Natural Killer (NK) Cells in Combination With Interleukin-2 (IL-2) and Transforming Growth Factor Beta (TGFbeta) Receptor I Inhibitor Vactosertib in Cancer
Study Details
Study Description
Brief Summary
One of the ways that cancer grows and spreads is by avoiding the immune system.NK cells are immune cells that kill cancer cells, but are often malfunctioning in people with colorectal cancer and blood cancers. A safe way to give people with colorectal cancer and blood cancers fresh NK cells from a healthy donor has recently been discovered. The purpose of this study is to show that using two medicines (vactosertib and IL-2) with NK cells will be safe and will activate the donor NK cells. NK cells and vactosertib are experimental because they are not approved by the Food and Drug Administration (FDA). IL-2 (Proleukin®) has been approved by the FDA for treating other cancers, but the doses used in this study are lower than the approved doses and it is not approved to treat colorectal cancer or blood cancers.

Detailed Description
The objective of this research is to demonstrate that natural killer (NK) cells from non-Human Leukocyte Antigen (HLA)-matched donors can be safely infused into colorectal cancer patients and patients with relapsed/refractory hematologic malignancies in combination with IL-2 and the oral transforming growth factor beta (TGFβ) receptor I inhibitor vactosertib to improve the persistence of donor NK cells.

Drug: Vactosertib
Vactosertib is a highly selective, potent inhibitor of the protein serine/threonine kinase activity of transforming growth factor (TGF)-β receptor type 1 (TGFBR1; also known as activin receptor-like kinase 5 [ALK5]). Vactosertib inhibits the phosphorylation of the ALK5 substrates Smad2 and Smad3, as well as the intracellular signaling of TGF-β.
Other Names:
Drug: Fludarabine Phosphate
Fludarabine phosphate is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoroara-ATP. This metabolite appears to act by inhibiting DNA polymerase alpha, ribonucleotide reductase and DNA primase, thus inhibiting DNA synthesis.
Other Names:
Drug: Cyclophosphamide
Cyclophosphamide is an alkylating agent that prevents cell division by cross-linking DNA strands and decreasing DNA synthesis. It is a cell cycle phase nonspecific agent. Cyclophosphamide also possesses potent immunosuppressive activity.
Other Names:
Drug: IL-2
Proleukin® (aldesleukin) has been shown to possess the biological activities of human native interleukin-2. In vitro studies performed on human cell lines demonstrate the immunoregulatory properties of Proleukin, including: a) enhancement of lymphocyte mitogenesis and stimulation of long-term growth of human interleukin-2 dependent cell lines; b) enhancement of lymphocyte cytotoxicity; c) induction of killer cell (lymphokine-activated (LAK) and natural (NK)) activity; and d) induction of interferon-gamma production.
The in vivo administration of Proleukin in animals and humans produces multiple immunological effects in a dose dependent manner. These effects include activation of cellular immunity with profound lymphocytosis, eosinophilia, and thrombocytopenia, and the production of cytokines including tumor necrosis factor, IL-1 and gamma interferon. In vivo experiments in murine tumor models have shown inhibition of tumor growth
Other Names:
Drug: Natural Killer Cells
Adoptive NK cell therapy has demonstrated the potential for cancer immunotherapy in various malignancies with particular potential in hematologic malignancies including acute myeloid leukemia (AML), and colon cancer [14, 19-23]. This therapeutic approach is extremely well tolerated in patients even when massive numbers of cells are utilized (~109 NK cells/kg). In fact, studies suggest that high doses of NK cells are not only well tolerated but have potential to lead to higher levels of efficacy.

This will be defined as the presence of donor NK cells in recipient blood as determined by STR-chimerism at a frequency of >10%.
- Clinical Response [28 days post-treatment]
This will be defined as a change in size of measurable disease on CT scans (colorectal cancer) or by standard methods for hematologic malignancies (e.g. bone marrow biopsy for AML)
Eligibility Criteria

Inclusion Criteria:
- Subjects must have histologically confirmed locally advanced or metastatic colorectal adenocarcinoma or relapsed or refractory hematologic malignancy and have failed at least one standard line of chemotherapy. Participants will be eligible if they have either refused standard treatment regimens or if there is no standard approach to curative salvage therapy per National Comprehensive Cancer Network (NCCN) guidelines in the setting of relapsed/refractory disease.

Subjects for whom a potential 29-day delay in treatment will interfere with their potential therapeutic options
-
Patients with active, untreated malignant involvement of the central nervous system (CNS) should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Head imaging will be necessary to document absence of active CNS involvement in patients with colon/rectal cancer and soft tissue sarcomas. Patients with hematologic malignancies who have undergone treatment for malignant involvement of the CNS must have no evidence of residual disease by imaging or cerebrospinal fluid (CSF) sampling prior to study enrollment.
-
History of allergic reactions to fludarabine or cyclophosphamide
-
Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
-
Pregnant or breastfeeding women are excluded from this study because cytotoxic agents used as part of the lymphodepleting regimen have the potential for teratogenic or abortifacient effects. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with lymphodepleting chemotherapy, breastfeeding should be discontinued if the mother participates in the trial. These potential risks may also apply to other agents used in this study.
-
HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with chemotherapeutic agents. In addition, these patients are at increased risk of lethal infections when treated with marrow suppressive therapy.

Stem cell transplant recipients will be excluded if they are still receiving immunosuppression including steroids for GVHD or have active GVHD in any organ (except for Grade 1 only of skin, not requiring treatment).
-
Subject who is taking prohibited medications when using vactosertib as following (refer to APPENDIX III). A minimal washout period of 5 half-lives for the following drugs is recommended prior to the first dosing.
