Longest survival follow-up ever reported for a Phase III immunotherapy trial in this setting WILMINGTON, DE, USA I September 16, 2024 I Updated results from the HIMALAYA Phase III trial showed AstraZeneca’s IMFINZI ® (durvalumab) plus IMJUDO ® (tremelimumab-actl) demonstrated a sustained, clinically meaningful overall survival (OS) benefit at five years for patients with unresectable hepatocellular carcinoma (HCC) who had not received prior systemic therapy and were not eligible for localized treatment. These results from HIMALAYA will be presented today at the European Society for Medical Oncology (ESMO) Congress 2024 in Barcelona, Spain (presentation 947MO). At five years of follow-up, this latest exploratory analysis showed that a single priming dose of IMJUDO added toIMFINZI, called the STRIDE regimen (Single Tremelimumab-actl Regular Interval Durvalumab), reduced the risk of death by 24% compared to sorafenib (based on a hazard ratio [HR] of 0.76; 95% confidence interval [CI] 0.65-0.89). An estimated 19.6% of patients treated with the STRIDE regimen were alive at five years versus 9.4% for those treated with sorafenib. In a subgroup analysis of patients in the trial who achieved disease control, defined as complete or partial response or stable disease, 28.7% of those treated with the STRIDE regimen were alive at five years versus 12.7% of patients treated with sorafenib. In addition, an exploratory analysis of depth of response (DpR) showed that more patients treated with the STRIDE regimen experienced deep responses leading to longer survival compared to sorafenib. Lorenza Rimassa, MD, Associate Professor of Medical Oncology, Humanitas University and IRCCS Humanitas Research Hospital, Milan, Italy and a lead investigator in the HIMALAYA trial, said: “Treatment with durvalumab plus tremelimumab-actl for patients with advanced liver cancer doubled the overall survival rate at five years, a significant survival advantage over sorafenib that has also become even more pronounced over time. These data reinforce the use of this novel dual immunotherapy regimen and are an important milestone for patients with this devastating disease.” Sarah Manes, Liver Cancers Program Director at Global Liver Institute, said: “Reaching the five-year survival milestone is both clinically significant and emotionally meaningful for people with advanced liver cancer and their families. We are thrilled to see this progress in improving outcomes with new treatment options, bringing new hope for long-term survivorship to patients in our community.” Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “It is remarkable to see nearly 20 percent of patients with advanced liver cancer treated with the STRIDE regimen alive at five years compared to only about seven percent of patients living that long historically. This is a major step forward, setting a new survival benchmark. This underscores our commitment to following patients for the long term to help us better characterize the enduring clinical benefits of this innovative priming approach with an anti-CTLA-4 antibody added to PD-L1 blockade.” Summary of updated survival results: HIMALAYA The safety profile of the STRIDE regimen was consistent with the known profiles of each medicine, and no new safety signals were observed with longer follow-up. Serious treatment-related adverse events, defined as Grade 3 or 4 and including death, were experienced by 17.5% of patients treated with the STRIDE regimen versus 9.9% of patients treated with sorafenib, with no new events occurring after the primary analysis for STRIDE. IMFINZI in combination with IMJUDO is approved for the treatment of adults with advanced or unresectable HCC in the US, EU (in the 1st-line setting), Japan and several other countries. IMFINZI monotherapy is also approved in Japan in this setting. IMFINZI is indicated for the treatment of adult patients with unresectable Stage III non-small cell lung cancer (NSCLC) whose disease has not progressed following concurrent platinum-based chemotherapy and radiation therapy. IMFINZI, in combination with IMJUDO and platinum-based chemotherapy, is indicated for the treatment of adult patients with metastatic NSCLC with no sensitizing epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) genomic tumor aberrations. IMFINZI, in combination with etoposide and either carboplatin or cisplatin, is indicated for the first-line treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC). IMFINZI, in combination with gemcitabine and cisplatin, is indicated for the treatment of adult patients with locally advanced or metastatic biliary tract cancer (BTC). IMFINZI in combination with IMJUDO is indicated for the treatment of adult patients with unresectable hepatocellular carcinoma (uHCC). IMFINZI in combination with carboplatin and paclitaxel followed by IMFINZI as a single agent is indicated for the treatment of adult patients with primary advanced or recurrent endometrial cancer that is mismatch repair deficient (dMMR). Please see Full Prescribing Information including Medication Guide for IMFINZI and IMJUDO . Notes Liver cancer Liver cancer, of which HCC is the most common type, is the third-leading cause of cancer death, with nearly 900,000 people worldwide diagnosed each year and a high prevalence in certain regions of Asia. 1-2 An estimated 80-90% of all patients with HCC also have cirrhosis. Chronic liver diseases such as cirrhosis are associated with inflammation that over time can lead to the development of HCC. 3 Advanced-stage HCC prognosis is poor, with a five-year survival rate of only 7%. 4 More than half of patients are diagnosed at advanced stages of the disease, often when symptoms first appear. 5 The unique immune environment of liver cancer provides clear rationale for investigating medications that harness the power of the immune system to treat HCC. 5 HIMALAYA HIMALAYA is a randomized, open-label, multi-center, global Phase III trial of IMFINZI monotherapy and a regimen comprising a single priming dose of IMJUDO 300 mg added to IMFINZI1500mg followed by IMFINZIevery four weeks (STRIDE regimen) versus sorafenib, a standard-of-care multi-kinase inhibitor. The trial included a total of 1,324 randomized patients with unresectable, advanced HCC who had not been treated with prior systemic therapy and were not eligible for locoregional therapy (treatment localized to the liver and surrounding tissue). The trial was conducted in 181 centers across 16 countries, including in the US, Canada, Europe, South America and Asia. The primary endpoint was OS for the combination versus sorafenib and key secondary endpoints included OS for IMFINZIversus sorafenib, objective response rate and progression-free survival (PFS) for the combination and for IMFINZIalone. IMFINZI IMFINZI ® (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor’s immune-evading tactics and releasing the inhibition of immune responses. IMFINZI is approved in combination with chemotherapy (gemcitabine plus cisplatin) in locally advanced or metastatic biliary tract cancer (BTC) and in combination with IMJUDO ® (tremelimumab-actl) in unresectable HCC. IMFINZI is also approved as a monotherapy in unresectable HCC in Japan and the EU and in combination with chemotherapy (carboplatin plus paclitaxel) followed by IMFINZI monotherapy in primary advanced or recurrent endometrial cancer that is mismatch repair deficient in the US. In addition to its indications in gastrointestinal (GI) cancers, IMFINZI is the global standard of care in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiotherapy. IMFINZI is also approved for the treatment of extensive-stage small cell lung cancer (SCLC) and in combination with a short course of IMJUDO and chemotherapy for the treatment of metastatic NSCLC. In limited-stage SCLC, IMFINZI demonstrated statistically significant and clinically meaningful improvements in the dual primary endpoints of OS and PFS compared to placebo in patients who had not progressed following standard-of-care concurrent chemoradiotherapy in the ADRIATIC Phase III trial. IMFINZI in combination with neoadjuvant platinum-containing chemotherapy before surgery and as adjuvant monotherapy after surgery has been approved for patients in the US and several other countries for the treatment of adult patients with resectable NSCLC and no known epidermal growth factor receptor mutations or anaplastic lymphoma kinase rearrangements. IMFINZI plus chemotherapy followed by IMFINZI alone was recently approved in the US for mismatch repair deficient patients with primary advanced or recurrent endometrial cancer. This regimen was also approved in the EU, in addition to IMFINZI plus chemotherapy followed by IMFINZI and olaparib for mismatch repair proficient patients. In muscle-invasive bladder cancer, IMFINZI in combination with chemotherapy demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of event-free survival and the key secondary endpoint of OS versus neoadjuvant chemotherapy in the NIAGARA Phase III trial. Since the first approval in May 2017, more than 220,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with SCLC, NSCLC, bladder cancer, breast cancer, several GI and gynecologic cancers other solid tumors. IMJUDO IMJUDO ® (tremelimumab-actl) is a human monoclonal antibody that targets the activity of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). IMJUDO blocks the activity of CTLA-4, contributing to T-cell activation, priming the immune response to cancer and fostering cancer cell death. In addition to its approved indications in liver and lung cancers, IMJUDOis being tested in combination with IMFINZI across multiple tumor types including locoregional HCC (EMERALD-3), SCLC (ADRIATIC) and bladder cancer (VOLGA and NILE). AstraZeneca in GI cancers AstraZeneca has a broad development program for the treatment of GI cancers across several medicines and a variety of tumor types and stages of disease. In 2022, GI cancers collectively represented approximately 4.9 million new cancer cases leading to approximately 3.3 million deaths. 6 Within this program, the Company is committed to improving outcomes in gastric, liver, biliary tract, esophageal, pancreatic and colorectal cancers. In addition to its indications in BTC and HCC, IMFINZI is being assessed in combinations, including with IMJUDO, in liver, esophageal and gastric cancers in an extensive development program spanning early to late-stage disease across settings. The Company is also assessing rilvegostomig (AZD2936), a PD-1/TIGIT bispecific antibody, in combination with chemotherapy as an adjuvant therapy in BTC and as a 1st-line treatment in patients with HER2-negative, locally advanced unresectable or metastatic gastroesophageal junction cancers. Fam-trastuzumab deruxtecan-nxki, a HER2-directed antibody drug conjugate, is approved in the US, China and several other countries for HER2-positive advanced gastric cancer and is being assessed in colorectal cancer. It also has been assessed in multiple GI settings including BTC in the DESTINY-PanTumor02 Phase II trial, and it was recently approved in the US for the treatment of unresectable or metastatic HER2-positive solid tumors who have received prior systemic treatment and have no satisfactory alternative treatment options. Fam-trastuzumab deruxtecan-nxki is jointly developed and commercialized by AstraZeneca and Daiichi Sankyo.
