Thank you, Kyle. As a Phase 2 clinical stage pharmaceutical company, Atossa is now exclusively 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 2 trials and then evaluate further development independently or through partners and to advance one or more of our preclinical programs into the clinical trial stage. We accomplished much in the third quarter of 2016 that enables Atossa to proceed with our exciting drug development programs with a stronger foundation, including raising additional capital, regaining compliance with NASDAQ listing and exciting progress with our microcather fulvestrant study and oral endoxifen programs. Together with our settlement with Besins Healthcare and our recent capital raise of approximately $2.8 million, Atossa ended the quarter with over $4 million in capital which we are committing towards the development of our two drug programs. We also affected a 1-for-15 reverse stock split in August and regained NASDAQ listing compliance. These are excellent developments for Atossa in providing us the capability to exclusively focus on our drug development programs. We have two exciting Phase 2 programs in the breast cancer space. One that is in the clinical study and another that we are preparing for a Phase 2 trial. Our intraductal fulvestrant program is in the neoadjuvant setting, meaning the drug is administered before surgery. And 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. 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 is an FDA approved drug for breast cancer patients both to prevent recurrence as well as new breast cancers. We are very pleased to report that our intraductal fulvestrant microcatheter study was recently accepted for presentation at the San Antonio Breast Cancer Symposium being held December 6-10 2016. This prestigious symposium is designed to provide state-of-the-art information on the experimental biology, etiology, prevention diagnosis and therapy of breast cancer and pre-malignant breast disease to an international audience of academic and private physicians and researchers. The study has been accepted in the “ongoing clinical trials” category, which features studies that have not been completed and which does not permit the presentation of study results. As we discussed in our last quarterly call, our Phase 2 trial of fulvestrant by intraductal installation utilizes 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. Atossa’s microcatheters were invented by Dr. Susan Love, a world-renowned breast surgeon and were acquired by Atossa from Hologic. This study will assess the safety and tolerability of fulvestrant when administered 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 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 1 or 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 surgical specimen. This will help us assess the degree to which 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. You may recall Atossa owns an issued patent and several pending 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 intramuscularly injected drug and how it will compare to our introductally administered product. Going to again frame the potential market opportunity that’s successful 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 worldwide 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 is simply impossible to get this kind of tissue level when a drug is administered with the traditional intramuscular route. 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 IM administration. Doing so would save the healthcare system a lot of money and at the same time potentially improve 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 still a huge potential to obtain efficacy with much lower costs. Again crucial Atossa owns the issued patent for the intraductal use of fulvestrant, as well as many other pharmaceuticals. The second potential for use of our patented microcatheters is in the neoadjuvant setting, meaning that a drug would be delivered before the primary treatment of surgery. High drug concentrations 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 month or even two months could have immense value to the patient and the healthcare system. As I have mentioned previously with respect to the regulatory path forward, we expect that our program could qualify for a designation under what is called 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 the standard NDA program. For oral endoxifen being developed for breast cancer patients who are refract to tamoxifen thereby getting little or no benefit from taking tamoxifen, the initial drug supply is under development for manufacturer and we expect favorable developments which we will report as they occur. Our current plan is that we will conduct a small Phase 1 study and then proceed to a Phase 2 trial in 2017. We remain encouraged by our continued progress on both of these 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 or quarterly filing if we develop outside the U.S. which is anticipated to occur in 2017. I wish to thank our valued shareholders for their continued commitment and support. We are pleased with the achievements we have accomplished in the third quarter and are excited to proceed in advancing our goals of developing and commercializing treatments for breast cancer, DCIS and other breast diseases. This concludes our prepared remarks. I will now turn the call back to the operator for any additional questions.
