Proceeds from the financing will be used to advance two RIPTAC candidates into clinical trials for patients with prostate cancer and breast cancer, initially in the metastatic setting where drug resistance to standard of care is prevalent. Halda’s lead RIPTAC therapeutic, HLD-0915, is expected to initiate a Phase 1 clinical trial in the first half of 2025 for the treatment of patients with metastatic, castration-resistant prostate cancer (mCRPC). The financing will also support the clinical development of a second RIPTAC therapeutic for metastatic breast cancer. In addition, the funding will enable the company to further build its team and to develop additional products using its RIPTAC platform to address other indications with unmet need.

"We are excited to have the support of this leading group of new healthcare investors who share our vision to be a cancer drug innovator. This financing will enable us to bring to patients our oral, selective, and widely applicable cancer cell-killing mechanism that is designed to overcome drug resistance, which is a major shortcoming of many current standard of care cancer treatments," said Kat Kayser-Bricker, PhD, Chief Scientific Officer of Halda Therapeutics. "Our team of talented scientists has made tremendous progress, from inventing the RIPTAC modality to translating our platform into two promising programs in prostate cancer and breast cancer, with our first drug candidate entering the clinic in the first half of 2025 for mCRPC patients."

The RIPTAC modality, now advancing into clinical trials with this financing, has been designed by Halda as a heterobifunctional molecule that targets two proteins for a novel cancer cell-killing mechanism to address a specific cancer type. RIPTAC therapeutics work by a novel "hold and kill" mechanism, bringing together two proteins – a cancer-specific protein and a protein with essential function – resulting in abrogation of the essential cell function, and subsequently, death of the cancer cells while sparing non-cancer tissue where the cancer-specific protein is absent or minimally expressed.

"Novel mechanisms are desperately needed to address resistance to standard of care therapies across a number of tumor types. RIPTAC therapies offer an ability to selectively kill cancer cells based on differential protein expression in orally bioavailable medicines. This innovation has the potential to treat both advanced cancer patients with heterogeneous resistance adaptations, as well as patients with earlier stages of disease. We look forward to working with Halda scientists and clinicians to deliver novel therapies to improve outcomes for cancer patients," said Joe Cabral, Principal at Frazier Life Sciences.

"The team at Halda is creating a new era for oncology treatment with a groundbreaking modality, RIPTAC therapeutics, including medicines that have the potential to deliver solutions for cancer patients beginning with two of the most prevalent cancer types, prostate cancer and breast cancer. In particular, Halda’s lead RIPTAC candidate, HLD‑0915, offers the potential for a mutation-agnostic small molecule approach in the mCRPC setting to address unmet needs for these prostate cancer patients globally," said Arjun Goyal, MD, Co‑Founder and Managing Director, Vida Ventures.

In conjunction with this financing, Rebecca Luse, Principal at Deep Track Capital, Joe Cabral, Principal at Frazier Life Sciences, Nandita Shangari, PhD, Managing Director at RA Capital Management and Arjun Goyal, MD, Co-Founder and Managing Director at Vida Ventures, will join the Halda Board of Directors.

HARMONi-2 evaluated monotherapy ivonescimab against monotherapy pembrolizumab in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors have positive PD-L1 expression (PD-L1 TPS >1%). HARMONi-2 is a single region, multi-center, double-blinded Phase III study conducted in China sponsored by our collaboration partner, Akeso, Inc. (Akeso, HKEX Code: 9926.HK), with data generated and analyzed by Akeso.

There are no known Phase III clinical trials in NSCLC that have shown a statistically significant efficacy improvement compared to pembrolizumab in a head-to-head setting.

On May 30, 2024, Akeso announced that in HARMONi-2 ivonescimab monotherapy achieved a statistically significant improvement in the trial’s primary endpoint, progression-free survival (PFS), when compared to monotherapy pembrolizumab. The PFS benefit was demonstrated across clinical subgroups, including those with PD-L1 low expression (PD-L1 TPS 1-49%), PD-L1 high expression (PD-L1 TPS ≥50%), squamous and non-squamous histologies, as well as other high-risk patients.

The trial results will be presented by Dr. Caicun Zhou, Chief Physician and Director of the Department of Medical Oncology at Shanghai Pulmonary Hospital, Tongji University School of Medicine, and President-Elect of IASLC.

A second presentation titled, "A Phase II Study of Perioperative Ivonescimab Alone or Combined with Chemotherapy in Resectable Non-Small Cell Lung Cancer" will include data from the Phase II trial, AK112-205, which is conducted and sponsored by Akeso, featuring data from ivonescimab in the perioperative, early-stage NSCLC setting.

About Ivonescimab

Ivonescimab, known as SMT112 in Summit’s license territories, the United States, Canada, Europe, Japan, Latin America, including Mexico and all countries in Central America, South America, and the Caribbean, the Middle East, and Africa, and as AK112 in China and Australia, is a novel, potential first-in-class investigational bispecific antibody combining the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule. Ivonescimab displays unique cooperative binding to each of its intended targets with multifold higher affinity when in the presence of both PD-1 and VEGF.

This could differentiate ivonescimab as there is potentially higher expression (presence) of both PD-1 and VEGF in tumor tissue and the tumor microenvironment (TME) as compared to normal tissue in the body. Ivonescimab’s tetravalent structure (four binding sites) enables higher avidity (accumulated strength of multiple binding interactions) in the tumor microenvironment with over 18-fold increased binding affinity to PD-1 in the presence of VEGF in vitro, and over 4-times increased binding affinity to VEGF in the presence of PD-1 in vitro (Zhong, et al, SITC (Free SITC Whitepaper), 2023). This tetravalent structure, the intentional novel design of the molecule, and bringing these two targets into a single bispecific antibody with cooperative binding qualities have the potential to direct ivonescimab to the tumor tissue versus healthy tissue. The intent of this design, together with a half-life of 6 to 7 days (Zhong, et. al., SITC (Free SITC Whitepaper), 2023), is to improve upon previously established efficacy thresholds, as well as to improve upon side effects and safety profiles associated with these targets.

Ivonescimab was engineered by Akeso Inc. (HKEX Code: 9926.HK) and is currently engaged in multiple Phase III clinical trials. Over 1,800 patients have been treated with ivonescimab in clinical studies globally.

Summit has begun its clinical development of ivonescimab in non-small cell lung cancer (NSCLC), commencing enrollment in 2023 in two multi-regional Phase III clinical trials, HARMONi and HARMONi-3.

HARMONi is a Phase III clinical trial which intends to evaluate ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with a 3rd generation EGFR TKI (e.g., osimertinib).

HARMONi-3 is a Phase III clinical trial which is designed to evaluate ivonescimab combined with chemotherapy compared to pembrolizumab combined with chemotherapy in patients with first-line metastatic squamous NSCLC.

In addition, Akeso has recently had positive read-outs in two single-region (China), randomized Phase III clinical trials for ivonescimab in NSCLC, HARMONi-A and HARMONi-2.

HARMONi-A was a Phase III clinical trial which evaluated ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with an EGFR TKI.

HARMONi-2 is a Phase III clinical trial evaluating monotherapy ivonescimab against monotherapy pembrolizumab in patients with locally advanced or metastatic NSCLC whose tumors have positive PD-L1 expression (PD-L1 TPS >1%).

Ivonescimab is an investigational therapy that is not approved by any regulatory authority in Summit’s license territories, including the United States and Europe. Ivonescimab was approved for marketing authorization in China in May 2024.

"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.

"Our team continues to make solid progress towards the Company’s ambitious R&D objectives that we established for 2024 and beyond. We are focused on advancing our two lead clinical programs, including the first-in-class, highly selective SMARCA2 degrader, PRT3789 and a potent and selective CDK9 inhibitor, PRT2527, both on track to report initial clinical results this year," stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude.

Dr. Vaddi continued, "We believe that targeting the SMARCA pathway has the potential to deliver a ‘pipeline in a program.’ We are building on our leadership position by advancing the industry’s first highly selective oral SMARCA2 degrader, PRT7732, into the clinic, and will initiate a study of PRT3789 in combination with KEYTRUDA in collaboration with Merck later this year. Additionally, in collaboration with AbCellera, we are developing precision ADCs with SMARCA payloads to extend the reach of our molecules to an even broader set of cancers without SMARCA4 mutations."

"Regarding our clinical development programs, we are very pleased with the progress of both of our SMARCA2 degraders, PRT3789 and PRT7732," added Jane Huang, M.D., President and Chief Medical Officer of Prelude. "We are looking forward to sharing the initial clinical data from the Phase 1 study of our highly selective SMARCA2 degrader which has been chosen as the subject of an oral presentation at the upcoming ESMO (Free ESMO Whitepaper) Congress in September."

Dr. Huang continued, "Additionally, based on the continued progress of PRT2527, our selective CDK9 inhibitor, we intend to present interim phase 1 clinical data, including a potential best-in-class safety profile in the fourth quarter of this year."

Clinical Program Updates and Upcoming Milestones

PRT3789 – A first-in-class, highly selective, intravenous SMARCA2 Degrader

PRT3789 is a first-in-class SMARCA2 degrader, highly selective for SMARCA2 and designed to treat patients with a SMARCA4 mutation. Cancer patients whose tumors have SMARCA4 mutations have a poor prognosis and as a result, this is an area of high unmet medical need.

PRT3789 is in Phase 1 clinical development in biomarker selected SMARCA4 mutant patients. Enrollment remains on track, and the Company expects to conclude monotherapy dose escalation in 2024 and identify a recommended Phase 2 dose. In addition, enrollment of patients into back-fill cohorts enriched for NSCLC and SMARCA4 loss-of-function mutations is ongoing, as is enrollment of the combination with docetaxel cohort.

Objectives for this first Phase 1 clinical trial are to establish the safety and tolerability profile of PRT3789 as both monotherapy and in combination with docetaxel, evaluate activity, pharmacokinetics and pharmacodynamics and determine a dose and potential indications for advancement into registrational clinical trial(s).

Prelude recently launched an educational video series focused on the science of SMARCA biology, the discovery of first-in-class, highly selective SMARCA2 degraders and the unmet medical need for patients with SMARCA4 mutated cancer. This series can be found on the Company’s website under Highly Selective SMARCA2 Degraders – Prelude Therapeutics (preludetx.com).

Interim Phase 1 data selected for an oral presentation at the ESMO (Free ESMO Whitepaper) Congress 2024

The abstract titled "First Clinical Results from a Phase 1 Trial of PRT3789, a First-in-Class Intravenous SMARCA2 Degrader, in Patients with Advanced Solid Tumors with a SMARCA4 Mutation," will be presented by Robin Guo, M.D. from Memorial Sloan Kettering Cancer Center. The ESMO (Free ESMO Whitepaper) Congress 2024 Scientific Committee selected the abstract as an oral presentation.

The presentation is scheduled for September 13th, 2024, at 4:00 PM CEST (10:00 AM EST) in the Santander Auditorium (Hall 5) as part of the Developmental Therapeutics Session.

Abstracts are anticipated to be available on the ESMO (Free ESMO Whitepaper) website on September 9th, 2024 at 12:05 AM CEST (6:05 PM EST on September 8th).

Clinical collaboration announced with Merck to evaluate PRT3789 in combination with KEYTRUDA in patients with SMARCA4-mutated cancers

In July 2024, Prelude announced a clinical collaboration with Merck to evaluate PRT3789 in combination with KEYTRUDA in patients with SMARCA4-mutated cancers.

The mechanistic rationale and pre-clinical data to support the SMARCA2 and anti-PD-1 monoclonal antibody (mAb) combination was previously presented by the Company at the 2023 AACR (Free AACR Whitepaper) AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper). In pre-clinical models, SMARCA2 degrader combined with an anti-PD-1 mAb in SMARCA4-mutated cancers enhanced anti-tumor immunity and demonstrated tumor regressions. Please see the Company’s website under Publications – Prelude Therapeutics (preludetx.com) for more information.

Under the terms of the Agreement, Merck will provide KEYTRUDA to Prelude. Prelude will be the sponsor of the Phase 2 clinical combination trial, anticipated to initiate in the fourth quarter of 2024. Prelude and Merck each retain all commercial rights to their respective compounds, including as monotherapy or as combination therapies.

KEYTRUDA is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

PRT7732 – A potent, highly selective and orally bioavailable SMARCA2 Degrader

Prelude has identified a series of highly selective and orally bioavailable SMARCA2 degraders. The lead oral candidate, PRT7732, recently was granted IND authorization from the FDA and is expected to enter Phase 1 clinical development in the second half of 2024.

PRT2527 – A potent and highly selective CDK9 Inhibitor

PRT2527 is a potent and highly selective CDK9 inhibitor that has the potential to avoid off-target toxicities observed with other less selective CDK9 inhibitors. The Company is currently advancing PRT2527 as monotherapy in both lymphoid and myeloid hematological malignancies, and in combination with zanubrutinib in B-cell malignancies.

PRT2527 is expected to complete monotherapy dose escalation in B-cell malignancies this year. Initiation of dose escalation in myeloid malignancies occurred in the first half of 2024. Interim Phase 1 data is on track for presentation in the fourth quarter of 2024.

Second Quarter 2024 Financial Results 

Cash, Cash Equivalents, and Marketable securities:

Cash, cash equivalents and marketable securities as of June 30, 2024 were $179.8 million. The Company anticipates that its existing cash, cash equivalents and marketable securities will fund Prelude’s operations into 2026. 

Research and Development (R&D) Expenses:

For the second quarter of 2024, R&D expense increased to $29.5 million from $25.0 million for the prior year period. Research and development expenses increased primarily due to an increase in our chemistry, manufacturing, and controls (CMC) expense to support our pre-clinical and clinical research programs. We expect our R&D expenses to vary from quarter to quarter, primarily due to the timing of our clinical development activities.  

General and Administrative (G&A) Expenses:

For the second quarter of 2024, G&A expenses increased to $7.7 million from $7.4 million for the prior year period. The increase is primarily due to an increase in professional fees incurred as we expand our operations to support our research and development efforts.

Net Loss:

For the three months ended June 30, 2024, net loss was $34.7 million, or $0.46 per share compared to $30.4 million, or $0.54 per share, for the prior year period. Included in the net loss for the quarter ended June 30, 2024, was $6.1 million of non-cash expenses related to the impact of expensing share-based payments, including employee stock options, as compared to $6.7 million for the same period in 2023.
