About NLG207

NLG207 (formerly CRLX101) is an investigational nanoparticle-drug conjugate (NDC) composed of a cyclodextrin-based polymer backbone conjugated to camptothecin, a topoisomerase-1 inhibitor. NDCs enhance drug delivery to tumors where gradual payload release inside cancer cells augments antitumor activity while reducing toxicity. Topoisomerase 1 inhibitors are a class of drugs that modify DNA damage responses in cancer cells. NewLink Genetics is evaluating NLG207 in a series of clinical trials in advanced refractory ovarian cancer patients.

ALX Oncology to Present Preclinical Data on SIRPα Antibody Program at Upcoming Conferences

On February 27, 2019 ALX Oncology, a clinical-stage immuno-oncology company developing therapies to block the CD47 checkpoint mechanism, reported that preclinical data for its SIRPα antibody research program will be presented at the 2019 Keystone Symposia Conference (Keystone), Cancer Immunotherapy in Whistler, British Columbia and the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2019 in Atlanta, Georgia (Press release, ALX Oncology, FEB 27, 2019, View Source [SID1234533751]).

CD47/SIRPα interaction is a key checkpoint mechanism exploited by cancer cells to escape immunological surveillance. While CD47 is widely expressed in human cells, SIRPα, the CD47 inhibitory receptor, is mainly expressed in myeloid cells and neurons. ALX148, a CD47 blocker with an inactive Fc domain, is generally well tolerated and demonstrates anti-cancer activity in combination with trastuzumab and pembrolizumab in patients with anti-HER2 and checkpoint inhibitor resistant/refractory disease (SITC 2018, P335). Another approach to block this interaction is to target SIRPα.

"Targeting the CD47/SIRPα pathway is an exciting new approach that shows promise in clinical trials. By targeting SIRPα, we can investigate the similarities and differences of an orthogonal strategy to inhibit this axis," said Hong Wan, Ph.D., ALX Oncology’s Chief Scientific Officer. "Our panel of proprietary high affinity monoclonal antibodies provides diverse epitope coverage across the extracellular surface of SIRPα. These antibodies are cross-reactive to human, monkey and rodent SIRPα variants, which enables robust clinical translation. Importantly, these antibodies bind to all human SIRPα variants, a critical attribute for a global patient population."

ALX Oncology’s SIRPα antibodies enhance the antitumor activity of immune checkpoint inhibitors, with reduction of metastases, eradication of tumors, and acquisition of memory immune response in tumor-bearing mice with intact immune systems. The cellular immune response in syngeneic models shows that these SIRPα antibodies enhance innate and adaptive anti-cancer immunity, providing a rationale for combination with other immunotherapies. In an exploratory toxicology study in monkeys, the selected SIRPα antibodies demonstrate a favorable pharmacokinetic, target occupancy and tolerability profile.

Together, these preclinical data provide a compelling rationale to advance the development of anti-SIRPα therapy for patients with cancer.

The presentation will describe the use of a preclinical pancreatic mouse model to study the effects of LDOS47 alone or in combination therapies. This model was generated by modifying a mouse pancreatic cancer cell line (Panc02) to express the human ceacam6 antigen that is recognized by L-DOS47. The model is designed to be used for monotherapy L-DOS47 efficacy studies and for combination studies with various agents, including immunotherapies. In addition, to therapeutic studies, the model may also be helpful in studying the effects of L-DOS47 in modifying tumor pH and the tumor immune environment. The presentation will describe the development of the cell line, generation of tumor grafts, and show responses to L-DOS47 in combination with doxorubicin treatments. The usefulness of the model, including difficulties of this model, will also be described. This work is part of an on-going collaboration with Moffitt and is being performed to support the clinical development of L-DOS47 and the DOS47 platform.

"I would like to thank Dr. Robert (Bob) Gillies and the Moffitt team on leading this work" said Heman Chao, Helix’s Chief Executive Officer. "Following on the excellent safety and tolerability results from the Phase I monotherapy lung cancer study in Poland and continuing good progress made with the U.S. Phase I LDOS47 combination study with pemetrexed and carboplatin, we are very excited to launch the pancreatic program and expand the clinical application of L-DOS47."

About Indoximod

Indoximod is an investigational, orally available small molecule targeting the IDO pathway. The IDO pathway is a key immuno-oncology target, suppressing immune response and allowing for immune escape by degrading tryptophan with the resultant production of kynurenine. Indoximod reverses the immunosuppressive effects of low tryptophan and high kynurenine through mechanisms that include modulation of the AhR-driven transcription of genes that control immune function. This results in increased proliferation of effector T cells, increased differentiation into helper T cells rather than regulatory T cells, and downregulation of IDO expression in dendritic cells. Indoximod is being evaluated in combination with treatment regimens including chemotherapy, radiation, checkpoint blockade and cancer vaccines across multiple indications including recurrent pediatric brain tumors, DIPG, and AML.
