About this study

Official title: THE PRIORITIZE STUDY: A Pragmatic, Randomized Study of Oral Regimens for Hepatitis C: Transforming Decision-Making for Patients, Providers, and Stakeholders

Phase 1 of this study compared the effectiveness of 3 approved DAA (direct-acting antiviral) HCV treatment regimens to learn whether they worked equally well under real-world conditions. Phase 2 of this study began early 2017 with removal of 1 DAA regimen, limiting randomization to just 2 FDA approved DAA regimens. Patients receiving HCV therapy in community and academic clinics were offered the opportunity to consent to be randomly assigned to one of three (phase 1) or one of two (phase 2) regimens and observed for outcomes. Once randomized, all medical care, laboratory testing, and any disease or side effect management were assumed by usual care conditions, and patient-reported outcomes were collected outside clinic in keeping with pragmatic design principles.

Read the detailed description

In Phase 1 of this study, consented patients were randomized to 1 of the following 3 HCV DAA treatments: 1) Harvoni® (SOF/LDV) 2) Viekira Pak™ (PrOD) 3) Zepatier™ (EBR/GZR) with the optional addition of Ribavirin (RBV) and the length of treatment determined by the individual provider.

In Phase 2 of this study, consented patients were randomized to 1 of 2 FDA approved HCV treatments: Harvoni® or Zepatier™. Both Phase 1 and Phase 2 subjects had up to 1 tablespoon of blood drawn for HCV resistance testing and future biorepository testing (following appropriate additional consent). The results of testing determined whether a genotype 1a subject randomized to Zepatier would be provided 12 or 16 wks of Zepatier.

Following enrollment/randomization, participants completed patient reported outcome questionnaires (PROs) via electronic device or telephone. Following baseline/randomization, participants were asked to complete surveys again at Wk 4 of treatment, End of Treatment, 1 and 3 year post treatment. Patients continued standard medical care throughout study. Data was abstracted from test results and medical records throughout treatment and for up to 3 years post treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sustained Virologic Response (SVR12) mITT With Imputation-Phase 1 and 2 EBR/GZR, SOF/LDV

    SVR (Sustained Virologic Response) 12 will be defined as undetectable hepatitis C virus (HCV) RNA at 12 week follow-up visit (12 -24 weeks after HCV treatment discontinuation at discretion of provider).

    mITT with imputation (missing=failure). Total number of subjects reflects participants from EBR/GZR with or without RBV and SOF/LDV with or without RBV randomized during Phase 1 and Phase 2.

    Measured: 12 weeks post-treatment

  2. Phase 1/2 Number of Participants With Sustained Virologic Response (SVR12-mITT Without Imputation)

    SVR (Sustained Virologic Response) 12 will be defined as undetectable hepatitis C virus (HCV) RNA at 12 week follow-up visit (12 -24 weeks after HCV treatment discontinuation as dictated by standard of care at each individual site).

    Number of subjects reflects participants who started EBR/GZR or SOF/LDV- based treatment (with or without RBV) during Phase 1 and 2.

    Measured: 12-24 weeks post HCV treatment

  3. Phase 1-Sustained Virologic Response (SVR12) mITT With Imputation

    SVR (Sustained Virologic Response) 12 will be defined as patients who have undetectable hepatitis C virus (HCV) RNA at 12 week follow-up visit (12 -24 weeks after HCV treatment discontinuation as dictated by standard of care at each individual site).

    mITT with imputation (missing=failure). Total number of subjects reflects participants from Phase 1 only.

    Measured: 12 weeks post-treatment

  4. Phase 1 Number of Participants With Sustained Virologic Response (SVR12-mITT Without Imputation)

    SVR (Sustained Virologic Response) 12 will be defined as undetectable hepatitis C virus (HCV) RNA at 12 week follow-up visit (12 -24 weeks after HCV treatment discontinuation as dictated by standard of care at each individual site).

    Number of subjects reflects participants randomized during Phase 1 only.

    Measured: 12 -24 weeks post-treatment

  5. Mean Change in Headache-PRO Scores -Phase 1

    Headache was evaluated by the HIT-6 score, a validated, Patient Reported Outcomes survey (PROs) 'PROMIS Headache Impact Test (HIT)' with scores ranging from 36 to 78 with higher score reflecting greater impact. Mean change in headache side effect was evaluated using difference between baseline value of HIT-6 score to the highest (worst) score during treatment. Estimates of mean change and differences obtained from a constrained longitudinal linear mixed-effects model that treated baseline score as one of outcomes. Negative values for mean change represent improvement in symptom.

    Measured: Baseline to On-Treatment

  6. Mean Change in Headache-EBR/GZR and SOF/LDV

    Headache was evaluated by the HIT-6 score, a validated, Patient Reported Outcomes survey (PROs) 'PROMIS Headache Impact Test (HIT)' with scores ranging from 36 to 78 with higher score reflecting greater impact. Mean change in headache side effect was evaluated using difference between baseline value of HIT-6 score to the highest (worst) score during treatment. Estimates of mean change and differences obtained from a constrained longitudinal linear mixed-effects model that treated baseline score as one of outcomes. Negative values for mean change represent improvement, while negative values for 'difference' indicate LDV/SOF performed better than PrOD

    Measured: Baseline to On-Treatment

  7. Median Change in Headache -Phase 1

    Headache was evaluated by the HIT-6 score, a validated, Patient Reported Outcomes survey (PROs) 'PROMIS Headache Impact Test (HIT)' with scores ranging from 36 to 78 with higher score reflecting greater impact. Median change in headache side effect was evaluated using difference between baseline value of HIT-6 score to the highest (worst) score during treatment. Estimates of mean change and differences obtained from a constrained longitudinal linear mixed-effects model that treated baseline score as one of outcomes. Negative values for change represent improvement, while negative values for 'difference' indicate LDV/SOF performed better than PrOD

    Measured: 12 weeks (Baseline and Average On-treatment Score)

  8. Median Change in Headache-Phase 2

    Headache was evaluated by the HIT-6 score, a validated, Patient Reported Outcomes survey (PROs) 'PROMIS Headache Impact Test (HIT)' with scores ranging from 36 to 78 with higher score reflecting greater impact. Median change in headache side effect was evaluated using difference between baseline value of HIT-6 score to the highest (worst) score during treatment. Estimates of median change and differences obtained from a constrained longitudinal linear mixed-effects model that treated baseline score as one of outcomes. Negative values for mean change represent improvement, while negative values for 'difference' indicate LDV/SOF performed better than PrOD

    Measured: Baseline -on Treatment (12-16 weeks)

  9. Mean Change in Nausea/Vomiting PRO Score -Phase 1

    Patients completed the PROMIS® Nausea Short Form at Baseline (T1) and on-treatment. PROMIS raw scores from each of the completed questionnaires were converted to standardized T-scores. Change was calculated as the difference between baseline and on-treatment score. T-scores for the PROMIS Nausea and Vomiting 4a scale range from 45.0 - 80.1. Higher scores indicate worse nausea. Negative values for mean change represent improvement.

    The estimates of mean change and differences were obtained from a constrained longitudinal linear mixed-effects model that treated the baseline score as one of the outcomes. The model expressed mean score as a function of DAA regimen, cirrhosis status, HCV genotype, sex, age, race, and previous treatment status.

    Measured: Baseline to On-Treatment

  10. Mean Change in Nausea/Vomiting PROMIS Score -EBR/GZR vs. LDV/SOF

    Participants completed the Patient Reported Outcomes surveys (PROs) 'PROMIS Nausea/Vomiting -4 Short Form' at baseline and during treatment. Raw scores are converted to standardized T-scores with a range of 45.0-80.1. Higher scores indicate worse nausea/vomiting.

    Results presented as mean difference from baseline to average of on Treatment Scores (highest/worst) score during treatment.

    A negative (-) PROMIS change score is suggestive of symptom improvement or lack of drug side effect. Estimates of mean change were obtained from a constrained longitudinal linear mixed-effects model that treated the baseline score as one of the outcomes.

    Measured: Baseline and Average On-Treatment Score

  11. Median Change in Nausea PRO Score -Phase 1

    Patients completed the PROMIS® Nausea Short Form at Baseline (T1) and on-treatment. PROMIS raw scores from each of the completed questionnaires were converted to standardized T-scores. Change was calculated as the difference between baseline and on-treatment score. T-scores for the PROMIS Nausea and Vomiting 4a scale range from 45.0 - 80.1. Higher scores indicate worse nausea. Negative values for mean change represent improvement.

    The estimates of change and differences were obtained from a constrained longitudinal linear mixed-effects model that treated the baseline score as one of the outcomes.

    Measured: Baseline to end of treatment

  12. Median Change in Nausea PROMIS Score-EBR/GZR SOF/LDV

    Patients completed the PROMIS® Nausea Short Form at Baseline (T1) and on-treatment. PROMIS raw scores from each of the completed questionnaires were converted to standardized T-scores. Change was calculated as the difference between baseline and on-treatment score. T-scores for the PROMIS Nausea and Vomiting 4a scale range from 45.0 - 80.1. Higher scores indicate worse nausea. Negative values for change represent improvement.

    The estimates of change and differences were obtained from a constrained longitudinal linear mixed-effects model that treated the baseline score as one of the outcomes.

    Measured: Baseline- On Treatment (up to 16 weeks)

  13. Mean Change in Fatigue PRO Score -Phase 1

    Fatigue severity collected from validated, Patient Reported Outcomes survey (PROs), 'PROMIS Fatigue Short Form'. PROMIS® T-scores were computated to compare difference between baseline value of PROMIS score to the highest (worst) score during treatment. Results presented as computated t-score from baseline to average of on Treatment Scores. A positive (+) score suggests improvements in functional well-being. A negative (-) PRO change score is suggestive of symptom improvement or lack of drug side effect. PROMIS Fatigue Score scale per question: 1=Never, 2=Rarely, 3=Sometimes, 4=Often, 5=Always with 7 questions for a total maximum score of 35.

    Measured: Baseline to On-treatment

  14. Mean Change in Fatigue PRO -EBR/GZR vs SOF/LDV

    Fatigue severity collected from validated, Patient Reported Outcomes survey (PROs), 'PROMIS Fatigue Short Form'. PROMIS® T-scores were computated to compare difference between baseline value of PROMIS score to the highest (worst) score during treatment. Results presented as computated t-score from baseline to average of on Treatment Scores. A positive (+) score suggests improvements in functional well-being. A negative (-) PRO change score is suggestive of symptom improvement or lack of drug side effect. PROMIS Fatigue Score scale per question: 1=Never, 2=Rarely, 3=Sometimes, 4=Often, 5=Always with 7 questions for a total maximum score of 35.

    Measured: Baseline and Average On-Treatment Score

    Measured: Baseline-On Treatment (up to 16 weeks)

  17. Mean Change in HCV- PRO- Phase 1

    HCV-PRO, a survey for patients with HCV that measures physical, emotional, and social functioning, productivity, intimacy, and perception of quality of life, was used to assess 'overall functioning and well-being'. In general, lower score is worst outcome and higher scores indicate greater well-being and functioning. However, for ease of interpretation, HCV-PRO scale has been transformed by using '100 - HCV-PRO' ultimately revising the score to mean 0 (lowest score) is best to 100 (worst outcome). A positive change (End of treatment to baseline) suggests improvements in functional well-being.

    Total score = (SUM-N)/(4*N)*100, where N is the number of questions answered.

    Measured: Baseline to End of Treatment

  18. Median Change in HCV-PRO (Overall Well Being) -Phase 1

    HCV-PRO, a survey for patients with HCV that measures physical, emotional, and social functioning, productivity, intimacy, and perception of quality of life, was used to assess 'Overall Functioning and Well-being'. In general, lower score is worst outcome and higher scores indicate greater well-being and functioning. However, for ease of interpretation, HCV-PRO scale has been transformed by using '100 - HCV-PRO' ultimately revising the score to mean 0 (lowest score) is best to 100 (worst outcome). A positive change (End of treatment to baseline) suggests improvements in functional well-being.

    Total score = (SUM-N)/(4*N)*100, where N is the number of questions answered.

    Measured: Baseline to End of Treatment

  19. Mean Change in HCV-PRO (Functional Well-being) EBR/GZR vs. SOF/LDV Score-Phase 2

In general, lower score is worst outcome and higher scores indicate greater well-being and functioning. However, for ease of interpretation, HCV-PRO scale has been transformed by using '100 - HCV-PRO' ultimately revising the score to mean 0 (lowest score) is best to 100 (worst outcome). A positive change (End of treatment to baseline) suggests improvements in functional well-being.

    Total score = (SUM-N)/(4*N)*100, where N is the number of questions answered. End of Treatment -Baseline were used to calculate CHANGE in outcome. Number of subjects reflects participants from both Phase 1 and 2.

    Measured: End of Treatment - Baseline

  20. 16 Wk EBR/GZR With RBV Efficacy on Patients With HCV RASs

    Efficacy of Hepatitis C Virus (HCV) Treatment with Zepatier (Elbasvir/Grazobevir) with Ribavirin (RBV) for 16 weeks when used in Genotype 1a patients with Baseline RASs (NS5a Resistance Associated Substitutions or RAPs -Resistance Associated Polymorphisms).

    Efficacy defined as HCV RNA undetectable 12 weeks post treatment. Table excludes Genotype 1b patients.

    Measured: 12 weeks post treatment

Secondary outcomes (8)
  1. Treatment Non-Adherence Probability Estimates

    The Voils Medication Adherence Survey (VMAS) was used to evaluate medication adherence during HCV treatment. Participants responded to three questions about the extent of adherence during the past seven days of treatment (during early and late on-treatment occasions). Participants responded using a five-point ordinal scale of missed dosing from 1 (none of the time) to 5 (all of the time). On each occasion participants were coded as being "Non-adherent" if any response was > 1, otherwise they were coded as "Adherent". Probability estimates of percentage of patients reporting non-adherence were calculated per HCV treatment (Direct Acting Antiviral-DAA) regimen: 1)EBR/GZV (elbasvir/grazoprevir, 2)SOF/LDV (sofosbuvir/ledipasvir), 3)PrOD

    Measured: 12-16 weeks of HCV treatment

  2. Change in HCV-associated Symptoms (PROMIS Measures) After HCV Treatment Initiation

    Change in HCV-associated symptoms was calculated as the mean differences of mean scores from multiple surveys from the NIH Patient-Reported Outcomes Measurement Information System (PROMIS)-- Fatigue, nausea, belly pain, sleep disturbance, and diarrhea) and functional status (well-being) when comparing baseline to early post-treatment and late post treatment surveys. Mean change scores were calculated by comparing baseline to early post-treatment (1 yr) and late post-treatment (approximately 3 years) surveys. T-scores for the PROMIS Nausea and Vomiting 4a scale range from 45.0 - 80.1. Higher scores indicate worse nausea. Negative values for mean change represent improvement.Negative numbers suggest better symptoms (improvement in HCV-associated symptoms). PROMIS Fatigue Score scale per question: 1=Never, 2=Rarely, 3=Sometimes, 4=Often, 5=Always with 7 questions for a total maximum score of 35.HCV-PRO positive estimates suggest baseline functional well-being improvement.

    Measured: 1 year post treatment discontinuation (Early post-tx)

  3. Post-treatment Progression/Regression of Liver Disease-Fib-4

    Mean change (delta) in FIB-4, an indirect non-invasive measure of liver fibrosis, calculated as baseline median -long term follow up median, following SVR after any of the study treatment regimens. Change in FIB-4 where negative values indicate improvement in liver fibrosis score and positive values indicate worsening of fibrosis score. There is no upper or lower limit for change. FIB-4 = age (years) * AST(IU/L)/Platelets (10^3/L) * ALT^.5(IU/L). In general, Score of 0-1.29 is low risk for advanced fibrosis, 1.30-1.67: intermediate risk for advanced liver fibrosis, >2.67: high risk for advanced fibrosis.

    Measured: Baseline to up to 3 years post treatment discontinuation

  4. Change in Functional Status (HCV-PRO) Within Treatment

    HCV-PRO score, a validated PROMIS survey used to evaluate overall functioning and well-being in HCV patients, was utilized to compare long-term 'within treatment' changes of functional well-being. In general, lower score is worst outcome and higher scores indicate greater well-being and functioning. However, for ease of interpretation, HCV-PRO scale has been transformed by using '100 - HCV-PRO' ultimately revising the score to mean 0 (lowest score) is best to 100 (worst outcome). A positive estimate (Post treatment to baseline) suggests baseline functional well-being improvement.

    Total score = (SUM-N)/(4*N)*100, where N is the number of questions answered.

    Measured: Treatment start date up to 2 years post-treatment

  5. Number of Participants With Adverse Events That Caused Treatment Discontinuation-EBR/GZR vs. LDV/SOF

    The number of participants with adverse events that led to early treatment discontinuation (defined as duration less than originally prescribed treatment regimen)

    Measured: Treatment start date through treatment completion (up to 24 weeks)

  6. HCV SVR Durability -No Cirrhosis

    Number/Percentage of patients with persistence of viral cure, SVR (SVR = Sustained Virologic Response)- defined as undetectable HCV RNA at least 24 weeks following HCV Treatment.

    Measured: 24 weeks post-end of treatment up to 153 weeks

  7. HCV SVR Durability-Patients With Cirrhosis

    Percentage of Cirrhotic patients with persistence of viral cure, SVR, (SVR= Sustained Virologic Response) defined as undetectable HCV RNA at least 24 weeks following HCV Treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing SOF/LDV (sofosbuvir/ledipasvir), PrOD (ombitasvir/paritaprevir/ritonavir with dasabuvir) (Phase 1 only) and EBR/GZR (elbasvir/grazoprevir) in people with Chronic Hepatitis C, run by University of Florida at 38 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 38 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sustained Virologic Response (SVR12) mITT With Imputation-Phase 1 and 2 EBR/GZR, SOF/LDV (time frame: 12 weeks post-treatment). The study lists 20 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02786537, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2021.
