Study summary

The purpose of the study is to explore the safety, clinical effect, pharmacodynamics, and pharmacokinetics of CDX-0159 (barzolvolimab) in patients with Prurigo Nodularis.

Read the detailed description

The purpose of the study is to explore the safety, clinical effect, pharmacodynamics, and pharmacokinetics of CDX-0159 (barzolvolimab) in patients with Prurigo Nodularis.

There is a screening period of up to 2 weeks, an 8-week double-blind treatment period and a 16-week follow-up period after treatment. Patients will receive one dose of CDX-0159 (barzolvolimab) or placebo.

Eligibility criteria

Key Inclusion Criteria:

  1. Males and females, 18 - 75 years old.
  2. Diagnosis of Prurigo Nodularis by a dermatologist at least 3 months prior to Screening with:

    1. At least 20 PN nodules with bilateral distribution on both arms and/or both legs and/or both sides of the trunk at screening.
    2. An Investigators Global Assessment (IGA) score for PN ≥ 3 at screening and Baseline (Day 1).
  3. Severe itch, defined as the mean of the daily worst itch NRS (WI-NRS) score of ≥ 7 during the 7-day period immediately prior to initiation of study treatment.
  4. Documented history of inadequate response to prescription topical medications or for whom topical medications are medically inadvisable.
  5. Willing to apply a topical moisturizer (emollient) twice daily throughout the study.
  6. Both males and females of must agree to use highly effective during the study and for 150 days afterwards after treatment.
  7. Willing and able to complete a daily symptom electronic diary for the duration of the study and adhere to the study visit schedule.

Key Exclusion Criteria:

  1. PN due to neuropathy, psychiatric disorders or medications.
  2. Unilateral lesions of prurigo (eg, only one arm affected)
  3. Active unstable pruritic skin conditions in addition to PN.
  4. Women who are pregnant or nursing.
  5. Known or infection or active COVID-19 infection
  6. Vaccination with a within 2 months prior to study drug administration (subjects must agree to avoid vaccination during the study and for four months thereafter). NOTE: Inactivated vaccines are allowed such as seasonal influenza for injection. COVID-19 vaccination is allowed.
  7. History of anaphylaxis.

There are additional criteria that your study doctor will review with you to confirm you are eligible for the study.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

What researchers measure

Primary outcomes

  1. Safety and tolerability as assessed by the incidence and severity of adverse events

    Safety and tolerability of multiple dose levels of CDX-0159 as determined by drug related adverse events

    Time frame: From Day 1 (first dose) to Day 169 (last follow-up visit)

Secondary outcomes

  1. Pharmacokinetic evaluation

    CDX-0159 serum concentrations will be measured at specified visits

    Time frame: From Day 1 (before first dose) to Day 169 (last follow-up visit)

  2. Clinical effect of CDX-0159 on pruritus

    The mean percent change from baseline to Week 8 in the weekly average score of worst intensity itch per a numeric rating scale. The Worst Itch-Numerical Rating Scale (WI-NRS) ranges from 0 = "no itch" to 10 ="worst imaginable itch" for their worst intensity prurigo nodularis itch in the preceding 24-hr period.

    Time frame: From Day 1 (first dose) to Day 57 (week 8)
