AMBITION study of ambrisentan/tadalafil combination therapy versus monotherapy achieves primary endpoint of time to first clinical failure event Data presented at the ERS International Congress 2014 GSK today announced that the first phase IIIb/IV study, conducted in collaboration with Gilead Sciences Inc., to investigate combination therapy of ambrisentan and tadalafil in treatment naïve patients with pulmonary arterial hypertension (PAH) met the primary endpoint (time to first clinical failure event) by showing superiority of the combination therapy compared to monotherapy treatment (ambrisentan or tadalafil).
| Use Case | Intended Effect | Typical Dosage | Onset Time | Duration of Action |
|---|---|---|---|---|
| Erectile Dysfunction | Improve erectile response | 40mg as needed | 30-60 min | Up to 36 hours |
| Pulmonary Hypertension | Relieve symptoms, reduce BP in lungs | 40mg daily or as prescribed | 15-30 min | 6-8 hours |
| Benign Prostatic Hyperplasia | Improve urinary flow | 40mg daily | 30 min | Up to 24 hours |
The length of time before patients experienced clinical failure was significantly prolonged for those receiving first-line combination compared to monotherapy. The randomised, double-blind, multicentre, ‘AMBITION’ study showed that first-line treatment of PAH with the combination of ambrisentan 10 mg and tadalafil 40 mg reduced the risk of clinical failure by fifty percent (50%) compared to pooled ambrisentan and tadalafil monotherapy arm (hazard ratio = 0.502; p=0.0002).
The combination was also statistically significant versus the individual ambrisentan and tadalafil monotherapy groups for the primary endpoint. Statistically significant improvements were also observed for three of the secondary endpoints (6 minute walk distance test, percentage of patients with satisfactory clinical response, change from baseline in N-terminal pro-B-type natriuretic peptide). The remaining two secondary endpoints (WHO functional class and Borg dyspnea index) did not meet statistical significance.
Rates of serious adverse events and events leading to discontinuation were similar across treatment arms. Detailed results from the study (Abstract #2916) were presented today during an oral session at the annual meeting of the European Respiratory Society (ERS).

GSK today announced that the first phase IIIb/IV study, tadalafil weekend pill conducted in collaboration with Gilead Sciences Inc., to investigate combination therapy of ambrisentan and tadalafil in treatment naïve patients.. “The data provided by the AMBITION study represent one of the most important steps forward in the treatment of patients with PAH” said Nazzareno Galiè, MD, Professor of Cardiology and Head of the Pulmonary Hypertension Centre, University of Bologna, Italy; Principal Investigator and Co-Chair of the AMBITION Steering Committee. “The 50% risk reduction for clinical failure achieved with upfront combination therapy as compared to upfront monotherapy, indicates that this combination treatment strategy could potentially become the standard of care in treatment naïve PAH patients with WHO/NYHA functional class II and III symptoms.” The companies now plan to seek approval for this combination indication by submitting the data from the AMBITION study to regulators in the United States (US), European Union (EU) and the rest of the world. “As part of our efforts to further help patients who suffer with this rare and debilitating lung disease, GSK and Gilead took a major step to jointly sponsor the first study to investigate whether there was an advantage to use upfront combination of ambrisentan and tadalafil compared to first-line monotherapy with either medicine” said Dr.

Ambrisentan, a selective endothelin type-A receptor antagonist, and tadalafil, a PDE-5 inhibitor, are each approved in the EU and other countries as once-daily treatments for PAH, (WHO Group 1) in patients with WHO/NYHA functional class II and III symptoms. In the EU, ambrisentan is indicated for the treatment of adult patients with PAH classified as WHO functional class II and III, to improve exercise capacity. Tadalafil is indicated in adults for the treatment of PAH classified as WHO functional class II and III, to improve exercise capacity.
Whether it is safe to take daily may depend on the reason and dose. If you're wondering, can I take 10mg of tadalafil daily? This is not the usual dosing for this diagnosis. Ultimately, your healthcare provider can help you answer the question, "How often should you take tadalafil?" On the other hand, if you are wondering, can I take 20mg of tadalafil daily? The answer may be yes if you have pulmonary artery hypertension.
Your healthcare provider is the best resource for determining how best to take the medication. Tadalafil is used for erectile dysfunction, benign prostatic hypertrophy, and pulmonary artery hypertension People who want more spontaneity in their intimate life may wish to take tadalafil daily rather than waiting 30-60 minutes after taking it to have sex Daily tadalafil may be used in people who have side effects from other erectile dysfunction medications or who have side effects from as-needed tadalafil You should avoid alcohol when taking tadalafil because it has a long half-life and can interact even hours later Tadalafil can interact with other medications and health conditions. These interactions can impact whether you choose to take tadalafil daily or as needed The daily dose of tadalafil is generally 2.5 or 5mg daily for benign prostatic hypertrophy and erectile dysfunction, and 20-40mg daily for pulmonary artery hypertension. Determining the correct dose of tadalafil to take daily depends on several factors, including the reason for taking it, your other health conditions, and your response to the medication. Your healthcare provider can help you determine the appropriate daily dosage of tadalafil.
The best time to take tadalafil daily is at a time that you will remember to take it consistently. For the as-needed form of tadalafil, you should take the medication at least 30-60 minutes before you plan to be sexually active and up to 36 hours before. Tadalafil can be taken with or without food, meaning it doesn't have to be taken at a specific time every day. It can take up to 3-5 days for daily tadalafil to build up in your system, so it's not necessarily a concern if you don't notice changes immediately. Taking any medication that you don't need increases your risk of side effects. PAH is a debilitating disease characterised by constriction of the blood vessels in the lungs leading to high pulmonary arterial pressures. These high pressures make it difficult for the heart to pump blood through the lungs to be oxygenated.
For tadalafil, taking the medication if you don't need it can increase your risk of side effects such as: Healthcare providers typically won't prescribe a medication unless it's needed, so if you are taking tadalafil unnecessarily, you may be at an increased risk of getting a medication that is counterfeit or contaminated. You should only take tadalafil, or any other prescription medication, under the supervision of a healthcare provider. In general, you should not skip a dose of any medication unless specifically instructed to do so by your healthcare provider. How safe it is to miss a dose of tadalafil depends on what you are taking it for. Missing a daily dose of tadalafil prescribed for pulmonary artery hypertension may have more health ramifications than missing a dose for BPH or erectile dysfunction.
Generally speaking, if you miss a dose of tadalafil, simply skip it and take the next dose at your normally scheduled time. Suppose you are taking tadalafil for pulmonary artery hypertension. In that case, your healthcare provider may recommend taking the medication as soon as you remember, provided it has not been too long since your last dose. If you are taking tadalafil daily, consult your healthcare provider or pharmacist about what to do if you miss a dose. You should not take an extra dose of medication unless you have been specifically instructed to do so by your healthcare provider.
The maximum approved dose of tadalafil is 40mg. This is usually used as needed for erectile dysfunction, but may also be used daily for people who have pulmonary artery hypertension. 60mg tadalafil is not an approved dose and may increase the risk of severe side effects. The only time you should take tadalafil 60mg is if a healthcare provider specifically prescribes it.

Patients with PAH suffer from shortness of breath as the heart struggles to pump against these high pressures, causing such patients to ultimately die of heart failure.
