Avicentrix

Rockville, Maryland, US

We are an immunology-centric research lab committed to unlocking the power of the immune system across a wide range of diseases.

We help our partners de-risk research and development decisions by providing evaluating immune-mediated mechanisms across broad disease areas. We do this by:

  • De-risk biology and mechanism and action.
  • Understand the cross talk between cell and disease biology.
  • Leverage existing and prospective data sets to paint a holistic picture.

Our access to samples, tools and a fully functional lab enables us to be flexible in the design and implementation of assays and systems.

Avicentrix has not listed any services.

HLA-Matched CTL and Tumor Cell Lines

We now have access to a unique set of HLA-matched CTL and tumor lines (colon cancer). These are well characterized lines and useful in confirming tumor lysis by drug candidates by specific/matched CD8 T cells.

We offer a number of assays including:
1. CTL assays for a quick evaluation of tumor killing
2. Flow cytometry and cytokine based readouts
3. Target expression and binding studies using tumor lines
4. Integrate additional immune cells i.e. NK, Tregs etc. to evaluate ability to suppress/proliferate CTL

Tumor-infiltrating lymphocytes are white blood cells that have left the bloodstream and migrated into a tumor. They are mononuclear immune cells, a mix of different types of cells (i.e., T cells, B cells, NK cells, macrophages) in variable proportions, T cells being the most abundant cells. In this assay, we will use a melanoma TIL and tumor from the same patient. This patient is non-responsive to KEYTRUDA (anti-PD-1) therapy. The purpose of this assay is to study how well a drug candidate will perform in a Keytruda non-responsive line.

Study Design

Melanoma TIL and tumor are co-cultured for 24 hours
Study arms will include
Anti-PD-L1 – positive control
Keytruda (anti-PD-1) – 10ug/ml concentration – negative control
Drug candidate
No drug candidate (control)
Assay run in triplicates
Readouts measured:

IFNγ
Number of drug candidates to be tested = 5

Client Provides

Drug candidate at 5ug/ml or equivalent concentration
Material handling instructions
Deliverable

Price includes the delivery of the raw data files obtained directly from the instrumentation (e.g. Luminex, Flow cytometer etc.,)
Price does not include analysis of the raw data. Client will be responsible for analysis.

Cancer – HDAC inhibition assay on a KEYTRUDA non-responder TIL and tumor line

Study Rationale
Studies have recently shown that therapies targeting the epigenetic regulatory family of histone deacetylases (HDACs) have demonstrated success in the treatment of certain hematologic malignancies. HDAC inhibitors have shown to enhance anti-tumor immune responses. Studies have shown that certain HDAC classes may up-regulate the expression of PD-L1 in solid tumors.

Tumor-infiltrating lymphocytes are white blood cells that have left the bloodstream and migrated into a tumor. They are mono-nuclear immune cells, a mix of different types of cells (i.e., T cells, B cells, NK cells, macrophages) in variable proportions, T cells being the most abundant cells. In this assay, we will use a proprietary, HLA-matched melanoma TIL and tumor to study the effects of HDAC targeting drug candidates in the presence and abscence of Keytruda. We will also compare the results with two approved HDAC inhibitors – Zolinza (Vorinostat -approved for CTCL) and Kyprolis (Panobinostat – approved for multiple myeloma)

Cell Lines
We will use a TIL and tumor cell line derived from a patient that did not respond to Keytruda (anti-PD-1) therapy. The characterization profile of this unique cell line is as follows:

TIL expression: TIM-3, TIGIT, CD27, 4-1BB, GITR, PD-1, CTLA-4, LIGHT, CXCR1, CXCR2

Tumor expression: HVEM, B7-H4, CSF-1R, GITRL, 4-1BBL, CD70, CD155

Study Design
Melanoma TIL and tumor are co-cultured for 24 hours
Assay run in triplicates
Single dose study
Study arms will include:
Zolinza(Vorinostat) + TIL + Tumor
Zolinza(Vorinostat) +Keytruda (anti-PD-1) + TIL + Tumor
Kyprolis (Panobinostat) + TIL + Tumor
Kyprolis (Panobinostat) + Keytruda (anti-PD-1) + TIL + Tumor
Keytruda (anti-PD-1) + TIL + Tumor

Readouts measured:
Cytokines: IL-2, IL-4, IL-5, IL-9, IL-10, IL-13, IL-17, and IFN-γ.

JAK inhibition assay on a KEYTRUDA non-responder TIL and tumor line

JAK inhibition assay on a KEYTRUDA non-responder TIL and tumor line

Study Rationale
Studies have recently shown that acquired resistance to PD-1 blockade in patients with advanced melanoma can be associated with loss-of-function mutations with loss of heterozygosity in JAK1/2 or in beta 2-microglobulin. Genetic studies on melanoma and colon cancer samples have shown loss-of-function mutations of JAK1 and JAK2 that may lead to defects in interferon gamma receptor signaling and in turn absence of PD-L1 expression. This assay is designed to evaluate the combination of JAK inhibitors with Keytruda (anti-PD-1) to determine whether this combination approach can overcome resistance/non-responsiveness.

Tumor-infiltrating lymphocytes are white blood cells that have left the bloodstream and migrated into a tumor. They are mono-nuclear immune cells, a mix of different types of cells (i.e., T cells, B cells, NK cells, macrophages) in variable proportions, T cells being the most abundant cells. In this assay, we will use a proprietary, HLA-matched melanoma TIL and tumor from the same patient to test JAK inhibitors in the presence and absence of Keytruda. We will compare the results to an approved JAK inhibitor – Jakafi® Ruxolitinib.

Cell Lines
We will use a TIL and tumor cell line derived from a patient that did not respond to KEYTRUDA (anti-PD-1) therapy. The characterization profile of this unique cell line is as follows:

Our calendared assay program offers our clients a cost effective approach in generating additional, value-add datasets for their immuno-modulatory programs beyond the current indication strategy. Immuno-modulatory drugs lend themselves to broad spectrum disease applications. As a result, our calendared assay program is designed to afford our clients an opportunity to cost effectively obtain additional data points without distracting internal resources.

Our team compiles a list of immune mediated assays each month and lists them on our online calendar. If you like or are interested in an assay, you may use our website or Science Exchange to place a reservation. By partnering with Science Exchange, we offer a streamlined approach for client to sign up and send their drug candidates - hassle free.

KEYTRUDA (anti-PD-1) resistant TIL and tumor line

Tumor-infiltrating lymphocytes are white blood cells that have left the bloodstream and migrated into a tumor. They are mono-nuclear immune cells, a mix of different types of cells (i.e., T cells, B cells, NK cells, macrophages) in variable proportions, T cells being the most abundant cells. Studies have shown that certain immune checkpoint molecules are up-regulated in response to checkpoint therapy and may play a role in mediating resistance.
We use a TIL and tumor cell line derived from a patient that did not respond to KEYTRUDA (anti-PD-1) therapy. The characterization profile of this unique cell line is as follows:
TIL expression: TIM-3, TIGIT, CD27, 4-1BB, GITR, PD-1, CTLA-4, LIGHT, CXCR1, CXCR2
Tumor expression: HVEM, B7-H4, CSF-1R, GITRL, 4-1BBL, CD70, CD155

Studies conducted with this cell line:
1. Flow cytometry analysis of cell surface markers (i.e. checkpoints) in response to drug candidate
2. Cytokine readouts in response to drug candidate
3. Studying macrophages, Tregs sub-populations and their changes in response to drug candidate
4. Mechanisms of resistance to Keytruda (anti-PD-1)
5. 3D assays to study chemokines and chemokine receptors.
6. Other mechanism, function and biology based questions in IO
