TransPharm Preclinical Solutions

TransPharm Preclinical Solutions, Inc. is a small infectious disease specialist in Jackson, Michigan. It was founded in 2008 by Daniel Ross and remains privately and family held.^[S2] Its scope is narrow and clearly stated: rodent efficacy models of infection, supported by in vitro microbiology, run in its own vivarium.^[S3][S4][S5] Two points shape how a sponsor should read it. The facility is biosafety level 2, not level 3, so agents requiring higher containment are out of scope.^[S3] And the company publishes its animal welfare credentials in unusual detail, including accreditation and assurance numbers.^[S7] This profile summarizes the services, facility, stated compliance information, and company facts most relevant to US sponsors.

Services relevant to US drug developers

In vivo infection models and in vitro microbiology

The company runs efficacy models of infection in mice and rats, with pharmacokinetic blood sampling available alongside the efficacy readouts.^[S4] In vitro microbiology, including minimum inhibitory concentration determination, supports compound triage before animal work.^[S5] Only mice and rats are used; no larger species are offered, which keeps the model set within what a BSL-2 facility can support.

Pathogen coverage

The homepage cites more than 50 pathogens,^[S1] while the pathogen listing page names 34 individually.^[S6] Both figures are reproduced here as published; the gap may reflect strains held but not listed, or a figure that has not been updated. Sponsors should confirm that the specific organism and strain for their program is available, and that it can be handled at biosafety level 2.

The facility

The vivarium is described as AAALAC accredited and operating at biosafety level 2, with nine bioBubble isolation cabins.^[S3] Isolation cabins matter in infection work because they allow several studies with different organisms to run at once without cross-contamination, which is often the practical constraint on scheduling at a small site. Unlike consortium or brokerage models, TransPharm houses the animals itself, so the accreditation and assurance below apply to the facility that will actually run the study.

Quality, compliance, and animal welfare (as stated by the company)

Accreditation and assurance numbers are published. The company states AAALAC accreditation held since October 2009 under file number 001301, and a PHS Animal Welfare Assurance with the Office of Laboratory Animal Welfare held since June 2014 under assurance number A4707-01, together with the composition of its Institutional Animal Care and Use Committee.^[S7] Publishing the file and assurance numbers lets a sponsor check the status against the issuing bodies' own records rather than taking the claim on trust, which is more than most sites in this list provide. AAALAC International accreditation is a voluntary evaluation of an institution's animal care and use program, re-evaluated every three years,^[R3] and USDA registration and an OLAW Animal Welfare Assurance relate to the Animal Welfare Act and the PHS Policy respectively;^[R4][R5] none of these establishes GLP compliance, which applies to individual studies.^[R2] FDA does not approve or certify laboratories; registration with FDA does not denote approval.^[R6] This profile does not evaluate the company's animal care program; the statements above are the company's own.

GLP is not claimed. No GLP statement was found on the pages reviewed, and no USDA registration statement appears for the facility itself; USDA is mentioned only in the founder's prior career description.^[S2][S7] A facility working only with mice and rats may fall outside Animal Welfare Act registration requirements, but that is a determination for the company and the agency rather than an inference to be drawn here. Sponsors needing a GLP study should confirm scope and regulation directly.^[R2]
