Brief Summary

This is a single-arm，open-label study to evaluate the efficacy and safety of tislelizumab plus chemotherapy for conversion therapy of patients with locally nonresectable ESCC.

Conditions

Esophageal Squamous Cell Carcinoma; Locally Advanced Carcinoma

Keywords

Drug: Tislelizumab; Chemotherapy

Outcome Measures

Primary Outcomes (3)

• Incidence of translational treatment AE

  Translational treatment-related AEs resulted in rates of surgery that were more than 30 days late or inoperable than originally planned

  up to 2 years

• MPR

  The proportion of patients whose primary tumor cell residual was less than 10% in the total number of patients enrolled after transformation therapy

  up to 2 years

• pCR

  Pathological complete response refers to that no tumor component or a small amount of carcinoma in situ component can be found on the horizontal line of pathological section after systemic treatment and surgical resection of the lesion.

  up to 2 years

Secondary Outcomes (2)

• R0 resection rate

  up to 2 years

• Disease-free Survival，DFS

  up to 2 years

Study Arms (1)

Tislelizumab plus Chemotherapy

EXPERIMENTAL

In the single experimental arm, patients with locally nonresectable disease were subjected to receive neoadjuvant tislelizumab (200mg) plus chemotherapy (FP regimen) for conversion therapy. If conversion therapy succeeds, patients would proceed to surgery and adjuvant therapy. Otherwise, if patients were still not resectable after the conversion therapy, they will be treated by tislelizumab plus chemotherapy with or without palliative radiotherapy .

Drug: Tislelizumab; Drug: 5-FU; Drug: cis Platinum

Interventions

Tislelizumab DRUG

The 1st to 3rd doses were administered concurrently with FP regimen chemotherapy, 200 mg Tislelizumab each, on D1, D22 and D43 by intravenous infusion. In patients with successful conversion, one dose of 200 mg was administered 21 days after surgery in concurrent with the 4th to 6th cycles of 5-Fu, then 6 cycles of 200 mg Tislelizumab as adjuvant therapy; in patients with failed conversion, chemotherapy combined with tislelizumab were administered, with or without radiation therapy.

Tislelizumab plus Chemotherapy

5-FU DRUG

A FP regimen with 5-Fu 850mg/m\^2 d1-4 + cis-platinum 850mg/m\^2 d1-4 was used, on D1, D22 and D43 infused intravenously. 3 cycles of 5-Fu 850mg/m\^2 d1-4 adjuvant chemotherapy were started at 21 days after surgery in patients with a successful conversion. In patients with failed conversion, chemotherapy combined with tislelizumab were administered, with or without radiation therapy.

Tislelizumab plus Chemotherapy

cis Platinum DRUG

A FP regimen with 5-Fu 850mg/m\^2 d1-4 + cis-platinum 850mg/m\^2 d1-4 was used, on D1, D22 and D43 infused intravenously. In patients with failed conversion, chemotherapy combined with tislelizumab were administered, with or without radiation therapy.
