      Background

      In our recent decade we are seen new drugs coming up with high speed development to attend personalized conditions in lung cancer treatment. After the first TKI for EGFR mutation, many other target drugs such as TKI for ALK/ROS1 alteration, third-generation EGFR TKI, anti-PD-1/PD-L1 immunotherapies bring together an improvement in survival with better quality of life than chemotherapies. But this new specialty drugs are also testing the affordability of the market with new launched ceiling prices. Frequently, their prices have been settled down in a context of an unmet condition appeal rather than the truly health benefits. In pricing it is a common practice to use the external reference price between countries to align the prices based on international market. But if the first price is launched (frequently in USA) in countries that don’t use metrics based on evidence or clinical benefits, the price plateau could be replicated even without necessarily deserving this price. The objective of this presentation is to show the price comparison of drugs included in TKI class and immunotherapy class between high and middle-income countries. Then to compare the cost-treatment of therapies commonly used in advanced lung cancer and their magnitude of clinical benefit.

      All local currencies were converted to US dollars using PPP factor. The magnitude of effect was evaluated based on the ESMO Magnitude of Clinical Benefit Score.

      4c3880bb027f159e801041b1021e88e8 Result

      USA has the highest drug price followed by Brazil, especially in recent launched drugs. Costs of advanced lung cancer treatment significantly increase 5 times more when compared first-generated TKI and new generation TKI. Immunotherapy for second line costs 6 times more than first line with EGFR TKI and could cost more than 7 to 130 times the chemotherapy with docetaxel. Clinical benefits do not reach the same scale.

      8eea62084ca7e541d918e823422bd82e Conclusion

      The market of anticancer drug increasing 10% annually, but clinical benefits don’t advance in the same compass. Specialized drugs come into the market with pricing warrant of unmeet conditions, but if we think in precision medicine all new drug-target biomarker could be priced higher because it will cover a rare or unmet condition. In the context of precision medicine, is it fear a patient pays more because he has a different biomarker for the same clinical condition? If countries do not start to evaluate and pricing drugs based on value, market strategists will continue to test the ceiling price that health systems can(not) afford.

      P2.01-32 - Economic Evaluation of Diagnostic Platforms for T790M Detection in Post EGFR-TKI NSCLC in Brazil (ID 14328)

      16:45 - 18:00  |  Author(s): Luciene Bonan

      Background

      50% of acquired resistance to first or second-generation EGFR-TKIs NSCLC treatment is attributed to T790M mutation. Clinical trials demonstrated superior efficacy of osimertinib versus chemotherapy in second line setting. Nevertheless, the required molecular testing to identify T790M mutation is a challenge considering difficulties related to tissue re-biopsies. Nowadays, availability of noninvasive ctDNA techniques permits safer and faster molecular diagnostic. In Brazil, there are some commercially available tests presenting different accuracy rates. Our objective was to compare current T790M ctDNA tests cost-effectiveness, under local perspective.

      a9ded1e5ce5d75814730bb4caaf49419 Method

      The population is NSCLC post first-line EGFR-TKI progression. Decision tree model started with cfDNA evaluation (RT-PCR based kit, Digital Droplet PCR, or NGS). Due to ctDNA methods intermediate sensitivity, tumor sample analysis is recommended if plasma result is negative. Strategies were a combination of cfDNA tests and RT-PCR based kit or NGS for tumors re-biopsies. Prevalence of T790M mutation, test accuracy, proportion of unknown or unfeasible samples were used to calculate each branch. Tissue re-biopsies complications and costs were also considered. The model was analyzed from a healthcare-payer perspective based on Brazilian private sector.

      4c3880bb027f159e801041b1021e88e8 Result

      Plasma ddPCR then tissue biopsy NGS (if plasma negative) was the most effective, with cost-effective ratio of US$ 3,855.43 per positive T790M detected. Its cost was higher than the second most effective strategy (plasma-NGS + tissue NGS). Incremental cost-effectiveness ratio between both was US$ 21,193.66 per additional positive case detected. All strategies using RT-PCR based kit for plasma and/or tissue were dominated.

      8eea62084ca7e541d918e823422bd82e Conclusion

      In terms of costs and effectiveness, the best algorithms to detect more T790M positive cases are combination of ctDNA (ddPCR or NGS) and NGS test for tumor re-biopsy. ddPCR use followed by NGS permits identification of 5% more T790M mutations than the dominated methods. This study is an effort to optimize expenditures and integrate diagnostics discussions in Brazilian health system.
