Discovery of Next-Generation ADCs: Preclinical and Clinical Development of AVID100, an EGFR-Targeting ADC

Presentation Friday, April 12th at 11:35 AM ET, Harborview 1 & 2

AVID100 is highly potent and selectively cytotoxic against EGFR-expressing cancer cells, while sparing normal EGFR-positive keratinocytes
AVID100 was well-tolerated in a Phase 1 dose-escalation study in patients with advanced solid tumors of epithelial origin (any EGFR status)
Only modest skin toxicity observed, in line with preclinical findings
Phase 2 trial (AVID100-01; NCT03094169) ongoing to evaluate AVID100 efficacy, safety, and tolerability in patients with EGFR-overexpressing (IHC 3+) SCCHN and sqNSCLC
About AVID100 and the AVID100-01 Trial
AVID100 is a highly potent EGFR-targeting antibody-drug conjugate (ADC) that was engineered to achieve enhanced anti-tumor efficacy without a corresponding increase in toxicity against skin and other EGFR-expressing normal tissues. In preclinical studies, AVID100 demonstrated significant anti-cancer activity, including in EGFR-overexpressing tumor models that are resistant to marketed EGFR inhibitors. AVID100 is the only anti-EGFR ADC in clinical development that targets both wild-type and mutant forms of EGFR.

In a successfully completed Phase 1 study, AVID100 reported a recommended Phase 2 dose (RP2D) of 220 mg/m2 (~6mg/kg), which is expected to be in the therapeutically active range based on preclinical efficacy studies. Treatment was generally well-tolerated, with the majority of treatment-related adverse events in the Phase 1 trial at the RP2D being grade 1 or 2 in severity.

AVID100-01 (NCT03094169) is an open label, multicenter study to evaluate the efficacy, safety, and tolerability of AVID100 in patients with confirmed EGFR-overexpressing tumors (more than 50% of cells with EGFR 3+ or more than 75% of cells with EGFR 2+ staining by a validated immunohistochemistry assay).

On April 9, 2019 Foundation Medicine and Flatiron Health reported the publication of study results in the Journal of the American Medical Association validating that real-world clinico-genomic data obtained during the course of routine patient care can yield scientifically and clinically meaningful insights (Press release, Foundation Medicine, APR 9, 2019, View Source [SID1234535090]). These insights can serve as real-world evidence to advance research and discovery in oncology, and may also ultimately inform clinical guidelines. The continuously-updated, de-identified clinico-genomic database includes patient outcomes data processed from patients in Flatiron Health’s network of oncology clinics, linked with comprehensive genomic profiling (CGP) results from Foundation Medicine’s FoundationCORE database.

The findings demonstrate the feasibility of creating a de-identified clinico-genomic database (CGDB) and validate the potential of such real-world data for understanding and optimizing personalized cancer care, including, for example, biomarkers of response to immunotherapy treatment. The study linked clinical data from the electronic health records (EHRs) of 28,998 patients from 275 oncology practices in Flatiron Health’s network across the United States with genomic data from Foundation Medicine CGP testing. Among 4,064 patients with non-small cell lung cancer (NSCLC), exploratory analyses recapitulated previously described associations between clinical and genomic characteristics, between driver mutations and response to targeted therapy, and between tumor mutation burden (TMB) and response to immunotherapy.

"The publication of our validation study in a high-profile journal not only validates the ability of a real-world clinico-genomic database to yield scientifically and clinically-relevant findings, but also the potential for this novel approach to significantly impact our understanding of personalized medicine. This represents a major milestone in our mission to leverage regulatory-grade, real-world data to advance cancer care," stated Gaurav Singal, MD, chief data officer at Foundation Medicine. "As the dataset continues to grow, we expect it will advance therapeutics development, optimize clinical trial design and execution, and ultimately even support clinical decision making, enabling a more efficient way to evaluate new medicines and accelerate their availability for patients who need them."

In addition to demonstrating the scientific validity of the database for rigorous research, the study findings confirmed and extended several biomarker hypotheses in oncology. Corroborating recent clinical trial data, high TMB was shown to be associated with both longer duration on anti-PD-1/PD-L1 therapy and improved overall survival (OS) from treatment initiation. In addition, this retrospective real-world analysis re-demonstrated the importance of genomic biomarker-guided targeted treatment in NSCLC: among patients with genomic alterations known to drive tumor growth, treatment with agents targeted to these mutations was associated with prolonged survival. These findings may be extended in the future to identify additional factors associated with response to targeted therapies and immunotherapies.

"Our proof-of-principle study validated the importance of marrying tumor genomic data with clinical outcomes recorded during routine care, which represents a huge stream of data that is being generated and recorded every day, but has not yet been used meaningfully outside of patient care," said Vineeta Agarwala, MD, PhD, director of product management at Flatiron Health. "These data can inform treatment guidelines, clinical trial design, and precision drug development."

Since launching in November 2016, the CGDB now includes linked, de-identified data for more than 50,000 patients (over 6,000 with non-small cell lung cancer) and helps researchers and biopharmaceutical partners accelerate the development of targeted therapeutics and immunotherapies to treat cancer. The CGDB includes de-identified clinical data (demographic data, medication history, laboratory testing, and outcomes including survival) from Flatiron Health linked to genomic data (comprehensive genomic profiling of tumors, including genomic findings, variant annotations, and computational biomarkers such as tumor mutational burden [TMB], microsatellite instability [MSI], and loss of heterozygosity [LOH]) from Foundation Medicine across a variety of tumor types, allowing for a continuously updated, longitudinal view of a patient’s clinical, diagnostic and therapeutic journey.

"We are excited to be presenting our preclinical data supporting Cargocytes, a first-of-its-kind, cell-based platform technology for delivery of an Oncolytic Virus into metastatic tumors," said Remo Moomiaie-Qajar, M.D., president and CEO of Cytonus. "Our technology unleashes the promise of using Oncolytic Viruses to treat solid tumors by addressing a number of critical problems they inherently have, mainly homing the viruses to specific tissue without the immune system destroying it and then delivering those viruses into tumor cells. In addition, we are proud of our growing immune-oncology work with our Cargocytes and look forward to sharing our data at this year’s ASGCT (Free ASGCT Whitepaper) meeting."

Cargocytes are engineered allogenic cell lines that can carry a variety of payloads like small molecule compounds, gene editing therapies, therapeutic RNAs, and powerful biologics such as immune modulating cytokines, antibodies and oncolytic viruses.
