A Phase II/III Trial to Evaluate the Efficacy and Safety of QL1706 in Patients With Nasopharyngeal Carcinoma

A Randomized, Open, Multicenter Phase II/III Trial to Compare the Efficacy and Safety of QL1706 and Carrilizumab Combined With Gemcitabine and Cisplatin in First-line Treatment of Recurrent or Metastatic Nasopharyngeal Carcinoma

This is a randomized, open, multicenter phase II/III trial to compare the efficacy and safety of QL1706 and carrilizumab combined with gemcitabine and cisplatin in first-line treatment of recurrent or metastatic nasopharyngeal carcinoma.

Study Overview

• Status: Active, not recruiting
• Conditions: Nasopharyngeal Carcinoma
• Intervention / Treatment: Drug: QL1706; Drug: Gemcitabine; Drug: Cisplatin; Drug: Carrelizumab

Detailed Description

This is a randomized, open, multicenter phase II/III trial to compare the efficacy and safety of QL1706 and carrilizumab combined with gemcitabine and cisplatin in first-line treatment of recurrent or metastatic nasopharyngeal carcinoma. The study is divided into two parts.

The first part is a phase II, single-arm study with an introductory safety phase, which is planned to enroll 30 subjects with nasopharyngeal carcinoma treated with first-line QL1706 in combination with gemcitabine and cisplatin. The primary objective of the first part is to evaluate the safety and tolerability of QL1706 combined with gemcitabine and cisplatin in the first-line treatment of patients with recurrent or metastatic nasopharyngeal carcinoma.

The second part is a phase III randomized, controlled study. The study plans to enroll 430 subjects, who will be randomized in a 1:1 ratio to a trial group of QL1706 in combination with gemcitabine and cisplatin and a control group of carrilizumab in combination with gemcitabine and cisplatin. The primary objective of the second part was to compare the effectiveness of QL1706 with that of carrilizumab combined with gemcitabine and cisplatin, respectively, in the first-line treatment of recurrent or metastatic nasopharyngeal carcinoma.

Eligibility Criteria

• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

1. The subject will participate voluntarily and sign the informed consent form.
2. Age ≥ 18 years when signing the informed consent form, male or female.
3. The Eastern Collaborative Oncology Group (ECOG) physical status score was 0 or 1.
4. Expected survival ≥ 3 months.
5. Patients with pathologically confirmed nasopharyngeal carcinoma.
6. Patients with primary diagnosis of metastatic nasopharyngeal carcinoma [stage IVb according to the American Joint Committee on Cancer AJCC staging system (8th edition)] or patients with recurrent (including recurrent or metastatic) nasopharyngeal carcinoma who are not candidates for radical surgery or radiotherapy or other local treatment; and for recurrent or metastatic lesions must be untreated systemically: previously treated with neoadjuvant chemotherapy with curative intent, Patients with adjuvant chemotherapy, radiotherapy or radiotherapy must have had ≥ 6 months between the last chemotherapy and or radiotherapy and the time of disease recurrence and/or development of metastases.
7. Patients have at least one imaging measurable lesion according to RECISTv1.1 evaluation criteria; for lesions that have received prior radiotherapy or other local treatment there must be evidence of definite progression of the lesion after the end of local treatment in order to be selected as a measurable lesion.

8. Adequate organ function prior to first use of the experimental drug (no blood components, leukocyte-raising drugs, or platelet-raising drugs are allowed within 7 days prior to obtaining laboratory tests)

   1. Absolute neutrophil count ≥ 1.5 x 109/L.
   2. Platelet count ≥ 100×109/L.
   3. Hemoglobin ≥ 90 g/L.
   4. Serum albumin ≥ 28 g/L.
9. Subjects (both female and male) agree to use effective contraception from the time they sign the informed consent until 180 days after the last use of the trial drug. Women who are not pregnant or breastfeeding from the time they sign informed consent until 180 days after the last use of the trial drug.

Exclusion Criteria:

1. Presence of symptomatic central nervous system (CNS) metastases, soft meningeal metastases, or spinal cord compression due to metastases.
2. Prior systemic anticancer treatment with approved drugs or trial drugs.
3. End date of palliative radiotherapy targeting bone metastases or soft tissue, etc. ≤ 7 days from imaging of baseline tumor lesions
4. Presence of carcinomatous meningitis prior to first study treatment
5. Active autoimmune disease present within 2 years prior to the first administration of the investigational drug and requiring systemic systemic therapy. Subjects with relevant alternative therapy who are stable are allowed to be included.
6. Disease requiring systemic treatment with corticosteroids (>10 mg daily prednisone or equivalent) or other immunosuppressive drugs present within 2 weeks prior to first study treatment.
7. At the investigator's discretion, have a serious concomitant condition that jeopardizes patient safety, or interferes with patient completion of the study, such as hypertension (systolic blood pressure ≥ 160 mmHg and/or diastolic blood pressure ≥ 100 mmHg) not controlled by two or more antihypertensive medications, or severe diabetes mellitus.
