Novartis receives positive CHMP opinion for Kymriah® for treating two aggressive blood cancers, marking important medical advance for patients in Europe

On June 29, 2018 Novartis reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending approval of Kymriah (tisagenlecleucel, formerly CTL019) – a novel one-time treatment that uses a patient’s own T cells to fight cancer (Press release, Novartis, JUN 29, 2018, View Source [SID1234527508]). The positive opinion includes two B-cell malignancies: B-cell acute lymphoblastic leukemia (ALL) that is refractory, in relapse post-transplant or in second or later relapse in patients up to 25 years of age; and diffuse large B-cell lymphoma (DLBCL) that is relapsed or refractory (r/r) after two or more lines of systemic therapy in adults.

"The positive CHMP opinion for Kymriah is a watershed moment for pediatric and adult patients in Europe with aggressive blood cancers," said Liz Barrett, CEO, Novartis Oncology. "This truly transformative therapy helps address a profound unmet need, and Novartis is proud that our leadership in CAR-T innovation will make a meaningful difference to patients in the EU."

If approved by the European Commission, Kymriah will be the first CAR-T cell therapy available in the European Union (EU) for both DLBCL and B-cell ALL.

Both B-cell ALL and DLBCL are aggressive malignancies with significant treatment gaps for patients. In Europe, ALL accounts for approximately 80% of leukemia cases among children[1], and for those patients who relapse, the outlook is poor[2]. This low survival rate is in spite of patients having to undergo multiple treatments, including chemotherapy, radiation, targeted therapy or stem cell transplant, and further highlights the need for new treatment options. DLBCL is the most common form of non-Hodgkin lymphoma, accounting for up to 40% of all cases globally[3]. For patients who relapse or don’t respond to initial therapy, there are limited treatment options that provide durable responses, and survival rates are low for the majority of patients due to ineligibility for autologous stem cell transplant (ASCT) or because salvage chemotherapy or ASCT have failed[4].

The positive CHMP opinion is based on two pivotal Novartis-sponsored global, multi-center, Phase II trials, ELIANA and JULIET, which included patients from Europe, the US, Australia, Canada and Japan.

The collaboration of Novartis and the University of Pennsylvania has led to historic milestones in CAR-T cell therapy since 2012, including the initiation of the first global CAR-T trials, the PRIME designation granted by the EMA for Kymriah in pediatric patients with r/r B-cell ALL, and the approval of Kymriah in two distinct indications by the US Food and Drug Administration (FDA).

"Kymriah is already transforming the way we treat certain types of leukemia and lymphoma in the United States, and showing us that personalized cell therapies are an incredibly powerful tool in the fight against cancer," said Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine and director of the Center for Cellular Immunotherapies in the Abramson Cancer Center. "We are excited to see that through our collaboration with Novartis, physicians in more countries around the world may be able to use this novel and innovative CAR-T cell therapy to improve the treatment outcomes for their patients."

ELIANA is the first pediatric global CAR-T cell therapy registration trial, treating patients in 25 centers in the US, Canada, Australia, Japan and the EU, including: Austria, Belgium, France, Germany, Italy, Norway and Spain. JULIET is the first multi-center global registration study for Kymriah in adult patients with r/r DLBCL.

JULIET is also the largest global study evaluating a CAR-T cell therapy in patients with DLBCL, enrolling patients from 27 sites in 10 countries across the US, Canada, Australia, Japan and the EU, including: Austria, France, Germany, Italy, Norway and the Netherlands.

The Novartis CAR-T cell manufacturing platform includes cryopreservation, the process of freezing patients’ harvested cells in order to preserve them, which provides physicians with the flexibility to decide when to initiate both the harvesting of patients’ cells and the infusion of Kymriah, based on each patient’s condition, and allows for this individualized treatment approach on a global scale.

"Today’s positive opinion from the CHMP marks a truly extraordinary moment for those who have been impacted by these types of advanced and aggressive B-cell malignancies," said Dr. Ulrich Jäger, Professor of Hematology at the Medical University of Vienna and Head of Hematology at the General Hospital of the City of Vienna. "European patients and doctors have been anxiously awaiting the introduction of Kymriah, which will bring a significant advancement in the treatment landscape for these patients who face a poor prognosis."

The European Commission will now review the CHMP recommendation to deliver its final decision, applicable to all 28 EU member states, plus Iceland, Liechtenstein and Norway.

"This CHMP decision brings an innovative option closer to European patients who have exhausted most alternative treatments," said Zack Pemberton-Whiteley, Chair of the Global Acute Leukemia Advocates Network and Campaigns and Advocacy Director at Leukaemia Care. "It’s important to note that CAR-T therapy may be suitable for a limited group of patients. Working with healthcare professionals to ensure safe and timely access for those who need it will be of paramount importance."

Additional regulatory filings are under review for Kymriah in Canada, Switzerland, Australia and Japan.

About CAR-T
CAR-T is different from typical small molecule or biologic therapies because it is manufactured for each individual patient using their own cells. During the treatment process, T cells are drawn from a patient’s blood and reprogrammed in the laboratory to create T cells that are genetically coded to recognize and fight the patient’s cancer cells and other B cells expressing a particular antigen.

Novartis Leadership in Immuno-Oncology
Novartis is at the forefront of investigational immunocellular therapy as the first pharmaceutical company to initiate global CAR-T trials, and has significantly invested in CAR-T research and worked with pioneers in the field. Kymriah, the first approved CAR-T cell therapy, is the cornerstone of this strategy. Active research programs are underway targeting other hematologic malignancies and solid tumors, and include efforts focused on next generation CAR-Ts with evolved manufacturing schemes and gene edited cells.

Kymriah (tisagenlecleucel, formerly CTL019) Important Safety Information from the US Prescribing Information
Kymriah is currently only approved in the United States.

Kymriah is made from your own white blood cells and is a prescription cancer treatment used in patients up to 25 years old who have acute lymphoblastic leukemia (ALL) that is either relapsing (went into remission, then came back) or refractory (did not go into remission after receiving other leukemia treatments). It is also used in patients with certain forms of large B-cell lymphoma that have relapsed or are refractory after having at least two other kinds of treatment.

Kymriah may cause side effects that are severe or life threatening, such as Cytokine Release Syndrome (CRS) or Neurological Toxicities. Patients with CRS may experience symptoms including difficulty breathing, fever (100.4’F/38’C or higher), chills/shaking chills, severe nausea, vomiting and diarrhea, severe muscle or joint pain, very low blood pressure, or dizziness/lightheadedness. Patients may be admitted to the hospital for CRS and treated with other medications.

Patients with neurological toxicities may experience symptoms such as altered or decreased consciousness, headaches, delirium, confusion, agitation, anxiety, seizures, difficulty speaking and understanding, or loss of balance. Patients should be advised to call their healthcare provider or get emergency help right away if they experience any of these signs and symptoms of CRS or neurological toxicities.

Because of the risk of CRS and neurological toxicities, Kymriah is only available through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called Kymriah REMS.

Serious allergic reactions, including anaphylaxis, may occur after Kymriah infusion.
Kymriah can increase the risk of life-threatening infections that may lead to death. Patients should be advised to tell their healthcare provider right away if they develop fever, chills, or any signs or symptoms of an infection.

Patients may experience prolonged low blood cell counts (cytopenia), where one or more types of blood cells (red blood cells, white blood cells, or platelets) are decreased. The patient’s healthcare provider will do blood tests to check all of their blood cell counts after treatment with Kymriah. Patients should be advised to tell their healthcare provider right away if they get a fever, are feeling tired, or have bruising or bleeding.

Patients may experience hypogammaglobulinemia, a condition in which the level of immunoglobulins (antibodies) in the blood is low and the risk of infection is increased. It is expected that patients may develop hypogammaglobulinemia with Kymriah, and may need to receive immunoglobulin replacement for an indefinite amount of time following treatment with Kymriah. Patients should tell their healthcare provider about their treatment with Kymriah before receiving a live virus vaccine.

After treatment with Kymriah, patients will be monitored lifelong by their healthcare provider, as they may develop secondary cancers or recurrence of their cancer.

Patients should not drive, operate heavy machinery, or do other dangerous activities for eight weeks after receiving Kymriah because the treatment can cause temporary memory and coordination problems, including sleepiness, confusion, weakness, dizziness, and seizures.

Some of the most common side effects of Kymriah are difficulty breathing, fever (100.4°F/38°C or higher), chills/shaking chills, confusion, severe nausea, vomiting and diarrhea, severe muscle or joint pain, very low blood pressure, dizziness/lightheadedness, and headache. However, these are not all of the possible side effects of Kymriah. Patients should talk to their healthcare provider for medical advice about side effects.

Prior to a female patient starting treatment with Kymriah, their healthcare provider may do a pregnancy test. There is no information available for Kymriah use in pregnant or breast-feeding women. Therefore, Kymriah is not recommended for women who are pregnant or breast feeding. Patients should talk to their healthcare provider about birth control and pregnancy.

Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

After receiving Kymriah, patients should be advised that some commercial HIV tests may cause a false-positive test result. Patients should also be advised not to donate blood, organs, or tissues and cells for transplantation after receiving Kymriah.

Kymab and Roche clinical trial agreement for KY1044

On June 28, 2018 Kymab reported its clinical trial agreement with F. Hoffmann-La Roche Ltd under which Roche will provide its PD-L1 blocking antibody atezolizumab for use in combination with Kymab’s lead investigational anti-ICOS antibody therapy KY1044 in Kymab’s upcoming Phase I/II clinical studies in patients with advanced solid cancers (Press release, Kymab, JUN 28, 2018, View Source [SID1234537005]).

"We have presented preclinical data demonstrating strong synergies between an anti-PD-L1 treatment in combination with KY1044 against multiple tumour types," says Arndt Schottelius, MD, PhD, Executive Vice President, Research and Development of Kymab. "We look forward to the initiation of our first studies and exploration of the potential synergy of our programs for the benefit of patients with advanced solid cancers."

Kymab will be responsible for conducting the clinical trials, and both companies will share data from the trials. Kymab continues to retain all commercial rights to KY1044.

KY1044 is designed to both deplete intratumoral Regulatory T-cells and stimulate T Effector cells to enhance the immune response against tumors.

Kymab plans to conduct a Phase I/II study in a variety of solid tumours both as monotherapy and in combination with atezolizumab. Indications that have elevated levels of both ICOS and FOXP3 might be especially responsive to this combination of checkpoint inhibitors.

Kymab will lead studies to evaluate this hypothesis: atezolizumab, an anti-PD-L1 antibody that acts as a checkpoint inhibitor, and KY1044, an antibody targeting ICOS expression, will be tested for synergistic action to recalibrate the immune response. Kymab plans to initiate monotherapy studies of KY1044 in the first half of 2019 and studies in combination with TECENTRIQ in the second half.

TECENTRIQ (atezolizumab) is a registered trademark of Genentech, a member of the Roche Group.

About KY1044
KY1044 is a fully human monoclonal antibody discovered by Kymab’s unique suite of technologies. KY1044 has now been tested in number of highly illustrative syngeneic models, which demonstrate that KY1044 strongly inhibits tumor growth in cancers both as a monotherapy and in combination with other immunotherapies.

Inducible T Cell Co Stimulator (ICOS), is expressed upon activation on T cells and at high levels on the majority of FOXP3+ regulatory CD4+ T cells. Importantly, available data demonstrate that depletion of these immunosuppressive cells from the tumor microenvironment enhances the patient’s anti-tumor immune response.

Actinium Announces New Clinical Trial to Study Effect of Actimab-A on Minimal Residual Disease in Postremission AML Patients

On June 28, 2018 Actinium Pharmaceuticals, Inc. (NYSE AMERICAN:ATNM) ("Actinium" or "the Company"), reported that Dr. Joseph Jurcic, Director of the Hematologic Malignancies Section and Professor of Medicine at Columbia University Medical Center, has initiated Actimab-A MRD, a new clinical trial for patients with AML who are in remission but have detectable minimal residual disease (MRD) (Press release, Actinium Pharmaceuticals, JUN 28, 2018, View Source [SID1234527514]). The trial will study the safety/tolerability of Actimab-A in the postremission consolidation setting and include dose finding analyses. The trial will also study the impact of Actimab-A on minimal residual disease (MRD) as well as progression-free (PFS) and overall survival (OS) rates. The investigational new drug (IND) application for this trial has been cleared by the FDA.

Together with Dr. Jurcic, Actinium will host a webcast to discuss the planned trial, participation information is as follows:

Dr. Joseph Jurcic said, "Although patients with AML can achieve complete remissions with induction therapy, the rate of relapse remains high resulting in high mortality rates. Strong evidence exists that minimal residual disease is a major driver of disease relapse and clearly demonstrates the need for improved consolidation therapies that can effectively target MRD. Based on the clinical profile of Actimab-A to date, I am excited to study this therapy for use as a consolidation therapy. It will be a significant advancement for AML patients if this trial shows the ability to target MRD and reduce relapse rates."

There are an estimated 21,000 patients diagnosed with AML annually in the United States and over 350,000 cases of AML worldwide. According to the National Cancer Institute, 5-year survival for AML patients under age 65 is 45% while 5-year survival for patients over 65 is 6% with the median age of diagnosis of AML patients being 68. With curative intent induction chemotherapy, 45% – 65% of patients can achieve complete remission but up to 80% of patients will relapse despite postremission consolidation treatment. Currently, non-transplant-based consolidation therapies consist mainly of chemotherapy such as high-dose Cytarabine. The presence of MRD has been shown to be associated with higher rates of relapse and earlier relapse in multiple studies. Recently, the FDA approved a therapy for patients with a certain type of B-cell leukemia who are in remission but have detectable MRD.

Dr. Mark Berger, Actinium’s Chief Medical Officer said, "Actimab-A has many points of differentiation that I feel make it well suited to address MRD treatment as consolidation therapy. Given that patients receive chemotherapy as induction therapy, I believe it is important to develop a non-chemotherapy based consolidation therapy that has fewer toxicities and side effects than chemotherapy. This is particularly important for older patients, who do not have the same ability to tolerate high dose therapies as young patients, and who are the majority of patients with AML. We believe our ARC or Antibody Radiation Conjugate approach enables precision targeting of residual AML cells and potentially provide a means by which MRD can be eliminated and relapse rates lowered. We look forward to working with Dr. Jurcic to execute this important trial for AML patients."

Sandesh Seth, Actinium’s Chairman and CEO said, "We are excited by the continued expansion of our CD33 program and intend to solidify our position as the best-in-class CD33 targeting therapy by demonstrating its potential in multiple diseases and multiple indications. Expansion into the consolidation setting is an important achievement towards this end. Further, the application of our therapy for MRD, strategically aligns us with the forefront of scientific exploration in a clinical setting. We believe the breadth of our CD33 program is unmatched given that we are now studying our ARC not only in multiple AML settings including induction, consolidation and in relapsed/refractory disease but also in multiple myeloma as a therapeutic, and in MDS as targeted conditioning to enable a bone marrow transplant. With this important trial poised to start and clinical data expected from our ongoing trials, we are confident in our ability to realize the intrinsic value of this program and advance these trials to benefit the greatest number of patients."

About Actimab-A
Actimab-A is an antibody radio-conjugate (ARC) comprised of the anti-CD33 monoclonal antibody lintuzumab labeled with the radioisotope actinium-225. CD33 is a marker expressed on AML cells of virtually all affected patients. Actimab-A has been studied in over 100 patients to date and is the only CD33 targeting agent being studied in a broad range of diseases in which the CD33 antigen is expressed, including AML, myelodysplastic syndrome (MDS) and multiple myeloma.

Actinium-225 is highly differentiated radioisotope that emits high amounts of energy through the release of four alpha-particles that can cause double-stranded breaks in DNA with known resistance mechanisms to Actinium-225. Given the limited distance of its energy in the body, it is potentially sparing of non-targeted cells leading to better tolerability and less toxicities.

Actimab-A has been granted Orphan Drug Designation from both the U.S. Food and Drug Administration and the European Medicines Agency for newly diagnosed AML in patients age 60 and above.

MolMed and AbCheck sign a three-year Master Agreement for the development of new CARs targeting novel tumor antigens

On June 28, 2018 MolMed S.p.A. (MLMD.MI), a medical biotechnology company focusing on research, development, manufacturing, and clinical validation of cell & gene therapies to treat cancer and rare diseases and AbCheck s.r.o., a technology company focusing on the discovery and optimization of high-quality human antibodies, reported that they have entered into a three-year Master Agreement aimed at providing MolMed with selected and optimized antibodies for the development of new Chimeric Antigen Receptors (CARs), targeting both liquid and solid tumors (Press release, MolMed, JUN 28, 2018, View Source [SID1234527504]).

Under the agreement, AbCheck will use its proprietary discovery platform to select, optimize and deliver multiple human single-chain variable fragments (scFvs), specifically recognizing each MolMed target candidate. ScFvs are the extracellular regions of the CAR responsible for antigen recognition and binding, conferring specificity to the CAR.

The new and optimized scFvs delivered by AbCheck will allow MolMed to expand its proprietary pipeline in both autologous CAR-T and future allogenic CAR-NK platforms.

Riccardo Palmisano, MolMed CEO, commented: "This new collaboration plays a key role to complete the picture of the planned and announced enlargement of our CAR pipeline. Leveraging on the unique experience that we developed on CAR T CD44v6, now close to clinical stage in acute myeloid leukemia and multiple myeloma and on the recently signed partnership with Glycostem, with this agreement with AbCheck, a company with extensive expertise in antibodies selection and boasting partnerships with relevant companies and institutions in the CAR field, MolMed is fully prepared to build a robust autologous and allogeneic original CAR T pipeline, able to target both liquid and solid tumors".

Volker Lang, Managing Director of AbCheck, added: "AbCheck is recognized for its proven capability to reliably deliver high-quality human antibodies suitable for clinical development. We are very pleased to employ our unique technology suite to support MolMed’s dedicated team in adding novel therapeutic options to its diverse pipeline. Both CAR-Ts and CAR-NKs represent promising novel immuno-oncology approaches and we are confident that AbCheck’s abilities in antibody discovery and optimization will be an important asset in developing such approaches."

BIOATLA ANNOUNCES FIRST PATIENT TREATED IN PHASE1/2 BA3021-001 CLINICAL TRIAL FOR CAB-ROR2-ADC THERAPEUTIC

On June 28, 2018 BioAtla, LLC, a global biotechnology company focused on the development of Conditionally Active Biologic (CAB) protein therapeutics, reported the treatment of the first patient in its clinical trial BA3021-001 for BioAtla’s BA3021, a novel conditionally active ROR2-targeted antibody-drug conjugate (CAB-ROR2-ADC) (Press release, BioAtla, JUN 28, 2018, View Source [SID1234527502]). This is a multi-center, open-label, Phase 1/2 study designed to evaluate the safety, tolerability, pharmacokinetics, immunogenicity and antitumor activity of BA3021 in patients with advanced solid tumors including non-small cell lung cancer (NSCLC), triple negative breast cancer and soft tissue sarcoma. CAB-ROR2-ADC is BioAtla’s second CAB investigational product to enter clinical trials following BA3011, CAB-AXL-ADC in February of this year.

The first patient in the BA3021 clinical study was enrolled and dosed at Sarah Cannon Research Institute at Tennessee Oncology in Nashville, TN under the direction of the principal investigator, Howard A. "Skip" Burris III, MD. Dr. Burris, a recognized leader in clinical oncology, serves as chief medical officer and president of clinical operations at Sarah Cannon. "Innovative advancements in the treatment of cancer include tumor specific activation of therapy and promoting appropriate immune response. Providing access to cutting-edge therapies in clinical trials, such as the BA3021 clinical study, further supports our mission to advance care for cancer patients," said Dr. Burris.

The ROR2 transmembrane protein tyrosine kinase is an onco-fetal protein that acts as a non-canonical Wnt 5A receptor. ROR2 is found to be highly expressed during embryonic development and in several important cancer types, and the level of expression in tumors is tightly correlated with patient prognosis. Recently, ROR2 and its ligand Wnt 5A have been shown to be induced in cancers that are resistant to treatment with immune checkpoint inhibitors such as anti-PD-1 antibody immune therapy suggesting a mechanistic role of this receptor-ligand axis in resistance to standard cancer treatments resulting in relapsing, minimal residual disease. However, low to moderate levels of expression of ROR2 in multiple normal adult tissues are predicted based on RNA expression, histological analysis and functional studies. To minimize the risk of potential disruption of normal function of ROR2 receptors on normal cells, BioAtla applies its proprietary CAB technology to develop its CAB antibody-drug conjugate (ADC) targeting ROR2 with the intent to activate binding to the ROR2 receptor only in the tumor microenvironment and deliver the toxic payload to the cancerous cells. The CAB-ROR2-ADC BA3021 is designed to maximize efficacy on ROR2 expressing tumors while minimizing toxicity, leading to better clinical outcomes.

About Conditionally Active Biologics (CABs)

Conditionally Active Biologic proteins are generated using BioAtla’s proprietary protein discovery, evolution and expression technologies. These proteins can be monoclonal antibodies, enzymes and other proteins designed with functions dependent on changes in microphysiological conditions (e.g., pH level, oxidation, temperature, pressure, presence of certain ions, hydrophobicity and combinations thereof) both outside and inside cells.

Studies have shown that cancerous tumors create highly specific conditions at their site that are not present in normal tissue. These cancerous microenvironments are primarily a result of the well understood unique glycolytic metabolism associated with cancer cells, referred to as the Warburg Effect. CAB proteins are designed to deliver their therapeutic payload and/or recruit the immune response in specific and selected locations and conditions within the body and to be active only in the presence of a particular cellular microenvironment. In addition, the activation is designed to be reversible to repeatedly switch ‘on and off’ should the CAB move from a diseased to a normal cellular microenvironment and vice versa. CABs can be developed in a variety of formats including antibodies, antibody drug conjugates (ADCs), bi-specifics, chimeric antigen receptor T-cells (CAR-Ts) and combination therapies.
