Dr. Reddy's and Pharmazz, Inc. enter into licensing agreement to

market first-in-class Centhaquine (Lyfaquin®) for hypovolemic shock

in India

• Centhaquine is a first-of-its-kind resuscitative agent to treat hypovolemic shock by increasing stroke volume and cardiac output due to an increase in (preload) venous blood return to the heart and a decrease in (afterload) due to arterial dilatation
• India is the first global territory in which Centhaquine (Lyfaquin®) is being launched immediately
• The partnership marks Dr. Reddy's latest strategic collaboration to bring innovative products and novel molecules to India

Hyderabad, India; March 22, 2024 - Dr. Reddy's Laboratories Ltd. (BSE: 500124, NSE: DRREDDY,

NYSE: RDY, NSEIFSC: DRREDDY; hereafter referred to as "Dr. Reddy's"), a global pharmaceutical company, has entered into a license agreement with Pharmazz, Inc. ("Pharmazz"), a U.S. based biopharmaceutical company developing and commercialising drug products to treat critically ill patients, to commercialise the first-in-class innovative drug Centhaquine in India. Developed by Pharmazz, Centhaquine is a resuscitative agent presently indicated for the treatment of hypovolemic shock by the Drugs Controller General of India (DCGI).

As per the agreement, Dr. Reddy's has received exclusive rights to market and distribute Centhaquine in India. Pharmazz will be entitled to upfront payments and royalties. Dr. Reddy's will market the product under the brand name Lyfaquin®, which it shall own. In addition to India, Dr. Reddy's also receives marketing rights for Lyfaquin® from Pharmazz for Nepal.

M.V. Ramana, Chief Executive Officer, Branded Markets (India and Emerging Markets), Dr.

Reddy's, said: "The partnership with Pharmazz and launch of this first-in-class drug marks the latest in our effort to enter into strategic collaborations to bring novel molecules to India to meet genuine unmet patient needs. The clinical studies for Lyfaquin® have demonstrated significantly better and promising outcomes, making it as a potential add-on drug in the management of hypovolemic shock and enhancing the current standard of care for its treatment in India."

Dr. Prof. Anil Gulati, M.D., Ph.D., inventor, CEO, and Chairman of the Board of Directors of

Pharmazz, said: "India's emergence as a hub for developing and introducing innovative medicines is a remarkable achievement. It reflects the country's growing capabilities in research and development within the pharmaceutical sector. It is a large step for Pharmazz to partner with Dr. Reddy's, a leading global pharmaceutical company from India. For patients with hypovolemic shock, I believe Dr. Reddy's is the best partner for Pharmazz to market Centhaquine, an innovative, first-in-class novel resuscitative agent, in India."

Hypovolemic shock is a life-threatening and often a fatal condition1. Severe loss of blood or fluids due to traumatic haemorrhage, postpartum haemorrhage, gastrointestinal bleeding, post-surgical bleeding, diarrhoea or vomiting can cause hypovolemic shock, which may lead to multi-organ failure and death. India has a high prevalence of these conditions and high mortality due to these conditions2. Data from various Indian studies and registries suggests a mortality rate of around 10 to 15% in traumatic haemorrhages despite the existing standard of care3. This suggests a need for a novel resuscitative agent which can improve the existing standard of care.

About Centhaquine (Lyfaquin® in India): Centhaquine is a frontline therapy used along with the standard of care and is well- positioned to a critical unmet need as a pharmacologically active resuscitative agent. A decrease in the volume of blood circulation from blood or fluid loss due to trauma, gastrointestinal bleeding, major surgery, postpartum hemorrhage, diarrhea, or vomiting can cause hypovolemic shock. About 1.9 million people worldwide die because of hemorrhagic shock every year, most dying within the first 6 hours. Centhaquine activates venous alpha2B adrenergic receptors to increase cardiac preload and activates central alpha2A adrenergic receptors to decrease cardiac afterload. Thereby, Centhaquine converts the venous unstressed blood volume to stressed blood volume and improves cardiac output and blood circulation, making it an ideal candidate for the resuscitation of patients with hypovolemic shock.

Centhaquine was approved in India by Drugs Controller General of India following a successful phase III clinical trial. The results of are published in a manuscript entitled "A Multicentric, Randomized, Controlled Ph III Study of Centhaquine (Lyfaquin®), as a Resuscitative Agent in Hypovolemic Shock Patients". The manuscript is published in DRUGS and is available at: https://link.springer.com/article/10.1007/s40265-021-01547-5

Pharmazz received permission from the U.S. Food and Drug Administration (FDA) to conduct a Phase III clinical trial of centhaquine in hypovolemic shock patients. It assesses the safety and efficacy of centhaquine in patients with hypovolemic shock. The Phase

1. randomized double-blind,placebo-controlled study will be conducted in 430 patients where patients will receive either an intravenous infusion of 0.01 mg/Kg of centhaquine or a placebo. All patients will receive the standard of care. A 28-dayall-cause mortality is the primary endpoint.

Currently, Centhaquine is also under development for septic shock.
