About Tucatinib

Tucatinib is an investigational, orally bioavailable, potent tyrosine kinase inhibitor that is highly selective for HER2 without inhibition of the EGFR. Inhibition of EGFR has been associated with clinically relevant toxicities, including skin rash and diarrhea. Tucatinib has shown activity as a single agent and in combination with both chemotherapy and other HER2 directed agents such as trastuzumab and T-DM1.1,2 Studies of tucatinib in these combinations have shown activity both systemically and in brain metastases. HER2 is a growth factor receptor that is overexpressed in multiple cancers, including breast, ovarian and gastric cancers. HER2 mediates cell growth, differentiation and survival. Tumors that overexpress HER2 (HER2-positive) are more aggressive and historically have been associated with poor overall survival, compared with HER2-negative cancers.

On August 28, 2017 AVEO Oncology (NASDAQ: AVEO) reported that the European Commission (EC) has approved FOTIVDA (tivozanib) for the treatment of adult patients with advanced renal cell carcinoma (RCC) in the European Union plus Norway and Iceland (Press release, AVEO, AUG 28, 2017, View Source [SID1234520319]). Tivozanib is indicated for the first line treatment of adult patients with advanced RCC and for adult patients who are vascular endothelial growth factor receptor (VEGFR) and mTOR pathway inhibitor-naïve following disease progression after one prior treatment with cytokine therapy for advanced RCC.i EUSA Pharma, a specialty pharmaceutical company with a focus on oncology and oncology supportive care, is the European licensee for tivozanib. Tivozanib is an oral, once-daily, potent and highly-selective vascular endothelial growth factor receptor tyrosine kinase inhibitor (VEGFR-TKI).

Dr. Bernard Escudier, Medical Oncologist and member of the Genitourinary Tumour Board of Gustave Roussy, France, commented "This is excellent news for patients with metastatic RCC. Outcomes in this disease have greatly improved with the introduction of targeted therapies, meaning that patients are living for longer. However, we are still in need of effective and well tolerated new treatments in metastatic RCC and thus, tivozanib is a welcomed addition."

The approval from the EC follows the recommendation from the Committee for Medical Products for Human Use (CHMP).i1 The decision was primarily based on data from a global, open-label, randomized, multi-center Phase 3 trial (TIVO-1)i,iii which evaluated the efficacy and tolerability of tivozanib compared to a currently available comparator VEGFR-TKI treatment (sorafenib) in 517 patients with advanced RCC. Patients treated with tivozanib experienced superior PFS (11.9 vs. 9.1 months in the overall population [HR, 0.797; 95% CI, 0.639 to 0.993; P =.042] and 12.7 vs. 9.1 months in treatment naïve patients [HR, 0.756; 95% CI, 0.580 to 0.985; P =.037]) versus sorafenib.iii There was also an improved side effect profile with tivozanib, with only 14% (versus 43% with sorafenib) requiring a dose reduction due to adverse events (AEs). In addition, fewer people on tivozanib experienced burdensome side effects, such as diarrhea (23% vs 33%) and hand-foot syndrome (14% vs 54%).iii

EUSA Pharma has indicated that it intends to now work with the necessary health authorities to make tivozanib available to advanced RCC patients across Europe as quickly as possible.

"The European Commission’s decision is the first regulatory approval of tivozanib globally, and a tremendous accomplishment for AVEO and its partner, EUSA Pharma. We are very pleased that tivozanib is now available to patients in Europe," said Michael Bailey, president and chief executive officer of AVEO. "We also continue to make progress on the next two pillars in our tivozanib strategy: U.S. registration, driven by the pivotal Phase 3 TIVO-3 trial, which is expected to read out in the first quarter of 2018; and immunotherapy combination trials, starting with the TiNivo trial, our Opdivo combination trial. European approval further strengthens our balance sheet by triggering an R&D payment to AVEO and provides AVEO the opportunity to achieve multiple potential commercial milestone payments, as well as royalty payments on sales, that would support our execution of the tivozanib strategy."

Under the terms of their December 2015 agreement, EUSA Pharma has agreed to pay AVEO up to $394 million in future milestone payments and research and development funding, assuming successful achievement of specified development, regulatory and commercialization objectives. In addition, a tiered royalty will be due to AVEO ranging from a low double-digit up to mid-twenty percent on net sales of tivozanib in the agreement’s territories. European marketing approval for tivozanib triggers a $4 million research and development payment from EUSA, and AVEO will also be eligible for up to $12 million in additional milestones from EUSA based on reimbursement and regulatory approvals. In the territories licensed to EUSA, thirty percent of milestone and royalty payments received by AVEO, excluding research and development funding, are due to Kyowa Hakko Kirin (KHK) as a sublicensing fee. In the territories retained by AVEO, the royalty obligation to KHK ranges from the low- to mid-teens on net sales.

About RCC in Europe

RCC is the most common form of kidney cancer,iv which accounts for an estimated 49,000 deaths in Europe each year.v It is expected to be one of the fastest increasing cancers over the next ten years.vi Tyrosine Kinase Inhibitor (TKI) vascular endothelial growth factor (VEGF) inhibitors are the standard of care treatment for advanced RCC in Europe, however, patients on current treatments can often experience significant side effects.iii,vii

About Tivozanib (FOTIVDA)

Tivozanib (FOTIVDA) is an oral, once-daily, vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI) discovered by Kyowa Hakko Kirin and approved for the treatment of adult patients with advanced renal cell carcinoma in the European Union plus Norway and Iceland. It is a potent, selective and long half-life inhibitor of all three VEGF receptors and is designed to optimize VEGF blockade while minimizing off-target toxicities, potentially resulting in improved efficacy and minimal dose modifications. Tivozanib has been investigated in several tumors types, including renal cell, colorectal and breast cancers.

On August 28, 2017 Gilead Sciences, Inc. (Nasdaq: GILD) and Kite Pharma, Inc.

Kite is an industry leader in the emerging field of cell therapy, which uses a patient’s own immune cells to fight cancer. The company has developed engineered cell therapies that express either a chimeric antigen receptor (CAR) or an engineered T cell receptor (TCR), depending on the type of cancer. Kite’s most advanced therapy candidate, axicabtagene ciloleucel (axi-cel), is a CAR T therapy currently under priority review by the U.S. Food and Drug Administration (FDA). It is expected to be the first to market as a treatment for refractory aggressive non-Hodgkin lymphoma, which includes diffuse large B-cell lymphoma (DLBCL), transformed follicular lymphoma (TFL) and primary mediastinal B-cell lymphoma (PMBCL). The FDA has set a target action date of November 29, 2017 under the Prescription Drug User Fee Act (PDUFA). A marketing authorization application (MAA) has also been filed for axi-cel for the treatment of relapsed/refractory DLBCL, TFL and PMBCL with the European Medicines Agency (EMA), representing the first submission in Europe for a CAR T therapy. Approval in Europe is expected in 2018. Kite has additional candidates in clinical trials in both hematologic cancers and solid tumors, including KITE-585, a CAR T therapy candidate that targets BCMA expressed in multiple myeloma.

"The acquisition of Kite establishes Gilead as a leader in cellular therapy and provides a foundation from which to drive continued innovation for people with advanced cancers," said John F. Milligan, PhD, Gilead’s President and Chief Executive Officer. "The field of cell therapy has advanced very quickly, to the point where the science and technology have opened a clear path toward a potential cure for patients. We are greatly impressed with the Kite team and what they have accomplished, and share their belief that cell therapy will be the cornerstone of treating cancer. Our similar cultures and histories of driving rapid innovation in order to bring more effective and safer products to as many patients as possible make this an excellent strategic fit."

Research and development as well as the commercialization operations for Kite will remain based in Santa Monica, California, with product manufacturing remaining in El Segundo, California.

"From the release of our pivotal data for axi-cel, to our potential approval by the FDA, this is a year of milestones. Each and every accomplishment is a reflection of the talent that is unique to Kite. We are excited that Gilead, one of the most innovative companies in the industry, recognized this value and shares our passion for developing cutting-edge and potentially curative therapies for patients," said Arie Belldegrun, MD, FACS, Chairman, President and Chief Executive Officer of Kite. "CAR T has the potential to become one of the most powerful anti-cancer agents for hematologic cancers. With Gilead’s expertise and support, we hope to fulfill that potential by rapidly accelerating our robust pipeline and next-generation research and manufacturing technologies for the benefit of patients around the world."

On august 28, 2017 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) and granted Priority Review for Gazyva (obinutuzumab) in combination with chemotherapy followed by Gazyva alone for people with previously untreated follicular lymphoma, one of the most common blood cancers among adults (Press release, Hoffmann-La Roche, AUG 28, 2017, View Source [SID1234520315]). Follicular lymphoma, a slow-growing (indolent) form of non-Hodgkin lymphoma, is incurable and characterized by cycles of remission and relapse.
"Follicular lymphoma becomes harder to treat each time it returns, and the goal of initial treatment is to prevent the cancer from progressing for as long as possible," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. "Based on the GALLIUM study, Gazyva-based treatment significantly improved progression-free survival over the current standard of care, and we are committed to bringing this potential new option to patients as soon as possible."

The sBLA is based on results of the GALLIUM study, which is the first Phase III study in previously untreated follicular lymphoma to show superior progression-free survival (PFS) over Rituxan (rituximab)-based treatment, the current standard of care. Adverse events (AEs) with either Gazyva or Rituxan were consistent with those seen in previous studies.

The FDA is expected to make a decision on approval under Priority Review by 23 December, 2017. Priority Review designation is granted to medicines that the FDA has determined to have the potential to provide significant improvements in the safety and effectiveness of the treatment, prevention or diagnosis of a serious disease. Additional submissions of the GALLIUM data to health authorities around the world are ongoing.

About the GALLIUM study
GALLIUM (NCT01332968) is a global Phase III open-label, multicenter, randomized two-arm study examining the efficacy and safety of Gazyva plus chemotherapy followed by Gazyva alone for up to two years, as compared head-to-head against Rituxan plus chemotherapy followed by Rituxan alone for up to two years. Chemotherapies used were CHOP, CVP or bendamustine and were selected by each participating study site prior to beginning enrollment.

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 progression-free survival (PFS) in patients with follicular lymphoma, with secondary endpoints including PFS assessed by independent review committee (IRC) in patients with follicular lymphoma, PFS in the overall study population (iNHL), response rate (overall response, ORR; and complete response, CR), overall survival (OS) and safety. The study is being conducted in cooperation with the GLSG (Germany), the East German Study Group Hematology and Oncology (OSHO; Germany) and the NCRI (United Kingdom). Results after a follow-up period of 41.1 months showed:
Gazyva-based treatment reduced the risk of disease worsening or death (PFS, as assessed by investigator) by 32 percent compared to Rituxan-based treatment (HR=0.68; 95 percent CI 0.54-0.87; p=0.0016).

IRC-assessed PFS was consistent with investigator-assessed PFS. As assessed by IRC, Gazyva-based treatment reduced the risk of disease worsening or death by 28 percent compared to Rituxan-based treatment (HR=0.72; 95 percent CI 0.56-0.93; p=0.0018). Median PFS has not yet been reached in either treatment arm.

The most common Grade 3-5 AEs that occurred more often in the Gazyva arm compared to the Rituxan arm were low white blood cell count (neutropenia, 46.7 percent vs. 39.5 percent), infections (20.3 percent vs. 16.4 percent), infusion-related reactions (IRRs, 12.4 percent vs. 6.7 percent), low platelet count (thrombocytopenia, 6.1 percent vs. 2.7 percent), new tumors (second malignancies, 4.7 percent vs. 2.7 percent) and cardiac events (3.9 percent vs. 2.8 percent).

GALLIUM is the third positive Phase III study for Gazyva, following the CLL11 study in patients with previously untreated chronic lymphocytic leukaemia (CLL) and the GADOLIN study in patients with indolent (slow-growing) non-Hodgkin lymphoma whose disease progressed during or within six months of prior Rituxan-based therapy.

About Gazyva (obinutuzumab)
Gazyva 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. Gazyva is designed to attack and destroy targeted B-cells both directly and together with the body’s immune system.

Gazyva is marketed as Gazyvaro in 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 Gazyva/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/Rituxan 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/Rituxan-based therapy, showing a significant improvement in PFS and overall survival (OS) with Gazyva/Gazyvaro-based therapy compared to bendamustine alone.

Additional combination studies investigating Gazyva/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 NHL1. 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.
About Roche in haematology

On August 28, 2017 AstraZeneca reported that the US Food and Drug Administration (FDA) has approved Faslodex (fulvestrant) 500mg as monotherapy for expanded use in women with hormone-receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer, who have gone through menopause and have not received previous endocrine therapy (Press release, AstraZeneca, AUG 28, 2017, View Source [SID1234520314]).

The FDA approval is based on data from the Phase III FALCON trial, which were published in the November 2016 issue of The Lancet.

Jamie Freedman, Executive Vice President, Head of the Oncology Business Unit, AstraZeneca said: "We’re pleased that the landmark FALCON trial results demonstrated the efficacy of Faslodex as initial monotherapy treatment for women who are living with HR+ HER2- advanced breast cancer. This approval, building on more than 15 years of clinical experience, means more patients can have the opportunity to receive Faslodex earlier in the treatment journey."

Matthew Ellis, MD, PhD, Director of the Lester and Sue Smith Breast Center, part of the NCI-designated Dan L Duncan Comprehensive Cancer Center at Baylor College of Medicine, said: "This study provides evidence that using fulvestrant as the first option for previously untreated hormone receptor-positive advanced breast cancer will prolong the time before the disease advances and alternative therapies are required."

The FALCON trial was designed to demonstrate superiority and included 462 postmenopausal women with HR+ metastatic or locally-advanced breast cancer. The results showed a statistically-significant increase in investigator-assessed median progression-free survival (PFS), representing a 20% reduction in the risk of disease progression or death – median PFS of 16.6 months in patients who received Faslodex, compared to 13.8 months in patients receiving the aromatase inhibitor anastrozole 1mg (HR: 0.797; 95% CI: 0.637-0.999; p=0.049).

Faslodex is a hormonal therapy that targets the oestrogen receptor (ER), which can influence the growth of HR+ metastatic breast cancer (MBC), and helps to slow cancer growth by blocking the ER and targeting it for degradation. The most common adverse reactions (≥10%) of any grade reported in patients in the Faslodex arm were arthralgia, hot flash, fatigue, and nausea.

About FALCON

The FALCON (Fulvestrant and AnastrozoLe COmpared in hormonal therapy-Naïve advanced breast cancer) trial is a Phase III, randomised, double-blind, multicentre trial comparing the antitumour effects and tolerability profile of a 500mg dose of Faslodexplus placebo with a 1mg dose of anastrozole plus placebo, in postmenopausal women with HR+, locally-advanced or metastatic breast cancer who have not been treated previously with any hormonal medicine.

The FALCON trial was designed on the basis of positive results from the Phase II FIRST trial, which demonstrated a median overall survival nearly six months longer with Faslodex compared to anastrozole.

About Advanced Breast Cancer

Advanced/metastatic breast cancer refers to Stage III and IV breast cancer. Stage III disease may also be referred to as locally-advanced breast cancer, while metastatic disease is the most-advanced stage of breast cancer (Stage IV), and occurs when cancer cells have spread beyond the initial tumour site to other organs of the body outside the breast. Since there is no cure for the disease, the goal of current treatment is to delay disease worsening or death.

About Faslodex

First approved in 2002, Faslodex was used as a monotherapy for the treatment of postmenopausal women with HR+ MBC whose cancer had progressed following prior anti-oestrogen therapy. In 2016, FDA approved Faslodex in combination with palbociclib for the treatment of women with HR+, HER2- advanced or MBC, whose cancer has progressed after endocrine therapy.

On 26 July 2017, the European Commission (EC) approved Faslodex for the treatment of oestrogen-receptor positive, locally-advanced breast cancer in postmenopausal women not previously treated with endocrine therapy.
