The CHMP’s opinion is now being referred to the European Commission (EC), for a final decision on the grant of a marketing authorisation. This decision is expected by the end of 2018 and will apply to all 28 countries of the European Union, Norway, Iceland and Liechtenstein.

"At Kyowa Kirin we are fully committed to contributing to the health and wellbeing of patients across Europe who are living with mycosis fungoides and Sézary syndrome," said Mitsuo Satoh, Ph.D., Executive Officer, Vice President Head of R&D Division of Kyowa Hakko Kirin. "I am happy about the CHMP’s opinion which takes us one step closer to obtaining an EU marketing authorisation, launching mogamulizumab and to leaping forward to becoming a global specialty pharmaceutical company."

"Mycosis fungoides (MF) and Sézary syndrome (SS) can be disfiguring, debilitating, and even life-threatening, and there are limited treatment options for these rare lymphoma subtypes in Europe today," said Jeffrey S. Humphrey, MD, President of Kyowa Kirin Pharmaceutical Development, Inc. "MAVORIC, the pivotal Phase 3 trial of mogamulizumab, is the largest study of systemic therapy ever conducted in MF and SS. The study showed that mogamulizumab prolonged progression-free survival compared to vorinostat in patients with MF or SS. We will continue to work with the scientific community to advance the understanding of these complex diseases, and we look forward to working with health authorities to bring this important new option to Europe."

If mogamulizumab is approved, Kyowa Kirin International PLC, a Kyowa Hakko Kirin Group company, will be responsible for commercializing mogamulizumab in Europe.

The Kyowa Hakko Kirin Group companies strive to contribute to the health and well-being of people around the world by creating new value through the pursuit of advances in life sciences and technologies.

Mogamulizumab Regulatory Status in EU
The EMA’s scientific committee, CHMP adopted a Positive Opinion recommending the approval of the marketing authorisation of mogamulizumab for the treatment of adult patients with mycosis fungoides (MF) or Sézary syndrome (SS) after at least one prior systemic therapy. The CHMP’s recommendation is now being referred to the European Commission (EC), which is expected to render its final decision by the end of 2018. The EC typically adheres to the recommendation of the CHMP, but is not obligated to do so.

Roche announces CHMP recommendation for EU approval of Venclyxto plus MabThera for people with previously treated chronic lymphocytic leukaemia

On September 21, 2018 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the EU Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Venclyxto (venetoclax) in combination with MabThera (rituximab) for the treatment of people with chronic lymphocytic leukaemia (CLL) who have received at least one prior therapy (Press release, Hoffmann-La Roche, SEP 21, 2018, View Source [SID1234529529]). In Europe, the incidence of all leukaemias is estimated to be almost 77,0001 and CLL, the most common type, accounts for approximately one-third of new leukaemia diagnoses.2

"CLL is incurable and becomes harder to treat each time it returns, especially in elderly patients who have other existing conditions," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We’re pleased that the CHMP has recognised the potential of Venclyxto plus MabThera to provide an important new chemotherapy-free option for people with previously treated CLL."

The CHMP’s recommendation is based on results from the randomised phase III MURANO study which showed that a fixed duration of treatment with Venclyxto plus MabThera significantly reduced the risk of disease progression or death (progression-free survival [PFS] as assessed by investigators [INV]; primary endpoint of the study) by 83% compared with bendamustine plus MabThera (BR), a current standard of care (HR=0.17; 95% CI 0.11-0.25; p<0.0001). PFS assessed by independent review committee was consistent. In addition, minimal residual disease (MRD)-negativity in peripheral blood at end of combination treatment was 62.4% with Venclyxto plus MabThera compared to 13.3% with BR. Being MRD-negative means no cancer can be detected in the blood and or bone marrow using a sensitive test. In Europe, MRD is used as an indicator of a patient achieving longer endpoints such as PFS and overall survival. The most commonly observed side effects of Venclyxto plus MabThera included low white blood cell count (neutropenia), diarrhoea and upper respiratory tract infection.

Based on this positive CHMP recommendation, a final decision regarding the approval of Venclyxto is expected from the European Commission in the near future. Additional submissions of the MURANO data to health authorities around the world are ongoing.

Venclyxto is being developed by AbbVie and Roche. It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the United States, under the brand name Venclexta, and commercialised by AbbVie outside of the United States.

About the MURANO Study
MURANO (NCT02005471) is a phase III open-label, international, multicentre, randomised study evaluating the efficacy and safety of fixed duration treatment Venclexta/Venclyxto (venetoclax) in combination with MabThera/Rituxan (rituximab) compared to standard of care bendamustine in combination with MabThera/Rituxan (BR) in patients with relapsed or refractory chronic lymphocytic leukaemia (CLL). Patients on the Venclexta/Venclyxto plus MabThera/Rituxan arm received six cycles of Venclexta/Venclyxto plus MabThera/Rituxan followed by Venclexta/Venclyxto monotherapy for up to two years total. Patients on the BR arm received six cycles of BR. The study included 389 patients with CLL who had been previously treated with at least one line of therapy. Patients were randomly assigned in a 1:1 ratio to receive either Venclexta/Venclyxto plus MabThera/Rituxan or BR. The primary endpoint of the study was progression-free survival (PFS) as assessed by investigator (INV). Secondary endpoints included overall survival (OS), overall response rate (ORR), complete response rate (with or without complete blood count recovery, CR/CRi), minimal residual disease (MRD) and safety.

The most common adverse reactions (≥20%) of any grade in patients receiving Venclyxto in the combination study with MabThera were neutropenia, diarrhoea, and upper respiratory tract infection. Death occurred in 11% of people who received Venclexta/Venclyxto plus MabThera/Rituxan compared to 16% for BR.

About Venclexta/Venclyxto
Venclexta/Venclyxto is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers and other tumours, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta/Venclyxto blocks the BCL-2 protein and works to restore the process of apoptosis.

Venclexta/Venclyxto is being developed by AbbVie and Roche. It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the United States and by AbbVie outside of the United States. Together, the companies are committed to research with Venclexta/Venclyxto, which is currently being studied in clinical trials across several types of blood and other cancers.

In the United States, Venclexta has been granted four Breakthrough Therapy Designations by the FDA: in combination with Rituxan for people with relapsed or refractory chronic lymphocytic leukaemia; as a monotherapy for people with relapsed or refractory CLL with 17p deletion; in combination with hypomethylating agents (azacitidine or decitabine) for people with untreated acute myeloid leukaemia (AML) ineligible for intensive chemotherapy; and in combination with low-dose cytarabine for people with untreated AML ineligible for intensive chemotherapy.

Venclexta/Venclyxto is approved in more than 50 countries. Roche and AbbVie are currently working with regulatory agencies around the world to bring this medicine to additional eligible patients in need.

About Chronic Lymphocytic Leukaemia
Chronic lymphocytic leukaemia (CLL) is the most common type of leukaemia in the Western world.2 CLL mainly affects men and the median age at diagnosis is about 70 years.3 In Europe, the incidence of all leukaemias is estimated to be almost 77,0001 and CLL is estimated to affect around one-third of all people newly diagnosed with leukaemia.2

AML is a cancer that impacts the blood and bone marrow, and its incidence increases with age. In Japan, approximately 5,500 patients are diagnosed with AML each year1. XOSPATA has demonstrated inhibitory activity against both internal tandem duplication (ITD) and tyrosine kinase domain (TKD), FLT3 mutations that are seen in approximately one-third of patients with AML.

This approval is based on the CR/CRh2 rate results from the interim analysis of the multinational Phase 3 ADMIRAL study. In October 2015, gilteritinib was designated as one of the first products in Japan to be included in the SAKIGAKE3 designation system. A similar application for approval was filed in the United States in March, 2018 and is currently under review.

With this approval, Astellas hopes to further contribute to the health of patients suffering from AML and to support healthcare professionals involved in the treatment of AML by providing new treatment options.

Astellas reflected the impact from this approval in its financial forecasts of the current fiscal year ending March 31, 2019.

"We continue to be encouraged by clinical data on zanubrutinib, including these results, which we believe support its broad global clinical development. Our recent new drug application filing for zanubrutinib in China for patients with relapsed/refractory mantle cell lymphoma (MCL), a type of B-cell lymphoma, is currently under review by the National Medical Products Administration of China, and we are hopeful that it will give patients in China, and across the world, a new treatment option where it is so greatly needed," said Jane Huang, M.D., Chief Medical Officer, Hematology, at BeiGene.

Summary of Preliminary Results from the Phase 1 Trial of Zanubrutinib in Chinese Patients with B-Cell Lymphoma

An ongoing Phase 1 trial of zanubrutinib as a monotherapy in patients with different subtypes of B-cell malignancies, including Waldenström macroglobulinemia (WM), chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) and other non-Hodgkin’s lymphomas (NHL), is being conducted in China. The trial is fully enrolled and comprised of two parts – a dose escalation phase involving 21 patients and a dose-expansion phase of 23 patients treated with zanubrutinib at the recommended Phase 2 dose of 160 mg taken orally twice daily.

Preliminary findings suggested that there was no significant difference in the pharmacokinetic profile of zanubrutinib between Chinese and non-Chinese patients. Preliminary findings also showed complete or greater than 80 percent sustained BTK occupancy was achieved among these patients with both single- and multiple-dose administrations.

As of June 15, 2018, after a median follow-up of 9.5 months (2.3 months–23.4 months), 21 patients (47%) remained on treatment. With 44 patients enrolled in the trial, 34 were evaluable for response. Of the nine patients with CLL/SLL, the overall response rate (ORR) was 100 percent, with two complete responses (CRs), six partial responses (PRs), and a PR with lymphocytosis (PR-L). Of the two patients with mantle cell lymphoma (MCL), there was one CR and one stable disease (SD). Of the two patients with WM, there was one PR and one SD. Of the 26 patients with follicular lymphoma (FL), the ORR was 42 percent with two CRs and nine PRs. There were three patients with FL who were not evaluable at the time of the data cutoff. Of the five patients with marginal zone lymphoma (MZL), there were three SDs and two patients who were not evaluable.

At the time of data cutoff, no dose-limiting toxicities occurred during dose escalation portion of the trial and there were no unexpected safety signals identified in the trial. No deaths related to adverse events were observed in the trial. The most common adverse events (occurring in ≥ 20% of patients) of any attribution among all 44 patients were neutrophil count decreased (50%), anemia (32%), upper respiratory tract infection (25%), white blood cell count decreased (25%), platelet count decreased (23%), rash (23%), hematuria (20%), and hyperuricemia (20%).

"These preliminary safety, tolerability and pharmacokinetics data of zanubrutinib support its ongoing clinical study. In this study, the preliminary results suggest zanubrutinib has a high rate of activity and is generally well-tolerated, which we believe is based on its potency and high-degree of selectivity," said Jun Zhu, M.D., Medical Department Chief at the Beijing Cancer Hospital and study presenter.
