A Dose Escalation Phase I Study to Assess the Safety and Clinical Activity of Multiple Cancer Indications
THINK (THerapeutic Immunotherapy with NKR-2) is a multinational (EU / US) open-label Phase I study to assess the safety and clinical activity of multiple administrations of autologous NKR-2 cells in seven refractory cancers, including five solid tumors (colorectal, ovarian, bladder, triple-negative breast and pancreatic cancers) and two hematological tumors (acute myeloid leukemia and multiple myeloma).
- Main inclusion criteria are: - Men or women ≥ 18 years old at the time of signing the ICF, - Patient with a CRC, epithelial ovarian cell or fallopian tube carcinoma, urothelial carcinoma, TNBC, pancreatic cancer, AML/MDS or MM, - Disease must be measurable according to the corresponding guidelines, - Patient with an ECOG performance status 0 or 1, and AML patients with anemia resulting in an ECOG performance status of 2, - Patient with adequate bone marrow reserve, hepatic and renal functions. - Patients must have sufficient pulmonary functions with a Forced Expiratory Volume in the first second (FEV-1)/Forced Vital Capacity (FVC) ≥ 0.7 with FEV-1 ≥ 50% predicted. Main exclusion criteria are: - Patient with a tumor metastasis in the central nervous system, - Patients who have received another cancer therapy within 2 weeks before the planned day for the apheresis (except hydroxyurea for AML patients), - Patients who receive or are planned to receive any other investigational product within the 3 weeks before the planned day for the first NKR-2 administration (except hydroxyurea for AML patients), - Patient is under systemic immunosuppressive drugs, unless specific cases authorized per protocol, - Patients who have received other cell therapies, - Patients who underwent major surgery within 4 weeks before the planned day for the first NKR-2 administration. - Patient cannot present with history of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis and/or active or acute exacerbation of chronic obstructive pulmonary disease (COPD). Detailed disease specific criteria exist and can be discussed with contacts listed below.

Trial Objectives and Outline
This open-label Phase I study aims at assessing the safety and clinical activity of the NKR-2 treatment administered 3 times with a 2-week interval between each administration in different tumor types. In absence of progressive disease at the first tumor assessment following NKR-2 administratio, the patient will receive a new cycle of 3 administrations maximum with a 2-week interval. The study will contain two consecutive segments: a Phase I dose escalation and a Phase I expansion segment. The Phase I dose escalation segment will include 2 arms, one in solid tumors and one in hematological tumors. The dose escalation design will include 3 dose levels: The dose escalation phase will consist of 3 cohorts (Cohorts 1-3) for the solid tumors, and 3 cohorts (Cohorts 4-6) for the hematological tumors; with each set of 3 cohorts receiving escalating doses of the NKR-2 therapy. Two additional cohorts will be added in each dose escalation arm with the aim to provide a more intense treatment during the induction treatment. These additional cohorts in both the solid arm (cohort 8-9 - only in CRC) and in the hematological arm of the study (cohort 10-11 - only in AML/MDS) will therefore evaluate a tighter schedule of NKR-2 injections with the three first injections within the induction cycle separated by a 1-week interval followed two weeks later by a second cycle (cycle 2) with a 2-weeks interval between each three NKR 2 injections. These cohorts will each enroll 3 patients in case of no DLT. Based on safety and early clinical data from these cohorts, the specific schedule of cohorts 8-11 might be selected for the expansion.
