HOW TO USE THIS SNAPSHOT
The information provided in Snapshots highlights who participated in the key clinical trials that supported the original FDA approval of this drug, and whether there were differences among sex, race, age, and ethnic groups. The “MORE INFO” bar shows more detailed, technical content for each section. The Snapshot is intended as one tool for consumers to use when discussing the risks and benefits of the drugs.

LIMITATIONS OF THIS SNAPSHOT:
Do not rely on Snapshots to make decisions regarding medical care. Always speak to your healthcare provider about the benefits and risks of a drug.

Some of the information in this Snapshot is for presentation purposes and does not represent the approved conditions of use of this drug. Refer to the ENJAYMO Prescribing Information for all of the approved conditions of use of this drug (e.g., indication(s), population(s), dosing regimen(s), safety information).

Snapshots are limited to the information available at the time of the original approval of the drug and do not provide information on who participated in clinical trials that supported later approvals for additional uses of the drug (if applicable).

DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

ENJAYMO is a prescription drug that decreases the need for red blood cell (RBC) transfusion due to hemolysis (red blood cell destruction) in adults with cold agglutinin disease (CAD).

CAD is a rare blood disorder characterized by red blood cell destruction, which leads to anemia (a decrease in the number of RBCs) and cold-induced circulatory symptoms, such as pain and discoloration of fingers or toes. Many patients with CAD need RBC transfusions to manage their disease.

How is this drug used?

ENJAYMO is an infusion placed into a vein that is taken weekly for the first two weeks, followed by every two weeks thereafter.

Who participated in the clinical trials?

The FDA approved ENJAYMO based on evidence from one clinical trial of 24 patients with CAD. The trial was conducted at 16 sites in 8 of countries in Australia, Germany, France, Italy, Japan, Norway, United Kingdom, and the United States.

How were the trials designed?

ENJAYMO was evaluated in one clinical trial of 24 patients with CAD. This trial evaluated the benefit and side effects of ENJAYMO in patients with CAD. In this trial, patients had at least one blood transfusion within the past six months. Patients received ENJAYMO for up to six months and could choose to continue therapy in a second part of the trial. ENYAJMO was administered into the vein on Day 0, Day 7, and every 14 days through Week 25.

The benefit of ENJAYMO was evaluated based on response, which was defined by an increase in hemoglobin, no red blood cell transfusions after the first 5 weeks of treatment, and no other therapies for CAD as defined in the study.

What are the benefits of this drug?

After 6 months of treatment, 54% of patients responded to ENJAYMO. Response to treatment was defined based on changes on hemoglobin (Hgb) levels and whether a patient needed blood transfusion. Hgb is a protein in red blood cells that carries oxygen to tissues in the body.

Were there any differences in how well the drug worked in clinical trials among sex, race and age?

  • Sex: ENJAYMO worked better in female patients than male patients.
  • Race: Race was not collected in most patients therefore differences in how ENJAYMO worked among races was not determined.
  • Age: Differences in how well ENJAYMO worked among age groups could not be determined because of the small number of patients ≤65 years old.

What are the possible side effects?

ENJAYMO can cause serious infections, infusion-related reactions, and may increase the risk of developing autoimmune diseases. If ENJAYMO treatment is interrupted red blood cell breakdown may reoccur.

The most common side effects of ENJAYMO are respiratory tract infection, viral infection, diarrhea, dyspepsia (indigestion), cough, arthralgia (joint stiffness), arthritis, and swelling in the lower legs and hands.

Were there any differences in side effects of the clinical trials among sex, race, and age?

  • Sex: Differences in the occurrence of side effects between males and females could not be determined because of the small number of patients.
  • Race: Race was not collected in most patients therefore differences in side effects among races could not be determined.
  • Age: Differences in occurrence of side effects among age groups could not be determined because of the small number of patients ≤65 years old.

GLOSSARY

CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
