AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice of availability.

SUMMARY:

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Nonclinical Testing of Individualized Antisense Oligonucleotide Drug Products for Severely Debilitating or Life-Threatening Diseases.” FDA is publishing this draft guidance to help sponsor-investigators (hereafter referred to as sponsors) with developing the nonclinical information that FDA recommends to support an investigational new drug application (IND) for certain individualized antisense oligonucleotide (ASO) drug products. ASO drug products that are the focus of this draft guidance are those being developed to treat rapidly progressing, severely debilitating or life-threatening (SDLT) disease attributable to a unique genetic variant or variants that may be amenable to RNA-directed treatment.

DATES:

Submit either electronic or written comments on the draft guidance by June 28, 2021 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.

ADDRESSES:

You may submit comments on any guidance at any time as follows:

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Nonclinical Testing of Individualized Antisense Oligonucleotide Drug Products for Severely Debilitating or Life-Threatening Diseases.” FDA is publishing this draft guidance, that, when finalized, will help sponsors with developing the nonclinical information that FDA recommends to support an IND for certain individualized ASO drug products. ASO drug products that are the focus of this draft guidance are those being developed to treat a rapidly progressing, SDLT disease attributable Start Printed Page 22214to a unique genetic variant or variants that may be amenable to RNA-directed treatment.

The draft guidance addresses the nonclinical information that FDA recommends to support an IND for the development of an antisense oligonucleotide from a well-characterized chemical class, for which there is substantial nonclinical information and clinical experience that is publicly available or to which the sponsor has a right of reference. The draft guidance discusses the importance of sponsors providing convincing in vitro and/or in vivo proof of concept data as part of any such IND submission. The draft guidance describes recommended nonclinical safety studies that should be submitted with such IND submissions, the duration and timing of general toxicity studies, first-in-human dose selection, and dose escalation, each within the context stipulated above. Finally, the draft guidance describes certain factors, present in the context of an IND for an individualized investigational antisense oligonucleotide developed to treat a rapidly progressing SDLT disease, that support differences in the nonclinical safety package recommended in this context from that generally recommended for non-SDLT diseases, for modalities other than antisense oligonucleotides, and for use in larger patient populations.

The draft guidance is intended to help sponsors of such development programs, who may be relatively unfamiliar with FDA regulations, processes, and practices, seek feedback from FDA on their development programs and make regulatory submissions related to these development programs. The draft guidance is expected to facilitate the preparation of adequate pre-IND and IND submissions for review by the Agency that will enable prompt initiation of the clinical trial.

This draft guidance represents the second in a series of guidances FDA intends to publish to advise and help sponsors developing individualized ASO drug products for individuals who have SDLT diseases or conditions and no approved products available to them to treat their disease.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on “Nonclinical Testing of Individualized Antisense Oligonucleotide Drug Products for Severely Debilitating or Life-Threatening Diseases.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

II. Paperwork Reduction Act of 1995

FDA tentatively concludes that this draft guidance contains no collection of information. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not required.

However, this draft guidance refers to previously approved FDA collections of information. These collections of information are subject to review by OMB under the PRA.

  • The following collections of information in 21 CFR part 312 (IND regulations) have been approved under OMB control number 0910-0014: (1) Submissions of IND applications, amendments, safety reports, and investigator brochures and (2) requests for pre-IND meetings.
  • The collections of information in 21 CFR parts 50 and 56 for obtaining informed consent for prospective patients have been approved under OMB control number 0910-0130.
  • The collections of information for paper submissions of Form FDA 3500A (Mandatory Reporting) have been approved under OMB control number 0910-0291.
  • The collections of information in the final guidance entitled “Formal Meetings Between the FDA and Sponsors or Applicants” have been approved under OMB control number 0910-0429.
  • The collections of information relating to electronic submissions of Form FDA 3500 used for voluntary reporting (not mandated by law or regulation) by healthcare professionals, including safety reporting submissions relating to bioavailability and bioequivalence studies under 21 CFR 320.31(d)(3), have been approved under OMB control number 0910-0645.
