Dr. Reddy’s Laboratories Ltd. (RDY) and Immutep Limited have entered into a strategic collaboration and exclusive licensing agreement that will allow RDY to develop and commercialize the LAG‑3 agonist Eftilagimod Alfa (efti) in all countries outside North America, Europe, Japan, and Greater China. The agreement provides RDY with an upfront payment of US$20 million and the possibility of milestone payments totaling up to US$349.5 million, along with double‑digit royalties on sales in the licensed territories.
The partnership expands RDY’s oncology footprint by adding a first‑in‑class immunotherapy to its pipeline. RDY will leverage its established commercial network in the licensed markets to accelerate market entry, while Immutep retains control of the most lucrative pharmaceutical regions and global manufacturing rights. The limited geographic scope explains why the deal is viewed as a strategic, but not transformative, expansion for RDY, and why investors have reacted with caution.
Eftilagimod Alfa is currently in pivotal Phase III trials for non‑small‑cell lung cancer (NSCLC) and is also being studied in head‑and‑neck cancer, breast cancer, and soft‑tissue sarcoma. The drug’s mechanism—activating the immune system by targeting the LAG‑3 checkpoint—positions it as a potential partner for existing checkpoint inhibitors such as pembrolizumab (Keytruda) and for combination chemotherapy regimens. If the Phase III data are positive, efti could become a significant new revenue driver for both companies.
Market reaction to the announcement has been muted. Shares of RDY closed slightly lower on the day of the announcement, a pattern that analysts attribute to the deal’s exclusion of North America, Europe, Japan, and Greater China, the regions that generate the bulk of global oncology sales. The fact that Immutep retains manufacturing rights and that efti is still in Phase III trials also dampens enthusiasm, as the immediate commercial upside is limited and the outcome of the trials remains uncertain.
M.V. Ramana, CEO of Dr. Reddy’s Branded Markets, said the collaboration “continues our commitment to delivering first‑in‑class therapies for cancer treatment” and highlighted the potential of efti to set a new standard of care when combined with pembrolizumab and chemotherapy in NSCLC. Marc Voigt, CEO of Immutep, noted that the partnership “captures significant value for efti in the licensed markets while preserving full rights in key markets” and praised RDY’s global reach as an ideal platform to maximize patient access.
The deal provides Immutep with critical funding and a commercial partner for its late‑stage candidate, while giving RDY a foothold in the growing LAG‑3 immunotherapy space. For investors, the collaboration signals RDY’s continued shift toward high‑margin oncology products, but the limited scope and Phase III status suggest that the partnership will be a long‑term growth driver rather than an immediate revenue boost.
