Immunotherapies, particularly PD-1/PD-L1 inhibitors, have revolutionized lung cancer treatment, propelling the global Lung Cancer Therapeutics Market to a 2023 value of $35 billion. These drugs, which unlock the immune system’s ability to attack cancer cells, now account for 35% of total market revenue, a figure projected to rise to 50% by 2030, according to Market Research Future’s analysis. Their success is rewriting survival expectations, with some patients achieving long-term remission where chemotherapy once offered only months of extension.

PD-1 inhibitors like Merck’s Keytruda (pembrolizumab) and Roche’s Tecentriq (atezolizumab) are at the forefront. Keytruda, approved for NSCLC, SCLC, and even adjuvant settings, has seen its sales jump from $1.5 billion in 2018 to $16 billion in 2023, driven by expanding indications. Tecentriq, paired with chemotherapy, extended survival by 4.5 months in PD-L1-negative NSCLC patients, a group previously underserved. Beyond these, newer agents like Bristol Myers Squibb’s Opdivo (nivolumab) are gaining traction in Asia-Pacific, where PD-L1 positivity rates are higher (45% vs. 30% in the U.S.), boosting local adoption. These therapies have transformed late-stage lung cancer from a terminal diagnosis to a chronic condition for many, driving demand.

Yet, adoption faces hurdles. Cost remains prohibitive; Keytruda costs $150,0000 annually, straining public health systems in Europe and limiting access in India, where only 25% of patients can afford it. Side effects, such as immune-related pneumonitis (occurring in 5-10% of cases), also deter clinicians from prescribing in fragile patients. Additionally, small cell lung cancer (SCLC), which lacks targetable mutations, remains resistant to immunotherapy, leaving 15% of patients without precise options. These challenges highlight the need for cost mitigation and complementary therapies.

The future of immunotherapy in lung cancer lies in overcoming these barriers. Biosimilars, like Keytruda copies expected by 2027, could reduce prices by 40%, expanding access. Pharma firms are also developing next-gen immunotherapies (e.g., STING agonists) to tackle PD-1 resistance.
