• The NHLBI Catalyze program provides a comprehensive suite of support and services to facilitate the translation of basic scientific discoveries into viable therapeutics, devices, and diagnostics ready for human testing.
• The program has two main goals:
  • To drive development of new potential heart, lung, blood, and sleep (HLBS)-related therapies and cures — including drugs, devices, diagnostics, and biologics — by supporting early product definition studies and safety testing
  • To support development of novel, enabling platform technologies that catalyze next-generation predictive, diagnostic, and therapeutic products. These products will specifically address HLBS-related disorders and diseases.
  • To train a diverse, globally competitive biomedical workforce that is well-versed in scientific research, technology development, and entrepreneurship
• Currently, the Catalyze program supports five funding opportunities, and their funding mechanisms differ in their budget limits, cost sharing expectations, application materials, and project period.
• This funding supports three overall categories of product development and preclinical research:
  • Therapeutics (small molecules and biologics)
  • Devices, diagnostics, and research tools
  • Enabling technologies and transformative platforms

Catalyze Funding Opportunities

Currently, there are five funding opportunities: two that target therapeutics (dependent on early or late entry stage of development), two that target devices, diagnostics, and tools (dependent on early or late entry stage of development), and one that targets enabling technologies and transformative platforms. The five funding opportunities are summarized in the table below.

Phased Awards (R61/R33) and Direct to R33

Catalyze funding mechanism requirements (budget limits, cost sharing, Accelerator Partnerships, etc.) differ according to the type of technology under development, the stage of development, and the duration of the project. For therapeutic and device/diagnostic/tool development, both phased (R61/R33) and R33 awards are available. Researchers with projects that are earlier in development may apply for phased awards, while those with more advanced projects may apply directly for an R33 opportunity. In a phased award, transition from the R61 phase to the R33 phase is based on successful completion of the R61 phase and meeting additional R33 requirements.

This table summarizes the differences between the funding mechanisms:

Intellectual Property (IP) or Regulatory Strategy Requirements

• Applicants are required to submit their IP and regulatory strategies in their applications. Projects that are appropriate for these FOAs must be at the stage of development where IP and regulatory strategies are being considered. For phased awards, continued development of IP and regulatory strategies will be required and considered for a transition from the R61 phase to the R33 phase of the award.
• While IP and regulatory strategy are not required for the Enabling Technologies and Transformative Platforms funding opportunity (RFA-HL-23-010), funded awardees will be expected to develop IP and regulatory strategy as the technology develops.

Accelerator Partners

Accelerator Partner Definition

• Accelerator Partners are commercialization experts working as development partners with innovators whose projects are funded through the Catalyze program. Accelerator Partners help innovator-researchers achieve the necessary multidisciplinary approach for developing technologies. Accelerator Partners provide skills development and mentoring to enable innovator-researchers to assess the medical and commercial potential of their projects. They also help advance the proposed projects to a stage suitable to continue product development in the private sector or to apply for support through the NHLBI Catalyze Preclinical or other translational programs.
• Accelerator Partners do this by connecting innovator-researchers with people such as:
  • experienced entrepreneurs and scientists, including those who can facilitate interactions with businesses, industries, sources of private capital, and research-performing institutions,
  • potential licensing and commercialization partners who can offer advice soon after the researcher gets an award,
  • ecosystem partners, such as those from biotechnology or pharmaceutical companies, who are knowledgeable about the process for developing therapeutics, devices, and diagnostics,
  • experts such as clinicians and biostatisticians who are familiar with how the desired product should look to meet vested shared interests,
  • potential partners who have complementary development expertise and resources for successful project development.

Accelerator Partners Expectations

• Accelerator partners are encouraged to provide access to expertise and mentoring related to: product development stages, business development and commercialization strategy, market analysis, preparation of regulatory submissions, intellectual property protection, and reimbursement strategy. Awardees are highly encouraged to use Accelerator Partners for this kind of career development, as these experts can facilitate exposure to the myriad processes required to translate discoveries into therapies.
• Applicants are expected to consider how they will identify and foster relationships with Accelerator Partners. At least one Accelerator Partner is required for the R33 portion of the phased awards and the R33 only awards. An Accelerator Partner is not required for RFA-HL-23-010.
• For phased awards, awardees will be expected to search for an Accelerator Partner early in the R61 phase. For phased awards, proof of an Accelerator partner is not required at the time of application; however, evidence that an Accelerator Partner has been identified must be provided to NIH in the form of a letter of support prior to the meeting of the NHLBI committee that will decide whether an awardee will transition from the R61 to the R33 award. Transition from R61 to R33 is contingent on procurement of an Accelerator.

Milestones

Milestone Definition

• Milestones are an event or moment in time in a project that indicates progress toward a Specific Aim has been made or that a Specific Aim has been completed. The project Specific Aims and milestones should be laid out as a timeline or GANTT chart as a part of the application. Specific Aims or a list of activities planned for each year are not considered milestones because they do not provide decision-making goals. Applicants are expected to propose activities and milestones, with an associated timeline, to be completed during the proposed duration of award. Successful awardees will develop specific, measurable, achievable, relevant, and time-bound Specific Aims for their project. Each Specific Aim should have at least one milestone associated with it.

Milestone Requirements

• Milestones will be peer reviewed as well as programmatically reviewed and if needed will be negotiated with the awardee before they are included in the terms of the award. NHLBI staff will monitor program progress against proposed milestones through quarterly meetings and make non-competing award decisions annually based on achieving milestones. NHLBI emphasizes the importance of the robustness and reproducibility of experimental results in evaluating progress.
• Milestones are required for all RFAs (RFA-HL-23-010, 011, 012, 013, and 014).
• Phased awards (RFA-HL-23-011 and RFA-HL-23-013). To be responsive to this FOA, applicants must meet the entry criteria to be eligible for the award and propose two separate sets of clear, quantifiable milestones with timelines (one set each for the R61 and R33 phases) to be completed sequentially within a three-year period, but with no more than two years in either stage.
• Milestones for the R61 and R33 activities must be submitted at the time of application and will be reviewed simultaneously; however, receipt of funding for the R33 component of phased awards is contingent on achieving pre-specified milestones during the R61 component. Completion of milestones will ensure sufficient progress during the R61 phase to provide the feasibility and scientific rationale to conduct the product definition activities proposed in the R33.
• Non-phased R33 awards (RFA-HL-23-010, RFA-HL-23-012 and RFA-HL-23-014). To be considered responsive to the FOA, applicants must meet the entry criteria to be eligible for the award and propose milestones to be completed during the duration of award. These milestones will ensure that projects are sufficiently progressing to be in a position to for further development, including entering into preclinical programs following completion of the award.
• Milestones must be identified in the application and may be negotiated, pre-award, by the NHLBI team based on comments from the peer review panel. NHLBI emphasizes the importance of the robustness and reproducibility of experimental results in evaluating progress. For the phased awards, investigators must exhibit successful completion of milestones for consideration of transition to the R33 phase.

Project Management

• Each project is expected to use a robust, milestone-driven project management processes that make it possible to assess progress on a continuous basis, relative to established milestones. Applicants should describe their project management strategies and name the individual(s) who will be responsible for implementing them. For more information about developing project management strategies prior to application submission, please contact the NHLBI Catalyze team at catalyze_info@rti.org.

To apply, an applicant can complete an Expression of Interest (EOI) form, which is subsequently reviewed by the NHLBI. If selected, applicants are invited to complete a full online application through a secure Catalyze website. Full applications have an open period of ~4 weeks for applicants to submit their requested services.

Applications are completed through an online portal. Applicants are encouraged to utilize the PDF / Word copy of the Catalyze Application to gather information needed for submission. The applicant may draft responses on the Word version and use it as a template to copy/paste into the Catalyze website. The application can take between 4-6 hours to complete. After the submission period ends, the Catalyze Coordinating Center (RTI) may contact the applicant by email if there are questions about the application. Applicants will be notified of the final decision by email within 6 months.

The application should demonstrate an understanding of the necessary steps to advance the technology from its current stage to FDA clearance, as well as the steps to advance from FDA clearance to commercialization. If the goal is market approval, applicants may request several services but in general, the program does not support projects above $1,000,000/year. NHLBI may work with applicants to adjust which services can be supported by Catalyze. Other funding sources may be required.

While the Catalyze program does not enforce a fixed budget cap on applications, in general the program does not support projects above $1,000,000/year, however this can vary depending on product type (e.g., biologics, cell therapy, gene therapy).

For more information about applying for preclinical services, please visit the Preclinical Services page.

Applicants can request a range of preclinical services including preclinical efficacy studies, dose range finding studies (i.e., early toxicology studies), GLP toxicology studies, or in vivo animal studies for devices.

Applicants can also request services for manufacturing.

Please note that the Catalyze Preclinical Services Program will not support any GLP/GMP requests before a pre-IND meeting. The applicant may request regulatory support for a pre-IND meeting.

Clinical trials are not supported by Catalyze Preclinical Services.

Within 4-6 weeks of submitting an EOI, applicants will receive notification of rejection or an invitation to submit a full application.

Future submission dates for EOIs are not yet determined but will be announced and posted on the website when finalized. A downloadable version of the EOI and full application are accessible on the Preclinical Services Program page. NHLBI anticipates 1-2 submission cycles for fiscal years 2023 and 2024.

Funds will not be awarded to the applicant.

Accurate CRO/CMO quotes must be provided with the preclinical application. If accurate CRO/CMO quotes are not provided, the application will be noted as "unresponsive" and will not go out for peer review.

The Catalyze Coordinating Center (RTI) will manage the services and work with the investigators to ensure that tasks are being completed correctly at the CROs/CMOs. The Catalyze Coordinating Center (RTI) will select CROs/CMOs that will provide preclinical services.

Additional commercialization milestones will be required of the investigator.

While not a requirement, applicants are encouraged to have an accelerator partner. NHLBI expects applicants to pursue fundraising to increase the likelihood that the technologies will advance to the marketplace.

Small businesses may seek support from the SBIR Program NHLBI Small Business Program | NHLBI, NIH.

Either academic PIs or accelerator partners may apply, but the applicant must ensure the support of a specific suitable development team to support the technology.

Contract Research Organization (CRO) / Contract Manufacturing Organization (CMO) Quotes

• Applicants are expected to provide cost estimates for services requested from the Catalyze Program as part of their full application. It is recommended that quotes are requested from CROs/CMOs shortly after EOI submission.
• Following selection, the Catalyze Coordinating Center (RTI) will verify cost estimates and qualify the CRO/CMOs prior to the initiation of the studies. The Catalyze Coordinating Center (RTI) may obtain additional bids for comparison to identify the most appropriate vendor. These bids will be obtained from vendors in compliance with federal procurement regulations.
• If an applicant has been accepted into the program and previously worked with a CRO/CMO, it may be more cost/time efficient to continue working with that vendor although other vendor estimates may be obtained by the Catalyze Coordinating Center (RTI) for comparison.
• The Catalyze Coordinating Center (RTI) will perform a qualification for all vendors to ensure that the vendor meets the appropriate requirements and has experience providing reports and documentation sufficient for regulatory submission.
• CROs/CMOs located outside of the US will need to comply with U.S. State Department regulations as well as NIH policies. Please note, the use of international vendors will require additional clearance from the State Department and may delay the start of Catalyze services.
• Services provided by CROs can range from preclinical efficacy studies, non-GLP dose range finding studies, GLP toxicology studies, or in vivo animal studies for devices. Please note that the Catalyze Preclinical Services Program will not support any GLP/GMP requests before a meeting with FDA. The applicant may request regulatory support for a pre-IND/pre-Sub meeting.
• The Catalyze Coordinating Center (RTI) has expertise in toxicology, manufacturing, and regulatory strategy/regulatory submissions and will share Request for Proposal (RFP) templates that investigators can use to request quotes from CROs and CMOs.
• Applicants are welcome to contact NHLBI_catalyze@mail.nih.gov to request assistance identifying potential CROs or CMOs.
• If a technology already has a non-exclusive license executed with a CRO, please email NHLBI_catalyze@mail.nih.gov to initiate a discussion.
