Science Never Stops – Neither Do We!

Support seamless transition every step of the way

With a robust global infrastructure, financial resilience, and years of CRISPR expertise, we ensure your science never skips a beat. Ready for an Upgrade? Our dedicated Transition Support Team is here to assist every step of the way!

INDEdit gRNA: Enabling a Seamless Transition from IND-enabling Studies to Clinical Trials

INDEdit gRNA is our upgraded guide RNA offering designed to simplify the path to IND approval and clinical application. Developed based on GenScript’s extensive experience supporting successful IND applications, this service ensures alignment with FDA and EMA recommendations for preclinical/IND-enabling studies while offering a cost-effective solution with only the essential QC tests necessary for IND approval.

Unlike other vendors, INDEdit gRNA is manufactured entirely within our cGMP facility, eliminating the need for costly and time-consuming comparability studies when moving from preclinical to full cGMP production. This is critical, as both the FDA and EMA require that first-in-human clinical drug products remain representative of those used in preclinical studies. By keeping manufacturing consistent, we help you avoid regulatory hurdles and accelerate your IND submission.

FAQs

  • Rx-360 is the International Pharmaceutical Supply Chain Consortium with the mission to protect patient safety by sharing information and developing processes related to the integrity of the healthcare supply chain and the quality of its materials. The nonprofit organization launched the Rx-360 Joint Audit Program® in 2013. Pharmaceutical clients can request Rx-360 to sponsor audits of suppliers and license the audit report after audit completion. GenScript’s Zhenjiang site audit JA-3136 was conducted from 25-28 March 2025 and the audit report is available for licensing.

  • Why license this report
    • Save valuable time and internal resources by leveraging the Rx-360 audit report instead of conducting your own audit.
    • Reduce the complexity of vendor qualification audits and focus on your business objectives.
    • Rx-360 as central liaison manages on your behalf the audit process including the CAPA follow up and protects confidentiality of all the parties.
  • Does my project need cGMP materials?

    Recent FDA guidelines recommend GMP reagents be used prior to IND enabling studies and clinical trials of novel cell and gene engineering, including for master cell bank generation. To prevent potential regulatory issues, researchers will need to source phase-appropriate GMP reagents and submit detailed production documentation with their IND filing.

  • Is there a waitlist to start cGMP gRNA production with GenScript?

    Unlike other suppliers, GenScript has the capacity to begin your cGMP gRNA synthesis project without delay. Reach out to crispr@genscript.com to discuss your project timeline with us.
