"Vyxeos is the first chemotherapy to demonstrate an overall survival advantage versus the standard of care in a Phase 3 study of older adult patients with newly diagnosed therapy- related AML or AML with myelodysplasia-related changes," said Daniel Swisher, president and chief operating officer at Jazz Pharmaceuticals. "Jazz is committed to making Vyxeos available to patients in the EU and we will now pursue rolling launches of Vyxeos across the European Union on a country-by-country basis as pricing and reimbursement decisions are made."

The European Commission approval extends to all European Union Member States, as well as Iceland, Norway and Liechtenstein.

"AML is a rare cancer in Europe and patients with therapy-related AML or AML with myelodysplasia-related changes have a particularly poor prognosis compared to people with other forms of leukaemia," said Professor Charles Craddock CBE, Academic Director, Centre for Clinical Haematology at University Hospitals Birmingham NHS Foundation Trust. "Vyxeos is a new and clinically meaningful treatment option that provides a welcome advance for patients and health care professionals across the European Union."

The Marketing Authorisation Application (MAA) for Vyxeos included clinical data from five studies, including the pivotal Phase 3 study. Data from the Phase 3 study was published in the Journal of Clinical Oncology in July 2018. The study evaluated the efficacy and safety of Vyxeos compared to 7+3 chemotherapy in 309 patients 60 to 75 years of age with newly diagnosed t-AML or AML-MRC, a rapidly progressing and life-threatening blood cancer.

The study met its primary endpoint as Vyxeos demonstrated a superior improvement in overall survival compared to the 7+3 treatment regimen. The median overall survival for the Vyxeos treatment group was 9.6 months compared with 5.9 months for the 7+3 treatment group (2-sided p-value = 0.005; HR [95% confidence interval] = 0.69 [0.52, 0.90]). Vyxeos was also associated with a significantly higher remission rate than 7+3 with a complete response rate of 37% versus 26%; p=0.036. In addition, the overall rate of hematopoietic stem cell transplant (HSCT) was 34% in the Vyxeos arm and 25% in the 7+3 arm. The reported adverse reactions with Vyxeos were generally consistent with the known safety profile of cytarabine and daunorubicin therapy.

The incidences of non-haematologic adverse events were comparable between arms, despite a longer treatment phase and prolonged time to neutrophil and platelet count recovery with Vyxeos. Fatal treatment-emergent CNS hemorrhage not in the setting of progressive disease occurred in 2% of patients in the Vyxeos arm and 0.7% of patients in the control arm. Six percent of patients in both the Vyxeos and control arm had a fatal adverse reaction on treatment or within 30 days of therapy that was not in the setting of progressive disease. The most common adverse reactions (incidence ≥ 25%) were bleeding events, fever, rash, swelling, nausea, sores in the mouth or throat, diarrhea, constipation, muscle pain, tiredness, stomach pain, difficulty breathing, headache, cough, decreased appetite, irregular heartbeat, pneumonia, blood infection, chills, sleep disorders and vomiting.

About Vyxeos
Vyxeos 44 mg/100 mg powder for concentrate for solution for infusion is an advanced liposomal formulation that delivers a synergistic combination of daunorubicin and cytarabine to leukaemia cells for a prolonged period of time. Based on data in animals, Vyxeos liposomes accumulate and persist in high concentration in the bone marrow, where they are preferentially taken up intact by leukaemia cells. Vyxeos is the first product developed with the company’s proprietary CombiPlex platform, which enables the design and rapid evaluation of various combinations of therapies. Vyxeos received Orphan Drug Designation (ODD) by the European Commission in January 2012 with retention of the ODD reaffirmed in July 2018 following assessment by the Committee for Orphan Medicinal Products (COMP) and by the U.S. Food and Drug Administration (FDA) in September 2008 for the treatment of AML. Vyxeos received Promising Innovative Medicine (PIM) designation from the Medicines and Healthcare Products Regulatory Agency in the United Kingdom. The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion in June 2018 recommending marketing authorisation for Vyxeos. Vyxeos received U.S. FDA approval and orphan drug exclusivity in August 2017.

About CombiPlex
The CombiPlex proprietary technology enables the design and rapid evaluation of various combinations of therapies to deliver enhanced anti-cancer activity. The CombiPlex technology seeks to identify the most synergistic ratio of drugs in vitro and fix this ratio in a nano-scale delivery complex that maintains the synergistic combination after administration. CombiPlex utilizes two proprietary nano-scale delivery platforms: liposomes to control the release and distribution of water-soluble drugs and drugs that are both water- and fat-soluble (amphipathic), and nanoparticles to control the release and distribution of non-water-soluble (hydrophobic) drugs.

About AML
Acute myeloid leukaemia (AML) is a blood cancer that begins in the bone marrow, which produces most of the body’s new blood cells. AML cells crowd out healthy cells and move into the bloodstream to spread cancer to other parts of the body. 1 The median age at diagnosis is 68 years old, with rising age associated with a progressively worsening prognosis.2-3 There is also a reduced tolerance for intensive chemotherapy as patients age.4 Patients with t-AML or AML-MRC have few treatment options and some of the lowest survival rates compared to people with other forms of leukaemia.5-6 A hematopoietic stem cell transplant (HSCT) may be a curative treatment option for patients.7

"We are very pleased to obtain our third China IND approval of our investigational drugs in 2018. CStone already initiated CS1002’s Phase I clinical trial in Australia and dosed the first patient in May." said Dr. Frank Jiang, Chairman and Chief Executive Officer of CStone. " With today’s IND approval of CS1002, CStone is currently the only biopharmaceutical company in China that has all three immuno-oncology ‘backbone’ products (anti-PD-L1, anti-PD-1, and anti-CTLA-4 mAbs) in the clinical stage."

"CS1002 has demonstrated a high level of selectivity, specificity and high affinity to CTLA-4 in preclinical studies," said Dr. Jingrong Li, Senior Vice President of Product Development and Manufacture at CStone. "Combination therapies of anti-CTLA-4 mAb with anti-PD-1 mAb have demonstrated promising efficacy in multiple tumor types by global clinical trials. CStone will explore combination potentials between CS1002 and other drug candidates in our pipeline to provide better therapies for cancer patients in China and beyond."

As of today, CStone has built a portfolio of 14 oncology products, 8 of which are at clinical development stage, including 3 in registration studies. CS1001, China’s first fully human, full-length anti-PD-L1 mAb developed by CStone, has entered pivotal Phase II clinical studies, and will potentially become one of the first locally-developed anti-PD-L1 cancer drugs launched in China. In June 2018, CStone announced the exclusive collaboration and license agreements with Blueprint Medicine and Agios Pharmaceuticals. With these two deals, CStone in-licensed 4 post proof of concept assets, including ivosidenib, which is recently approved by U.S. FDA for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (R/R AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation, and avapritinib, which has entered global Phase III clinical studies.

About the CTLA-4 pathway

Cytotoxic T lymphocyte associated antigen 4 (CTLA-4), also known as CD152, is a transmembrane protein encoded by the CTLA-4 gene that can down-regulate the activity of T cells when binding with its ligands, B7.1 and B7.2, a pathway also used by tumor cells to avoid T lymphocyte attack. Consequently, blockade of the CTLA-4 pathway can stimulate T cell activation and proliferation to induce or enhance anti-tumor immune responses. CTLA-4 provides a new immuno-therapeutic approach to a number of diseases, including tumors.

Presently, Bristol-Myers Squibb’s Yervoy (ipilimumab) is the only anti-CTLA-4 antibody to gain a market approval worldwide, although Yervoy has not yet been approved in China. Pre-clinical tests have shown that CS1002 has a relatively strong affinity to CTLA-4 and is expected to match Yervoy in terms of efficacy.
