ABOUT BRIUMVI (ublituximab-xiiy) 150 mg/6 mL Injection for IV
BRIUMVI is a novel monoclonal antibody that targets a unique epitope on CD20-expressing B-cells. Targeting CD20 using monoclonal antibodies has proven to be an important therapeutic approach for the management of autoimmune disorders, such as RMS. BRIUMVI is uniquely designed to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, allows for efficient B-cell depletion at low doses.

BRIUMVI is indicated in the U.S. for the treatment of adults with RMS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease and in the EU and UK for the treatment of adult patients with RMS with active disease defined by clinical or imaging features.

A list of authorized specialty distributors can be found at www.briumvi.com.

IMPORTANT SAFETY INFORMATION

Contraindications: BRIUMVI is contraindicated in patients with:

Active Hepatitis B Virus infection

A history of life-threatening infusion reaction to BRIUMVI

WARNINGS AND PRECAUTIONS

Infusion Reactions: BRIUMVI can cause infusion reactions, which can include pyrexia, chills, headache, influenza-like illness, tachycardia, nausea, throat irritation, erythema, and an anaphylactic reaction. In MS clinical trials, the incidence of infusion reactions in BRIUMVI-treated patients who received infusion reaction-limiting premedication prior to each infusion was 48%, with the highest incidence within 24 hours of the first infusion. 0.6% of BRIUMVI-treated patients experienced infusion reactions that were serious, some requiring hospitalization.

Observe treated patients for infusion reactions during the infusion and for at least one hour after the completion of the first two infusions unless infusion reaction and/or hypersensitivity has been observed in association with the current or any prior infusion. Inform patients that infusion reactions can occur up to 24 hours after the infusion. Administer the recommended pre-medication to reduce the frequency and severity of infusion reactions. If life-threatening, stop the infusion immediately, permanently discontinue BRIUMVI, and administer appropriate supportive treatment. Less severe infusion reactions may involve temporarily stopping the infusion, reducing the infusion rate, and/or administering symptomatic treatment.

Infections: Serious, life-threatening or fatal, bacterial and viral infections have been reported in BRIUMVI-treated patients. In MS clinical trials, the overall rate of infections in BRIUMVI-treated patients was 56% compared to 54% in teriflunomide-treated patients. The rate of serious infections was 5% compared to 3% respectively. There were 3 infection-related deaths in BRIUMVI-treated patients. The most common infections in BRIUMVI-treated patients included upper respiratory tract infection (45%) and urinary tract infection (10%). Delay BRIUMVI administration in patients with an active infection until the infection is resolved.

Consider the potential for increased immunosuppressive effects when initiating BRIUMVI after immunosuppressive therapy or initiating an immunosuppressive therapy after BRIUMVI.

Hepatitis B Virus (HBV) Reactivation: HBV reactivation occurred in an MS patient treated with BRIUMVI in clinical trials. Fulminant hepatitis, hepatic failure, and death caused by HBV reactivation have occurred in patients treated with anti-CD20 antibodies. Perform HBV screening in all patients before initiation of treatment with BRIUMVI. Do not start treatment with BRIUMVI in patients with active HBV confirmed by positive results for HB surface antigen (HBsAg) and anti-HB tests. For patients who are negative for HBsAg and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult a liver disease expert before starting and during treatment.

Progressive Multifocal Leukoencephalopathy (PML): Although no cases of PML have occurred in BRIUMVI-treated MS patients, JC virus infection resulting in PML has been observed in patients treated with other anti-CD20 antibodies and other MS therapies.

If PML is suspected, withhold BRIUMVI and perform an appropriate diagnostic evaluation. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.

MRI findings may be apparent before clinical signs or symptoms; monitoring for signs consistent with PML may be useful. Further investigate suspicious findings to allow for an early diagnosis of PML, if present. Following discontinuation of another MS medication associated with PML, lower PML-related mortality and morbidity have been reported in patients who were initially asymptomatic at diagnosis compared to patients who had characteristic clinical signs and symptoms at diagnosis.

If PML is confirmed, treatment with BRIUMVI should be discontinued.

Vaccinations: Administer all immunizations according to immunization guidelines: for live or live-attenuated vaccines, at least 4 weeks and, whenever possible, at least 2 weeks prior to initiation of BRIUMVI for non-live vaccines. BRIUMVI may interfere with the effectiveness of non-live vaccines. The safety of immunization with live or live-attenuated vaccines during or following administration of BRIUMVI has not been studied. Vaccination with live virus vaccines is not recommended during treatment and until B-cell repletion.

Vaccination of Infants Born to Mothers Treated with BRIUMVI During Pregnancy: In infants of mothers exposed to BRIUMVI during pregnancy, assess B-cell counts prior to administration of live or live-attenuated vaccines as measured by CD19+ B-cells. Depletion of B-cells in these infants may increase the risks from live or live-attenuated vaccines. Inactivated or non-live vaccines may be administered prior to B-cell recovery. Assessment of vaccine immune responses, including consultation with a qualified specialist, should be considered to determine whether a protective immune response was mounted.

Fetal Risk: Based on data from animal studies, BRIUMVI may cause fetal harm when administered to a pregnant woman. Transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other anti-CD20 B-cell depleting antibodies during pregnancy. A pregnancy test is recommended in females of reproductive potential prior to each infusion. Advise females of reproductive potential to use effective contraception during BRIUMVI treatment and for 6 months after the last dose.

Reduction in Immunoglobulins: As expected with any B-cell depleting therapy, decreased immunoglobulin levels were observed. Decrease in immunoglobulin M (IgM) was reported in 0.6% of BRIUMVI-treated patients compared to none of the patients treated with teriflunomide in RMS clinical trials. Monitor the levels of quantitative serum immunoglobulins during treatment, especially in patients with opportunistic or recurrent infections, and after discontinuation of therapy, until B-cell repletion. Consider discontinuing BRIUMVI therapy if a patient with low immunoglobulins develops a serious opportunistic infection or recurrent infections, or if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins.

Most Common Adverse Reactions: The most common adverse reactions in RMS trials (incidence of at least 10%) were infusion reactions and upper respiratory tract infections.

ABOUT MULTIPLE SCLEROSIS
Relapsing multiple sclerosis (RMS) is a chronic demyelinating disease of the central nervous system (CNS) and includes people with relapsing-remitting multiple sclerosis (RRMS) and people with secondary progressive multiple sclerosis (SPMS) who continue to experience relapses. RRMS is the most common form of multiple sclerosis (MS) and is characterized by episodes of new or worsening signs or symptoms (relapses) followed by periods of recovery. It is estimated that nearly 1 million people are living with MS in the United States and approximately 85% are initially diagnosed with RRMS.1,2 The majority of people who are diagnosed with RRMS will eventually transition to SPMS, in which they experience steadily worsening disability over time. Worldwide, more than 2.3 million people have a diagnosis of MS.

Immorta Bio is the first company to develop a "senolytic immunotherapy" for treatment of cancer and aging. This treatment comprises of training the immune system of patients to selectively kill "senescent cells" that promote aging and act as a shield to protect cancer against immune responses. By removing this defense mechanism, cancer becomes susceptible to immune attack.

The Company has shown that its lead senolytic immunotherapy product, SenoVax, is capable of destroying lung, breast, pancreatic and brain cancers, as well as melanoma3 in animal models.

"Having been chosen to present our work on using the immune system to fight cancer and aging in such an esteemed panel is truly an honor," said Dr. Thomas Ichim, President and Chief Scientific Officer of Immorta Bio.

T cell mediated mechanisms of how SenoVax enables its anticancer effects have previously been published in the peer-reviewed literature with collaborators at University of California San Diego, Georgetown University, Ceders Sainai, and Calidi Bio4. Additionally, the Company recently demonstrated that natural killer cell activation as a result of SenoVax therapy also plays a role in stimulation of cancer destruction5.

"We have founded Immorta Bio on the principle of ‘Scientific’ Longevity," said Dr. Boris Reznik, President and CEO of Immorta Bio. "There is no better validation of our science than to be chosen to give an oral presentation at such a prestigious and exclusive scientific gathering as AAI2025."

FINANCIAL UPDATES

Stock Repurchase Program and Cash Runway

Authorized a Stock Repurchase Program in March 2025 of $75.0 million of the Company’s outstanding common stock

Cash and investments of $383.0 million as of March 31, 2025, and reiterating cash runway through year-end 2027
First Quarter 2025 Financial Results

Cash, cash equivalents and investments totaled $383.0 million as of March 31, 2025, compared to $420.8 million as of December 31, 2024, for a decrease of $37.8 million due primarily to operating activities and $4.4 million in shares repurchased offset by $15.0 million received from Vanda Pharmaceuticals for the license of imsidolimab.

Collaboration revenue was $27.8 million for the three months ended March 31, 2025, compared to $7.2 million for the three months ended March 31, 2024. The increase is due to a $11.0 million increase in royalties recognized for sales of Jemperli and $9.6 million in revenue recognized for the Vanda license agreement.

Research and development expenses were $41.2 million for the three months ended March 31, 2025, compared to $37.0 million for the three months ended March 31, 2024. The increase was due primarily to development costs relating to the Phase 2 trials in RA and UC for rosnilimab, and the Phase 1 trials for ANB033 and ANB101, offset by a decrease in development costs for imsidolimab and ANB032. The R&D non-cash, stock-based compensation expense was $4.4 for the three months ended March 31, 2025 as compared to $3.5 million in the same period in 2024.

General and administrative expenses were $14.1 million for the three months ended March 31, 2025, compared to $12.3 million for the three months ended March 31, 2024. The increase was due primarily to transaction costs associated with the Vanda Pharmaceuticals license agreement. The G&A non-cash, stock-based compensation expense was $4.8 million for the three months ended March 31, 2025 as compared to $6.7 million in the same period in 2024.

Net loss was $39.3 million for the three months ended March 31, 2025, or a net loss per share of $1.28, compared to a net loss of $43.9 million for the three months ended March 31, 2024, or a net loss per share of $1.64.
