PHILADELPHIA–(BUSINESS WIRE<\/a>)–
\nGSK plc (LSE\/NYSE: GSK) today announced the US Food and Drug Administration (FDA) has approved Jemperli <\/i>(dostarlimab-gxly) as the first and only immunotherapy for adults with stage II and III microsatellite instability-high (MSI-H)\/mismatch repair deficient (dMMR) locally advanced rectal cancer under the accelerated approval pathway.<\/p>\n\nCurrent standard of treatment for locally advanced rectal cancer includes chemotherapy, radiation and surgery1<\/sup>, but these can have lasting consequences, including bowel, urinary and sexual dysfunction, secondary cancers and infertility2,3<\/sup>. For patients with MSI-H\/dMMR tumors, a biomarker found in around 5-10% of rectal cancers4<\/sup>, Jemperli <\/i>monotherapy could help avoid these interventions.<\/p>\n
Tony Wood, Chief Scientific Officer, GSK, said: <\/b>\u201cToday, Jemperli <\/i>becomes the first and only approved immunotherapy for adults in the US with MSI-H\/dMMR locally advanced rectal cancer. For decades, treatment has relied on chemotherapy, radiation and surgery. This approval offers a new treatment approach and represents an important step towards more personalized care for these patients.\u201d<\/p>\n
Dr. Andrea Cercek, MD, Principal Investigator of AZUR-1, Section Head of Colorectal Cancer and Co-Director of the Center for Young Onset Colorectal and Gastrointestinal Cancer, Memorial Sloan Kettering Cancer Center, said: <\/b>\u201cThe AZUR-1 results demonstrate the potential for a fundamentally different treatment approach in this biomarker-defined patient population, and today\u2019s approval means MSI-H\/dMMR patients can now access a licensed treatment tailored to the biology of their disease.\u201d<\/p>\n
Michael Sapienza, CEO, Colorectal Cancer Alliance, said: <\/b>\u201cPeople facing rectal cancer are often thinking not only about treating their disease, but also worrying about what life will look like afterwards. The possibility of avoiding chemotherapy, radiation and surgery represents a meaningful advance for patients and their families. Biomarker testing at diagnosis will be essential to identifying patients who may be eligible for this treatment and helping them understand their options.\u201d<\/p>\n
\nApproval was based on data from the phase II AZUR-1 trial. The study met its primary objective, demonstrating a clinically significant proportion of participants achieved sustained clinical complete responses at 12 months (cCR12), with data continuing to mature.<\/p>\n
\nInvestigator-assessed data, a clinically relevant endpoint, showed 68% of evaluable patients (98\/144; 95% CI: 60%, 76%) achieved cCR12. In an exploratory analysis, 76% (110\/144; 95% CI: 69%, 83%) of evaluable patients had no evidence of cancer one year or more after treatment. This includes 68% (98\/144) (95% CI: 60%, 76%) of patients who reached cCR12 without surgery, plus other participants (n=12) who had their complete response confirmed through tissue analysis after surgery (pathological complete response, or pCR). No disease recurrences have been reported among responders to date, after a median follow up of more than two years.<\/p>\n
\nData on the primary objective, cCR12 assessed by Independent Central Review, continue to mature. 47% (54\/116) (95% CI: 37%, 56%) of evaluable patients have achieved cCR12. An additional 38 participants who are still progressing through to 12 month follow up have already achieved a clinical complete response.<\/p>\n
\nThe safety profile of Jemperli <\/i>was generally consistent with its established profile across solid tumors. Serious adverse reactions occurred in 20% of patients receiving Jemperli, <\/i>and the most common adverse reactions were fatigue (32%), rash (22%), diarrhea (18%) and pruritus (17%). Jemperli <\/i>was permanently discontinued due to adverse reactions in 3% of patients.<\/p>\n
\nFull data from the AZUR-1 interim analysis will be presented at the European Society for Medical Oncology (ESMO) Congress in October 2026.<\/p>\n
Jemperli <\/i>has received FDA Fast Track and Breakthrough Therapy designations for this indication. The application was also granted Priority Review and received a National Priority Voucher, resulting in an accelerated approval ahead of the PDUFA date.<\/p>\n
\nThe supplemental Biologics License Application (sBLA) is being reviewed under Project Orbis, an FDA Oncology Center of Excellence initiative that enables concurrent review by international health authorities. Regulatory reviews are ongoing in participating countries.<\/p>\n
About stage II\/III MSI-H\/dMMR locally advanced rectal cancer
\n
<\/b>Around 5\u201310% of rectal cancers are microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR)4<\/sup>. These tumors have a specific genetic characteristic where they are unable to properly repair DNA damage, leading to an accumulation of mutations. This unique biological feature often makes them highly responsive to immunotherapies like dostarlimab-gxly5,6<\/sup>. These biomarkers are commonly found in colorectal, endometrial and other gastrointestinal cancers, but can also be present in other solid tumors7<\/sup>.<\/p>\nAbout AZUR-1
\n
<\/b>AZUR-1 is a global, open-label, single-arm, registrational phase II trial evaluating dostarlimab-gxly monotherapy in patients (n=154) with previously untreated stage II and III MSI-H\/dMMR locally advanced rectal cancer. The trial was designed to assess clinical complete responses sustained for 12 months (cCR12) as determined by Independent Central Review, and to determine whether dostarlimab-gxly alone could enable patients to avoid chemotherapy, radiation and surgery. Additional efficacy outcomes include cCR12 based on investigator assessment and objective response rate (ORR), defined as patients who achieved cCR, clinical near-complete response, or clinical partial response as their best overall response. Patients received nine cycles of dostarlimab-gxly over six months, administered as a 500mg intravenous infusion every three weeks. The safety and tolerability profile of dostarlimab-gxly was generally consistent with its well-characterized safety profile observed across solid tumors. Serious adverse reactions occurred in 20% of patients receiving Jemperli <\/i>and treatment was permanently discontinued due to adverse reactions in 3% of patients. The most common adverse reactions (\u226515%) were fatigue, rash, diarrhea and pruritus.<\/p>\nAbout Jemperli<\/i>(dostarlimab-gxly)
\n
<\/b>Jemperli<\/i>, a programmed death receptor-1 (PD-1)-blocking antibody, plays an important role in GSK\u2019s immune-oncology research and development program. A robust clinical trial program includes studies of Jemperli <\/i>alone and in combination with other therapies in gynecologic, colorectal, and head and neck cancers, as well as where there are opportunities for transformational outcomes.<\/p>\nJemperli <\/i>was discovered by AnaptysBio, Inc. and licensed to TESARO, Inc., under a collaboration and exclusive license agreement signed in March 2014. Under this agreement, GSK is responsible for the ongoing research, development, commercialization and manufacturing of Jemperli<\/i>.<\/p>\n

For suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.<\/p>\n<\/li>\n
- \nBased on the severity of the adverse reaction, withhold or permanently discontinue JEMPERLI. In general, if JEMPERLI requires interruption or discontinuation, administer systemic corticosteroids (1 to 2 mg\/kg\/day prednisone or equivalent) until improvement to \u2264Grade 1. Upon improvement to \u2264Grade 1, initiate corticosteroid taper and continue to taper over at least 1 month.
