The Standard for Exchange of Nonclinical Data (SEND) is an implementation of the CDISC Standard Data Tabulation Model (SDTM) for nonclinical studies, which specifies a way to present nonclinical data in a consistent format. These types of studies are related to animal testing conducted during drug development. Raw data of toxicology animal studies started after December 18, 2016 to support submission of new drugs to the US Food and Drug Administration will be submitted to the agency using SEND.

Having a common model to which the industry can conform enables benefits such as the ability for vendors to develop tools, for inter-organizational data exchange that is consistent in format regardless of the parties involved, and so on.

A SEND package consists of a few parts, but the main focus is on individual endpoint data. Endpoints typically map to domains (essentially, datasets), with a number of variables (a.k.a., columns or fields).

Implementation

The SEND Implementation Guide (SENDIG) is a document that provides implementers with specifications for implementing SEND, including how to model various nonclinical endpoints, rules to doing so, and examples with sample data. This document is available on the CDISC SEND website. [1]

Supplementing the guide is the SEND Implementation Wiki [2] hosted by PhUSE designed to assist with the implementation process and filling in some of the gaps, most notably containing:

Companion to the wiki is the SEND Implementation Forum, [3] which allows implementers to ask questions and get responses from SEND experts. New implementers are encouraged to ask questions here.

History

The work on this standard began in July 2002—subsequently, a U.S. Food and Drug Administration pilot project was initiated in July 2003 through a Cooperative Research and Development Agreement (CRADA). Feedback from this pilot and continuous efforts to more closely align this implementation with the SDTM for human clinical trials led to development of SEND 2.3, but without widespread adoption.

In 2006, with renewed FDA interest, the industry met to revive SEND and work on a version that, with FDA backing, would cover regulatory submission as well as operational data transfer needs. By 2007, an FDA pilot was announced, during which time the SEND team worked on the SENDIG (implementation guide).

SENDIG 3.0 was released to production in July 2011. This was soon followed by the FDA's statement of preference for SEND datasets.

In December 2014, the FDA CDER and CBER divisions released guidance for industry enforcing the usage of SEND as part of Investigational New Drug (IND) and Biologic License Application (BLA) submission to the US Food and Drug Administration. All studies started after December 15, 2016 supporting IND and BLA submissions will need to be compliant with SEND. The Pharmaceuticals and Medical Devices Agency in Japan will enforce its use in the future, most probably in 2020. The European Medicines Agency also expressed interest and is recommending the use of SEND.

SENDIG 3.1 was released in June 2016, extending the format with new data domains. SENDIG-DART 1.1 was released in December 2017. SENDIG-DART is a standard which extends the SENDIG 3.1 standard for use with Segment II Development and Reproductive Toxicology Studies. Consider the SENDIG and the PhUSE SEND Implementation Wiki pages for additional related information.

In the experimental (non-clinical) research arena, good laboratory practice or GLP is a quality system of management controls for research laboratories and organizations to ensure the uniformity, consistency, reliability, reproducibility, quality, and integrity of products in development for human or animal health through non-clinical safety tests; from physio-chemical properties through acute to chronic toxicity tests.

The Clinical Data Interchange Standards Consortium (CDISC) is a standards developing organization (SDO) dealing with medical research data linked with healthcare, to "enable information system interoperability to improve medical research and related areas of healthcare". The standards support medical research from protocol through analysis and reporting of results and have been shown to decrease resources needed by 60% overall and 70–90% in the start-up stages when they are implemented at the beginning of the research process.

The electronic common technical document (eCTD) is an interface and international specification for the pharmaceutical industry to agency transfer of regulatory information. The specification is based on the Common Technical Document (CTD) format and was developed by the International Council for Harmonisation (ICH) Multidisciplinary Group 2 Expert Working Group.

Clinical research is a branch of healthcare science that determines the safety and effectiveness (efficacy) of medications, devices, diagnostic products and treatment regimens intended for human use. These may be used for prevention, treatment, diagnosis or for relieving symptoms of a disease. Clinical research is different from clinical practice. In clinical practice established treatments are used, while in clinical research evidence is collected to establish a treatment.

Structured Product Labeling (SPL) is a Health Level Seven International (HL7) standard which defines the content of human prescription drug labeling in an XML format. The "drug labeling" includes all published material accompanying a drug, such as the Prescribing Information which contains a great deal of detailed information about the drug. As of Release 4 of the SPL standard, 22,000 FDA informational product inserts have been encoded according to the standard.

Drug Master File or DMF is a document prepared by a pharmaceutical manufacturer and submitted solely at its discretion to the appropriate regulatory authority in the intended drug market. There is no regulatory requirement to file a DMF. However, the document provides the regulatory authority with confidential, detailed information about facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of one or more human drugs. Typically, a drug master file is filed when two or more firms work in partnership on developing or manufacturing a drug product. The DMF filing allows a firm to protect its intellectual property from its partner while complying with regulatory requirements for disclosure of processing details.

Leronlimab is a humanized monoclonal antibody targeted against the CCR5 receptor found on T lymphocytes of the human immune system.

Janus clinical trial data repository is a clinical trial data repository standard as sanctioned by the U.S. Food and Drug Administration (FDA). It was named for the Roman god Janus (mythology), who had two faces, one that could see in the past and one that could see in the future. The analogy is that the Janus data repository would enable the FDA and the pharmaceutical industry to both look retrospectively into past clinical trials, and also relative to one or more current clinical trials.

Genta (company)

Genta Incorporated was a biopharmaceutical company started in La Jolla, California, which discovered and developed innovative drugs for the treatment of patients with cancer. Founded in 1989 by a highly skilled entrepreneur, the company focused on a novel technology known as antisense, which targets gene products that are associated with the onset and progression of serious diseases. At that time, only Ionis Pharmaceuticals, Inc. was conducting significant research with this technology. Antisense is a short span of oligonucleotides – modified DNA structures ranging from about 12-24 bases that selectively bind to specific RNA. The intent is to block expression of an aberrant protein that contributes to the disease of interest. Genta in-licensed three different antisense molecules that blocked Bcl-2, a fibroblast growth factor (FGF), and the gene c-myb, respectively.

Regulated Product Submission (RPS) is a Health Level Seven (HL7) standard designed to facilitate the processing and review of regulated product information. RPS is being developed in response to performance goals that the U.S. Food and Drug Administration (FDA) is to achieve by 2012, as outlined in the Prescription Drug User Fee Act (PDUFA). In addition to the U.S., regulatory agencies from Europe, Canada, and Japan are at varying levels of interest and participation. Currently, the second release of RPS is in development.

The BioCompute Object (BCO) Project is a community-driven initiative to build a framework for standardizing and sharing computations and analyses generated from High-throughput sequencing. The project has since been standardized as IEEE 2791-2020, and the project files are maintained in an open source repository. The July 22nd, 2020 edition of the Federal Register announced that the FDA now supports the use of BioCompute in regulatory submissions, and the inclusion of the standard in the Data Standards Catalog for the submission of HTS data in NDAs, ANDAs, BLAs, and INDs to CBER, CDER, and CFSAN.

Originally started as a collaborative contract between the George Washington University and the Food and Drug Administration, the project has grown to include over 20 universities, biotechnology companies, public-private partnerships and pharmaceutical companies including Seven Bridges and Harvard Medical School. The BCO aims to ease the exchange of HTS workflows between various organizations, such as the FDA, pharmaceutical companies, contract research organizations, bioinformatic platform providers, and academic researchers. Due to the sensitive nature of regulatory filings, few direct references to material can be published. However, the project is currently funded to train FDA Reviewers and administrators to read and interpret BCOs, and currently has 4 publications either submitted or nearly submitted.
