Nogapendekin alfa inbakicept-pmln

CULVER CITY, Calif.--( BUSINESS WIRE )--Immunotherapy innovator ImmunityBio, Inc. ( NASDAQ: IBRX ), today announced positive results from its QUILT 3.055 trial demonstrating long-term extended survival of 14 months to as much as five years for patients with advanced non-small cell lung cancer (NSCLC) being treated with checkpoint inhibitors (CPI). An oral presentation of the data was presented by John Wrangle, M.D., MPH, Associate Professor, Medical University of South Carolina, at the World Congress on Lung Cancer in San Diego on Sunday, September 8 in the session titled “Novel Immunotherapy Strategies and Combinations.” The phase 2b study of ANKTIVA (nogapendekin alfa inbakicept-pmln) in combination with checkpoint inhibitors KEYTRUDA or OPDIVO in multiple tumor types including NSCLC who failed CPI showed long-term overall survival of 57 percent (49/86) and 34 percent (29/86) at 12 and 18 months respectively, exceeding the current standard of care. “Most NSCLC patients experience progression following checkpoint inhibitors, with average survival well under a year when checkpoint inhibitor-based therapies fail our patients,” said Dr. Wrangle. “The QUILT-3.055 study enrolled patients relapsed after CPI and CPI in combination with chemotherapy and showed that, regardless of prior therapy, adding the IL-15-based superagonist ANKTIVA to their therapy could rescue checkpoint activity likely through activation of NK cells, CD4+, CD8+, and memory T cells. The survival rate in these patients on their 2 nd or 3 rd line of cancer therapy is impressive and exceeds what you might expect from the current standard of care.” About the QUILT-3.055 Study Non-small cell lung cancer occurs when malignant cells form in the lung’s tissue and it accounts for approximately 85% of all lung cancer cases. Lung cancer is by far the leading cause of cancer death in the U.S., accounting for about 1 in 5 of all cancer deaths, according to the American Cancer Society. The QUILT-3.055 study examined overall survival in 86 patients with 2 nd and 3 rd line+ NSCLC who were previously treated and failed either CPI alone or failed CPI in combination with chemotherapy. These patients had received no intervening therapy. Patients received ANKTIVA 15 mcg/kg subcutaneously every 3 weeks in combination with the same checkpoint inhibitor they previously received and on which they had progressed. The median OS (n=86) was 14.1 months (95% CI 11.7, 17.4) with survival ranging up to 58 months. Overall survival for PDL1+ve (>1%) (N=53) was 13.8 months (95% CI 10.2, 16.2) versus PDL1-ve (N=33) of 15.8 months (95% CI 11.5, 24.0). The ANKTIVA adverse event profile was consistent with CPI alone with no cytokine release syndrome observed. Only 10% of participants had any grade ≥3 ANKTIVA-related adverse events. The study demonstrates long-term survival at ≥12 and ≥18 months of 49/86 (57%) and 29/86 (34%) patients respectively. ANKTIVA plus CPI therapy in 2 nd line or greater NSCLC demonstrated long-term median OS, independent of PDL1 status, and independent of prior lines of therapy in patients with acquired resistance to CPI. These findings support the novel mechanism of action of ANKTIVA to rescue CPI activity through the activation of NK and T cells, driving long-term memory, with median overall survival of 57% and 34% at 12 and 18 months, respectively, exceeding the standard of care. Based on the results of the QUILT 3.055 study and other trials involving ANKTIVA with checkpoint inhibitors, ImmunityBio is opening Phase 3 trials of ANKTIVA plus KEYTRUDA or OPDIVO in 1 st and 2 nd line NSCLC. “The clinical trial protocol was designed such that the duration of experimental therapy with ANKTIVA plus CPI was 24 months, and thereafter no further ANKTIVA doses were administered. Despite this, the results demonstrated that 27% of the participants survived beyond the 2-year therapy period, indicating the potential benefit of ANKTIVA to activate memory T cells and prolonged therapeutic benefit after study treatment was completed,” said Patrick Soon-Shiong, M.D., Executive Chairman, Founder and Global Chief Scientific and Medical Officer at ImmunityBio. “Based on this study, the ResQ studies have been activated as randomized Phase 3 trials in both 1 st. and 2 nd line NSCLC by combining ANKTIVA with pembrolizumab or nivolumab versus standard of care. The current results presented at World Congress on Lung Cancer confirm that by activating the body’s natural immune system and proliferating natural killer cells, killer T cells, and memory T cells, this IL-15 superagonist boosts, or rescues, the checkpoint inhibitor likely by reactivating MHC1 expression on the tumor. We are excited at the potential of converting a MHC-ve cold tumor to a MHC+ve hot tumor and evolving the field of immunotherapy beyond T cells.” About ANKTIVA ® The cytokine interleukin-15 (IL-15) plays a crucial role in the immune system by affecting the development, maintenance, and function of key immune cells—NK and CD8+ killer T cells—that are involved in killing cancer cells. By activating NK cells, ANKTIVA overcomes the tumor escape phase of clones resistant to T cells and restores memory T cell activity with resultant prolonged duration of complete response. ANKTIVA is a first-in-class IL-15 agonist IgG1 fusion complex, consisting of an IL-15 mutant (IL-15N72D) fused with an IL-15 receptor alpha, which binds with high affinity to IL-15 receptors on NK, CD4+, and CD8+ T cells. This fusion complex of ANKTIVA mimics the natural biological properties of the membrane-bound IL-15 receptor alpha, delivering IL-15 by dendritic cells and drives the activation and proliferation of NK cells with the generation of memory killer T cells that have retained immune memory against these tumor clones. The proliferation of the trifecta of these immune killing cells and the activation of trained immune memory results in immunogenic cell death, inducing a state of equilibrium with durable complete responses. ANKTIVA has improved pharmacokinetic properties, longer persistence in lymphoid tissues, and enhanced anti-tumor activity compared to native, non-complexed IL-15 in-vivo. ANKTIVA was recently approved by the FDA for BCG-unresponsive non-muscle invasive bladder cancer CIS with or without papillary tumors. For more information, visit Anktiva.com. Indication and Important Safety Information INDICATION AND USAGE ANKTIVA is an interleukin-15 (IL-15) receptor agonist indicated with Bacillus Calmette-Guerin (BCG) for the treatment of adult patients with BCG-unresponsive nonmuscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors. WARNINGS AND PRECAUTIONS Risk of Metastatic Bladder Cancer with Delayed Cystectomy. Delaying cystectomy can lead to the development of muscle invasive or metastatic bladder cancer, which can be lethal. If patient with CIS do not have a complete response to treatment after a second induction course of ANKTIVA with BCG, reconsider cystectomy. DOSAGE AND ADMINISTRATION For lntravesical Use Only.
