New Safety Data on treatment with COPAXONE® (glatiramer acetate) of Breastfeeding Mothers who Live with Relapsing Multiple Sclerosis: COBRA study presented at the 7th Congress of the European Academy of Neurology (EAN)

The COBRA study, a new real world evidence study undertaken by Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) and St. Josef Hospital (Bochum, Germany), was presented today at EAN congress and provided new insight on the use of COPAXONE® (glatiramer acetate or GA) by mothers with multiple sclerosis (MS) who are breastfeeding.

The study, which represents the largest analysis of child outcomes breastfed by mothers under GA, assessed 120 mothers with MS and their infants. It concluded that no evidence exists to suggest that infants were adversely affected by maternal exposure to glatiramer acetatewhile breastfeeding with regard to hospitalisations and antibiotic treatments, developmental delay, or growth in the first 18 months of life¹.

“The benefits of breastfeeding for both mothers and their offspring are clinically meaningful and well-documented, so it is imperative to provide clinical evidence on safety of disease modifying therapies (DMTs), so mothers with MS will no longer need to give up breastfeeding while on treatment ” said Professor Kerstin Hellwig, Principal Study Investigator, Department of Neurology, St. Josef Hospital, Ruhr University Bochum, Germany .

“Against the backdrop of the global COVID-19 pandemic, our analysis, which included 60 offsprings in the glatiramer acetate group and 60 in a control group (offspring of mothers with MS not treated with any disease-modifying treatment during breastfeeding), is an important contribution to this significant unmet medical need. There is historically limited clinical safety data for infants who are breastfed by mothers undergoing treatment for MS. We found no evidence of developmental delay, body growth issues or increased hospitalisation and antibiotic use in group of infants from the glatiramer acetate cohort in comparison with controls.

The COBRA study used data from the National German Multiple Sclerosis and Pregnancy Registry from 2011 to 2020. Patients were eligible for the study if they were diagnosed with relapsing MS (RMS), gave a live birth, were breastfeeding under GA treatment (Copaxone® 20 or 40 mg/mL) or breastfeeding under no DMT treatment.

Danilo Lembo M.D. VP Medical Europe, Teva Pharmaceuticals comments: “We are hugely grateful to this study for its work. According to data available, every third woman with MS may experience disease reactivation after childbirth ². Slowing disease progression, control of relapses and breastfeeding are priorities for many patients, especially in this particularly fragile period. Our mission at Teva is to improve the lives of patients. That includes helping to benefit from important medicines throughout life’s stages, and during family planning in particular.”

The data presentation follows extensive ongoing study of glatiramer acetate in a variety of real-world settings. For the past years, studies and leading MS experts have generally advised against the use of DMTs while breastfeeding infants and the postponing of breastfeeding for three months following the last dose of any disease-modifying drug³.

About the Study

“Real-world safety of Copaxone in Offspring of Breastfeeding and Treated Relapsing Multiple Sclerosis (RMS) pAtients” (COBRA study) was retrospective data analysis using the national German Multiple Sclerosis and Pregnancy Registry. 60 offspring from the glatiramer acetate (GA) cohort (59 pregnancies; 58 women) and 60 from the control (60 pregnancies; 60 women) were included. Maternal demographics and RMS prognostic factors were descriptively comparable between cohorts. “Cumulative” maternal GA-exposure was higher in the GA cohort vs control, because 86.7% of offspring’s mothers received GA also at some point during pregnancy (vs 25%).

Safety outcomes in ≤18 months of postpartum follow up showed similar between cohorts, offspring frequency and incidence of hospitalisations. Annualized number of hospitalisations was 0.20 [95% confidence interval {CI}=0.09–0.31] in the GA cohort vs the control (0.25 [95% CI=0.12–0.38]). Frequency and incidence of antibiotic use were similar between cohorts. Growth parameters (body weight, body length and head circumference) were also comparable between cohorts at birth as well as at each time point studied. Paediatrician check-ups at 12 months identified 3 (2.5%; N=120 [95% CI=0.52–7.13]) offspring with developmental delays; all in the control cohort (n=60; 5% [95% CI=1.04–13.92]).

About COPAXONE^®

COPAXONE^® (glatiramer acetate injection) is indicated for the treatment of patients with relapsing forms of multiple sclerosis. The most common side effects of COPAXONE^® are redness, pain, swelling, itching, or a lump at the site of injection, flushing, rash, shortness of breath, and chest pain. The use of COPAXONE® during breastfeeding should be decided by weighing the benefit of breastfeeding for the child and the benefit of therapy for the woman.
