Utilizing its innovative ADC payload platform, Akari is advancing a new class of immuno-oncology ADCs built on the platform of a novel PH1 payload, a spliceosome modulator that has a unique preclinical efficacy and safety profile with the potential to address unmet need for oncology patients singly or in combination with checkpoint inhibitors.

The full SITC (Free SITC Whitepaper) abstract, which included 2 figures, is now available here with the results summarized as follows:

In this work, Akari investigates the mechanism behind preclinical colon tumor regressions induced by a Trastuzumab PH1 ADC with/without anti-PD-1 and contrasts that against a first-in-class ADC with a microtubule inhibitor payload. A higher rate of complete regressions in the PH1 ADC combination vs comparator ADC combination is attributed to an immune response stimulated by neoantigen, activation of antigen-presenting cells, B, and T-cells, and a mechanistic synergy between the PH1 payload and the checkpoint inhibitor. Interestingly, while neither single agent induced gamma-delta T cells, a kind of T-cell that is not limited by low neoantigen expression in tumors or low numbers of antigen-presenting cells, the PH1 ADC together with anti-PD-1 agent expanded this tumor-killing T-cell population.

Further details will be released in the poster and oral presentations. Details are as follows:

"Our strong third-quarter performance demonstrates our strategic focus on commercial execution, pipeline development, and financial discipline. We are raising our full-year 2025 guidance due to our outstanding commercial performance year-to-date," said Raul Rodriguez, Rigel’s president and CEO. "Our development pipeline continues to advance, including our ongoing Phase 1b study evaluating R289 for the treatment of patients with lower-risk MDS. With enrollment complete in the dose escalation phase of the study, we look forward to presenting updated data in an oral presentation at ASH (Free ASH Whitepaper) in December. We’re also excited to have reached the next milestone of this program with the initiation of the dose expansion phase of the study."

Third Quarter 2025 Business Update

Commercial

Net product sales were $64.1 million, an increase of 65% from the same period of 2024.
TAVALISSE was commercially launched in South Korea in July by JW Pharmaceutical Corporation, the licensing partner of Kissei Pharmaceutical Co., Ltd. (Kissei), Rigel’s partner in certain Asian countries.
Clinical Development

Rigel continues to advance its Phase 1b clinical study evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of R2891, a potent and selective dual interleukin receptor-associated kinases 1 and 4 (IRAK1/4) inhibitor, in patients with relapsed or refractory (R/R) lower-risk myelodysplastic syndrome (MDS). Enrollment in the dose escalation phase of the study was completed in July. In October, Rigel announced the first patient was enrolled in the dose expansion phase of the study, where up to 40 patients will be randomized to either 500 mg once daily or 500 mg twice daily to determine the recommended Phase 2 dose for future clinical trials.
Rigel announced one oral presentation and four poster presentations highlighting data from its commercial and clinical-stage hematology and oncology portfolio at the upcoming 67th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition. The abstract with updated data from the ongoing Phase 1b study of R289 showed R289 continues to be generally well tolerated in a heavily pretreated lower-risk MDS patient population, the majority of whom were high transfusion burden at study entry, and preliminary signs of efficacy in dose levels of at least 500 mg once daily and higher. Updated data as of an October 28, 2025, data cut off will be presented in the oral presentation. The company will also present additional data for olutasidenib in patients with R/R mutated isocitrate dehydrogenase-1 (mIDH1) acute myeloid leukemia (AML).
The fifth study under the strategic alliance between Rigel and The University of Texas MD Anderson Cancer Center opened for enrollment in September. This Phase 2 multi-arm, multi-center, open-label, non-randomized clinical study will evaluate olutasidenib in combination with co-targeted therapies in patients with R/R IDH1-mutated myeloid malignancies harboring activated signaling pathway mutations (NCT07032727). The primary objectives of the study are to evaluate safety and the composite complete remission rate.
In October, the first patient was enrolled in the CONNECT Phase 2 TarGeT-D study evaluating olutasidenib in combination with temozolomide, followed by olutasidenib monotherapy as a maintenance regimen for newly-diagnosed adolescent and young adult patients with a high-grade glioma harboring an IDH1 mutation (NCT06161974).
Corporate

Eli Lilly and Company (Lilly) continues to advance ocadusertib (previously R552 or LY3871801), an investigational, potent and selective receptor-interacting protein kinase 1 (RIPK1) inhibitor. Enrollment in the Phase 2a clinical trial in adult patients with moderately to severely active rheumatoid arthritis is ongoing. Rigel will continue to be entitled to receive milestones and tiered royalty payments on future net sales of ocadusertib.
In early October, Rigel received notification from Lilly that it will terminate the central nervous system (CNS) disease program related to the collaboration between the two companies, which will become effective 60 days following notification.
Third Quarter 2025 and Year-to-Date Financial Update
For the third quarter ended September 30, 2025, total revenues were $69.5 million, consisting of $64.1 million in net product sales and $5.4 million in contract revenues from collaborations. Net product sales grew 65% compared to $38.9 million in the same period of 2024. TAVALISSE net product sales were $44.7 million, growth of 70% compared to $26.3 million in the same period of 2024. GAVRETO net product sales were $11.1 million, growth of 56% compared to $7.1 million in the same period of 2024. REZLIDHIA net product sales were $8.3 million, growth of 50% compared to $5.5 million in the same period of 2024. Contract revenues from collaborations primarily consisted of $3.1 million of revenue from Grifols S.A. (Grifols) related to delivery of drug supplies and earned royalties, $1.8 million of revenue from Kissei related to the delivery of drug supplies, and $0.2 million of revenue from Medison Pharma (Medison) related to delivery of drug supplies and earned royalties.

Total costs and expenses were $41.0 million compared to $41.3 million for the same period of 2024. The decrease in costs and expenses was mainly due to lower cost of product sales, as the prior period included a sublicensing fee. This decrease was partially offset by increased research and development costs driven by the timing of clinical activities related to olutasidenib and R289 and higher personnel-related costs.

Rigel reported net income of $27.9 million, or $1.55 basic and $1.46 diluted per share, compared to $12.4 million, or $0.71 basic and $0.70 diluted per share, for the same period of 2024.

For the nine months ended September 30, 2025, total revenues were $224.5 million, consisting of $166.6 million in net product sales and $57.9 million in contract revenues from collaborations. Net product sales grew 69% compared to $98.4 million in the same period of 2024. TAVALISSE net product sales were $113.3 million, growth of 54% compared to $73.8 million in the same period of 2024. GAVRETO net product sales were $31.9 million, growth of 252% compared to $9.0 million in the same period of 2024. GAVRETO became commercially available from Rigel in late June 2024. REZLIDHIA net product sales were $21.4 million, growth of 38% compared to $15.6 million in the same period of 2024. Contract revenues from collaborations primarily consisted of $40.0 million in non-cash revenue resulting from the release of the remaining cost share liability related to the agreement with Lilly for the development and commercialization of ocadusertib, $9.9 million of revenue from Grifols related to delivery of drug supplies and earned royalties, $6.9 million of revenue from Kissei related to a milestone payment and delivery of drug supplies and $0.8 million of revenue from Medison related to delivery of drug supplies and earned royalties.

Total costs and expenses were $122.2 million compared to $114.1 million for the same period of 2024. The increase in costs and expenses was mainly due to higher cost of product sales, increased research and development costs driven by the timing of clinical activities related to olutasidenib and R289, and higher personnel-related costs.

Rigel reported net income of $99.0 million, or $5.52 basic and $5.38 diluted per share, compared to $3.1 million, or $0.18 basic and diluted per share, for the same period of 2024.

Cash, cash equivalents and short-term investments as of September 30, 2025 was $137.1 million, compared to $77.3 million as of December 31, 2024.

2025 Outlook
Rigel is updating its 2025 total revenue guidance to approximately $285 to $290 million, an increase from the previous range of approximately $270 to $280 million, which includes:

Net product sales of approximately $225 to $230 million, an increase from the previous range of approximately $210 to $220 million.
Contract revenues from collaborations of approximately $60 million.
The company anticipates it will report positive net income for the full year 2025, while funding existing and new clinical development programs.

Leveraging ABL’s innovative ADC platform technology, NEOK is building a pipeline of bispecific ADCs by pursuing validated targets, while balancing high expression, selectivity, and target-related safety signals. NEOK utilizes a proprietary, linker-payload technology (SYNtecan E) that enables ADC generation with strong linker stability and superior biophysical properties. The company aims to overcome the efficacy and safety limitations of conventional ADCs through its bispecific approach which targets unique pairs of cancer targets.

"ADCs are a proven modality in treating select cancers, but historically have had limitations related to stability, selectivity, and therapeutic window. We believe our dual-targeting strategy has the potential to overcome drug resistance, target a wider range of tumors, increase internalization rates and cell killing, and improve the safety profile of ADCs by increasing selectivity and reducing off-tumor toxicity," said Mayank Gandhi, Chief Executive Officer of NEOK Bio. "The financing is a critical step in our journey to a clinical-stage company and enables the execution of a robust and efficient clinical development plan for our bispecific ADCs."

"Our investment in the formation of NEOK Bio underscores our commitment to deliver transformative therapeutic innovation to the dynamic and growing ADC landscape," said ABL Bio CEO Dr. Sang Hoon Lee. "We are excited to support an outstanding and experienced NEOK team as they aim to fulfill the significant untapped potential of bispecific ADCs to improve the lives of people with cancer."

The financing will support the initiation of clinical studies for NEOK’s two lead ADC candidates, which target proteins that are broadly expressed in multiple tumor types with significant unmet needs. They include NEOK001 (previously ABL206), a bispecific ADC targeting ROR1 and B7-H3, and NEOK002 (previously ABL209), a bispecific ADC targeting EGFR and MUC1 proteins. Both assets have the potential to demonstrate enhanced efficacy and safety over monovalent ADCs in large patient populations across thoracic, gastrointestinal, and gynecological cancers.

NEOK plans to file an Investigational New Drug (IND) application for both programs by early 2026 and initiate Phase 1 clinical trials in mid-2026 in the U.S. First data readouts from both programs are expected in 2027.
