Thank you, Amy, and good morning to everyone. Let me get right into and update on the regulatory and development status of subcutaneous Relistor for chronic use. In July, we received from the FDA a Complete Response Letter, following its review of an sNDA for the subcutaneous Relistor for the treatment of opioid-induced constipation in adult patients with chronic non-cancer pain. We and colleagues from partner company Salix have since conducted an End-of-Review meeting with members of FDA's Gastroenterology division to gain clarity on the approval deficiency outlined in the CRL.
The CRL indicates a single approval deficiency related to the division's concern that there may be a risk associated with the chronic use of mu-opioid antagonists in patients who take opioids chronically for pain. Their concern is related to reports of signs and symptoms they believe may be caused by opioid withdrawal, for example, itching or piloerection or goosebumps, which was seen in a small number of patients. Progenics, reliant on data generated from validated assays and withdrawal administered during our clinical trials, does not believe that opioid withdrawal occurs when patients take Relistor.
The division's concern is that if it exists, opioid withdrawal could increase the risk of cardiovascular events in patients chronically taking Relistor. Baseline data from clinical trials of Relistor, including a year-long safety study and a review of that data by independent experts, we do not believe that there is an increase in cardiovascular events associated with the use of Relistor in this patient population.
In the End-of-Review meeting, the division communicated that in order to demonstrate that this risk does not exist, a very large, well-controlled chronic administration trial would be needed to assess the safety of Relistor prior to its gaining market approval for treatment of patients with OIC who are taking opioids for chronic non-cancer pain. In their discussions with the divisions, Salix expressed the view that the post-marketing clinical and pre-clinical data currently available for Relistor adequately demonstrate an appropriate and expected safety profile sufficient to permit the approval of d existing Relistor sNDA, and we agree with this assessment.
We plan to continue to work with FDA to generate a reasonable path forward for Relistor that can be agreed upon. While we can't definitively predict the duration of interactions with FDA regarding this matter, we are hopeful that a path forward will be determined during 2013.
In parallel, we expect Salix to file 4 marketing authorization in the European Union to expand the subcutaneous Relistor label to include patients with chronic non-cancer pain, based on the existing data package. It is important to note that the CRL and recent discussions with FDA focused on subcutaneous Relistor for patients with chronic non-cancer pain. Regarding the oral formulation, Salix is continuing its development work but will not file the NDA this year. And we will be in discussions with the FDA regarding the path forward for the oral formulation.
Turning our attention now to the already approved patient population, individuals with advanced illness. Relistor year-to-date global sales reported by our collaborators are $28 million, which represents a 53% increase over that period last year. Global sales reported by our collaborators for the third quarter were $4.9 million.
In the first and second quarters of this year, pre-filled syringes were introduced into the distribution channels, and Salix has told us that sales for those quarters reflected destocking. Now that the initial stocking of the pre-filled syringes is largely completed, third quarter reported sales were less as the distributors accessed that inventory. Salix has said that they see a growing trend in prescriptions and recently confirmed a current annualized run rate of $32 million and raised their estimate of peak year sales for sub-Q Relistor in the AI market. And as Salix announced yesterday, the FDA recently cleared an update to the advanced illness label.
