With that, I would now like to turn the call over to Dr. Hermann Lübbert. Biofrontera's Chief Executive Officer. Hermann, go ahead.
Hermann Lübbert: Yeah. Thank you, Pamela. And thank you everyone for joining us today for Biofrontera's first quarter 2019 earnings conference call. Today, I'm joined by Christoph Dünwald, our Chief Commercial Officer, will provide an update on our commercial strategy, and our Chief Financial Officer, Thomas Schaffer, who will review our financials. Overall, 2019 is shaping up to be a very active year for Biofrontera and we are working diligently to ensure that it will be another year of operational and strategic success. In the first quarter, we increased total revenue by approximately 46%, primarily driven by the US and representing our first consecutive quarter of strong growth. These results continue to highlight our ability to execute on our strategic growth initiatives for Ameluz. Earlier this year, we reported positive results from our Phase III clinical trial, examining the safety and efficacy of conventional photodynamic therapy with mild to severe actinic keratoses with Ameluz for the treatment on extremities, trunk and neck. Patients were treated on one side of the body with Ameluz, on the other side with a placebo gel that was identical to Ameluz, but did not contain the active ingredient. The study which took place at six study sites in Germany met all primary and secondary endpoints, demonstrating that Ameluz was superior to placebo with a mean total lesion clearance rate of 86% compared to 33% for placebo. This result represents the primary endpoint of the study, but the study also shows highly significant results on all secondary endpoints. For example, at 12 weeks, after the last of one or two PDTs, 67% of patients who were treated with Ameluz were completely cleared of all the AK lesion compared to only 12% of the placebo treated ones. This compelling results helped to further support Ameluz as a highly efficacious therapy and we expect to file for label extension with the European Medicines Agency, EMA, and the US FDA in the third quarter of this year. If approved, Ameluz would be the only photodynamic therapy in Europe and the US for treatment of actinic keratosis of all severities on the extremities, trunk and neck, which would further increase our competitive advantage over other PDT drugs on the market. More recently, we announced a collaboration agreement with our strategic partner, Maruho, to continue our previous branded generics program and we have selected one of the four active ingredients tested under the earlier collaboration to prepare for clinical trials. Under the terms of the agreement, existing IP, specifically for Biofrontera's nanoemulsion technology remains with the original owner, while the results of the development are equally shared by both parties. Costs associated with the new project phase, up to €1.1 million, will be provided exclusively by Maruho. To use the results, Maruho will however still need to acquire a license for Biofrontera's nanoemulsion technology. In addition to this collaboration agreement, we also recently signed a nonbinding term sheet with Maruho for a joint research program for the label extension of Ameluz for the most severe forms of acne. As you remember, acne is an indication we have been exploring for the US market and believe it could be another significant growth opportunity for Ameluz. We are currently planning a proof-of-concept trial and a maximal use pharmacokinetic style, the cost of which would be borne by Maruho in an amount yet to be specified. These trials would be followed by at least two Phase III trials as required for the US marketing approval for acne. According to the term sheet, Maruho will also cover the costs of the Phase III trials and Biofrontera would grant Maruho a license for marketing Ameluz in parts of East Asia and Oceania. If both companies will not agree on such a license, Biofrontera will reimburse Maruho for the cost of the Phase III trials, provided the trials have been successful. We look forward to providing additional updates as this collaboration develops further. Let me know turn back to the acquisition of Cutanea. As briefly mentioned earlier, Cutanea has two FDA-approved prescription drugs – AKTIPAK and Xepi. AKTIPAK is a prescription gel for the treatment of acne and Xepi was approved last year as a prescription drug for the topical treatment of impetigo, a frequent bacterial skin infection. It's important to note that Xepi is the only drug in its class that is approved by the FDA also for the use with antibiotics resistant bacteria, such as MRSA. We have been working diligently to complete the integration of Cutanea in order to incorporate these two new products into our commercial portfolio and have our sales reps carrying them in their bag for which they are very excited. Up to the end of the current quarter, the two new products will still be marketed by the Cutanea sales team. Starting on July 1, a combined sales team will be responsible for marketing and selling of all three drugs. Since our last earnings call, we completed an important step in this transition period, which was the transfer of the US registration dossier of our NDA for AKTIPAK from Cutanea to Biofrontera. This transfer now makes us the authorized marketing holder for AKTIPAK. This means that we are now the primary contact for the FDA regarding AKTIPAK and will assume all responsibilities related to compiling and maintaining the regulatory dossier, informing the FDA about any changes related to the product and maintaining a pharmacovigilance system for the drug. Marketing authorization holder for Xepi is the Spanish company Ferrer and Biofrontera will assume all responsibilities with respect to the communication with the FDA. We are very excited to have these two additional drugs under the Biofrontera umbrella and believe we have the sales and marketing infrastructure and the necessary scientific and regulatory experience and know-how to market both products in tandem with Ameluz successfully. As outlined before, starting July 1, we expect to sell all three products with the combined sales force made up of our experience legacy sales representatives as well as a number of new sales representatives and sales trainers who are joining us from Cutanea. On that note, I would like to now hand the call over to Christoph to discuss our commercial progress.
Christoph Dünwald: Thank you, Hermann. Biofrontera has built a robust sales and marketing infrastructure in the US, Spain, Germany, and recently added a team in the UK. Our first quarter 2019 product sales were €6.8 million. This marks the highest quarterly revenues we accomplished so far in the company's history. Our sales teams globally contributed again to the success. Naturally, our largest market, the US, realized the largest contribution. Europe, however, is also continuing its dynamic growth due to the launch of daylight PDT last spring. Our goal is to expand the use of PDT in dermatology and the daylight PDT seems to capture the interest of more and more dermatologists in Europe. The workshops we are currently running in our three main European markets, Germany Spain and the UK, are well attended. But, first, let me talk about the development in the US where we continued to successfully execute our growth strategy. Initially, our team have been focusing on the low-hanging fruit, dermatologists who are already familiar with photodynamic therapy. Today, with total sales of over $30 million since the launch of Ameluz in October 2016, we can proudly say that we have established Ameluz and the BF-RhodoLED in the US market. US sales grew in the first quarter with 52%. With many reimbursement issues from the past now solved and the published average selling price that is adding simplicity to the reimbursement process, we are able to attract new customers to the PDT market. In the US, only 3% of the treated AK patients are treated with photodynamic therapy. This has to, and will, change and Biofrontera will be the driver of that growth. The recent acquisition of Cutanea gave us the possibility to realign our sales territories and we are now planning to cover the dermatology market in the US with a team of 45 sales employees, plus five regional managers. The team is supported by eight additional employees on the medical scientific side and four reimbursement specialists. Recruitment for all open positions is ongoing and we will take several members from Cutanea onboard. We are very pleased with the new sales talents. In terms of the newly acquired product, AKTIPAK and Xepi is taking place in June. And as of the 1 July, we will be working with one integrated sales force selling all products across the United States. Let's come to Europe now. We are very satisfied with the sales growth of 72% in Germany during the first three months. This growth momentum shows that we were able to gain more dermatologists prescribing and using Ameluz during the winter months. When not used in combination with natural daylight, dermatologists start to use Ameluz in daylight-simulated PDT with a variety of different labs. This means we are truly able to expand the market to new uses and the majority of that growth benefits Biofrontera through increased Ameluz sales. The sales for the rest of Europe remains flat year-over-year, which is due to the fact that we were able to control the reimport situation that skewed our numbers in the beginning of 2018. Business in Spain, strong. And we managed to compensate the price reduction of 27% we had to accept from the Spanish administration by increasing unit sales. Our UK team reports good progress with many public hospitals that put Ameluz on their formulary. With that, we anticipate an increasing sales momentum in the coming months. In addition, we continue to advance the use of Ameluz in the treatment of basal cell carcinoma and field cancerization in Europe. These approvals have not only expanded the market opportunities for Ameluz, but also have enabled the sale of Ameluz to hospitals where many European dermatologists practice. And, of course, the BCC indication adds to the reputation of Ameluz as a real cancer treatment. The acquisition of Cutanea is a fantastic opportunity to transform Biofrontera into a specialty pharmaceutical company in dermatology. We look forward to continue delivering strong growth and further strengthen Biofrontera. Our targets for 2019 are ambitious, but we would do, again, our best to achieve them and lead Biofrontera to breakeven. The success of 2018 is our inspiration for new records this year. We are off to a great start. And with that, I will hand over to Thomas for the financial review. Thomas?
