New vaccine platform used to develop COVID-19 candidates

0

April 07, 2020: “As of this morning – Tuesday April 7 – the current recorded case count for COVID-19 (coronavirus) in the UK has hit 51,608 with 5,373 deaths. UK biotech Imophoron says it has produced multiple COVID-19 vaccine candidates based on its novel vaccine platform ADDomer.


Having joined the University of Bristol’s COVID-19 Emergency Research (UNCOVER) Group, the start-up confirmed preclinical trials of these vaccines will begin “within weeks”. Imophoron is developing a new, “highly adaptable, easy-to-manufacture, rapid-response platform” for vaccines to combat present and future infectious diseases. Vaccines based on the ADDomer platform are likely to require no adjuvant, no refrigeration and have reduced risk of side effects, it said.”

“COVID-19 infects cells using its so-called `Spike’ protein. Most COVID-19 vaccines now being fast-tracked present the complete Spike to the immune system, which reacts by making antibodies. This approach risks inducing antibodies that bind to the wrong parts of the Spike and could make the disease even worse. Imophoron’s vaccines, in contrast, present only very specific parts of the Spike essential for cell entry and are potentially much less prone to this risk,” commented Professor Imre Berger, co-founder at Imophoron and director of the University’s Max Planck-Bristol Centre for Minimal Biology.

“The company also revealed that it is looking for partners to further the development of the COVID-19 candidates and the ADDomer platform.

Izana intiates study assessing namilumab for COVID-19

0

April 06, 2020: “As of this morning – Monday April 5 – the current recorded case count for COVID-19 (coronavirus) in the UK has hit 47,806 with 4,934 deaths.

Oxford, UK-based biopharma Izana Bioscience has announced the initiation of a two-centre compassionate use study involving namilumab (IZN-101) in the treatment of patients with rapidly worsening COVID-19 in cooperation with the Humanitas research group.

Namilumab is the company’s Phase III-ready, fully human monoclonal antibody therapy targeting granulocyte-macrophage colony stimulating factor (GM-CSF), currently in late-stage clinical development for the treatment of rheumatoid arthritis and ankylosing spondylitis.

GM-CSF is a pro-inflammatory cytokine that plays a central role in a broad range of immune-mediated diseases. The cytokine has been found in higher levels of COVID-19 ICU patients, according to recent data from China suggesting that early intervention could be beneficial in patients with rapidly worsening COVID-19, the firm noted.”

“The compassionate use programme will gather data from hospitalised, rapidly worsening COVID-19 patients, and has the overall objective of treating them before they are admitted to intensive care or require ventilation.

It also aims to support namilumab’s future development for the treatment of COVID-19, and discussions with global regulatory authorities, including the UK, are in progress.

The study will take place in Italy under the leadership of Professor Carlo Selmi, head of the Rheumatology and Clinical Immunology Unit at Humanitas Research Hospital and Associate Professor of Internal Medicine at Humanitas University.”

He said: “Clinicians working on the frontline urgently require new treatment options for their seriously ill COVID-19 patients. Anti-GM-CSF therapies such as namilumab could play an important role in how we can prevent or reduce the deterioration in COVID-19 patients for which there are currently few treatments available. Ergomed plc, a CRO specialised in providing bespoke solutions and research services to the pharmaceutical industry, is facilitating this programme.”

Novartis announces plan to initiate clinical study of Jakavi® in severe COVID-19 patients and establish international compassionate use program

0

Apr 02, 2020: “Novartis  announced plans to initiate a Phase III clinical trial in collaboration with Incyte to evaluate the use of Jakavi® (ruxolitinib) for treatment of a type of severe immune overreaction called cytokine storm that can lead to life-threatening respiratory complications in patients with COVID-19.

The decision is based on pre-clinical evidence and preliminary reports from independent studies, and is supported by extensive data on the safety and efficacy of Jakavi in conditions like acute graft versus host disease and myeloproliferative neoplasms.

The proposed trial will assess Jakavi in combination with standard of care (SoC) therapy, compared to SoC therapy alone, in patients with severe COVID-19 pneumonia as a result of SARS-CoV-2 infection.”

“Novartis is taking a number of steps to address the urgent needs arising from the COVID-19 pandemic, including the evaluation of our existing therapies to assess if any can be utilized beyond their approved indications,” said John Tsai, Head Global Drug Development and Chief Medical Officer, Novartis. “The potential that Jakavi could lead to faster recovery times for COVID-19 patients with fewer requiring intensive care and mechanical ventilation is encouraging and absolutely merits further investigation. We now are moving rapidly to finalize the study plan and then to enroll eligible patients, as well as put in place a process to provide access for patients unable to participate in the trial.”

“Given the rapid spread of the pandemic, and as plans for the study are finalized, Novartis also has set up an international compassionate use program for eligible patients, subject to local regulations. In addition, we are taking steps to manage the anticipated increase in COVID-19 related requests for Jakavi without interrupting access for patients taking the drug for its licensed indications. In the US, ruxolitinib access requests are coordinated by Incyte.”

Novartis commitment and response to COVID-19
“Novartis is deeply dedicated to the global effort to combat COVID-19 and doing our part to support the stability of global healthcare systems. We announced a broad set of measures including the creation of a global fund of USD 20 million to support communities around the world impacted by the COVID-19 pandemic. Novartis also has committed 130 million doses of hydroxychloroquine to support pandemic response. In addition, Novartis joined two key cross-industry research initiatives, the COVID-19 Therapeutics Accelerator, coordinated by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard, as well as a COVID-19 directed partnership organized by the Innovative Medicines Initiative (IMI). Novartis is separately supporting COVID-19 related clinical investigations of several Novartis medicines. To support access, the Novartis generics and biosimilars division Sandoz became the first company to commit to keeping stable prices for a basket of essential medicines that may help in the treatment of COVID-19. More information about the Novartis response to COVID-19 is available on Novartis.com/coronavirus.”

FDA Accepts IND for NK Cell Therapy CYNK-001 to Treat Patients with COVID-19

0

April 03, 2020: “The FDA cleared the investigational new drug (IND) application for the use of CYNK-001 in adults with coronavirus disease 2019 (COVID-19), according to Celularity, the agent’s manufacturer. The company also announced that it will immediately begin a phase I/II clinical study of CYNK-001 in collaboration with Sorrento Therapeutics, which will include up to 86 patients with COVID-19.”

“We are confident that our strategic relationship with Sorrento will help assure our ability to meet the scale requirements for our efforts in COVID-19,” Robert Hariri, MD, PhD, CEO for Celularity, said in a press release.

“Individuals who are enrolled in the trial will receive infusions of natural killer (NK) cells, which the company believes could kill cells infected with the virus and address the resulting inflammation caused by the immune system. Infectious Disease Research Institute (IDRI), a nonprofit based in Seattle, says it is coordinating the trial, which will take place at medical centers in the US.”

“To date, efforts to treat COVID-19 cases have been primarily focused on antiviral medications,” Corey Casper, MD, MPH, clinical professor of global health and medicine at the University of Washington and interim president and CEO at IDRI, said in a press release. “While these are important, patients with serious disease may not respond completely to antiviral medications because they are experiencing damage already inflicted on the body’s vital organs.”

CYNK-001 is the only cryopreserved allogeneic, off-the-shelf NK cell therapy being developed from placental hematopoietic stem cells. The company suggests that using such cells eliminates the risk of an immune system reaction that other kinds of donor cells can cause. The therapy is already being tested in patients with acute myeloid leukemia and multiple myeloma in early-stage studies, and as a potential treatment option for various solid tumors.”

“In January, the FDA cleared Celularity’s investigational new drug (IND) application for CYNK-001 in patients with glioblastoma multiforme (GBM). The clinical trial is anticipated to be the first clinical trial in the US to investigate intratumoral administration of an allogeneic NK cell therapy.”

“The FDA clearance of our IND validates the versatility of our allogeneic, off-the-shelf, placental-derived NK cell therapy platform to generate novel clinical candidates against a broad range of devastating cancers,” Hariri said in a press release. “This IND represents a significant step toward a potential immunotherapy option that is more accessible and tolerable to patients with glioblastoma multiforme.”

“According to the company, they expect to initiate first-in-human clinical testing of CYNK-001 administered either intravenously or intratumorally. The study is anticipated to evaluate the safety, feasibility, and tolerability of multiple doses of CYNK-001 in patients with relapsed GBM.”

Nonclinical safety and efficacy data were presented at the 2019 Society for Neuro-Oncology (SNO) Annual Meeting, demonstrating that a single administration of CYNK-001 was well-tolerated and showed enhanced in vivo anti-tumor activity against GBM.” https://www.cancernetwork.com/immuno-oncology/fda-accepts-ind-nk-cell-therapy-cynk-001-treat-patients-covid-19

Coronavirus (COVID-19) Update: FDA Continues to Accelerate Development of Novel Therapies for COVID-19

0

On 31-Mar-2020, FDA announced that ” As part of the Trump Administration’s all-hands-on-deck approach across public, academic and private sectors to combat the COVID-19 pandemic, the U.S. Food and Drug Administration stood up a new program to expedite the development of potentially safe and effective life-saving treatments.

The program, known as the Coronavirus Treatment Acceleration Program (CTAP), is using every tool at the agency’s disposal to bring new therapies to sick patients as quickly as possible, while at the same time supporting research to further evaluate whether these medical countermeasures are safe and effective for treating patients infected with this novel virus.

The FDA is announcing a new, comprehensive public-private approach to bring coronavirus treatments to market as fast as possible,” said HHS Secretary Alex Azar.

“As part of this new program, the FDA is cutting red tape, redeploying staff and working day and night to review requests from companies, scientists and doctors who are working toward therapies.

We are grateful to the men and women of the FDA who have been working in concert with industry and other parts of HHS to support potential coronavirus treatments for weeks now. Each day, President Trump’s all-of-America approach is making progress and providing new hope in our fight against the coronavirus

There are a large number of companies and researchers developing and evaluating COVID-19 related therapies. Given the urgent nature of the pandemic, under the FDA’s accelerator program, staff from the Center for Drug Evaluation and Research and the Center for Biologics Evaluation and Research are providing regulatory advice, guidance and technical assistance as quickly as possible. As part of this work, the FDA is triaging requests from developers and scientists seeking to develop new drug and biologic therapies, getting the relevant FDA staff in touch with them and providing rapid, interactive input to get studies underway quickly. For example, the FDA has reviewed study protocols within 24 hours in many cases and has reviewed single-patient expanded access requests generally within three hours. The FDA is also collaborating with federal partners, developers and researchers to create protocols that can be used across institutions and programs to streamline efforts.

Quickly after the emergence of this virus, we began working directly with federal health partners, academia and industry to advance medical countermeasures against COVID-19. Our staff continues to work across all sectors to expedite the development of numerous, innovative potential prevention and treatment approaches. We are also looking at pragmatic and expedited ways to make these products available to patients, while still ensuring the FDA’s standards are met,” said FDA Commissioner Stephen M. Hahn. “Accelerating the investigation of products that could potentially benefit people affected by the COVID-19 pandemic is one of the FDA’s highest priorities. We want to help patients by expediting promising treatments and are committed to maximizing our regulatory flexibility and proactively bringing the best innovators together to ensure we are getting the right treatments to the right patients at the right time.

To support these goals, the FDA has, among other things, redeployed medical and regulatory staff to serve on review teams dedicated to COVID-19 therapies, streamlined processes and operations for developers and scientists to send inquiries and requests and provided resources to health care providers and researchers to help them submit emergency requests to use investigational products.

There are a variety of therapeutic areas being evaluated, including antiviral drugs like remdesivir that might treat the specific virus, as well as host targets, such as interleukin-6 (IL-6) receptor inhibitors that may be helpful in reducing lung inflammation and improving lung function in COVID-19 patients. There’s also interest in examining whether therapies such as convalescent plasma and hyperimmune globulin, antibody-rich blood products that are taken from blood donated by people who have recovered from the virus, could shorten the length or lessen the severity of the illness. Work is also ongoing to evaluate whether existing therapies such as chloroquine and hydroxychloroquine (with or without other medications) help treat patients with COVID-19.

The FDA also recognizes the potential for many different real-world data sources to complement traditional clinical studies and speed the process of evaluating the impact of potential COVID-19 therapies. To that end, the agency is advancing relationships with partners in the public and private sectors to rapidly collect and analyze information in areas such as illness patterns and treatment outcomes.

The FDA’s efforts to facilitate the development of COVID-19 therapies are focused on expediting the development of data on these medical countermeasures that can meet the agency’s world-respected gold standard for full FDA approval, which relies on data from adequate and well-controlled trials to most efficiently determine if an experimental treatment can safely and effectively benefit patients.

The FDA will continue to enhance and expand its work across the federal government and innovators in academia and industry to accelerate COVID-19 treatments and other medical countermeasures. The agency will outline additional information in the near future to provide a greater understanding of the full breadth of work in this area, to the extent permitted by confidentiality laws.

The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.

Sanofi: First patient outside U.S. treated in global Kevzara® (sarilumab) clinical trial program for patients with severe COVID-19

0

On 30-Mar-2020, Sanofi announced that “The first patient outside of the U.S. has been treated as part of a global clinical program evaluating Kevzara® (sarilumab) in patients hospitalized with severe COVID-19. The global clinical program has now been initiated in Italy, Spain, Germany, France, Canada, Russia and the United States – all countries that have been impacted by COVID-19.

Clinical trial

This is the second multi-center, double-blind, Phase 2/3 trial as part of the Kevzara COVID-19 program, and the companies are continuing to work with health authorities around the world to secure initiation at additional sites. This follows Sanofi and Regeneron’s announcement earlier this month of the initiation of the first trial, which is U.S.-based.

Sanofi and Regeneron are relentlessly working to rapidly initiate trials around the world that will help determine whether Kevzara has the potential to play a role in addressing the COVID-19 global health crisis. These trials will provide important data to determine whether Kevzara ameliorates the life-threatening complications of COVID-19 infections by counteracting the overactive inflammatory responses in the lungs when damaged by the virus. In these unprecedented times, we are deeply grateful for the daily collaboration with health authorities that are enabling us to conduct this clinical work so quickly,” said John Reed, M.D., Ph.D., Sanofi’s Global Head of Research and Development. “In addition to this clinical trial aiming to help critically ill COVID-19 patients, our work continues to bring forth a vaccine for disease prevention, along with efforts to provide other important Sanofi medicines that may help patients impacted by COVID-19.

Mechanism of action

Kevzara is a fully-human monoclonal antibody that inhibits the interleukin-6 (IL-6) pathway by binding and blocking the IL-6 receptor. IL-6 may play a role in driving the overactive inflammatory response in the lungs of patients who are severely or critically ill with COVID-19 infection. The role of IL-6 is supported by preliminary data from a single-arm study in China using another IL-6 receptor inhibitor.

Data from a single-arm study in China suggest that the interleukin-6 pathway may play an important role in the overactive inflammatory response in the lungs of patients with COVID-19. Despite this encouraging finding, it’s imperative to conduct a properly designed, randomized trial to understand the true impact of Kevzara, which we are now doing through this global clinical trial program,” said George D. Yancopoulos, M.D., Ph.D., Co-founder, President and Chief Scientific Officer of Regeneron. “In addition to the Kevzara program, Regeneron continues to rapidly advance a novel antibody cocktail for the prevention and treatment of COVID-19.

The trial outside of the U.S. will assess the safety and efficacy of adding a single intravenous dose of Kevzara to usual supportive care, compared to supportive care plus placebo. The trial has an adaptive design with two parts and is anticipated to enroll approximately 300 patients. The trial will recruit hospitalized patients from several countries who are severely or critically ill with COVID-19 infection.

Scientists have preliminary evidence that IL-6 may play a key role in driving the inflammatory immune response that causes acute respiratory distress syndrome (ARDS) in patients critically ill from COVID-19. In an initial, non-peer-reviewed case series from China, a 21-patient cohort of COVID-19 patients experienced rapidly reduced fevers and 75% of patients (15 out of 20) reduced their need for supplemental oxygen within days of receiving another IL-6 receptor antibody (tocilizumab). Based on these results, China updated its COVID-19 treatment guidelines and approved the use of that IL-6 inhibitor to treat patients with severe or critical disease.

The use of Kevzara to treat the symptoms of COVID-19 is investigational and has not been evaluated by any regulatory authority.

Trial Design

This Phase 2/3, randomized, double-blind, placebo-controlled trial uses an adaptive design to evaluate the safety and efficacy of Kevzara in adults hospitalized with serious complications from COVID-19. To enter the trial, patients must have pneumonia and be hospitalized with laboratory-confirmed COVID-19 that is classified as severe or critical, or who are suffering from multi-organ dysfunction. After receiving the study dose, patients will be assessed for 60 days, or until hospital discharge or death.

In the Phase 2 part of the trial, patients will be randomized 2:2:1 into three groups: Kevzara higher dose, Kevzara lower dose and placebo.

The Phase 2 findings will be utilized in an adaptive manner to determine transition into Phase 3, helping to determine the endpoints, patient numbers and doses.

If the trial continues with all three treatment arms to the end, it is expected to enroll approximately 300 patients, depending on the status of the COVID-19 outbreak and the proportion of patients with severe COVID-19.”

About Kevzara® (sarilumab) Injection

Kevzara is currently approved in multiple countries to treat adults with moderately to severely active rheumatoid arthritis who have not responded to or tolerated previous therapy.

Kevzara was jointly developed by Sanofi and Regeneron under a global collaboration agreement.  Kevzara is a fully-human monoclonal antibody. Kevzara binds specifically to the IL-6 receptor and has been shown to inhibit IL-6-mediated signalling. IL-6 is an immune system protein produced in increased quantities in patients with rheumatoid arthritis and has been associated with disease activity, joint destruction and other systemic problems. Kevzara is being investigated for its ability to reduce the overactive inflammatory immune response associated with COVID-19 based on evidence of markedly elevated levels of IL-6 in severely ill patients infected with coronaviruses.”

Amgen And Adaptive Biotechnologies Announce Strategic Partnership To Develop A Therapeutic To Prevent Or Treat COVID-19

0
On 02-April-2020, “Amgen and Adaptive technologies announced a collaboration aimed at helping address the COVID-19 pandemic.

The companies will combine expertise to discover and develop fully human neutralizing antibodies targeting SARS-CoV-2 to potentially prevent or treat COVID-19. 

The mutually exclusive collaboration brings together Adaptive’s proprietary immune medicine platform for the identification of virus-neutralizing antibodies with Amgen’s expertise in immunology and novel antibody therapy development.

Given the rapidly rising incidence of COVID-19 around the world, the companies will begin work immediately and finalize financial details and terms in the coming weeks. “

Neutralizing antibodies defend healthy cells by interfering with the biological function of an invading virus.

These antibodies may be used therapeutically to treat someone currently fighting the disease and can be given to people who have heightened risk of exposure to SARS-CoV-2, such as healthcare workers.

Adaptive will extend its high throughput platform to rapidly screen the massive genetic diversity of the B cell receptors from individuals that have recovered from COVID-19.

This enables the identification of tens of thousands of naturally occurring antibodies from survivors of COVID-19 to select those that neutralize SARS-CoV-2. 

Amgen will then leverage its world-class antibody engineering and drug development capabilities to select, develop and manufacture antibodies designed to bind and neutralize SARS-CoV-2. deCODE Genetics, a subsidiary of Amgen located in Iceland, will provide genetic insights from patients who were previously infected with COVID-19.

The two companies have signed a Memorandum of Understanding to enable the parties to start work immediately and are planning to execute a Collaboration and License Agreement. Terms of the agreement are not being disclosed.

Both companies aim to accelerate the development of a potential antibody against COVID-19 as fast as possible for patients in need.”

Coronavirus (COVID-19) Update: FDA Coordinates National Effort to Develop Blood-Related Therapies for COVID-19

0

On 03-April-2020, The U.S. Food and Drug Administration continues to play a critical role in accelerating medical countermeasures to treat and prevent COVID-19.

As part of the response to this pandemic, the agency is taking the lead on a national effort to facilitate the development of, and access to, two investigational therapies derived from human blood.

These are called convalescent plasma and hyperimmune globulin and are antibody-rich blood products made from blood donated by people who have recovered from the virus. The products can be administered to individuals diagnosed with COVID-19.

There are some limited data to suggest that convalescent plasma and hyperimmune globulin may have benefit in the COVID-19 illness. This is why evaluation of these therapies in the context of a clinical trial and expanded access program is so important.

Based on prior experience with respiratory viruses and on dataExternal Link Disclaimer that have emerged from China, these products have the potential to lessen the severity or shorten the length of illness caused by COVID-19.

The FDA is facilitating access to convalescent plasma for treating COVID-19 using multiple pathways. The agency’s initial effort was focused on facilitating access to convalescent plasma for the treatment of COVID-19 disease through an emergency investigational new drug application (eIND) process.

The FDA has provided information to help health care providers submit these applications to treat individual patients. The agency also is facilitating the conduct of well-controlled clinical trials at academic institutions to rigorously evaluate the safety and efficacy of convalescent plasma.

Notably, the FDA has led an effort, working collaboratively with our industry, academic, and government partners to develop and implement a protocol that will provide convalescent plasma to patients in need across the country who may not have access to institutions with clinical trials in place.

This will allow for a simplified process for providers that will help to ensure patient safety, while also allowing for the collection of needed information about product efficacy. In this partnership, the Mayo ClinicExternal Link Disclaimer will serve as the lead institution for the program and the American Red Cross will help collect plasma and distribute it for use in patients across the country.

The program was developed with funding from the Biomedical Advanced Research and Development Authority (BARDA), a component of the U.S. Department of Health and Human Services’ Office of the Assistant Secretary of Preparedness and Response.

The FDA anticipates that this collaborative effort will be able to move thousands of units of plasma to the patients who need them in the coming weeks.

The agency is also working with industry and its government partners to accelerate the development and availability of hyperimmune globulin for investigation for the potential treatment COVID-19.

Hyperimmune globulin is a biological product manufactured from convalescent plasma. The FDA is helping to coordinate a study of hyperimmune globulin that will be conducted by the National Institute of Allergy and Infectious Diseases of the National Institutes of Health, as well as coordinating other efforts in this area.

The FDA continues to provide advice, guidance, and technical assistance to help expedite the development of these products and intends to use regulatory flexibility in making these products and other critical medical countermeasures available to prevent and treat COVID-19.

People who have fully recovered from COVID-19 for at least two weeks are encouraged to consider donating plasma, which could potentially help save the lives of up to four patients. Those willing to donate are urged to visit the American Red Cross website at www.redcrossblood.org/plasma4covidExternal Link Disclaimer or contact their local blood donor or plasma collection center.

The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices.

Imfinzi approved in the US for extensive-stage small cell lung cancer

0

On 30-Mar-2020, AstraZeneca announced that “its Imfinzi (durvalumab) has been approved in the US as a 1st-line treatment for adult patients with extensive-stage small cell lung cancer (ES-SCLC) in combination with standard-of-care (SoC) chemotherapies, etoposide plus either carboplatin or cisplatin (platinum-etoposide).

The approval by the Food and Drug Administration was based on positive results from the Phase III CASPIAN trial showing Imfinzi in combination with SoC platinum-etoposide demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) versus SoC alone

SCLC is a highly aggressive, fast-growing form of lung cancer that typically recurs and progresses rapidly despite initial response to chemotherapy.”

Phase III trial:

“The Phase III CASPIAN trial had two primary endpoints comparing experimental arms to SoC. In the Imfinzi plus SoC arm, the risk of death was reduced by 27% (equal to a hazard ratio of 0.73; 95% CI 0.59-0.91; p=0.0047), with median OS of 13.0 months versus 10.3 months for SoC alone. Results also showed an increased confirmed objective response rate in the Imfinzi plus SoC arm (68% versus 58% for SoC alone). The safety and tolerability for Imfinzi plus SoC was consistent with the known safety profiles of these medicines. The Imfinzi plus SoC data from the CASPIAN trial were published in The Lancet.

The second experimental arm testing tremelimumab added to Imfinzi and SoC recently completed, but did not meet its primary endpoint. Details will be presented at a forthcoming medical meeting.

The CASPIAN trial used a fixed dose of Imfinzi (1500mg) administered every three weeks for four cycles while in combination with chemotherapy and then every four weeks until disease progression. As part of a broad development programme, Imfinzi is also being tested following concurrent chemoradiation therapy in patients with limited-stage SCLC in the Phase III ADRIATIC trial with data anticipated in 2021.

Imfinzi received its first approval based on the Phase III CASPIAN trial in Singapore for patients with ES-SCLC in February 2020. Imfinzi in combination with etoposide and either carboplatin or cisplatin is currently under regulatory review for the treatment of ES-SCLC in the 1st-line setting based on the Phase III CASPIAN trial in the EU and Japan.”

Trial Design:

“CASPIAN was a randomised, open-label, multi-centre, global, Phase III trial in the 1st-line treatment of 805 patients with ES-SCLC. The trial compared Imfinzi in combination with etoposide and either carboplatin or cisplatin chemotherapy, or Imfinzi and chemotherapy with the addition of a second immunotherapy, tremelimumab, versus chemotherapy alone. In the experimental arms, patients were treated with four cycles of chemotherapy. In comparison, the control arm allowed up to six cycles of chemotherapy and optional prophylactic cranial irradiation. The trial was conducted in more than 200 centres across 23 countries, including the US, in Europe, South America, Asia and the Middle East. The primary endpoint was OS in each of the two experimental arms”

Mechanism of Action:

Imfinzi (durvalumab) is a human monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, countering the tumour’s immune-evading tactics and releasing the inhibition of immune responses.

Imfinzi is approved in the curative-intent setting of unresectable, Stage III NSCLC after chemoradiation therapy in the US, Japan, China, across the EU and in many other countries, based on the Phase III PACIFIC trial. Imfinzi is approved for the 1st-line treatment of ES-SCLC in combination with SoC chemotherapy in the US and Singapore. Imfinzi is also approved for previously treated patients with advanced bladder cancer in the US and a small number of other countries.

As part of a broad development programme, Imfinzi is also being tested as a monotherapy and in combination with tremelimumab, an anti-CTLA4 monoclonal antibody and potential new medicine, as a treatment for patients with NSCLC, SCLC, bladder cancer, head and neck cancer, liver cancer, biliary tract cancer, cervical cancer and other solid tumours.”

Farxiga reduced the incidence of heart failure worsening or cardiovascular death in a sub-analysis from landmark Phase III DAPA-HF trial

0

On 28-Mar-2020, AstraZeneca announced that “new data from a sub-analysis of the landmark Phase III DAPA-HF (Dapagliflozin And Prevention of Adverse-outcomes in Heart Failure) trial showed that AstraZeneca’s Farxiga (dapagliflozin) reduced the incidence of the primary composite endpoint of heart failure (HF) worsening or cardiovascular (CV) death compared to placebo, in patients with heart failure with reduced ejection fraction (HFrEF), irrespective of their background therapy (i.e. other medications for heart failure).

Farxiga was evaluated in patients who were receiving a broad range of pharmacological treatments, device therapies and cardiac resynchronisation therapy for HFrEF. A consistent reduction in the primary outcome was observed across all these treatment subgroups.

The results were made available at the American College of Cardiology’s 69th Annual Scientific Session Together with World Congress of Cardiology (ACC.20/WCC) and were published in the European Heart Journal.

Farxiga is indicated as a monotherapy and as part of combination therapies to improve glycaemic control in adults with type-2 diabetes (T2D). In the US it is also approved to reduce the risk of hospitalisation for HF in patients with T2D and established CV disease or multiple CV risk factors.

In January 2020, the US Food and Drug Administration (FDA) accepted a supplemental New Drug Application (sNDA) and granted Priority Review for Farxiga to reduce the risk of CV death or the worsening of HF in adults with HFrEF with and without T2D. The Prescription Drug User Fee Act date, the FDA action date for this supplemental application, is scheduled for the second quarter of 2020.”

Farxiga Phase III DAPA-CKD trial will be stopped early after overwhelming efficacy in patients with chronic kidney disease

Farxiga Phase III DAPA-CKD trial will be stopped early after overwhelming efficacy in patients with chronic kidney disease

0

On 30-Mar-2020, AstraZeneca announced that “The Dapagliflozin And Prevention of Adverse outcomes in Chronic Kidney Disease (DAPA-CKD) Phase III trial for Farxiga (dapagliflozin) in patients with chronic kidney disease (CKD) will be stopped early following a recommendation from an independent Data Monitoring Committee (DMC) based on its determination of overwhelming efficacy.”

Reson to stop the trial:

“The decision to stop the trial early was made following a routine assessment of efficacy and safety which showed Farxiga’s benefits earlier than originally anticipated and AstraZeneca will now initiate closure of the trial.”

The objective of the Trail:

“The primary endpoint of DAPA-CKD is a composite of worsening of renal function or death (defined as a composite endpoint of ≥50% sustained decline in estimated glomerular filtration rate (eGFR), the onset of end-stage kidney disease (ESKD) or cardiovascular (CV) or renal death) in patients with CKD irrespective of the presence of type-2 diabetes (T2D)”

“The full results will be submitted for presentation at a forthcoming medical meeting and AstraZeneca will now initiate discussions with global health authorities regarding early regulatory submissions.

In August 2019, the US Food and Drug Administration (FDA) granted Fast Track designation for the development of Farxiga to delay the progression of renal failure and prevent CV and renal death in patients with CKD. Farxiga is under Priority Review with the FDA and under regulatory review at the European Medicines Agency (EMA), as well as in other regions, for the treatment of patients with heart failure (HF).”
