Cambridge Healthtech Institute’s 5th Annual
Target Identification & Phenotypic Screening
Leveraging Functional Genomics, Cellular Assays and Computational Tools
June 19-20, 2019
Identifying novel, druggable targets for therapeutic intervention or probing existing drug targets for new therapeutic indications is a crucial part of the early discovery process. Target-based and phenotypic screening are most commonly used approaches
for finding and validating drug targets. How well do these approaches work? What new technologies are being developed? How do you evaluate and decide on which technique or assay to use? Are there ways to screen “hard-to-find” targets?
Cambridge Healthtech Institute’s conference on Target Identification & Phenotypic Screening brings together experts from pharma/biotech and academia to address some of these questions and more. It provides a unique networking
opportunity for people to interact, share ideas and discuss new strategies and technologies helping target discovery.

John Doench, PhD,
Associate Director, Genetic Perturbation Platform, Broad Institute of Harvard and MIT
CRISPR screens have become the method of choice for large-scale assessment of gene function, but implementation in complex model systems remains a significant challenge. Here I will present the optimization of mouse models to discover modulators of
tumor immunotherapy. Combinatorial screens present similar challenges and will also be discussed.
8:45 Large Scale Proteomics Approaches to Accelerate Degrader Development
Donovan, PhD, Scientist, Laboratory of Dr. Eric Fischer, Cancer Biology, Dana-Farber Cancer Institute/Harvard Medical School
Targeted protein degradation utilizing the Ubiquitin Proteasome System has emerged as a promising strategy for drug discovery. Small molecules like molecular glues and PROTACs can hijack E3 ligases to induce ubiquitin-mediated degradation of neo-substrates.
To aid discovery and development of novel degraders, effective tools for proteome-wide monitoring of degrader targets and off-targets are necessary. We will present strategies for target identification and mode-of-action deconvolution centered
on multiplexed shotgun proteomics.
9:15 From Co-Culture with Non-Cancerous Cells to the Production of Macrotumors: New Horizons for the Targeted Development of Anti-Cancer Therapy
Sophie Lelievre, DVM, PhD, LLM, Professor, Cancer Pharmacology, Purdue University College of Veterinary Medicine
In vitro production of tumors is paramount to improve target identification and drug testing compared to classical monolayer culture. However, the microenvironment ought to be considered to best recapitulate conditions
promoting tumor progression and resistance to treatment. Tumor size also matters to reproduce intermittent oxygenation and the proper ratio of tumor and stromal cells. I will present how 3D cell culture might be used for the identification of
targets to fight anti-cancer drug resistance.
9:45 ZeGenesis: CRISPR/Cas9 Innovative Zebrafish Platforms for Disease Modelling and Target Validation
