Thanks, Monique, and good afternoon, everyone. Thanks for joining us today. We are happy to be here with another update of our progress.
I'm quite pleased to announce that just a few days ago, our final pilot study in bronchiolitis or BRO opened in Israel, and we treated our first patient today. Thanks to the great team in Israel for achieving this goal on schedule.
To remain on track to complete our pivotal BRO study with the LungFit BRO system in the U.S. in the second quarter of calendar 2021, we are deferring our U.S. Premarket Approval or PMA submission of the LungFit system for persistent pulmonary hypertension of the newborn or LungFit PH by 1 quarter to the first quarter of 2020. This decision also allows us to keep our At-Home self-administration NTM study on track for a spring 2020 start.
Let me give you a few more details on our decision to prioritize LungFit BRO and LungFit NTM over the LungFit PH in the very short term. Given the breadth of our development opportunities for the LungFit system and the current limitations of our resources, at times we are required to address the needs of our development programs on a sequential basis, we decided to elevate the prioritization of LungFit BRO and LungFit NTM. Preparing the U.S. Investigational Device Exemption or IDE submission for LungFit BRO before filing our PMA for LungFit PH does not materially change our anticipated launch timing for LungFit PH, which is scheduled for the fall of 2020. By elevating the priority of LungFit BRO, we will be able to maintain our ability to complete the LungFit BRO pivotal study in the second quarter of 2021. Remember, the LungFit BRO pivotal study must be completed in 1 winter season. If we were to delay the IDE submission by just a month, it would mean a 1-year delay in this program.
Further, given the similarities in the systems used for LungFit BRO and LungFit NTM, a delay in bronchiolitis would also mean a delay in NTM. Even just a few months delay in LungFit NTM could be detrimental to our ability to run a high-quality study as it is important to keep up the momentum in NTM.
Now that we have reviewed our priorities, let me go into a bit more detail on the LungFit and then each program. To refresh those of you who have been following us for a while and to bring those of you up to speed who are new to the story, our LungFit system generates Nitric Oxide from ambient air on demand. One system is designed for use with a ventilator, the LungFit PH, to treat PPHN. One is designed for use in the hospital setting with a breathing circuit and mask, the LungFit BRO, to treat bronchiolitis. And one is designed for use in the patient's home with a breathing circuit and mask, the LungFit NTM, to treat NTM and eventually other serious lung infections.
All of our systems require Beyond Air smart filter to operate. There are 2 main reasons for this. First and foremost is safety. Smart filter removes nitrogen dioxide or NO2, which is a toxic byproduct of our process. Thus, operation requires a smart filter to maintain a safe environment for patients and hospital employees as well as family and friends in the home setting. Second reason is the smart filter is our razor blade in the razor-razorblade model. The filter is our main source of revenue, which allows hospitals and payers to pay as needed with minimal capital costs.
Our smart filter is patented separately from our LungFit system. One smart filter lasts 12 hours in the LungFit PH and 40 minutes in the LungFit BRO and LungFit NTM systems.
Now on to our programs. For LungFit PH, we anticipate submitting a PMA in the first quarter of 2020 with the subsequent U.S. launch in the fall of 2020 with our partner, Circassia Pharmaceuticals. We're highly confident that LungFit PH will achieve market leadership in the U.S. and eventually the global market assuming successful development and approval.
The LungFit cylinder-free generator system has several advantages over cylinder-based systems. For example, significantly reducing inventory and storage requirements. No need for purging nitrogen dioxide from the lines, reduction in training burden, overall safety, safer environment for staff and patients and a reduction in cost to the hospital.
Recently, a second player entered the U.S. Nitric Oxide or NO cylinder market. We do not expect any additional competitors for quite some time other than ourselves. The entrance of a second player is fortunate for us as we believe that competition will lead to shorter NO cylinder hospital contracts, enabling switching of hospitals to LungFit in a shorter period of time.
I would like to remind everyone that this market today is worth over $550 million annually in the United States. While we are assuming there will be some price decline associated with the entry of a second competitor, we believe that volume expansion associated with adoption and penetration of the LungFit PH system may more than offset it.
Turning to the LungFit BRO program, we are moving ahead on schedule. Our final pilot study in Israel has seen the first patient dosed, and we anticipate data before midyear 2020. You may recall we have already completed 2 pilot studies and both of them showed about a 24-hour reduction in hospital length of stay, representing a cost savings to the hospital and freeing up bed capacity while also allowing concerned parents to take their child home sooner. Additionally, there were no serious adverse events related to Nitric Oxide therapy.
As a reminder, bronchiolitis is the hospitalization of infants under the age of 2 years due to a viral infection. There are over 125,000 such hospitalizations each year in the United States. Worldwide, it is the #1 cause of infant hospitalizations. Nothing is approved for the treatment of bronchiolitis, and we believe the LungFit BRO will be the first therapeutic approved for treatment of bronchiolitis. This is an important unmet medical need, and we are confident that LungFit BRO can meet this need.
Our pivotal study is slated to begin a year from now and will read out the second quarter of 2021. If we are able to meet this timing and the data are consistent with what we have seen to date, we believe that a 2022 U.S. commercial launch is highly likely.
Now let's turn to LungFit NTM. NTM is the first severe lung infection that we are targeting. We intend to initiate a multi-center, 12-week, self-administered, At-Home pilot study with LungFit NTM in patients with either a Mycobacterium abscessus complex or Mycobacterium avium complex lung infection in the second quarter of calendar 2020. Patients will be titrated up to 250 parts per million nitric oxide. We are confident that this pilot At-Home study will succeed based on the positive results of the data we have generated to date, which includes 13 patients suffering from Mycobacterium abscessus complex and 3 animal studies. Additionally, simplicity of the LungFit NTM for the patient to self-administer is encouraging. Let me describe how the patient will use the system, and then I will touch upon the animal data.
For the patient, it's a simple 5-step process: plug the system into any standard electric outlet; turn on the power switch; insert the smart filter; place the breathing mask on the face; and press the start button. A patient just needs to breathe normally for 40 minutes. The patient falls asleep. There's no need to worry as the system stops generating NO after 40 minutes. The patient will have the ability to pause treatment for a short period of time, if needed. Again, a very simple system to use.
Please recall that LungFit NTM does not work without a Beyond Air smart filter.
With respect to our animal studies, we can point out not only safety but also the performance of the system. All 3 animal studies were performed with the LungFit system. Eight LungFit systems were used in total across 3 studies. The LungFit system logged several hundred hours -- hundreds of hours of delivery time, and NO delivery was consistent, well within any error parameters. Recall that in the 30-day rat study, LungFit systems were used at 400 parts per million nitric oxide, and in both 12-week studies, at 250 parts per million nitric oxide. Hence, we have a very high confidence in the systems performing without incident in the upcoming bronchiolitis and NTM studies, which are using 150 and 250 parts per million NO, respectively.
With respect to safety, I'd like to put things in the proper perspective. In the BRO study that just commenced, our planned pivotal LungFit BRO study, 150 parts per million nitric oxide will be administered 4x per day for 40 minutes for a maximum 5 days. In animal studies, we tested rats for 30 days at 150, 250 and 400 parts per million for the same 160 minutes of exposure per day we will see in the LungFit BRO study. The preclinical dosing in rats was almost 3x the concentration for 30 days versus what will be used in humans for a maximum of 5 days. There were no safety observations at any concentration in the 30-day rat study. Full histopathology was performed in the animals and it is clean, not 1 observation. It is clear that intermittent dosing at high concentrations is safe, and our smart filter is controlling the NO2 exposure.
Comparing this to our LungFit NTM study protocol, we plan on exposing patients to 250 parts per million for 14 days for 160 minutes per day intermittently followed by 250 parts per million for 80 minutes intermittently for 70 days. As I previously mentioned, the highest concentration used in the 30-day rat study was 400 parts per million for 160 minutes exposure per day. This dosing is far in excess of the first 30 days of the planned human NTM study. 12-week rat and dog studies we completed with the LungFit system mimic the human protocol with 250 parts per million nitric oxide we are planning for the LungFit NTM study. 12-week rat study is complete, we are awaiting the histopathology report. And the dog study will be completed in 2 weeks.
So far, neither study has reported any safety observations. In other words, perfectly clean so far. We are quite confident that the LungFit At-Home study in NTM patients will prove to be a success. The pilot study is designed to enroll 20 patients infected with NTM in the lung. Patients can have either refractory Mycobacterium avium complex or Mycobacterium abscessus complex. As I mentioned, the study will be 12 weeks in duration with a look at safety, quality of life, physical function and bacteria load. Earlier this year, the FDA held a public workshop with the emphasis in the conversation of now about improving quality of life and physical function as well as improved safety profile, not necessarily needing eradication of the bacteria to be successful. This change is due to current antibiotic therapies having possible significant and long-lasting adverse effects with little hope of eradication. In the 13 patients treated to date with NO, we have seen these benefits as described by FDA. Further, we've even observed benefits lasting as long as a few months after we stopped NO therapy of just 21 days. Being able to treat safely for 12 weeks at 250 parts per million gives us confidence we can improve patients' lives on multiple parameters and improve on current rates of eradication. I would encourage all of you listening to visit our website for the links to the most recent public discussions on NTM by FDA.
I would like to emphasize that the LungFit At-Home study, NTM study, if successful, opens the door to a very significant market for chronic, severe lung infections treated in the home. NTM is the most difficult-to-treat lung infection we know of. There are data in vitro and in vivo showing that NO can kill other bacteria and viruses more rapidly than NO kills NTM. We look forward to embarking upon a program in COPD patients with severe exacerbations brought on by any pathogen once we obtain the proper resources.
Before I turn it over to Doug to review the financials, I would like to remind everyone that we will be on the exhibit floor at the American Academy of Respiratory Care in New Orleans this weekend with both our LungFit BRO and LungFit PH systems. Additionally, I would like to announce that Beyond Air will be hosting an Analyst Day on March 5, 2020 in New York. We will display our systems, have our Senior Engineer, respiratory therapists, Chief Commercial Officer, Chief Operating Officer, Chief Financial Officer and yours truly, in attendance. Also attending will be KOLs to discuss acute pulmonary hypertension, bronchiolitis and NTM. These are truly exciting times for everyone involved.
Now I will turn the call over to Doug for the financial review. Doug?
