Question 1

What is Qalsody?

Accepted Answer

Qalsody is an antisense oligonucleotide designed to interfere with the production of a specific protein in the body. It works by binding to messenger RNA to prevent the translation of genetic instructions that lead to the buildup of this protein.

By reducing the levels of the targeted protein, the medication aims to impact the progression of certain biological processes at a molecular level. This mechanism is intended to address the underlying genetic drivers of a specific condition.

Question 2

What is Qalsody used for?

Accepted Answer

Qalsody is used to treat amyotrophic lateral sclerosis associated with SOD1 mutation .

Question 3

How does Qalsody work?

Accepted Answer

Targeting the SOD1 Gene

Qalsody is designed for individuals with amyotrophic lateral sclerosis (ALS) who have a mutation in the superoxide dismutase 1 (SOD1) gene. In people with this mutation, the body produces a defective or toxic version of the SOD1 protein. Over time, this protein builds up and damages the motor neurons, which are the nerve cells responsible for controlling muscle movement.

How the Medication Works

Qalsody is a type of medicine called an antisense oligonucleotide (ASO). It works by interfering with the genetic instructions the body uses to create the SOD1 protein. The process generally follows these steps:

Binding: After being injected into the spinal fluid, the medication binds to the specific messenger RNA (mRNA) that carries the instructions for making the SOD1 protein.

Degradation: Once the medication attaches to the mRNA, it triggers the body to break down those instructions before they can be used to build the protein.

Reduction: By destroying these instructions, the medication reduces the overall amount of toxic SOD1 protein produced in the body.

By lowering the levels of this toxic protein, the treatment aims to slow the progression of the disease. Clinical data has shown that treatment with Qalsody also leads to a reduction in neurofilament light chain, which is a biological marker in the blood that indicates nerve cell injury and death.

Question 4

What are the active ingredients in Qalsody?

Accepted Answer

The active ingredient in Qalsody is tofersen .

Question 5

What are the side effects of Qalsody?

Accepted Answer

Common side effects of Qalsody may include:

Upper respiratory tract infection

Headache

Fatigue

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Qalsody?

Accepted Answer

Qalsody belongs to the antisense oligonucleotide drug class.

Question 7

What is the dosage of Qalsody and how do I take it?

Accepted Answer

Administration Method

Qalsody is given as an intrathecal injection, which means it is injected directly into the space around the spinal cord. This procedure, known as a lumbar puncture or spinal tap, is performed by a healthcare provider in a clinical setting.

Treatment Schedule

The treatment typically follows a specific schedule divided into two phases:

Loading Phase: Patients receive several initial doses spaced a few weeks apart to build up the level of medication in the body.

Maintenance Phase: After the initial doses, the medication is administered less frequently at regular intervals to maintain its effects.

What to Expect During the Procedure

Before the injection, the healthcare provider will allow the medication to reach room temperature. During the procedure, the provider may remove a small amount of cerebrospinal fluid before injecting the medication. The injection itself usually takes a few minutes.

Missed Doses

If a scheduled appointment for a Qalsody injection is missed, it is important to contact a healthcare provider as soon as possible to reschedule. The provider will determine the best timing for the next dose and adjust the subsequent schedule if necessary.

Question 8

Is Qalsody safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate studies on the use of Qalsody in pregnant women to determine if there is a drug-associated risk of birth defects, miscarriage, or other adverse outcomes. In animal studies, no negative effects on the development of the fetus were observed in mice or rabbits at doses higher than the recommended human dose.

Breastfeeding

It is not known whether Qalsody passes into human breast milk, how it affects milk production, or if it has any effect on a breastfed infant. Research in animals has shown that the medication is present in the milk of lactating mice. If you are breastfeeding or planning to breastfeed, you should discuss the potential risks and benefits with your healthcare provider to determine the best course of action.

Question 9

What forms and strengths does Qalsody come in?

Accepted Answer

Qalsody is a sterile, preservative-free solution for intrathecal injection. It is administered directly into the fluid-filled space around the spinal cord by a healthcare professional.

This medication is supplied in vials. The solution is clear and colorless to slightly yellow.

Question 10

What is the FDA approval status of Qalsody?

Accepted Answer

FDA Approval Status

The FDA granted accelerated approval to Qalsody in April 2023. It is the first treatment for amyotrophic lateral sclerosis (ALS) to be approved based on the reduction of a biomarker, specifically plasma neurofilament light chain (NfL), which indicates nerve injury. This medication is indicated for adults with ALS who have a mutation in the superoxide dismutase 1 (SOD1) gene.

Accelerated Approval Requirements

Under the accelerated approval pathway, the FDA requires the manufacturer to conduct a confirmatory clinical trial. This trial is intended to verify that the reduction in NfL levels leads to a meaningful clinical benefit for patients. The FDA may withdraw approval if the confirmatory trial fails to demonstrate such benefits.

Safety Warnings

The FDA-approved labeling for Qalsody includes warnings for serious neurologic adverse reactions. Healthcare providers are advised to monitor patients for symptoms of:

Myelitis and radiculitis: Inflammation of the spinal cord or nerve roots.

Papilledema and increased intracranial pressure: Swelling of the optic nerve and high pressure within the skull.

Aseptic meningitis: Inflammation of the brain and spinal cord membranes not caused by infection.

There are currently no Boxed Warnings or Risk Evaluation and Mitigation Strategies (REMS) required for this medication.

Question 11

What should I know about Qalsody and cost?

Accepted Answer

Insurance and Out-of-Pocket Costs

The price of Qalsody can vary significantly based on your health insurance plan. Most insurance providers require prior authorization before they will cover this medication. Your out-of-pocket expenses, such as copays or coinsurance, will depend on your plan's specific benefits for specialty medications.

Administration Fees

Qalsody is administered through an intrathecal injection into the spinal canal by a healthcare professional. Because of this, the total cost of treatment includes not only the drug itself but also the professional fees for the medical procedure and the costs associated with the clinic or hospital visit.

Patient Assistance Programs

Financial assistance may be available through the drug manufacturer for eligible patients. These programs are designed to help reduce the cost of the medication for those with or without insurance. You can speak with your healthcare provider or contact the manufacturer directly to learn about support services and eligibility requirements.
