Description:
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).

Purpose
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).
Detailed Description
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.
Trial Arms
Name | Type | Description | Interventions |
---|
Hematological tumors | Experimental | The dose escalation arm for hematological tumors will use a 3 +3 design to determine the maximum tolerated dose. Two additional cohorts will be added in this dose escalation arm with the aim to provide a more intense treatment during the induction treatment (cycle 1 of injection). Cohort 10-11 (only in AML/MDS) will evaluate a tighter schedule of NKR-2 injections at 1x109 or potentially 3x109 NKR-2 per injection with the three first injections within the induction cycle (cycle 1) 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. | |
Solid Tumors | Experimental | The dose escalation arm for solid tumors will use a 3 +3 design to determine the maximum tolerated dose. Two additional cohorts will be added in this dose escalation arm with the aim to provide a more intense treatment during the induction treatment (cycle 1 of injection). Cohort cohort 8-9 ( only in CRC) will evaluate a tighter schedule of NKR-2 injections at 1x109 or potentially 3x109 NKR-2 per injection with the three first injections within the induction cycle (cycle 1) 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. | |
