Immunocore’s IMCgp100 Receives Promising Innovative Medicine (PIM) Designation Under UK Early Access to Medicines Scheme (EAMS) for the Treatment of Patients with Uveal Melanoma

On December 11,2017 Immunocore Limited, the world’s leading TCR company focused on delivering first-in-class biological therapies that transform lives, reported that it has been informed by the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) that IMCgp100 has been granted Promising Innovative Medicines (PIM) designation for the treatment of patients with metastatic uveal melanoma(Press release, Immunocore, DEC 11, 2017, View Source [SID1234522505]).

PIM designation is an early indication that IMCgp100 is a promising candidate for the UK’s Early Access to Medicines Scheme (EAMS), intended for the treatment, diagnosis or prevention of metastatic uveal melanoma. This is based on early Phase I clinical trial data published at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) annual meeting in November. IMCgp100 will be a suitable candidate for entry into Step II of the EAMS process, for which Immunocore is in a pivotal registrational clinical trial in patients with metastatic uveal melanoma. Following this, IMCgp100 will enter the EAMS scientific opinion assessment step.

For more information on clinical trials involving IMCgp100, please visit clintrials.gov.

James Sandy, Chief Development Officer at Immunocore, commented: "We are delighted by the MHRA’s decision to award PIM designation to IMCgp100, which gives us scope to accelerate the approval process for IMCgp100, and bringing us a step closer toward making IMCgp100 available for patients with uveal melanoma, for which there are currently no effective treatment options available."

IMCgp100 was granted Orphan Drug Designation by the US Food and Drug Administration (FDA) in January 2016 and participated in the EMA’s Adaptive Pathways Pilot Programme.

Phase III IMmotion151 study showed Roche’s Tecentriq (atezolizumab) and Avastin (bevacizumab) reduced the risk of disease worsening or death for the initial treatment of certain people with advanced kidney cancer

On December 11, 2017 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the Phase III IMmotion151 study met its co-primary endpoint of investigator-assessed progression-free survival (PFS) and demonstrated that the combination of Tecentriq (atezolizumab) and Avastin (bevacizumab) provided a statistically significant and clinically meaningful reduction in the risk of disease worsening or death (PFS) in people whose disease expressed the PD-L1 (programmed death-ligand 1: Expression ≥1%) protein compared with sunitinib for the first-line treatment of people who have advanced or metastatic renal cell carcinoma (mRCC) (Press release, Hoffmann-La Roche, DEC 11, 2017, View Source [SID1234522504]).

Observations of a pre-specified subgroup analysis of the Tecentriq and Avastin combination indicated that, in people whose disease expressed PD-L1, a numerical difference favouring Tecentriq was seen across all patient risk factor groups (favourable, intermed­iate and poor) compared to sunitinib; however, due to the study design these data could not be assessed for statistical significance and are descriptive only. Assessment of secondary endpoints is ongoing. Safety for the Tecentriq and Avastin combination appeared consistent with the known safety profile of the individual medicines and what was previously reported in the Phase II IMmotion150 study. No new safety signals were identified with the combination.

Results will be presented at an upcoming oncology conference in 2018. Top-line results from the co-primary endpoint of overall survival (OS) are not mature.

"We are encouraged by these results as they add to the emerging body of evidence that supports our rationale for this combination. We believe that the regimen of Tecentriq and Avastin may enhance the potential of the immune system in the initial treatment of advanced kidney cancer," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We will discuss these data with health authorities globally and hope to bring this combination forward as a potential new treatment option to patients as soon as possible.’’
IMmotion151 is the second successive positive Phase III study of Tecentriq that includes an Avastin combination component as an initial treatment. This follows the positive Phase III non-squamous non-small cell lung cancer (NSCLC) IMpower150 study that showed Tecentriq and Avastin plus chemotherapy demonstrated a PFS advantage over Avastin plus chemotherapy.

About the IMmotion151 study
IMmotion151 is a Phase III multicentre, randomised, open-label study to evaluate the efficacy and safety of Tecentriq and Avastin versus sunitinib in people with inoperable, locally advanced or metastatic renal cell carcinoma (RCC) who have not received prior systemic active or experimental therapy. It enrolled 915 people globally who were randomised 1:1 to receive Tecentriq and Avastin, or sunitinib alone.

People in the Tecentriq and Avastin arm received Tecentriq at a fixed dose of 1200 milligrams (mg) and Avastin at a dose of 15 milligrams per kilogram (mg/kg) via intravenous (IV) infusion every 3 weeks until loss of clinical benefit or unacceptable toxicity. People in the sunitinib arm received sunitinib 50 mg orally, once daily for 4 weeks followed by 2 weeks rest until loss of clinical benefit or unacceptable toxicity.

The co-primary endpoints were PFS, as determined by the investigator using Response Evaluation Criteria in Solid Tumours Version 1.1 (RECIST v1.1) in people whose tumours expressed PD-L1 [PD-L1 expression ≥1 percent on immune cells (IC)], and OS in the overall study population (intention-to-treat, ITT). PD-L1 expression was prospectively assessed using an immunohistochemistry (IHC) test (SP142) developed by Roche Tissue Diagnostics.
Stratification factors included the presence or absence of liver metastases; level of IC staining for PD-L1 (≥1 percent vs. <1 percent) and Memorial Sloan-Kettering Cancer Center (Motzer) risk score. The Motzer prognostic scoring system predicts for OS based upon an individual’s baseline clinical and laboratory characteristics.
Depending on the presence of one or several of five variables (risk factors), patients are classified in one of the three risk groups: ‘Favourable’ with 0 risk factors, ‘Intermediate’ with 1–2 risk factors and ‘Poor’ with ≥ 3 risk factors.

About RCC
Kidney cancer remains one of the most common cancers in the world, accounting for over 140,000 deaths worldwide each year,1 with renal cell carcinoma (RCC) accounting for approximately 90% of all cases.2 Over 300,000 people are diagnosed with RCC every year and currently only about 1 in 10 people are alive beyond 5 years following diagnosis of metastatic disease.

RCC occurs when abnormal cells develop in the tissue of the kidneys, specifically in the small tubes (also known as tubules) where our blood is filtered.4 Typically, RCC is a single tumour in one kidney but, in rare cases, there can be multiple tumours, which can occur in one or both kidneys.

Despite recent progress in the field of kidney cancer, treatment options for people with the disease remains limited.

About Tecentriq (atezolizumab)
Tecentriq is a monoclonal antibody designed to bind with a protein called 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.

Tecentriq is already approved in the European Union, United States and more than 50 countries for people with previously treated metastatic NSCLC and for people with locally advanced or metastatic urothelial cancer (mUC) who are not eligible for cisplatin chemotherapy, or who have had disease progression during or following platinum-containing therapy.

About Avastin (bevacizumab) in RCC
Avastin (bevacizumab) is an anti-VEGF inhibitor. VEGF (vascular endothelial growth factor) is a protein that stimulates the formation and maintenance of blood vessels and has been shown to play a key role in the development of RCC.
RCC tumours are highly vascularised, meaning they have many blood vessels and also exhibit a high concentration of VEGF5. There is, therefore a strong rationale for medicines such as Avastin that block the VEGF pathway. Avastin is the only currently available treatment for patients with mRCC that directly inhibits VEGF.

There is a strong scientific rationale to support further investigation of Tecentriq and Avastin in combination. The Tecentriq and Avastin regimen may enhance the potential of the immune system to combat first-line advanced NSCLC and mRCC. Avastin, in addition to its established anti-angiogenic effects, may further enhance Tecentriq’s ability to restore anti-cancer immunity, by inhibiting VEGF-related immunosuppression, promoting T-cell tumour infiltration and enabling priming and activation of T-cell responses against tumour antigens.

About Roche in cancer immunotherapy
For more than 50 years, Roche has been developing medicines with the goal to redefine treatment in oncology. Today, we’re investing more than ever in our effort to bring innovative treatment options that help a person’s own immune system fight cancer.

Results of Phase 1b/2 Dose Regimen Optimization Studies for ALXN1210 in Patients with Paroxysmal Nocturnal Hemoglobinuria (PNH) Presented at American Society of Hematology (ASH) Meeting

On December 11, 2017 Alexion Pharmaceuticals, Inc. (NASDAQ:ALXN) reported the presentation of comprehensive dose-ranging data from two Phase 1b/2 studies of ALXN1210, the Company’s investigational long-acting C5 complement inhibitor, in patients with paroxysmal nocturnal hemoglobinuria (PNH), a chronic, progressive, debilitating and potentially life-threatening ultra-rare blood disorder characterized by complement-mediated hemolysis.1,2 Treatment with ALXN1210 for up to eight months resulted in rapid and sustained reduction of plasma lactate dehydrogenase (LDH) levels, a direct marker of hemolysis, with reductions in mean LDH levels from Baseline (BL) ranging from 73% to 88%. ALXN1210 was generally well tolerated with a safety profile that is consistent with that seen historically in patients with complement inhibition (Press release, Alexion, DEC 11, 2017, View Source [SID1234522523]). The data were presented at the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting & Exposition in Atlanta. All patients from the Phase 1b study and from Cohorts 1, 2, and 3 of the Phase 2 study have been successfully transitioned to the Phase 3 dosing regimen, after which plasma LDH levels have remained suppressed.

"It is encouraging to see rapid and sustained reduction in plasma LDH levels in these dose optimization studies," said Alexander Röth, M.D. from the Department of Hematology, West German Cancer Center, University Hospital Essen, Essen, Germany and an investigator in the Phase 1b/2 studies. "These comprehensive results provide robust preliminary evidence for the efficacy and safety of ALXN1210 as a future treatment for patients with PNH."

"The strength of these data and exposure-response analyses, along with the totality of data for ALXN1210 and discussions with global regulators, allowed us to determine an eight-week, weight-based dosing regimen that targets complete C5 inhibition and rapid and sustained suppression of LDH," said John Orloff, M.D., Executive Vice President and Head of Research & Development at Alexion. "We have completed enrollment in our two multinational Phase 3 PNH studies, with nearly 450 patients enrolled, and expect data from these studies in the second quarter of 2018."

Optimization of Dose Regimen for ALXN1210, a Novel Complement C5 Inhibitor, in Patients with Paroxysmal Nocturnal Hemoglobinuria (PNH): Results of Two Phase 1b/2 Studies 3

The researchers presented results from two open-label Phase 1b/2 studies designed to provide dose ranging data to optimize the dosing regimen for the Phase 3 development of ALXN1210 as a treatment for patients with PNH based on exposure-response assessments. The studies included a total of 39 adult patients with PNH (Study 103, n=13; Study 201, n=26) who were naïve to complement inhibition. The primary efficacy endpoint was the change from BL in mean plasma LDH levels to day 169 in Study 103 and day 253 in Study 201. The secondary efficacy endpoints were changes from BL in free hemoglobin, haptoglobin, and reticulocytes. Post hoc efficacy analyses evaluated the proportion of patients achieving LDH levels within the normal range and the incidence of breakthrough hemolysis (days 29-253). LDH BL was defined as the average of values at screening, prior to the first ALXN1210 infusion. For other parameters, BL was defined as the most recent value prior to the first infusion. Study 103 evaluated two escalating intravenous (IV) dosing regimens of ALXN1210, and Study 201 evaluated four IV regimens with different doses and intervals. The results demonstrated exposure-response relationships, and further substantiate and extend previously presented results.4,5,6,7

The most frequent related treatment-emergent adverse event (TEAE) was headache. No patient stopped treatment or withdrew from the studies, and there were no deaths. Two patients in Study 201 experienced meningococcal infections but recovered completely and continued receiving ALXN1210. Meningococcal infections are a known risk with terminal complement inhibition, and specific risk-management plans have been in place for ten years for Soliris (eculizumab) to minimize the risk for patients.

About Paroxysmal Nocturnal Hemoglobinuria (PNH)

Paroxysmal nocturnal hemoglobinuria (PNH) is a chronic, progressive, debilitating and potentially life-threatening ultra-rare blood disorder that can strike men and women of all races, backgrounds, and ages without warning, with an average age of onset in the early 30s.1,2,8 PNH often goes unrecognized, with delays in diagnosis ranging from one to more than 10 years.2 In patients with PNH, chronic, uncontrolled activation of the complement system, a component of the body’s immune system, results in hemolysis (the destruction of red blood cells)9, which in turn can result in progressive anemia, fatigue, dark urine and shortness of breath.10,11,12 The most devastating consequence of chronic hemolysis is thrombosis (the formation of blood clots), which can damage vital organs and cause premature death.13 Historically, it had been estimated that one in three patients with PNH did not survive more than five years from the time of diagnosis.2 PNH is more common among patients with disorders of the bone marrow, including aplastic anemia (AA) and myelodysplastic syndromes (MDS).14,15,16 In certain patients with thrombosis of unknown origin, PNH may be an underlying cause.9

About ALXN1210

ALXN1210 is an innovative, long-acting C5 inhibitor discovered and developed by Alexion that works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system that, when activated in an uncontrolled manner, plays a role in severe ultra-rare disorders like paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and anti-acetylcholine receptor (AchR) antibody-positive myasthenia gravis (MG). In early studies, ALXN1210 demonstrated rapid, complete, and sustained reduction of free C5 levels, as well as rapid and sustained reduction of plasma lactate dehydrogenase (LDH) levels, a direct marker of hemolysis (the destruction of red blood cells).4,5,6,7 ALXN1210 is currently being evaluated in Phase 3 clinical studies as a potential treatment for patients PNH and aHUS, administered intravenously every eight weeks. In addition, Alexion plans to initiate a single, pharmacokinetics (PK)-based Phase 3 clinical study of ALXN1210 delivered subcutaneously once per week as a potential treatment for patients with PNH and aHUS.

ALXN1210 has received Orphan Drug Designation (ODD) for the intravenous treatment of patients with PNH in the U.S. and EU, and for the subcutaneous treatment of patients with aHUS in the U.S.

About Soliris (eculizumab)

Soliris is a first-in-class complement inhibitor that works by inhibiting the C5 protein in the terminal part of the complement cascade, a part of the immune system that, when activated in an uncontrolled manner, plays a role in severe rare and ultra-rare disorders like paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and anti-acetylcholine receptor (AchR) antibody-positive myasthenia gravis (MG). Soliris is approved in the U.S., EU, Japan, and other countries as the first and only treatment for patients with PNH and aHUS, in the EU as the first and only treatment of refractory generalized MG (gMG) in adults who are anti-AchR antibody-positive, and in the U.S. for the treatment of adult patients with gMG who are anti-AchR antibody-positive. Alexion’s new drug application in Japan for Soliris as a treatment for patients with anti-AchR antibody-positive refractory gMG has been accepted for review by the Japanese Ministry of Health, Labour, and Welfare (MHLW). Soliris is not indicated for the treatment of patients with Shiga-toxin E. coli-related hemolytic uremic syndrome (STEC-HUS).

Soliris has received Orphan Drug Designation (ODD) for the treatment of patients with PNH in the U.S., EU, Japan, and many other countries, for the treatment of patients with aHUS in the U.S., EU, and many other countries, for the treatment of patients with MG in the U.S. and EU, and for the treatment of patients with refractory gMG in Japan. Alexion and Soliris have received some of the pharmaceutical industry’s highest honors for the medical innovation in complement inhibition: the Prix Galien USA (2008, Best Biotechnology Product) and France (2009, Rare Disease Treatment).

For more information on Soliris, please see full prescribing information for Soliris, including BOXED WARNING regarding risk of serious meningococcal infection, available at www.soliris.net

Important Soliris Safety Information

The U.S. prescribing information for Soliris includes the following warnings and precautions: Life-threatening and fatal meningococcal infections have occurred in patients treated with Soliris. Meningococcal infection may become rapidly life-threatening or fatal if not recognized and treated early. Comply with the most current Centers for Disease Control (CDC)’s Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients with complement deficiencies. Immunize patients with meningococcal vaccines at least two weeks prior to administering the first dose of Soliris, unless the risks of delaying Soliris therapy outweigh the risk of developing a meningococcal infection. Monitor patients for early signs of meningococcal infections and evaluate immediately if infection is suspected. Soliris is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Under the Soliris REMS, prescribers must enroll in the program. Enrollment in the Soliris REMS program and additional information are available by telephone: 1-888-SOLIRIS (1-888-765-4747) or at www.solirisrems.com.

Patients may have increased susceptibility to infections, especially with encapsulated bacteria. Aspergillus infections have occurred in immunocompromised and neutropenic patients. Children treated with Soliris may be at increased risk of developing serious infections due to Streptococcus pneumoniae and Haemophilus influenza type b (Hib). Soliris treatment of patients with PNH should not alter anticoagulant management because the effect of withdrawal of anticoagulant therapy during Soliris treatment has not been established. Administration of Soliris may result in infusion reactions, including anaphylaxis or other hypersensitivity reactions.

In patients with PNH, the most frequently reported adverse events observed with Soliris treatment in clinical studies were headache, nasopharyngitis, back pain and nausea. In patients with aHUS, the most frequently reported adverse events observed with Soliris treatment in clinical studies were headache, diarrhea, hypertension, upper respiratory infection, abdominal pain, vomiting, nasopharyngitis, anemia, cough, peripheral edema, nausea, urinary tract infections, and pyrexia. In patients with gMG who are anti-AchR antibody-positive, the most frequently reported adverse reaction observed with Soliris treatment in the placebo-controlled clinical study (≥10%) was musculoskeletal pain.

Astellas Announces First Clinical Data from Phase I Study of Gilteritinib in Combination with Intensive Chemotherapy in Patients Newly Diagnosed with Acute Myeloid Leukemia

On December 11, 2017 Astellas Pharma Inc. (TSE: 4503, President and CEO: Yoshihiko Hatanaka, "Astellas") reported the first data of the investigational agent gilteritinib from the ongoing, open-label, dose escalation/expansion Phase 1 study (NCT02236013) in newly diagnosed patients with acute myeloid leukemia (AML) (Press release, Astellas Pharma US, DEC 11, 2017, View Source [SID1234522546]). The data are being presented today in an oral presentation at the 2017 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting.

"These initial data shed encouraging light on the safety and tolerability of gilteritinib when combined with intensive chemotherapy for newly diagnosed AML patients," said Keith W. Pratz, M.D., of John Hopkins Sidney Kimmel Comprehensive Cancer Center, who is the principal investigator for the study. "In addition, while evaluating antitumor effects is an exploratory goal, the response rates in FLT3mut+ patients are promising and warrant expanded investigation of gilteritinib in this upfront treatment setting. Continuing research to evaluate the potential role for a FLT3 inhibitor in newly diagnosed patients and other stages of AML should continue to be a priority in our collective efforts to improve outcomes for patients."

The primary objective of this Phase 1 study is to assess the safety/tolerability profile, including dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD), of gilteritinib when combined with 7+3 induction (cytarabine and idarubicin) and high-dose cytarabine (HiDAC) consolidation chemotherapy, followed by single agent maintenance therapy in patients 18 years of age and older who have been newly diagnosed with AML. Assessment of antitumor effects of this combination therapy is an exploratory objective.

The two-part trial first enrolled patients to successive cohorts to determine the MTD. Successive cohorts received gilteritinib doses of 40, 80 or 120 mg/day. Dose escalation decisions were made based on DLTs that occurred following the first dose of gilteritinib during induction. Patients in the dose expansion cohort received gilteritinib at the recommended expansion dose established during dose escalation. Patients also received gilteritinib during consolidation, and then received maintenance therapy with once-daily gilteritinib over a 28-day cycle for up to 26 cycles.

"We are very encouraged by this initial data from our ongoing study of gilteritinib in combination with intensive chemotherapy in newly diagnosed AML patients, and pleased that it earned selection for oral presentation at ASH (Free ASH Whitepaper)," said Steven Benner, M.D., senior vice president and global therapeutic area head, Oncology Development, Astellas. "Mutations of FLT3 in AML are associated with a poor prognosis across the course of disease treatment and, through our comprehensive clinical development program, Astellas is committed to understanding how selective inhibition by gilteritinib might be beneficial to as many patients as possible."

As of July 9, 2017, 50 patients (n=17, dose escalation cohort; n=33, dose expansion cohort) had been enrolled in this ongoing study and 49 had received at least one dose of gilteritinib. Of the 48 patients with documented FLT3 mutation status, 23 (47.9%) were FLT3mut+, of whom 13 (56.5%) had internal tandem duplications (ITD).

Additional key findings include:

During dose escalation, two subjects in the 40 mg/day cohort who had received gilteritinib on days 1-14 experienced DLTs (neutropenia, thrombocytopenia and decreased ejection fraction). After gilteritinib induction schedule modification, no additional DLTs were observed.
The maximum tolerated dose was not reached; gilteritinib 120 mg/day was chosen as the recommended expansion dose.
Grade ≥ 3 treatment-emergent adverse events (TEAEs) occurring in ≥ 10% of subjects were febrile neutropenia (36.7%), thrombocytopenia (18.4%), neutropenia (16.3%) and decreased platelet count (12.2%).
Serious drug-related TEAEs occurring in >1 subject were febrile neutropenia (n=8), sepsis (n=2), small intestinal obstruction (n=2), lung infection (n=2), and decreased ejection fraction (n=2).
In FLT3mut+ and FLT3 wild type subjects, end-of-treatment CRc rates were 100% and 60.9%, respectively.
About Acute Myeloid Leukemia

Acute Myeloid Leukemia (AML) is a cancer that impacts the blood and bone marrow, and its incidence increases with age. The American Cancer Society estimates that in 2017, approximately 21,000 new patients will be diagnosed with AML in the United States and about 10,000 cases will result in death.

About Gilteritinib

Gilteritinib is an investigational compound that has demonstrated inhibitory activity against FLT3 internal tandem duplication (ITD) as well as FLT3 tyrosine kinase domain (TKD), two common types of FLT3 mutations that are seen in approximately one-third of patients with AML. Further, gilteritinib has also demonstrated inhibition of the AXL receptor in AML cell lines, which has been reported to be associated with therapeutic resistance. Astellas is currently investigating gilteritinib in various AML patient populations through several additional Phase 3 trials. Visit d to learn more about ongoing gilteritinib clinical trials.

Gilteritinib was discovered through a research collaboration with Kotobuki Pharmaceutical Co., Ltd., and Astellas has exclusive global rights to develop, manufacture and potentially commercialize gilteritinib. Gilteritinib has been granted Orphan Drug designation and Fast Track designation by the U.S. FDA, and SAKIGAKE designation by the Japan Ministry of Health, Labor and Welfare.

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.
