Insights
The recent announcement by TFF Pharmaceuticals regarding positive Phase 2 trial outcomes for TFF VORI and TFF TAC could be a pivotal moment for the company and its investors. The data indicating efficacy and safety in treating invasive pulmonary aspergillosis (IPA) and preventing rejection after lung transplantation addresses a significant gap in current treatment options. The ability to maintain kidney function while reducing tacrolimus blood levels is particularly noteworthy, as it may lead to improved patient outcomes and potentially lower healthcare costs associated with long-term kidney damage.
Investors should monitor the progress of the upcoming registration-enabling studies, as successful outcomes could significantly enhance the company's valuation. Additionally, the proprietary Thin Film Freezing (TFF) technology platform may offer a competitive edge in drug delivery, potentially opening avenues for licensing deals or partnerships, which could diversify revenue streams beyond the company's current pipeline.
The data presented by TFF Pharmaceuticals suggests a favorable comparison to the standard-of-care, oral voriconazole, especially in terms of safety and tolerability. This is particularly significant for patients with chronic lung allograft dysfunction (CLAD), where the standard treatment can exacerbate their condition. The lack of severe adverse events and the successful transition from oral tacrolimus to TFF TAC without signs of acute rejection are promising indicators for the potential improvement in the quality of life of lung transplant patients.
Long-term follow-up data will be critical to understanding the durability of these responses and the potential for widespread adoption. If the long-term data remains positive, this could lead to a reevaluation of current treatment protocols and potentially establish TFF Pharmaceuticals' treatments as new standards in their respective indications.
The strategic decision to accelerate the development of TFF VORI and TFF TAC into registration-enabling studies reflects management's confidence in the clinical data. This move could shorten the time to market and may attract investor interest due to the potential for earlier revenue generation. However, it's important for investors to consider the inherent risks associated with clinical development, including the possibility of future trial failures, regulatory setbacks, or challenges in commercialization.
Given the treatments' focus on rare diseases with high unmet medical needs, there could be opportunities for orphan drug designation, which provides benefits such as market exclusivity, tax credits and waiver of certain regulatory fees. This could enhance the financial outlook for the company and provide additional incentives for investors. Stakeholders should also consider the broader market dynamics, including competitor activities and the evolving landscape of treatment options for IPA and post-lung transplantation care.
Treatment with TFF VORI resulted in positive treatment outcomes based on clinical, mycologic and radiologic responses while maintaining a favorable safety/tolerability profile, with no all-cause mortality, no invasive pulmonary aspergillosis (IPA)-related mortality, and no TFF VORI discontinuations due to an adverse event (AE)
Successful transition of all four patients from oral tacrolimus to TFF TAC, leading to significant lowering of tacrolimus blood levels with no clinical evidence of acute rejection; all patients who completed Part A (study treatment period) of the trial chose to remain on TFF TAC and advance to Part B (extension study)
TFF TAC was well tolerated, with no mortality and no TFF TAC discontinuations due to an AE; kidney function was maintained in all patients treated with TFF TAC
Based on the promising Phase 2 data for both products, the Company plans to accelerate the initiation of registration-enabling studies

FORT WORTH, Texas, Dec. 19, 2023 (GLOBE NEWSWIRE) -- TFF Pharmaceuticals, Inc. (NASDAQ: TFFP), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative drug products based on its patented Thin Film Freezing (TFF) technology platform, today announced positive initial data from the Company’s ongoing Phase 2 trials of TFF VORI and TFF TAC, along with clinical data from the ongoing TFF VORI Expanded Access Program (EAP).
“Today is truly a remarkable moment in the history of TFF Pharmaceuticals, as these initial clinical data clearly demonstrate the efficacy and favorable safety and tolerability of TFF VORI and TFF TAC in two rare disease indications with high unmet medical need. These compelling results also demonstrate the successful clinical application of our ground-breaking technology platform,” said Harlan Weisman, M.D., President and Chief Executive Officer of TFF Pharmaceuticals. “Based on these highly encouraging efficacy and safety data, we have made the decision to accelerate the development of TFF VORI and TFF TAC into registration-enabling studies, given the unequivocally positive results from these initial data. Looking ahead, we expect to present additional clinical data in the first quarter of 2024 to further support the advancement of TFF VORI and TFF TAC into registration-enabling studies.”
“These initial data provide compelling evidence that both TFF VORI and TFF TAC have game-changing potential in the treatment of their respective rare disease indication, IPA and prevention of rejection after lung transplantation,” said Zamaneh Mikhak, M.D., Chief Medical Officer of TFF Pharmaceuticals. “With respect to TFF VORI, the initial data from the Phase 2 trial and our EAP clearly demonstrate a positively differentiated safety and tolerability profile from the standard-of-care, first-line therapy, oral voriconazole, based on the available historical data. The efficacy results are equally remarkable with treatment response seen in all patients. Initial results from the TFF TAC study are also impressive. Patients treated with TFF TAC did not experience clinically acute rejection at significantly reduced blood tacrolimus levels. Additionally, the patients maintained their kidney function and chose to remain on TFF TAC long term.”
TFF VORI - initial Phase 2 and EAP data
The ongoing Phase 2 trial of TFF VORI is an open-label, randomized (3:1) study evaluating treatment with TFF VORI versus oral voriconazole over a 13-week period in patients with IPA. Trial endpoints include safety, tolerability, clinical response, mycologic response, radiologic response, and all-cause mortality. The initial efficacy data presented below include patients from the Phase 2 trial and the Company’s EAP who received at least 8 weeks of therapy with either TFF VORI (N=5) or oral voriconazole (N=1). Safety data included all TFF VORI-treated patients (N=7) and oral voriconazole-treated patients (N=2). Of note, three of the five patients who were treated with TFF VORI for at least 8 weeks had a diagnosis of chronic lung allograft dysfunction (CLAD), which is a lung disease caused by chronic rejection, from the immune system attacking the transplanted lungs. CLAD is a significant cause of morbidity and mortality after lung transplantation and can be exacerbated by infections, further deteriorating the patient’s condition. The patient treated with oral voriconazole for at least 8 weeks did not present with CLAD.
Efficacy
- Of the five patients treated for at least 8 weeks with TFF VORI:
- All five patients achieved a clinical response
- All five patients achieved a mycologic response
- Three of four patients with pre- and post-treatment chest CT achieved a radiologic response
- No need for continued anti-fungal use after treatment with TFF VORI in all five patients
Safety
- No all-cause mortality
- No IPA-related mortality
- No TFF VORI discontinuation due to an AE
