"The approval of ADCETRIS in combination with CHP for use in the European Union for patients with previously untreated sALCL represents a significant advance for patients who previously were treated with CHOP chemotherapy regimen that was often unsuccessful in leading to long-term remissions," said Clay Siegall, Ph.D., President and Chief Executive Officer at Seattle Genetics. "The outstanding results from the ECHELON-2 phase 3 trial, which demonstrated superior progression-free survival and overall survival compared to CHOP, led to this important regulatory milestone. We are pleased that our partner Takeda is able to make this clinically meaningful therapeutic option available to patients in Europe."

The results from the ECHELON-2 phase 3 clinical trial were published in The Lancetin December 2018. The marketing authorization for ADCETRIS is valid in all countries of the European Union, Norway, Liechtenstein and Iceland.

About T-Cell Lymphomas

There are more than 60 subtypes of non-Hodgkin lymphomas which are broadly divided into two major groups: B-cell lymphomas, which develop from abnormal B-lymphocytes, and T-cell lymphomas, which develop from abnormal T-lymphocytes. There are many different forms of T-cell lymphomas, some of which are extremely rare. T-cell lymphomas can be aggressive (fast-growing) or indolent (slow-growing). PTCL accounts for approximately 10 percent of non-Hodgkin lymphoma cases in the U.S. and Europe and may be as high as 24 percent in parts of Asia.

About ADCETRIS

ADCETRIS is being evaluated broadly in more than 70 clinical trials in CD30-expressing lymphomas. These include three completed phase 3 trials: ECHELON-2 trial in frontline peripheral T-cell lymphomas, ECHELON-1 in previously untreated Hodgkin lymphoma, and ALCANZA in cutaneous T-cell lymphoma.

ADCETRIS is an ADC comprising an anti-CD30 monoclonal antibody attached by a protease-cleavable linker to a microtubule disrupting agent, monomethyl auristatin E (MMAE), utilizing Seattle Genetics’ proprietary technology. The ADC employs a linker system that is designed to be stable in the bloodstream but to release MMAE upon internalization into CD30-expressing cells.

ADCETRIS for injection for intravenous infusion has received FDA approval for six indications in adult patients with: (1) previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with cyclophosphamide, doxorubicin, and prednisone, (2) previously untreated Stage III or IV classical Hodgkin lymphoma (cHL), in combination with doxorubicin, vinblastine, and dacarbazine, (3) cHL at high risk of relapse or progression as post-autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation, (4) cHL after failure of auto-HSCT or failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates, (5) sALCL after failure of at least one prior multi-agent chemotherapy regimen, and (6) primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.

Health Canada granted ADCETRIS approval with conditions in 2013 for patients with (1) HL after failure of autologous stem cell transplant (ASCT) or after failure of at least two multi-agent chemotherapy regimens in patients who are not ASCT candidates and (2) sALCL after failure of at least one multi-agent chemotherapy regimen. Non-conditional approval was granted for (3) post-ASCT consolidation treatment of patients with HL at increased risk of relapse or progression in 2017, (4) adult patients with pcALCL or CD30-expressing MF who have received prior systemic therapy in 2018, (5) for previously untreated patients with Stage IV HL in combination with doxorubicin, vinblastine, and dacarbazine in 2019, and (6) for previously untreated adult patients with sALCL, peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) or angioimmunoblastic T-cell lymphoma (AITL), whose tumors express CD30, in combination with cyclophosphamide, doxorubicin, prednisone in 2019.

ADCETRIS received conditional marketing authorization from the European Commission in October 2012. The approved indications in Europe are: (1) for the treatment of adult patients with relapsed or refractory CD30-positive Hodgkin lymphoma following ASCT, or following at least two prior therapies when ASCT or multi-agent chemotherapy is not a treatment option, (2) for the treatment of adult patients with relapsed or refractory sALCL, (3) for the treatment of adult patients with CD30-positive Hodgkin lymphoma at increased risk of relapse or progression following ASCT, (4) for the treatment of adult patients with CD30-positive cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy, (5) for the treatment of adult patients with relapsed or refractory sALCL, and (6) for the treatment of adult patients with CD30-positive cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy.

ADCETRIS has received marketing authorization by regulatory authorities in 73 countries for relapsed or refractory Hodgkin lymphoma and sALCL. See U.S. important safety information, including Boxed Warning, below.

Seattle Genetics and Takeda are jointly developing ADCETRIS. Under the terms of the collaboration agreement, Seattle Genetics has U.S. and Canadian commercialization rights and Takeda has rights to commercialize ADCETRIS in the rest of the world. Seattle Genetics and Takeda are funding joint development costs for ADCETRIS on a 50:50 basis, except in Japan where Takeda is solely responsible for development costs.

INOVIO’s INO-5401 in Combination with PD-1 Inhibitor Libtayo® (cemiplimab) Demonstrates 85% of Newly Diagnosed Glioblastoma Patients Are Alive 12 Months Following Treatment

On May 14, 2020 INOVIO (NASDAQ: INO) reported that 85 percent (44 out of 52) of patients newly diagnosed with the deadly brain cancer glioblastoma multiforme (GBM) who received the company’s DNA medicine INO-5401, in combination with INO-9012 and PD-1 inhibitor Libtayo (cemiplimab), were alive for at least 12 months or more (overall survival at 12 months: OS12) following treatment (Press release, Inovio, MAY 14, 2020, View Source [SID1234558053]). These data will be featured at an oral poster presentation at the ASCO (Free ASCO Whitepaper) 2020 Virtual Scientific Program, May 29-31, 2020.

GBM is the most common and aggressive type of brain cancer. Currently, the median overall survival with standard of care therapy, which includes radiation and chemotherapy (temozolomide: TMZ), is approximately 15 to 22 months.

The Phase 1/2 clinical trial demonstrated that 84.4% percent (27 of 32) of patients with MGMT promoter unmethylated tumors, and 85% (17 of 20) of patients with MGMT promoter methylated tumors were alive at 12 months. This promising clinical result is coupled with a robust immunological response to all three cancer antigens in INO-5401, including human telomerase (hTERT), Wilms Tumor-1 (WT-1) and prostate specific membrane antigen (PSMA). Activated, cytotoxic T cells directed towards these cancer antigens commonly expressed on GBM tumors were detected in all patients tested to date and continue to support the immunogenic potential of INOVIO’s DNA medicines. Importantly, INO-5401 + INO-9012 was safe and well-tolerated when given not only with radiation and TMZ, but also with PD-1 inhibition with Libtayo, which is being jointly developed by Regeneron and Sanofi. These results are being presented in a virtual format at the 2020 Annual ASCO (Free ASCO Whitepaper) meeting (Abstract #2514).

Dr. David Reardon, Clinical Director, Center for Neuro-Oncology of Dana-Farber Cancer Institute and coordinating principal investigator of GBM-001 said, "Although these data are preliminary, and follow-up remains early, this novel combination of a cancer antigen-specific, T cell generating DNA medicine with a PD-1 inhibitor is exciting and may overcome more than 20 years of a standard of care that has proven sub-optimal for our patients with GBM. A tolerable, new combination of medicines utilizing a novel mechanism of action, such as that provided by INO-5401 and INO-9012 with cemiplimab, is very welcome for this hard-to-treat brain cancer, especially when shown to be tolerable with standards such as radiation and chemotherapy, and when demonstrating the immunogenicity seen in the GBM-001 study."

Dr. J. Joseph Kim, INOVIO’s President & CEO, said, "While we recognize these data are early, we are very excited to see robust immunogenicity and the potential for extending survival, coupled with a clear ability to be able to combine not only with the standard of care, but with a checkpoint inhibitor, Libtayo. Where others have failed with single-agent checkpoint inhibition in GBM, our DNA medicine combined with Libtayo and standard of care has demonstrated clear immunogenicity and the potential to extend overall survival."

In a previous announcement, INOVIO reported key interim data from the 52-patient clinical trial showed that 80% (16 of 20) of MGMT gene promoter methylated patients and 75% (24 of 32) unmethylated patients were progression-free at six months (PFS6) measured from the time of their first dose, exceeding historical standard-of-care data.

This immunotherapy combination with a PD-1 checkpoint inhibitor also exhibited supportive safety, tolerability, and immunogenicity data and suggested an acceptable safety profile consistent with that of Libtayo and INOVIO’s platform technology. The majority of patients tested had a T cell immune response to one or more tumor-associated antigens encoded by INO-5401. Immune responses to all three tumor-associated antigens were demonstrated in this study. INOVIO plans to report 18-month overall survival data later this year.

Study Design

The trial was designed to evaluate safety, immunogenicity and preliminary efficacy of INO-5401 and INO-9012 in combination with Libtayo, with radiation and chemotherapy, in subjects with newly-diagnosed glioblastoma (GBM). This is a Phase 1/2, open-label, multi-center trial conducted in 52 evaluable patients with GBM. There are two cohorts in this trial. Cohort A includes 32 participants with a tumor with an unmethylated O6-methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT) promoter. Cohort B includes 20 participants with a tumor with a MGMT methylated promoter. Both cohorts received INO-5401 and INO-9012 and Libtayo at the same doses and on the same dosing schedule, and both cohorts received radiation and temozolomide (TMZ). Interim data presented here and at SITC (Free SITC Whitepaper) was obtained as of October 2019 and overall survival data at 18 months is expected in Q4 2020. For more information of the clinical study, see www.clinicaltrials.gov, identifier NCT03491683.

About Glioblastoma Multiforme (GBM)

GBM is the most common and aggressive type of brain cancer and remains a devastating disease for both patients and caregivers. Its prognosis is extremely poor, despite a limited number of new therapies approved over the last 10 years. The median overall survival for patients receiving standard of care therapy is approximately 15 to 22 months and the median progression-free survival is approximately 7 months. In the U.S., the estimated annual incidence of GBM is 11,362 cases or 3.21 cases per 100,000 persons and the median age at diagnosis is 65 years.

About INO-5401 and INO-9012

INO-5401 encodes for INOVIO’s SynCon antigens for hTERT, WT1, and PSMA, and has the potential to be a powerful cancer immunotherapy in combination with checkpoint inhibitors. The National Cancer Institute previously highlighted hTERT, WT1, and PSMA among a list of important cancer antigens, designating them as high priorities for cancer immunotherapy development. These three antigens were reported to be over-expressed, and often mutated, in a variety of human cancers, and targeting these antigens may prove efficacious in the treatment of patients with cancer. INO-9012 encodes for IL-12, which is a T cell immune activator.

About INOVIO’s DNA Medicines Platform

INOVIO has 15 DNA medicine clinical programs currently in development focused on HPV-associated diseases, cancer, and infectious diseases, including coronaviruses associated with MERS and COVID-19 diseases being developed under grants from the Coalition for Epidemic Preparedness Innovations (CEPI). DNA medicines are composed of optimized DNA plasmids, which are small circles of double-stranded DNA that are synthesized or reorganized by a computer sequencing technology and designed to produce a specific immune response in the body.

INOVIO’s DNA medicines deliver optimized plasmids directly into cells intramuscularly or intradermally using INOVIO’s proprietary hand-held smart device called CELLECTRA. The CELLECTRA device uses a brief electrical pulse to reversibly open small pores in the cell to allow the plasmids to enter, overcoming a key limitation of other DNA and other nucleic acid approaches, such as mRNA. Once inside the cell, the DNA plasmids enable the cell to produce the targeted antigen. The antigen is processed naturally in the cell and triggers the desired T cell and antibody-mediated immune responses. Administration with the CELLECTRA device ensures that the DNA medicine is efficiently delivered directly into the body’s cells, where it can go to work to drive an immune response. INOVIO’s DNA medicines do not interfere with or change in any way an individual’s own DNA. The advantages of INOVIO’s DNA medicine platform are how fast DNA medicines can be designed and manufactured, the stability of the products which do not require freezing in storage and transport, and the robust immune response, safety profile, and tolerability that have been demonstrated in clinical trials.

With more than 2,000 patients receiving INOVIO investigational DNA medicines in more than 6,000 applications across a range of clinical trials, INOVIO has a strong track record of rapidly generating DNA medicine candidates with potential to meet urgent global health needs.

"Over the last several months, the COVID-19 global pandemic has presented an unprecedented challenge, and as we face uncertainty in the coming months, we are grateful to have strong fundamentals across our business and the ability to fund our deep antibody pipeline. I am most grateful, however, for the continued support of our employees who have demonstrated exceptional focus and an unwavering dedication to our mission of developing therapies for the treatment of severe autoimmune diseases and cancer. This commitment is underscored by our decision to evaluate the potential of ARGX-117 to attenuate complement activation in severe respiratory illness associated with COVID-19 while obtaining key metrics of our drug candidate in this first-in-human trial."

FIRST QUARTER 2020 AND RECENT HIGHLIGHTS

argenx commitment to its people, patients and business
Despite the challenges of the COVID-19 pandemic, argenx remains focused on executing on its "argenx 2021" vision to become a fully integrated, global immunology company. In order to minimize impact on employees, patients and their communities, physicians and ongoing business priorities, argenx has implemented measures across its organization and in the operation of its globally run clinical trials.

A work-from-home mandate continues for all employees in the U.S., Belgium and Japan, excluding those providing essential services such as laboratory staff; additionally, all work-related global and domestic travel are suspended.
In order to enable patients in its clinical trials to receive study drug with continuity, argenx is implementing telehealth, remote monitoring activities and more flexible dosing schedules in its protocols where possible.
argenx conducts clinical trials globally, including in areas impacted by COVID-19 in North America, Europe and Japan. Enrollment is expected to be delayed in ongoing trials conducted by argenx, but the extent of the full impact is not quantifiable until the trajectory of the pandemic is better understood. The Company will continue to monitor the impact of COVID-19 on all ongoing clinical trials and will implement changes as necessary.

argenx continues to expand its early-stage pipeline

Cash, cash equivalents and current financial assets totaled €1,305.5 million on March 31, 2020, compared to €1,335.8 million on December 31, 2019 and €961.6 million on March 31, 2019.

Operating income amounted to €23.4 million for the three months ended March 31, 2020, compared to €40.0 million for the three months ended March 31, 2019. The decrease in the first three months of 2020 was primarily explained by the revenue recognized in the first quarter of 2019, following a $30.0 million development milestone payment received under the AbbVie collaboration agreement.

Research and development expenses increased by €60.1 million during the three months ended March 31, 2020 to reach €94.9 million, compared to €34.8 million for the three months ended March 31, 2019. This planned increase was mainly the result of (i) increased external research and development expenses reflecting higher clinical trial costs and manufacturing expenses related to the development of the argenx product candidate portfolio and (ii) higher personnel expenses as a result of increased costs of the share-based payment compensation plans related to the grant of stock options to argenx research and development employees and increased costs associated with additional research and development employees.

Selling, general and administrative expenses totaled €25.0 million and €11.3 million for the three months ended March 31, 2020 and 2019, respectively. The increase of €13.7 million was principally linked to an increase of personnel expense, resulting from (i) higher costs of the share-based payment compensation plans related to the grant of stock options to its selling, general and administrative employees and (ii) increased costs associated with additional employees recruited to strengthen its selling, general and administrative activities, notably in preparation of the potential commercial launch of efgartigimod in the U.S., if approved.

For the three months ended March 31, 2020, financial income, which primarily relate to interests received on its cash and cash equivalents and current financial assets, amounted to €1.7 million compared to €3.5 million for the same period in 2019. Financial expense amounted to €5.0 million for the three months ended March 31, 2020 and corresponded mainly to a decrease in net asset value on its current financial assets following the impact of the COVID-19 outbreak on the financial markets.

Exchange gains totaled €20.8 million for the three months ended March 31, 2020 compared to €9.5 million for the three months ended March 31, 2019 and were mainly attributable to unrealized exchange rate gains on cash, cash equivalents and current financial assets position in U.S. dollars due to the favorable fluctuation of the EUR/USD exchange rate.

The total comprehensive loss for the three months ended March 31, 2020 was €80.0 million compared to a total comprehensive profit, which was principally due to the milestone payment received from AbbVie as indicated above, of €6.7 million for the three months ended March 31, 2019.
