Details and patient eligibility

About

NICE-RT study is a "safety run-in" and phase II trial evaluating the safety and efficacy of Camrelizumab combined with Nab-paclitaxel and Carboplatin and Radiotherapy in patients with resectable locally advanced esophageal squamous cell carcinoma.

Full description

Considering that immunotherapy combined with concurrent chemoradiotherapy may have unknown AEs, in order to explore the safety and tolerability of the regimen of camrelizumab combined with nab-paclitaxel and carboplatin and radiotherapy, this study set up an initial "safety run-in" phase. 10 patients will be firstly enrolled, and treatment-related adverse reactions（TRAEs）and surgical complications will be observed at the same time. If the completion rate of neoadjuvant therapy and surgery is greater than 80%, rate of 30-day major complication is less than 20%,and no death, it will continue to enroll 40 patients to explore the efficacy and safety of the regimen. If the completion rate of neoadjuvant therapy and surgery is less than 80%, the MDT will determine whether the study move forward. If treatment related death is more than 1 patients, the study will be terminated.

Enrollment: 50 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Exclusion criteria

1.Pathological type and stage

2. Non resectable or metastatic esophageal cancer

3. Medical history and complications

4. Subjects with any known active autoimmune disease (subjects who have stable clinical symptoms and do not need systematic use of immunosuppressants, such as type I diabetes and hypothyroidism that only need hormone treatment, and skin diseases that do not need systematic treatment can be included).

5. Subjects who have any complications requiring systemic treatment with glucocorticoids such as prednisone (>10mg/day) or who have used immunosuppressive drugs within 14 days before the first administration (subjects who do not have active autoimmune diseases, inhale or locally use glucocorticoids, and who use prednisone (>10mg/day) for hormone replacement treatment of adrenal insufficiency can be included in the group).

6. Subjects have received tumor vaccine or other immune activated anti-tumor drugs (such as interferon, interleukin, thymosin or immunocyte therapy) within 1 month before the first administration.

7. The subject is participating in other clinical trials or has received drug intervention from other clinical trials within 4 weeks before the first administration.

8. Subjects had received surgery or radiotherapy>30Gy within 4 weeks before the first administration.

9. Subjects with other malignant tumors that need to be treated (subjects with skin basal cell carcinoma, skin squamous cell carcinoma, breast cancer in situ or cervical cancer in situ that have received radical treatment and do not need other treatment can be included)

10. Subjects have suffered from serious cardiovascular diseases in the past: myocardial ischemia or myocardial infarction above Grade II, arrhythmia under poor control (including QTc interval ≥ 480 ms); Grade III-IV cardiac insufficiency; Color Doppler echocardiography showed that left ventricular ejection fraction (LVEF) was less than 50%.

11. Subjects have known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation.

12. Subjects received live vaccine within 30 days before the first administration.

13. Laboratory inspection

17. Presence of allergy or hypersensitivity to monoclonal antibodies

18. Allergy or intolerance during infusion

19. Diseases or abnormal laboratory indicators that the investigator believes will affect the research results or are not in line with the interests of the subject should be excluded.
