Details and patient eligibility


This phase 1 trial investigate safety and maximum tolerated dose of natural killer (NK) cells derived from haploidentical family donors in patients with non-small cell lung cancer

Full description

Eligible patients receive pemetrexed 500 mg/m2 intravenously (Day 1). On Day 8, patients receive donor-derived NK cells via a central venous catheter. The NK cell dose is as follows; Level 1: 1.25 X 109 cells Level 2: 2.50 X 109 cells Level 3: 5.00 X 109 cells Three patients each will be treated on each dose level. Two weeks prior to donor NK cell administration to patients, HLA-haploidentical family member of the patients undergo leukapheresis after G-CSF injections to collect hematopoietic stem cells. These donor cells are then taken to the laboratory, where they were differentiated into NK cells ex vivo over approximately over 2-week period.

Inclusion criteria

  • Patients with histologically confirmed non-small cell lung cancer stage 4 (by AJCC 7th)
  • Age, 20 years of age or older
  • ECOG performance status, 0-2
  • Life expectancy ≥3 months
  • Patients should have at least one measurable lesion according to RECIST Criteria v1.1
  • Failure after primary systemic treatment with a regimen including platinum-containing agent (primary systemic treatment may be adjuvant chemotherapy or chemo-radiotherapy, given within 12 months)
  • Adequate bone marrow function (Hb ≥9 g/dL; ANC ≥1,500/uL; and platelet count ≥75,000/uL)

  • Adequate liver function (total bilirubin <1.5 x ULN; AST and ALT <3 x ULN; and ALP <3 x ULN, unless there is bone metastases without evidence of liver disease)
  • Patients should have a suitable HLA-haploidentical family member who is willing to donate hematopoietic stem cells
  • Patients should sign informed consent voluntarily

Exclusion criteria

  • Patients who received anti-cancer chemotherapeutic or biological agents within 3 weeks. Patients who received anti-cancer treatment and did not recover from toxicities to grades 0-1 by NCI CTC AE ver 4.0 are not eligible as well.
  • Patients with contraindication for any medication planned to be administered in the study
  • Patients with significant fluid accumulation in third space (for example, pleural or pericardial effusion) that can not be controlled by drainage
  • Active infectious process
  • Inability to discontinue aspirin over 1.3 g daily or other NSAIDs. Patients cannot take aspirin or NSAIDs within 5 days of pemetrexed administration
  • Major surgery within 4 weeks of study participation
  • Palliative radiation therapy within 1 week of study participation
  • Acute myocardial infarction within 6 months of study participation. History of uncontrolled arrhythmia, symptomatic angina, or symptomatic heart failure
  • Past or current history of CNS metastasis (with exception of those patients who completed treatment of CNS metastasis and not received steroid treatment or whole brain radiotherapy within 2 weeks of screening visit or not received gamma knife treatment within 1 week of screening visit)
  • History of malignancy (other than skin basal cell carcinoma, carcinoma in situ of uterine cervix, or thyroid cancer) within 5 years
  • Pregnant or lactating women. Child-bearing women who are not willing to avoid pregnancy by contraceptives
  • Man not agreeing to contraceptive measures such as condom or abstinence (It is recommended that contraceptive measures be used until 6 months after pemetrexed treatment)
  • Other serious illness or medical condition
