What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a special fluid called Axolotl Ambient, which is injected directly into the ankle joint. It aims to help people with ankle osteoarthritis by reducing pain and improving movement. The study will evaluate if this treatment really works and is safe.

Will I have to stop taking my current medications?

Participants must stop taking all prescription and over-the-counter pain medications for ankle osteoarthritis during the study, except for acetaminophen, which cannot be used for 3 days before and on the day of each follow-up visit.

Is the intra-articular injection of Axolotl Ambient safe for humans?

The research on intra-articular therapies, including gene therapies and other novel treatments, generally shows a favorable safety profile with minimal adverse effects in animal models. However, specific safety data for Axolotl Ambient in humans is not provided in the available research. ^{1 2 3 4 5}

How is the treatment Axolotl Ambient different from other osteoarthritis treatments?

Axolotl Ambient is unique because it is administered directly into the joint (intra-articular injection), which can increase the amount of the treatment available at the site of arthritis and reduce side effects compared to treatments taken by mouth. This method is different from traditional oral medications and may offer benefits like fewer side effects and potentially lower costs. ^{1 6 7 8 9}

What data supports the effectiveness of the treatment Axolotl Ambient for osteoarthritis?

Intra-articular injections, like those used in the Axolotl Ambient treatment, can be effective for osteoarthritis because they deliver medication directly to the affected joint, potentially increasing effectiveness and reducing side effects. Similar treatments, such as injections of autologous conditioned serum, have shown considerable symptom relief in clinical trials. ^{1 2 9 10 11}

Are You a Good Fit for This Trial?

Adults aged 18-79 with ankle osteoarthritis, experiencing chronic pain for at least 6 months and willing to stop most pain medications can join. Women must not be pregnant and use birth control. Exclusions include major prior ankle surgery, certain medical conditions like severe bone diseases or systemic inflammatory conditions, recent treatments with similar injections or steroids in the affected joint.

Inclusion Criteria

Signed written informed consent

I have had ankle pain for 6 months or more.

I am using or willing to use effective birth control methods until the final follow-up.

Exclusion Criteria

Pregnancy, breastfeeding, or woman of child-bearing potential not using adequate contraception

I have a bone deficit.

I am on prescription pain medication for a condition other than ankle osteoarthritis.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive a single intra-articular injection of either Axolotl Ambient or saline

1 day

1 visit (in-person)

Participants are monitored for safety and effectiveness after treatment

12 months

Follow-up at 4 weeks, 3 months, 6 months, and 12 months

What Are the Treatments Tested in This Trial?

Interventions

• 0.9% Normal Saline
• Axolotl Ambient

Trial Overview The study tests Axolotl Ambient, an intra-articular injection for ankle osteoarthritis pain relief against a saline placebo. Participants are randomly assigned to either the treatment or placebo group without knowing which one they receive (double-blind). The trial aims to assess safety and effectiveness of the drug.

How Is the Trial Designed?

Group I: Investigational Group Experimental Treatment 1 Intervention

Biological/Vaccine: Axolotl Ambient Axolotl Ambient is an allogeneic amniotic intraarticular injection therapy consisting of a growth factor and cytokine-rich fluid derived from human amnion cells. Other Names: • CA20

Group II: Control Group Placebo Group 1 Intervention

Single dose, 2.0 mL of 0.9% normal saline, administered via intra-articular injection administered to the affected tibiotalar joint.
