(sar-cli-sa)
Sanofi-Aventis U.S. LLC
Approval date: March 2, 2020


DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

SARCLISA is a drug used to treat a form of blood cancer called multiple myeloma. SARCLISA is for adult patients whose cancer returned or did not respond to, at least two previous treatments for multiple myeloma.

It is to be used in combination with two other drugs:

  • dexamethasone (a type of corticosteroid) and
  • pomalidomide.

 

How is this drug used?

SARCLISA is an injection. It is given by a healthcare profesional directly into the vein (intravenous infusion) every week for 4 weeks followed by every 2 weeks.

What are the benefits of this drug?

In the trial, patients who received SARCLISA (in combination with pomalidomadie and dexamethasone) lived longer without the cancer growing (average about 12 months) in comparison to patients who received pomalidomadie and dexamethasone combination only (average about 6 months).

What are the benefits of this drug (results of trials used to assess efficacy)?

The efficacy of SARCLISA was based upon progression-free survival (PFS).

Adapted from FDA Reveiw

How were the trials designed?

There was one trial that evaluated the efficacy and side effects of SARCLISA in patients with previously treated multiple myeloma. Patients were randomly assigned to receive either SARCLISA (in combination with pomalidomide and low-dose dexamethasone) or active comparator (pomalidomide and low-dose dexamethasone).Treatment was administered in both groups in 28-day cycles until disease progression or unacceptable toxicity. Both patients and health care providers knew which treatment was given.

The trial measured the time patients lived without the cancer growing (progression-free survival or PFS).

How were the trials designed?

The efficacy and safety of SARCLISA in combination with pomalidomide and low-dose dexamethasone were evaluated in a multicenter, randomized, open-label trial in patients who had had received at least two prior therapies including lenalidomide and a proteasome inhibitor. Patients were randomized in a 1:1 ratio to receive either SARCLISA in combination with pomalidomide and low-dose dexamethasone or pomalidomide and low-dose dexamethasoneTreatment was administered in both groups in 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). PFS results were assessed by an Independent Response Committee based on central laboratory data for M-protein and central radiologic imaging review using the International Myeloma Working Group (IMWG) criteria.

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 used in clinical trials 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.
