  • Identified a predictive biomarker and two pharmacodynamic biomarkers that correlate with clinical efficacy and target engagement
  • ADG106, a fully human, ligand-blocking, agonistic anti-CD137 antibody demonstrated a favorable safety profile

SAN FRANCISCO, Calif. and SUZHOU, China, May 19, 2021 – Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biopharmaceutical company committed to transforming the discovery and development of novel antibody-based immunotherapies, today announced clinical data from its ADG106 NEObodyTM program. Results from Phase I, open-label, dose-escalation, single center (NCT03802955) and multicenter (NCT03707093) studies of ADG106 in subjects with advanced or metastatic solid tumors and/or relapsed/refractory non-Hodgkin lymphoma were presented in an abstract at the American Society of Clinical Oncology (ASCO) 2021 Annual Meeting. In these Phase I trials, ADG106 monotherapy exhibited a favorable safety profile and demonstrated promising clinical efficacy in biomarker positive patients. ADG106 is a fully human, ligand-blocking, agonistic anti-CD137 IgG4 antibody (mAb) engineered using Adagene’s proprietary NEObody platform technology.

“We are very pleased with the original finding of a predictive biomarker for our anti-CD137 agonist and its association with tumor shrinkage,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “ADG106 has been well tolerated in dose escalation and extensive expansion cohorts at dosage of up to 5 mg/kg, which exceeds that of other anti-CD137 agonists. Further, this clinical data demonstrates the power of our proprietary NEObody platform designed to generate antibodies with novel mechanisms of action by targeting unique and highly conserved epitopes. We believe these results, together with analyses of PK and PD data from around 100 patient population, support the recommended dose regimen for ongoing clinical development of ADG106 as monotherapy and in combination with anti-PD-1 and other therapies. We look forward to multiple upcoming studies as we continue to advance our ADG106 clinical program.”

“Predictive biomarkers for patient stratification are critical to advances in precision immuno-oncology. It’s compelling to identify a predictive biomarker for anti-CD137 agonism that shows a strong correlation between ADG106 treatment and tumor shrinkage,” said Hua Gong, M.D. Ph.D., Chief Operating Officer and Head of Precision Medicine of Adagene. “In an upcoming global Phase Ib/II trial (ADG106-2001), we plan to enrich for populations expressing our predictive biomarker in order to demonstrate a clinical benefit to ADG106 therapy. Our predictive biomarker has the potential to optimize favorable treatment options and enable oncologists to preselect cancer patients who are likely to benefit from ADG106 treatment. In our continuing commitment to the development of precision immunotherapies, Adagene has established a center of excellence for precision medicine in San Diego with cutting-edge technologies to support biomarker-guided clinical trials.”

Interim data for the ongoing Phase 1 clinical trial includes:

  • Biomarker studies: In a retrospective analysis, 75% of biomarker positive patients demonstrated more than 30% tumor shrinkage after ADG106 treatment.
    • Tumor shrinkage was not significant among biomarker negative patients. There was a strong negative correlation (100%) between biomarker absence and clinical response.
    • A tissue microarray study confirmed biomarker expression in a variety of tumor types suggesting a broad indication for ADG106 therapy.
  • Target engagement: Target engagement upon ADG106 treatment was demonstrated with dose-dependent increases in NK cells in ADG106-mediated anti-tumor activities and in dose-dependent induction of soluble CD137 over baseline.
  • Safety and efficacy: ADG106 demonstrated a disease control rate of 56% and exhibited a favorable safety profile at 3mg/kg and 5mg/kg with dose escalation up to 10mg/kg.

ADG106-1001 and ADG106-1002 Phase I trials have successfully completed enrollment of nearly 100 patients with advanced solid tumors and/or non-Hodgkin’s lymphoma in the US and China, respectively. Limited TEAEs, i.e., liver toxicity or hematologic abnormalities, were observed. Following a productive end-of-phase I (EOP1) meeting about our ADG106 biomarker-stratified trial design with the FDA, Adagene made a new submission (ADG106-2001) to stratify patients using the predictive biomarker prior to treatment with ADG106 as monotherapy and its combination with anti-PD-1 therapy. In March 2021, Adagene initiated patient enrollment in China for ADG106-1008 (NCT04775680) a multicenter, open-label, Phase Ib/II study of ADG106 in combination with PD-1 antibody in advanced solid tumors and relapsed/refractory non-Hodgkin lymphoma. Preparations are underway for the ADG106-1003 trial in Australia to evaluate ADG106 in combination with other therapies in advanced solid tumors and hematological malignancies.

About ADG106

ADG106, is a fully human ligand-blocking, agonistic anti-CD137 Immunoglobulin G4, or IgG4, mAb, being developed for the treatment of advanced solid tumors and non-Hodgkin’s lymphoma, or NHL. CD137 stimulates the immune system to attack cancer cells and is a key driver for long-lasting T-cell proliferation and survival. In preclinical studies, we observed that ADG106 had robust antitumor activity and was well tolerated as a single agent and in combination with the existing standard-of-care and other immuno-oncology therapies. ADG106 activates CD137 in a native ligand-like fashion, blocks reverse signaling of CD137 ligand, and has potent cross-linking via Fc receptor. Because of this novel mechanism of action, ADG106 was observed to favorably balance CD137-induced toxicity and CD137 agonism, which we believe has potential to address the limitations of other existing anti-CD137 therapies.

SAN FRANCISCO, Calif. and SUZHOU, China, April 13, 2021 – Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biopharmaceutical company committed to transforming the discovery and development of novel antibody-based immunotherapies, today announced updated preclinical data from its lead SAFEbodyTM program, ADG126, are being presented at the American Association for Cancer Research (AACR) Annual Meeting 2021.

“There is a critical unmet need for new anti-CTLA-4 therapies, and we are encouraged by the data generated to date, which demonstrate ADG126 has the potential to overcome the severe immune-mediated adverse reactions associated with the class,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “By leveraging our SAFEbody platform technology, designed to precisely and very efficiently mask the antibody binding interface and activate specifically within the tumor microenvironment, our preclinical data continues to highlight the opportunity to effectively deliver treatment; ADG126 has demonstrated superior systemic safety at efficacious dose levels with a significantly enlarged therapeutic index (TI). Our ongoing global Phase 1 trial is expected to provide clinical validation for our SAFEbody platform and our SAFEbody product, ADG126.  We have successfully finished DLT evaluation of 3 patients at 0.1 mg/kg of ADG126 and remain on track to report topline safety and efficacy data in the second half of 2021.”

A copy of the poster presentation, entitled “A Novel Anti-CTLA-4 Checkpoint Inhibitor Prodrug to Address On-target Off-tumor Toxicity for Cancer Immunotherapy,” is available on the AACR website and is also available for download via our website (https://test.adagene.com/pipeline/publications/).

The data presented show:

  • Notable Findings: ADG126 demonstrated an impressive safety margin while maintaining its potent antitumor efficacy.
  • Unique Epitope with Broad Species Cross-Reactivity: ADG126 targets a conserved epitope of CTLA-4 with broad species cross-reactivity and is an activatable prodrug for tumor suppression in multiple syngeneic mouse models in single and combination therapies.
  • Differentiated Mechanism of Action: Although the activated ADG126 is softer in blocking CTLA-4 binding with its ligands than ipilimumab, the activated ADG126 exhibited more potent antibody dependent cellular cytotoxicity (ADCC) in the tumor microenvironment.
  • Intra-Tumoral Treg Depletion: Treg cells in tumor tissues exhibited higher CTLA-4 expression than in peripheral tissues and were efficiently depleted upon treatment with ADG126 in the immune-competent mouse syngeneic colon tumor model.
  • Human T-Cell Activation in Vitro: Activated ADG126 potently enhanced T-cell activation, measured by IL-2 secretion, whereas the masked ADG126 did not.
  • In Vivo Monotherapy Efficacy: ADG126 exhibited potent antitumor activity as a single agent in different immune-competent syngeneic mouse tumor models.
  • In Vivo Combination Efficacy: ADG126 combined synergistically with other IO agents, such as anti-PD-1 antibody, to inhibit tumor growth in vivo. Combination therapy significantly slowed tumor growth and caused complete regression in 50% of Lewis lung cancer mouse models.
  • Safety and Tolerability: ADG126 was well tolerated in animals suggesting the potential for high therapeutic index. The highest non-severely toxic dose (HNSTD) was determined to be 200 mg/kg/dose, which is one of the highest reported HNSTD for anti-CTLA4 antibody.

About ADG126

ADG126 is a fully human antagonistic mAb targeting a novel epitope of CTLA-4 and has been shown to specifically deplete regulatory T-cells in tumors. ADG126 is Adagene’s lead SAFEbody™ product candidate. The SAFEbody technology, developed using Adagene’s AI-powered platform, enables binding of an antibody to a specific target only after conditional activation of the antibody in target tissues.

In preclinical studies, ADG126 was well tolerated in cynomolgus monkeys and demonstrated an encouraging antitumor response in multiple immune-competent mouse tumor models in a dose-dependent manner both as a single agent and in combination with anti-PD-1 and other therapies.

Unlike anti-PD-1/PD-L1 check point inhibitors, anti-CTLA-4 is known for its dose-dependent clinical response in single and combination therapies, which is severely limited by the narrow therapeutic window available to current anti-CTLA-4 therapies.  The large safety margin shown by ADG126 GLP toxicology studies of up to 200 mg/kg in targeting CTLA-4 will make it possible to dose patients for their optimal clinical benefits in single and combination therapies.

Full-Year 2020 Financial Highlights

Cash and Cash Equivalents
Our Cash and cash equivalents decreased by 19% from approximately US$92.5 million as of December 31, 2019 to approximately US$75.2 million as of December 31, 2020. The decrease in cash and cash equivalents was mainly due to increased cash outflows arising from operating activities. Moreover, Adagene successfully completed its IPO in February 2021, resulting in gross proceeds of approximately US$161 million.

Net Revenue
Our net revenue increased by 46% from US$0.5 million in 2019 to US$0.7 million in 2020. For the year ended December 31, 2019, we recognized revenue of US$0.5 million from Signal Pharmaceuticals LLC, a subsidiary of Celgene Corporation. For the year ended December 31, 2020, we recognized revenue of US$0.3 million, US$0.23 million and US$0.15 million from Signal Pharmaceuticals LLC, ADC Therapeutics SA and Tanabe Research Laboratories, Inc. respectively.

As we have received US$11 million from Exelixis in March 2021, we expect that our net revenue for Year 2021 will be significantly higher than that of Year 2020.

Research and Development Expenses
Our research and development expenses increased by 107% from US$16.2 million in 2019 to US$33.5 million in 2020, primarily attributable to (i) an increase in payroll and other related costs of personnel due to headcount growth in research and development and increased share-based compensation expenses and (ii) an increase in costs related to preclinical testing and clinical trials due to progression of the programs and increased contract manufacturing costs.

General and Administrative (G&A) Expenses
Our administrative expenses increased by 200% from US$3.4 million in 2019 to US$10.3 million in 2020. The increase was primarily due to a rise in average payroll, an increase in the number of employees and increased share-based compensation expenses.

Net Loss
Our net loss attributable to Adagene Inc.’s shareholders increased by 158% from approximately US$16.4 million in 2019 to approximately US$42.4 million in 2020.

Non-GAAP Net Loss
Non-GAAP net loss, which is defined as net loss attributable to ordinary shareholders for the period after excluding (i) share-based compensation expenses and (ii) accretion of convertible redeemable preferred shares to redemption value, increased by 104% from approximately US$15.8 million in 2019 to approximately US$32.3 million in 2020. Please refer to the section in this press release titled “Reconciliation of GAAP and Non-GAAP Results” for details.

Non-GAAP Financial Measures

The Company uses non-GAAP net loss and non-GAAP net loss per ordinary share for the year/period, which are non-GAAP financial measures, in evaluating its operating results and for financial and operational decision-making purposes. The Company believes that non-GAAP net loss and non-GAAP net loss per ordinary share for the year/period help identify underlying trends in the Company’s business that could otherwise be distorted by the effect of certain expenses that the Company includes in its loss for the year/period.

  • NEObody™ product candidate ADG116 has been well tolerated in ongoing Phase 1 clinical trial
  • Promising pharmacodynamic biomarker signals demonstrate clinical proof of mechanism
  • Poised for global expansion

SAN FRANCISCO, Calif. and SUZHOU, China, March 29, 2021 – Adagene Inc. (Nasdaq: ADAG), a platform-driven, clinical-stage biopharmaceutical company committed to transforming the discovery and development of novel antibody-based immunotherapies, today announced the interim dose-escalation data up to 0.3 mg/kg in its ongoing Phase 1 clinical trial in Australia evaluating the safety and tolerability of ADG116 in patients with advanced/metastatic solid tumors. ADG116 is a fully human, anti-CTLA-4 monoclonal antibody (mAb), designed to target a unique conserved epitope of CTLA-4 and utilizes Adagene’s proprietary NEObody platform technology. ADG116 is designed to balance safety and efficacy through a novel mechanism of action; ADG116 maintains its original physiological function via partial blocking of CTLA-4 ligand binding, and in conjunction, depletes Treg in the tumor microenvironment via strong antibody-dependent cellular cytotoxicity (ADCC).

Interim data for the ongoing Phase 1 clinical trial:

  • Safety: Analysis of all safety data generated to date demonstrates that ADG116 has been well-tolerated in more than 10 patients with no dose-limiting toxicities or unexpected safety signals. No drug related Grade 3 and Grade 4 toxicities have been observed.
  • Notable findings in pharmacodynamics: A dose-dependent change in CD8+ and CD4+ TEM / Treg ratios, important pharmacodynamic (PD) biomarkers indicating immune activation, was observed for patients dosed by ADG116. In particular, a patient, refractory to prior pembrolizumab therapy (> 25 cycles), demonstrated striking increases in T and NK cells, and CD8+ and CD4+ TEM / Treg The Grade 1 treatment-related pruritus of this patient is a clinical symptom consistent with immune-mediated action of ADG116 treatment.
  • Pharmacokinetics: The terminal half-life of ADG116 was within the normal range of IgG1 based antibodies.
  • Clinical proof of mechanism: The Phase 1 dose escalation data demonstrates the clinical proof of mechanism for ADG116 in targeting CTLA-4, consistent with preclinical observations for the potency of ADG116 starting from 0.03 to 0.3 mg/kg.

“We are encouraged by the positive PD marker signals and safety data,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “It is particularly striking to observe immune activation biomarkers at 0.03 mg/kg, especially in the patient refractory to prior pembrolizumab therapies. We believe ADG116 has the potential to overcome the limitations of anti-CTLA-4 checkpoint inhibitors, extending the market potential beyond current anti-CTLA-4 inhibitors in both monotherapy and combination settings. Our highly differentiated anti-CTLA-4 therapeutics hold the potential to improve the clinical benefits by expanding clonal diversity, infiltrating into cold tumors, and treating patients resistant/refractory to current immuno-therapies.”

“We look forward to developing a comprehensive clinical program to evaluate each of our anti-CTLA-4 assets,” continued Dr. Luo. “We will leverage the modality-specific features demonstrated in the preclinical setting, that enable high-fidelity translation into the clinic by targeting unique, highly conserved epitope of CTLA-4 with broad species cross-reactivity. We remain committed to maximizing the full potential of our unique anti-CTLA-4 approach.”

The progression of the Phase 1 dose-escalation trial to the 5th dose, a 0.3mg/kg dose level, builds on encouraging signs of PD markers, normal PK data, strong early clinical data, extensive preclinical and safety tolerability data and a successful Safety Review Committee meeting. Multiple clinical sites are currently open in Australia. In this ongoing Phase 1 clinical trial of ADG116 in patients with advanced/metastatic solid tumors, no dose-limiting toxicity (DLT), treatment-related serious adverse events (SAEs), colitis or hepatitis have been observed. With favorable clinical data to date, Adagene looks forward to expanding the ongoing global Phase 1 trial, with the acceptance of revised study protocol by FDA to expand the trial in the U.S. Adagene has also obtained confirmation from China NMPA to proceed with revised protocol submission at higher starting dose than that in the original submission. Additional information about this clinical trial is available at ClinicalTrials.gov using the identifier: NCT04501276.

About ADG116

ADG116 is a fully human ligand-blocking anti-CTLA-4 mAb generated using NEObody technology. ADG116 is a differentiated anti-CTLA-4 approach, which leverages Adagene’s Dynamic Precision technology to target a conserved epitope with broad species cross-reactivity for translational fidelity and a unique CTLA-4 mechanism of action. In preclinical studies, ADG116 was observed to have softer CTLA-4 ligand blocking and stronger ADCC for depleting regulatory T-cells than ipilimumab. In a head-to-head in vivo efficacy study, ADG116 was observed to have at least a five-fold greater preclinical antitumor activity in comparison with ipilimumab. In preclinical studies, ADG116 was well tolerated in rats and cynomolgus monkeys in four-week repeat-dose GLP toxicology studies at doses up to 30 mg/kg, and demonstrated an encouraging antitumor response in multiple immune-competent mouse tumor models in a dose-dependent manner both as a single agent (showing initial response at 0.02mg/kg, and complete response at 0.1 mg/kg for tumor size of ~100mm3 in sensitive tumor models) and in combination with other therapies.

-SAFEbody technology enables precision masking of antibodies for enhanced safety-

SAN FRANCISCO, Calif. and SUZHOU, China, March 16, 2021 – Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biopharmaceutical company committed to transforming the discovery and development of novel antibody-based immunotherapies, today announced the first patients have been dosed in its global Phase 1 clinical trial of ADG126 for the treatment of various advanced solid tumors. ADG126 is a fully-human, antagonistic monoclonal antibody (mAb) targeting a novel epitope of CTLA-4 and is Adagene’s lead SAFEbody™ product candidate.

“Dosing the first patients in our Phase 1 clinical trial of ADG126 is an exciting milestone for the development of our SAFEbody technology platform,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “SAFEbody technology is designed to mask antibody binding sites, which will be activated specifically within the tumor microenvironment (TME), to provide favorable safety and efficacy with significantly enhanced therapeutic windows. Our most advanced SAFEbody candidate, ADG126 targets a conserved epitope of CTLA-4 with broad species cross-reactivity for potent Treg depletion via strong antibody dependent cellular cytotoxicity (ADCC) in TME versus peripheral tissue. Our preclinical studies provide proof-of-concept for the potential of ADG126 in leveraging our SAFEbody platform to overcome standing issues associated with existing anti-CTLA-4 therapies by limiting on-target off-tumor toxicities in normal tissues.”

“Existing cancer therapies that target CTLA-4 are associated with safety concerns, creating an unmet need for new anti-CTLA-4 therapies that are both safe and potent,” said Anthony W. Tolcher, M.D., FRCPC, FACP, medical oncologist, co-founder of NEXT Oncology ™, Adagene advisor and study investigator. “ADG126 demonstrated an impressive safety margin while maintaining its potent antitumor efficacy in pre-clinical studies, and I look forward to its evaluation in patients with advanced solid tumors.”

The global Phase 1 open-label, dose-escalation clinical trial is investigating the tolerability and anti-tumor activity of ADG126 in patients with advanced/metastatic tumors in multiple clinical sites in Australia. Adagene has also received approval from the FDA to initiate the Phase 1 clinical trial of ADG126 in the United States. The dose escalation trial will test five doses at 0.1, 0.3, 1.0, 3.0 and 10 mg/kg, with dose-limiting toxicities (DLT) evaluation for 3 weeks. Additional information about this clinical trial is available at ClinicalTrials.gov using the identifier: NCT04645069.

About ADG126

ADG126 is a fully human antagonistic mAb targeting a novel epitope of CTLA-4 and has been shown to specifically deplete regulatory T-cells in tumors. ADG126 is Adagene’s lead SAFEbody™ product candidate. The SAFEbody technology, developed using Adagene’s AI-powered platform, enables binding of an antibody to a specific target only after conditional activation of the antibody in target tissues.

In preclinical studies, ADG126 was well tolerated in cynomolgus monkeys in a four-week repeat-dose GLP toxicology study at doses up to 200 mg/kg, and demonstrated an encouraging antitumor response in multiple immune-competent mouse tumor models in a dose-dependent manner both as a single agent and in combination with anti-PD1 and other therapies.

Unlike anti-PD1/PD-L1 check point inhibitors, anti-CTLA-4 is known for its dose-dependent clinical response in single and combination therapies, which is severely limited by the narrow therapeutic window available to current anti-CTLA-4 therapies.  The large safety margin shown by ADG126 GLP toxicology studies of up to 200 mg/kg in targeting CTLA-4 will make it possible to dose patients for their optimal clinical benefits in single and combination therapies.

Exelixis will utilize Adagene’s proprietary SAFEbody™ technology to develop novel masked antibody-drug conjugates (ADCs) with potential for improved therapeutic index

Adagene, Exelixis

ALAMEDA, Calif., SAN FRANCISCO, Calif. & SUZHOU, China – February 1, 2021 – Exelixis, Inc. (Nasdaq: EXEL) and Adagene today announced a collaboration and license agreement under which Exelixis will utilize Adagene’s SAFEbody™ technology platform to generate masked versions of monoclonal antibodies from Exelixis’ growing preclinical pipeline for the development of ADCs or other innovative biologics against Exelixis-nominated targets. Under the terms of the agreement, Exelixis will make an upfront payment of $11 million to Adagene and will have the ability to nominate two targets during the collaboration term. Adagene will be eligible for development and commercialization milestones, as well as royalties on net sales of products developed around each of these targets.

“SAFEbody provides a solution to on-target off-tumor toxicity, which is a long-lasting challenge associated with many approved antibody therapeutics,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer, and Chairman of Adagene. “This partnership with Exelixis strengthens our growing roster of collaborations with global biopharmaceutical companies. We are very pleased to collaborate with Exelixis and look forward to the company’s development of ADCs that leverage our SAFEbody technology.”

Biologic therapies, including therapeutic antibodies such as ADCs, are designed to bind to their targets with high efficiency. However, while the targets for biologic cancer therapies are expressed at high levels in cancer cells, many are also expressed at lower levels on healthy cells. Binding of these therapies to healthy cells may lead to unwanted safety or tolerability issues. Adagene’s SAFEbody platform is designed to overcome this challenge by incorporating a masking peptide that covers the binding domain of the biologic therapy. Specific conditions within the tumor environment allow the biologic therapy to preferentially bind to its target in tumor cells. This allows for improved tumor-specific targeting of antibodies while minimizing on-target toxicity in healthy tissues. Adagene’s most advanced SAFEbody candidate has been approved to start a clinical trial in Australia and the United States.

“As we expand our pipeline beyond small molecule therapies, we are committed to developing novel biotherapeutics that are optimized for safety and efficacy,” said Peter Lamb, Ph.D., Executive Vice President, Scientific Strategy and Chief Scientific Officer of Exelixis. “We believe the SAFEbody platform has the potential to significantly improve the safety profile of ADCs, and we will initially focus on incorporating this innovative technology into novel ADCs that also utilize next-generation linkers and payloads. The combination of these cutting-edge technologies is expected to yield ADC product candidates with differentiated target profiles and/or improved therapeutic indices. We are committed to expanding our development pipeline into additional therapeutic classes even as we drive additional momentum toward broadening the label for cabozantinib into additional cancer indications.”
