About this study
Official title: Comparing the Risk and Severity of Infusion-Related Reactions in Patients Premedicated With Cetirizine Versus Diphenhydramine Prior to Ocrelizumab Infusions
This 6-month randomized controlled pilot study will determine whether there is some evidence that cetirizine is better tolerated than diphenhydramine without an increase in Infusion-Related Reactions (IRRs) in subjects receiving ocrelizumab(OCR) for multiple sclerosis (MS).
Read the detailed description
Ocrelizumab was approved by the US Food and Drug administration in March 2017 for the indication of Relapsing Remitting Multiple Sclerosis (RRMS) and Primary Progressive Multiple Sclerosis (PPMS). The landmark studies used to gain approval found ocrelizumab (OCR) to be well tolerated, but that at least one Infusion-Related Reaction (IRR) occurred in about one-third of patients. Because of this, neurologists typically prescribe prophylactic premedication with 100mg of methylprednisolone, 1 gram of acetaminophen, and 50 mg of IV diphenhydramine. However, many patients experience extreme sedation that interferes with their lifestyle considerably.
This 6-month randomized controlled pilot study will determine whether there is some evidence that cetirizine is better tolerated than diphenhydramine without an increase in IRRs. Fifty-two patients, 26 patients per arm, will be randomized in a 1:1 ratio to receive cetirizine or diphenhydramine as premedication prior to OCR infusions on day 0 (1st half dose of 300mg), day 14 (2nd half dose of 300mg) and week 24 (1st full dose of 600mg).

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Participants With Infusion-related Reaction (IRR) on Day 0
The proportion of patients having an infusion-related reaction (IRR), as defined by Common Terminology Criteria (CTCAE), version 4 during or after the first-half dose of the first infusion on day 0. IRRs are documented at the infusion clinic on the day of infusion and reported by the patient at the follow-up phone call the next business day after the infusion.
Measured: During or after the first-half dose of the first infusion on day 0
Secondary outcomes (7)
Proportion of Participants With Infusion-related Reaction (IRR) on Day 14
The proportion of patients having an infusion-related reaction as defined by Common Terminology Criteria (CTCAE), version 4 during or after receiving the second half dose infusion on day 14
Measured: during or after receiving the second half dose infusion on day 14.
Proportion of Participants With an Infusion-related Reaction (IRR) on Day 168
The proportion of patients having an infusion-related reaction as defined by Common Terminology Criteria (CTCAE), version 4 during or after receiving the first full 600mg dose infusion on week 168
Measured: during or after receiving the first full 600mg dose infusion on day 168.
Treatment Satisfaction Questionnaire for Medication (TSQM) Score on Days 0, 14 and 168
Patient reported outcome on Treatment Satisfaction Questionnaire for Medication. TSQM is administered within 2 hours after ocrelizumab (OCR) infusion, may be completed via phone to assess patient treatment satisfaction for the infusion. TSQM covers four domains: Global satisfaction, Effectiveness, Side effects, and Convenience. The scores are calculated for each of the subscales, ranging from 0 to 100. Higher score indicates higher satisfaction of the participant with the treatment and lower score indicates lower satisfaction of the participant with the treatment.
Measured: After the infusions on day 0, day 14, and day 168.
Stanford Sleepiness Scale (SSS) Score on Days 0, 14, and 168
Patient reported outcome on Stanford Sleepiness Score (SSS) administered prior to starting and within 2 hours after ocrelizumab (OCR) infusion, may be completed via phone. SSS measures sleepiness at specific times in a day. Participants will use a scale from 1 to 7 best representing their level of perceived sleepiness. The higher the score, the sleepier the subject and a lower score indicates the alertness of the subject.
Measured: after the infusions on day 0, day 14, and day 168.
Visual Analog Scale for Fatigue (VAS-F) Score on Days 0, 14 and 168
Patient reported outcomes on Visual Analog Scale for Fatigue, administered prior to starting and within 2 hours after ocrelizumab (OCR) infusion, may be completed via phone. The scale consists of various items relating to the participants' experience of fatigue and energy. Fatigue subscale ranges from 0-10 and a higher the score represents a greater fatigue for the participant. Energy subscale ranges from 0-10 and a higher the score represents a greater energy as perceived by the participant.
Measured: after the infusions on day 0, day 14, and day 168.
Modified Fatigue Impact Scale (MFIS) Score on Day 168
Modified Fatigue Impact Scale (MFIS) administered after the 2nd dose of OCR. Subject answers 21 questions (9 physical, 10 cognitive, and 2 psychological items) related to fatigue in the past 4 weeks with choices of frequency: 0: Never, 1: Rarely, 2: Sometimes, 3: Often, or 4: Almost always. The total MFIS score ranges from 0 to 84. A higher total score represents greater fatigue as perceived by the participants.
Measured: at day 168.
Multiple Sclerosis Impact Scale (MSIS-29) Score on Day168
Multiple Sclerosis Impact Scale (MSIS-29) is administered after the 2nd dose of ocrelizumab (OCR) infusion to evaluate the physical and psychological impact of multiple sclerosis (MS). Participants rate their symptoms related to MS as 1-Not at all, 2-a little 3-Moderately or 4-Extremely on the two subscales, 20-item physical subscale and 9-item psychological subscale. The two subscales are scored by summing the responses across items, then converting to a 0-100 scale using a formula. For both subscales, higher scores indicate higher impact of MS or greater disability for the participant.
Formula for physical impact subscale score: (100*(observed score-20))/ (100-20) Formula for psychological impact subscale score: (100*(observed score 9))/ (45-9)
Measured: at day 168.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing cetrizine and diphenhydramine in people with Multiple Sclerosis and Infusion Reaction, run by Providence Health & Services at 1 site 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 6 inclusion and 9 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 4 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 4 Mar 2024). 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?
Proportion of Participants With Infusion-related Reaction (IRR) on Day 0 (time frame: During or after the first-half dose of the first infusion on day 0). 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 NCT04175834, which also lists 7 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 4 Mar 2024; AzTrials last refreshed its copy on 7 Nov 2026.
