Checkpoint Inhibitor Refractory Cancer Market Size - Analysis

Checkpoint Inhibitor Refractory Cancer Market Trends

With significant advances being made in the area of cancer immunotherapy, checkpoint inhibitors have emerged as an important treatment option for various types of cancer. Checkpoint inhibitors work by blocking certain proteins made by some types of immune system cells, known as 'checkpoints', that can keep the immune system from attacking cancer cells.

With rising incidents of various cancer types globally, the number of patients diagnosed with cancers resistant to checkpoint inhibitors is steadily increasing. As per medical experts, around 40-50% of cancer patients develop resistance to initial checkpoint therapy. This highlights the clear unmet need to develop novel therapies effective for cancers not responding to current immunotherapy options. The large patient pool unable to benefit from standard checkpoint inhibitors is driving significant focus on research and development of new drugs targeting treatment resistance.

Market Driver - Advances in Personalized and Combination Therapies Boosting Treatment Efficacy

One approach gaining momentum is using biomarkers to identify patients most likely to benefit from certain combinations. For example, tumors with high microsatellite instability have been shown to respond very well to checkpoint inhibitors. Similarly, PD-L1 testing helps identify patients with PD-L1 positive tumors that may respond favorably to PD-1/PD-L1 targeted therapies.

Early clinical evidence suggests these personalized, rational combination strategies are helping overcome resistance and improve outcomes for more patients compared to single agent therapies alone. Continued advances in this area are expected to transform treatment paradigms and boost efficacy for cancers unresponsive to existing checkpoint inhibitor options.

While checkpoint inhibitor therapies have shown promising results in certain cancer settings, several critical challenges remain in delivering these emerging treatment options to all patients in need. One major hurdle is the exorbitantly high cost of many immunotherapies currently available or in late-stage development.

Furthermore, most payers rarely approve alternative immunotherapies once patients have progressed on first-line treatment due to comparative lack of evidence, high costs and affordability constraints. This leaves a significant portion of refractory cancer patients with no good treatment options. Additional research is urgently required to develop lower cost combination or sequential regimens that can achieve comparable or better efficacy outcomes at affordable prices.

Market Opportunity - Ongoing Clinical Trials Exploring Novel Combination Therapies and Alternative Immunotherapies

Combining agents with complementary immune modulating mechanisms, like CTLA-4 and PD-1/PD-L1 inhibitors, holds potential for synergistic anti-tumor effects. Alternative approaches being assessed include immunotherapies targeting new checkpoints like LAG-3, TIGIT, TIM-3 and IDO1. Several trials are also repurposing existing immunotherapies in refractory settings to leverage known safety profiles.

Prescribers preferences of Checkpoint Inhibitor Refractory Cancer Market

For first-line treatment of refractory metastatic cancers, prescribers commonly prescribe a combination of Opdivo (nivolumab) or Keytruda (pembrolizumab), checkpoint inhibitors, along with chemotherapy drugs like Alimta (pemetrexed) or carboplatin. This approach aims to synergistically boost the immune response along with reducing tumor size.

For third-line therapy and beyond, treatment selections are largely based on individual case factors like specific mutations, organ dysfunction, co-morbidities, and performance status. Defactinib in combination with chemotherapy may be explored for KRAS-mutated cancers. Alternatively, prescribers may offer clinical trial enrollment if a suitable option is available. Palliative care is prioritized to maximize quality of life once standard options are exhausted.

Treatment Option Analysis of Checkpoint Inhibitor Refractory Cancer Market

Checkpoint inhibitor refractory cancer is a difficult stage of disease where initial immunotherapy has failed. There are few remaining options that offer the potential for response. The line of treatment and tumor characteristics help determine the best approach.

When both immunotherapy and chemotherapy options are exhausted, the disease is considered late-stage refractory cancer. Clinical trials of novel agents remain important here, but aggressive local therapies may provide benefit with minimal side effects if limited metastases are present. Stereotactic radiosurgery has shown promise for controlling selected brain metastases. Ablative techniques like radiofrequency ablation can sometimes control liver or lung tumors.

Key winning strategies adopted by key players of Checkpoint Inhibitor Refractory Cancer Market

Focus on combination therapies: Most major players have focused on developing combination therapies that pair checkpoint inhibitors with other treatment modalities like chemotherapy, targeted therapy etc. For example, Merck & Co. developed Keytruda (pembrolizumab) in combination with chemotherapy for gastric cancer. In a Phase 3 KEYNOTE-062 trial, the combo doubled median overall survival compared to chemotherapy alone.

Partnering with Bio-techs: Bio-techs have novel targets and mechanisms that large pharma can commercialize. AstraZeneca has partnered with other firms, yielding successful drugs. For example, in 2017, it partnered with Daiichi Sankyo on ENHERTU. In a Phase 3 trial, ENHERTU doubled progression-free survival vs. trastuzumab emtansine in HER2-positive metastatic breast cancer.

Segmental Analysis of Checkpoint Inhibitor Refractory Cancer Market

In terms of therapy, immune checkpoint inhibitors is likely to hold 54.3% revenue share of the checkpoint inhibitor refractory cancer market owning to its effectiveness against various refractory cancer types. Immune checkpoint inhibitors work by blocking proteins made by some types of immune system cells, called T-cells, that act like brakes on the immune system and stop it from attacking the cancer cells.

Its ability to induce durable responses has increased its uptake even in later lines of therapy. Ongoing clinical trials evaluating immune checkpoint inhibitors alone and in combination for other cancer types are further expanding its addressable market.

In terms of cancer type, lung cancer is expected to contribute 38.7% of the checkpoint inhibitor refractory cancer market owing to its high prevalence and mortality rates globally. Lung cancer is the second most common cancer but the leading cause of cancer-related deaths worldwide. A majority of lung cancers are diagnosed at an advanced stage when the disease has become refractory to initial treatments.

In terms of treatment line, first-line treatment contributes the highest share of the checkpoint inhibitor refractory cancer market owing to the large patient pool eligible for initial therapies. While cancers like lung cancer often present at an advanced stage, first-line treatment still represents the largest segment as it includes all newly diagnosed patients.

Additional Insights of Checkpoint Inhibitor Refractory Cancer Market

A significant number of patients develop resistance to checkpoint inhibitors, with an estimated 156,370 incident cases of refractory cancer types in the 7MM in 2020, highlighting a critical area of unmet need.
