Insights

Strategic Saudi partnership sets a clear potential path to Multikine commercialization.

CEL-SCI has secured Amarox as its regulatory and commercial partner for Multikine in Saudi Arabia. Amarox will manage all SFDA interactions, seek Breakthrough Medicine Designation, and, upon approval, hold exclusive distribution rights, while revenues are split on a 50%/50% net basis.

The agreement keeps Multikine ownership, manufacturing know-how, and global rights with CEL-SCI, limiting structural concessions to shared local economics. It leverages Amarox’s established SFDA track record and oncology focus in a region where immunotherapy is projected to become a $2.7 billion cancer market by 2033.

Actual financial impact depends on achieving SFDA Breakthrough Medicine Designation and subsequent approval, as Multikine remains investigational. Further clarity on regulatory progress, timing, and any GCC expansion terms would likely come from subsequent company communications and future filings.

Saudi immunotherapy market $2.7 billion by 2033 Projected size of Saudi cancer immunotherapy segment
Revenue split 50%/50% net revenue Multikine sales in Saudi Arabia between CEL-SCI and Amarox
Head and neck cancer incidence 900,000 cases per year Newly diagnosed head and neck cancer cases globally
Patients dosed with Multikine Over 740 patients Cumulative Multikine dosing experience referenced
SFDA shortage ranking period 3 consecutive years Amarox ranked #1 in 2022, 2023, 2024
Breakthrough Medicine Designation regulatory
"including seeking the SFDA’s Breakthrough Medicine Designation which, upon granting, would make Multikine rapidly available"
A breakthrough medicine designation is a formal status granted by a drug regulator that signals a new treatment shows substantial promise for a serious condition and qualifies for faster, more intensive review. For investors it matters because the designation can shorten development time, reduce some regulatory hurdles and raise the likelihood of eventual approval, similar to giving a promising product a VIP fast‑track through the approval process which can boost a company’s value and investor interest.
neoadjuvant immunotherapy medical
"potentially making Saudi Arabia the first region in the world to commercialize this neoadjuvant immunotherapy"
Orphan Drug designation regulatory
"received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma"
Orphan drug designation is a special status given to medicines developed to treat rare diseases affecting only a small number of people. This status often provides benefits like faster approval processes and financial incentives, making it more attractive for companies to develop these drugs. For investors, it signals potential for exclusive market rights and reduced competition, which can impact the drug’s profitability.
Saudi Food and Drug Authority (SFDA) regulatory
"lead all communications with the Saudi Food and Drug Authority (SFDA)"
Saudi Food and Drug Authority (SFDA) is the national regulator that sets and enforces safety and quality rules for food, medicines, medical devices and cosmetics in Saudi Arabia. Its approvals, inspections and rules act like traffic signals for companies — green lights let products be sold and grow revenue, while delays or restrictions can limit market access, affect sales and change a company’s investment risk and value.
Vision 2030 other
"in alignment with Saudi Arabia’s Vision 2030 initiative"
A "Vision 2030" is a publicly stated long-range roadmap that sets goals, reforms and priorities a government or company intends to achieve by the year 2030. For investors it signals the areas likely to receive funding, regulatory change or policy support—like new industries, infrastructure or cost cuts—so it helps spot potential opportunities and risks much like a route map shows which roads will be expanded or closed over the next decade.

Dr. Abdullah Alzomaie, Chief Executive Officer of Amarox noted: “Saudi Arabia is rapidly advancing its position as a regional hub for innovative healthcare and advanced therapies. We are pleased to collaborate with CEL-SCI in exploring the regulatory pathway for Multikine and evaluating its potential role in addressing unmet needs in oncology care across Saudi Arabia and the GCC region.”

About Multikine

 

Multikine is a cancer immunotherapy administered before surgery as a treatment for newly diagnosed previously untreated head and neck cancer. Its goal is to activate a person’s immune system to fight cancer before the ravages of surgery, radiation and chemotherapy have weakened the immune system.

About Head and Neck Cancer

 

Head and neck cancer is the 6th most common cancer, with approximately 900,000 newly diagnosed cases per year globally. The newly diagnosed stage 3 and 4 patients with this cancer represent a severe unmet need.

 

About CEL-SCI Corporation

 

CEL-SCI believes that boosting a patient’s immune system before surgery, radiotherapy and chemotherapy have damaged it, should provide the greatest possible impact on survival. Multikine is designed to help the immune system "target" 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.

 

Multikine (Leukocyte Interleukin, Injection), given right after diagnosis and before surgery, has been dosed in over 740 patients and received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck.

The Company has operations in Vienna, Virginia, and near/in Baltimore, Maryland.
