Dr. Reddy’s Laboratories received a massive bump to their market cap on the 5th of June, 2025, when they announced a new collaboration with Alvotech from Iceland to co-develop a biosimilar for pembrolizumab. Pembrolizumab alone is worth 29.5 billion dollars in worldwide sales as of the year 2024. Now, the collaboration increased Dr. Reddy’s share price by 4.1%, which is a notable milestone for the Indian company and a step up from their previous valuation. The article focuses on how this partnership is likely to affect their stock performance and what its broader ramifications might be for the global biosimilars landscape.

Strategic Collaboration with Alvotech: A Game-Changing Partnership
The focal point of the collaboration between Dr. Reddy and Alvotech is a biosimilar for Keytruda, one of the most highly regarded immuno-oncology medicines for treating lung, melanoma, and head and neck cancers. The two companies will share developmental and manufacturing responsibilities alongside utilizing their existing capabilities in biosimilars to expedite the work. The partnership offers global commercialization rights to all parties, sans a few exceptions, enabling the capture of a segment of Keytruda’s enormous market.
Synergy in Expertise
Having over 25 years of experience in biologics and six commercialized biosimilars under their belt, Dr. Reddy’s positions itself at the forefront of manufacturing and marketing. Alvotech’s renowned biosimilar R&D platform further strengthens the partnership with its innovation capabilities. With the expectation that this synergy will accelerate the timeline to market and increase global reach for the biosimilar, it stands to serve as an economical substitute for Keytruda.
Stock Surge and Investor Confidence
The announcement resulted in a 4% surge in Dr. Reddy’s stock, becoming a top gainer on the Nifty 50 index on June 5, 2025. The stock reached a four-month high of ₹1,301.70, demonstrating strong investor optimism about the partnership’s potential to elevate revenue. In the last month, Dr. Reddy’s shares have seen a 9% increase, significantly outperforming the Nifty 50’s 1% rise, showcasing the market’s confidence in the company’s strategic decisions.
Oncology as a Growth Driver
Diabetes happens to be one of the major chronic conditions in the country, developing at an unsettling rate. Dr. Reddy’s CEO Erez Israeli shared the need to address this therapeutic focus area with oncology, stating that the collaboration bolsters the firm’s strength in immuno-oncology, underscoring that it is a central therapy. The biosimilar would allow Dr. Reddy’s to tap into the rapidly expanding segment, further strengthening its global oncology portfolio.
Broader Implications for Biosimilars: Addressing Global Healthcare Needs
Restrained by finances, many patients around the world find it difficult to access vital treatments. Biosimilars not only solve this problem but also provide affordable treatment alternatives as they are closely related to existing biologic drugs. The Keytruda bisimilar aids cancer patients as cancer treatments tend to be unbelievably expensive. The goal of the partnership, which includes Dr. Reddy’s and Alvotech, is to create a low-priced alternative using the rough market scope of Dr. Reddy’s in the US and Alvotech’s R&D skills.
Competitive Landscape
The global market of oncology biosimilars is set to boom as more and more branded medications, like Keytruda, lose their patents. Thanks to this aid, Dr. Reddy’s and Alvotech will be placed in a great position against several other competing companies in the oncology biosimilar market. The oncology biosimilars market is competitive and targets many pharmaceutical companies, raising the chances of success for this venture but shortening the chances for future purchases in this sector if not managed smartly.

Challenges and Opportunities: Regulatory and Development Hurdles
When it comes to developing biosimilar drugs, especially in the US, dealing with the FDA’s rigid standards makes the process tedious and convoluted. The good news is that Alvotech recently passed the FDA’s requirement gauntlet with a different Dr. Reddy’s biosimilar application (AVT03). As optimistic as this news sounds, guaranteed swift approval along with other factors like scalability will be the components that will need to be solved immediately in order for the venture to succeed.
Market Dynamics and U.S. Policy Risks
Even as the partnership bolsters Dr. Reddy’s oncology portfolio, realignments of U.S. policy like proposed cuts to drug pricing by President Trump in May 2025 are likely to affect profit margins for Indian pharma players dependent on U.S. generics and biosimilars. However, the April 2025 tariff relief on pharmaceuticals is beneficial to the U.S. operations of Dr. Reddy’s.
Looking Ahead
The new partnership with Alvotech positions Dr. Reddy‘s strategically to target a share of the $29.5 billion Keytruda market. The companies intend to utilize their integrated abilities to create a low-cost biosimilar, which will improve patient access while increasing revenue. As Dr. Reddy’s stock continues to shine, this partnership highlights the changing narrative of India in the global biosimilars market.
