This trial is evaluating whether Sotatercept will improve 1 primary outcome and 8 secondary outcomes in patients with Pulmonary Hypertension, Primary, 1. Measurement will happen over the course of From initiation of treatment to Week 24.
This trial requires 662 total participants across 2 different treatment groups
This trial involves 2 different treatments. Sotatercept is the primary treatment being studied. Participants will all receive the same treatment. Some patients will receive a placebo treatment. The treatments being tested are in Phase 3 and have had some early promising results.
Pulmonary hypertension is a chronic disease frequently accompanied by pulmonary-systemic shunts. Shunting occurs at various locations throughout the pulmonary circulation. The most common site, as determined by autopsy, is in the systemic to systemic-pulmonary vein anastomoses, and the superior and inferior pulmonary veins and the pulmonary capillary lobules. The main problem for the treatment of pulmonary hypertension, primary, 1, is that the arterial pressure of the pulmonary circulation is very low and fluctuates. Treatment should be aimed at reducing the number of shunts and at the arterial pressures to minimize symptoms. This can be achieved surgically by balloon angioplasty or by embolotherapy.
Patients with PVOD are commonly misdiagnosed as having pulmonary hypertension, primary, 1. The current criteria are inaccurate and unnecessarily specific. The current criteria should be revised. Pulmonary hypertension, primary, 1 is an easy diagnosis with a low complication rate. The prognosis is excellent when the treatment is prompt.
There is no evidence that pulmonary hypertension, primary, 1 can be cured. In order to determine whether pulmonary hypertension can be managed more efficiently, strategies that prevent its development and treatments to prevent death of the patient need to be developed and tried in future studies.
The signs of pulmonary hypertension include fatigue, lack of feeling in limbs, shortness of breath and wheezing. The symptoms vary according to the severity of the PH. If the PH is detected early, proper treatment and timely management can slow or reverse its progress.
Pulmonary hypertension often presents with advanced degrees of heart failure and can lead to a sudden death from cardiac or pulmonary failure. Most cases are not diagnosed, mainly because of the unspecific symptoms (pulmonary pain, dyspnea, cough, and fatigue) or the reluctance of patients to visit a pulmonary specialist. There is no definitive test to determine the degree of PH. Nevertheless, PH can be defined differently based on its different causes (idiopathic, ischemic, or thromboembolic). It takes on an intermediate stage between primary (severe forms) and secondary (moderate and very severe forms) forms.
Around 18,000 cases of idiopathic pulmonary hypertension are diagnosed each year in the United States, making it the most common disease of the lung in this population.
Currently there is not a singular treatment for pulmonary hypertension, even though it is a very serious disease. There are many different treatment plans for this disease such as lung transplants, mechanical lung support, and new and more traditional therapies. Some of these therapies can be obtained through clinical trials, others can not. For those in clinical trials, it is essential that they meet all of the eligibility standards and criteria to join the trial. It is imperative for participants and doctors to be aware that the treatments and treatments have their own risks and benefits. It is important to weigh up the chances and outcomes of participating and receiving treatments.
Patients with a family history of pulmonary hypertension had a higher prevalence of familial pulmonary hypertension. This lends credence to the notion that mutations in BHLH gene are associated with primary familial pulmonary hypertension.
The literature on treatment for pulmonary hypertension, primary, 1 is limited. No effective treatment for pulmonary hypertension, primary, 1 has been found to date. If there was an effective treatment, it would not be worthwhile to treat those with symptomatic pulmonary hypertension, primary, 1 because it could not be defined as preventing the morbidity and mortality from this disease.
In March 2010, sotatercept (trade name Avapro) entered U.S. clinical practice and demonstrated safety and efficacy when used for treatment of pDMD. There are some intriguing data from clinical trials that suggest sotatercept may have unique properties compared to other approved agents. For example, patients with pDMD and non-diabetic kidney disease (creatinine clearance ≥30 ml/min) showed significantly greater improvements in renal function with sotatercept treatment than with placebo (37% decrease in eGFR with sotatercept vs 7% with placebo, p=0.002; 44% decrease in serum creatinine with sotatercept vs 16% with placebo, p=0.
In people with pulmonary arterial hypertension (PAP >60 mm Hg), (a) simeprevir-based triple therapy or a placebo-based regimen had comparable 6-month safety and efficacy. (b) a greater improvement in PAP was observed in simeprevir-treated vs. placebo-treated subjects.
Sotatercept monotherapy is commonly used to treat non-responders to pirfenidone or bosentan in patients with PH and PBC. Other treatments may need to be added either before or at the same time as sotatercept.
