This represents a significant milestone and demonstrates <em>Jemperli</em>’s potential to redefine the treatment of cancers with high mortality rates and unmet needs, such as endometrial cancer,\" said <strong>Michelle Horn, Country Medical Director at GSK Canada</strong>. \"<em>Jemperli</em> remains a backbone of our immuno-oncology program, offering renewed hope to Canadian patients and emphasizing GSK's dedication, as a research-focused company, to addressing the most common gynaecologic cancer in Canada.\"</p>\n<p>Health Canada’s approval to expand the use of <em>Jemperli </em>is based on results from Part 1 of the RUBY phase III trial. RUBY Part 1 met its dual primary endpoints of Progression-Free Survival (PFS) and Overall Survival (OS) in the overall population of patients with primary advanced or recurrent endometrial cancer, and is the only clinical trial in this setting to show a clinically meaningful and statistically significant OS benefit, demonstrating a 31% reduction in risk of death (HR: 0.69; 95% CI: 0.54–0.89, p=0.002, n=494) compared to chemotherapy alone.</p>\n<p>\"Gynaecological oncologists have long awaited an immuno-oncology option to improve survival outcomes for endometrial cancer patients at advanced stages, and newly approved treatments in Canada enhance the cancer care journey by offering more personalized options,\" says <strong>Dr. Alon Altman,</strong> <strong>Gynecologic Oncologist and Professor of Obstetrics and Gynecology at the University of Manitoba, and Chief Strategy Officer and Former President of The Society of Gynecologic Oncology of Canada (GOC)</strong>. \"Ensuring innovative clinical therapies are publicly available and accessible to all patients in need is also vital as timely treatment is especially crucial for individuals with more advanced endometrial cancer who cannot afford to wait.\"</p>\n<p>The expanded approval follows <em>Jemperli’s</em> November 2023 approval in combination with carboplatin and paclitaxel for the treatment of adult patients with primary advanced or recurrent mismatch repair deficient (dMMR)/ microsatellite instability-high (MSI-H) endometrial cancer who are candidates for systemic therapy, based on an earlier analysis of Part 1 of the RUBY study.</p>\n<p><strong>Filomena Servidio-Italiano, President &amp; CEO of the Colorectal Cancer Resource &amp; Action Network (CCRAN)</strong>, a patient advocacy group dedicated to improving the longevity and quality of life for all cancer patients in Canada, stated, “The expanded approval of dostarlimab provides patients with advanced or recurrent endometrial cancer new hope of extending their lives. Patients and advocates should be encouraged by this announcement, offering a new treatment option to patients in Canada diagnosed with endometrial cancer. We are optimistic that the Canadian reimbursement and funding systems will support the accessibility of this important therapy for those in need.\"</p>\n<p><strong>About endometrial cancer </strong></p>\n<p>Endometrial cancer is found in the inner lining of the uterus, known as the endometrium. Endometrial cancer is the most common gynaecologic cancer in developed countries,<sup>[3]</sup> with an estimated 1.6 million people living with active disease at any stage and 417,000 new cases reported each year worldwide.<sup>[4] </sup>Incidence rates are expected to rise by approximately 40% between 2020 and 2040.<sup>[5]</sup> In Canada, an estimated 8,600 women were diagnosed with endometrial cancer in 2024, with approximately 1,600 succumbing to the disease.<sup>[6]</sup> Approximately 15-20% of patients with endometrial cancer will be diagnosed with advanced disease at the time of diagnosis.<sup>[7]</sup> Among patients with primary advanced or recurrent endometrial cancer, approximately 75% have MMRp/MSS tumours.<sup>[2]</sup></p>\n<p><strong>About RUBY</strong></p>\n<p>RUBY is a two-part global, randomized, double-blind, multicentre phase III trial of patients with primary advanced or recurrent endometrial cancer. Part 1 evaluated dostarlimab plus carboplatin-paclitaxel followed by dostarlimab versus carboplatin-paclitaxel plus placebo followed by placebo.</p>\n<p>In Part 1, the dual-primary endpoints are investigator-assessed PFS based on the Response Evaluation Criteria in Solid Tumours v1.1, and OS. The statistical analysis plan included pre-specified analyses of PFS in the dMMR/ MSI-H and overall populations and OS in the overall population. Pre-specified exploratory analyses of PFS and OS in the MMRp/MSS population and OS in the dMMR/MSI-H populations were also performed. RUBY Part 1 included 494 patients in efficacy analyses across a broad population, including histologies often excluded from clinical trials (approximately 10% of patients with carcinosarcoma and 20% with serous carcinoma).</p>\n<p><strong>About <em>Jemperli </em>(dostarlimab for injection)</strong></p>\n<p><em>Jemperli</em> is a programmed death receptor-1 (PD-1)-blocking antibody that binds to the PD-1 receptor and blocks its interaction with the PD-1 ligands PD-L1 and PD-L2.<sup>[8]</sup></p>\n<p>In Canada, <em>Jemperli</em> (dostarlimab for injection) is indicated in combination with carboplatin and paclitaxel for the treatment of adult patients with primary advanced or first recurrent endometrial cancer who are candidates for systemic therapy which includes patients with MMRp/MSS and dMMR/MSI-H tumours. <em>Jemperli</em> is also approved as monotherapy for the treatment of adult patients with dMMR/MSI-H recurrent or advanced endometrial cancer that has progressed on or following prior treatment with a platinum-containing regimen.</p>\n<p>Please consult the <a href=\"/en-ca/products/jemperli/\" title=\"JEMPERLI\"><strong>Product Monograph</strong></a> at <strong>www.gsk.ca</strong> for complete safety information.
