatory markers; OP-101 at 4 and 8 mg/kg was better than placebo at reducing neurological injury markers, (neurofilament light chain and glial fibrillary acidic protein). Risk for the composite outcome of mechanical ventilation or death at 30 and 60 days after treatment was 71% (95% CI: 29%, 96%) for placebo and 18% (95% CI: 4%, 43%; P = 0.021) for the pooled OP-101 treatment arms. At 60 days, 3 of 7 patients given placebo and 14 of 17 OP-101–treated patients were surviving. No drug-related adverse events were reported. These data show that OP-101 was well tolerated and may have potential to treat systemic inflammation and neuronal injury, reducing morbidity and mortality in hospitalized patients with severe COVID-19.

Artesunate (ARS), an artemisinin derivative, has been demonstrated to possess antitumor activity in various human tumor cells. This study aims to investigate the molecular mechanism by which ARS induces apoptosis in human hepatocellular carcinoma cells (Huh-7 and Hep3B cells). ARS effectively induced externalization of phosphatidylserine (PS), depolarization of mitochondrial membrane, release of cytochrome c from mitochondria, and activation of caspase-9 and 3, characteristics of the intrinsic apoptosis. Pretreatment with antioxidant N-Acetyle-Cysteine (NAC) completely blocked ARS-induced reactive oxygen species (ROS) generation and apoptosis in the two cell lines. ARS increased cellular iron ions level in Huh-7/Hep3B cells, but decreased cellular iron ions level in HepG2 cells. Pifithrin-alpha (PFT), an inhibitor of p53, significantly enhanced ARS-induced cytotoxicity in HepG2 cells, and the forced expression of wild-type p53 significantly enhanced ARS-induced cytotoxicity in Hep3B cells. In addition, ARS induced translocation and activation of the proapoptotic Bax, and silencing Bax remarkably inhibited ARS-induced apoptosis and ΔΨm collapse in Huh-7 and Hep3B cells, demonstrating the key role of Bax in ARS-induced apoptosis. Collectively, our data demonstrate that ARS induces ROS-dependent apoptosis via a Bax-mediated intrinsic pathway in Huh-7 and Hep3B cells.

Extreme prematurity is a major risk factor for perinatal and neonatal brain injury, and can lead to white matter injury that is a precursor for a number of neurological diseases, including cerebral palsy (CP) and autism. Neuroinflammation, mediated by activated microglia and astrocytes, is implicated in the pathogenesis of neonatal brain injury. Therefore, targeted drug delivery to attenuate neuroinflammation may greatly improve therapeutic outcomes in models of perinatal white matter injury. In this work, we use a mouse model of ischemia-induced neonatal white matter injury to study the biodistribution of generation 4, hydroxyl-functionalized polyamidoamine dendrimers. Following systemic administration of the Cy5-labeled dendrimer (D-Cy5), we demonstrate dendrimer uptake in cells involved in ischemic injury, and in ongoing inflammation, leading to secondary injury. The sub-acute response to injury is driven by astrocytes. Within five days of injury, microglial proliferation and migration occurs, along with limited differentiation of oligodendrocytes and oligodendrocyte death. From one day to five days after injury, a shift in dendrimer co-localization occurred. Initially, dendrimer predominantly co-localized with astrocytes, with a subsequent shift towards microglia. Co-localization with oligodendrocytes reduced over the same time period, demonstrating a region-specific uptake based on the progression of the injury. We further show that systemic administration of a single dose of dendrimer-N-acetyl cysteine conjugate (D-NAC) at either sub-acute or delayed time points after injury results in sustained attenuation of the 'detrimental' pro-inflammatory response up to 9days after injury, while not impacting the 'favorable' anti-inflammatory response. The D-NAC therapy also led to improvement in myelination, suggesting reduced white matter injury. Demonstration of treatment efficacy at later time points in the postnatal period provides a greater understanding of how microglial activation and chronic inflammation can be targeted to treat neonatal brain injury. Importantly, it may also provide a longer therapeutic window.

In October 2022, eFFECTOR Therapeutics announced the completion of enrollment for the second cohort of a three-cohort Phase Ib clinical trial of zotatifin in non-hospitalized adults with confirmed COVID-19 infection. In October 2022, Pfizer/BioNTech and Moderna's bivalent COVID-19 booster vaccines targeting the BA.4 and BA.5 subvariants of Omicron have been approved for use in children and adolescents in the United States. In October 2022, an intranasal formulation of AstraZeneca's widely used COVID-19 vaccine, Vaxzevria, failed at the first hurdle, with results from a phase I trial revealing that it was unable to stimulate a strong immune response to the virus. In September 2022, Bharat Biotech's Covid-19 vaccine candidate codenamed BBV154, which has now been rechristened iNCOVACC became the world's first intranasal Covid-19 vaccine to be granted emergency use authorization (EUA) after the Indian drug regulator approved it for a two-dose primary immunization of those aged 18 years and above. COVID-19 intranasal vaccine (BBV154) has proven to be safe, well-tolerated, and immunogenic in subjects in controlled clinical trials phase III In July 2022, Revive Therapeutics Ltd. is pleased to provide an update on the Company's U.S. Food & Drug Administration ("FDA") Phase III clinical trial (the "Study") (NCT04504734) to evaluate the safety and efficacy of Bucillamine, an oral drug with anti-inflammatory and antiviral properties, in patients with mild to moderate COVID-19. The Company had unblinded the pre-dose selection data (the "Data") to potentially support the amended Study protocol with the new primary efficacy endpoints. The assigned unblinded statistician team is currently analyzing the Data, and the Company aims to submit the amended Study protocol to the FDA shortly thereafter. The proposed new primary efficacy endpoints may include the rate of sustained clinical resolution of symptoms of COVID-19, which addresses the shift in COVID-19 clinical outcomes observed over the course of the pandemic, and, therefore, to have more meaningful study endpoints for the FDA to consider for potential Emergency Use Authorization In April 2022, Direct Biologics, FDA approved the company to proceed with its Phase III clinical trial using its investigational EV drug, ExoFlo, to treat Acute Respiratory Distress Syndrome (ARDS) due to Covid-19. Direct Biologics is the first and only EV Company to receive FDA Phase III approval for an Investigational New Drug (IND) indication to date In April 2022, Direct Biologics announced that the US Food and Drug Administration (FDA) had awarded their EV drug product ExoFlo with a Regenerative Medicine Advanced Therapy (RMAT) designation for the treatment of Acute Respiratory Distress Syndrome (ARDS) associated with COVID-19. In March 2022, Akston Biosciences Corp and Biolexis, a division of Stelis Biopharma Ltd., entered into a licensing, manufacturing, and commercialization agreement for Akston's AKS-452, a protein subunit COVID-19 vaccine. Biolexis gained the right to manufacture and commercialize AKS-452 (branded as AmbiVax-CTM) in India and over 130 countries in Asia, Latin America, and Africa, largely covering the low-and-middle-income countries (LMICs).

(SARS-CoV-2). COVID-19 causes a respiratory illness similar to the flu. The COVID-19 symptoms include cough, fever, and difficulty breathing. The majority of people infected with the COVID-19 virus will experience mild to moderate respiratory illness and will recover without the need for special care. People over the age of 65 and those with underlying medical conditions such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illnesses. When an infected person coughs or sneezes, the COVID-19 virus is primarily transmitted through saliva or nasal discharge droplets.

It is used to boost the body's production of white blood cells. Sargramostim is given to patients with decreased ability to produce white blood cells. It is also used in some medical procedures (for example, bone marrow/stem cell transplants). It is a supportive medication but does not aid cancer treatment. The product is currently in Phase II/III development for the treatment of COVID-19. Sotrovimab: Vir Biotechnology Vir Biotechnology's Sotrovimab is a monoclonal antibody that neutralizes SARS-CoV-2. The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus that causes SARS), indicating that the epitope is highly conserved, which may make resistance development more difficult. Sotrovimab, which incorporates Xencor, Inc.'s XtendTM technology, has also been designed to achieve high concentrations in the lungs for optimal penetration into SARS-CoV-2-affected airway tissues and to have an extended half-life.

Nanoparticle therapy may help patients hospitalized with severe COVID-19 infections

Researchers say that an experimental dendrimer nanoparticle treatment called OP-101 substantially reduced the risk of death and need for a ventilator in a study of 24 severely ill adults hospitalized with COVID-19. Johns Hopkins Medicine researchers say that an experimental dendrimer nanoparticle treatment called OP-101 substantially reduced the risk of death and need for a ventilator in a study of 24 severely ill adults hospitalized with COVID-19. Results of the small clinical trial, funded by Ashvattha Therapeutics, a Johns Hopkins startup company that makes the drug, specifically found that patients who received the drug had a greater than fourfold higher rate of decrease in biomarkers of inflammation and brain injury circulating in their blood compared with patients who received a placebo. A report on the study was published July 20 in Science Translational Medicine. "OP-101 could be a potent therapy for decreasing hyperinflammation and promoting repair in people with severe COVID, showing significant clinical benefit without the associated side effects typically seen with some other treatments," says Sujatha Kannan, M.B.B.S., professor of anesthesiology and critical care medicine and pediatrics at the Johns Hopkins University School of Medicine. Kannan and her husband, Kannan Rangaramanujam, Ph.D., professor of ophthalmology at the Johns Hopkins University School of Medicine and Wilmer Eye Institute, Johns Hopkins Medicine, developed OP-101 by attaching a powerful antioxidant/anti-inflammatory drug known as n-acetyl cysteine (NAC) to a nanoparticle that is 100,000 times smaller than the thickness of a sheet of paper. Each nanoparticle has a number of molecules of the drug attached to it, and can deliver the drug specifically to inflammatory cells called macrophages. The dendrimer nanoparticle delivers the drug to only those macrophages involved in inflammation at the site of injury. Currently, NAC is used in a different form to treat acetaminophen poisoning and for thinning mucus secretions in airways. The pair of researchers are co-inventors on patents related to the drug's discovery, and founded a biotechnology company, Ashvattha Therapeutics Inc., based in California, to develop the drug and fund clinical trials. The company licenses the technology through Johns Hopkins Technology Ventures. The researchers caution that larger clinical trials of OP-101 must be completed, and that OP-101 should be used to treat COVID-19 only in a clinical trial or, for other medical needs, with the supervision of a physician. For the study, researchers recruited 24 patients between the ages of 43 and 86, mostly male (five Black, 15 Hispanic and four non-Hispanic white) with severe COVID-19 admitted to hospitals between August 2020 and May 2021 within five medical systems located in five states in the U.S., including The Johns Hopkins Hospital. Patients with signs of severe COVID-19 who were on mechanical ventilation or on oxygen through high-flow nasal cannula were eligible to be enrolled in the study. The majority of patients included in the study were in the intensive care unit. Six patients received a single intravenous 2 mg/kg dose of OP-101; six received a 4 mg/kg dose; five received an 8 mg/kg dose and seven received a saline placebo within 24 hours of enrollment. All 24 patients also received standard care for COVID-19, including corticosteroids used to suppress inflammation and the antiviral drug remdesivir. The investigators were not aware which patients received placebo or OP-101 until the end of the study. At the conclusion of the trial, the researchers found that OP-101, at a dosage of either 4 mg/kg or 8 mg/kg, was sixfold better at reducing the inflammation marker C-reactive protein, and fourfold to tenfold better at reducing biomarkers of neurologic injury such as neurofilament light and glial fibrillary acidic protein. The risk of death or needing a ventilator at 30 and 60 days after treatment was 71% for patients who received the placebo and 18% for those receiving OP-101. At 60 days after receiving either OP-101 or the placebo, 3 of 7 patients who received the placebo and 14 of 17 patients who received any of the three doses of OP-101 had survived. OP-101 was not associated with any adverse events, and was well tolerated in this critically ill population. "It is possible that OP-101 may also be useful in treating the neurologic, cardiac and respiratory symptoms associated with long COVID, since a proportion of patients with long COVID have persistent inflammation," says Rangaramanujam Kannan. The researchers are planning larger clinical trials of OP-101.

Ashvattha Therapeutics Announces Publication of Data in Science Translational Medicine from Phase 2a Clinical Trial for OP-101 in Severe COVID-19

REDWOOD CITY, Calif., July 25, 2022 (GLOBE NEWSWIRE) -- Ashvattha Therapeutics (“Ashvattha”), a clinical stage company developing novel hydroxyl dendrimer therapeutics, today announced the publication of the results from a Phase 2a clinical study demonstrating a significant reduction in inflammatory and neuroinflammatory markers and improved clinical outcomes with OP-101, a hydroxyl dendrimer therapeutic (HDT), delivered intravenously in patients with severe COVID-19. The paper, titled, “Dendrimer nanotherapy for severe COVID-19 attenuates inflammation and neurological injury markers and improves outcomes in a phase 2a clinical trial,” was published in the peer-reviewed scientific journal Science Translational Medicine. The Phase 2a trial (PRANA), a multi-center, double-blind, placebo-controlled, single sequential, ascending dose study, evaluated the safety, tolerability and preliminary efficacy of OP-101 intravenously dosed at 2 mg/kg, 4 mg/kg and 8 mg/kg across three cohorts compared to a single intravenous dose of placebo in patients with severe COVID-19. Key findings published in Science Translational Medicine include: OP-101 was shown to improve survival, corresponding with an increase in dosage (2 mg/kg: 67%; 4 mg/kg: 100%; 8 mg/kg: 80%) versus placebo (43%). Risk for the composite outcome of mechanical ventilation or death at 30 and 60 days after treatment was 71% for placebo and 18% for the pooled OP-101 treatment arms. At 60 days, three of seven patients given placebo and 14 of 17 OP-101 treated patients were surviving, and the surviving patients treated with OP-101 did not require mechanical ventilation by day 30 or day 60. Treatment with OP-101 was associated with attenuating neuronal injury markers NfL and GFAP, lasting until day 30 of the study. OP-101 dosed at 4 mg/kg treatment significantly decreased markers of hyperinflammation TNF-α, IL-6 and IL-8. No drug-related adverse events were reported. “We are incredibly pleased with these positive results that support the potential of OP-101 to significantly improve clinical outcomes and survival for patients with severe COVID-19,” said Jeffrey Clelland, Ph.D., Chairman & CEO of Ashvattha Therapeutics. “This data also validates the ability of our hydroxyl dendrimer therapies to cross tissue barriers, including blood-brain barriers, selectively targeting areas of inflammation with an excellent safety profile, which could benefit patients with other diseases characterized by inflammation. We are hopeful that we may see similar results in patients suffering from Long COVID.” This paper was published in its entirety in volume 14, issue number 654 of Science Translational Medicine and can be accessed here. About OP-101 OP-101 is an HDT with N-acetyl cysteine (NAC) that selectively targets reactive macrophages and microglia, which are responsible for hyperinflammation, lung injury and multi-organ failure caused by viral or bacterial infections, including COVID-19. About Ashvattha Therapeutics Ashvattha Therapeutics is a clinical-stage biotech company developing novel hydroxyl dendrimer therapeutics (HDTs) targeting unmet medical needs in ophthalmology, neurology, inflammatory diseases and neuro-oncology. The therapies are based on hydroxyl dendrimers (HDs), a targeted platform technology exclusively licensed from our founders, Kannan Rangaramanujam and Sujatha Kannan at Johns Hopkins University. HDs chemically conjugated to disease-modifying drugs create novel proprietary HD therapeutics (HDTs) selectively targeting reactive inflammatory cells in disease tissue with localized sustained effects. Ashvattha has initiated multiple programs with HDTs focused on neurology, ocular neovascular disease including neovascular age-related macular degeneration (AMD) and diabetic macular edema (DME), and hyperinflammation in diseases.
