I notice a lot of the people are from Oxigene.
Do you remember that we had a JV with Oxigene on Vascular Targeting Agents many years ago? I believe Macular Degeneration was one indication but CJ could probably give us more color on that.

another possible collaboration re: ROR1 and ROR2

Kancera strengthens patent rights related to ROR antibody therapy

About ROR
ROR is a family of receptor tyrosine kinase receptors originally reported to be linked to fetus development and consists of two receptors, ROR1 and ROR2. Today it is also known that ROR receptors play a role also for cancer cells. It has been shown that inhibition of ROR causes certain cancer cells to eliminate themselves through apoptosis. Since ROR receptors are not present in healthy cells in adults, it is anticipated that a drug targeting ROR will selectively attack the tumor much more forcefully than healthy tissue.

Kancera’s co-founder Professor Håkan Mellstedt has shown that Kancera´s ROR inhibitors are capable of killing cancer cells originating from pancreas and as well as leukemic cells. Professor Mellstedt and other scientists have further shown that ROR is a potential therapeutic target also in prostate-, breast- and lung cancer.

so the puzzle gets bigger but at least we have a tie from Hakan Mellstedt to Gerald McMahon CEO of Kolltan...




.... so "dozens of collaborations.." were told months back and months later we find out the #1 cancer hospital => Sloan Kettering was on board fully re: PS Targeting in immunotherapy and now, we have MSK at this event, along with Chairman Jeff Hutchins (Peregrine KOL) and also Kolltan .... wonder how many more puzzle pieces come out of this event...

Cambridge Healthtech Institute’s Second Annual
Rational Combination Cancer Immunotherapy

Designing and Implementing Strategies for Increasing the Efficacy of Cancer Immunotherapy by Combining Checkpoint Inhibitors and Biotherapeutics


August 25-26

8:30 Immune Checkpoint Modulation: Rational Design of Combination Strategies

Michael A. Postow, M.D., Assistant Attending Physician, Melanoma and Immunotherapeutics Service, Memorial Sloan-Kettering Cancer Center

The immune system can be manipulated to enhance antitumor immunity. Efficacy has been demonstrated by approaches that block immune checkpoints, but not all patients benefit from treatment and improved outcomes are needed. Therapeutic approaches combining multiple immune checkpoint inhibitors with standard anticancer agents (radiotherapy, targeted therapy, and chemotherapy) are of great interest. Current approaches and a framework for the future will be discussed.

9:00 Expansion and Activation of T Cells via the Targeting of the Immunosuppressive Ligand Phosphatidylserine (PS): Combination Strategy with Conventional, Targeted, and Checkpoint Inhibitor Therapy

Jeff T. Hutchins, Ph.D., Vice President, Preclinical Research, Peregrine Pharmaceuticals

The underlying cause for the failure of current therapies is the persistent and multifocal immune suppression in the tumor microenvironment that drives the absence of pre-existing antitumor T cells. Bavituximab blocks PS-mediated immunosuppression (decreasing MDSCs) by reprograming immune cells in the tumor microenvironment to enhance anticancer activity. Pre-clinical, translational, and clinical results using bavituximab with conventional and immunotherapy combinations promotes a robust, anti-tumor T cell mediated response to enhance cancer therapy.

11:30 The TAM Receptor Tyrosine Kinase Family and Their Potential to Modulate Macrophage and Dendritic Cell Function Create Opportunities to Combine with T Cell Checkpoint Drugs

Jerry McMahonJerry McMahon, Ph.D., President & CEO, Kolltan Pharmaceuticals

TAM receptor tyrosine kinases and their cognate ligands play a key role in immune homeostasis through signaling in macrophage and dendritic cells and regulating the adaptive immune response. Modulation of the activation of these receptors may up- or down-regulate immune homeostasis for the treatment of cancer and other diseases. Inhibition of Axl and MerTK are under investigation to potentiate the effectiveness of biologic agents that interfere with T cell checkpoints in tumor immunology.

Hakan Mellstedt : Peregrine Pharmaceuticals KOL

.... ok, so lately we've brought in some puzzle pieces for Greg Lemke <> Xetrios <> Salks Institute and a PS Targeting Patent and all other associated patents of Lemkes's and Salks all sold to "Kolltan"

so the puzzle gets bigger but at least we have a tie from Hakan Mellstedt to Gerald McMahon CEO of Kolltan...and PAV lists of some have shown Standish Fleming as well

...
...

I post this, because I remember the very first time I seen that Greg Lemke/Salk was studying/researching PS Targeting and the first time I seen Phosphatidylserine written as "PtdSer" was with Salks publications by Greg Lemke. Anyhow, as you can see all their patents / research..etc was purchased by KOLLTAN.

Kolltan CEO McMahon speaks a couple hours after Jeff Hutchins next week and notice how it states "..and their cognate ligands" ?? Seems like it could be referring to PS receptors and all that PS Targeting research that fell in the hands of Kolltan and now Kolltan one of the very few at this conference must truly know that PS Targeting is required for that optimal immune response.
