"We are pleased to present positive Patient-Reported Outcomes data from the Phase III IMmotion151 study, which demonstrate the quality of life benefits that TECENTRIQ and Avastin potentially bring to people living with advanced kidney cancer," said Sandra Horning, M.D., Chief Medical Officer and Head of Global Product Development. "We will also present promising early data for TECENTRIQ and Avastin in advanced or metastatic liver cancer, where there is a significant need for new therapies. Data from these two studies provide further evidence to support the potential of this unique combination across multiple settings."

Patient-Reported Outcome (PRO) collected in the Phase III IMmotion151 study investigating the combination of TECENTRIQ and Avastin as a first-line treatment for mRCC, compared with a current standard of care sunitinib, were evaluated in the overall study population and show:

Patients receiving the combination reported a better health-related quality of life (HRQol) overall when compared with sunitinib. HRQol evaluates the overall impact of disease and treatment on patient’s quality of life in terms of disease related symptoms, treatment side effects and function/well-being
Patients receiving the combination reported lower impact of symptoms on day-to-day life, when compared with patients receiving sunitinib
The combination of TECENTRIQ and Avastin markedly increased the time before symptoms meaningfully impacted day-to-day life compared to sunitinib (median time to deterioration: 11.3 vs 4.3 months; HR=0.56; 95% CI: 0.46, 0.68)
Patients receiving the combination had milder and more stable symptom severity overall and a clinically meaningful reduction in the five most severe disease symptoms
Patients completed questionnaires on Days 1 and 22 of each 6-week cycle, at the end of treatment
Earlier this year, Roche announced that IMmotion151 met its co-primary endpoint of investigator-assessed progression-free survival (PFS) when comparing the TECENTRIQ and Avastin combination with sunitinib for people whose disease expressed the PD-L1 (programmed death-ligand 1) protein. The safety profile was consistent with previously reported data, with a discontinuation of the combination regimen only occurring in 5% of the patients and a lower rate of Grade 3-4 treatment-related adverse events with the TECENTRIQ and Avastin combination (40%) than with sunitinib alone (54%). 16% of patients required use of systemic steroids within 30 days of the onset of an immune-related AE.

Further data for TECENTRIQ and Avastin will be presented from an ongoing Phase Ib study evaluating the combination as a first-line treatment in untreated advanced, unresectable or metastatic HCC. In the safety evaluable population (n=43), 28% patients (n=12) experienced Grade 3-4 treatment-related adverse events and no treatment-related Grade 5 adverse events were observed. No new safety signals were identified beyond the established safety profiles for the individual medicines. After a median follow-up of 10.3 months, responses (investigator assessed per RECIST v1.1) were seen in 14 (61%) of 23 efficacy evaluable patients and regardless of disease etiology (cause), region (Asia or US), baseline alpha-fetoprotein levels or spread of tumour beyond the liver. Assessment by independent review facility (IRF) assessed per RECIST v1.1 revealed a response rate of 65% (15 out of 23 patients). Median progression free survival (PFS), duration of response (DOR), time to progression (TTP) and overall survival (OS) have not yet been reached after a median follow-up of 10.3 months; results will be presented at a future medical congress when updated data from an expanded cohort are available. A larger randomised Phase III study in untreated locally advanced or metastatic HCC, IMbrave150, evaluating the combination of TECENTRIQ and Avastin versus the standard of care sorafenib, is underway and recruiting patients.

In early stage bladder cancer, results from an interim analysis of a Phase II investigator-initiated study (ABACUS) evaluating neoadjuvant TECENTRIQ monotherapy in 68 evaluable patients with muscle invasive disease will also be presented. Topline results demonstrated a clinically meaningful pathological complete response (pCR) rate of 18 / 62 (29%). Of the pCR patients, 17% had pT3/4 disease at baseline. Treatment-related Grade 3-4 adverse events occurred in 12% of patients while Grade 3-4 surgical complications occurred in 31% of patients. The trial aims to test the efficacy of preoperative TECENTRIQ and includes extensive biomarker work on samples from these patients.

The results of the three studies will be presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting on Sunday 3 June 2018.

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 (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. Secondary endpoints included OS in people whose tumours expressed PD-L1, PFS as determined by an Independent Review Facility (IRF) according to RECIST v1.1, investigator-assessed objective response rate (ORR) and duration of response (DOR), change from baseline in symptom interference and symptom severity as determined by M.D. Anderson Symptom Inventory (MDASI), and change from baseline in health-related quality of life as determined by European Quality of Life 5-Dimension (EQ-5D) Scores. PROs were evaluated as secondary and exploratory endpoints to document patient perspective on overall clinical benefit for each treatment.

About the Phase Ib study in HCC (NCT02715531)
This Phase Ib study evaluates the safety and clinical activity of the combination of TECENTRIQ and Avastin in people with untreated advanced, unresectable or metastatic HCC. Patients received TECENTRIQ (1200 mg) + Avastin (15 mg/kg) IV every 3 weeks until loss of clinical benefit or unacceptable toxicity. The primary objective was to assess the safety and tolerability as well as the efficacy of the combination. The primary efficacy endpoint is investigator-assessed objective response rate (ORR). Secondary efficacy endpoints include progression-free survival (PFS), duration of response (DOR) and time to progression (TTP) per RECIST v1.1; as well as overall survival (OS).

About IMbrave150
IMbrave150 is a Phase III, multicentre, randomised open-label study randomising approximately 480 patients with untreated advanced, unresectable or metastatic hepatocellular carcinoma 2:1 to receive TECENTRIQ in combination with Avastin or sorafenib. TECENTRIQ will be administered by IV, 1200mg on day 1 of each 21 day cycle and Avastin will be administered by IV, 15mg/kg on day 1 of each 21 day cycle. Sorafenib will be administered by mouth, 400mg twice per day, on days 1-21 of each 21 day cycle. Patients will receive the combination and the control arm until unacceptable toxicity or loss of clinical benefit as determined by the investigator. Co-primary endpoints are overall survival and investigator-assessed objective response rate. Secondary endpoints include progression free survival (PFS), time to progression (TTP), duration of response (DOR) and independent review facility (IRF) assessed responses.

About the ABACUS study
ABACUS is an investigator-initiated, open-label, international, multicentre, phase II trial for patients with histologically confirmed (T2-T4a) transitional cell carcinoma of the bladder. The trial aims to test the efficacy of preoperative TECENTRIQ and includes extensive biomarker work on samples from these patients. Patients received two 3-weekly cycles of TECENTRIQ prior to cystectomy. Following cystectomy, patients were followed up for safety, survival, and disease data. Co-primary endpoints are (1) efficacy of atezolizumab prior to cystectomy assessed as pathological complete response rate and (2) immune parameters. Secondary endpoints include safety and efficacy based on anti-tumour effect by radiological response.

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 70 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 the TECENTRIQ (atezolizumab) and Avastin (bevacizumab) combination
There is a strong scientific rationale to support combining TECENTRIQ and Avastin. The TECENTRIQ and Avastin regimen may enhance the potential of the immune system to combat a broad range of cancers. 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 renal cell carcinoma
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.3

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.5

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

About hepatocellular carcinoma
HCC is the most common primary malignancy of the liver and has a very high fatality rate.6 Globally, it’s the fifth most common cancer in men and the seventh most common cancer among women, with over half a million new cases diagnosed annually.6 HCC develops predominantly in those patients with cirrhosis due to chronic hepatitis B or C,6 and typically presents at an advanced stage where there are limited treatment options.7

About urothelial carcinoma
Bladder cancer is the ninth most common cancer worldwide, with 430,000 new cases diagnosed in 2012, and it results in approximately 165,000 deaths globally each year. Men are three times more likely to suffer from bladder cancer, compared with women,8 and the disease is three times more common in developed countries than in less developed countries.9 There are three types of bladder cancer: transitional cell carcinoma (which begins in cells in the innermost tissue layer), squamous cell carcinoma (which begins in squamous cells) and adenocarcinoma (which begins in glandular cells in the lining of the bladder). Most cancers that form in the bladder are transitional cell carcinomas.10

European Commission approves Roche’s Perjeta for post-surgery treatment of HER2-positive early breast cancer at high risk of recurrence

On June 1, 2018 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the European Commission (EC) has approved Perjeta (pertuzumab) in combination with Herceptin (trastuzumab) and chemotherapy (the Perjeta-based regimen) for post-surgery (adjuvant) treatment of adult patients with HER2-positive early breast cancer (eBC) at high risk of recurrence (Press release, Hoffmann-La Roche, JUN 1, 2018, View Source [SID1234527039]). High risk of recurrence is defined as lymph node-positive or hormone receptor-negative disease. The Perjeta-based regimen should be administered for a total of one year (up to 18 cycles) as part of a complete regimen for eBC and regardless of the timing of surgery.

HER2-positive breast cancer affects almost 100,000 women in Europe each year.1,2 The majority of these cases are diagnosed at an early stage, when the aim of treatment is cure.3,4 While significant advances have been made in treating HER2-positive eBC, around one in four patients treated with Herceptin and chemotherapy will eventually see their disease return in the long-term.5 It is estimated that two out of three cases of HER2-positive advanced breast cancer (aBC) are a result of recurrence, as opposed to aBC being the initial diagnosis.6 There is no cure for breast cancer that recurs and reaches an advanced stage; in these cases, treatment is aimed at prolonging life for as long as possible.7

"Despite advances in the treatment of HER2-positive early breast cancer, many people still have a recurrence and progress to an incurable stage. In the early breast cancer setting, where the ultimate goal is cure, it is critical that we continue building on existing therapies," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "Today’s approval is great news, as we believe the Perjeta-based regimen has the potential to make a significant impact on the lives of people with HER2-positive early breast cancer who are at high risk of recurrence. We are committed to working with EU member states to ensure the Perjeta-based regimen is available to eligible patients as soon as possible."

"Some patients with early HER2-positive breast cancer are more likely to relapse than others, despite available treatments. Perjeta builds on the efficacy we have already seen with Herceptin and provides a clinically meaningful reduction in the risk of the breast cancer returning or death, for patients at high risk of recurrence," explained José Baselga, MD, PhD, Physician-in-Chief, Memorial Hospital, Memorial Sloan Kettering Cancer Center. "The only setting where we can potentially cure HER2-positive breast cancer is at the early stage, so the availability of new treatment options is great news for patients."

The EC approval is based on results from a large phase III study (APHINITY), involving over 4,800 people with HER2-positive eBC8, which showed that the Perjeta-based regimen significantly reduced the risk of invasive breast cancer recurrence or death (invasive disease-free survival, iDFS) compared to Herceptin and chemotherapy alone in the overall study population.8 At the time of primary analysis, the Perjeta-based regimen showed the greatest benefit in certain patients who are at high risk of recurrence:8

For patients with lymph node-positive disease, the risk of recurrence or death was reduced by 23% with the Perjeta-based regimen (HR=0.77; 95% CI 0.62-0.96, p=0.019).*
Among patients with hormone receptor-negative disease, the Perjeta-based regimen reduced the risk of recurrence or death by 24% (HR=0.76; 95% CI 0.56-1.04, p=0.085).*
The safety profile of the Perjeta-based regimen was consistent with that seen in previous studies, with a low incidence of cardiac events and no new safety signals.8

In the eBC setting, treatment may be given before surgery (neoadjuvant treatment) to shrink tumours and after surgery (adjuvant treatment) to help prevent the cancer from returning.9 The Perjeta-based regimen is already licensed in the EU, US and many other countries as a neoadjuvant treatment.10,11 The adjuvant approval means that eligible patients with HER2-positive eBC in Europe should be treated with the Perjeta-based regimen for a total of one year as part of a complete regimen for eBC, regardless of the timing of surgery. The Perjeta-based regimen is already approved in the US and several other countries for adjuvant treatment of HER2-positive eBC at high risk of recurrence.10

The combination has also been previously approved for the treatment of people with advanced HER2-positive breast cancer, where it has been shown to significantly extend survival compared to Herceptin and chemotherapy alone.10,11

On 30 April, the EC also approved the use of Perjeta with a subcutaneous (SC) formulation of Herceptin as an alternative to the previously approved co-administration of Perjeta with Herceptin intravenous (IV) formulation.11 The Herceptin SC formulation allows Herceptin to be delivered to patients in two to five minutes via an injection under the skin, compared to 30 to 90 minutes required for the original IV formulation.12

Perjeta works in combination with Herceptin to provide a more comprehensive, dual blockade of the HER2 receptor, thus preventing tumour cell growth and survival.13

About APHINITY8
APHINITY (Adjuvant Pertuzumab and Herceptin IN Initial TherapY in Breast Cancer, NCT01358877/ BO25126/ BIG 4-11) is an international, phase III, randomised, double-blind, placebo-controlled, two-arm study evaluating the efficacy and safety of Perjeta plus Herceptin and chemotherapy, compared to Herceptin and chemotherapy, as adjuvant therapy in 4,805 people with operable HER2-positive eBC. The primary efficacy endpoint of the APHINITY study is invasive disease-free survival (iDFS), which in this study is defined as the time a patient lives without return of invasive breast cancer at any site or death from any cause after adjuvant treatment. Secondary endpoints include cardiac and overall safety, overall survival, disease-free survival and health-related quality of life. The study will continue to follow participants for ten years.

At the time of the primary analysis, with a median follow-up of 45.4 months, the Perjeta-based regimen significantly reduced the risk of invasive breast cancer recurrence or death by 19% compared to Herceptin and chemotherapy alone in the overall study population (HR=0.81, 95% CI 0.66-1.00, p=0.045). Estimates of iDFS rates were 94.1% vs. 93.2% at three years and 92.3% vs. 90.6% at four years† in Perjeta-treated patients vs. placebo-treated patients, respectively.

The subgroup results were as follows:

Lymph node-positive subgroup (HR=0.77, 95% CI 0.62-0.96)*
Estimate of iDFS at three years 92.0% vs. 90.2%
Estimate of iDFS at four years 89.9% vs. 86.7%†
Lymph node-negative subgroup (HR=1.13, 95% CI 0.68-1.86)*
Estimate of iDFS at three years 97.5% vs. 98.4%
Estimate of iDFS at four years 96.2% vs. 96.7%†
Hormone receptor-negative subgroup (HR=0.76, 95% CI 0.56-1.04)*
Estimate of iDFS at three years 92.8% vs. 91.2%
Estimate of iDFS at four years 91.0% vs. 88.7%†
Hormone receptor-positive subgroup (HR=0.86, 95% CI 0.66-1.13)*
Estimate of iDFS at three years 94.8% vs. 94.4%
Estimate of iDFS at four years 93.0% vs. 91.6%†
The most common severe (Grade 3-4) side effects with the Perjeta-based regimen are low levels of white blood cells with or without a fever, diarrhoea, decrease in certain types of white blood cells, decrease in red blood cells, fatigue, nausea and mouth blisters or sores. The most common side effects are diarrhoea, nausea, hair loss, fatigue, nerve damage and vomiting.

* Prespecified subgroup analyses without adjusting for multiple comparisons. Results are considered descriptive.

† iDFS at four years was calculated based on data available at the time of primary analysis with median follow-up of 45.4 months.

About Perjeta
Perjeta is a medicine that targets the HER2 receptor, a protein found on the outside of many normal cells and in high quantities on the outside of cancer cells in HER2-positive cancers.14,15 Perjeta is designed specifically to prevent the HER2 receptor from pairing (or ‘dimerising’) with other HER receptors (EGFR/HER1, HER3 and HER4) on the surface of cells, a process that is believed to play a role in tumour growth and survival. Binding of Perjeta to HER2 may also signal the body’s immune system to destroy the cancer cells. The mechanisms of action of Perjeta and Herceptin are believed to complement each other, as both bind to the HER2 receptor, but to different places. The combination of Perjeta and Herceptin is thought to provide a more comprehensive, dual blockade of HER signalling pathways, thus preventing tumour cell growth and survival.13,16
