Oncology Drug Manufacturing in Asia: Key Manufacturers and Regulatory Insights

September 2, 2025

Oncology drug manufacturing has been extremely successful around the world and Asia is becoming a leader in the manufacture of cancer therapies. Asia has abundant contract manufacturers, as well as multinational pharma companies in India, China and South Korea, that are propelling the future of oncology drugs. In this post, we will identify the leaders in oncology drug manufacturing and the associated issues, and the changing regulatory environments in these dominant Asian countries. 


1. Introduction: Asia’s Rise in Oncology Drug Manufacturing

Asia is projected to greatly contribute to the future market, which is expected to surpass $200 billion by the year 2025.  Cancer biologics, targeted therapies, and immunotherapies are the specific oncology drugs that rejoice the battle of cancer. With the increasing volume of oncology drugs, issues of affordability, access, and innovation have put Asia, most notably India, China, and South Korea, in a strategically important position for global manufacturing.

With their size and quality of drug manufacturers, Asian countries, especially India, China and South Korea, are quickly positioning themselves as global manufacturing centers for lower-priced production in a highly regulated market. 


2. Major Oncology Drug Manufacturers in Asia


India: The Worldwide Pharmacy for Oncology Drugs

India is among the largest producers of generic drugs and has a growing oncology drug market. Indian contract manufacturers (CMOs) are vital to the global supply chain for oncology drugs, providing a wide variety of generic formulations, and more recently innovative treatments for cancer. Some prominent manufacturers include:

  • Dr. Reddy’s Laboratories - One of the leading companies in the global oncology industry, Dr. Reddy's Laboratories is well-known for producing generic oncology medications and has a robust pipeline of medications for targeted therapy and chemotherapy.

  • Cipla - Cipla is a significant player in the biosimilar oncology market and a leader in the production of generic oncology drugs.

  • Sun Pharmaceutical Industries - Sun Pharma has a deep oncology portfolio and is translating both generics and branded therapies for oncology indications.

  • Biocon - One of the leading providers of biologics, especially oncology-related biosimilars, Biocon has received recognition for its work on monoclonal antibodies and other targeted treatments.


China: Capacity and Innovation

The biopharmaceutical and oncological sectors have significantly increased the size of China's pharmaceutical industry. With the help of government assistance and cutting-edge facilities, Chinese biopharmaceutical companies are increasing their market shares abroad.

  • Hutchison China Meditech - Well-regarded for their work in oncology drug development and known for their clinical stage development of therapies for a range of cancers, including small molecules and biologics.
     
  • Zhejiang Hisun Pharmaceutical - Hisun has been involved in the producing generic oncology drugs and biosimilars, particularly for markets in the U.S. and Europe.
     
  • Shanghai Junshi Biosciences - Junshi Biosciences is a high-achieving biotech company developing monoclonal antibody-based therapeutics for oncology or immuno-oncology.
     

South Korea: Leader in Advanced Oncology Therapies

South Korea has become a leading innovator for advanced therapies including therapies for cancer such as cell and gene therapies. The country's biotech industry is very dynamic, and some key oncology drug manufacturers include:

  • Samsung Biologics - Samsung Biologics is a substantial contract manufacturer providing services to oncology drug developers worldwide, especially in the production of biologics and monoclonal antibodies. 
     
  • Celltrion - Celltrion continues to build an oncology portfolio focused on biosimilars and monoclonal antibodies and is a notable competitor in the global oncology biosimilars market. 
     
  • LG Chem - LG Chem has entered into oncology, developing both small molecules and biologic drugs, particularly immuno-oncology therapies.


3. Regulatory Insights: Understanding Oncology Drug Manufacturing in Asia

Manufacturing oncology drugs in overseas locations, more so in Asia, entails numerous challenges. One of them is dealing with the regulations. The regulation framework is different in every region, and each area has a set of rules, guidelines, and authorization steps to be followed in order to comply to both the local and international GMP standards.


India: The CDSCO and Global Compliance 

The Central Drugs Standard Control Organization (CDSCO) oversees drug approval and regulation in India. The CDSCO follows its own manufacturing guidelines that meet WHO-GMP requirements. Pharmaceutical manufacturers selling oncology drugs and products must first obtain CDSCO approval for their generics and biologics, to subsequently manufacture for the domestic market and globally. In particular, oncology product manufacturers should be aware of several key challenges and opportunities.

  • Challenges: Regulatory challenges including long approval times and stand-alone clinical testing requirements can delay the entry of oncology drugs into to the market.
  • Opportunities: India is a member of the World Trade Organization, agreeing to the TRIPS agreement which globally regulates protections for the generic oncology products.


China: Innovation and Change in Regulation 

In order to expedite the approval process for cancer medications from overseas producers, China has simultaneously modified the National Medical Products Administration (NMPA) rules. The NMPA works to speed up the clinical testing of new drugs or treatments and concentrates on innovative cancer treatments.

  • Challenges: Maintaining clinical trial standards for oncology drugs in the local area is still costly, time-consuming, and complex, despite improvements and the simplification of approvals brought about by the NMPA process steps. 
  • Opportunities: The biologics or cell therapies of innovative oncological drugs have a fast track approval process, benefitting the producers significantly. 


South Korea: Strong Compliance to KFDA and the International Standards

The Korea Food and Drug Administration, or KFDA, is in charge of approving all medications in the nation. The organization fully complies with the International Conference on Harmonization's standards and the Good Manufacturing Practices evaluation.  As with the rest of the country, South Korea also has well-regulated biotechnology and biologics sectors, which help to make sure that the manufacturers of oncology drugs adhere to quality standards.

  • Challenges: Even though the KFDA provides a well-integrated regulatory framework, clinical trials for new oncology drugs in South Korea are both costly and time-consuming.
  • Opportunities: Global partnerships are another area of growth, as many international companies are currently partnering with South Korean companies for manufacturing and developing oncology drugs.


4. The Future of Oncology Drug Manufacturing in Asia 

The drug manufacturing industry for cancer treatment is expected to see the most growth in Asia. The region is becoming a key hub for not only cell therapies but also advanced biologics, and even their production and for the supply of biosimilars. Due to increased funding and grants from the government, coupled with higher spending on R&D, there is a shift towards the development of immuno-oncology and personalized therapies. 

As the requirements for certification get easier and the supply of oncology drugs keeps expanding, the function Asia serves in the oncology supply chain on a global scale will keep improving.


5. Conclusion - The Future of Oncology Drug Manufacturing is Asia

With South Korea, China, and India at the forefront, the production of cancer medications in Asia is accelerating. These nations are becoming the focus of international drug developers due to their robust regulatory frameworks and efficient and affordable cancer medication treatments. By knowing the main manufacturers and the compliance requirements, participants can place themselves correctly to take advantage of the oncological opportunities in Asia.
