"We are excited to see the first presentation of data for poziotinib in HER2 exon 20 mutations in NSCLC," said Joe Turgeon, President and Chief Executive Officer of Spectrum Pharmaceuticals. "These data build upon previous results from poziotinib studies and indicate that this drug could be effective in treating both EGFR and HER2 exon 20 mutations. Furthermore, new data from MD Anderson reveal that these mutations are found across a variety of solid tumors and there is strong rationale for evaluating poziotinib in a basket study."
"The pre-clinical and early clinical activity of poziotinib in EGFR and HER2 exon 20 mutant NSCLC suggests poziotinib could be a promising agent for the numerous cancer types driven by HER2 exon 20 mutations," said Jacqulyne Robichaux, Ph.D, Thoracic/Head and Neck Medical Oncology, The University of Texas MD Anderson Cancer Center. "We have previously shown that poziotinib is an effective inhibitor of EGFR exon 20 insertion mutations in vitro and in vivo. These data show that poziotinib overcomes de novo resistance of HER2 exon 20 mutations in NSCLC and other cancers. Further evaluation of poziotinib in solid tumors is warranted."

About Poziotinib
Poziotinib is a novel, Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR TKI) that inhibits the tyrosine kinase activity of EGFR as well as HER2 and HER4. Importantly this, in turn, leads to the inhibition of the proliferation of tumor cells that overexpress these receptors. Mutations or overexpression/amplification of EGFR family receptors have been associated with a number of different cancers, including non-small cell lung cancer (NSCLC), breast cancer, and gastric cancer. Spectrum received exclusive license to develop, manufacture, and commercialize worldwide excluding Korea and China from Hanmi Pharmaceuticals. Poziotinib is currently being investigated by Spectrum and Hanmi in several mid-stage trials in multiple solid tumor indications.

On April 17, 2018 Elios Therapeutics, a biopharmaceutical company developing innovative particle-delivered, dendritic cell vaccines in oncology, reported initial open-label results from the ongoing Phase 2b clinical trial of the TLPLDC (tumor lysate, particle-loaded, dendritic cell) vaccine in patients with stage III and IV (resected) melanoma (Press release, Orbis Health Solutions, APR 17, 2018, View Source [SID1234529911]). Results were presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) 2018 Annual Meeting held April 14-18, 2018 in Chicago, Illinois.

"We are encouraged by these initial open-label results from our Phase 2b trial which demonstrate a compelling safety profile and provide early evidence that the TLPLDC vaccine may enhance the efficacy of commonly used FDA-approved systemic therapies, including checkpoint inhibitors," said George E. Peoples, M.D., chief medical officer at Elios Therapeutics. "We look forward to continuing our assessment of the TLPLDC vaccine in this ongoing study as we evaluate opportunities for further clinical development of combination therapies."

In an ongoing prospective, randomized, double-blind, placebo-controlled Phase 2b trial, patients with resected Stage III and IV melanoma were randomized (2:1) to received either TLPLDC vaccine or placebo to prevent recurrence. All patients who recurred on the trial (met study endpoint) were then offered open-label TLPLDC along with standard of care therapy as determined by the patient’s treatment team.

The initial open-label results presented were from 22 patients. Seven patients had their recurrences resected and were treated with the TLPLDC vaccine to prevent a second recurrence. At 12.5 months of median follow-up, only one patient has recurred.

The remaining 15 patients were on a variety of FDA-approved systemic therapies for their non-resectable recurrences. Of these patients, two patients withdrew from the study and one was not treated. In the remaining 12 patients treated with the TLPLDC vaccine in combination with their standard of care systemic therapy, two patients had a complete response (median follow-up 8.6 months), seven had stable disease and two had progressive disease. One patient progressed initially on TLPLDC vaccine alone but was converted to a complete response once checkpoint inhibitor therapy was initiated. Importantly, the addition of the TLPLDC vaccine did not increase the toxicity of checkpoint inhibitors, BRAF/MEK inhibitors, or TVEC in these patients.

About TLPLDC
The TLPLDC (tumor lysate, particle-loaded, dendritic cell) vaccine is an autologous, personalized, therapeutic cancer vaccine designed to stimulate the immune system to recognize tumor cells and fight a patient’s specific cancer. TLPLDC is made from the patient’s own tumor cells and dendritic cells – the most potent antigen-presenting cells in the body. Once TLPLDC is injected, the tumor lysate-loaded dendritic cells present the tumor antigens to the immune system, stimulating the induction of tumor-specific, activated T cells that are able to find and destroy tumor cells that may remain in the body. TLPLDC is currently being studied as a monotherapy and in combination with standard of care checkpoint inhibitor therapy in a Phase 2b clinical trial for the treatment of late-stage melanoma at leading academic cancer centers in the United States.

On April 17, 2018 NewLink Genetics Corporation (NASDAQ:NLNK) reported that it presented a poster entitled "Indoximod modulates AhR-driven transcription of genes that control immune function" in the Immunomodulatory Agents and Interventions session at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) 2018 Annual Meeting in Chicago (Press release, NewLink Genetics, APR 17, 2018, View Source [SID1234525425]).

"The data demonstrate that indoximod has a unique mechanism of action, remarkably differentiated from IDO enzymatic inhibitors. This different mechanism may contribute to antitumor immune responses in the IDO pathway and through activity independent of IDO," said Charles J. Link, Jr., M.D., Chairman and Chief Executive Officer.

The data suggest that indoximod regulates the differentiation of helper T cells toward an immuno-stimulatory helper function and downregulates genes that control the differentiation of T cells into immuno-suppressive regulatory T cells (Tregs) in an AhR dependent manner. This leads to an increase in the ratio of helper T cells to Tregs. Additionally, it was shown that indoximod reduces the level of IDO protein in dendritic cells in vitro, leading to increased stimulation of CD8 T cell proliferation and reduced production of kynurenine. Moreover, indoximod stimulation of mTOR in T cells appears to increase the proliferation of effector T cells in an IDO and TDO-independent manner. Through this mechanism, indoximod may be able overcome the effects of Trp degradation mediated by both IDO and TDO. Thus, in addition to opposing immunosuppression mediated by the IDO pathway, indoximod may drive antitumor immune responses independent from IDO.

In summary, indoximod has immunostimulatory effects involving 4 main cell types: CD8+ T cells, T helper cells, T regulatory cells, and dendritic cells. Indoximod appears to function through three main mechanisms to inhibit the IDO pathway:

Reversing the effects of low tryptophan by increasing proliferation of effector T cells

Increasing the ratio of T helper to T regulatory cells by both favoring differentiation of activated CD4 T cells into helper T cells and directly reprogramming T regulatory cells into helper T cells

Downregulating IDO expression in dendritic cells

About Indoximod

Indoximod is an investigational, orally available small molecule targeting the IDO pathway. The IDO pathway is a key immuno-oncology target involved in regulating the tumor microenvironment and immune escape. Indoximod is being evaluated in combination with treatment regimens including anti-PD-1/PD-L1 agents, cancer vaccines, radiation and chemotherapy across solid and liquid tumors.

On April 17, 2018 VBI Vaccines Inc. (Nasdaq: VBIV) ("VBI"), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, reported that, upon review of all safety data from the fully enrolled, low-dose patient cohort of the ongoing Phase 1/2a clinical study of VBI-1901 in recurrent Glioblastoma (GBM), the independent Data and Safety Monitoring Board (DSMB) unanimously recommended the continuation of the study without modification (Press release, VBI Vaccines, APR 17, 2018, View Source [SID1234525443]).

Following this recommendation, VBI has initiated enrollment in the intermediate-dose arm of the dose-escalation phase of this study. Two additional, pre-specified DSMB reviews will occur after the completion of enrollment in the intermediate-dose study arm and the high-dose study arm, respectively.
"We are encouraged by the safety profile of this candidate so far and are excited to continue enrollment in the intermediate dose cohort of this Phase 1/2a study, our first clinical study in immuno-oncology," said Jeff Baxter, VBI’s president and CEO. "In recurrent GBM, a devastating CMV-associated tumor, patients have few effective treatment options, and we believe that VBI-1901 has the potential to stimulate immune responses critical to boosting anti-tumor immunity."

About the Phase 1/2a Study Design
VBI’s two-part Phase 1/2a study is a multi-center, open-label, dose-escalation study of VBI-1901 in approximately 28 patients with recurrent GBM:

Part A: Dose-escalation phase to define the safety, tolerability, and optimal dose level of VBI-1901 in recurrent GBM patients. This phase is expected to enroll up to 18 patients in three dose cohorts.

Part B: A subsequent extension of the optimal dose level, as defined in the dose escalation phase. This phase is expected to enroll an expanded cohort of approximately 10 additional patients.
VBI-1901 is administered intradermally and is adjuvanted with granulocyte-macrophage colony-stimulating factor (GM-CSF), a potent adjuvant that mobilizes dendritic cell function. Patients in both phases of the study will receive vaccine every four weeks until tumor progression.
Additional information, including a detailed description of the study design, eligibility criteria, and investigator sites, is available at ClinicalTrials.gov using identifier NCT03382977.
About VBI-1901 and GBM
VBI-1901 is a novel immunotherapy developed using VBI’s eVLP technology to target two highly immunogenic cytomegalovirus (CMV) antigens, gB and pp65. Scientific literature suggests CMV infection is prevalent in multiple solid tumors, and recent research has demonstrated that an anti-CMV dendritic cell vaccination regimen may extend overall survival in patients with GBM. Additionally, recent preclinical studies confirmed that VBI-1901 may be a potent, "off-the-shelf" therapeutic vaccine.
Glioblastoma is among the most common and aggressive malignant primary brain tumors in humans. In the U.S. alone, 12,000 new cases are diagnosed each year. The current standard of care for treating GBM is surgical resection, followed by radiation and chemotherapy. Even with aggressive treatment, GBM progresses rapidly and is exceptionally lethal, with median patient survival of less than 16 months.
