简要总结
Small-Cell Lung Cancer (SCLC) accounts for 10% to 15% of new lung cancers and is a highly aggressive neuroendocrine tumor. In the past 30 years, the treatment of SCLC has made very limited progress, and basically made breakthroughs in radiotherapy and chemotherapy. With the advent of the immune era, immunotherapy has achieved initial results in the treatment of SCLC. Approximately one-third of patients with small cell lung cancer are in limited-stage (LS-SCLC) disease at first diagnosis. Except for a very small number of patients with T1-2N0 who can be treated with surgery or stereotactic radiation therapy (SBRT), the standard treatment for the rest of the patients with LS-SCLC is concurrent chemoradiotherapy. The ORR of platinum-combined etoposide regimen combined with thoracic radiotherapy in LS-SCLC can reach 70% to 90%, and the median OS is 16-24 months, which significantly improves the survival of patients. Although many measures have been taken in the treatment of LS-SCLC, only 20% of LS-SCLC can be cured, and most patients have relapse and metastasis after treatment. This study is a single arm phase II preliminary pilot study, aim to assess the efficacy and safety of durvalumab combined with EP prior to CRT and followed by durvalumab consolidation therapy for LS-SCLC.

入选标准
- •1.Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
- •2.Histologically or cytologically confirmed small cell lung cancer
- •3.Limited-stage, defined as stage I-III SCLC (T any, N any, M0). Patients who are Stage I or II must be medically inoperable as determined by investigator.
- •4.Age > 18 years.
- •5.Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- •6.Adequate normal organ and marrow function.
- •7.Must have a life expectancy of at least 12 week.
- •8.At least 1 lesion, not previously irradiated, that qualifies as a RECIST 1.1 target lesion (TL) at baseline. Tumor assessment by computed tomography (CT) scan or magnetic resonance imaging (MRI) must be performed within 28 days prior to enrollment.
排除标准
- •1.Patients with extensive disease small-cell lung cancer.
- •2.Patients who previously received radiotherapy to the thorax or chemotherapy for small cell lung cancer.
- •3.Any previous diagnosis of transformed non-small cell lung cancer (NSCLC), epidermal growth factor receptor (EGFR) activating mutation positive NSCLC that has transformed to SCLC, or mixed SCLC NSCLC histology. Patients with mixed histology tumors with predominant SCLC histology are allowed.
- •4.Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values.
- •5.Any concurrent chemotherapy other than study treatment, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.
- •6.History of allogenic organ transplantation.
- •7.Active or prior documented autoimmune or inflammatory disorders.
- •8.Uncontrolled intercurrent illness.
- •9.History of leptomeningeal carcinomatosis.
- •10.Mean QT interval corrected for heart rate using Fridericia's formula (QTcF) ≥470 ms calculated from 3 ECGs (within 15 minutes at 5 minutes apart)
- •11.History of active primary immunodeficiency
- •12.Known active hepatitis infection, positive hepatitis C virus (HCV) antibody, hepatitis B virus (HBV) surface antigen (HBsAg) or HBV core antibody (anti-HBc), at screening. Participants with a past or resolved HBV infection (defined as the presence of antiHBc and absence of HBsAg) and with undetectable HBV DNA (< 10 IU/ml or under the limit of detection per local lab standard) are eligible. Participants positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
- •13.Receipt of live attenuated vaccine within 30 days prior to the first dose of IP.
- •14.Prior treatment in a previous durvalumab clinical study.
- •15.Known allergy or hypersensitivity to IP or any excipient.
