Modified tumor-infiltrating lymphocytes or TIL therapies have emerged as a viable and potent option to selectively eradicate the tumor population, with minimal side effects. Till date, several clinical trials have demonstrated the efficacy and therapeutic superiority (over conventional treatment options) of TIL-based therapies. Their tumor-cell killing efficiency is attributed to the fact that they are pre-sensitized to cancer specific antigens.
Ongoing and planned clinical research initiatives in this direction are driven by encouraging results achieved in past trials, which were mostly focused on various hematological cancers and solid tumors. Driven by the ongoing pace of innovation in the TIL cell therapy domain, sufficient financial support from investors and encouraging clinical trial results, the TIL therapies market is likely to witness significant growth in the foreseen future.
Current Market Landscape of TIL Cell Therapy
Over 75 TIL immunotherapies are being evaluated across different stages of preclinical / clinical development, either as monotherapies or in combination with other drugs. Both industry and non-industry players have demonstrated keen interest in the development of novel TIL-based cell therapy products. Further, melanoma emerged as the most popular target indication in this domain. More than 95% of the therapy candidates that are being developed to target a wide range of disease indications are autologous in nature.
Driven by a promising development pipeline of the T-cell therapy market and encouraging clinical trial results, the TIL-based therapy market is likely to carve out a significant share of the multi billion-dollar cancer immunotherapy market.
Rising Interest in TIL Therapies
The growing interest in this field is therapies is reflected from the increase in the partnerships focused on R&D of such therapies. Several investors, having realized the opportunity within this upcoming segment of T-cell immunotherapy, have invested USD 2.7 billion, across 30 instances, since 2013. Further, in the last 10 years, close to 95 clinical trials evaluating TIL therapies have been registered across different geographies for the evaluation of TIL therapies.
Mostly driven by the need for effective treatment options for cancer, the TIL-based therapy pipeline is expected to steadily grow over the coming years.
