Hermann Lübbert: Yes. Thank you, Pamela. And thank you everyone for joining us this morning for Biofrontera's full-year 2018 earnings conference call. Today, I'm joined by our Chief Financial Officer, Thomas Schaffer, who will review our financials; and Christoph Dünwald, our Chief Commercial Officer, who’ll provide an update on our commercial products. Throughout 2018, Biofrontera successfully improved the clinical positioning and market potential of Ameluz in both the EU and the U.S., which helped to drive another record year of revenue. We are pleased with a 76% revenue growth rate and anticipate another robust year of growth. We have made great strides in the EU to return to strong growth with the approval and marketing of Ameluz to include daylight PDT for the treatment of actinic keratosis. In the U.S., we continue to significantly strengthen our presence, bolstering our sales team that has been able to increase their penetration into dermatology practices under an improved reimbursement environment. Furthermore, our initial public offering on the NASDAQ Capital Markets in February 2018 enhanced and validated our growing global presence. More recently, we have taken steps to transform Biofrontera from a highly specialized expert in PDT to a fully fledged specialty pharmaceutical company with a border focus in dermatology. Through our recent acquisition of Cutanea Life Sciences from Maruho, we have expanded our commercial portfolio to include two additional FDA approved prescription drugs, AKTIPAK and Xepi, which we will begin to leverage through our established sales and marketing infrastructure in the U.S. Our sales force shares our enthusiasm for the opportunity to expand our growth -- our product offering, which will in turn expand our reach and growth potential. As we look ahead, we also believe that the expanded branded generics development agreement with Maruho will help advance our future growth profile. More on that and our relationships with Maruho later on. Let me first highlight our clinical accomplishments in the U.S. and EU over the past year. We were very excited to recently announce positive results from our Phase 3 clinical trial, evaluating the safety and efficacy of conventional PDT with Ameluz for the treatment of AKs on the extremities, trunk and neck. The study was multicenter, randomized, double-blind, intra-individual and enrolled 50 patients at six study sites in Germany. Each patient had between 4 to 10 clinically confirmed AK lesions in comparable areas on the left -- right and left side of the extremities, trunk or neck, and mild, moderate and severe lesions were treated with one or two PDT treatments. The study met its primary endpoint, demonstrating that Ameluz was superior to placebo with a mean total lesion clearance rate of 86%, compared to 33% for placebo. In addition, the study met all secondary end points. When looking at complete clearance, 67% of the patients that are treated with Ameluz were completely cleared 12 weeks after the last PDT compared to 12% of the placebo treated sites. These secondary results helped to further support the primary endpoint, and we expect to file for label extension with the European Medicines Agency, EMA, and the U.S. FDA in the third quarter of this year. If approved, Ameluz would be the only PDT drug in Europe and the U.S. for treatment of actinic keratosis of all severities on the extremities, trunk and neck which would increase our competitive advantage over other PDT drugs on the market. In addition to the recent success in actinic keratosis, we initiated our U.S.-based Phase 3 trial evaluating Ameluz PDT for the treatment of superficial basal cell carcinoma. While we already have approval for BCC and the EU, after discussions with the FDA, the agency requested an additional placebo-controlled trial in the U.S. This trial is randomized, double-blind and placebo-controlled and we anticipate enrolling approximately 186 patients. We expect to complete patient recruitment for the study in the first half of 2020, and believe that if approved, this would make Ameluz the only PDT drug in the U.S. indicated for the treatment of superficial basal cell carcinoma, providing patients and physicians a highly efficacious and cosmetically acceptable alternative to surgery. Finally, to further support our anticipated growth of Ameluz, we were granted EMA and FDA approval to upscale the batch sizes for the production of Ameluz, which will increase production capacity fivefold, ensuring a secure supply of Ameluz as demand in the U.S. grows. Scaling the manufacturing process will also allow for a substantial improvement to our gross margins. With that, let me hand the call over to Christoph to discuss our commercial organization and its focus.
Christoph Dünwald: Thank you, Hermann. 2018 was also a very successful year for Biofrontera from a commercial perspective. We were pleased with another doubling of sales figures and were even able to increase our original sales forecast last fall. With over €21 million total sales and over 100,000 units sold, we have set new milestones in the Company's history. We saw two main drivers for the sales success in 2018, the European launch of Ameluz for daylight therapy; and the advancement of the U.S. market penetration. Let me take you through the development in Europe first. Once again, the sales trend was very positive in those European markets in which we operate with our own sales teams. In Germany, the largest European market for Ameluz, business developed very positively and Biofrontera was able to expand its market leadership in the segment of PDT drugs to a recent market share of approximately 66%. The main reason for this was the introduction of daylight PDT with Ameluz. The estimate that daylight PDT will conquer further market shares in the future and that were previously reserved for self-applied topical crèmes. What is particularly interesting is that Ameluz now finally reimbursed in Germany by the public health insurance funds when prescribed for daylight PDT. The number of patients who have access to treatment with Ameluz have therefore multiplied in 2018. We have used this to reposition ourselves in the German dermatology market. We have invested in marketing and sales and were able to observe that prescription for Ameluz in Germany increased by approximately 50% last year, a very promising trend. In Spain, the approval of daylight PDT has led to exceptional growth as well. After approval and reimbursement process lasting almost 18 months, the Spanish authorities granted us approval in July 2018 to market Ameluz for basal cell carcinoma. As a reminder, in Germany, we have been able to do so since the beginning of 2017. However, in Spain, we had to expect a 27% reduction in our sales price from July 1, 2018. We now have to compensate for this loss in margin by increasing volumes. With the approval of basal cell carcinoma, we also laid the foundation for taking our sales activities in England into our own hands. In England, it is more common to treat basal cell carcinoma than actinic keratosis and patients are referred by general practitioners to dermatologists who in the English health care system are mainly located in hospitals. We were able to win the core of the PDT sales team from our direct competitor Galderma for Biofrontera, and took very detailed and time consuming administrative steps in 2018 to position Ameluz once again in the English markets. Radically improved reimbursement situation for UK hospitals for PDT treatments has now come into force in April 2019, and Biofrontera should benefit from the new market opportunities. Let me come now to the U.S., our strongest growth market. As in previous financial year, our activities in the U.S. are the main component of our commercial success. By now, the U.S. sales team has grown to almost 40 employees. Our sales force is supported by seven scientific consultants, MSLs, our market access and manage market team, and the customer service team that has recently received a highly recognized award for its work. Over the past two years, we have sold more than $20 million worth of Ameluz in the United States, establishing the product in the marketplace. A key focus of our work in 2018 was to ensure the successful and correct reimbursement of Ameluz. Since the drug is purchased directly by the dermatologists as a so-called by and build drug, the reimbursement risk and the additional work involved in the reimbursement process remains with the physician. This initially reduced their willingness to stock up on larger quantities of Ameluz. The individual reimbursement codes, the so-called J-code for Ameluz was requested by Biofrontera in January 2017 and was issued in January 2018 according to the normal application deadline. With that, we have cleared another hurdle for the normalized reimbursement of Ameluz. Unfortunately, we encountered a brief erroneous restriction of reimbursement for Ameluz in the third quarter. However, this restriction was corrected retroactively to July 1, 2018, due to our intervention at CMS, the Center for Medicare and Medicaid Services. The final hurdle to a smooth reimbursement of our drug was the publication of the average selling price. Although Biofrontera has communicated this average price to the responsible authority every quarter since the launch in October 2016, the publication finally happened for the first time in January 2019. We therefore assume that the major problems with the reimbursement have finally been solved. Our customers have benefited from the increase in reimbursement for the work performed by physicians in connection with the PDT treatment. This reimbursement, the so-called CPT-codes, have been significantly increased and the physician-related -- excuse me, the physician relevant codes are now above reimbursement for cryotherapy, the previously preferred treatment for actinic keratosis in the U.S. This improved reimbursement will help us to better position PDT in the markets. After two years on the U.S. markets, we raised the price of Ameluz, in line with inflation for the very first time in October 2018. The price increase was accepted by our customers overall, but led to increase sales in September 2018. We estimate that Ameluz market share in the U.S. PDT drug segment is now around 18%, up from say 8% in 2017, and expect further market penetration this year. The U.S. revenue growth was exceptionally high at 136% in 2018. It is now important to introduce new to dermatologists to photodynamic therapy so that they can offer Ameluz to their patients. Last year, about 800 customers ordered Ameluz from us and the trend is rising. Many of our customers walk out of a clinic together with several other dermatologists. The top 30% of our customers spent on average about $60,000 on Ameluz last year. The visible success of our commercial strategy has contributed to the fact that Biofrontera has been given the opportunity to acquire Cutanea Life Sciences in the U.S. This has 2 advantages for us. First, with immediate effect we can sell two approved products, safety and Xepi and AKTIPAK in addition to Ameluz in the dermatology space; and second, by nurturing the sales teams, we can grow sales with the best employees of both organizations to a team of about 45 employees, sales reps, plus five regional managers. The goal is to successfully promote all three products to American dermatologists from July onwards with one integrated sales team. The targets for 2019 are ambitious, but we will again do our best to achieve them and thus lead by Biofrontera to break even. The success of 2018 is our inspiration for new records this year. And with that, I will hand over to Thomas for our financial review. Thomas?
