Teva Announces Top-Line Results from Phase III Studies of Subcutaneously Administered Reslizumab in Patients with Severe Eosinophilic Asthma
Teva Pharmaceutical Industries Ltd., (NYSE and TASE: TEVA) today announced that a Phase III registration study evaluating subcutaneously administered reslizumab (110 mg) in a pre-filled syringe did not meet its primary endpoint of significantly reducing the frequency of clinical asthma exacerbations (CAEs) in patients with uncontrolled asthma and elevated blood eosinophils >300/mcL. A Phase III claim-support study evaluating subcutaneously administered reslizumab in patients with oral corticosteroid (OCS)-dependent asthma did not meet its primary endpoint of reduction in daily OCS dose.
“We are disappointed that these trials of the reslizumab formulation administered subcutaneously at a fixed-dose of 110 mg did not meet their primary endpoints. However, these results reinforce the role of eosinophils in severe asthma disease biology and the importance of defining the right blood eosinophil cutoff point for patient selection. We continue to see the positive impact of the intravenous formulation as a clinically effective 3mg/kg weight-based dosing option in patients with asthma and elevated blood eosinophils who are inadequately controlled on standard-of-care therapy,” said Tushar Shah, MD, Senior Vice President, Specialty Clinical Development and Medical Affairs at Teva.
In the registration study, a pre-specified a priori-powered subgroup analysis of 80% of the total randomized severe asthma patient population with baseline blood eosinophil count of ≥ 400/mcL showed significant reduction in CAE risk (p <0.025). this patient population is similar to those studied in the phase iii clinical trials for cinqair>®/CINQAERO® (reslizumab) injection, the currently approved intravenous formulation, which also used a blood eosinophil count of ≥ 400/mcL. 0.025).>
Teva will review the full data to determine next steps.
No new safety concerns to the known safety profile of reslizumab were identified in review of the data from these studies and no cases of anaphylaxis related to reslizumab were reported.
About the Studies
Study NCT02452190 was a registration Phase III, 52-week, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of reslizumab administered subcutaneously in 468 patients with uncontrolled asthma and elevated blood eosinophils. Its primary objective was to demonstrate the efficacy of reslizumab (110 mg) fixed, subcutaneous dosing every 4 weeks, as assessed by the reduction in frequency of clinical asthma exacerbations (CAEs).

Study NCT02501629 was a claim-support Phase III, 24-week, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of reslizumab administered subcutaneously in 177 patients with oral corticosteroid (OCS) dependent asthma and elevated blood eosinophils. Its primary objective was to demonstrate the efficacy of reslizumab (110 mg) fixed, subcutaneous dosing every 4 weeks, as assessed by reduction in daily OCS dose compared with baseline.

About CINQAIR®/CINQAERO® (reslizumab) injection for intravenous use
CINQAIR (reslizumab) Injection is an interleukin-5 antagonist monoclonal antibody (IgG4 kappa) indicated for add-on maintenance treatment of patients with severe asthma aged 18 years and older, and with an eosinophilic phenotype.
Limitations of Use: CINQAIR is not indicated for:
- treatment of other eosinophilic conditions
- relief of acute bronchospasm or status asthmaticus
IMPORTANT SAFETY INFORMATION
- Anaphylaxis has been observed with CINQAIR infusion in 0.3% of patients in placebo-controlled clinical studies. Anaphylaxis was reported as early as the second dose of CINQAIR.
- Anaphylaxis can be life-threatening. Patients should be observed for an appropriate period of time after CINQAIR administration by a healthcare professional prepared to manage anaphylaxis. Discontinue CINQAIR immediately if the patient experiences signs or symptoms of anaphylaxis.
- CINQAIR is contraindicated in patients who have known hypersensitivity to reslizumab or any of its excipients.
WARNINGS AND PRECAUTIONS
- Acute Asthma Symptoms or Deteriorating Disease: CINQAIR should not be used to treat acute asthma symptoms or acute exacerbations. Do not use CINQAIR to treat acute bronchospasm or status asthmaticus. Patients should seek medical advice if their asthma remains uncontrolled or worsens after initiation of treatment with CINQAIR.
- Malignancy: In placebo-controlled clinical studies, 6/1028 (0.6%) patients receiving 3 mg/kg CINQAIR had at least 1 malignant neoplasm reported compared to 2/730 (0.3%) patients in the placebo group. The observed malignancies in CINQAIR-treated patients were diverse in nature and without clustering of any particular tissue type. The majority of malignancies were diagnosed within less than six months of exposure to CINQAIR.
- Reduction of Corticosteroid Dosage: No clinical studies have been conducted to assess reduction of maintenance corticosteroid dosages following administration of CINQAIR. Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of therapy with CINQAIR. Reductions in corticosteroid dose, if appropriate, should be gradual and performed under the supervision of a physician. Reduction in corticosteroid dose may be associated with systemic withdrawal symptoms and/or unmask conditions previously suppressed by systemic corticosteroid therapy.
- Parasitic (Helminth) Infection: Eosinophils may be involved in the immunological response to some helminth infections. Treat patients with pre-existing helminth infections before initiating CINQAIR. If patients become infected while receiving treatment with CINQAIR and do not respond to anti-helminth treatment, discontinue treatment with CINQAIR until infection resolves.
- Adverse reactions that occurred at ≥2% incidence and more commonly than in the placebo group included 1 event: oropharyngeal pain (2.6% vs. 2.2%).
- Elevated baseline creatine phosphokinase (CPK) was more frequent in patients randomized to CINQAIR (14%) versus placebo (9%). Transient CPK elevations in patients with normal baseline CPK values were observed more frequently with CINQAIR (20%) versus placebo (18%) during routine laboratory assessments.
- Myalgia was reported in 1% (10/1028) of patients in the CINQAIR 3 mg/kg group compared to 0.5% (4/730) of patients in the placebo group.
- Immunogenicity: In placebo-controlled studies, a treatment-emergent anti-reslizumab antibody response developed in 53/983 (5.4%) of CINQAIR-treated patients (3 mg/kg). The antibody responses were of low titer and often transient. There was no detectable impact of the antibodies on the clinical pharmacokinetics, pharmacodynamics, clinical efficacy, and safety of CINQAIR.
