Innovative CAR-T Cell Therapy Trials in Multiple Myeloma
Aurigene Oncology Limited, a dedicated biotech firm wholly owned by Dr. Reddy’s Laboratories Limited, has unveiled groundbreaking results from its Phase 1 study concerning Ribrecabtagene autoleucel (DRL-1801). This study marks a significant milestone as India’s very first clinical trial focusing on a novel autologous CAR-T cell therapy specifically designed for treating multiple myeloma.
Clinical Study Highlights
The trial, known as the SWASTH study, revealed initial developments involving eight patients who had faced extensive pre-treatment, with an average of 5.5 prior treatment regimens. Many of these patients had undergone transplants previously and experienced disease progression thereafter. Notably, a remarkable 100% of the participants achieved a clinical response, and 62.5% attained what is termed a stringent complete response.
Safety and Efficacy Observations
From a safety perspective, the study reported no incidents of high-grade Cytokine Release Syndrome (CRS) or neurotoxicity among any of the patients. This excellent safety profile, combined with the promising efficacy results, is generating excitement within the medical community, particularly for those specializing in hematology and oncology.
Regulatory Approval and Next Steps
Following the promising Phase 1 results, the Drugs Controller General of India (DCGI), the country’s regulatory body, has officially approved the initiation of Phase 2 trials. These results were recently shared at a prestigious gathering, the 21st annual meeting of the International Myeloma Society, taking place in Rio De Janeiro, Brazil. The global recognition of the trial results underscores the significant impact of this research on the treatment landscape for myeloma patients.
Comments from Leadership
Dr. Murali Ramachandra, CEO of Aurigene Oncology Limited, expressed enthusiasm about the findings. He stated, “The results from the trial in heavily pre-treated relapsed refractory myeloma patients are very exciting for us in India. We are thrilled with the data, as the drug could be transformative for Indian patients with myeloma.” Such endorsements highlight the potential this therapy has to change lives and improve treatment outcomes.
About the Therapy and Its Development
Ribrecabtagene autoleucel employs a cutting-edge CAR-T approach. This treatment utilizes a humanized single-domain antibody that serves as the antigen binding domain and integrates a lentivirus as a vector. The manufacturing of DRL-1801 for ongoing clinical trials occurs at Aurigene's specialized CAR-T GMP manufacturing facility located in Bangalore. This dedicated facility signifies the company’s commitment to quality and innovation in cancer therapy.

Frequently Asked Questions
What is CAR-T therapy?
CAR-T therapy is a form of cancer treatment where a patient's T-cells are modified to attack cancer cells more effectively.
How does Ribrecabtagene autoleucel work?
This therapy targets the BCMA antigen found on multiple myeloma cells, prompting the immune system to destroy these cancerous cells.
Why are the trial results significant?
The results indicate a high response rate and safety in heavily pre-treated patients, suggesting potential for broader use in multiple myeloma therapy.
What is the next step for this clinical trial?
The regulatory approval for Phase 2 has been granted, allowing further exploration and evaluation of the therapy's efficacy.
What other developments is Aurigene pursuing?
Aurigene is actively developing multiple assets, including novel inhibitors for immune checkpoint proteins and targeted therapies for various cancers.
