The collaboration includes the development of these candidates as monotherapies, and also the evaluation of CR-001 in combination with CR-003 and with additional ADCs.

•In December 2025, Crescent completed a $185 million private placement with support from leading healthcare investors.
Pipeline
CR-001, PD-1 x VEGF bispecific antibody
•CR-001 is a tetravalent bispecific antibody that combines two complementary, validated mechanisms in oncology via a blockade of PD-1 and VEGF.

•In January 2026, Crescent announced that the U.S. Food and Drug Administration (FDA) cleared Crescent’s Investigational New Drug (IND) application for CR-001 for the treatment of advanced solid tumors.
•In February 2026, Crescent announced the dosing of the first patient in ASCEND, a global, open-label Phase 1/2 clinical trial evaluating CR-001 in multiple solid tumor types, including non-small cell lung cancer (NSCLC) and various gastrointestinal and gynecological cancers, in both treatment-naïve and previously treated patients. Crescent anticipates reporting proof-of-concept clinical data from the ASCEND trial in the first quarter of 2027, including initial safety, pharmacokinetics, pharmacodynamics and preliminary antitumor activity from dose escalation and backfill cohorts in first-line and previously treated patients.

•Crescent also plans to evaluate CR-001 in combination with multiple ADCs, including CR-002 and CR-003. Initiation of the first Phase 1/2 ADC combination trial with CR-001 is expected in the second half of 2026, with initial data anticipated by year-end 2027.
CR-002, topoisomerase inhibitor ADC targeting PD-L1
•CR-002 is a topoisomerase inhibitor ADC directed to PD-L1, a validated target known to have high expression in multiple solid tumors. CR-002 incorporates a PD-L1 antibody selected for high internalization to facilitate payload release in target cells and a linker designed for intracellular cleavage and high stability in circulation.
•Crescent is on track to submit an IND to the FDA for CR-002 in mid-2026 to support the initiation of a Phase 1/2 trial in solid tumors in the second half of 2026, with proof-of-concept data expected in the second half of 2027.
CR-003, topoisomerase inhibitor ADC targeting integrin beta-6
•CR-003 is a topoisomerase inhibitor ADC directed to ITGB6, which is overexpressed in many solid tumors with minimal expression in most normal tissues. CR-003 consists of an anti-ITGB6 fully human IgG1 monoclonal antibody conjugated via a stable, clinically validated cleavable linker.
•In January 2026, Kelun-Biotech received IND approval for CR-003 for the treatment of advanced solid tumors from the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) of China.
•Kelun-Biotech plans to initiate a Phase 1/2 trial of CR-003 in Greater China in the first quarter of 2026, with proof-of-concept data expected in the first quarter of 2027. A Phase 1/2 combination trial of CR-003 and CR-001 is expected to initiate in the first half of 2027, with initial data anticipated by year-end 2027.

"We are excited to collaborate with Merck on our randomized Phase 2 study to further demonstrate the potential of this combination to deliver improved clinical outcomes for these patients, who receive limited benefit from current standard of care therapies."

STK-012 is a first-in-class α/β-IL-2 receptor biased partial agonist engineered to selectively stimulate antigen-activated T cells, which are associated with potent anti-tumor activity, and avoid broad stimulation of other lymphocytes, such as natural killer (NK) cells, which are associated with IL-2 toxicity.

Under the terms of the agreement, Merck will provide its anti-PD-1 therapy, Keytruda, to be used in combination with STK-012 and standard of care chemotherapy in the SYNERGY-101 trial. SYNERGY-101 is a global, randomized Phase 2 study that has already begun enrollment, with the first patient dosed in November 2025. This study will investigate the safety and efficacy of STK-012 in combination with standard dose pembrolizumab and chemotherapy vs. the safety and efficacy of standard dose pembrolizumab and chemotherapy in patients with first-line, PD-L1 negative NSQ NSCLC. Synthekine and Merck will each retain all commercial rights to their respective compounds for use as monotherapies or in combination regimens.

"We made substantial clinical progress over the past year continuing to advance our broad portfolio of RAS(ON) inhibitors across multiple tumor types and disease settings," said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. "Our focus remains on executing high-quality clinical programs and leveraging our innovation platform to discover and develop potentially groundbreaking approaches aimed at improving outcomes for patients with RAS-addicted cancers. We expect a pivotal readout from RASolute 302 in the first half of 2026, which represents an important milestone for daraxonrasib, for patients with pancreatic cancer, and for our RAS(ON)-targeting strategy overall."

Recent Clinical Highlights

Pancreatic Ductal Adenocarcinoma (PDAC)

Daraxonrasib in PDAC

Daraxonrasib, a pioneering RAS(ON) multi-selective inhibitor, has shown an unprecedented clinical profile as monotherapy and in various combinations, including a RAS(ON) inhibitor doublet. The company is currently evaluating daraxonrasib in three randomized Phase 3 studies in PDAC:

RASolute 302: Global enrollment is complete in the randomized registrational trial evaluating daraxonrasib monotherapy in patients with second line (2L) metastatic disease. A readout is expected in the first half of 2026.
RASolute 303: Initiation is underway for the registrational trial evaluating daraxonrasib both as monotherapy and in combination with chemotherapy in patients with first line (1L) metastatic disease.
RASolute 304: Enrollment is ongoing in the registrational trial evaluating daraxonrasib monotherapy in the adjuvant setting in patients with resectable disease following surgery and conventional perioperative chemotherapy.
Zoldonrasib in PDAC

Zoldonrasib, an innovative RAS(ON) G12D-selective covalent inhibitor, has shown a highly differentiated safety and tolerability profile as monotherapy and is also being evaluated in a range of combinations.

In January, the company disclosed encouraging initial data from the combination of zoldonrasib plus FOLFIRINOX in patients with 1L metastatic PDAC. Nineteen patients were available for evaluation as of the December 1 data cutoff date. The initial safety and tolerability profile of the combination was largely consistent with the well-known profile of modified FOLFIRINOX alone, with high zoldonrasib dose intensity maintained. With a median follow-up of 3.9 months (2.7 – 8.0 months), 63% of patients achieved a partial response, either confirmed or pending confirmation. The disease control rate was 95% and most patients remained on treatment as of the data cutoff date. The company plans to share initial clinical data evaluating the combinations of zoldonrasib plus gemcitabine nab-paclitaxel and the RAS(ON) inhibitor doublet of zoldonrasib plus daraxonrasib at one or more medical meetings this year.

The company is advancing two 1L Phase 3 combination studies incorporating zoldonrasib this year:

RASolute 305: The randomized, double-blind, placebo-controlled registrational trial, evaluating zoldonrasib in combination with investigator’s choice of either gemcitabine nab-paclitaxel or modified FOLFIRINOX compared to investigator’s choice of the chemotherapies with placebo, has been initiated.
RASolute 309: The company plans to initiate, in the second half of 2026, a registrational trial evaluating the RAS(ON) inhibitor doublet combination of zoldonrasib plus daraxonrasib.
Non-Small Cell Lung Cancer (NSCLC)

Daraxonrasib in NSCLC

RASolve 301, a global, randomized Phase 3 trial evaluating daraxonrasib monotherapy in patients with previously treated NSCLC, continues enrolling patients in the U.S. and globally; the company anticipates substantially completing enrollment this year.

The company also expects to disclose its plans for advancing daraxonrasib combination therapy in 1L NSCLC this year.

Zoldonrasib in NSCLC

The company has reported highly encouraging safety/tolerability and antitumor activity with zoldonrasib in patients with previously treated NSCLC harboring a RAS G12D mutation. A zoldonrasib monotherapy expansion cohort of 2L and beyond patients has fully enrolled, and earlier this year zoldonrasib was awarded FDA Breakthrough Therapy designation in this setting, making it the company’s third RAS(ON) inhibitor to have received this distinction.

The company is preparing to initiate, in the first half of 2026, RASolve 308, a randomized, placebo-controlled Phase 3 trial of zoldonrasib in combination with standard of care as a 1L treatment for patients with metastatic RAS G12D NSCLC.

Elironrasib in NSCLC

For elironrasib, the company has reported a differentiated clinical profile in both RAS G12C inhibitor-naïve and G12C inhibitor-experienced NSCLC patients. Elironrasib has demonstrated encouraging results as monotherapy and in combination with either pembrolizumab or as part of a RAS(ON) inhibitor doublet with daraxonrasib.

The company plans to share an update on its registrational vision for elironrasib in 2026.

Colorectal Cancer (CRC)

Given the genetically complex and heterogeneous nature of colorectal cancer, the company believes combinatorial approaches are key to maximizing clinical impact. The company has a range of combination trials underway, including evaluating RAS(ON) inhibitor doublets and combinations with current standards of care and other novel investigational approaches.

The company plans to share updated combination data in CRC this year as it looks toward potential pivotal trial opportunities.

Clinical Collaborations

The company’s development efforts include several clinical collaborations studying its RAS(ON) inhibitors with other targeted therapies:

Under a collaboration with Summit Therapeutics, Inc., the APEX-103 trial is evaluating Revolution Medicines’ RAS(ON) inhibitors with ivonescimab, Summit’s PD-1/VEGF bispecific antibody, across multiple solid tumor settings. The first patient was recently dosed in this clinical trial.
A collaborative trial with Tango Therapeutics, Inc. is evaluating Revolution Medicines’ RAS(ON) inhibitors in combination with vopimetostat, Tango’s MTA-cooperative PRMT5 inhibitor, in patients with tumors carrying both a RAS mutation and MTAP deletion.
The company also recently entered into a clinical collaboration with Bristol Myers Squibb to evaluate daraxonrasib in combination with navlimetostat, Bristol Myers Squibb’s MTA-cooperative PRMT5 inhibitor, in patients with pancreatic cancer whose tumors carry both a RAS mutation and MTAP deletion. This collaboration extends Revolution Medicines’ commitment to evaluating novel targeted agents, such as PRMT5 inhibitors, that may be appropriate to combine with RAS(ON) inhibitors in some settings.
Early-Stage Programs

RMC-5127

The company recently advanced its fourth RAS(ON) inhibitor, the RAS(ON) G12V-selective inhibitor RMC-5127, into the clinic and announced that the first patient was dosed in a first-in-human trial.

The company expects to identify a recommended monotherapy Phase 2 dose for this compound in the second half of 2026.

Innovative New Class of RAS(ON) Inhibitors

The company continues to discover novel approaches that have the potential to further transform treatment paradigms for patients living with RAS-addicted cancers.

In January, the company introduced an innovative new class of RAS(ON) inhibitors designed to overcome RAS-driven acquired drug resistance and extend the clinical benefit of its RAS(ON) portfolio. A compound from this class of RAS(ON) inhibitors, RM-055, was shown to drive deep and durable tumor regressions in preclinical PDAC and NSCLC models that had developed resistance to a RAS multi-selective inhibitor.

The company plans to share more information about this new class of compounds at an upcoming scientific meeting, and plans to initiate a Phase 1 trial with the first compound from this class of RAS(ON) inhibitors in the fourth quarter of this year.
