Avant Diagnostics Appoints Philippe Goix, PhD, MBA as President & CEO to Commercialize Proprietary Theralink(R) Tumor Biomarker Platform

Dr. Goix brings 20 years of successful healthcare commercialization experience

Two posters were presented at ASCO June 3rd, 2017 for Theralink® Breast Cancer


GAITHERSBURG, Maryland, June 21, 2017 -- (Healthcare Sales & Marketing Network) -- Avant Diagnostics, Inc. ("Avant") (OTC: AVDX), an oncology-focused medical solutions company developing the proprietary Theralink® phospho-protein tumor biomarker platform, announced the appointment of Philippe Goix, PhD, MBA as President & CEO. Dr. Goix brings to Avant a successful track record of product launches and commercial success in health IT, biomarker/diagnostics and commercial laboratory settings.

"The Theralink technology represents a uniquely valuable and wholly complementary tumor biomarker strategy to various biomarker techniques currently in use, including DNA sequencing," said Dr. Goix, the newly appointed President & CEO of Avant. "While we acknowledge the tremendous value that genomic information has added to the field of oncology, we believe Theralink potentially provides additional actionable personalized tumor information on the individual patient level. We believe this additional specificity delivers superior clinical utility for practitioners than genomic information alone, and may lead to improved treatment outcomes for patients. As a result, we intend to evaluate commercial opportunities to leverage this unique patient-centric approach using Theralink as a critical point of market entry. We intend to build personalized solutions that provide the necessary information for physicians to make real-time, best-in-class treatment recommendations as well as recommend wellness solutions designed to improve overall outcomes based upon personal functional clinical data."

Dr. Goix brings to Avant 20 years of experience in the Life Sciences tools, Diagnostics and Health Information areas, where he has raised over $140M in debt and equity capital. Most recently, Dr. Goix served as President & CEO of Prism Health Diagnostics, Inc. (PHDX), which he co-founded in late 2015 to establish ongoing wellness monitoring services as a business by delivering biomarker data to primary-care physicians and consumers to empower consumers to make better health decisions. Dr. Goix left PHDX in March of 2017to pursue the opportunity with Avant. Prior to PHDX, Dr. Goix consulted for several healthcare companies from 2013 to 2015. Between 2004 through 2013, Dr. Goix served as President & CEO of Singulex, Inc., a personalized healthcare diagnostics company focused on improving outcomes in the $300B diabetes-cardiovascular space. While at Singulex from 2004-2013, Singulex grew from annual revenues of $0 and 4 employees, to annual revenues of over $60M and over 250 employees. During his tenure, Dr. Goix built a business comprising of three divisions: a laboratory testing division under CLIA, a proprietary pharma services division and an FDA-focused diagnostic development division. From 1997 to 2004, Dr. Goix served as President & CEO of Guava Technologies, Inc. where Dr. Goix successfully commercialized multiple commercial products still in use today. Guava Technologies was acquired by Merck Millipore in 2008.

In academia, Dr. Goix served as a research scientist at Stanford University, Lawrence Livermore Laboratory, Sandia Research Laboratory and Centre National de Recherche Scientifique in France. Dr. Goix was also a post-doctoral fellow at UC Berkeley. Dr. Goix received his PhD in Physics from Universite de Rouen in France in 1987, and his MBA in Marketing with a Finance emphasis from University of San Francisco in 1995.

Former CEO Gregg Linn has resigned from the Company and the Board of Directors. Former Directors Randy Letcavage and Joe Roth have also resigned from the Company.

Abstract:

Background: AR is expressed in the majority of BCs and its signaling may contribute to the development of BC metastases (mets). The expression pattern of AR, its phosphorylated form, p-AR S650, and correlations with other BC growth and survival pathways were evaluated in BC mets by reverse phase protein array (RPPA). Methods: RPPA was performed on 93 FFPE primary BCs and mets at a CLIA-certified laboratory. Immunostaining with 24 antibodies was directed against AR, p-AR S650, p-MET, and total and p-HER1/2/3 pathway proteins. Clinical and genomic data were obtained from pt chart review. Analysis of variance (ANOVA) was used to assess any statistically significant differences between the groups. Results: 35 tissues were primary BCs (38%); 58 were mets (62%). Sites of mets: liver (n = 41); lung (n = 8); chest wall (n = 9). Of the 41 liver mets, 2 were triple negative (TN), 32 were ER+/HER2-, and 7 were HER2+. AR expression was increased in chest wall (1.7-fold; p = 0.038) compared to primary BCs. p-AR was increased in liver (2.0-fold; p = 0.039) and chest wall (1.8-fold; p = 0.026) compared to primary BCs. ER+ liver mets especially showed strong liver-specific activation of AR along with overexpression of HER1, HER3, VEGFR, and activation of mTOR, S6 Ribo, 4EBP1, and STAT3. MEK/ERK pathway was not activated in ER+ liver mets. HER2+ liver mets had pan-HER1/2/3 activation along with MET, SRC, S6 Ribo, 4EBP1, and JAK2/STAT3. In the 2 TN liver mets, EGFR, VEGFR, mTOR, S6 Ribo, 4EBP1, and JAK2/STAT3 were activated while AR and MEK/ERK were not. The ER+ liver mets showed higher expression of p-AR (p = 0.079), p-HER3 (p = 0.002), p-HER2 (p = 0.010) and p-Jak2 (p = 0.002) compared to primary ER+ BCs whereas the HER2+ liver mets showed lower level of p-IGFR (p = 0.049) and p-MET (p = 0.010) compared to primary HER2+ BCs. Interestingly, TN chest wall mets had higher levels of AR and p-AR (p = 0.008 and 0.044 respectively) compared to TN BCs. Conclusions: ER+ liver mets have strong expression of AR and p-AR, and all liver met subtypes showed accumulation of S6 Ribo/4EBP1 and activation of JAK2/STAT3, but not the MAPK pathway. HER1/3 and HER1/2/3 were activated in ER+ and HER2+ liver mets, respectively. These data suggest that targeting AR, HER1/3, and mTOR in ER+ liver met would be of interest.

Title: Phosphoproteomic analysis of matched primary breast cancer (BC) and lymph node (LN) metastases - ( http://abstracts.asco.org/199/AbstView_199_183025.html )

Abstract:

Background: Therapeutic recommendations are often based on molecular markers expressed in primary BCs. However, LN metastases (mets) may more accurately reflect the lethal potential of the disease (Ries 2007). Whether activated oncogenic pathways in axillary LN mets can be reliably identified in the associated primary BCs is unknown. We evaluated the activation of key signaling pathways in pts' matched primary BC and axillary LN mets using reverse phase protein array (RPPA). Methods: 60 pts' matched FFPE primary BC and axillary LN mets (20 TN, 20 ER+/HER2-, 20 HER2+) are to be evaluated by RPPA at a CLIA-certified laboratory. The first 20 matched BC/LN (3 TN, 14 ER+/HER2-, 3 HER2+) and 7 unmatched (1 TN LN, 1 ER+/HER2- BC, 5 ER+/HER2- LN) results are reported here. Immunostaining of 14 HER1/2/3 and downstream pathway proteins was performed. Mann-Whitney U tests (p value) were utilized to compare BC vs LN mets protein level. Results: Increased expression of HER1 (6-fold) and p-Akt (2-fold) was observed in TN compared to Luminal (Lum) and HER2+ primary BCs. AR expression was upregulated in TN and HER2+ (2-fold) compared to Lum primary BCs. The LN mets showed higher expression of HER1 (p = 0.004), p-HER3 (p = 0.040), p-IGFR (p = 0.009), p-S6 (p = 0.033), p-4EBP1 (p = 0.027) and p-MEK1/2 (p = 0.023) compared to primary BCs. TN had higher level of p-Akt T308 (p = 0.077) in the LN mets compared to the primary BCs while HER2+ showed a downregulation of p-Akt T308 (p = 0.049) in the LN mets. HER2+ also had higher level of HER1 (p = 0.049), p-HER3 (p = 0.049), p-FGFR (p = 0.083), and p-4EBP1 (p = 0.049) in the LN mets compared to primary BCs. Higher levels of HER1 (p = 0.043) and p-MEK1/2 (p = 0.027) were observed in Lum B LN mets compared to p-IGFR (p = 0.041), p-Akt S473 (p = 0.088), p-S6 (p = 0.063) and p-4EBP1 (p = 0.097) in Lum A LN mets. Conclusions: In TNBC, preliminary results show that p-Akt is differentially upregulated in LN mets while HER1, p-HER3 and p-4EBP1 are overexpressed in HER2+ LN mets. Lum A LN mets showed higher levels of p-IGFR, p-Akt, p-S6 and p-4EBP1 vs Lum B LN mets which had higher levels of HER1 and p-MEK1/2. These data suggest different signaling pathways in BC LN mets compared to primary BCs. Analyses of 60 pts' matched primary BC/LN samples will be presented.
