The Leukocyte Interleukin Injection (LI) [aka Multikine*] talk, was delivered by Philip Lavin, PhD, lead biostatistician for over 80 regulatory approvals\/clearances who has also served on multiple U.S. Food and Drug Administration (FDA) review panels. Dr. Lavin is the lead biostatistician for CEL-SCI\u2019s IT-MATTERS study.<\/p>\n<p>\nTumor cell PD-L1, also known as PD-L1 (Programmed Death-Ligand 1), a protein that plays a crucial role in immune system regulation, is a target pathway for immune checkpoint inhibitors, a major class of oncology drugs. These work by blocking the interaction between tumor cell PD-L1 and the PD-1 receptor. The global PD-L1\/PD-1 therapeutics market was valued at $34.8 billion in 2022 and includes two drugs approved for head and neck cancer, specifically unresectable recurrent or metastatic SCCHN, Keytruda and Opdivo.<\/p>\n<p>\nWhile pembrolizumab (Keytruda) and nivolumab (Opdivo) are approved for use in recurrent and metastatic head and neck cancer, CEL-SCI\u2019s Phase 3 data showed that Multikine prolonged overall survival in the lower risk for recurrence advanced primary head and neck cancer patients and more so in a subset comprising &gt;70% of the lower-risk patients (all had low levels (defined as TPS&lt;10) of tumor cell PD-L1 expression).<\/p>\n<p>\n\u201cThis data is of great interest in that, in our opinion, they suggest Multikine can be effective in extending life in patients who are generally not well served by checkpoint inhibitors. A combination of Multikine and drugs like Keytruda or Opdivo may in fact extend the reach of coverage in this hard-to-treat disease and thus help more patients, indicating a promising new treatment path,\u201d stated CEL-SCI CEO Geert Kersten. \u201cOur immediate opportunity is in head and neck cancer, yet these latest results also point to potential in other solid tumors as well. We are interested in running such combination studies.\u201d<\/p>\n<p>\nThe AHNS presentation focused on biomarker analysis, specifically featuring tumor cell PD-L1, from tumor specimens that were collected from nearly half of the patients in CEL-SCI\u2019s pivotal Phase 3 study.<\/p>\n<p>\nIn June of 2021, a Multikine study reported a statistically significant 14.1% absolute 5-year overall survival benefit in the intent to treat (ITT; n=923) subjects who were categorized as lower risk for recurrence (LR; n=380) per National Comprehensive Cancer Network (NCCN) guidelines and received Multikine followed by surgery and radiotherapy, as compared to control LR subjects who received only standard of care (SOC) (surgery plus radiotherapy), resulting in a near 4-year median overall survival advantage over control (101.7 <i>vs<\/i> 55.2 months). The Company is pursuing paths to marketing approval for Multikine in the treatment of head and neck cancer in the USA, Canada, the UK and the European Union.<\/p>\n<p>\nHighlights of the data we presented at AHNS conference include:<\/p>\n<ul class=\"bwlistdisc\">\n<li>\nA Kaplan-Meier lifetable for low tumor cell PD-L1 (defined as TPS &lt;10) demonstrated a significant log rank test (2-sided p=0.034) favoring the Multikine plus Standard of care (SOC) group <i>vs<\/i> SOC alone; there was an absolute 20% survival advantage at 5-year favoring both Multikine plus SOC (~60% alive) vs SOC alone (~40% alive)<\/p>\n<\/li>\n<li>\nThe PD-L1 low subgroup represents &gt;70% of all LR subjects<\/p>\n<\/li>\n<li>\nTwo-way and three-way interaction models for the LR population confirmed statistical significance favoring Multikine treatment regimen plus SOC <i>vs<\/i> SOC alone with a 0.6 hazard ratio for 3-way interaction and a 0.55 hazard ratio for the 2-way interaction <i>vs<\/i> 0.68 hazard ratio for the study LR population that contained all patients, not just those with low PD-L1 (TPS &lt;10)<\/p>\n<\/li>\n<li>\nThe data suggest potential benefits for combining Multikine with checkpoint inhibitors to further improve overall survival outcome in this hard-to-treat patient population.<\/p>\n<\/li>\n<\/ul>\n<p><b>About CEL-SCI Corporation<\/b><\/p>\n<p>\nCEL-SCI believes that boosting a patient\u2019s immune system while it is still intact should provide the greatest possible impact on survival. Therefore, in the Phase 3 study, CEL-SCI studied patients who were newly diagnosed with locally advanced primary squamous cell carcinoma of the head and neck with the investigational product Multikine first, BEFORE they received surgery and radiotherapy or surgery plus concurrent radiotherapy and chemotherapy (the current standard of care for these patients). We believe, this approach is unique. Most other cancer immunotherapies are administered only after conventional therapies have been tried and\/or failed. Multikine (Leukocyte Interleukin, Injection) received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck.<\/p>\n<p>\nMultikine is designed to help the immune system \u201ctarget\u201d the tumor at a time when the immune system is still relatively intact and thereby thought to be better able to mount an attack on the tumor.<\/p>\n<p>\nThe Company has operations in Vienna, Virginia, and near\/in Baltimore, Maryland.<\/p>\n<p><b>Forward-Looking Statements<\/b><\/p>\n<p>\nThis press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.
