Dr. Matthias Will, Chief Development Officer of Autolus, said: "Patients with srSLE have limited remaining treatment options and represent a difficult to treat population with a critical unmet need. Data reported from the CARLYSLE trial show an encouraging high rate of DORIS responses and a deep reset in the B cell compartment induced by obe-cel, suggesting the possibility for an immune reset. Based on this positive initial experience with obe-cel in the CARLSYLE trial we have initiated the LUMINA trial, a Phase 2 trial in lupus nephritis with registrational intent."

Summary: Updated Phase 1 data with longer follow-up, and data in patients who received both 50×106 (50M) and 100×106 (100M) CAR T-cells were presented. Nine adult patients were infused with obe-cel, including six at the 50M dose and three at the 100M dose.

Obe-cel was well tolerated in all patients. No dose limiting toxicities (DLTs) or cases of immune effector cell-associated neurotoxicity syndrome (ICANS) were observed at the 50M dose. Grade one cytokine release syndrome (CRS) was observed in three patients at the 50M dose and three patients at the 100M dose. Hypertension was observed in five patients at the 50M dose, with three of those patients having pre-existing history of hypertension. A case of transient Grade three liver toxicity was observed in one patient of the 100M cohort.

At the 50M dose, three patients (50%) achieved CRR and five patients (83%) achieved DORIS with a median onset of 5.1 months (range: 4.9–8.9), without evidence of new disease activity at a median of 12 months of follow up (range: 8.5–16.3). All non-renal manifestations of the disease resolved by month four. Urinary protein creatinine (UPC) ratio levels decreased over time, demonstrating significant decline or absence of disease activity. Data show high peak expansion and deep B cell aplasia consistent with known obe-cel characteristics in oncology indications. Peak expansion was reached at a median of 10 days (range: 9–13). The median time to loss of CAR T-cell persistence based on Kaplan-Meier analysis was 3.0 months. The B-cell reconstitution profiles suggest that obe-cel may induce a reset of pathologic autoimmunity.

Emerging data in the 100M cohort is consistent with the 50M adult cohort, and evaluation is ongoing.

Data support progressing obe-cel as a treatment for srSLE and 50M has been selected as the recommended Phase 2 dose. Autolus has aligned with U.S. Food and Drug Administration (FDA) on a Phase 2 trial design in LN and potential registrational path to approval. The LUMINA trial is now enrolling.

Dr. Christian Itin, Autolus Chief Executive Officer, said: "Obe-cel’s safety profile is based on a robust database spanning several clinical trials in B-ALL and B-NHL indications. Data presented today now also show the ability to induce deep depletion of B-cell lineages in patients with srSLE. Obe-cel successfully underwent the regulatory approval process with the FDA, EMA and MHRA in adult r/r B-ALL and launched commercially in the US and UK in 2025. Building on this strong foundation of clinical data, and demonstrated commercial and manufacturing capabilities, we believe Autolus is well positioned for a successful and efficient path into the autoimmune setting."

Dr. Matthias Will, Chief Development Officer of Autolus, said: "Pediatric patients with r/r B-ALL have a poor prognosis, particularly those who relapse early. We were pleased to share the first data from the Phase 1 CATULUS trial showing obe-cel can produce high remission rates in this pediatric patient population, including in patients with high-risk relapse and patients with primary CNS relapse. Consistent with our experience in the adult population, data show low rates of severe CRS and ICANS. We are now advancing into the Phase 2 portion of the study in line with our commitment to address the significant unmet need for new treatment options for pediatric patients with r/r ALL."

Dr. Will continued, "Insights from post-hoc analyses from our FELIX pivotal trial in r/r adult B-ALL explored various factors that may help to predict long-term patient outcomes. Specifically, investigators showed that detection of obe-cel in the blood three months post-treatment may be a predictor for long-term outcomes. They also identified characteristics of the product’s cell phenotype as additional factors for treatment outcomes."

He concluded, "In addition to Autolus’ presentations, we were highly encouraged by data from the real-world experience of the ROCCA consortium evaluating CAR T therapy for r/r adult ALL patients. These real world data mirror obe-cel’s safety profile observed in the pivotal FELIX trial with low single digits rates of CRS and ICANS as one of the differentiating characteristics of the therapy."

Summary: CATULUS is a single-arm, open-label, multi-center study enrolling high-risk patients under age 18 with r/r B-ALL that is primary refractory, in high-risk first relapse, or in second or later relapse. The safety profile of obe-cel in pediatric patients was consistent with that previously reported in adults, with low rates of high-grade CRS and ICANS (both 8.7%). The ORR was high at 95.5% (n=21), with 90.9% (n=20) achieving complete response (CR). Twenty patients were in ongoing remission at data cut-off with a median follow-up of 8.8 months. These preliminary findings support further exploration of obe-cel in pediatric R/R B-ALL and planning for the Phase II expansion is underway.

Summary: Of 99 patients who achieved remission (CR/CRi) in the FELIX study, 79 (79.8%) had ongoing remission at month three following obe-cel infusion and comprised the subgroup of interest for the analyses. At month three post infusion, 60/79 patients (75.9%) had ongoing CAR T-cell persistence, while 19/79 patients (24.1%) had loss of persistence. In patients who remained in remission beyond month three, including those with deep MRD-negative remission and no post obe-cel SCT, ongoing CAR T-cell persistence at month three, measured by droplet digital PCR (ddPCR), was associated with longer event-free survival (EFS) and overall survival (OS) compared with loss of persistence. These results suggest that persistence status at month three may be a marker for predicting long-term outcomes following obe-cel treatment in patients with r/r B-ALL.

Summary: Measuring obe-cel expansion and persistence using flow cytometry (FC) is feasible with commercially available antibodies that directly target regions of the CAR construct, such as the G4S linker. These reagents show high correlation with anti-idiotype antibodies and provide a reliable method for tracking CAR expression in patients. Use of the G4S binder enabled tracking of CAR T expansion kinetics and phenotypic profiles in patients with different disease burdens. Reagents based on the CD19 protein, commonly used in other CAR T therapies, are unsuitable for obe-cel due to the unique features of the CAT19 binder, which limits effective detection.

Summary: Clinical data show the potential for obe-cel to produce long-term outcomes. This analysis details certain product features potentially affecting clinical outcomes, including how drug product phenotypes correlate with treatment outcomes following infusion with obe-cel. A higher percentage of central memory cells (Tcm) in the drug product samples was an independent predictor of positive clinical outcomes, including overall survival (OS), following obe-cel infusion. While the T-cell phenotype composition in the leukapheresis product (LP) was weakly correlated with that in the drug product, CD25+ HLADR+ CD4+ cells in the LP independently predicted less favorable clinical outcomes. However, other factors (e.g. tumor characteristics) are also likely to affect outcomes; therefore, further investigations are needed to better understand and predict favorable clinical outcomes, and to potentially guide studies of additional cell manipulations during CAR T-cell manufacturing.

"At ASH (Free ASH Whitepaper) 2025, we will present new data from across our CLL franchise, highlighting both the strength of BRUKINSA and the potential of BGB-16673," said Amit Agarwal, M.D., Ph.D., Chief Medical Officer, Hematology, BeOne. "Long-term data are the gold standard in CLL, and BRUKINSA continues to deliver the high levels of durable progression-free and overall survival that patients and physicians should demand from a BTK inhibitor. BGB-16673, the most advanced BTK degrader in the clinic with over 800 patients dosed to date, potentially represents the next wave of foundational innovation in oncology."

BRUKINSA continues to demonstrate unprecedented long-term efficacy with a favorable safety profile over more than six years of follow-up in treatment-naïve CLL/SLL.

In SEQUOIA (NCT03336333), a randomized, multicenter, global Phase 3 trial, BRUKINSA maintained progression-free survival (PFS) superiority versus bendamustine plus rituximab (BR) with an estimated 74% PFS at six years in treatment-naïve CLL or small lymphocytic lymphoma (SLL) compared with 32% PFS for BR. Highlights include:

Arms A, B and C: BRUKINSA vs BR, as well as BRUKINSA in patients with del(17p) (Poster Presentation: 2129)
COVID-19 adjusted PFS rates were 77% (95% CI, 70.1-81.8) for BRUKINSA and 33% (95% CI, 25.5-40.4) for BR.
The overall survival (OS) at 72 months was 84% for BRUKINSA and 80% with BR. After adjusting for COVID-19, the OS rates were 88% and 82%, respectively.
In patients with del(17p), the six-year PFS was 64% (65% after COVID-19 adjustment) and the 72-month OS was 83%.
The safety profile of BRUKINSA was consistent with the results of prior studies with no new safety signals identified.
"SEQUOIA’s longer follow-up strengthens the evidence for continuous zanubrutinib use," said Constantine Tam, M.B.B.S., M.D., Head of Lymphoma Service at Alfred Health and Professor of Haematology at Monash University. "Patients continued to show durable disease control and consistent safety across study arms, meaningfully raising the bar for CLL patients, including those with harder-to-treat CLL."

Arm D: BRUKINSA plus venetoclax in patients with or without del(17p) and/or TP53 mutations (Poster Presentation: 5669)
In the overall patient population, in which 58% of patients had del(17p) and/or TP53 mutation, the median PFS was not reached; the 36-month PFS rate was 87%.
The 36-month PFS rate for patients with del(17p) and/or TP53 mutation was 87% and for patients without del(17p) and TP53 mutation was 89%.
A total of 42 patients completed the BRUKINSA plus venetoclax combination and continued BRUKINSA monotherapy.
At 12 months following the combination period, peripheral blood undetectable minimal residual disease (uMRD) was maintained in 100% (18/18) of patients without del(17p) and TP53.
At 18 months following the combination period, uMRD was maintained in 92% (22/24) of patients with del(17p) and/or TP53 mutation.
The safety profile of BRUKINSA plus venetoclax was generally tolerable and no unexpected safety signals were identified.
The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) now recommend zanubrutinib plus venetoclax as a preferred first-line regimen for CLL/SLL.
New patient-reported outcomes data in R/R CLL suggest BRUKINSA may offer a more manageable side effect profile. Up to six-years of follow-up data support BRUKINSA’s foundational role in CLL/SLL as the only BTK inhibitor with enduring PFS and long-term benefit over another BTK inhibitor.

ALPINE (NCT03734016) is a global, randomized, open-label, multicenter, Phase 3 study of BRUKINSA versus ibrutinib in patients with R/R CLL/SLL who received ≥1 prior systemic therapy. Highlights include:

Symptom-based progression-free survival as a clinically relevant and patient-centric endpoint (Oral Presentation: 711)
This study is among the first analyses of patients with CLL/SLL to demonstrate a statistically and clinically meaningful association between longitudinal symptom deterioration and disease progression using joint modeling.
Deterioration in patient-reported fatigue, insomnia, and nausea/vomiting emerged as strong symptomatic indicators of disease progression.
Compared with ibrutinib, patients on BRUKINSA showed reduced risk of symptom deterioration associated with earlier disease progression.
The analysis showed that patients on BRUKINSA had lower odds of symptom worsening for nausea/vomiting, fatigue, pain, and insomnia.
Up to six years of follow-up of patients from the BRUKINSA arm of ALPINE who continued in a long-term extension study (LTE-1; Poster Presentation: 2123)
With up to 73.5 months of follow-up, the median PFS for all patients was a striking 52.5 months; the 60-month PFS rate was 47.3% (50.4% adjusted for COVID-19). These results redefine what is expected for this patient population.
Among patients with del(17p), the median PFS was 49.9 months; the 60-month PFS rate was 38.2% (40.5% adjusted for COVID-19).
With longer follow-up, the prevalence of most adverse events of special interest remained stable year-over-year.
BGB-16673 (BTK degrader) clinical data demonstrates rapid, robust and deepening responses in patients with heavily pretreated R/R CLL/SLL, including those with prior BTKi treatment and mutations that confer resistance to BTK inhibitors. (Oral Presentation: 85)

Updated results from CaDAnCe-101 (NCT05006716), an ongoing open-label, Phase 1/2 study evaluating BGB-16673 monotherapy in patients with B-cell malignancies, showed responses across R/R CLL/SLL patient types, including those who had previously been treated with BTK inhibitors, BCL2 inhibitors, noncovalent BTK inhibitors, and those with BTK inhibitor resistance mutations. Highlights include:

With a median follow-up of 19.8 months, 54.4% of patients remain on treatment. Across all doses, ORR was 85.3% and CR/CR with incomplete count recovery (CRi) rate was 2.9% with responses deepening over time.
In the group of patients dosed at the recommended phase 2 dose (RP2D; 200 mg QD), ORR was 94.4%.
In the patients with prior covalent BTK inhibitor, BCL2i, and noncovalent BTK inhibitor treatment, ORR was 75.0%.
The 12- and 18-month PFS rates were 73.5% and 65.9% respectively.
BGB-16673 was generally well tolerated in this heavily pretreated population with no treatment-related deaths and no new toxicities identified with a median treatment duration of 13.6 months.

About Chronic Lymphocytic Leukemia

Chronic lymphocytic leukemia (CLL) is a life-threatening cancer of adults. It is a type of mature B-cell malignancy in which abnormal leukemic B lymphocytes (a type of white blood cells) arise from the bone marrow and flood peripheral blood, bone marrow, and lymphoid tissues.1,2 CLL is the most common type of leukemia in adults, accounting for about one-third of new cases.2,3

About BGB-16673

BGB-16673 is a potential first-in-class Bruton’s tyrosine kinase (BTK) protein degrader and is the most advanced protein degrader in the clinic, with nearly 800 patients dosed to date in an extensive global clinical development program. This program includes three randomized Phase 3 trials in R/R CLL, including the head-to-head Phase 3 trial versus pirtobrutinib, which began enrolling in Q4 2025. Originating from BeOne’s chimeric degradation activation compound (CDAC) platform, BGB-16673 is designed to promote the degradation, or breakdown, of both wildtype and mutant forms of BTK, including those that commonly result in resistance to BTK inhibitors in patients who experience progressive disease.

The U.S. Food and Drug Administration (FDA) granted Fast Track Designation to BGB-16673 for the treatment of adult patients with relapsed or refractory (R/R) chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL), and adult patients with R/R mantle cell lymphoma (MCL). Additionally, the European Medicines Agency (EMA) granted BGB-16673 PRIority MEdicines (PRIME) designation for the treatment of patients with Waldenstrom’s macroglobulinemia (WM) previously treated with a BTK inhibitor.

About BRUKINSA (zanubrutinib)

BRUKINSA is an orally available, small molecule inhibitor of Bruton’s tyrosine kinase (BTK) designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.

BRUKINSA has the broadest label globally of any BTK inhibitor and is the only BTK inhibitor to provide the flexibility of once or twice daily dosing. BRUKINSA is also the only BTK inhibitor to demonstrate superiority to another BTK inhibitor in a Phase 3 study.

The global BRUKINSA clinical development program includes about 7,100 patients enrolled in 30 countries and regions across more than 35 trials. BRUKINSA is approved in more than 75 markets, and more than 247,000 patients have been treated globally.

Select Important Safety Information

Serious adverse reactions, including fatal events, have occurred with BRUKINSA, including hemorrhage, infections, cytopenias, second primary malignancies, cardiac arrhythmias, and hepatotoxicity (including drug-induced liver injury).

In the pooled safety population (N=1729), the most common adverse reactions (≥30%), including laboratory abnormalities, in patients who received BRUKINSA were neutrophil count decreased (51%), platelet count decreased (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%).

"The T-cell lymphomas are devastating diseases, associated with dismal outcomes, and are thus an area of high unmet need," said Ryan Wilcox, M.D., Ph.D., Associate Professor of Internal Medicine, University of Michigan Medical School. "In the relapsed/refractory setting, complete and durable responses are rarely achieved with currently available agents. The Phase 1 data demonstrate impressive progression free and overall survival in relapsed/refractory patients treated with soquelitinib. Several patients experienced complete and durable responses, some of which were maintained on therapy more than two years. For most relapsed/refractory PTCL patients, an overall survival less than 6 months is anticipated. In the phase 1 study, median progression free survival was 6.2 months and median overall survival exceeded 2 years. These results provide the foundation for the ongoing registration Phase 3 trial in relapsed/refractory peripheral T cell lymphoma."

The trial enrolled 75 patients (27 in dose escalation portion and 48 in dose expansion portion) with various T cell lymphomas, including peripheral T cell lymphoma (PTCL), T follicular helper cell lymphoma (TFHC), natural killer cell T cell lymphoma (NKTCL), cutaneous T cell lymphoma (CTCL), anaplastic large cell lymphoma (ALCL) and adult T cell lymphoma/leukemia (ATLL). The median number of prior therapies was 3 (range 1-18), with only 31% achieving an objective response to their most recent prior therapy. In the dose escalation portion, patients received a twice-daily dose of soquelitinib of 100 mg, 200 mg, 400 mg or 600 mg, and the 200 mg twice-daily dose was selected for the dose expansion portion based on biomarker studies indicating that doses of 200mg or higher achieved complete occupancy of the ITK target with the drug.

Key highlights from the data supporting the ongoing registration Phase 3 trial in relapsed/refractory PTCL include:

No dose limiting toxicities or significant adverse events were observed in any patients in all dose cohorts up to 600 mg twice-daily, including no myelosuppression or immunosuppression
Objective and durable tumor responses were seen in the 200 mg twice-daily cohort (N=36) with 6 patients experiencing complete responses
In the 200 mg twice-daily cohort, it was determined that patients with between ≥1 and ≤3 prior therapies and an adequate peripheral blood lymphocyte count (N=24) were most likely to be responders to therapy. In this patient population:
Objective responses were seen in 9 of 24 patients including 6 complete responses and 3 partial responses
Median progression free survival (PFS) was 6.2 months, including an 18-month PFS of 30%
Median overall survival (OS) was 28.1 months, including a 24-month OS of 67%

Key highlights from the data supporting soquelitinib’s mechanism of action (Th1 skewing and blocking Th2 and Th17 differentiation) and use in immune and inflammatory diseases include:

In vitro studies demonstrated that at appropriate doses, soquelitinib produces Th1 skewing, which is an immunologic property resulting from the blockade of Th2 differentiation and a shift to Th1
Biomarker studies evaluating blood samples and tumor biopsies showed an increase in Th1 in blood and tumor samples and a reduction in serum IL-5, consistent with inhibiting Th2 and Th17 cells
For 6 patients, paired tumor biopsies were compared at baseline and day 8 and showed an increase in intratumor Th1 cells with treatment analyzed using RNA sequencing

"The data presented at ASH (Free ASH Whitepaper) provides foundational information for the future development of soquelitinib and our ITK platform across oncology, immune disease and inflammation," said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. "In oncology, the data show that soquelitinib could be a new treatment option for T cell lymphomas, including in patients with advanced, aggressive disease. The data not only support our ongoing registration Phase 3 trial in PTCL, but also show immunobiological effects that demonstrate soquelitinib’s mechanism of action of affecting T cell differentiation via ITK inhibition. The mechanism operates upstream in T cell signaling pathways, which may indicate that resistance pathways are unlikely to evolve."

Dr. Miller added, "Outside of oncology, we are focused on the development of soquelitinib in atopic dermatitis and evaluating its potential in a broad range of immune and inflammatory diseases. We plan to present additional data from extension cohort 4 of our Phase 1 atopic dermatitis trial in January and initiate a Phase 2 trial in this indication in early Q1 2026."

Corvus is currently enrolling patients in a registration Phase 3 clinical trial of soquelitinib in patients with relapsed/refractory PTCL at multiple clinical sites. This randomized controlled trial is anticipated to enroll a total of 150 patients with relapsed/refractory PTCL and is evaluating soquelitinib versus physicians’ choice of either belinostat or pralatrexate. The primary endpoint of the trial is progression free survival. There are no FDA fully approved agents for the treatment of relapsed/refractory PTCL, and the FDA has granted soquelitinib Orphan Drug Designation for the treatment of T cell lymphoma and Fast Track designation for treatment of adult patients with relapsed or refractory PTCL after at least 2 lines of systemic therapy. The Company anticipates reporting interim data from the Phase 3 trial in late 2026 and completing the trial in 2027.

The ASH (Free ASH Whitepaper) oral presentation slides are available on the Publications and Presentations page of the Corvus website.

"We are delighted that our investigators can share these unprecedented Phase 1 data for TERN-701 with patient groups and the broader hematology community at ASH (Free ASH Whitepaper). The 64% major molecular response (MMR) achievement rate reported in the abstract is maintained in the expanded dataset presented at ASH (Free ASH Whitepaper). The safety profile and higher MMR achievement rate of 75% over 24 weeks at doses of 320mg and above supports selection of 320mg and 500mg QD as the recommended phase 2 doses (RP2Ds) for expansion. Study enrollment has accelerated and surpassed 85 patients which supports rapidly advancing TERN-701 through dose expansion cohorts, dose selection, and the initiation of pivotal studies," said Amy Burroughs, chief executive officer of Terns.

"We are particularly encouraged to see unprecedented rates of MMR in a highly refractory population, including compelling response achievement in patients with lack of efficacy on prior asciminib, ponatinib, and/or other marketed and investigational TKIs. In the RP2D dose range, we see a 36% DMR achievement rate by 24 weeks, highlighting the fast response kinetics of TERN-701. Importantly, with a median treatment duration of six months, we continue to see a favorable safety and tolerability profile at all doses, further positioning TERN-701 as the potential best-in-disease therapy in 2L+ and 1L CML, where we intend to focus pivotal clinical development," stated Emil Kuriakose, MD, chief medical officer of Terns.

"While therapies for CML have come a long way since imatinib, there remains an unmet need for new drugs that achieve early, broad and deep responses with a safety/tolerability profile that allows long-term maintenance of response with improved quality of life for patients. Based on the data to date, TERN-701 represents an innovative treatment option that has the potential to achieve this important goal. I am excited to help advance this therapy for the benefit of CML patients," said Dr. Jabbour.

The ASH (Free ASH Whitepaper) oral presentation today reports data from the ongoing dose escalation and dose expansion parts of the CARDINAL study of TERN-701 in patients with previously treated CML. As of the September 13, 2025 cutoff date, 63 patients were enrolled.

•
No patients had lost MMR at the time of data cutoff

•
Enrolled patients had heavily pretreated, refractory disease:

•
Median of 3 prior TKIs; 60% had ≥3 prior TKIs

•
57% and 44% had baseline BCR::ABL1 >1% and >10%, respectively

•
64% discontinued their last TKI due to lack of efficacy

•
38% had prior asciminib treatment (75% had lack of efficacy and 25% had lack of tolerability)

•
22% had prior ponatinib treatment (79% had lack of efficacy and 21% had lack of tolerability)

•
15% with BCR::ABL1 mutations (10% with T315I and 5% with non-T315I mutations)

•
Encouraging safety profile:

•
87% (55/63) of patients remained on treatment as of the data cutoff; with discontinuations due to disease progression (n=4), adverse events (n=1), and physician / patient decision or lost to follow up (n=3)

•
No dose-limiting toxicities (DLTs) were observed in dose escalation, and a maximum tolerated dose (MTD) was not reached

•
The majority of treatment-emergent adverse events (TEAEs) were low grade with no apparent dose relationship

•
Rates of cytopenia were generally low with less than 10% Grade 3 thrombocytopenia and neutropenia

•
Most common non-hematologic TEAEs were diarrhea (21%), headache (19%) and nausea (19%), all Grade 1 or 2

•
Grade 3 or higher TEAEs were all less than 10%, most commonly neutropenia (8%) and thrombocytopenia (8%)

•
TERN-701 exposures were approximately dose proportional across the dose range

•
Encouraging MMR achievement rates in patients with lack of efficacy to prior asciminib:

Subgroup Baseline Characteristics MMR achieved by 24 weeks 
Prior asciminib (n=10) No MMR at baseline 7/10 (70%)   3/7 (43%)
Prior lack of efficacy 6/7 (86%) 2/6 (33%)
Prior intolerance only 1/7 (14%) 1/1 (100%)
Assessment of patient cohorts at doses ≥ 320mg QD (n=53)

•
Similar overall baseline characteristics to the full study population:

•
Median of 3 prior TKIs

•
56% and 47% had baseline BCR::ABL1 >1% and >10%, respectively

•
38% had prior asciminib treatment, 21% had prior ponatinib treatment

•
68% discontinued their last TKI due to efficacy

•
In 30 efficacy evaluable patients, overall MMR rate of 80% (24/30) by 24 weeks, with 75% (18/24) achieving MMR and 100% maintaining MMR (6/6)

•
DMR achievement rate by 24 weeks of 36% (10/28)

•

About TERN-701 and CARDINAL Clinical Trial

TERN-701 is currently being evaluated in the CARDINAL trial (NCT06163430), a global multi-center dose escalation and dose-expansion clinical trial to assess safety, tolerability and efficacy in patients with previously treated chronic phase CML. The dose escalation portion of the CARDINAL trial completed in January 2025 with no DLTs observed up to the maximum dose of 500mg QD. Terns initiated the dose expansion portion of the trial in April 2025 with patients randomized to one of two dose cohorts (320mg or 500mg QD) with up to 40 patients per arm.
