Insights

Oral ASH slot and Phase 1 safety at 500 mg with 55 patients.

Terns reports its TERN-701 Phase 1 CARDINAL data will be presented orally at ASH. The dose-escalation phase completed with no DLTs up to 500 mg QD, and expansion is randomizing between 320 mg and 500 mg.

As of June 30, 2025, 55 patients were enrolled. The company cites consistently high cumulative MMR in hard-to-treat subgroups with an encouraging safety profile. These are early-phase signals and come from the abstract highlights.

The presentation on December 8, 2025 will provide more detail. Actual impact depends on the depth of efficacy and safety results disclosed at that session.

Item 7.01

Regulation FD Disclosure.

On November 3, 2025, Terns Pharmaceuticals, Inc. (the Company or Terns) issued a press release announcing that an abstract with updated data from the ongoing Phase 1 CARDINAL trial evaluating TERN-701 in patients with relapsed/refractory chronic myeloid leukemia (CML) has been selected for oral presentation on December 8, 2025 at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition. The press release also provides highlights of reported data as of June 30, 2025 from the abstract regarding the ongoing dose escalation and dose expansion parts of the CARDINAL trial. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1.

The information contained in Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the Exchange Act), and shall not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

 

Item 8.01

Other Events.

On November 3, 2025, Terns announced that an abstract with updated data from the ongoing Phase 1 CARDINAL trial evaluating TERN-701 in patients with relapsed/refractory CML has been selected for oral presentation on December 8, 2025 at the 67th ASH Annual Meeting and Exposition. TERN-701 is a novel investigational allosteric BCR::ABL1 inhibitor being developed for patients with CML. CARDINAL is a global, multicenter, 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 CARDINAL completed in January 2025 with no dose limiting toxicities (DLTs) observed up to the maximum dose of 500 mg once daily (QD). Terns initiated the dose expansion of the trial in April 2025, with patients randomized to one of two dose cohorts (320 mg or 500 mg QD) with up to 40 patients per arm.

As of the June 30, 2025 cutoff date, 55 patients were enrolled. Key highlights include:

 

   

Of 32 efficacy-evaluable patients:

 

   

Overall (cumulative) major molecular response (MMR) rate of 75% (24/32) by 24 weeks, with 64% (14/22) achieving MMR and 100% (10/10) maintaining MMR

 

   

Overall (cumulative) MMR by 24 weeks in difficult to treat patient subgroups:

 

 

69% (11/16) in patients with lack of efficacy to last tyrosine kinase inhibitor (TKI)

 

 

60% (6/10) in patients who had prior asciminib

 

 

67% (8/12) in patients with prior asciminib/ponatinib/investigational TKI

 

   

No patients had lost MMR at the time of data cutoff

 

   

Enrolled patients had heavily pretreated, refractory disease:

 

   

Median of 3 prior TKIs

 

   

35% had ≥ 4 prior TKIs

 

   

56% and 44% had baseline BCR::ABL1 > 1% and > 10%, respectively

 

   

64% discontinued their last TKI due to lack of efficacy

 

   

36% had prior asciminib treatment, 25% had prior ponatinib and/or an investigational TKI (olverembatinib/ELVN-001)

 

   

13% with BCR::ABL1 mutations (9% with T315I and 4% with F317L)

 

   

TERN-701 showed an encouraging safety profile:

 

   

87% (48/55) patients remained on treatment as of the data cut-off; with discontinuations due to disease progression (n=4), adverse events (n=1), and consent withdrawal/lost to follow up (n=2)

 

   

No DLTs were observed in dose escalation and a maximum tolerated dose was not reached

 

   

The majority (74%) of treatment-emergent adverse events (TEAEs) were low grade with no apparent dose relationship

 

   

Most common TEAEs were diarrhea (22%), headache (18%) and nausea (16%), all Grade 1 or 2

 

   

Grade 3 or higher TEAEs were all less than 10%, most commonly neutropenia (7%) and thrombocytopenia (4%)

 

   

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


TERN-701 achieved consistently high overall (cumulative) MMR rates in key, difficult to treat patient subgroups while maintaining an encouraging safety profile. These emerging data reinforce the Company’s belief that TERN-701 has the potential to be a best-in-disease therapy, with broad opportunity across all CML treatment lines.
