    EMERYVILLE, Calif., Oct. 10, 2021 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (NASDAQ:FDMT), a clinical-stage gene therapy company harnessing the power of directed evolution for targeted gene therapies, announced interim safety and clinical activity data from the Phase 1/2 clinical trial of intravitreal 4D-125 in patients with advanced X-linked retinitis pigmentosa (XLRP). The interim data were presented today in a late-breaking presentation at the American Society of Retina Specialists (ASRS) 39th Annual Meeting.

    "These are the first clinical data reported with a product invented from our Therapeutic Vector Evolution platform at 4DMT, and these interim data demonstrate clinical proof-of-concept for safety, tolerability and clinical activity," said David Kirn, M.D., Co-founder and Chief Executive Officer of 4DMT. "These data support our belief that 4D-125 is well tolerated, and has the potential to both slow the progressive loss of photoreceptors in patients with XLRP after a single intravitreal injection and to improve visual function. We believe these results validate the potential of our platform, and of the R100 vector, which is also deployed in 4DMT targeted product candidates designed to treat a variety of large market diseases. Consistent with our prior guidance, we expect our first R100-based large-market product candidate, 4D-150 for wet AMD, to enter clinical development before year-end."

    "Given the encouraging data we have seen with our intravitreal gene therapy, we plan to continue enrolling patients at the top dose level of 1E12 vg/eye in the dose expansion cohort, including treatment of patients with less advanced disease who are evaluable for both anatomical and functional endpoints," said Dr. Robert Kim, M.D., Senior Vice President & Clinical Therapeutic Area Head, Ophthalmology. "We designed 4D-125 to be administered via intravitreal administration, which targets the entire surface of the retina and thereby enables the potential to treat broader patient populations, including early stage patients, more effectively than is feasible with subretinal approaches. In the case of XLRP, we believe that early stage patient populations may have the potential to benefit from our gene therapy even more than advanced patients given our goal of preserving photoreceptors. We plan to explore development paths that include treating both early stage and advanced patient populations."

    "XLRP is a slowly progressing inherited retinal dystrophy that leads to vision loss and ultimately blindness," said Dr. Cagri Besirli, M.D., Ph.D., University of Michigan, Kellogg Eye Center and a principal investigator on the 4D-125 Phase 1/2 clinical trial. "There are currently no treatment options available to these XLRP patients. 4DMT's gene therapy is a promising approach because, unlike other gene therapy approaches, it is delivered via intravitreal injection, a routine clinical route of administration that targets the entire surface of the retina. These interim clinical data suggest that 4D-125 is well-tolerated and has the potential to both slow the loss of the photoreceptor ellipsoid zone area and enhance retinal sensitivity."

    4D-125 Interim Clinical Data Summary

    The data described are from the first-in-human, on-going Phase 1/2 dose escalation and dose expansion clinical trial assessing intravitreal 4D-125, 4DMT's targeted and evolved R100-based product candidate for XLRP. As of the data cutoff date (September 1, 2021), eight patients with clinically advanced XLRP due to RPGR gene mutation had been enrolled. A standard 3+3 dose escalation design was used, followed by a dose expansion cohort. Patients were enrolled in one of three dose cohorts: dose-escalation cohort 1 (3E11 vg/eye; n=3), dose-escalation cohort 2 (1E12 vg/eye n=3) and the dose expansion cohort (1E12vg/eye; n=2 to date). Patients enrolled in the dose escalation cohorts of the first-in-human clinical trial had clinically-advanced XLRP, with patients having limited or no measurable remaining photoreceptor area or retinal sensitivity. As of the data cutoff date, two dose escalation patients (n=1 at 3E11 vg/eye; n=1 at 1E12 vg/eye) were evaluable for clinical activity defined as having both measurable ellipsoid-zone area (EZ Area) by spectral domain optical coherence tomography (SD-OCT) and retinal sensitivity by microperimetry in both the treated and untreated control eye with at least six months follow-up; dose expansion cohort patients (n=2) had not yet reached six months follow-up but are expected to be evaluable with sufficient follow up. On-going enrollment in the dose expansion cohort is expected to enroll patients with less advanced disease than those enrolled in dose escalation, and who we expect to be evaluable for clinical activity based on central reading center confirmation at screening.

    Interim Safety Data Summary

    • 4D-125 was well-tolerated in all eight XLRP patients, including in five patients at the top dose level of 1E12 vg/eye.
    • No dose-limiting toxicities or serious adverse events were observed.
    • No chronic inflammation was observed.
    • Transient, grade 1+ anterior chamber and/or vitreous cells were observed in two of the eight patients at a single protocol-defined assessment timepoint (SUN1 & NEI2 grading scales)
      • One patient had grade 1+ vitreous and anterior chamber cells
      • One additional patient had grade 1+ vitreous chamber cells

    Interim Clinical Activity Summary

    • In the two dose escalation patients who were evaluable for clinical activity in both the treated and untreated control eyes, interim data from both patients demonstrated anatomical retina preservation as measured by EZ Area progression, a measurement of intact photoreceptors, in the treated eye as compared to the untreated control eye in the same patient. In addition, interim data from both patients demonstrated functional improvements as measured by increases in the mean retinal sensitivity in the treated eye, and a greater number of loci gaining ≥ 7 dB sensitivity in the treated eye, as compared to the untreated control eye in the same patient.

       
      • Patient 3 (3E11 vg/eye cohort – 9 months follow-up): Decreases from baseline EZ Area were -12.4% in the treated eye compared to -16.2% in the untreated control eye (~23% lower relative progression rate). An increase in mean retinal sensitivity was demonstrated, with an increase of +1.65 dB in the treated eye from baseline compared to +0.25 dB in the untreated control eye. The number of loci gaining greater than ≥ 7 dB sensitivity were six in the treated eye compared to one in the untreated control eye.

         
      • Patient 5 (1E12 vg/eye cohort – 6 months follow-up): Decreases from baseline EZ Area were -20.2% in the treated eye compared to -28.7% in the untreated control eye (~30% lower relative progression rate). An increase in mean retinal sensitivity was demonstrated, with an increase of +0.90 dB in the treated eye from baseline compared to +0.10* dB in the untreated control eye. The number of loci gaining greater than ≥ 7 dB sensitivity were three in the treated eye compared to zero in the untreated control eye.             



        *note: microperimetry data for this patient's untreated eye were evaluable at 4 months but not available at month 6 due to an inability to fixate with the untreated control eye at that visit.

  1. EMERYVILLE, Calif., Oct. 06, 2021 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (NASDAQ:FDMT), a clinical-stage gene therapy company harnessing the power of directed evolution for targeted gene therapies, announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug Application (IND) for 4D-150 for wet age-related macular degeneration (wet AMD). The active IND enables the initiation of 4D-150 Phase 1/2 clinical trial sites, which is expected before year-end.

    EMERYVILLE, Calif., Oct. 06, 2021 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (NASDAQ:FDMT), a clinical-stage gene therapy company harnessing the power of directed evolution for targeted gene therapies, announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug Application (IND) for 4D-150 for wet age-related macular degeneration (wet AMD). The active IND enables the initiation of 4D-150 Phase 1/2 clinical trial sites, which is expected before year-end.

    "4D-150 is a dual-transgene intravitreal gene therapy encompassing the R100 capsid which was invented through Therapeutic Vector Evolution with the goal of robust and safe delivery to all regions and major cell types within the retina at relatively low doses," said David Kirn, M.D., Co-Founder and Chief Executive Officer of 4DMT. "We believe that 4D-150's design, which targets four distinct angiogenic factors with dual transgenes, has the potential for broad, robust and durable efficacy after a single low dose intravitreal administration in patients with wet AMD. 4D-150 has the potential to be administered at significantly lower doses compared to other intravitreal AAV gene therapy approaches, and 4D-150 clinical development builds on the favorable tolerability profile to date with the same R100 capsid utilized in our 4D-125 X-linked retinitis pigmentosa (XLRP) program at significantly higher doses. While 4D-125 has been well-tolerated at 1E12 vg/eye, we believe 4D-150 has the potential for clinical activity at substantially lower doses."

    "4D-150 represents numerous firsts in the AAV gene therapy space and underscores 4DMT's commitment to innovation," said Peter Francis, M.D., Ph.D., Chief Scientific Officer. "4D-150 is the first R100-based product candidate to enter clinical development in a large market disease. In addition, it is not only the first clinical-stage dual-transgene AAV gene therapy utilizing an evolved vector, but also the first vectorized RNAi AAV gene therapy product candidate utilizing an evolved vector to enter clinical development."

    The Phase 1/2 clinical trial is a dose-escalation and randomized, controlled, masked expansion trial of intravitreal 4D-150 and is expected to enroll approximately 60 adults with wet AMD. In the dose-escalation phase, multiple dose levels of 4D-150 will be examined in an open-label, 3+3 design with an initial dose of 3E10 vg/eye. In dose expansion, patients (n=50) will be randomized 2:2:1 to receive one of 2 dose levels of 4D-150 (n=20 for each dose level) or aflibercept (n=10). The primary endpoints of the study are safety and tolerability. Secondary endpoints include the number of supplemental aflibercept injections received, and change from baseline in best corrected visual acuity (BCVA) over time.

    About 4D-150 and wet AMD

    4D-150 is a dual-transgene, intravitreal gene therapy designed to inhibit four distinct VEGF factors and prevent angiogenesis and vascular permeability for the treatment of wet AMD. We believe that targeting four distinct angiogenic factors with dual transgenes in patients with these retinal diseases has the potential for greater efficacy and/or lower required doses versus therapies that target a single VEGF factor, including in patients refractory to currently approved anti-VEGF therapies. Intravitreal delivery of biologics to the eye is routine, and a single dose intravitreal gene therapy that could provide long-term efficacy in patients would be an advantage for patients who struggle with treatment burden and/or treatment resistance. 4D-150 builds on the excellent tolerability to date of the R100 capsid in the 4D-125 XLRP clinical program at doses up to 1E12 vg/eye. In the non-human primate retinal laser-induced CNV model data presented in May 2021 at the annual conference of the American Society of Gene and Cell Therapy, at doses ranging from 1E11 to 1E12 vg/eye, 4D-150 intravitreal injection resulted in 100% suppression of grade 4 angiogenic lesions.

    Wet AMD is a type of macular degeneration in which abnormal blood vessels grow into the macula and cause visual distortion, reduced acuity and, in some cases, blindness. The proliferation of abnormal blood vessels in the retina is stimulated by VEGF family members. There are approximately 200,000 new incidences of wet AMD per year in the United States alone. High expression levels of VEGF appear to play a causal role in the symptoms of wet AMD.

  2.

    EMERYVILLE, Calif., Oct. 06, 2021 (GLOBE NEWSWIRE) -- 4D Molecular Therapeutics (NASDAQ:FDMT), a clinical-stage gene therapy company harnessing the power of directed evolution for targeted gene therapies, announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug Application (IND) for 4D-710 for the treatment of patients with cystic fibrosis. The active IND enables the initiation of 4D-710 Phase 1/2 clinical study sites, which is expected before year-end.

    "4D-710 is an aerosol-delivered gene therapy that has promise as a mutation agnostic treatment for patients with cystic fibrosis lung disease," said David Kirn, M.D., Co-Founder and Chief Executive Officer of 4DMT. "4D-710 is designed to express high levels of the cystic fibrosis transmembrane conductance regulator (CFTR) protein directly within target cells lining the airway, enabling CFTR mutation-independent activity, and was also invented for resistance to pre-existing antibodies in humans. We plan to focus initially on the approximately 10-15% of all patients whose disease is not amenable to existing modulator medicines that target the CFTR protein. Ultimately, we believe 4D-710 has the potential to treat a broad cystic fibrosis patient population, including those patients treated with current CFTR modulators, all of which require daily dosing over the patient's lifetime and generally result in only partial correction of lung function."

    "4D-710 is comprised of our targeted and evolved vector, A101, and a microCFTR transgene," said Robert Fishman, M.D., Chief Medical Officer of 4DMT. "A101 was invented not only for aerosol delivery diffusely throughout the lung airways and alveoli, but also for penetration through the mucus barrier and for resistance to pre-existing antibodies, both of which are potentially key attributes for successful treatment of these patients. 4D-710 has the potential to be a differentiated therapy for the treatment of cystic fibrosis lung disease due to its potentially corrective mechanism, expected ability to treat patients independent of CFTR mutation and resistance to AAV antibodies."

    The Phase 1/2 clinical trial is a multicenter, open-label, dose-escalation and dose-expansion trial of 4D-710 in patients (n=~18) with cystic fibrosis who are ineligible for CFTR modulator therapy or who have discontinued therapy due to adverse effects. The primary endpoint of the study is safety and tolerability. Secondary endpoints include assessments of clinical activity including lung function, plus transgene transfer and microCFTR expression as measured within bronchoscopic biopsies and brushings.

    As a result of the IND clearance for 4D-710 and in accordance with the terms of our collaboration with the CF Foundation, CF Foundation will purchase 125,715 shares of our common stock, for aggregate proceeds of approximately $4 million. The proceeds of the CF Foundation equity investment will be used to further support development of 4D-710.

    About 4D-710 and Cystic Fibrosis

    4D-710 is comprised of our targeted and evolved vector, A101, and a codon-optimized microCFTR transgene. 4D-710 has the potential to treat a broad range of patients with cystic fibrosis lung disease, independent of the specific CFTR mutation, and is designed for efficient aerosol delivery to achieve CFTR expression within lung airway epithelial cells. 4D-710 is being initially developed in the approximately 10-15% of patients whose disease is not amenable to existing medicines targeting the CFTR protein. In patients with CFTR mutations whose disease is amenable to modulator medicines, these modulators do not fully restore normal lung function in most patients. Further, these chronic therapies require daily dosing for the patient's lifetime. We therefore expect to eventually develop 4D-710 in this broader patient population, as a single agent and/or in combination with these CFTR modulator small molecule medicines.

    Cystic fibrosis is the most common life-shortening inherited disease in the United States and results from mutations in the CFTR gene. Cystic fibrosis causes impaired lung function, inflammation and bronchiectasis and is commonly associated with persistent lung infections and repeated exacerbations due to the inability to clear thickened mucus from the lungs. These complications result in progressive loss of lung function and hospitalizations, and ultimately lead to end-stage respiratory failure. According to the CF Foundation, more than 30,000 people in the United States and more than 70,000 people worldwide are living with cystic fibrosis, with approximately 1,000 new cases of cystic fibrosis diagnosed in the United States each year. Patients with cystic fibrosis require lifelong treatment with multiple daily medications. Those with end-stage lung disease may undergo lung transplantation.

    About the 4D-125 Phase 1/2 Clinical Trial

    4DMT is currently enrolling patients in an on-going Phase 1/2 dose-escalation and dose-expansion clinical trial assessing intravitreal 4D-125, 4DMT's targeted and evolved R100-based product candidate for XLRP. The study employs a standard 3+3 dose-escalation design, followed by dose expansion. Patients are enrolled in one of two dose cohorts: 3E11 vg/eye and 1E12 vg/eye. The dose expansion phase of the study is enrolling patients at the 1E12 vg/eye dose. The primary objectives of this trial are to evaluate the safety and maximum tolerated dose of 4D-125. Secondary endpoints include assessments of clinical activity, including both visual field function and anatomical endpoints.

    About XLRP

    XLRP is a rare inherited X-linked recessive genetic disorder that causes progressive vision loss and blindness in boys and young men. There are currently no approved therapies for XLRP. Seventy percent of cases are caused by mutations in the retinitis pigmentosa GTPase regulator ("RPGR") gene. The estimated worldwide prevalence of XLRP due to RPGR variants is approximately one in 25,600 people, which represents approximately 24,000 patients in the United States, and France, Germany, Italy, Spain and the United Kingdom (together, EU-5). It is characterized by dysfunction and degeneration of photoreceptors in the retina. Symptoms of XLRP are initially characterized by night blindness, followed by loss of peripheral visual field, decreasing visual acuity and eventually blindness.
