Trial Outcomes & Findings for A Study Evaluating B Cell Levels In Infants Of Lactating Women With CIS Or MS Receiving Ocrelizumab (NCT NCT04998851)

NCT ID: NCT04998851

Last Updated: 2026-01-14

Results Overview

Infant blood samples were collected at Day 30 after the mothers received their first postpartum ocrelizumab infusion (regardless of whether women receive a 600 mg or a 2x300 mg dose). The percentage of infants with B cell levels below LLN are reported with the two-sided Clopper Pearson 95% confidence interval (CI). B-cell reference ranges by week of life (absolute and percentage counts) are defined by Borriello et al. 2022.

Participant Flow

A total of 13 mother-infant pairs took part in the study across 7 sites in the United States, Spain, and the United Kingdom from 16 September 2021 to 13 January 2025.

Lactating mothers with clinically isolated syndrome (CIS) or multiple sclerosis (MS) who, in consultation with their treating physician, chose to continue or start postpartum treatment with commercial ocrelizumab were enrolled in this study. This study included a 60-day treatment and sampling period followed by an 11-month vaccination period.

Measure
Mothers
Lactating mothers initiating ocrelizumab received two doses of 300 milligrams (mg), as an intravenous (IV) infusion on Day 1 and Day 14, and mothers resuming ocrelizumab received a single dose of 600 mg, as an IV infusion on Day 1 at the discretion of the physicians, in accordance with local prescribing information.
Infants
Infants of mothers who received commercial IV ocrelizumab at the discretion of the physicians, in accordance with local prescribing information were observed until the last visit which was at 1 month (+ 30 days) after the first dose of measles, mumps, and rubella (MMR) vaccine (if first dose is administered at 11 months of age or later) or 1 month (+ 30 days) after second dose of MMR vaccine (if first dose is administered before 11 months of age), or at Month 13 of chronological age (+ 30 days) if MMR vaccine is not planned to be administered.

PRIMARY outcome

Timeframe: At Day 30

Population: Full Analysis Set Infants (FASI) included all the infants of women in the FASM population. Overall number of participants analyzed is the number of participants with data available for analyses.

Infant blood samples were collected at Day 30 after the mothers received their first postpartum ocrelizumab infusion (regardless of whether women receive a 600 mg or a 2x300 mg dose). The percentage of infants with B cell levels below LLN are reported with the two-sided Clopper Pearson 95% confidence interval (CI).

PRIMARY outcome

Timeframe: Up to Day 60

Population: Pharmacokinetic Analysis Set Mothers (PASM) included all mothers in the FASM with a breastmilk sample to allow measurement of ocrelizumab concentration.

ADID was calculated as the arithmetic mean of the mother's daily ocrelizumab milk concentration (micrograms/milliliters \[µg/mL\]) over 60 days post-ocrelizumab infusion 1 multiplied by an estimated infant milk intake of 150 milliliters/kilograms/day (mL/kg/day) and based on the weight \[kilograms (kg)\] recorded at the Day 30 visit. Ocrelizumab concentrations reported as below the lower limit of quantification \[LLQ=160 nanograms/millilitres (ng/mL)\] are imputed to zero for the calculation ADID.

SECONDARY outcome

Timeframe: Up to 1 month after the first or second dose of MMR vaccine (at approximately Month 13)

Population: AIRI included all infants in the SAFI for whom any serum titers of antibody immune response to vaccinations were available. Overall number analyzed are the number of infants with data available for analysis.

The immune response to DTP vaccine was assessed 1 month after the first dose of MMR vaccine (if the first dose is administered at 11 months of age or later) or 1 month after the second dose of MMR vaccine (if the first dose is administered before 11 months of age), or at Month 13 of chronological age if MMR vaccine was not planned to be administered. Cut-off Index (COI) = unitless ratio calculated as the signal intensity of the sample divided by the signal of the assay's cut-off calibrator. It is interpreted as follows: * COI \< 0.95: Negative * COI 0.95-1.04: Equivocal * COI \> 1.04: Positive The assay used has not been standardized against WHO International Units (IU/mL) for Bordetella pertussis IgG and therefore, cannot be converted to IU/mL. Higher COI values = a stronger antibody signal, but are not directly correlated with clinical protection. Positivity was defined using the manufacturer's COI cut-off (\>1.04).

Infants of mothers who received commercial IV ocrelizumab at the discretion of the physicians, in accordance with local prescribing information were observed until the last visit which was at 1 month (+ 30 days) after the first dose of MMR vaccine (if first dose is administered at 11 months of age or later) or 1 month (+ 30 days) after second dose of MMR vaccine (if first dose is administered before 11 months of age), or at Month 13 of chronological age (+ 30 days) if MMR vaccine is not planned to be administered.
Mean Titers of Bordetella Pertussis, IgG Antibody in Response to DTP Vaccine
1.12 COI
Standard Deviation 0.82

SECONDARY outcome

Timeframe: Up to 1 month after the first or second dose of MMR vaccine (at approximately Month 13)

Population: AIRI included all infants in the SAFI for whom any serum titers of antibody immune response to vaccinations were available. Overall number analyzed are the number of infants with data available for analysis.

The immune response to DTP vaccine was assessed 1 month after the first dose of MMR vaccine (if the first dose is administered at 11 months of age or later) or 1 month after the second dose of MMR vaccine (if the first dose is administered before 11 months of age), or at Month 13 of chronological age if MMR vaccine was not planned to be administered. This was to evaluate whether infants can mount humoral immune responses to clinically relevant vaccines.

1.23 IU/mL
Standard Deviation 0.43

SECONDARY outcome

Timeframe: Up to 1 month after the first or second dose of MMR vaccine (at approximately Month 13)

Population: AIRI included all infants in the SAFI for whom any serum titers of antibody immune response to vaccinations were available. Overall number analyzed are the number of infants with data available for analysis. Number analyzed refers to infants with data available for the specified IgG antibody titer.

The immune response to DTP vaccine was assessed 1 month after the first dose of MMR vaccine (if the first dose is administered at 11 months of age or later) or 1 month after the second dose of MMR vaccine (if the first dose is administered before 11 months of age), or at Month 13 of chronological age if MMR vaccine was not planned to be administered. Cut-off Index (COI) = unitless ratio calculated as the signal intensity of the sample divided by the signal of the assay's cut-off calibrator. It is interpreted as follows: * COI \< 0.95: Negative * COI 0.95-1.04: Equivocal * COI \> 1.04: Positive The assay used has not been standardized against WHO International Units (IU/mL) for Bordetella pertussis IgG and therefore, cannot be converted to IU/mL. Higher COI values = a stronger antibody signal, but are not directly correlated with clinical protection. Positivity was defined using the manufacturer's COI cut-off (\>1.04).
