About this trial

This is an interventional treatment trial for Advanced Cancers focused on measuring Advanced cancer, Plasmodium immunotherapy, Plasmodiun vivax

Eligibility Criteria

18 Years - 70 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • 18-70 years of age, male or female.

  • Patient compliance meets the need for follow-up;
  • The subjects are able to understand and sign informed consent.

Exclusion Criteria:

  • Patients with severe hemoglobin disease or severe G6PD deficiency;

  • With the following diseases or conditions: newly diagnosed with CNS metastasis ( excluding that the tumor lesions of the CNS has disappeared after treatment) and serious or uncontrolled systemic disease or any unstable systemic diseases (including but not limited to active infection, grade three hypertension, unstable angina, congestive heart failure, class III or IV heart disease, severe arrhythmia, liver and kidney dysfunction or metabolic disease), a clear history of neurological or psychiatric disorders, etc;
  • Accept any other anti-tumor treatment at the same time;
  • Patients with significantly lower immune function than those in the normal population;
  • Lung function is seriously damaged, the MNW <39% or can't get out of bed, still feel short of breath when resting;

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Blood-stage infection of P.vivax

Arm Description

This is a single arm study that plans to enroll 20 patients and each patient will be vaccinated with P. vivax-infected red blood cells containing approximately 0.3-1.0 × 10^7 Plasmodium parasites. And successful infection will be indicated by microscopic observation of parasitemia in peripheral blood samples. The treatment will last 3-6 months from the day of successful infection and will be terminated by antimalarial drugs.

Outcomes

Primary Outcome Measures

Number of participants with treatment-related adverse events as assessed by NCI CTCAE 4.0
Adverse events will be evaluated according to NCI CTCAE 4.0, and the incidence of adverse events will be calculated.

Secondary Outcome Measures

Progression free survival
Progression free survival (PFS): Starting from treatment until the disease progression is first found or the time of any cause of death (disease progression refers to tumor growth, or metastasis of primary tumor, or discovery of new lesions).
Overall survival
The time starting from the treatment to death of whatever causes (when subjects have lost for follow-up before death, the last follow-up time will be calculated as the time of death).
Tumor marker level
The patient's sensitive tumor markers will be reviewed periodically from the time they are enrolled into the study.
Objective response rate (ORR)
The proportion of patients whose tumor is reduced to a certain amount and maintain a certain period of time.
Quality of life
Patients are regularly filled with QLQ-C30 (cancer patient quality of life scale) to assess the quality of life of the patients.
1 year of survival rate
The number of cancer cases remaining after 1 year of treatment / the total number of cancer cases treated * 100%.
2 year of survival rate
The number of cancer cases remaining after 2 years of treatment / the total number of cancer cases treated * 100%.
Immunological index
Detection of absolute number of immune cells(such as CD3+CD4+、CD3+CD8+ and so on )in peripheral blood by flow cytometry.

5. Study Description

Brief Summary
The purpose of this study is to evaluate the safety of Plasmodium immunotherapy and preliminarily evaluate the effectiveness of Plasmodium immunotherapy for advanced cancers.The treatment will last 3-6 months from the day of successful infection and will be terminated by antimalarial drugs.
Detailed Description
This study is to enroll 20 patients. Each patient will be vaccinated with P. vivax-infected red blood cells containing approximately 0.3-1.0 × 10^7 Plasmodium parasites and be observed for the exact infection time, parasitemia condition and infection course; principal clinical symptoms such as fever; gastrointestinal reaction; peripheral blood parameters;heart, liver and kidney function; changes in lung function, and dynamic changes in the function of peripheral immune cells. Moreover, the tolerance of patients to Plasmodium infection and changes in tumor-related parameters will be observed preliminarily.The duration of the planned treatment of each subject is 3-6 months. Since the successful infection will be indicated by microscopic observation of parasitemia in peripheral blood samples, the time of the treatment course is based on the presence of peripheral parasitemia. After 3-6 months, parasitemia will be terminated by antimalarial drugs for terminating the treatment of Plasmodium immunotherapy ( the immunological treatment effect may persist after the termination of Plasmodium infection).
