On June 3, 2026 Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) to VS-7375, an oral and potential best-in-class investigational selective KRAS G12D (ON/OFF) inhibitor, for the treatment of adult patients with KRAS G12D-mutated unresectable locally advanced or metastatic non-small cell lung cancer (NSCLC) who have received platinum-based chemotherapy and an anti-PD-(L)1 antibody either concurrently or sequentially. FDA Fast Track Designation was previously granted for VS-7375 for the treatment of KRAS G12D-mutated advanced or metastatic pancreatic cancer.

"Non-small cell lung cancer is the most prevalent lung disease with more than 8,000 patients in the U.S. diagnosed each year with KRAS G12D-mutations. Receiving Fast Track designation for VS-7375 reinforces both the significant unmet need and the potential of VS-7375 to improve outcomes for patients with KRAS G12D-mutated lung cancer," said Michael Kauffman, M.D., Ph.D., president of development at Verastem Oncology. "We are continuing to accelerate the development of VS-7375 across multiple KRAS G12D-driven tumor types, including pancreatic, non-small cell lung, and colorectal cancers to bring a highly targeted, oral treatment option to patients as quickly as possible."

Non-small cell lung cancer (NSCLC) is the most prevalent type of lung cancer, accounting for approximately 80% to 85% of all cases. The majority of patients with NSCLC are diagnosed with advanced-stage disease, either locally advanced (30% to 35%) or metastatic (50% to 55%), which is inoperable. The KRAS G12D mutation occurs in five percent of NSCLC cases and patients with these mutations are known to have reduced responses to standard therapies and poor prognosis. Currently, no therapies are approved by the FDA specifically targeting KRAS G12D mutations in cancer.

TARGET-D 202 is a Phase 2, open-label, multi-center study to evaluate VS-7375 900 mg oral dose once daily (QD) in patients with advanced NSCLC who have received one to two prior lines of therapy. Based on positive data in pre-clinical intracranial tumor models, the study is also evaluating VS-7375 in NSCLC patients with asymptomatic untreated brain metastases.

In June 2025, Verastem initiated TARGET-D 101, its Phase 1/2 dose escalation, dose expansion and combination clinical trial evaluating VS-7375 in patients with advanced KRAS G12D-mutated solid tumors, including pancreatic, non-small cell lung, and colorectal cancers. Enrollment is ongoing with monotherapy dose escalation progressing from 400 mg through 900 mg once daily (QD) doses without dose-limiting toxicities or major safety concerns observed to date. The study is currently evaluating a 1200 mg QD monotherapy dose and a 900 mg QD cetuximab combination cohort.

In the ongoing TARGET-D 101 study, data reported in March 2026 from 23 patients treated across the 400 mg, 600 mg and 900 mg QD dose levels, with a mean treatment duration of 1.6 months (range 0.7–5.6), showed VS-7375 was generally well tolerated, with no drug-related liver function test abnormalities or Grade >2 neutropenia observed as of the January 30, 2026 data cutoff, and lower reported rates of nausea, vomiting and diarrhea compared with data previously reported in China. Following feedback from the FDA, Verastem has further expanded the VS-7375 clinical program with the initiation of three Phase 2 registration-directed trials: TARGET-D 201 in metastatic pancreatic ductal adenocarcinoma, TARGET-D 202 in advanced non-small cell lung cancer, and TARGET-D 203 in metastatic colorectal cancer.

About KRAS G12D

KRAS G12D represents 26% of all KRAS mutations, making it the most prevalent KRAS mutation in human cancers. The KRAS G12D mutation occurs most commonly in pancreatic (37%), colorectal (12.5%), endometrial (8%), biliary tract (7-15%), and non-small cell lung (5%) cancers. Currently, no therapies are approved by the U.S. Food and Drug Administration (FDA) specifically targeting KRAS G12D mutations in cancer.

About VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor

VS-7375 is a potential best-in-class, potent, and selective oral KRAS G12D dual ON/OFF inhibitor. The mechanism of action of VS-7375 is unique in that it binds the active (ON) and inactive (OFF) states of KRAS G12D, with the potential to inhibit KRAS G12D signaling and tumor growth more completely than compounds that block KRAS G12D only in the OFF state or only in the ON state.

In June 2025, Verastem initiated TARGET-D 101, a Phase 1/2 dose escalation, dose expansion, and combination clinical trial evaluating the safety and efficacy of VS-7375 in patients with advanced KRAS G12D mutant solid tumors. Verastem has further expanded the VS-7375 clinical program with the initiation of three Phase 2 registration-directed, open-label clinical trials: TARGET-D 201 in second-line advanced or metastatic pancreatic ductal carcinoma, TARGET-D 202 in second/third-line advanced or metastatic non-small cell lung cancer, and TARGET-D 203 in metastatic colorectal cancer.

In July 2025, U.S. Food and Drug Administration (FDA) granted Fast Track Designation (FTD) to VS-7375 for the first-line treatment of patients with KRAS G12D-mutated locally advanced or metastatic adenocarcinoma of the pancreas and for the treatment of patients with KRAS G12D-mutated locally advanced or metastatic pancreatic ductal carcinoma who have received at least one prior line of standard systemic therapy.

In December 2023, Verastem selected VS-7375 as its lead program from its collaboration with GenFleet Therapeutics, which aims to advance three oncology discovery programs related to RAS/MAPK pathway-driven cancers. The collaboration provides Verastem with an exclusive option to obtain a license for each of the three compounds in the collaboration after the successful completion of pre-determined milestones in a Phase 1 trial. In January 2025, Verastem exercised its license for VS-7375. The licenses would give Verastem development and commercialization rights outside the GenFleet markets of mainland China, Hong Kong, Macau, and Taiwan. GenFleet is developing VS-7375 as GFH375 in China.

On June 3, 2026 Taiho Oncology, Inc., a company developing and commercializing novel treatments for hematologic malignancies and solid tumors, reported the publication in the New England Journal of Medicine of results from the ASCERTAIN-V Phase 1/2 clinical trial, which evaluated the first all-oral regimen of decitabine-cedazuridine plus venetoclax in patients with newly diagnosed acute myeloid leukemia (AML) who are ineligible for intensive induction chemotherapy. The study demonstrated favorable response rates and survival with expected myelosuppressive effects.1

Previously presented at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting and the 2025 European Hematology Association (EHA) (Free EHA Whitepaper) Congress, the results suggest this first all-oral regimen may provide outcomes consistent with existing hypomethylating agent–venetoclax–based approaches for patients with newly diagnosed AML who cannot receive intensive induction therapy.

Nearly 23,000 people in the U.S. are expected to be diagnosed with AML, a cancer of the blood and bone marrow, in 2026. 2 More than half of those patients will likely be deemed ineligible for intensive induction chemotherapy because of factors such as older age (75 or older) or poor health. 3 For these patients, the standard treatment often combines oral venetoclax with parenteral hypomethylating agents, requiring frequent injections or infusions and an average of 12.9 days per month engaging in healthcare visits. 4

Oral decitabine-cedazuridine is a hypomethylating agent that has demonstrated oral bioavailability and equivalent pharmacokinetic exposure to intravenous decitabine. 5

"We are committed to advancing therapies that improve the lives of patients, their families and their caregivers," said Harold Keer, MD, PhD, Chief Medical Officer, Taiho Oncology. "An all-oral regimen for AML could help reduce the significant time and cost burden associated with treatment in hospitals or infusion centers."

The ASCERTAIN-V trial evaluated the first all-oral regimen of oral decitabine-cedazuridine plus venetoclax in 189 patients (Phase 1, n=30; Phase 2a, n=58; Phase 2b, n=101). After an initial ramp-up period, patients were treated in 28-day cycles, receiving decitabine-cedazuridine on days one through five and venetoclax daily. Key results include complete response rates, durable remissions and survival, and a safety profile consistent with hypomethylating agent-venetoclax regimens.

In the Phase 2b of ASCERTAIN-V:
The complete response rate was achieved in 47% of patients (95% CI: 36-57%). The composite of complete response or complete response with incomplete hematologic recovery was 63% (95% CI: 53-73%).
The median time to marrow blasts of less than 5% was 28 days (range 22 to 57), and the median time to a complete response or complete response with incomplete hematologic recovery was 35 days (range 27 to 58).
Among patients achieving complete response, 80% (95% CI: 64%, 90%) had an ongoing response at six months and 75% (95% CI: 57%, 87%) at 12 months.
Median overall survival was 15.5 months (95% CI 7.6-not estimable). The 30- and 60-day mortality rates were 3% and 10%, respectively. The median follow-up period was 11.2 months.
Serious adverse events were reported in 84% of patients, consistent with known hypomethylating agent–venetoclax regimens. Common related Grade ≥3 adverse events were anemia (30%), neutropenia (26%) and febrile neutropenia (25%).

No drug–drug interactions were observed between decitabine-cedazuridine and venetoclax.
In the Phase 2b of ASCERTAIN-V, decitabine-cedazuridine and venetoclax dosing was modified once leukemic blast clearance was achieved as measured by bone marrow morphology assessments. Serious adverse events and febrile neutropenia decreased as venetoclax dosing days decreased with each treatment cycle. This information potentially supports the need to explore a treatment strategy of an initial induction followed by dose-adjusting ongoing cycles to enhance tolerability and minimize cytopenia-related complications in patients who have reached remission.

"The positive results of the trial — response rates, safety, pharmacokinetics and tolerability data — suggest that an all-oral regimen could potentially become a meaningful alternative to existing treatment protocols that involve parenteral hypomethylating agents for patients with AML who can’t undergo intensive induction chemotherapy," said Gail J. Roboz, M.D., the paper’s lead author, a professor of medicine, director of the Clinical and Translational Leukemia Program and a member of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine and a hematologist oncologist at NewYork-Presbyterian/Weill Cornell Medical Center in New York City. "An all-oral treatment regimen is a highly anticipated addition to current treatment options for patients with AML."

About Decitabine and Cedazuridine Fixed-Dose Combination
This product is an orally administered, fixed dose combination of the approved anti-cancer DNA hypomethylating agent, decitabine, together with cedazuridine,6 an inhibitor of cytidine deaminase.7 By inhibiting cytidine deaminase in the gut and the liver, the fixed dose combination is designed to allow for oral delivery of decitabine over five days in a given cycle to achieve comparable systemic exposure to IV decitabine administered over five days.

On June 3, 2026 ADC Therapeutics SA (NYSE: ADCT) reported topline data from its Phase 3 LOTIS-5 confirmatory trial evaluating ZYNLONTA (loncastuximab tesirine-lpyl) in combination with rituximab in patients with relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL). ZYNLONTA plus rituximab achieved statistical significance on the trial’s primary endpoint of progression-free survival (PFS) and demonstrated no detrimental effect on the key secondary efficacy endpoint of overall survival (OS). In addition, a higher complete response (CR) rate and duration of CRs (DoCR) were observed with ZYNLONTA plus rituximab. Overall, treatment emergent adverse event (TEAE) rates were similar between arms. Similar rates of overall Grade ≥3 TEAEs greater than 5% were observed across both arms, with hematologic TEAEs higher in the control arm and infection, hepatotoxicity, and edema/effusion higher in the test arm. Serious adverse events (SAEs), TEAEs leading to study drug withdrawal, and Grade 5 events were higher in the test arm, with the majority of Grade 5 TEAEs in the test arm occurring in patients aged 75 years or older.

"In the context of a positive study, based on the totality of the data, we plan to discuss the benefit-risk profile of this combination with the U.S. FDA as we prepare for the planned supplemental Biologics License Application (sBLA) filing," said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. "We would like to extend our thanks to the patients, investigators, and clinical teams who contributed to this important trial."

The LOTIS-5 trial is a randomized, open‐label, two‐arm, multicenter study evaluating ZYNLONTA plus rituximab versus the standard immunochemotherapy rituximab gemcitabine‐oxaliplatin (R‐GemOx), for the treatment of r/r DLBCL after one or more lines of systemic therapy. The study met the primary endpoint of PFS (per independent review committee) with statistical significance (HR = 0.73; p-value = 0.008 two sided), with a median PFS of 6.1 months for ZYNLONTA plus rituximab vs 4.7 months for R-GemOx. Overall survival showed no detrimental effect with ZYNLONTA plus rituximab compared to the control arm (HR = 0.96, impacted by the earlier use and a higher rate of new anti-lymphoma treatment switching in the control arm). Overall response rate (ORR) was 58.1% vs. 45.2%, CR rate was 39.5% vs. 26.7%, median duration of response (DOR) was 9.2 months vs. 7.7 months, and median DoCR was 16.8 months vs. 12.3 months for ZYNLONTA plus rituximab compared to R-GemOx, respectively. Of patients achieving CR, 48.5% vs. 16.7% remained in CR at 24 months in favor of ZYNLONTA plus rituximab. Of note, results in North America were consistent with the overall study results.

Overall, TEAE rates were similar between arms (98.5% vs. 97.5%). Higher rates of SAEs were seen in the test arm (49.0% vs. 34.5%). Grade ≥3 TEAEs observed in > 5% of patients were hematologic (40.7% vs. 59.4%), followed by infection/infestations (24.5% vs. 15.7%), then hepatotoxicity (17.2% vs. 8.1%) and oedema/effusion (7.4% vs. 0.5%) when comparing ZYNLONTA plus rituximab to R-GemOx. A higher rate of Grade 5 TEAEs was observed in the ZYNLONTA plus rituximab arm (27 pts/13.2%) vs. R-GemOx (9 pts/4.6%). Of note, the majority of Grade 5 TEAEs in the test arm occurred in patients aged 75 years or older. Higher rates of TEAEs leading to any drug withdrawal occurred in the ZYNLONTA plus rituximab arm (25.5% vs. 9.1%). In this study, the TEAE reporting window was defined as 105 days after the last dose of study treatment or the start of new anticancer therapy, whichever is earlier. The rates of TEAEs in this study were impacted by the longer overall TEAE observation time in the test vs. control arm. This difference is primarily driven by a higher rate of and earlier switching to subsequent therapies in the control arm.

"LOTIS-5 was designed to address a clear unmet need in r/r DLBCL in patients who cannot access or who progress on a CAR-T or other complex therapies," said Mehdi Hamadani, MD, Professor of Medicine, Associate Director of Clinical Research, Section Chief of Hematologic Malignancies at Medical College of Wisconsin and principal investigator for the trial. "Based on these results, I believe this combination may provide an additional option in treating relapsed or refractory DLBCL."

"Based on these topline results from LOTIS-5, we look forward to discussing next steps for this combination of ZYNLONTA plus rituximab with the U.S. FDA," said Mohamed Zaki, MD, PhD, Chief Medical Officer of ADC Therapeutics. "We intend to conduct a pre-sBLA meeting in August and are preparing for a planned sBLA submission in the fourth quarter of 2026."

In addition, the Company will continue to evaluate a broad range of value maximizing alternatives, including but not limited to near-term cost reduction initiatives.

The funding will scale development of Ingenix’s Biological Reasoning Engine and broaden its work with pharma and biotech partners through the Qualified Access Program, launching today.

The dominant approach in AI for drug development, which trains larger models on larger datasets assuming biology will yield to scale, faces a structural problem. Biology is profoundly complex, fundamentally non-linguistic, and runs across modalities and biological scales. No single model, however large, can capture that on its own. Moreover, no single company holds all the data, across every modality and biological scale, to train one. Ingenix has built a different architecture, Modality Fusion, which integrates best-in-class models across modalities and biological scales, then reasons across their representations directly. The Biological Reasoning Engine is what Modality Fusion enables.

"This funding lets us extend the Biological Reasoning Engine to the partners and questions where it can do the most useful work," said Piotr Surma, CEO and co-founder of Ingenix. "We built Ingenix on the conviction that biology needs an AI architecture designed for biology and not a general-purpose model retrofitted to it. The early results have been stronger than we forecast, and we’re excited to extend the Engine to a select number of partners through the Qualified Access Program."

"It is no longer enough to just build models," added Simon Turner, Partner at Sofinnova Partners. "Ingenix is building the reasoning layer, the part that actually connects the biology, the chemistry, and the clinical data into something a scientist can interrogate and act on. That’s the hard bit, and that’s where the value compounds. We’re thrilled to back a team that gets that."

The Engine in Action: ADC Payload Prioritization

In a recent engagement, Ingenix applied its Biological Reasoning Engine to a dual-payload ADC prioritization problem for an oncology biotech which had thousands of possible payload configurations but lacked the experimental capacity to test them.

The Engine produced 15 candidate combinations. Under blind expert review by the biotech’s translational science team, the predictions broke down as follows:

5 were publicly known hypotheses.
2 were supported in existing literature but not widely cited.
3 had been confirmed by the biotech through internal experiments but never published and never disclosed to Ingenix.
5 were novel hypotheses not previously considered by the biotech team. Of these, the biotech flagged 3 as actionable candidates.
The double-payload ADC space is too new for any AI system to have seen meaningful training data on it. The engine reached its predictions by reasoning from first principles about the underlying biology, rather than by pattern-matching against prior examples.

In short, insights that had taken the biotech several years of research and millions of euros to develop were accomplished by the Engine in a matter of minutes.

Applications to the Qualified Access Program are now open at ingenix.ai/qap.

On June 3, 2026 IDEAYA Biosciences, Inc. (NASDAQ: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, reported it has entered into a clinical collaboration with Roche to evaluate the efficacy and safety of IDE892, its investigational, potential best-in-class PRMT5 inhibitor, in combination with Roche’s RG6505, a pan-RAS inhibitor, in patients with pancreatic ductal adenocarcinoma (PDAC) that carry an MTAP deletion. IDEAYA will sponsor the clinical trial combination study, and Roche will supply RG6505.

"We are pleased to evaluate the clinical combination of IDE892 with RG6505 in MTAP-deleted RAS-mutant PDAC," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences. "This collaboration aligns with our broader clinical strategy to evaluate rational combinations with assets in our MTAP-deletion portfolio, and there remains especially high unmet need in PDAC."

IDE892 was designed to be a potential best-in-class PRMT5 inhibitor and has demonstrated robust monotherapy regressions in MTAP-deleted preclinical models. IDEAYA is evaluating IDE892 in a Phase 1 dose escalation clinical trial in MTAP-deleted solid tumors and plans to initiate Phase 1 combination cohorts, in PDAC with RG6505 as well as in NSCLC and other solid tumors with IDE397, IDEAYA’s proprietary MAT2A inhibitor.

MTAP deletion is estimated to occur in up to 40% of PDAC and almost all MTAP-deleted PDAC harbor co-occurring RAS mutations. Combining a PRMT5 inhibitor with a pan-RAS inhibitor may have the potential to drive deeper and more durable responses for MTAP-deleted PDAC patients who currently have no approved targeted treatment options.

Under the clinical collaboration, IDEAYA and Roche each retain all commercial rights to their respective compounds, including as monotherapy and as combination therapies. There will be joint IDEAYA and Roche governance to oversee the clinical combination study. The clinical collaboration also has the ability to evaluate a combination triplet with IDE892, RG6505, and IDE397, IDEAYA’s Phase 2 MAT2A inhibitor, upon joint IDEAYA and Roche approval.
