Definitions
- the present invention relates to immunotherapy.
- the present invention provides a pharmaceutical combination and its applications in regulating tumor microenvironment and cancer immunotherapy.
- ICIs immune checkpoint inhibitors
- CTLs cytotoxic T lymphocytes
- PD-1 Programmed cell death protein 1
- PD-L1 Programmed death-ligand 1
- CTLs cytotoxic T lymphocytes
- the primary resistance refers to the condition where no responses occur by the PD-1/PD-L1 blockade. In comparing immunotherapy with chemotherapy or targeting therapy, immunotherapy has relatively high rates of primary resistance, and so the clinical benefit is restricted. It is estimated that about 60%of patients receiving immunotherapy have primary resistance. However, acquired resistance refers to the condition where an initial response to PD-1/PD-L1 blockade occurs with the progression of a disease, and a relapse occurs eventually. It is estimated that about 20%of patients receiving immunotherapy have acquired resistance.
- the low response rates and primary or acquired resistance to PD-1/PD-L1 blockade may be related to the tumor microenvironment (TME) (Annals of Oncology, Volume 27, Issue 8, August 2016, Pages 1492-1504) .
- TAE tumor microenvironment
- the TME is a dynamic and complicated composition that controls tumor immune response.
- the major mechanisms of primary or acquired resistance of PD-1/PD-L1 blockade may include several factors such as TME status, PD-L1 expression, tumor neoantigen expression and presentation, cell signal pathway, immune gene expression, and epigenetic modification.

- the initial ORR assessments were performed 3 days after the last drug administration, however the second ORR assessments were additionally scheduled 10 days after the last drug administration due to the observation of continuous tumor shrinkage.
- Treatment with anti-CTLA-4 Ab combined with Regorafenib plus Chidamide-k30 group was significant in boosting ORR from 62.5%to 87.5%and augmenting CR from 5 to 7 mice in the second assessment in the mice with primary resistance to first-line anti-PD-1 Ab therapy.

- the immunity was defined as negative, when it met two conditions: the tumor volume was over 300 mm 3 , or the tumor size was over 2 fold when compared to baseline. If the immune memory was activated after treatment, the immunity was active and specific to the recognition of the cancer cells with the same antigen and the growth of tumors inoculated during the rechallenge would be inhibited, therefore the immunity was defined as positive. If the immune memory was not induced or not fully activated, resulting in the growth of tumors inoculated during the rechallenge (tumor recurrence) , then the immunity would be defined as negative.

Anti-Colorectal Cancer Activity in Animal Models. Animal study was approved and overseen by The Taipei Medical University Institutional Animal Care and Use Committee (TMU IACUC, NO: LAC-2020-0103, LAC-2019-0644) . Six-to eight-week-old male Balb/c mice (Laboratory Animal Center, Taiwan, China) were used for all animal experiments. CT26 cell line was purchased from ATCC. CT26 tumor cell lines were grown in RPMI-1640 supplemented with 10% (vol/vol) FBS at 37 ℃, 5%CO 2. Tumors were established by s. c. injection of 1×10 6 CT26 cells with Matrigel (354248, ) into the left flank of mice, and growth determined by measuring two perpendicular diameters.
