"The second quarter generated strong momentum for Lisata as we continued to advance multiple ongoing and planned clinical studies centered around our novel investigational product, certepetide," stated David J. Mazzo, Ph.D., President and Chief Executive Officer of Lisata. "We have a lot to look forward to with multiple key data readouts projected over the next 18 months, including topline results from the Phase 2b ASCEND trial. These results have transformative potential for the Company as we plan to explore conditional approvals with various regulatory agencies and/or to design an optimized Phase 3 program in metastatic pancreatic ductal adenocarcinoma, an aggressive, often fatal, form of pancreatic cancer. In just the first half of 2024, certepetide has received U.S. FDA Orphan Drug and Rare Pediatric Disease designation in osteosarcoma, and a waiver for evaluating certepetide in a pediatric population with pancreatic cancer in Europe (EMA). These agency recognitions further validate and support our excitement and the broad therapeutic potential of this innovative therapy."

Dr. Mazzo added, "Our continued prudent, strategic financial management allows us to reaffirm our projection that available cash will fund current operations into early 2026, providing the necessary capital for all planned trials through to completion."

Development Portfolio Highlights

Certepetide as a treatment for solid tumors in combination with other anti-cancer agents

Certepetide (formerly LSTA1) is an investigational drug designed to activate a novel uptake pathway that allows co-administered or tethered anti-cancer drugs to penetrate solid tumors more effectively. Certepetide actuates this active transport system in a tumor-specific manner, resulting in systemically co-administered anti-cancer drugs more efficiently penetrating and accumulating in the tumor. Certepetide has also been shown to modify the tumor microenvironment, diminishing its immunosuppressive nature and inhibiting the metastatic cascade. Along with our collaborators, we have amassed significant non-clinical data demonstrating enhanced delivery of various existing and emerging anti-cancer therapies, including immunotherapies and RNA-based therapeutics. To date, certepetide has also demonstrated favorable safety, tolerability, and clinical activity in completed and ongoing clinical trials designed to test its ability to enhance the effectiveness of standard-of-care ("SoC") chemotherapy for pancreatic cancer. Lisata is exploring the potential of certepetide to enable a variety of treatment modalities to treat a range of solid tumors more effectively. Certepetide has been awarded Fast Track designation (U.S.) and Orphan Drug Designation for pancreatic cancer (U.S. and E.U.) as well as Orphan Drug Designation for glioma (U.S.) and osteosarcoma (U.S.). Additionally, certepetide has received Rare Pediatric Disease Designation for osteosarcoma (U.S.). Currently, certepetide is the subject of multiple ongoing or planned Phase 2a and 2b clinical studies being conducted globally in a variety of solid tumor types in combination with a variety of anti-cancer regimens, including:

•ASCEND: Phase 2b double-blind, randomized, placebo-controlled clinical trial evaluating two dosing regimens of certepetide in combination with SoC chemotherapy (gemcitabine/nab-paclitaxel) in patients with metastatic pancreatic ductal adenocarcinoma ("mPDAC"). Cohort A of the study receives a single dose of 3.2 mg/kg certepetide essentially simultaneously with SoC, while Cohort B is identical to Cohort A, but with a second dose of 3.2mg/kg of certepetide given four hours after the first. The trial is being conducted at 25 sites in Australia and New Zealand led by the Australasian Gastro-Intestinal Trials Group in collaboration with the University of Sydney and with the National Health and Medical Research Council Clinical Trial Centre at the University of Sydney as the Coordinating Centre. The conclusion of a planned interim futility analysis in 2023 by the Independent Data Safety Monitoring Committee was that the conditions for futility were not met and that the study should proceed to completion. With trial enrollment completed in the fourth quarter of 2023, Lisata expects topline data from the 95 patients assigned to Cohort A of the study to be reported in the fourth quarter of 2024 and the complete data set of all 158 patients from the study to be available by mid-2025.

•BOLSTER: Phase 2a double-blind, placebo-controlled, multi-center, randomized trial in the U.S. evaluating certepetide in combination with SoC in first- and second-line cholangiocarcinoma ("CCA"). The Company achieved complete enrollment in first-line CCA nearly six months ahead of plan, accelerating anticipated topline data readout to mid-2025. Based on this rapid enrollment rate and the pressing need to improve treatment outcomes in patients that have progressed after first-line CCA treatment, a second cohort has been added to the BOLSTER trial evaluating subjects in second-line CCA. Lisata expects to enroll the first patient by the fourth quarter of 2024.
•CENDIFOX: Phase 1b/2a open-label trial in the U.S. of certepetide in combination with neoadjuvant FOLFIRINOX based therapies in pancreatic, colon and appendiceal cancers. The trial has completed enrollment in the pancreatic cohort and expects to complete enrollment in the remaining two cohorts by the end of 2024.
•Qilu Pharmaceutical, the licensee of certepetide in the Greater China territory, is currently evaluating certepetide in combination with gemcitabine and nab-paclitaxel as a treatment for mPDAC. During the 2023 ASCO (Free ASCO Whitepaper) Annual Meeting, Qilu Pharmaceutical presented an abstract sharing preliminary data from the study which corroborated previously reported findings from the Phase 1b/2a trial of certepetide plus gemcitabine and nab-paclitaxel conducted in Australia in patients with mPDAC. As previously reported, Qilu has begun treating patients in their Phase 2 placebo-controlled trial in mPDAC.
•iLSTA: Phase 1b/2a randomized, single-blind, single-center, safety and pharmacodynamic trial in Australia evaluating certepetide in combination with the checkpoint inhibitor, durvalumab, plus SoC gemcitabine and nab-paclitaxel chemotherapy versus SoC alone in patients with locally advanced non-resectable PDAC. Enrollment completion is expected in the second half of 2024.

•A Lisata-funded Phase 2a, double-blind, placebo-controlled, randomized, proof-of-concept study evaluating certepetide in combination with SoC temozolomide versus temozolomide alone in patients with newly diagnosed GBM is being conducted across multiple sites in Estonia and Latvia and is targeted to enroll 30 patients with a randomization of 2:1 in favor of the certepetide treatment group.

•FORTIFIDE: Phase 1b/2a, double-blind, placebo-controlled, three-arm, randomized study in the U.S. to evaluate the safety, tolerability, and efficacy of a 4-hour continuous infusion of certepetide in combination with SoC in subjects with second-line mPDAC who have progressed on FOLFIRINOX. As part of this study, Lisata has engaged Haystack Oncology to use its MRD technology to measure circulating tumor DNA levels at multiple timepoints in patients throughout the study as an exploratory endpoint for analyzing the early therapeutic effect of certepetide. The Company expects to enroll the first patient in the study by the first half of 2025.

Second Quarter 2024 Financial Highlights

For the three months ended June 30, 2024, operating expenses totaled $5.5 million, compared to $6.9 million for the three months ended June 30, 2023, representing a decrease of $1.4 million or 19.7%.
Research and development expenses were approximately $2.6 million for the three months ended June 30, 2024, compared to $3.2 million for the three months ended June 30, 2023, representing a decrease of $0.6 million or 17.7%. This was primarily due to a reduction in expenses associated with the Phase 2b ASCEND trial which completed enrollment in the prior year, lower spend on chemistry, manufacturing and control ("CMC") related expenses and lower equity expense partially offset by an increase in expenses associated with our enrollment activities in the current year for our BOLSTER trial.
General and administrative expenses were approximately $2.9 million for the three months ended June 30, 2024, compared to $3.7 million for the three months ended June 30, 2023, representing a decrease of $0.8 million or 21.3%. This was primarily due to one-off related severance costs in the prior year associated with the elimination of the Chief Business Officer position on May 1, 2023, a reduction in equity expense and a decrease in directors and officers insurance premiums in the current year.
Benefit from income taxes was $0.0 million for the three months ended June 30, 2024, compared to $2.3 million for the three months ended June 30, 2023. In April 2023, we received net proceeds of $2.2 million from the sale of tax benefits to a qualified and approved buyer pursuant to the New Jersey Economic Development Authority’s Technology Business Tax Certificate Transfer Program.
Overall, net losses were $5.0 million for the three months ended June 30, 2024, compared to $4.0 million for the three months ended June 30, 2023.

Balance Sheet Highlights

As of June 30, 2024, Lisata had cash, cash equivalents, and marketable securities of approximately $38.3 million. Based on its current expected capital needs, the Company believes that its projected capital will fund its current proposed operations into early 2026, encompassing anticipated data milestones from all its ongoing and planned clinical trials.

"Building on the recent BLA acceptance with Priority Review for tab-cel, we are making significant progress with the agency towards the target action date of January 15, 2025, while supporting our partner Pierre Fabre with their U.S. launch preparation," said Pascal Touchon, President and Chief Executive Officer of Atara. "During the quarter we continued to advance the clinical development of our lead CAR T program, ATA3219, and remain on track to deliver key value creating milestones within the next 12 months. This is highlighted by initial data from our non-Hodgkin’s lymphoma study anticipated in the first quarter of 2025, which we believe will provide a read-through for ATA3219’s potential in autoimmune disease. On that front, we plan to initiate our ATA3219 Systemic Lupus Erythematosus trial in the fourth quarter, including the cohort without lymphodepletion, with initial data expected in mid-2025."

Dr. Touchon continued, "Following the landmark milestone of the world’s first-ever approval of an allogeneic T-cell therapy and with the potential first U.S. approval approaching, we are advancing our differentiated allogeneic CAR-T programs into the clinic. With the Company in a strong position, I have decided to move into the role of Chairman for personal reasons to dedicate more time to my family. I look forward to having a very active and strategic advisory role as board chair and continuing to help Atara create value with the potential tab-cel U.S. approval and initial clinical data with ATA3219. I believe the future of Atara is bright under the leadership of Cokey Nguyen, Ph.D. who will be promoted to the role of President and CEO. Cokey is a visionary leader in the cell therapy field, and our Board of Directors values his deep commitment to our staff and to patients as well as his expertise across the breadth of our business."

"I admire the strong foundation we built under Pascal’s leadership. I am honored to serve as Atara’s CEO at this pivotal time to continue our journey to get tab-cel approved in the U.S. and to unlock the disruptive potential of our allogeneic CAR-T platform," said Cokey Nguyen, Ph.D. "I look forward to working alongside our world-class and innovative teams to rapidly innovate and strive to develop better cell therapy treatment options for patients."

Tabelecleucel (tab-cel or EbvalloTM) for Post-Transplant Lymphoproliferative Disease (PTLD)

●
U.S. Food and Drug Administration (FDA) accepted the filing of Atara’s Biologics License Application (BLA) for tabelecleucel (tab-cel) indicated as monotherapy for treatment of adult and pediatric patients two years of age and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD) who have received at least one prior therapy. For solid organ transplant patients, prior therapy includes chemotherapy unless chemotherapy is inappropriate
●
The BLA has been granted Priority Review with a Prescription Drug User Fee Act (PDUFA) target action date of January 15, 2025
●
The data package for the filing includes pivotal and supportive data covering more than 430 patients treated with tab-cel across multiple life-threatening diseases
●
The BLA submission is supported by the latest pivotal ALLELE study data-cut that demonstrated a statistically significant 48.8% Objective Response Rate (ORR) (p<0.0001) and favorable safety profile consistent with previous analyses
●
Atara received a $20 million milestone payment from Pierre Fabre Laboratories in August 2024, following the acceptance of the tab-cel BLA, with the potential to receive a $60 million milestone payment from Pierre Fabre contingent upon FDA approval of the tab-cel BLA

ATA3219: CD19 Program in Lupus Nephritis (LN)

●
Atara expects to initiate a Phase 1 study of ATA3219 as a monotherapy for the treatment of systemic lupus erythematosus (SLE) with kidney involvement (lupus nephritis [LN]) in Q4 2024 with initial clinical data anticipated in mid-2025
○
The Phase 1 open-label, dose-escalation study is designed to evaluate safety, preliminary efficacy, pharmacokinetics, and biomarkers of a single dose of ATA3219 administered to LN subjects refractory to one or more lines of treatment. Subjects will receive lymphodepletion treatment followed by ATA3219 at a dose of 40, 80, or 160 x 106 CAR+ T cells. Each dose level is designed to enroll 3-6 subjects
●
Atara is positioned to potentially expand ATA3219 Phase 1 study into additional autoimmune indications via the same Investigational New Drug (IND) application previously cleared for the LN study
●
Preclinical data supporting the potential of ATA3219 in SLE was presented in poster presentation at the International Society for Cell & Gene Therapy meeting. The data demonstrated that ATA3219 CAR T cells led to complete CD19-specific B-cell depletion against SLE or multiple sclerosis patient peripheral blood mononuclear cells
●
Additional preclinical data presented in the poster showed that ATA3219 CAR T cells, which incorporate the next-generation 1XX costimulatory domain, released lower levels of pro-inflammatory cytokines while maintaining cytotoxic function and potency in response to stimulation with CD19+ target cells when compared to autologous CAR T controls. Mitigating inflammatory cytokine release that is typically seen with standard CD19 CAR T signaling may lead to reduced toxicity and better tolerability if confirmed in clinical trials

ATA3219: CD19 Program in Severe Systemic Lupus Erythematosus (SLE) Without Lymphodepletion

•
Atara plans to expand the Phase 1 LN study of ATA3219 and add a new cohort in severe SLE without lymphodepletion (LD) in Q4 2024 with initial clinical data anticipated in mid-2025
o
Eligible subjects with severe SLE will receive ATA3219 at a dose of 40, 80, or 240 × 106 CAR+ T cells
•
The elimination of LD is designed to further simplify the treatment regimen and to potentially provide a differentiated safety profile to patients without comprising efficacy which may improve patient access •
There is compelling clinical and scientific rationale supporting the potential to eliminate the need for LD based on the EBV T-cell backbone and unique features of ATA3219, including: 1) low alloreactivity risk and favorable safety in over 600 patients treated without LD, due to T-cell receptor EBV specificity and partial human leukocyte antigen matching; 2) expansion and persistence data without LD correlating to efficacy in patients treated with tab-cel; and 3) the inclusion of clinically validated features into ATA3219 such as the 1XX costimulatory domain and memory phenotype that increase potency and persistence

ATA3219: CD19 Program in Non-Hodgkin’s Lymphoma (NHL)

•
Atara continues opening sites and initiating enrollment of a multi-center, Phase 1 open-label, dose-escalation clinical trial of ATA3219 in NHL, including large B-cell lymphomas, follicular lymphoma, and mantle cell lymphoma, with initial clinical data anticipated in Q1 2025
●
Study designed to evaluate safety, preliminary efficacy, pharmacokinetics, and biomarkers. Subjects will receive LD treatment followed by ATA3219 at a dose of 40, 80, 240, or 480 x 106 CAR+ T cells. Each dose level is designed to enroll 3-6 patients
●
Previously presented preclinical data demonstrated superior in vivo persistence and CD19-specific anti-tumor efficacy compared to an autologous CD19 CAR T benchmark with no observed toxicity or alloreactivity

ATA3431: CD19/CD20 Program for B-Cell Malignancies

•
Preclinical data presented at ASH (Free ASH Whitepaper) 2023 demonstrated early evidence of potent antitumor activity, long-term persistence, and superior tumor growth inhibition compared to an autologous CD19/CD20 CAR T benchmark
•
Dual CD19 and CD20 targeting designed to address CD19 escape and tumor variability and may provide additional efficacy in lymphoma
•
Atara is progressing toward an IND submission in H2 2025

Leadership Updates

•
Effective September 9, 2024:
o
Cokey Nguyen, Ph.D., the Company’s current Chief Scientific and Technical Officer, will be promoted to the role of President and CEO and Pascal Touchon, the Company’s current President and CEO, will transition to the role of Chairman of the Board of Directors

About ATA3219

ATA3219 combines the natural biology of unedited T cells with the benefits of an allogeneic therapy. It consists of allogeneic Epstein-Barr virus (EBV)-sensitized T cells that express a CD19 CAR construct for the treatment of CD19+ relapsed or refractory B-cell malignancies, including B-cell non-Hodgkin’s lymphoma and B-cell mediated autoimmune diseases including systemic lupus erythematosus. ATA3219 has been optimized to offer a potential best-in-class profile, featuring off-the-shelf availability. It incorporates multiple clinically validated technologies including a modified CD3ζ signaling domain (1XX) that optimizes expansion and mitigates exhaustion, enrichment during manufacturing for a less differentiated phenotype for robust expansion and persistence and retains the endogenous T-cell receptor without gene editing as a key survival signal for T cells contributing to persistence.About ATA3431

ATA3431 is an allogeneic, bispecific CAR directed against CD20 and CD19, built on Atara’s EBV T-cell platform. The design consists of a tandem CD20-CD19 design, with binders oriented to optimize potency. Dual targets address the limitations of single antigen loss and tumor variability. ATA3431 features a novel 1XX costimulatory domain, memory phenotype, and retained, unedited T-cell receptor. Preclinical data have demonstrated early evidence of antitumor activity, long-term persistence, and superior tumor growth inhibition compared to an autologous CD19/CD20 CAR T benchmark.

Next-Generation Allogeneic CAR T Approach

Atara is focused on applying Epstein-Barr virus (EBV) T-cell biology, featuring experience in over 600 patients treated with allogeneic EBV T cells, and novel chimeric antigen receptor (CAR) technologies to meet the current limitations of autologous and allogeneic CAR therapies head-on by advancing a potential best-in-class CAR T pipeline in oncology and autoimmune disease. Unlike gene-edited approaches aimed at inactivating T-cell receptor (TCR) function to reduce the risk for graft-vs-host disease, Atara’s allogeneic platform maintains expression of the native EBV TCR that promote in vivo functional persistence while also demonstrating inherently low alloreactivity due to their recognition of defined viral antigens and partial human leukocyte antigen (HLA) matching. A molecular toolkit of clinically-validated technologies—including the 1XX costimulatory domain designed for better cell fitness and less exhaustion while maintaining stemness—offers a differentiated approach to addressing significant unmet need with the next generation CAR T.

"Aprea continues to make excellent progress advancing its clinical pipeline of therapeutic candidates," said Oren Gilad, Ph.D., President and Chief Executive Officer of Aprea. "We initiated enrollment in the ACESOT-1051 trial, advancing a second clinical asset in our pipeline, APR-1051. APR-1051 is a next-generation inhibitor of WEE1 kinase which has been designed to limit toxicity. Based on its unique characteristics, we believe it could be best in class. We continue to enroll patients in the ABOYA-119 trial evaluating ATRN-119, our ATR inhibitor. We believe that our ongoing progress positions Aprea at the forefront of synthetic lethality drug development. We remain committed to developing new treatments that have a positive impact on the lives of cancer patients while creating value for our shareholders."

Key Business Updates and Potential Upcoming Key Milestones

ACESOT-1051: A Biomarkers Focused, Phase 1 Trial of Oral WEE1 inhibitor, APR-1051, initiated

APR-1051 is a potent and selective small molecule that has been designed to potentially solve liabilities and may achieve greater clinical activity than other WEE1 programs currently in development. Aprea is advancing APR-1051 as monotherapy in cancers with Cyclin E over expression, as well as other biomarkers that are predicted to be sensitive to WEE1 inhibition. Cancers overexpressing Cyclin E represent a high unmet medical need. Patients with Cyclin E overexpression have poor prognosis and, currently, have no effective therapies.
In June 2024, enrollment commenced in the ACESOT-1051 (A Multi-Center Evaluation of WEE1 Inhibitor in Patients with Advanced Solid Tumors, APR-1051) Phase 1 clinical trial evaluating single-agent APR-1051 in advanced solid tumors harboring cancer-associated gene alterations. The first patient was dosed at NEXT Oncology, San Antonio, Texas, without any dose-limiting toxicities (including myelosuppression) observed to date in the first cohort. A second patient has been enrolled at The University of Texas MD Anderson Cancer Center and has commenced treatment in the second dose cohort.
The primary objectives of the Phase 1 study are to measure safety, dose-limiting toxicities (DLTs), maximum tolerated dose or maximum administered dose (MTD/MAD), and recommended Phase 2 dose (RP2D); secondary objectives are to evaluate pharmacokinetics, preliminary efficacy according to RECIST or PCWG3 criteria; pharmacodynamics is an exploratory objective.
The Company will provide an update on the progress of this clinical study by year end. Open-label safety/efficacy data are expected in the first half of 2025.
In June 2024, Aprea hosted a virtual KOL event to discuss APR-1051. Joseph Vacca, Ph.D., Medicinal Chemistry Expert and Consultant to Aprea, discussed the medicinal chemistry history, strategy-guided selective drug design, and preclinical findings of APR-1051. Eric J. Brown, Ph.D., University of Pennsylvania and Consultant to Aprea, discussed preclinical findings across the WEE1 inhibitor class. A replay of the event (with slides) can be accessed on Aprea’s corporate website here.
APR-1051 was featured in two posters at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting which took place in April 2024 in San Diego, which summarized the pre-clinical data supporting APR-1051 and the trial design for ACESOT-1051.
ABOYA-119: Ongoing Clinical Trial Evaluating ATR inhibitor, ATRN-119

ATRN-119 is a potent and highly selective first-in-class macrocyclic ATR inhibitor, designed to be used in patients with mutations in DDR-related genes. Cancers with mutations in DDR-related genes represent a high unmet medical need. Patients with DDR-related gene mutations have a poor prognosis and, currently, have no effective therapies.
ATRN-119 is currently being evaluated in the open-label Phase 1/2a clinical trial of ABOYA-119 (study AR-276-01) as monotherapy in patients with advanced solid tumors having at least one mutation in a defined panel of DDR-related genes. The first five dose cohorts (50mg to 550mg once daily) have been completed, and patients continue to enroll in additional cohorts in the dose escalation part of the trial.
The primary endpoint of this Phase 1 trial is the tolerability and pharmacokinetics of ATRN-119 when administered orally on a continuous, once-daily schedule. Aprea is planning to amend the study protocol to add a group of patients who will receive ATRN-119 twice a day and to investigate the effect of food on ATRN-119 absorption and drug exposure in blood. Under the current protocol, the Company anticipates the ABOYA-119 Phase 1 readout to be available in the first half of 2025.
An update on the ongoing trial was featured in a poster at the AACR (Free AACR Whitepaper) Annual Meeting this past April. A copy of the AACR (Free AACR Whitepaper) poster can be found here.

As of June 30, 2024, the Company reported cash and cash equivalents of $28.7 million, compared to $21.6 million at December 31, 2023. The Company believes its cash and cash equivalents as of June 30, 2024, will be sufficient to meet its currently projected operating expenses and capital expenditure requirements into the fourth quarter of 2025.
For the quarter ended June 30, 2024, the Company reported an operating loss of $3.8 million, compared to an operating loss of $3.7 million in the comparable period in 2023.
Grant revenue, primarily from the National Cancer Institute of the National Institutes of Health ("NIH") for the three months ended June 30, 2024, and 2023 was approximately $0.6 million and $0.2 million, respectively.
Research and development expenses were approximately $2.6 million for the quarter ended June 30, 2024, compared to approximately $2.2 million for the comparable period in 2023. The increase was primarily due to an increase in expenses related to the initiation of ACESOT-1051, our Phase 1 dose-escalation study evaluating APR-1051, our small molecule WEE1 inhibitor, in the second quarter of 2024.
General and administrative expenses were approximately $1.9 million for the quarter ended June 30, 2024, compared to approximately $1.7 million for the comparable period in 2023. The increase was primarily related to an increase in personnel costs primarily related to severance expense.
The Company reported a net loss of $3.5 million ($0.58 per basic share) on approximately 5.9 million weighted-average common shares outstanding for the quarter ended June 30, 2024, compared to a net loss of $3.3 million ($0.87 per basic share) on approximately 3.7 million weighted average common shares outstanding for the comparable period in 2023.

Adrian Rawcliffe, Adaptimmune’s Chief Executive Officer: "On 1 August, we received US FDA approval for Tecelra, the first ever engineered cell therapy for a solid tumor and the first new treatment option for people with synovial sarcoma in more than a decade. We have hit the ground running to make Tecelra available to eligible patients. Patients can start their treatment journey now with healthcare providers able to begin testing and our ordering platform is up and running. Tecelra will be available in 6-10 US authorized treatment centers in the coming weeks. Tecelra is the first product in our sarcoma franchise, and we are planning to commence our rolling BLA submission for lete-cel in 2025 and commercial launch in 2026. We expect our sarcoma franchise to redefine the treatment landscape in advanced soft tissue sarcoma with projected peak US sales of $400 million."

Sarcoma Franchise with Tecelra and lete-cel

● U.S. Food and Drug Administration (FDA) approves Tecelra for the treatment of advanced MAGE-A4+ synovial sarcoma in adults with certain HLA types who have received prior chemotherapy.
● Tecelra is the first engineered cell therapy for solid tumors.
● Tecelra is the first new treatment option for synovial sarcoma in more than a decade.
● Tecelra is a single infusion treatment.
● No Risk Evaluation and Mitigation Strategies (REMS) program was required for BLA approval.
● Patients can start their treatment journey now, with testing approved and available in the United States.
● Sarcoma centers of excellence across the Unites States are being onboarded as Authorized Treatment Centers (ATCs) for Tecelra.
● The approval of Tecelra was based on results of the SPEARHEAD-1 (Cohort 1) trial. The major efficacy outcome was overall response rate (ORR) by independent review and supported by duration of response. Tecelra treatment resulted in an ORR of 43% with a complete response rate of 4.5%. The median duration of response was 6 months (95% CI: 4.6, not reached). Among patients who were responsive to the treatment, 39.0% had a duration of response of 12 months or longer. Data from the pivotal SPEARHEAD-1 trial were previously published in The Lancet earlier this year.

● Data presentations:
o Data from the pivotal IGNYTE-ESO trial of lete-cel (letetresgene autoleucel), an engineered cell therapy targeting NY-ESO-1, in synovial sarcoma (SyS) and myxoid/round cell liposarcoma (MRCLS) was presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper)’s (ASCO) (Free ASCO Whitepaper) annual meeting. The overall response rate (ORR) of 40% was consistent across both SyS and MRCLS, meeting the primary endpoint success criterion for efficacy. Given the trial’s success, Adaptimmune plans to initiate a rolling Biologics License Application (BLA) submission for lete-cel for the treatment of advanced or metastatic MRCLS and synovial sarcoma during 2025. Lete-cel will bolster Adaptimmune’s sarcoma franchise by expanding the addressable patient population to NY-ESO-1 positive MRCLS and SyS solid tumors.
Clinical pipeline

● Adaptimmune recently announced the company had entered into a clinical collaboration agreement with Galapagos to conduct a clinical proof-of-concept trial to evaluate the safety and efficacy of uza-cel (next-generation engineered TCR T-cell therapy, formerly ADP-A2M4CD8) using Galapagos’ decentralized manufacturing platform in patients with head & neck cancer and potential future solid tumor cancer indications.
● Adaptimmune retains the right to develop, manufacture, commercialize, and otherwise exploit uza-cel for platinum-resistant ovarian cancer.
● Uza-cel is being investigated in the SURPASS-3 Phase 2 clinical trial (NCT05601752) for the treatment of platinum-resistant ovarian cancer. Uza-cel received FDA RMAT designation in 2022 for the treatment of patients with platinum resistant ovarian cancer. The SURPASS-3 trial is currently enrolling patients.
● Screening in the SURPASS Phase 1 trial has stopped and enrolment will cease shortly.

Preclinical pipeline

● Wholly owned allogeneic pipeline progressing; process optimization continues at Adaptimmune’s facility in Milton Park, UK.
● IND-enabling activities continue for ADP-600 (PRAME) and ADP-520 (CD70) programs.

Business and corporate updates

● Under the terms of Adaptimmune and Galapagos’ collaboration agreement, Adaptimmune will receive initial payments of $100 million, comprising $70 million upfront and $30 million of R&D funding of which $15m was received on signing, option exercise fees of up to $100 million, additional development and sales milestone payments of up to a maximum of $465 million, plus tiered royalties on net sales.
● Adaptimmune announced in May entry into a Loan and Security Agreement with Hercules Capital, Inc., for a term loan facility of up to $125.0 million. Following the receipt of FDA approval for Tecelra, the Company is eligible to draw down the Tranche 2 Advance of $25.0 million and is in the process of requesting this Tranche 2 Advance.

Financial Results for the three and six months ended June 30, 2024

● Cash / liquidity position: As of June 30, 2024, Adaptimmune had cash and cash equivalents of $211.8 million and Total Liquidity2 of $214.8 million, compared to $144.0 million and $146.9 million respectively, as of December 31, 2023.
● Revenue: Revenue for the three and six months ended June 30, 2024, was $128.2 million and $133.9 million, respectively, compared to $5.1 million and $52.7 million for the same periods in 2023. Revenue has increased in 2024, compared to the same periods in 2023 primarily due to the termination of the Genentech collaboration in the second quarter of 2023, resulting in the majority of the remaining deferred income for the collaboration being recognized as revenue including a cumulative catch-up adjustment of $101.3 million. This was significantly higher than the impact from the termination of the Astellas collaboration in 2023, which resulted in $42.4 million of revenue being recognized in March 2023.
● Research and development (R&D) expenses: R&D expenses for the three and six months ended June 30, 2024, were $40.4 million and $75.7 million, respectively, compared to $30.0 million and $55.5 million for the same periods in 2023. R&D expenses increase due to an increase in the average number of employees engaged in research and development, increases in subcontracted expenditures, an increase in in-process research and development costs and a decrease in offsetting reimbursements receivable for research and development tax and expenditure credits.
● General and administrative (G&A) expenses: G&A expenses for the three and six months ended June 30, 2024, were $19.1 million and $38.8 million, respectively, compared to $20.1 million and $40.5 million for the same periods in 2023. G&A expenses decreased due to restructuring and charges recognised in the first quarter of 2023 that were not repeated in 2024 and an increase in offsetting reimbursements, offset by an increase in other corporate costs due to an increase in accounting, legal and professional fees in the second quarter of 2024 due to fees relating to business development work and preparation for commercialization.
● Net profit/(loss): Net profit attributable to holders of the Company’s ordinary shares for the three and six months ended June 30, 2024, was $69.5 million and $21.0 million, respectively ($0.05 and $0.01 per ordinary share), compared to losses of $21.3 million and $20.4 million ($(0.02) and $(0.02) per ordinary share), for the same periods in 2023.

"Having completed data generation for nearly all of the Chemistry Manufacturing and Controls deliverables outlined in the Complete Response Letter that we received in April 2024, we are on track to resubmit our Biologics License Application for pz-cel this year and, if approved, bring a treatment option to patients with recessive dystrophic epidermolysis bullosa," said Vish Seshadri, Chief Executive Officer of Abeona.

Second Quarter and Recent Progress

Pz-cel for RDEB

● On August 8, 2024, Abeona completed a Type A meeting with the U.S. Food and Drug Administration (FDA) to discuss Abeona’s forthcoming resubmission of its Biologics License Application (BLA) for prademagene zamikeracel (pz-cel), its investigational first-in-class, autologous cell-based gene therapy currently in development for recessive dystrophic epidermolysis bullosa (RDEB). In pre-meeting communications and during the Type A meeting, Abeona shared data and reports addressing nearly all of the deficiencies noted in the Complete Response Letter (CRL) and gained the FDA’s preliminary alignment pending formal review. For two remaining outstanding items related to sterility assays and identity assays, validation is currently ongoing under protocols that incorporate FDA feedback. Abeona continues to expect to resubmit the BLA in the second half of 2024. Upon acceptance of the BLA, Abeona expects the FDA to set a Prescription Drug User Fee Act (PDUFA) action date six months from the date of submission.

● In April 2024, Abeona received a CRL from the FDA based on the need for additional Chemistry Manufacturing and Controls (CMC) information. In the CRL, the FDA noted that certain additional information needed to satisfy CMC requirements must be resolved before the application can be approved. The CRL did not identify any deficiencies related to the clinical efficacy or clinical safety data in the BLA, and the FDA did not request any new clinical trials or clinical data to support the approval of pz-cel.

● In May 2024, new pz-cel long-term safety data with up to 11 years of follow-up were presented during a late-breaker session at the Society for Investigative Dermatology (SID) Annual Meeting. In July 2024, data on wound healing at various anatomical sites after pz-cel treatment were presented at the Society for Pediatric Dermatology (SPD) Annual Meeting.

U.S. commercial launch preparations for pz-cel

● Abeona continues to make progress on key commercial activities in preparation for a potential U.S. launch for pz-cel, including onboarding discussions with epidermolysis bullosa treatment sites, conducting medical and payer engagement, and building supply chain and enterprise capabilities to support the Company’s transition to a commercial stage company.

Pipeline programs

● In July 2024, Abeona announced a non-exclusive agreement with Beacon Therapeutics, under which Beacon Therapeutics will evaluate Abeona’s patented AAV204 capsid for its potential use in AAV gene therapies for select ophthalmology indications.

Corporate highlights

● In May 2024, Abeona closed a $75 million underwritten securities offering with participation from both new and existing investors.

Second Quarter Financial Results and Cash Runway Guidance

Cash, cash equivalents, short-term investments and restricted cash totaled $123.0 million as of June 30, 2024. As of March 31, 2024, cash, cash equivalents, short-term investments and restricted cash totaled $62.7 million. Net cash used in operating activities was $12.7 million for the three months ended June 30, 2024.

Abeona estimates that its current cash and cash equivalents, short-term investments and restricted cash, as well as its $50 million credit facility, are sufficient resources to fund operations into 2026, before accounting for any potential revenue from commercial sales of pz-cel, if approved, or proceeds from the sale of a Priority Review Voucher (PRV), if awarded by the FDA.

Research and development expenses for the three months ended June 30, 2024 were $9.2 million, compared to $8.5 million for the same period of 2023. General and administrative expenses were $8.6 million for the three months ended June 30, 2024, compared to $5.0 million for the same period of 2023. The increase in general and administrative expenses is primarily due to commercial and launch preparation costs. Net income for the second quarter of 2024 was $7.4 million, including a $24.9 million gain resulting from the quarterly remeasurement of the fair value of warrant liabilities. In the second quarter of 2023, net loss was $16.7 million, including an $8.6 million loss resulting from the quarterly remeasurement of the fair value of warrant liabilities.
