Problems solved by technology

Despite impressive advances in our medical devices for molecularly-targeted anticancer therapies, the extreme molecular complexity underlying cancer cell behavior has left us with significant inadequacies in our ability to predict which patients will benefit from any particular therapy
Lack of effective means of predicting patient response directly leads to ineffective treatment cycles, with substantial opportunity costs for patients and significant economic costs for patients and healthcare payers

Embodiment approach

[0126] (1) A method of treating cancer in a subject in need thereof, said method comprising administering to said subject a therapeutic molecule selected from a library of therapeutic molecules; wherein said therapeutic molecule is selected by a method comprising the steps of : modifying cancer cells from said subject to knock down or knock out the function of a plurality of genes, each gene in said plurality of genes encoding a protein target of a therapeutic molecule in said therapeutic molecule library, wherein if said The therapeutic molecule is selected if the therapeutic molecule knocks down or knocks down the function of a gene encoding a protein target of the selected therapeutic molecule impairs cancer cell viability.

[0127] (2) The method according to said embodiment 1, wherein said library of therapeutic molecules comprises at least 1, at least 2, at least 3, at least 4, at least 5, at least 10 or At least 20 healing agents.

[0128] (3) The method according to e...

Embodiment 1

[0569] Example 1: Genetic Pharmacopoeia

[0570] A drug library comprising the molecularly targeted tumor drugs of Table 2B was generated. The drug library is regularly updated to include additional tumor-targeting drugs as they are identified. A genetic pharmacopoeia was generated to represent the genetic targets of the drug library (Table 5B).

[0571] Libraries of gene regulators containing guide RNA (gRNA) sequences associated with each gene target were designed. As shown in Table 6A, five potential gRNA sequences were designed for each tumor drug target to generate gRNA sequences with SEQ ID NOS: 1-1525. A library of gene regulators is constructed to comprise at least one gRNA sequence selected from SEQ ID NOS: 1-1525. Libraries were constructed using viral delivery methods (adenovirus for Cas nuclease delivery and lentivirus for gRNA delivery) in a format compatible with use in primary cancer cells.

Embodiment 2

[0572] Example 2: Cancer Functional Susceptibility Analysis

[0573] A method is performed to determine the functional susceptibility of cancer cells in a patient to one or more interferors that mimic the effects of the tumor-targeting drugs identified in Example 1. Libraries comprising at least one gRNA sequence selected from SEQ ID NOS: 1-1525 and associated gene editing agent(s) (e.g., RNA-guided nucleases) are delivered to patient-derived primary cancer cells , in order to genetically modify cancer cells. Delivery of Cas nuclease and gRNA via lentivirus. In this example, genetic modification was performed by gene editing using a CRISPR-based approach. The modified cancer cells proliferate in vivo, however, the method can be used in an in vitro environment that mimics the in vivo environment. The effect of each gene edit was assessed by screening the modified cancer cells in pools or arrays. Next-generation sequencing techniques are performed to determine the effect of ...

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 865,047, filed June 21, 2019, which is hereby incorporated by reference in its entirety. [0003] sequence listing [0004] This application contains a Sequence Listing, which has been filed electronically in ASCII format and is hereby incorporated by reference in its entirety. Said ASCII copy, created on June 18, 2020, is named 56322-701_601_SL.txt and is 732,058 bytes long. Background technique [0005] Human cancers are very heterogeneous, differing at the DNA sequence, epigenomic landscape, RNA expression, and protein levels, resulting in enormous combinatorial complexity in cellular behavior. Despite impressive advances in our medical devices for molecularly-targeted anticancer therapies, the extreme molecular complexity underlying cancer cell behavior has left us with significant inadequacies in our ability to predict which patients will benefit f...
