Study of Debio 4126, a new octreotide formulation, compared to placebo in patients with acromegaly who were previously treated with somatostatin analogs

1 1 1

What is this study about?

This clinical trial focuses on patients with acromegaly, a condition where the body produces too much growth hormone. The study evaluates a new medication called Debio 4126, which is a 12-week formulation of octreotide, compared to a placebo and other treatments. The purpose is to determine if Debio 4126 can effectively maintain normal levels of insulin-like growth factor 1 (IGF-1) in patients who have previously been treated with medications called somatostatin analogs.

The study involves three groups of participants. Some patients will receive Debio 4126 through intramuscular injection, while others will receive a placebo. The third group will receive Debio 4126 in an open-label manner, meaning both the doctor and patient know which treatment is being given. The medication will be administered every 12 weeks, and patients will be monitored for changes in their IGF-1 levels and overall health throughout the study period.

The treatment may also include other medications such as lanreotide for some participants. Throughout the study, doctors will monitor the safety of the treatment by checking various health parameters, including blood tests, vital signs, and the size of the pituitary tumor. They will also evaluate how well patients tolerate the injections by assessing any reactions at the injection site.

1 Initial treatment period (Period 1)

You will be randomly assigned to one of three treatment groups:

Group A: Receiving Debio 4126 injection every 12 weeks

Group B: Receiving placebo injection

Group C: Receiving Debio 4126 injection (open-label group)

This period lasts for 36 weeks

2 Blood tests at Week 34 and 36

Two blood samples will be taken to measure your IGF-1 levels (Insulin-like growth factor 1)

The average of these two measurements will determine if your condition is well-controlled

3 Treatment continuation (Period 2)

If your IGF-1 levels are within normal limits at Week 34, you may continue to Period 2

You may also qualify for Period 2 if your levels normalize with rescue medication by Week 48

4 Regular monitoring throughout the study

Regular checks of your: blood tests, vital signs, heart rhythm (ECG), and pituitary tumor size

Assessment of injection site for any reactions (redness, swelling, tenderness)

Monitoring of any side effects or adverse reactions

Pain assessment at injection site using a visual scale

5 Treatment administration

Debio 4126 is given as an injection into the muscle every 12 weeks

The medication comes as a ready-to-use suspension in different doses (30, 60, or 90 mg)

The study may continue until March 2029

  • Active or recent serious infections
  • Severe liver problems or abnormal liver function tests
  • Severe kidney problems or abnormal kidney function
  • History of cancer in the past 5 years (except treated skin cancer)
  • Participation in other clinical trials within the last 30 days
  • Mental conditions that could interfere with following study procedures

  • Serious heart conditions or recent heart problems
  • Active substance abuse or alcohol dependency
  • Inability to follow study procedures or attend scheduled visits
  • Use of medications that could interfere with the study drug

Investigated drugs:

Debio 4126
This is a new formulation of octreotide that lasts for 12 weeks. It is being studied for treating acromegaly, a condition where the body produces too much growth hormone. This medication belongs to a class of drugs called somatostatin analogs, which help control hormone levels in the body. The medication is designed to maintain normal levels of insulin-like growth factor 1 (IGF-1) in patients who have previously been treated with similar medications.

Octreotide
This is a well-established medication used to treat acromegaly. It belongs to the somatostatin analog class of medications that help regulate hormone production in the body. It works by reducing the levels of certain hormones, including growth hormone, that are elevated in people with acromegaly.

Investigated diseases:

Acromegaly – A hormonal disorder that develops when the pituitary gland produces too much growth hormone during adulthood. The condition causes gradual enlargement of body tissues, including hands, feet, facial features, and internal organs. The excessive growth hormone production is usually caused by a benign tumor in the pituitary gland. People with acromegaly may notice gradual changes in their appearance, including larger nose, lips, tongue, and wider-spaced teeth. The condition typically develops slowly over many years, with symptoms appearing so gradually that they often go unnoticed for a long time.
