Good afternoon everyone, and thank you Rob for that update. I would like to elaborate a little more on this much talked about concept of the totality of data, that we believe is so central to our optimism for a path forward towards BLA filing of Molgradex. There are a number of key factors. In fact, seven altogether, that are important in this consideration, which I will summarize one by one in a logical sequence. Firstly, it all starts with a thorough understanding of the disease mechanism of aPAP which is neutralization of GM-CSF by anti GM-CSF antibodies leading to surfactant accumulation and the resultant respiratory insufficiency and the failure. Treatment of aPAP with Molgradex, an inhaled form of GM-CSF is therefore a perfect fit mechanistically. Second, the concept has been shown to be very promising in uncontrolled academic studies and therefore based on this prior evidence, a treatment effect in a controlled study would not be unexpected. Third, we were indeed able to demonstrate that we can reverse the pathology of the disease and remove surfactant by showing a highly statistically significant improvement in the CT scans as measured by ground glass opacity scores with apparent dose frequency dependency. Number four, the removal of surfactant was associated with a reversal of the path of physiology that is the gas exchange impairment, as measured by two independent measures of gas change, the A-aDO2 and the DLCO. Number five, these changes correlated significantly with our key clinical endpoints of which there was a statistically significant and highly clinically significant treatment effect versus placebo in the SGRQ, a broadly used patient reported disease state assessment tool. Number six, the aforementioned changes were also associated with a reversal of a systemic, physiologic response to a chronic lung disease in the form of a decrease in hemoglobin. And finally, for each of these factors, most of the observed effect were dose frequency dependent, in other words, observed more clearly in the continuous treatment arm and less so in the intermittent dosing arm, providing further support to a true biological effect of the drug. Since our study was relatively small, not all of the observed differences were statistically significant, but the overall consistency of these results with a known biology of the disease is very convincing to us, and the sentiment is strongly shared by numerous KOLs as well as regulatory advisers. In the upcoming months, we will be completing the 24-week open label period of the study, which will give us an opportunity to evaluate if the improvements from baseline observed during the placebo controlled period have continued to increase. For many of the endpoints, the effect size appeared to be increasing over time as compared to placebo and the improvements did not appear to have plateaued at week 24. In particular, we are keenly interested to see if there has been further reduction in the frequency of whole lung lavage as treatment has continued, and if the placebo group will now flip to match or beat one or both of the active groups. We expect a lot of patients to have completed the open-label period in October and to have all data analyzed and summarized by early Q1 of next year. Wrapping up on the Molgradex aPAP program, I'm pleased to inform you that we continue to see strong enrollment into IMPALA-X our optional open-label extension study that allows patients to continue treatment for up to three additional years beyond the completion of the IMPALA study. At the end of Q2, 32 of 35 eligible patients had enrolled into the study and after running now for about one year, I am pleased to share that there have been no whole lung lavage reported and no drop outs to date. Moving on to other parts of our pipeline. There are two earlier stage clinical studies in our Molgradex franchise that are progressing in line with guidance. Both are Phase 2a open-label studies that are assessing Molgradex for the treatment of non tuberculosis micro bacterial or NTM lung infection. The OPTIMA study which initiated in March of 2018 and focuses on people who are not impacted by cystic fibrosis or CF is fully enrolled with 32 patients. We announced encouraging interim results from 14 patients last December, and continue to expect top line results in the first quarter of 2020. The ENCORE study which initiated earlier this year is very similar to OPTIMA but is enrolling people living with CF with a targeted enrolment of also approximately 30 subjects. Now let's next move to AeroVanc, our other pivotal Phase 3 program. AeroVanc is an inhaled vancomycin for treatment of methicillin-resistant Staphylococcus aureus or MRSA lung infection in people living with CF. Given the intense focus on the IMPALA study over the last few months, let me take a minute to remind you of the Phase 3 AVAIL study design. In Period 1, subject treated for three consecutive cycles of twice daily AeroVanc or placebo cycle being defined as 28 days of treatment, followed by 28 days of rest, with the primary endpoint being mean absolute change in FEV1 at weeks 4, 12 and 20 analyzed sequentially. In Period 2, all patients receive open-label AeroVanc twice daily for an additional three dosing cycles to evaluate the long-term safety of the drug. Importantly, the market opportunity with this program is quite large in the context of a rare disease. Above 30,000 people are affected by CF in the U.S. and MRSA infection has become increasingly common in CF with a prevalence of about 26%. Currently there are no approved inhaled therapies specifically targeting disinfection. As of August 1st, the AVAIL study had enrolled a total of 168 patients out of an initial target of 200. Enrollment of the adult population was complete already in Q3 of 2018, with 55 patients enrolled out of a target of 50. However, despite a clear improvement in enrollment rates, during the past quarter, enrollment of the primary analysis population, that is subjects between 6 and 21 years of age, continues to be challenging due to the severity of the disease. As of August 1st, the study had enrolled 113 pediatric patients out of a target of 150, leaving 37 left to go. As previously indicated, we continue to see a screening failure rate of approximately 50%. This is higher than anticipated and largely due to pulmonary exacerbations occurring between the time of screening and randomization, and failure to meet the required lung function criteria. However, these high screening numbers reinforce that we are clearly reaching a large number of patients affected by MRSA, and the exacerbations prior to randomization, demonstrate the high disease burden and the need for better treatment. While we have undertaken numerous activities to boost enrollments, including bringing on additional clinical study sites, the fluctuations in enrollments feed over time, has made it hard to give accurate guidance on enrollment completion. Accordingly, we are now revising enrollment completion guidance broadly to cover a range of projected enrollment rates with a new anticipated completion time for enrollment in the first half of 2020. This means top line results are now expected in late 2020 or early 21. We continue to prioritize this program and believe that AeroVanc can significantly improve outcomes for patients with MRSA. At last year's North American cystic fibrosis conference, the CF foundation made it very clear that despite advances in the disease modifying treatment, managing chronic infection and inflammation remain key challenges in the management of CF, and high priorities for new drug development. In fact, it is estimated that with increasing life expectancy associated with improving treatment options for CF, the absolute number of subjects with chronic infection is actually likely to increase over the years. Therefore, whether double and triple combination CF modulator therapies are clearly impactful there is still a high need for additional treatment approaches like AeroVanc to support the CF community. Finally, given the need to focus our attention on our later stage programs as well as conserve our cash resources, we completed a portfolio review and made the decision to deprioritize our exploratory amikacin/fosfomycin program. We will evaluate its potential for future development when we have the resources and bandwidth to do so. Now, I’ll pass the call to Dave for a financial update.
