CHMP recommends EU approval of Roche’s Gazyvaro for people with previously untreated advanced follicular lymphoma

On July 21, 2017 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the EU Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Gazyvaro (obinutuzumab) in combination with chemotherapy, followed by Gazyvaro maintenance in people achieving a response, as a new treatment option for previously untreated advanced follicular lymphoma (Press release, Hoffmann-La Roche, JUL 21, 2017, View Source [SID1234519844]). The CHMP’s recommendation is based on results from the phase III GALLIUM study. Follicular lymphoma, the most common type of indolent (slow-growing) non-Hodgkin lymphoma, is considered incurable, and most people relapse repeatedly.1,2 Based on this positive CHMP recommendation, a final decision regarding the approval of Gazyvaro is expected from the European Commission in the near future.

"As follicular lymphoma is considered incurable, better initial treatment options are needed to prevent the disease from returning for as long as possible," said Sandra Horning, MD, Chief Medical Officer and Head of Global Product Development. "MabThera has been the standard of care for the past 20 years. Based on the GALLIUM study, Gazyvaro-based therapy provides superior progression-free survival compared to MabThera-based therapy, setting a new benchmark for what can be achieved with initial therapy for follicular lymphoma."

The GALLIUM study is the first phase III study in previously untreated follicular lymphoma to show superior PFS over MabThera(rituximab)-based treatment, the current standard of care. Results showed that Gazyvaro-based treatment reduced the risk of disease progression or death (progression-free survival; PFS), as evaluated by investigator assessment, by 34 percent (HR=0.66; 95% CI 0.51-0.85, p=0.001) compared to MabThera-based treatment. As supported by an independent review committee (IRC), the risk of disease progression or death was reduced by 29 percent (HR=0.71; 95% CI 0.54-0.93, p=0.014) compared to MabThera/Rituxan-based treatment. Median PFS has not yet been reached in either treatment arm. Investigator assessment showed that at three years, 80.0 percent of patients who received Gazyvaro-based treatment were progression-free compared to 73.3 percent of patients who received MabThera-based treatment. Adverse events with either Gazyvaro or MabThera were consistent with those seen in previous studies.

About the GALLIUM study
GALLIUM (NCT01332968) is a global Phase III open-label, multi-centre, randomised two-arm study examining the efficacy and safety of Gazyvaro plus chemotherapy followed by Gazyvaro alone for up to two years, as compared head-to-head against MabThera plus chemotherapy followed by MabThera alone for up to two years or until disease progression (whichever occurs first). Chemotherapies (CHOP, CVP or bendamustine) were selected by each participating study site prior to beginning enrolment. GALLIUM included 1401 patients with previously untreated indolent non-Hodgkin lymphoma (iNHL), of which 1202 patients had follicular lymphoma. The primary endpoint of the study was investigator-assessed PFS in patients with follicular lymphoma, with secondary endpoints including PFS assessed by IRC, PFS in the overall study population (iNHL), response rate (overall response, ORR; and complete response, CR), overall survival (OS), and safety. The GALLIUM study is being conducted in cooperation with the NCRI (United Kingdom), GLSG (Germany), the East German Study Group Hematology and Oncology (OSHO; Germany).

About Gazyvaro (obinutuzumab)
Gazyvaro is an engineered monoclonal antibody designed to attach to CD20, a protein expressed on certain B cells, but not on stem cells or plasma cells. Gazyvaro is designed to attack and destroy targeted B-cells both directly and together with the body’s immune system.

Gazyvaro is marketed as Gazyva outside the EU and Switzerland. Gazyva/Gazyvaro is currently approved in more than 80 countries in combination with chlorambucil, for people with previously untreated chronic lymphocytic leukaemia (CLL), and in combination with bendamustine for people with certain types of previously treated follicular lymphoma. The approvals in CLL were based on the CLL11 study, showing significant improvements with Gazyvaro plus chlorambucil across multiple clinical endpoints, including PFS, overall response rate (ORR), complete response rate (CR), and minimal residual disease (MRD) when compared head-to-head with MabThera plus chlorambucil.

The approvals in certain types of previously treated follicular lymphoma were based on the phase III GADOLIN study, in people with follicular lymphoma who did not respond to or who progressed during or within six months of prior MabThera -based therapy, showing a significant improvement in PFS and overall survival (OS) with Gazyvaro-based therapy compared to bendamustine alone.

Additional combination studies investigating Gazyvaro with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are underway across a range of blood cancers.

About Follicular Lymphoma
Follicular lymphoma is the most common indolent (slow-growing) form of non-Hodgkin lymphoma (NHL), accounting for about one in five cases of NHL.1 It is considered incurable and relapse is common. Every day, more than 50 people in Europe are diagnosed with this type of NHL2. It is estimated that more than 75,000 people are diagnosed with follicular lymphoma each year worldwide2.

CHMP recommends EU approval for Roche’s TECENTRIQ (atezolizumab) in a specific type of metastatic lung and two types of metastatic bladder cancer

On July 21, 2017 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the EU Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for TECENTRIQ (atezolizumab) as a monotherapy for the treatment of adults with locally advanced or metastatic non-small cell lung cancer (NSCLC) after they have been previously treated with chemotherapy (Press release, Hoffmann-La Roche, JUL 21, 2017, View Source [SID1234519843]). People with EGFR activating mutations or ALK positive tumour mutations should also have received targeted therapy before receiving TECENTRIQ. This positive recommendation is based on results from the large randomised Phase III OAK study and the randomised Phase II POPLAR study. The CHMP has also adopted a positive opinion for the use of TECENTRIQ as a monotherapy for the treatment of adults with locally advanced or metastatic urothelial carcinoma (mUC) who have been previously treated with a platinum based chemotherapy or who are considered ineligible for cisplatin chemotherapy. This positive opinion is based on results from the randomised Phase III IMvigor211 study and cohorts 1 and 2 from the single-arm Phase II IMvigor210 study.

"This positive CHMP opinion represents great news for people living with either advanced lung or bladder cancer because, despite recent developments, long-term survival rates for people with these cancers are inferior to those with other common cancers," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We are encouraged that the CHMP considered the totality of the data for TECENTRIQ including the importance of key clinical endpoints, such as long-term responses."
Based on this positive CHMP opinion, a final decision from the European Commisssion is expected in the near future. TECENTRIQ is already approved in the US and in a number of other countries for people with metastatic NSCLC; and for people with locally advanced or mUC and who are not eligible for cisplatin chemotherapy, or who have disease progression during or following platinum-containing therapy.
About the OAK study
OAK is a global, multicentre, open-label, randomised, controlled Phase III study that evaluated the efficacy and safety of TECENTRIQ compared with docetaxel. It enrolled 1225 patients with both squamous and non-squamous disease, regardless of the programmed death-ligand 1 (PD-L1) status of their tumours, and randomised them (1:1) to receive either TECENTRIQ administered intravenously at 1,200 mg every 3 weeks or docetaxel administered intravenously at 75 mg/m2 every 3 weeks. The co-primary endpoints were overall survival (OS) in the first 850 randomised patients (intention-to-treat population) and in a PD-L1-selected subgroup of this primary analysis population.
The OAK study showed that TECENTRIQ helped people in the overall study population live a median of 13.8 months – 4.2 months longer than those treated with docetaxel chemotherapy (median overall survival [OS]: 13.8 vs. 9.6 months; HR = 0.73, 95% CI: 0.62, 0.87).

CI=confidence interval; DOR=duration of response; IC=tumour-infiltrating immune cells; NE=not estimable; ORR=objective response rate; OS=overall survival; PFS=progression-free survival; RECIST=Response Evaluation Criteria in Solid Tumours v1.1; *All comers refers to the primary analysis population consisting of the first 850 randomised patients ǂStratified by PD-L1 expression in tumour infiltrating immune cells, the number of prior chemotherapy regimens, and histology ** Based on the stratified log-rank test
About the POPLAR study
A phase II, multi-centre, international, randomised, open-label, controlled study, POPLAR, was conducted in patients with locally advanced or metastatic NSCLC who progressed during or following a platinum-containing regimen, regardless of PD-L1 expression. The primary efficacy outcome was overall survival. A total of 287 patients were randomised 1:1 to receive either TECENTRIQ (1,200 mg by intravenous infusion every 3 weeks until loss of clinical benefit) or docetaxel (75 mg/m2 by intravenous infusion on day 1 of each 3-week cycle until disease progression). Randomisation was stratified by PD-L1 expression status on IC, by the number of prior chemotherapy regimens and by histology.
An updated analysis with a total of 200 deaths observed and a median survival follow-up of 22 months showed a median OS of 12.6 months in patients treated with TECENTRIQ, vs. 9.7 months in patients treated with docetaxel (HR of 0.69, 95% CI: 0.52, 0.92). ORR was 15.3% vs. 14.7% and median DOR was 18.6 months vs. 7.2 months for TECENTRIQ vs. docetaxel, respectively.
About non-small cell lung cancer
Lung cancer is the leading cause of cancer death globally. Each year 1.59 million people die as a result of the disease; this translates into more than 4,350 deaths worldwide every day. Lung cancer can be broadly divided into two major types: NSCLC and small cell lung cancer. NSCLC is the most prevalent type, accounting for around 85% of all cases.
About the IMvigor211 study
IMvigor211 is a Phase III study of TECENTRIQ compared to chemotherapy in people with advanced bladder cancer who were previously treated with a platinum-based chemotherapy. The study evaluated the efficacy and safety of TECENTRIQ compared to chemotherapy of physician choice (vinflunine, paclitaxel or docetaxel) administered every three weeks in 931 people with previously-treated mUC who progressed during or following a platinum-based regimen. The primary efficacy endpoint was OS and key secondary endpoints include objective response rate, progression-free survival, duration of response and safety. IMvigor211 study did not meet its primary endpoint of overall survival (OS) compared to chemotherapy. These data were presented in full at the EACR-AACR-SIC Special Conference 2017.
The primary efficacy endpoint, overall survival, was to be tested in a successive fashion (hierarchical testing) in study populations defined by PD-L1 expression. The first population tested was people with the highest levels of PD-L1 expression (IC2/3), followed by those with any observable level of PD-L1 expression (IC1/2/3), and followed by the overall study population (Intention-To-Treat; ITT). Per the pre-specified hierarchical testing order, the IC2/3 (≥5%) population was tested first, with an OS HR of 0.87 (95% CI: 0.63, 1.21; median OS of 11.1 vs. 10.6 months for TECENTRIQ and chemotherapy respectively). In the overall study population (intention-to-treat or ITT) people treated with TECENTRIQ achieved a mOS of 8.6 months (CI: 95%; 7.8, 9.6) compared to 8.0 months (CI: 95%; 7.2, 8.6) with chemotherapy (HR 0.85, 95% CI 0.73-0.99).
Statistical significance needed to be achieved for the study populations in the following order: IC2/3 (≥5%), IC1/2/3 (≥1%), and ITT group. However, because statistical significance was not achieved for OS in the IC2/3 population, results could not be evaluated for statistical significance in the IC1/2/3 and ITT populations and those analyses are considered descriptive in nature.
Overall Response Rates (ORR) were similar to those previously reported in the phase II IMvigor210 study and similar between the two study arms. The median duration of response (mDOR), a secondary endpoint, for those receiving TECENTRIQ was 21.7 months (95% CI: 13.0, 21.7) in the overall study population, compared to 7.4 months (95% CI: 6.1, 10.3) for those receiving chemotherapy. At the time of data cutoff, the majority (63%) of people who responded to treatment with TECENTRIQ continued to respond, compared to 21% of people treated with chemotherapy.
About the IMvigor210 study (Cohort 2)
In Cohort 2, the co-primary efficacy endpoints were confirmed ORR as assessed by an IRF using RECIST v1.1 and investigator-assessed ORR according to Modified RECIST (mRECIST) criteria. There were 310 patients treated with TECENTRIQ 1,200 mg by intravenous infusion every 3 weeks until loss of clinical benefit. The study met its co-primary endpoints in Cohort 2, demonstrating statistically significant ORRs per IRF-assessed RECIST v1.1 and investigator-assessed mRECIST compared to a pre-specified historical control response rate of 10%.
An analysis was also performed with a median duration of survival follow-up of 21.1 months for Cohort 2. The confirmed ORRs per IRF-RECIST v1.1 were 28.0% (95% CI: 19.5, 37.9) in patients with PD-L1 expression IC2/3 (≥ 5%), 19.3% (95% CI: 14.2, 25.4) in patients with PD-L1 expression IC1/2/3 (≥ 1%), and 15.8% (95% CI: 11.9, 20.4) in all comers. The confirmed ORR per investigator-assessed mRECIST was 29.0% (95% CI: 20.4, 38.9) in patients with PD-L1 expression ≥ 5%, 23.7% (95% CI: 18.1, 30.1) in patients with PD-L1 expression ≥ 1%, and 19.7% (95% CI: 15.4, 24.6) in all comers. The rate of complete response per IRF-RECIST v1.1 in the all comer population was 6.1% (95% CI: 3.7, 9.4). For Cohort 2, median DOR per IRF-RECIST v1.1 was not reached in any PD-L1 expression subgroup or in all comers, however was reached in patients with PD-L1 expression < 1% (13.3 months; 95% CI 4.2, NE). The OS rate at 12 month was 37% in all comers.
About the IMvigor210 study (Cohort 1)
The positive CHMP opinion for patients who are ineligible for cisplatin-based chemotherapy is based on results from Cohort 1, which consisted of 119 people with locally advanced or mUC who were ineligible for cisplatin-containing chemotherapy and were either previously untreated or had disease progression at least 12 months after neoadjuvant (before surgery) or adjuvant (after surgery) chemotherapy. The primary endpoint of the study was objective response rate (ORR).

CI=confidence interval; DOR=duration of response; IC= tumour-infiltrating immune cells; IRF= independent review facility; NE=not estimable; ORR=objective response rate; OS=overall survival; PFS=progression-free survival; RECIST=Response Evaluation Criteria in Solid Tumours v1.1.
Pooled Safety Profile
The safety of TECENTRIQ is based on pooled data in 2,160 patients with mUC and NSCLC. The most common adverse all grade reactions were fatigue (35.4%), decreased appetite (25.5%), nausea (22.9%), dyspnoea (21.8%), diarrhoea (18.6%), pyrexia (18.3%), rash (18.6%), vomiting (15.0%), arthralgia (14.2%), asthenia (13.8%) and pruritus (11.3%).
About metastatic urothelial carcinoma
Metastatic urothelial carcinoma (mUC) is associated with a poor prognosis and limited treatment options. It is a disease that has seen no major advances for more than 30 years outside of the US. UC is the ninth most common cancer worldwide, with 430,000 new cases diagnosed in 2012, and it results in approximately 145,000 deaths globally each year. Men are three times more likely to suffer from UC, compared with women, and the disease is three times more common in developed countries than in less developed countries.
About TECENTRIQ (atezolizumab)
TECENTRIQ is a monoclonal antibody designed to bind with a protein called PD-L1. TECENTRIQ is designed to bind to PD-L1 expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, TECENTRIQ may enable the activation of T cells. TECENTRIQ has the potential to be used as a foundational combination partner with cancer immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers

U.S. FDA Grants Orphan-Drug Designation to Astellas for Development of FLT3 Inhibitor Gilteritinib in Acute Myeloid Leukemia

On July 20, 2017 Astellas Pharma Inc. (TSE: 4503, President and CEO: Yoshihiko Hatanaka, "Astellas") reported that the U.S. Food and Drug Administration (FDA) granted orphan-drug designation to gilteritinib in patients with acute myeloid leukemia (AML) (Press release, Astellas, JUL 20, 2017, View Source [SID1234519842]). The Orphan Drug Designation program assigns status to drugs and biologics intended for the safe and effective treatment, diagnosis or prevention of diseases or disorders that affect fewer than 200,000 people in the United States.

"Fewer than 10,000 Americans will be diagnosed with FLT3 mutation-positive AML this year and while that may be a small percentage of the overall population, it is an important group of patients who are deserving of potential new treatments," said Steven Benner, M.D., senior vice president and global therapeutic area head, oncology development, Astellas. "We are grateful to the FDA for acknowledging the unique needs of rare diseases and for providing a path forward for gilteritinib in supporting these patients."

Gilteritinib is a receptor tyrosine kinase inhibitor of FLT3 and AXL, which are involved in the growth of cancer cells. Gilteritinib has demonstrated inhibitory activity against FLT3 internal tandem duplication (ITD) as well as tyrosine kinase domain (TKD), two common types of FLT3 mutations that are seen in up to one third of patients with AML. AML is a cancer that impacts the blood and bone marrow and most commonly experienced in older adults. According to the American Cancer Society, in 2016 there were an estimated 21,000 new cases of AML diagnosed in the United States and about 10,600 cases resulted in death.

Astellas is currently investigating gilteritinib in various AML patient populations through several planned and already initiated Phase 3 trials, including the registrational ADMIRAL trial in relapsed/refractory FLT3+ AML.

The safety and efficacy of the agent discussed herein are under investigation and have not been established. There is no guarantee that the agent will receive regulatory approval and become commercially available for the uses being investigated.
