NINDS established the Early Phase Pain Investigation Clinical Network (EPPIC-Net) as a part of the NIH HEAL (Helping to End Addiction Long-term) Initiative. EPPIC-Net’s mission is to accelerate and enhance clinical testing of novel, non-addictive pharmacologic and non-pharmacologic therapeutic “assets”, including new and repurposed small molecules, biologics, natural products, and devices, targeted to pain conditions of high unmet need. EPPIC-Net conducts cutting-edge early phase clinical trials across the age and pain condition spectrum of pain therapeutics submitted by industry, academic, and other partners and accepted after rigorous review. EPPIC-Net provides access to a robust clinical trial network with expert infrastructure providing study design, conduct, and analysis at no cost to the applicant. The asset and intellectual property remain with the asset owner.

EPPIC-Net was established in 2019 when a Clinical Coordinating Center, a Data Coordinating Center and 12 Clinical sites were selected through a competitive process (RFA NS-19-023, RFA NS-19-024, RFA NS-19-025). Through discussion with stakeholders, the HEAL Partnership Committee, and the HEAL Multidisciplinary working group, an application process was developed to minimize preparation and submission burden on applicants.  Applications are reviewed by a dedicated EPPIC-Net review panel established by the NINDS Science Review Office to assure quality, transparency and fairness in the review process.  

EPPIC-Net Goals

EPPIC-Net seeks to enhance the treatment of acute and chronic pain and reduce reliance on opioids.

The goals of EPPIC-Net include:

  • Accelerating Phase 2 trials for pain therapeutics
  • Incorporating deep phenotyping into the trials
  • Providing well-characterized pain patient cohorts
  • Ensuring diverse and inclusive representation among researchers and participants
  • Continuous learning from experience to engineer adaptive, ever-improving early-phase testing of new pain therapies

To meet these goals, EPPIC-Net:

  • Provides stable infrastructure with the capacity to run multiple, high-quality trials concurrently.
  • Provides investigators and research staff with expertise across multiple pain conditions
  • Manages recruitment to enhance enrollment and minimize conflict between studies focused on similar conditions and similar populations
  • Promotes quality assurance
  • Supports a bio repository for storage and sharing of samples obtained during the course of EPPIC-Net clinical trials 
  • Works collaboratively with academia, non-profit, industry, and international partners

The EPPIC-Net Infrastructure, established through a competitive grant process, includes:

NIH EPPIC-NetHEAL and NINDS Leadership and EPPIC-Net NIH Program Staff interact with all EPPIC-Net components.

Clinical Coordinating Center (CCC) – The CCC provides overall organizational coordination for all of EPPIC-Net. The CCC takes the lead in protocol development, trial management, site/investigator selection, site/investigator training, reporting and interface with the EPPIC-Net central IRB.

Data Coordinating Center (DCC) – The DCC handles all aspects of data management, statistical support and analysis, quality assurance, and preparation of monitoring reports. The DCC provides the EPPIC-Net biorepository, serving all HEAL programs.

Specialized Clinical Centers (SCCs) – EPPIC-Net has selected 12 Specialized Clinical Centers, each consisting of an academic pain center (hub) and its affiliated clinical locations (spokes). SCC investigators bring specific pain expertise and participate in protocol development and implementation. Hubs and spokes conduct recruit focused pain populations, conduct research procedures, perform local monitoring and submit data to the DCC.

Applicant/Asset Provider: The applicant/asset providers are key collaborators in the EPPIC-Net trial for their asset. They provide the pain therapeutic (drugs/device etc.) for study and retain property rights to asset.

Current Studies

EN20-01 : A 24 week study to evaluate the safety and efficacy of CNTX-6970 in subjects with moderate to severe knee osteoarthritis pain


Abstract: The study will employ a randomized, allocation-concealed, multicenter, placebo-controlled, multi-period crossover design (Schmid et al, 2018). This multi-period crossover randomized, controlled trial allows comparability and assessment of efficacy through repeated exposures within each subject to the active treatment and a control (placebo) in randomized sequence. Such multi-period crossover designs are ideal for treatments with rapid onset of action and short half-life such as the asset under study here. We have strived to minimize the complexity of this powerful design by using only 2 blocks with 2 periods each. The modest additional complexity of the proposed multi-period crossover design, compared to a parallel-groups design, is justified by the marked improvement in efficiency. The gains in efficiency afforded by the multi-period crossover design allow a substantial reduction in sample size without sacrificing statistical power. For example, our simulation experiments (with sample sizes ranging from 30 to 50, carryover effects ranging from 0 to 0.2, and an effect size of 0.4) indicated that the parallel design yields statistical power ranging from 0.20-0.25, whereas our proposed 2-block multi-period crossover design yields power ranging from 0.9-1.0.

The trial will compare an active treatment vs. placebo. Each arm of the study will employ a multi-period crossover design with two blocks. Each block will consist of two treatment periods with each period lasting 6 weeks. Treatment assignments (active drug versus placebo) will be randomized for each patient to the two periods within each block. The period length of 6 weeks was chosen based on several considerations: (i) Most efficacious analgesic drugs demonstrate separation from placebo by 6 weeks; (ii) The decision to move CNTX-6970 forward to Phase 3 will require a clinically meaningful separation from placebo by 6 weeks; (iii) In this Phase 2 study, implementing a treatment block longer than 6 weeks would make the overall design more challenging and burdensome by extending the duration of overall testing beyond 6 months; (iv) Recent meta-analyses suggest that anti-inflammatory treatments such as NSAIDs reach peak effects on pain within a 4-week timeframe in patients with knee osteoarthritis, and multiple RCTs have specifically demonstrated efficacy for celecoxib at 2-6 weeks (Osani et al, 2020).

The comparison with celecoxib is used to evaluate "assay sensitivity," i.e., to assess the study protocol's ability to demonstrate superiority of an established efficacious treatment (celecoxib 100mg BID). In this study, the placebo will consist of inactive tablets identical to the active treatment tablets. Treatment assignments (active drug versus placebo) will be randomized for each patient to the two treatment periods within each block

  4. Submit Preliminary Application to EPPIC-Net via eRA Commons.

APPLICANTS WILL RECEIVE A SUBMISSION RECEIPT and NOTIFICATION OF DECISIONS ONCE REVIEW IS COMPLETE.

Following review, selected applicants are invited to proceed to Stage 2.

Stage 2: Prepare and submit DOSSIER application (invitation only)

Stage 2 invited applicants work with an NIH contractor to prepare a 15-20 page dossier with detailed information on the asset, including drug pharmacology and/or device specifications.

Upon completion of the dossier, submit the dossier application under ROA #OTA-20-002(pdf, 305 KB).

Applicants receive a submission receipt from eRA Commons. Applications are reviewed on a rolling basis. Applicants receive notification of decision from EPPIC-Net program staff once review is complete.

Following review, selected applications are invited to proceed to Stage 3.

Stage 3: Develop the clinical protocol. Submission by EPPIC-Net CCC (invitation only)

Applicants and asset holders must review and indicate their understanding of the terms and conditions for use of EPPIC-Net outlined in the EPPIC-Net Asset Owner Acknowledgement(pdf, 208 KB) before an application will move to protocol development. A written agreement between the CCC and the applicant/asset holder, defining the relationship, will also be put in place.

At stage 3, the applicant works with the EPPIC-Net CCC, in consultation with the EPPIC-Net DCC and appropriately-matched Specialized Clinical Centers to develop the clinical protocol. Once the protocol is prepared, the CCC submits the Stage 3 application for review. Protocols selected through review are presented to the NINDS Council and HEAL Leadership, who approve protocols for funding and study implementation within EPPIC-Net.

The CCC uses ROA #OTA-20-008 (pdf, 469 KB)to submit the Stage 3 protocol application.

EPPIC-Net Application Review Process

NIH promotes a process whereby applications submitted to the NIH are evaluated in a manner that is fair, equitable, timely, and free of bias. Independent, expert review  for EPPIC-Net applications is carried out by a Scientific Review Panel composed of federal and non-federal scientists with expertise in relevant scientific disciplines and current research areas.  The same Panel reviews EPPIC-Net applications at each stage (preliminary application, dossier application, protocol/OTA application), although a different subset of members may be present at each meeting.

Panel rosters are provided for information purposes only. Applicant investigators and institutional officials must not communicate directly with Panel members about an application before or after the review. Failure to observe this policy will create a serious breach of integrity in the review process, and may lead to sanctions, including withdrawal of the application.

View the EPPIC-Net OTA Review Committee Roster.

Independent review at each stage is followed by administrative review by NINDS for fit with the EPPIC-Net and NIH HEAL InitiativeSM  mission.

After Independent and administrative review, protocols may be proposed for funding. Selected protocols will then be reviewed by NINDS Council and the HEAL Executive Committee, who make the final decisions on funding. Decisions will be conveyed to the applicant by NINDS EPPIC-Net program staff.

IMPORTANT NOTES:

  • Stage 1 application is open to all; Stages 2 and 3 are by invitation only.
  • No funding is associated with application Stages 1 and 2.
  • Successful asset applicants receive access to EPPIC-Net resources for development and  conduct of the clinical trial for their asset. Asset applicants do not receive funding. Funding for selected clinical protocols is provided to the EPPIC-Net infrastructure components for conduct of the trial.
  • Intellectual property and products studied within EPPIC-Net remain the property of the asset owner
  • Data Ownership: The data generated through partcipation in EPPIC-Net are owned by the EPPIC-Net Clinical Research Site or entity that generated it.
  • Data Sharng: The Other Transactions award recipient (the CCC for EPPIC-Net clinical trials) and ther collaborators must and will comply with all NIH and HEAL Initiative Data Sharing polices established during the project period. These policies are outlined on the NIH websites:
