Anti-PD-1 and CTLA-4 Combination Therapy for Chemoresistant NSCLC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-small cell lung cancer (NSCLC) is relatively insensitive to chemotherapy, and existing immunotherapies using PD-1 and CTLA-4 inhibitors have not been extensively tested in combination for efficacy in lung cancer types beyond melanoma.
Innovation Solution
Administering a combination of anti-PD-1 and anti-CTLA-4 antibodies, such as nivolumab and ipilimumab, to patients with NSCLC, either sequentially or concurrently, in specific dosing regimens to enhance antitumor activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemotherapy is used to treat non-small cell lung cancer, then treatment is administered, but the cancer is relatively insensitive to chemotherapy
Solution Approach 1:
The patent changes the treatment parameter from chemotherapy to immunotherapy by administering anti-PD-1 and anti-CTLA-4 antibodies, thereby overcoming the chemoresistance of NSCLC and achieving durable clinical responses in patients who did not respond to conventional chemotherapy
2Reliability
If PD-1 inhibitor alone is administered, then treatment is provided, but antitumor activity is limited
Solution Approach 1:
The patent combines two different immunotherapeutic agents (anti-PD-1 antibody and anti-CTLA-4 antibody) into a single treatment regimen, thereby synergistically enhancing antitumor activity and achieving durable clinical responses that are superior to either agent alone
3Reliability
If combination immunotherapy is administered, then treatment outcomes improve, but treatment complexity increases
Solution Approach 1:
The patent establishes predetermined dosing regimens and administration schedules for the combination therapy, with specific dosing intervals and sequences that simplify the complex treatment protocol while maintaining the durable clinical responses achieved through combination immunotherapy

AI summary
This disclosure provides a method for treating a subject afflicted with a lung cancer, which method comprises administering to the subject therapeutically effective amounts of: (a) an anti-cancer agent which is an antibody or an antigen-binding portion thereof that specifically binds to a Programmed Death-1 (PD-1) receptor and inhibits PD-1 activity which can be administered by infusion for less than 60 minutes; and, optionally, (b) another anti-cancer agent which is administered by infusion for less than 90 minutes. The other anti-cancer agent can be an anti-Cytotoxic T-Lymphocyte Antigen-4 (CTLA-4) antibody.
