Kamada Announces Launch of a Comprehensive Post-Marketing

Research Program for CYTOGAM

REHOVOT, Israel, and HOBOKEN, NJ - May

5, 2025 -- Kamada Ltd. (NASDAQ: KMDA; TASE: KMDA.TA), a global biopharmaceutical company with a portfolio of marketed products indicated

for rare and serious conditions and a leader in the specialty plasma-derived field, today announced the launch of a new post-marketing

research program aimed at generating key data in support of the benefits of CYTOGAM , the Company's Cytomegalovirus Immune Globulin,

in the management of cytomegalovirus (CMV) in solid organ transplantation.

The research program, developed in collaboration

with leading Key Opinion Leaders (KOLs), is directed at advancing CMV disease management through novel strategies focused on late-onset

CMV prevention and mitigation of active CMV disease, exploring alternative dosing strategies, and investigating potential new applications

of CYTOGAM. The program also includes research aimed at enhancing the understanding of CYTOGAM's mechanism of action and its functional

properties against CMV and other viruses. Health economic studies to analyze the cost burden of CMV in solid organ transplantation are

also planned, along with a clinical practice study to better understand the nuances of current CMV management in lung transplantation.

"CMV disease continues to be a significant

risk factor for graft rejection and mortality in organ transplantation, however, for years no material new up-to-date clinical data regarding

the benefits of CYTOGAM were published," said Amir London, Kamada's Chief Executive Officer. "We believe that the data

to be generated through our comprehensive program may demonstrate the various benefits of CYTOGAM in the prevention and management of

CMV disease, supporting further product utilization over the coming years. This innovative program highlights our commitment to addressing

CMV infection in solid organ transplanted patients through cutting-edge research and collaborations with leading experts in the field.

We appreciate the participating thought leaders and their collaboration and support around the design and prioritization of the studies."

The U.S. Food and Drug Administration (FDA) approved

Kamada's application to manufacture CYTOGAM in May 2023. During the year ended December 31, 2024, Kamada recognized revenues of

$22.5 million from sales of CYTOGAM, a 31% increase over the prior fiscal year.

Over the past two years, Kamada has engaged KOLs

to study and present their ongoing clinical experiences with CYTOGAM. At ID Week 2023, Fernando Torres M.D., Clinical Chief, Division

of Pulmonary and Critical Care at University of Texas Southwestern Medical Center, presented the results of his investigator-initiated

five-year retrospective cohort study of 325 lung-transplant patients comparing CYTOGAM in combination with anti-viral agents for CMV prophylaxis

in high-risk CMV-mismatch to intermediate and low CMV risk lung transplant patients. In their presentation, Dr. Torres and his colleagues

concluded that the use of a proactive multimodality CMV prophylaxis, consisting of antivirals and immune augmentation with CMV immunoglobulin,

may improve outcomes among high-risk CMV mismatch lung transplant recipients. At the American Transplant Congress in 2024, Jennifer Chow,

MD, Transplant Infectious Diseases specialist at Tufts Medical Center, presented the results of an IIS analyzing the stored samples of

a previously conducted placebo-controlled randomized controlled interventional study of CYTOGAM prophylaxis that demonstrates the potential

anti-viral and disease attenuation effect of CYTOGAM in moderate to low CMV risk liver transplant patients. Recently, in April 2025, Kamada

presented the results of internal research comparing the functional properties of CYTOGAM and regular immune globulin intravenous (IVIG)against

CMV and other common viruses at the International Society for Heart & Lung Transplantation 2025 Annual Meeting. The study demonstrates

that CYTOGAM has 4-fold higher anti-CMV antibodies than regular IVIGs, while also highlighting the polyvalent characteristics of both

hyperimmune globulins, such as CYTOGAM, and regular IVIGs, which are not well described in the literature.

CYTOGAM (Cytomegalovirus Immune Globulin

Intravenous [Human]) (CMV-IGIV) is indicated for the prophylaxis of cytomegalovirus disease associated with the transplantation of the

kidney, lung, liver, pancreas and heart. The product is the sole FDA-approved immunoglobulin (IgG) product for this indication.

Important Safety Information

CYTOGAM is contraindicated in individuals with

a history of a prior severe reaction associated with the administration of this or other human immunoglobulin preparations. Persons with

selective immunoglobulin A deficiency have the potential for developing antibodies to immunoglobulin A and could have anaphylactic

reactions to subsequent administration of blood products that contain immunoglobulin A, including CYTOGAM.

Immune Globulin Intravenous (Human) products have

been reported to be associated with renal dysfunction, acute renal failure, osmotic nephrosis and death. Patients predisposed to acute

renal failure include patients with any degree of preexisting renal insufficiency, diabetes mellitus, age greater than 65, volume

depletion, sepsis, paraproteinemia, or patients receiving known nephrotoxic drugs. Especially in such patients, IGIV products should be

administered at the minimum concentrations available and the minimum rate of infusion practicable. Agents containing sucrose as a stabilizer

(CYTOGAM contains sucrose) have been associated with reports of renal dysfunction given at daily doses of 350 mg/kg or greater.

During administration, the patient's vital

signs should be monitored continuously, and careful observation made for any symptoms throughout the infusion. Epinephrine and diphenhydramine

should be available for the treatment of an acute anaphylactic reaction.

Increases in serum creatinine and blood urea nitrogen

(BUN) have been observed as soon as one to two days following IGIV infusion. Progression to oliguria or anuria requiring dialysis has

Immune Globulin Intravenous (Human) products can

contain blood group antibodies which may act as hemolysins and induce in vivo coating of red blood cells with immunoglobulin, causing

a positive direct antiglobulin reaction and, rarely, hemolysis.

CYTOGAM is derived from human plasma. As with

all plasma-derived products, the risk of transmission of infectious agents, including viruses and, theoretically, the Creutzfeldt-Jakob

disease (CJD) agent, cannot be completely eliminated.

Minor reactions, such as flushing, chills,

muscle cramps, back pain, fever, nausea, vomiting, arthralgia, and wheezing, were the most frequent adverse reactions observed during

the clinical trials for CYTOGAM.
