About this study

Official title: Evaluate the Efficacy and Safety of HLX10, PD-1 mAb, in Combination With HLX07, EGFR mAb, in Patients With Advanced Head And Neck Tumors

Part1:

A mutilpe-center, open-label, Phase II clinical trial to evaluate the efficacy and the safety of HLX10 in combination with HLX07 in patients with advanced advanced head and neck tumors.

Part2:

A randomized, double-blind, multi-center, phase II clinical study to evaluate the clinical efficacy and safety of HLX10 in combination with HLX07 and chemotherapy versus HLX10 in combination with placebo and chemotherapy in the first-line treatment of R/M HNSCC.

Read the detailed description

Part 1:

This is an open label study. Sample size recommendations for this phase II study are determined according to Simon's two-stage Optimal design.

In the first stage, 13 patients will be accrued. The patients will receive 3 mg/kg of HLX10 every two weeks infusion combined with 600 mg HLX07 weekly (stage 1L). These patients will be assessed for treatment response after 8 weeks of first infusion of study drugs. If there are 3 or fewer responsive patients in these 13 patients, additional 13 patients will be accrued. These additional 13 patients will receive 3 mg/kg of HLX10 every two weeks infusion combined with 800 mg HLX07 weekly (Stage 1H). If 3 or fewer responses after eight weeks treatment noted in these 13 patients in stage 1H, the trial will be stopped.

If 4 or more patients are responsive to therapy in stage 1, the trial will be continued to stage 2, 30 additional patients will be accrued to reach a total of 43 patients. These additional 30 patients will receive the same dose of regimen as the prior patients.

Part 2:

This is a randomized, double-blind, multi-center, phase II clinical study to evaluate the clinical efficacy and safety of HLX10 in combination with HLX07 and chemotherapy versus HLX10 in combination with placebo and chemotherapy in the first-line treatment of R/M HNSCC. Approximately 75 first-line R/M HNSCC subjects are planned to be recruited. The sample size calculation is not based on the statistical hypothesis.

Eligible subjects after screening will be randomly assigned to the treatment group (group A) or the control group (group B) in a ratio of 2:1, with PD-L1 CPS (≥ 20 and < 20) as the stratification factor at randomization (Figure 1):

Group A: approximately 50 subjects, HLX10 in combination with HLX07 and chemotherapy (cisplatin in combination with 5-FU).

Group B: approximately 25 subjects, HLX10 in combination with placebo and chemotherapy (cisplatin in combination with 5-FU).

Cisplatin may be replaced with carboplatin when the subject is judged intolerant to cisplatin by the INV.

The study will be unblinded overall for ORR analysis approximately 3 months after the first dose of the last subject.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing HLX10, HLX07 and Cisplatin/Carboplatin in people with Head and Neck Squamous Cell Carcinoma, run by Shanghai Henlius Biotech at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 26 inclusion and 49 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 8 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part1: Efficacy-ORR (time frame: at 16 weeks after first dose). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04297995, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2023.
