Preliminary Analysis of Recurrent/Metastatic Nasopharyngeal Carcinoma Patients: a Phase II Study

Status:
Active, not recruiting
Trial end date:

Target enrollment:
0
Participant gender:
All
Summary
programmed cell death-1 (PD-1) inhibitors has been recommended as the first-line treatment for recurrent/metastatic nasopharyngeal carcinoma (R/M NPC), but progression-free survival (PFS) and overall survival (OS) was still unsatisfactory. Basic studies have already confirmed PD-1 inhibitors had concurrent synergistic effect with chemotherapy and radiotherapy. Few studies concerned about the treatment pattern for concurrent PD-1 inhibitors combination with chemoradiation for R/M NPC. There was still much uncertainties about the timing, fraction dose and total dose for PD-1 inhibitors combination with radiation. Therefore, we aimed to explore the substantial effect and toxicity of this new pattern for R/M NPC.

Criteria
Inclusion Criteria:

1. Voluntarily participate in the trial and sign the informed consent for the study in
writing.

2. Age ≥ 18 years old (when signing the informed consent for this study).

3. Recurrent or metastatic nasopharyngeal carcinoma confirmed by histopathology.

4. Recurrent and metastatic lesions are not suitable for surgery.

5. According to recist1.1 evaluation criteria, there are measurable lesions (at least 1
measurable lesion).

6. The physical state of the Eastern Cooperative Oncology Group (ECoG) was 0-1.

7. Tumor tissue can be provided for PD-L1 expression detection: newly obtained biopsy
(within 90 days before the start of study treatment) is preferred. If biopsy tissue
cannot be provided for detection, archived tissue wax block can be provided for
post-section detection.

8. Urine pregnancy test was negative (female), and contraceptive measures were taken from
the trial period to 3 months after the end of the trial.

9. The function of main organs is normal, and the blood routine examination shall meet
the following standards: WBC ≥ 4.0 × 109/L,ANC≥2.0 × 109/L, PLT≥100 × 109 / L, Hb ≥
90g / L (no blood transfusion and blood products within 14 days, no correction with
G-CSF and other hematopoietic stimulating factors); Biochemical examination shall meet
the following standards: TBIL ≤ 2.0 × ULN,ALT、AST≤2.5 × ULN, bun and cre ≤ 1.5 × The
clearance rate of ULN or endogenous creatinine ≥ 60ml / min (Cockcroft Gault formula);
Good coagulation function: defined as international normalized ratio (INR) or
prothrombin time (PT) ≤ 1.5 times ULN; If the subject is receiving anticoagulant
treatment, as long as Pt is within the proposed scope of use of anticoagulant drugs;
The myocardial enzyme spectrum was within the normal range.

10. According to the judgment of the investigator, the patient was considered to be able
to comply with the protocol.

Exclusion Criteria:

1. Locally advanced nasopharyngeal carcinoma has disease progression (PD) within 6 months
after systemic treatment.

2. It is known that any component of the investigational drug or preparation has caused
severe hypersensitivity, including severe hypersensitivity to other monoclonal
antibodies, gemcitabine, taxol, fluorouracil, platinum and other related compounds
(NCI ctcaev5.0 ≥ grade 3).

3. According to the criteria of common adverse event terminology (NCI ctcaev5.0), there
were peripheral neuropathy ≥ grade 2.

4. Other malignant tumors occurred within 5 years or present at the same time.

5. Interstitial lung disease or non communicable pneumonia (including past history and
present condition); Local interstitial pneumonia induced by radiotherapy is excluded.

6. Have uncontrolled systemic diseases, including diabetes, hypertension, acute lung
disease, etc.

7. Active infections requiring systemic treatment, including active tuberculosis.

8. Uncontrollable pleural effusion, pericardial effusion or ascites requiring repeated
drainage.

9. There are obvious cardiovascular diseases, heart failure classified as grade 2 or
above by the New York Heart Association (NYHA), previous myocardial infarction within
3 months, unstable arrhythmia (including QT interval ≥ 480 MS) or unstable angina
pectoris.

10. Active central nervous system metastasis and / or cancerous meningitis (before the
first administration, except for patients with stable brain metastases: subjects with
brain metastases who have received previous treatment can participate in the study,
provided that they are clinically stable for at least 2 weeks, there is no evidence of
new or expanded brain metastases, and steroids are stopped 3 days before the
administration of the study drug. Except for subjects with asymptomatic brain
metastases: they have no neurological symptoms, do not need corticosteroids, and have
no lesions > 1.5cm, and they need regular brain tests as disease sites Imaging
examination.)

11. Active hepatitis B or C, meeting any of the following conditions: hepatitis B virus
deoxyribonucleic acid (HBV DNA) in peripheral blood is positive (the result is greater
than the detection limit of the analysis method); Hepatitis C virus RNA (HCV RNA) in
peripheral blood was positive (the result was greater than the detection limit of the
analysis method).

12. Patients with a history of immune deficiency, including HIV positive and / or other
acquired and congenital immune deficiency diseases, and / or patients with a history
of organ transplantation.

13. Active autoimmune diseases that may worsen when receiving systemic steroid therapy or
any other form of immunosuppressive therapy (except for patients with type I diabetes,
vitiligo, psoriasis or hypothyroidism or hyperthyroidism that do not require
immunosuppressive therapy).

14. Immunosuppressive drugs are used, except for the following cases: intranasal, inhaled,
topical steroids or local steroid injections (e.g., intra-articular injections),
physiological doses of systemic corticosteroids (≤ 10 mg / day prednisone or
equivalent dose), steroid pre medication for hypersensitivity reactions (e.g., CT scan
pre medication).

15. Major surgery was performed within 4 weeks before enrollment, and / or there were
unhealed wounds, ulcers or fractures.

16. Live virus vaccine (seasonal influenza vaccine and coronavirus vaccine without live
virus are allowed to be inoculated) was inoculated within 4 weeks before enrollment.

drug trials and receive research treatment or use research devices within 4 weeks
before enrollment.

18. Patients with known drug abuse and / or psychosis have severe intellectual or
cognitive impairment, which may interfere with the cooperation with the trial
requirements.
