Intelligent Protocol Hub

Intelligent Protocol Hub is an AI-powered clinical trial protocol management platform that serves as an end-to-end workspace for clinical operations, regulatory, and development teams in pharma and biotech. It combines intelligent drafting (with AI-assisted authoring and content suggestions), real-time multi-user collaboration, built-in risk detection (to identify potential issues early and reduce protocol amendments), version control, electronic signatures, and centralized document/template management - all in one secure, compliant environment. Built on a foundation of over 12,000+ protocols and 70 billion+ clinical data points, the platform accelerates protocol development while preserving scientific rigor and regulatory alignment (supporting ICH E6 GCP standards and similar guidelines). Teams can start from standardized templates (e.g., NIH official), track progress across statuses (draft to approved), manage approvals efficiently, and maintain a single source of truth for all protocol-related documents. Key benefits include faster time-to-protocol-finalization, fewer delays, improved cross-functional visibility, and reduced manual rework - helping small, mid, and large pharma and biotech organizations streamline upstream clinical trial protocol development without compromising quality or compliance.

AQ Trials

AQ Platform is clinical research software for NHS trusts, CTUs and academic sites, CROs, sponsors and site networks. Its modules, CTMS, eTMF, eISF, Pharmacy, eSource, Labs, QMS, CAPA and Digital DoA, are each priced and deployed independently, and when used together they share one governed, audit-trailed record. That replaces separate binders, spreadsheets and shared drives, removes duplicate entry and pre-visit reconciliation, and keeps the record inspection-ready at any point in the study. A visit booked in the CTMS builds the sample list in AQ Labs, delegation and training decide who can act, a deviation raises a CAPA, and certificates and signed reports file to the site file. Pharmacy covers IMP accountability end to end, with the electronic pharmacy site file (ePSF) built in. Connected Intelligence reviews the record and flags missing signatures, expiring documents, overdue training and open actions for the responsible person to review, and AQ Assist works inside the platform. AQ meets the NHS DSPT standard (Standards Met 2026), holds Cyber Essentials, and supports 21 CFR Part 11 electronic signatures and ICH E6(R3). Every engagement starts with a free first consultation.
