Slide 3: Why is CEL-SCI so Valuable for Cancer Patients and Investors?
Why is CEL-SCI so Valuable for Cancer Patients and Investors? We all know people who were treated for their cancer, but then the cancer came back. Most recurrences end in death. Therefore, we seek to make the first treatment more successful and stop cancer recurrences. We do this by activating the i

Slide 11: What is Multikine?
What is Multikine? Multikine is an investigational cancer immunotherapy with little to no toxicity that activates the immune system of cancer patients. It is given before surgery, radiotherapy and chemotherapy have compromised or destroyed the immune system. Normally cancer drugs are developed for r
Slide 12: How Does Multikine Work?
How Does Multikine Work? Multikine is a mixture of natural cytokines (regulators of our immune system). It helps the body’s immune cells recognize a tumor when the immune system is strongest, before surgery, radiotherapy and chemotherapy. Published studies of cancer patients have shown anti-tumor im

Target Population for Confirmatory Study The 212-patient confirmatory study will focus on these Kaplan-Meier Overall Survival for Multikine target population (n=114) in the Phase 3 study patients: → Newly diagnosed locally advanced primary (stage 3 and 4) head and 5-year survival 73% neck cancer pat
Slide 17: Why “N0” (No Cancer in the Lymph Nodes)?
Why “N0” (No Cancer in the Lymph Nodes)? These stage 3 and 4 very sick cancer patients are the ones who have the best survival with Multikine and also the best tumor responses and tumor elimination as shown in the prior study. Why? • “N0”, no cancer in the lymph nodes, means a more functional immune
Slide 18: Why Low PD-L1 Tumor Expression?
Why Low PD-L1 Tumor Expression? 70% of the patients treated in our Phase 3 study had low or zero levels of PD-L1 expressed by their tumors. These patients had both the best tumor responses and the best survival with Multikine. PD-L1 is a brake on the immune system. Multikine works better if there is
Slide 19: We Focus on Those Cancer Patients Checkpoint Inhibitors Cannot Help
We Focus on Those Cancer Patients Checkpoint Inhibitors Cannot Help We are not competing with checkpoint inhibitors Keytruda and Opdivo, the most successful cancer drugs in the world, selling over $40 billion per year. • They extend survival in patients who have high levels of PD-L1 since they inhib
Slide 20: Why Is The Chance of Success for the Study so High?
Why Is The Chance of Success for the Study so High? Very strong statistical significance shows likelihood of success in excess of 95%. CEL-SCI's subgroup is based on a large number of patients (n=114). “N0” (no cancer in the lymph nodes) selection was pre-specified in the protocol. The selection for

Slide 23: When Can the Study Lead to an Approval?
When Can the Study Lead to an Approval? Per the FDA, we will be allowed to see the tumor response data after full enrollment. At that time, we plan to discuss with the FDA and other countries’ regulators an early approval based on pre-surgical tumor responses shown to predict survival. The very end
