Study summary

Natural killer (NK) cells can kill a broad array of tumor cells in a non-major histocompatibility complex(MHC)-restricted manner. Adoptive transfer of NK may prolong the survival of patients with cancer. This study evaluates the efficacy and safety of NK cell-based immunotherapy for small-cell lung cancer (SCLC) after first-line chemotherapy. Half of the participants will receive autologous adoptive transfer of NK cells after the response from first-line chemotherapy, while the other half will be followed up in routine clinal practice.

Read the detailed description

The small-cell lung cancer (SCLC) is very sensitive to the standard-of-care first-line chemotherapy and/or radiotherapy, but it will ultimately progress or relapse and develop early resistance to conventional treatments. No effective maintenance therapy except for wath and wait after first-line therapy at present.

NK cells constitute the major component of the innate immune system and kill tumor cells in a non-MHC-restricted manner. In our previous pilot study and other reports, adoptive transfer of autologous NK cells expanded ex vivo was very well tolerant and effective.

There is no prospective trial on the maintenance therapy of SCLC after first-line chemotherapy based on autologous NK cells. The purpose of this phase II clinical research is to evaluate the efficacy and safety of autologous NK cells as the maintenance therapy after the first-line treatment, comparing with conventional observation group.

Study arms

  • Experimental
    autologous natural killer cells

    Infusion of 1-2×10\^9 NK cells every 14 days in the absence of progression or unacceptable toxicity until the 6 courses of treatment.

    Biological: NK cells

  • No intervention
    routine follow-up

    According to present guideline, no special treatment is advised for patients with SCLC after first-line therapy.They will be followed-up regularly.

Interventions

  • BiologicalNK cells

    Autologous peripheral blood mononuclear cells (PBMCs) are collected by apheresis on D0, then induced into NK cells and infused into the patients 14 days later (D14) as the initial transfusion. There are 3 consecutive transfusion days (D14-D16). The second course of PBMCs collection started D14 before infusion. A total of 6 courses will be completed unless progression or unacceptable adverse events.

What researchers measure

Primary outcomes

  1. Progression-free survival(PFS)

    Progression-free survival is defined as the time from randomization to first observation of progression or date of death (from any cause). Progression will be evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. Patients who do not progress or not die will be censored on the date of their last tumor assessment, i.e. on the last date that we really know that the patient is considered as "progression-free".

    Time frame: 20 months

Secondary outcomes

  1. Overall survival(OS)

    Overall survival, defined as the time from randomization until death due to any cause. For patients who do not die, time to death will be censored at the time of the last contact.

    Time frame: 20 months

  2. Evaluate the change of the quality of life for all patients

    Patients' quality-of-life will be assessed by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire LC-13 at baseline and after every two courses of adoptive cellular transfer in study group or every visit in control group.

    Time frame: 20 months
