Thank you, Kyle. As Phase II clinical stage pharmaceutical company, Atossa is now solely focused on our pharmaceutical programs for the development of novel therapeutics and delivery methods for the treatment of breast cancer and other breast conditions. Our key objectives are to advance our pharmaceutical candidates through Phase II trials and then evaluate further development independently or through partners and to advance one or more of our preclinical programs into the clinical stage. I'll spend our time today discussing the progress we've made with our two therapeutic programs. We have two Phase II programs in the breast cancer space. One that is currently enrolling patients and another that we are preparing for a Phase II study. One program which we call intraductal fulvestrant is in the Neoadjuvant setting, meaning the drug is administered before surgery. The other program, which we call oral endoxifen for patients refractory to tamoxifen is in the adjuvant setting, meaning it would be administered after surgery. I will spend most of our remaining time talking about these two programs. In June 2016, we announced our oral endoxifen drug development program intended for breast cancer patients who are refractory to tamoxifen. Endoxifen is an active metabolite of tamoxifen, which itself is an FDA approved drug for breast cancer patients to prevent recurrence, as well as new breast cancers. We've made substantial progress on this program, having filed patent applications, contracted for the initial drug supply, and identified its initial indication. Breast cancer patients who are refractory to tamoxifen thereby getting little or no benefit from the drug. Of the estimated 1 million patients annually in the United States who take tamoxifen, up to 50% of those patients are refractory, meaning they receive little or no benefit from the drug for any number of reasons including low levels of a liver enzyme. We expect to initiate a Phase II clinical study for this drug in 2017. We are also progressing as planned with our Phase II trial of fulvestrant by intraductal administration utilizing Atossa's patented microcatheter device in estrogen receptor positive women with DCIS or invasive breast cancer slated for mastectomy or lumpectomy, which opened for enrollment in March 2016 after gaining IRB approval. Atossa's microcatheters were invented by Dr. Susan Love, a world-renowned breast surgeon and were acquired from Hologic. This study will assess the safety and tolerability of fulvestrant when delivered directly into breast milk ducts of these patients and is being conducted by Dr. Sheldon Feldman, current President of the American College of Breast Surgeons and Chief of breast surgery at Columbia-Presbyterian Hospital, in New York City. Providing drug directly into the ducts targeting the site of the localized cancerous lesions could reduce the need for systemic anticancer drugs and potentially reduce or even eliminate the systemic side effects of the drugs and the associated morbidity in such patients and ultimately improve drug regimen compliance. The primary endpoint of the clinical trial is to assess the safety and tolerability of intraductal administration of fulvestrant in women with DCIS or Stage I or Stage 2 invasive cancer prior to surgery. The secondary objective of the study is to determine if there are changes in the expression of Ki67, as well as estrogen and progesterone receptors between a pre-fulvestrant biopsy and post-fulvestrant surgery specimens. This will help us assess the degree that the drug is permeating the breast tissue. Mammography before and after drug administration in both groups will be performed to determine the effect of fulvestrant on breast density of the participants. Atossa owns one issued patent and several patent applications directed to the treatment of breast conditions including cancer by the intraductal administration of fulvestrant and other pharmaceuticals. In order to understand our main clinical program, it's important to understand the current uses and market for this FDA approved intramuscular injected drug and how it will compare to our introductally administered product. As we discussed in our last conference call, I want to again frame the potential market opportunity that's successfully developing our lead candidate conveys. According to the prescribing information, fulvestrant is administered monthly as an injection of two shots typically given into the buttocks. In 2012, a published study documented that the single-dose cost of intramuscular fulvestrant was approximately $12,000. Annual sales of fulvestrant are approximately $700 million and it is an important contributor to Astra Zeneca's oncology product revenue. So the first potential market for intraductal therapy is to take advantage of the huge difference in the amount of drug that gets into the tissue with the intramuscular injection versus the intraductal route. One analysis suggests that the drug levels in tissue might be over 20,000 times higher when administered intraductally. It's simply impossible to get this kind of tissue level when a drug is administered with the traditional intramuscular method. This high local dose provides the potential to test a one-in-done intraductal treatment modality instead of the monthly injections and to potentially obtain better tissue levels that are possible with intramuscular administration. Doing so would save the healthcare system a lot of money and at the same time potentially improving the safety and efficacy of the drug by delivering it directly to the breast. Even if it turned out the intraductal administration needs to be performed every six months, there is a huge potential to obtain efficacy with much lower costs. Again we have an issued patent for the intraductal use of fulvestrant, as well as many other pharmaceuticals. The second potential for use of our patented microcatheter is in the Neoadjuvant setting, meaning that a drug would be delivered before the primary treatment of surgery. High drug concentration at the site of tumor and lack of systemic exposure and subsequent toxicity could represent real treatment advances. The current Neoadjuvant schedules can run for three months before surgery and the ability to shorten that by one or even two months could have immense value to the patient and the healthcare system. As I’ve mentioned previously with respect to the regulatory path forward, we expect that our program could qualify for designation under the 505(b)(2) status, allowing us to file with clinical data only and without having to perform additional significant clinical or preclinical studies. So the path to market is both faster and less expensive than a standard NDA program. I’d now like to touch upon the recent settlement we achieved with Besins Healthcare on August 4, 2016. Atossa and Besins have agreed to terminate our intellectual property license agreement and dismiss the legal action relating to the license agreement settling all claims between us. We will have no further rights to clinical, regulatory, manufacturing, or proprietary information and all other development and commercialization activities with respect to 4-hydroxytamoxifen and Afimoxifene topical gel. Atossa gains reimbursement for the expenses we incurred during the AfTG program and a termination payment in the total amount of $1,760,000. We are pleased with this outcome and we will utilize these funds to drive our research and development related efforts in pursuing our drug development goals. We remain encouraged by our continued progress on both programs and as we pursue strategic initiatives that include completion of the oral endoxifen drug development efforts to support an IND filing to the FDA, which is anticipated to occur in 2017. I wish to thank our valued shareholders for their continued commitment and support. We are resolute in our passion to achieve our goals of developing and commercializing treatments for breast cancer, DCIS, and other breast illnesses and we will keep you informed of our latest developments and achievements as they occur. This concludes our prepared remarks. I'll now turn the call back to the operator for any additional questions.
