Market Dynamics

Global Companion Diagnostics Market Drivers:

Growing Significance of Personalized Medicine

Personalized medicine is a process that tailors medical treatment according to the distinct attributes of individual patients. Personalized medicines are precise and tailored to individual patients for enhanced treatment based on the body's response and illness susceptibility. Personalized medicine can potentially improve patient outcomes and quality of life while mitigating therapy's negative effects and expenses. Companion diagnostics play a crucial role in personalized medicine by aiding in selecting the optimal treatment and dosage for individual patients, considering their genetic profile or biomarker expression. 
Companion diagnostics can also aid in the surveillance of treatment response and resistance, facilitating therapy adjustment as necessary. In 2016, the Tailored Medicine Coalition (PMC) reported that 20% of the novel molecular entities authorized by the FDA were tailored medications. Consequently, the increasing popularity of personalized medicine is expected to propel the expansion of the global market.

Rising Incidence of Cancer and Growing Adoption of Targeted Therapies

Cancer is a prominent contributor to global mortality and morbidity, impacting millions of individuals annually. The World Health Organization (WHO) reported that there were approximately 19.3 million new instances of cancer and 10 million deaths caused by cancer in the year 2020. Targeted therapies are pharmaceutical agents that selectively target the molecular aberrations responsible for promoting the proliferation and viability of cancerous cells. 
Furthermore, targeted therapies provide cancer patients with treatment choices that are more efficient and less harmful than traditional chemotherapy and radiation. However, it is important to note that only some patients respond favorably to identical targeted medication, and some individuals may eventually acquire resistance. Companion diagnostics help find resistance mutations and identify patients who mostly benefit from a specific targeted therapy. In the near future, it is expected that the growing use of targeted therapies and the rising incidence of cancer will propel the companion diagnostics market's growth.

Global Companion Diagnostics Market Restraint:

High Cost of Immunotherapy Treatment

Immunotherapy is a therapeutic approach that harnesses the body's innate immune system to combat cancer. Immunotherapy has shown considerable potential as a cancer therapy, but its exorbitant price has limited patient availability. Alternatively, physicians may integrate therapies, prolonging the therapy time from five months to more than three years. In this case, the cost increases proportionally with the duration. 
Furthermore, personalized immunotherapies come with a high cost. For instance, KYMRIAH, the authorized CAR T-cell therapy developed by Novartis, and YESCARTA, created by Gilead Sciences, have a price range of USD 373,000 to USD 475,000 per patient, varying based on the specific form of cancer being treated. Immunotherapies for cancer can incur considerably higher costs compared to alternative treatment methods, such as chemotherapy or radiation therapy. Hence, the exorbitant expenses associated with immuno-oncology treatments are expected to impede the growth of the global market.

Global Companion Diagnostics Market Opportunities:
