New Insights from Adagene on ADG126 at SITC
At the Society for Immunotherapy of Cancer (SITC) Annual Meeting, Adagene Inc. (Nasdaq: ADAG) presented compelling new data highlighting the enhanced therapeutic index of their innovative ADG126 therapy. With a focus on increased safety and efficacy, the posters shared at the conference describe the promising clinical profile of ADG126 both as a standalone treatment and in combination with the anti-PD-1 antibody, pembrolizumab.
Groundbreaking Clinical Findings
One of the key findings discussed involved the precision masking technology utilized by ADG126, which shows a marked improvement in patient safety compared to current standard therapies, like ipilimumab. This is attributed to the drug's ability to enhance antibody-dependent cellular cytotoxicity (ADCC) while partially blocking CTLA-4, a target that plays a pivotal role in immune evasion by tumors.
Clinical Implications for Colorectal Cancer
Data presented focused on patients with microsatellite-stable (MSS) colorectal cancers (CRC). Clinical investigators noted that combining ADG126 with pembrolizumab has demonstrated significant therapeutic benefits, enhancing the effectiveness of their treatment approach. The ability of ADG126 to deplete CTLA-4 expressing regulatory T cells (Tregs) in the tumor microenvironment is a critical element that prepares the immune system for a stronger response.
SITC's Top 100 Abstract Selection
Notably, the clinical data resulting from the study of ADG126 garnered significant attention at the conference, being selected as one of the top 100 abstracts from 1,439 submissions. This recognition underscores the potential impact of ADG126 in the field of cancer immunotherapy.
Poster Highlights
The first poster detailed the exploration of the enhanced therapeutic index of ADG126 over its unmasked counterpart, ADG116. Findings indicated that the masked form allows for higher dosing with reduced side effects, showcasing its effectiveness compared to existing treatments. Key points from the poster included:
- The unique epitope in ADG126 facilitates cross-reactivity among different species, enabling comprehensive PK modeling across preclinical studies.
- A comparative analysis demonstrated a three-fold increase in active drug exposure in tumors treated with a single dose of ADG126 versus ipilimumab, all while maintaining similar safety profiles.
Encouraging Results from Ongoing Trials
The second poster shared at SITC elaborated on the ongoing multicenter study combining ADG126 with pembrolizumab. Early data show promise, particularly concerning lower rates of treatment-related adverse events (TRAEs) compared to conventional anti-CTLA-4 therapies. In this trial, patients receiving ADG126 at 10 mg/kg in combination with pembrolizumab exhibited durable disease control and initial survival benefits.
Patient Case Studies
The effectiveness of ADG126 was reinforced by a patient case study showing a significant decrease in tumor size after treatment. A patient who was initially non-responsive to other therapies experienced an 80% reduction in target lesions, a feat frequently unattainable with existing alternatives. The treatment was well tolerated, with indications that this could mark a shift towards ADG126 being a vital part of future cancer therapies.
Future Directions for Adagene
Adagene is enthusiastic about the potential role of ADG126 in reshaping cancer treatment paradigms. Future trials aim to fortify findings, particularly analyzing the effects of varying dosage regimens in larger patient cohorts. The ongoing studies seek to explore both short-term and long-term outcomes as it relates to safety and efficacy.

Frequently Asked Questions
What is ADG126?
ADG126 is a masked anti-CTLA-4 SAFEbody designed by Adagene, intended to enhance the immune response against tumors while reducing adverse effects.
How does the masking technology work?
The precision masking employed in ADG126 shields the antibody's binding domain until it reaches the tumor microenvironment, allowing for targeted action and minimizing on-target off-tumor toxicity.
What were the significant results presented at SITC?
Key findings included a higher therapeutic index for ADG126 compared to existing therapies and encouraging early response rates in patients with MSS CRC.
How does ADG126 fare in combination with other therapies?
When combined with pembrolizumab, ADG126 demonstrated improved safety profiles and enhanced therapeutic outcomes, indicating significant potential for combinatorial cancer treatment approaches.
