"Reducing the risk that muscle-invasive urothelial cancer will recur after surgery is very difficult, and we are disappointed that we were not able to significantly prolong disease-free survival," said Levi Garraway, M.D., Ph.D., Chief Medical Officer and Head of Global Product Development. "We remain committed to exploring the potential benefits of immunotherapy for more people with early cancers."

The goal in treating MIUC early is to reduce the risk of the disease recurring or spreading to other parts of the body. More treatment options following surgery are needed as approximately half of people with MIUC will develop a recurrence of their disease within 2 years of surgery.1

In addition to ongoing Phase III studies in early and advanced bladder cancer, Roche has an extensive development programme for Tecentriq, including multiple ongoing and planned Phase III studies across several types of lung, genitourinary, skin, breast, gastrointestinal, gynaecological, and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.

About the IMvigor010 study
IMvigor010 is a global Phase III, open-label, randomised, controlled study designed to evaluate the efficacy and safety of adjuvant treatment with Tecentriq compared to observation in 809 people with MIUC, who are at high risk for recurrence following resection. The primary endpoint is DFS as assessed by investigator, which is defined as the time from randomisation to invasive urothelial cancer recurrence or death.

About bladder cancer and muscle-invasive urothelial cancer
In 2018, there were over half a million new cases of bladder cancer diagnosed globally, with approximately 200,000 deaths from the disease.2 Urothelial cancer is the most common type of bladder cancer, accounting for about 90–95% of all cases.3 MIUC is a type of urothelial cancer that has spread into the muscle of the bladder, ureter or renal pelvis.4 Approximately 25% of new cases of bladder cancer are diagnosed with muscle-invasive disease,5 which is associated with a poorer prognosis than non-MIUC.4

About Tecentriq
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1, which is 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 is a cancer immunotherapy that has the potential to be used as a foundational combination partner with other immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers. The development of Tecentriq and its clinical programme is based on our greater understanding of how the immune system interacts with tumours and how harnessing a person’s immune system combats cancer more effectively.

Tecentriq is approved in the US, EU and countries around the world, either alone or in combination with targeted therapies and/or chemotherapies in various forms of non-small cell and small cell lung cancer, certain types of metastatic urothelial cancer, and in PD-L1-positive metastatic triple-negative breast cancer.

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.

By applying our seminal research in immune tumour profiling within the framework of the Roche-devised cancer immunity cycle, we are accelerating and expanding the transformative benefits with Tecentriq to a greater number of people living with cancer. Our cancer immunotherapy development programme takes a comprehensive approach in pursuing the goal of restoring cancer immunity to improve outcomes for patients.

CStone announces first patient dosed in the global proof-of-concept study of CS1001 in combination with Bayer’s regorafenib

On January 24, 2020 CStone Pharmaceuticals ("CStone" or the "Company", HKEX: 2616) reported that it has dosed the first patient in Australia in a clinical trial of CS1001, an investigational PD-L1 inhibitor developed by CStone, in combination with regorafenib, an oral multi-kinase inhibitor developed by Bayer Healthcare LLC ("Bayer") (Press release, CStone Pharmaceauticals, JAN 24, 2020, View Source [SID1234553543]). This is the first global proof-of-concept study carried out as a collaboration between CStone and Bayer. It is designed to assess the safety, tolerability, pharmacokinetics, and antitumor activity of the CS1001 plus regorafenib combination in patients with advanced solid tumors including gastric cancer, and to determine the recommended dose for subsequent studies.

CS1001 is an investigational anti-PD-L1 monoclonal antibody discovered by CStone. The drug candidate is being investigated in a number of clinical trials, including one Phase I bridging study in the U.S., one multi-arm Phase Ib study, two Phase II registrational studies and four Phase III studies in China for several tumor types. The Phase Ia/Ib results released at the 2019 Chinese Society of Clinical Oncology (CSCO) Annual Meeting have shown CS1001 to be well tolerated with promising antitumor activities across multiple cancers.

Developed by Bayer, regorafenib is an oral multi-kinase inhibitor that potently blocks protein kinases including VEGFR, FGFR, and CSF1R. Regorafenib has been approved in more than 90 countries, including China, for the second- or later-line treatment of patients with metastatic colorectal cancer, metastatic gastrointestinal stromal tumors, and advanced hepatocellular carcinoma.

In May 2019, CStone and Bayer entered into a global clinical collaboration in which CStone will sponsor clinical studies of the CS1001 in combination with regorafenib. Bayer will provide regorafenib for CStone-sponsored studies.

There is a large body of evidence demonstrating the clinical benefits of monotherapy with kinase inhibitor or anti-PD-1/L1 antibody in multiple malignancies. Preclinical studies revealed that targeted therapies such as regorafenib could bolster the efficacy of immune checkpoint inhibitors in select solid tumors through modulating the tumor immune microenvironment, implicating possible synergistic antitumor effects between the two mechanisms of action.

"Our collaboration with Bayer in this clinical program marks an important milestone in the implementation of CStone’s global strategy I am very pleased that the first patient has been dosed in this combination study.," said Dr. Frank Jiang, Chairman and CEO of CStone. "We hope this clinical program will strengthen CStone’s pipeline, and above all demonstrate the utility of this combination in improving the clinical outcomes for cancer patients who lack effective treatments."

"Preclinical studies in animal models have shown enhanced antitumor activity by the CS1001 plus regorafenib combination, lending evidential support to the design of this proof-of-concept study. In addition, a range of global studies of similar immuno-combination therapies have generated promising results in advanced or metastatic solid tumors," said Dr. Archie Tse, Chief Translational Medicine Officer at CStone. "We hope results from this trial will further validate the combination of multi-kinase inhibitors and immunotherapy in select tumors."

About Regorafenib (Stivarga)

Regorafenib is an oral multi-kinase inhibitor that potently blocks multiple protein kinases involved in tumor angiogenesis (VEGFR1, -2, -3, TIE2), oncogenesis (KIT, RET, RAF-1, BRAF), metastasis (VEGFR3, PDGFR, FGFR) and tumor immunity (CSF1R).

Regorafenib is a compound developed by Bayer. In 2011, Bayer entered into an agreement with Onyx, now an Amgen subsidiary, under which Onyx receives a royalty on all global net sales of regorafenib in oncology.

Regorafenib is approved under the brand name Stivarga in more than 90 countries worldwide, including the U.S., countries of the EU, China and Japan for the treatment of metastatic colorectal cancer (mCRC) and metastatic gastrointestinal stromal tumors (GIST) and second-line treatment of advanced hepatocellular (HCC).

About CS1001

CS1001 is an investigational monoclonal antibody directed against PD-L1 being developed by CStone. Authorized by the U.S. based Ligand Corporation, CS1001 is developed by the OMT transgenic animal platform, which can generate fully human antibodies in one step. As a fully human, full-length anti-PD-L1 monoclonal antibody, CS1001 mirrors natural G-type immune globulin 4 (IgG4) human antibody, which can reduce the risk of immunogenicity and potential toxicities in patients, potentially representing a unique advantage over similar drugs.

CS1001 has completed a Phase I dose-escalation study in China, in which CS1001 showed good tolerability and produced sustained clinical benefits during the Phase Ia stage of the study.

CS1001 is being investigated in a number of ongoing clinical trials, including one Phase I bridging study in the U.S., one multi-arm Phase Ib study, two Phase II registrational studies and four Phase III studies in China for several tumor types.

"The approval of TAZVERIK as a first-line therapy option for patients with unresectable metastatic or locally advanced epithelioid sarcoma is an important advancement in fighting this devastating disease"

"The approval of TAZVERIK as a first-line therapy option for patients with unresectable metastatic or locally advanced epithelioid sarcoma is an important advancement in fighting this devastating disease," said Paul Jardina, President and CEO, Onco360. "As a specialty pharmacy dedicated to serving people with cancer, Onco360 is honored to be selected as the exclusive specialty pharmacy partner for TAZVERIK. We are committed to improving the lives of patients suffering from epithelioid sarcoma."

Epithelioid sarcoma is a rare, slow-growing subtype of soft tissue sarcoma which occurs primarily in young adults. According to the National Comprehensive Cancer Network Guidelines, approximately 13,000 patients are diagnosed with soft tissue sarcomas annually, with a corresponding 5,100 deaths. Epithelioid sarcoma is believed to represent 1% of all soft tissue sarcoma diagnoses. Five-year overall survival ranges from 25-60% dependent upon tumor stage upon initial diagnosis. Greater than 90% of epithelioid sarcoma patients are found to have a genetic mutation, known as loss of INI-1 function, rendering them amenable to treatment with TAZVERIK, a novel EZH2 inhibitor.

TAZVERIK is manufactured by Epizyme, a global, commercial-stage, research-based biotechnology company, and was approved by the U.S. Food and Drug Administration (FDA) to treat adult and pediatric patients (aged 16 years and older) with metastatic or locally advanced epithelioid sarcoma not eligible for complete resection. The FDA’s approval of TAZVERIK is based on the results of an open-label, single-arm cohort of patients from the Phase II EZH-202 clinical trial (NCT02601950), which demonstrated a 15% overall rate of response. Prior to the approval of TAZVERIK, there were no medications that were specifically FDA-approved for the treatment of patients with epithelioid sarcoma.

CheckMate 040 is a phase 1/2 study that includes an exploratory cohort of patients with advanced HCC who were either treatment naïve (41%) or who were intolerant to or had progressed on prior sorafenib therapy (59%). For the 36 patients treated with the combination of cabozantinib and nivolumab (17 treatment naïve [47%] and 19 with prior sorafenib therapy [53%]), the investigator-assessed objective response rate (ORR) was 19%, and disease control rate (DCR) was 75%. Median progression-free survival (PFS) was 5.4 months, and median overall survival was 21.5 months. For the 35 patients treated with the combination of cabozantinib, nivolumab and ipilimumab (12 treatment naïve [34%] and 23 with prior sorafenib therapy [66%]), the investigator-assessed ORR was 29%, and DCR was 83%. Median PFS was 6.8 months, and median overall survival had not yet been reached.

"We are pleased to report clinically meaningful responses from CheckMate 040 cohort 6 in advanced liver cancer patients treated with these cabozantinib combinations," said Thomas Yau, M.D., Clinical Associate Professor, Department of Medicine, The University of Hong Kong, and a lead investigator of the trial. "Patients with advanced liver cancer need new and effective treatment options. Based on the cohort six findings, cabozantinib in combination with immunotherapy offers a potentially powerful and attractive new treatment approach that warrants further study in advanced liver cancer populations."

No new safety signals were identified in this combination cohort. Treatment-related grade 3 or 4 adverse events were observed in 47% of the cabozantinib and nivolumab group; events occurring in more than 5% of patients were hypertension (11%), diarrhea (11%), aspartate aminotransferase (AST) increase (8%) and lipase increase (6%). Treatment-related grade 3 or 4 adverse events were observed in 71% of the cabozantinib, nivolumab and ipilimumab group; events occurring in more than 5% of patients were AST increase (23%), lipase increase (17%), ALT increase (17%), hypertension (17%) and palmar-plantar erythrodysaesthesia (9%). Discontinuation rates due to treatment-related adverse events were 11% for the cabozantinib and nivolumab group and 20% for the cabozantinib, nivolumab and ipilimumab group.

"As we just marked one year since CABOMETYX was approved for the treatment of patients with advanced hepatocellular cancer who have previously received sorafenib, it’s exciting to be sharing new data featuring cabozantinib as part of a combination with immunotherapies," said Gisela Schwab, M.D., President, Product Development and Medical Affairs and Chief Medical Officer, Exelixis. "The promising clinical activity observed for these cohorts in CheckMate 040 suggests combination therapy with cabozantinib and immunotherapy may potentially benefit patients with this aggressive disease."

More information about this trial is available at ClinicalTrials.gov.
