Neoantigen-expanded Autologous Immune Cell Therapy

• Status: Recruiting
• Trial end date: 2023-06-30
• Target enrollment: 0
• Participant gender: All

Summary

The investigators aim to investigate the patient's tumor neoantigen to generate "personalized cancer vaccine" and then to expand autologous dendritic cells-cytokine-induced killer cells (DC-CIK). The autologous DC-CIK will be cultured in vitro and re-infused into patients.

• Phase: Phase 1

12. Patient with malignant sarcoma must have received first-line chemotherapies or target therapies.

13. Patient with breast cancer who are unable to undergo surgery must have received anthracycline taxsnes and any third-line medication.

14. Patient with ovarian cancer must have received platinum-containing chemotherapies to stop recurrence within 1-6 months; or have done more than the 2nd-line chemotherapies.

15. Patient with cervical cancer must have received radiation therapy and chemotherapies.

16. Patient with endometrial cancer must have received hormone therapy or radiotherapy.

17. Patient with lung cancer must be refractory to the first-line standard treatment contained with platinum-based doublet chemotherapy in the patient without detected driver mutation or have failed to tyrosine kinase inhibitors and standard platinum-based doublet chemotherapy in those with drug related driver mutation.

18. Patient with brain cancer must have received radiation therapy and chemotherapies; or patient's tumor still recurs within one to six months after chemotherapies, andcan not be completely resected; or patients have failed to target therapies.

6. Clinical performance status of ECOG 0 or 1.

7. Life expectancy exceeds six months

8. Patients can take foods and drugs orally.

9. Hematology:

1. Absolute neutrophil count greater than 1000/mm3 without support of filgrastim

2. Normal WBC (> 3000/mm3).

3. Hemoglobin greater than 8.0 g/dl. Subjects may be transfused to reach this cut-off.

4. Platelet count greater than 100,000/mm3

5. Normal prothrombin time (less than or equal to 15.2 seconds)

10. The heart, lung and liver function of the patient must comply with:

1. NYHA (the New York Heart Association) Functional Class I or II

2. Serum ALT / AST is less than 150 U/L (patients with advanced hepatocellular carcinoma need to be less than 180 U/L)

11. Patient with primary major surgery needs to have elapsed ≥ 4 weeks prior to the planned first study treatment day.

12. Patient who has ever received chemotherapy, radiotherapy or immunotherapy (anti-CTLA4 or anti-PD1/PDL1), or biologic therapy (anti-VEGF or anti-TKR) modalities need to washout ≥ 4 weeks prior to the baseline visit.

Exclusion Criteria:

1. Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the treatment on the fetus or infant.
