View original scientific description
The purpose of the research is to test the safety and efficacy of the investigational drug in human subjects with cancer.
Interventions
DRUG
Toripalimab
Toripalimab will be administered 240 mg intravenously every three weeks in combination with the induction chemotherapy regimen for 3 cycles, and for 9 cycles as adjuvant treatment following radiation as specified in the overall sequential treatment plan.
RADIATION
Concurrent Chemoradiation and Adjuvant treatment following Chemoradiation
Radiation treatment will be initiated 3-6 weeks following day 1 of the last induction cycle using institutional standards of care and support as follows: Intensity modulated radiotherapy, 70 Gy in 33 fractions M-F once daily plus cisplatin 40 mg/m2 IV weekly for up to 7 doses. Following the completion of concurrent chemoradiation, capecitabine will be administered using institutional standards of care as follows: Capecitabine 650 mg/m2 PO BID x 12 months beginning 12 to 16 weeks following the end of radiation treatment. Dose reductions and discontinuance of capecitabine will be according to the standard of care applied at the treating institution. Adjuvant Toripalimab 240 mg IV q 21d x 9 maximum doses will be initiated concurrently with the initiation of adjuvant capecitabine, beginning 12-16 weeks following the end of radiation.
Primary outcome measures
Induction chemotherapy completion rate
Time frame: 3 years
Induction chemotherapy completion rate, defined as the proportion of patients who complete three cycles of chemoimmunotherapy within 12 weeks of initiation. Completion is defined for induction as receiving all 3 cycles as planned, including protocol specified dose reduction and delays. .
Radiation completion rate
Time frame: 3 years
Radiation completion rate, defined as the proportion of patients who complete specified radiation within 8 weeks of radiation initiation. Radiation completion is defined as completion of planned doses of radiation.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Eligible disease(s) / stage(s): Locoregionally advanced EBV positive NPC (T3-4, any N OR any T, N1-3. No M1) per AJCC v 8
- Prior therapy: None for NPC permitted
- Life expectancy: 3 months at least
- Contraception requirements: Women of childbearing potential and male participants who are sexually active must agree to use a medically effective means of birth control during treatment with toripalimab and for 4 months after the last dose.
- ECOG Performance Status of 0,1, or 2
- Age: At least 18 years old. CBC/differential obtained within 21 days prior to day 1 of treatment, with adequate bone marrow function defined as follows:
- Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3
- Platelets ≥ 100,000 cells/mm3;
- Hemoglobin ≥ 8.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥ 8.0 g/dl is acceptable.); Adequate hepatic function within 21 days prior to day 1 of treatment, defined as follows:
- Total bilirubin ≤ 1.5 x institutional ULN;
- AST and ALT ≤ 1.5 x institutional ULN; Adequate renal function within 21 days prior to day 1 of treatment, defined as follows:
- Serum creatinine ≤ 1.5 mg/dl or calculated or measured creatinine clearance (CC) ≥ 50 ml/min
- Negative serum pregnancy test within 14 days prior to day 1 of treatment for women of childbearing potential
- Ability to understand and the willingness to personally sign the written IRB approved informed consent document.
Exclusion criteria
- Prior systemic anticancer treatment for NPC
- Prior radiation to head and neck region or regions necessitating overlapping fields
- Concurrent use of any anti- cancer treatment, standard, alternative or investigational.
- History of allergic reactions to any agents in this study
- Autoimmune disease or organ transplant which in the judgment of the PI would increase the risk of immune checkpoint inhibition.
- Pregnant or breastfeeding
- Severe, active co-morbidity, defined as follows:
- Major medical or psychiatric illness, which in the investigator's opinion would interfere with the completion of therapy and follow up or with full understanding of the risks and potential complications of the therapy;
- Unstable angina and/or uncontrolled congestive heart failure within past 6 months;
- Myocardial infarction within the last 6 months;
- Current acute bacterial or fungal infection requiring intravenous antibiotics; note that patients receiving IV antibiotics or currently on oral antibiotics whose infection is assessed to be adequately treated or controlled are eligible.
- Chronic Obstructive Pulmonary Disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy within 30 days prior to day 1 of treatment;
- Acquired Immune Deficiency Syndrome (AIDS) based upon current CDC definition; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive
- Patients with hearing loss assessed to be primarily sensorineural in nature, requiring a hearing aid, or intervention (i.e. interfering in a clinically significant way with activities of daily living); a conductive hearing loss that is tumor-related is allowed
- ≥ grade 2 peripheral sensory neuropathy
Where
- Palo Alto, California

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
