Current report

We expect to report top-line results from our SUMMIT trial in July 2025 and from our APEX trial in the second half of 2025, and we plan to submit the first bezuclastinib New Drug Application (“NDA”) by the end of 2025 for patients with SM.

Current report

In the first quarter of 2025, we initiated an expanded access program in the United States for SM patients to receive investigational bezuclastinib after meeting certain eligibility criteria.

Current report

At the 100 mg QD dose and as of the cut-off date of August 29, 2024, 89% of patients had >50% decrease in serum tryptase by four weeks of treatment with bezuclastinib and 95% of patients with elevated baseline tryptase achieved serum tryptase levels <20 ng/ml by week 24. Additionally, 84% of patients with baseline serum tryptase >11.4ng/ml achieved <11.4ng/mL by week 24.

Current report

After 24 weeks of active treatment, the 27 patients randomized to receive 100 mg QD were evaluated for signs of clinical activity using multiple PRO measures, including the Mastocytosis Symptom Severity Daily Diary (“MS2D2”) and the Mastocytosis Quality-of-Life (“MC-QoL”) scale. These patients reported at 56% mean improvement in TSS from baseline. Additionally, 76% of patients demonstrated >50% reduction from baseline in MS2D2 TSS with 88% of patients exceeding 30% reduction from baseline after 24 weeks. At 24 weeks of treatment, 31% of patients have already reduced or discontinued best supportive care (“BSC”) medications. These same patients saw a 49% mean improvement in MC-QOL Total Score at 24 weeks.

Current report

As of the data cutoff, August 29, 2024, the median duration of bezuclastinib treatment was 56 weeks for patients in the active arm and 40 weeks for placebo patients who crossed over to the OLE. The majority of treatment emergent adverse events were low grade and reversible with no treatment-related bleeding or cognitive impairment events reported. The most common treatment-emergent adverse events were hair color changes and transaminase elevations. All patients experiencing elevated transaminases were asymptomatic and elevations were reversible: five patients resolved without any dose modifications and remained on study; two patients resolved with dose reduction and remained on study, one of whom re-escalated to the original dose; and two patients resolved following discontinuation. All of the safety data were previously reported at ASH 2024. There were no other discontinuations due to adverse events.

Current report

As of the cutoff date of October 11, 2024, 32 patients enrolled were evaluated for signs of clinical activity, 27 of whom were mIWG-MRT-ECNM evaluable. An objective response rate (“ORR”) of 52% (including complete remission (“CR”), CR with partial hematologic remission (“CRh”), partial remission (“PR”), and clinical improvement (“CI”)) was achieved, including 61% ORR for TKI-treatment-naïve patients. An ORR of 88% was achieved by pure pathological response (“PPR”) criteria. The median time to achieve response was 2.2 months and median duration of response has not yet been reached. Median progression-free survival (“PFS”) was not yet reached at median follow-up of 20 months and the PFS rate at 24 months was 82%.

Current report

As of the cutoff date, 94% of patients achieved a ≥ 50% reduction in serum tryptase levels, with 100% of patients receiving at least two cycles of treatment achieving a ≥ 50% reduction and 66% of patients achieved a reduction of serum tryptase below 20 ng/ml. Additionally, 93% of KIT D816V-positive patients achieved a ≥ 50% reduction in KIT D816V VAF and 100% of evaluable patients achieved ≥ 50% reduction in bone marrow mast cell burden, with 83% of patients achieving a complete clearance of mast cell aggregates.

Current report

As of the data cutoff date, bezuclastinib continues to demonstrate a differentiated safety and tolerability profile across doses. The majority of hematological adverse events were low grade and reversible. There have been no new treatment-related serious adverse events or discontinuations reported since ASH 2023. Twelve patients required dose reduction, eight of whom were treated at a 400 mg daily dose.

Current report

In the first quarter of 2025, we initiated an expanded access program in the United States for patients affected with advanced, metastatic, and/or unresectable GIST, intolerant to imatinib or received prior imatinib therapy for treatment that resulted in disease progression, and who meet other inclusion and exclusion criteria.
Removed paragraphs (17)

Previous report

At the RP2D and as of the cut-off date of December 18, 2023, 100% of patients with baseline tryptase ≥20ng/mL achieved <20ng/mL at week 12 versus 0% of placebo patients. Additionally, 100% of patients with detectable baseline KIT D816V variant allele fraction (“VAF”) achieved ≥50% reduction in KIT D816V VAF at week 12 versus 0% of placebo patients and 86% of patients with evaluable bone marrow samples achieved ≥50% reduction in bone marrow mast cell burden at week 12 versus 40% of placebo patients.

Previous report

Patients enrolled in SUMMIT Part 1b were evaluated for signs of clinical activity over 12 weeks using multiple PRO measures, including MS2D2 and the Mast Cell Quality-of-Life (“MC-QoL”). At the RP2D, patients reported a 51% mean improvement in overall symptom severity MS2D2 TSS from baseline at week 12 for bezuclastinib 100 mg versus 18% improvement for placebo. Additionally, patients at the RP2D reported a statistically significant reduction in total symptom severity after 12 weeks when compared to placebo (-23.78 vs. -9.03; p=0.0003) and 70% of patients at the RP2D achieved ≥50% reduction in MS2D2 TSS at Week 12 versus 8% placebo patients. Patients at the RP2D reported a 49% mean improvement in quality of life (MC-QoL) versus 24% for placebo. Additionally, patients at the RP2D reported a statistically significant improvement in quality of life after 12 weeks when compared to placebo (–24.86 vs. -12.39, p=0.046).

Previous report

The majority of treatment emergent adverse events were low grade and reversible with no bleeding or cognitive impairment events reported across cohorts. There were no dose reductions in the 100 mg cohort and two dose reductions in the 150 mg cohort (Grade 1 ALT and Grade 2 abdominal pain). Only one serious adverse event (“SAE”) was reported across both cohorts, which occurred in the 150mg cohort, when a patient experienced ALT/AST increase that led to discontinuation. SUMMIT Part 2 is currently ongoing using the RP2D.

Previous report

In June 2024, we presented additional data from SUMMIT Part 1 at the 2024 European Hematology Association (“EHA”) Congress. As of the cutoff date, December 18, 2023, patients in Part 1 treated at the recommended dose of 100 mg bezuclastinib demonstrated >90% reductions across all markers of mast cell burden. Additional data also show meaningful reduction in symptom severity and objective measures of disease, including a substantial reduction in mast cell reactions (>50%) and patients’ most severe symptoms as measured by MS2D2, clinically meaningful reduction in all individual MS2D2 TSS symptoms and across domains, as well as additional symptoms including dizziness, diarrhea severity, and brain fog, and clinically meaningful improvement in skin symptoms as well as objective reduction in skin lesions. Consistent with results previously reported, as of the December 18, 2023 cutoff date, the RP2D demonstrates a favorable safety and tolerability profile. There were no bleeding or cognitive impairment adverse events reported and no SAEs reported.

Previous report

Certain of our direct research and development expenses are tracked on a program-by-program basis and consist of costs, such as fees paid to consultants, contractors, CMOs, and CROs in connection with our discovery, preclinical and clinical development activities. We do not allocate employee costs, costs associated with the manufacture of bezuclastinib, costs associated with our discovery efforts, laboratory supplies, and facilities, including depreciation or other indirect costs, to specific product development programs because these costs are deployed across multiple product development programs and, as such, are not separately classified.

Previous report

This consists of changes in the fair value of the contingent value right (“CVR”) liability.

Previous report

Comparison of the nine months ended September 30, 2024 and 2023

Previous report

Total research and development expense increased by $45.6 million for the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023, driven by higher external research and development costs associated with the manufacture and development of bezuclastinib, including costs associated with the APEX, SUMMIT and PEAK trials, and the continued development and progression of our research pipeline. Additionally, there was an increase in unallocated expenses driven by higher personnel costs due to an increase in headcount, including stock-based compensation expense which increased by $3.4 million for the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023.

Previous report

General and administrative expenses for the nine months ended September 30, 2024 were $31.6 million, compared to $24.9 million for the nine months ended September 30, 2023. The increase in general and administrative expenses was primarily due to higher personnel costs driven by an increase in headcount, including stock-based compensation expense which increased by $4.6 million for the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023, and initial commercial readiness activities initiated in the third quarter of 2024.

Previous report

Interest income for the nine months ended September 30, 2024 was $14.2 million, compared to $9.2 million for the nine months ended September 30, 2023. The increase is due to higher average invested balances in cash equivalents and marketable securities.

Previous report

Other income, net for the nine months ended September 30, 2024 was less than $0.1 million, compared to $1.0 million for the nine months ended September 30, 2023. For the nine months ended September 30, 2024, other income represented miscellaneous income while for the nine months ended September 30, 2023, other income primarily represented sublease income recognized resulting from the sublease of a portion of our former corporate headquarters space. The decrease in other income, net is driven by the expiration of our former corporate headquarters lease and associated sublease in April 2023.

Previous report

The change in fair value of CVR liability for the nine months ended September 30, 2024 was nil, compared to $1.7 million for the nine months ended September 30, 2023. We recorded a decrease in fair value of the liability of $1.7 million in the first quarter of 2023, reducing the liability to zero as the probability of additional CVR payments occurring prior to the expiration of CVR term was remote. The CVRs expired on August 6, 2023 and no further payments will be made to CVR holders.

Previous report

On May 6, 2022, we filed a shelf registration statement on Form S-3 with the SEC. The shelf registration statement allows us to sell from time-to-time up to $300.0 million of common stock, preferred stock, debt securities, warrants or units comprised of any combination of these securities, for our own account in one or more offerings. The terms of any offering under the shelf registration statement will be established at the time of such offering and will be described in a prospectus supplement filed with the SEC prior to the completion of any such offering.

Previous report

On June 13, 2022, we completed an underwritten public offering of 17,899,698 shares of our common stock at a public offering price of $8.25 per share (including the exercise in full by the underwriters of their 30-day option to purchase up to 2,730,000 additional shares of common stock) and, in lieu of common stock to certain investors, pre-funded warrants to purchase 3,030,302 shares of our common stock at a purchase price of $8.24 per underlying share. The net proceeds from the offering were approximately $161.9 million, after deducting the underwriting discounts and commissions and estimated offering expenses.

Previous report

In June 2023, we completed an underwritten public offering of 14,375,000 shares of our common stock at a public offering price of $12.00 per share (including the exercise in full by the underwriters of their 30-day option to purchase up to 1,875,000 additional shares of common stock). The net proceeds from the offering were approximately $161.8 million, after deducting the underwriting discounts and commissions and offering expenses.
Reworded paragraphs (40)

Previous wording

We are a clinical-stage biotechnology company focused on developing precision therapies for genetically defined diseases. Our approach is to design rational precision therapies that treat the underlying cause of disease and improve the lives of patients. Our most advanced program is bezuclastinib, also known as CGT9486, a highly selective tyrosine kinase inhibitor that is designed to potently inhibit the KIT D816V mutation as well as other mutations in KIT exon 17. In the vast majority of cases, KIT D816V is responsible for driving Systemic Mastocytosis (“SM”), a serious and rare disease caused by unchecked proliferation of mast cells. Exon 17 mutations are also found in patients with advanced gastrointestinal stromal tumors (“GIST”), a type of cancer with strong dependence on oncogenic KIT signaling. Bezuclastinib is a highly selective and potent KIT inhibitor with the potential to provide a new treatment option for these patient populations. We are developing bezuclastinib in patients living with Advanced Systemic Mastocytosis (“AdvSM”), Non-Advanced Systemic Mastocytosis (“Non-AdvSM”) and GIST. In addition to bezuclastinib, the Cogent Research Team is developing a portfolio of novel targeted therapies to help patients fighting serious, genetically driven diseases initially targeting mutations in FGFR2, ErbB2, PI3Kα and KRAS.

Previous wording

The vast majority of AdvSM and Non-AdvSM patients have a KIT D816V mutation. Patients with AdvSM have a significantly diminished lifespan with a median survival of less than 3.5 years. For patients with Non-AdvSM, while their lifespan is not impacted by the disease, these patients suffer from a poor quality of life and new treatment options are badly needed. The FDA has granted orphan drug designation to bezuclastinib for the treatment of Mastocytosis.

Previous wording

SUMMIT is our randomized, global, multicenter, double-blind, placebo-controlled, multi-part Phase 2 clinical trial for patients with Non-AdvSM. The study is designed to explore the safety and efficacy of bezuclastinib in patients with moderate to severe Non-AdvSM, which includes Indolent Systemic Mastocytosis (“ISM”), Smoldering Systemic Mastocytosis (“SSM”) and Bone Marrow Mastocytosis. SUMMIT Part 1 completed enrollment in the third quarter of 2023, including over enrollment at 54 patients across Part 1a and Part 1b. SUMMIT Part 2 is a registration-directed study that is currently enrolling and expected to include 159 patients.

The study is designed to explore the safety and efficacy of bezuclastinib in patients with moderate to severe Non-AdvSM, which includes Indolent Systemic Mastocytosis (“ISM”), Smoldering Systemic Mastocytosis (“SSM”) and Bone Marrow Mastocytosis. Based on the performance of bezuclastinib’s optimized formulation in the PEAK lead-in trial, as well as in a healthy normal volunteer study, the SUMMIT trial protocol was amended to allow for the optimized formulation to be introduced during the Phase 1b dose optimization phase. SUMMIT Part 1 completed enrollment in the third quarter of 2023, including over enrollment at 54 patients across Part 1a and Part 1b. SUMMIT Part 2 completed enrollment in the fourth quarter of 2024, including over enrollment at 179 patients. We expect to report top-line results in July 2025.

Previous wording

From the data collected in Part 1 of SUMMIT and in accordance with FDA guidelines, we have developed a novel patient reported outcomes measure (“PROM”) called Mastocytosis Symptom Severity Daily Diary (“MS2D2”). Based on literature review, patient and physician interviews, and data from SUMMIT Part 1, we believe our MS2D2 is a reliable, valid and fit-for-purpose PROM. The MS2D2 Total Symptom Score (“TSS”) is comprised of 11 items, and scored on a 0-110 scale. We expect that a comparison of week 24 mean absolute change from baseline in MS2D2 TSS between bezuclastinib and placebo will serve as the measurement of the primary endpoint of the SUMMIT Part 2 study. In June 2024, we announced a positive discussion with the FDA and that we reached alignment with the FDA on the use of MS2D2 in Part 2 of SUMMIT. We expect to complete enrollment in SUMMIT Part 2 in the first quarter of 2025, with top-line results expected in the second half of 2025.

Previous wording

In February 2024, we presented data from SUMMIT Part 1b at the 2024 American Academy of Allergy, Asthma and Immunology (“AAAAI”). Thirty four patients were enrolled in Part 1b and were treated with either bezuclastinib or placebo plus best supportive care. Patients were enrolled with the following sub-types: 33 patients with ISM and one patient with SSM. One patient had received prior avapritinib. These patients were evaluated for signs of clinical activity over 12 weeks, including well-accepted biomarkers of disease burden. Based on the totality of the results from SUMMIT Part 1, the data support 100 mg QD as the optimal dose of bezuclastinib in Part 2 of SUMMIT for patients with Non-AdvSM (“RP2D”).

Based on the totality of the results from SUMMIT Part 1, the data support 100 mg QD as the optimal dose of bezuclastinib in Part 2 of SUMMIT for patients with Non-AdvSM. After the initial 12-week period, all patients were given the opportunity to receive bezuclastinib in the SUMMIT Open Label Extension (“OLE”). In December 2024 at the 2024 American Society of Hematology (“ASH”) Annual Meeting, we presented updated data on the 27 patients who were randomized in either Part 1 or the OLE to receive the 100 mg QD dose.

Previous wording

APEX is our global, open-label, multi-center, Phase 2 clinical trial in patients with AdvSM evaluating the safety, efficacy, pharmacokinetic, and pharmacodynamic profiles of bezuclastinib. In June 2022, we reported positive interim clinical data from Part 1 of the APEX trial at the 2022 EHA Congress, and we presented updated positive clinical data from Part 1 in an oral presentation at the American Society of Hematology (“ASH”) Annual Meeting in December 2022. In April 2023, we initiated the registration-directed Part 2 of the APEX trial at 150 mg daily dose of bezuclastinib. We remain on track to deliver top-line results from the APEX trial by mid-2025.

Current wording

APEX is our registration-directed global, open-label, multi-center, Phase 2 clinical trial in patients with AdvSM evaluating the safety, efficacy, pharmacokinetic, and pharmacodynamic profiles of bezuclastinib. In April 2023, we initiated Part 2 of the APEX trial using the optimized formulation of bezuclastinib at 150 mg daily dose. An additional APEX cohort was initiated in the third quarter of 2023 and is designed to allow concomitant administration of bezuclastinib with azacitadine in patients with SM-AHN. We completed enrollment in APEX Part 2 in the first quarter of 2025 with 58 patients and expect to present top-line results in the second half of 2025.

Previous wording

In December 2023, at the 2023 ASH meeting, we reported additional positive clinical data from Part 1 of the APEX trial. As of the data cutoff date of September 25, 2023, 32 patients had been treated in Part 1 at one of four dose levels of the original formulation (50 mg BID, 100 mg BID, 200 mg BID or 400 mg QD). Patients were enrolled with the following sub-types: seven patients with ASM, 23 patients with SM-AHN, and two patients with MCL. As of the cut-off date of September 25, 2023, 32 patients enrolled were evaluated for signs of clinical activity and 27 patients were evaluable for response per the modified IWG-MRT-ECNM criteria. An objective response rate ("ORR") of 52% (including complete remission (“CR”), CR with partial hematologic remission (“CRh”), partial remission (“PR”)) was achieved, including a 56% ORR for TKI-treatment-naïve patients. An ORR of 75% was achieved by pure pathological response (“PPR”) criteria, including an ORR of 86% for TKI-treatment-naïve patients. All patients receiving the 100mg BID achieved PR or better and remain on trial with 3 patients at ≥ 30 cycles of treatment. The 150mg QD dose of our optimized formulation selected for APEX Part 2 is expected to deliver patient exposures consistent with the 100mg BID dose of the original formulation used in Part 1. An additional APEX cohort was also initiated in the third quarter of 2023 and is designed to allow concomitant administration of bezuclastinib with azacitadine in patients with SM with an associated hematologic neoplasm.

Current wording

In December 2024, at the 2024 ASH meeting, we reported updated positive clinical data from Part 1 of the APEX trial. Thirty-two patients were treated in Part 1 at one of four dose levels (50 mg BID, 100 mg BID, 200 mg BID or 400 mg QD). In 2024, we announced APEX Part 2 would be conducted at the optimized 150mg QD dose, which closely matches the exposure from 100 mg BID dose in APEX Part 1. Patients were enrolled with the following sub-types: seven patients with aggressive systemic mastocytosis (“ASM”), 23 patients with systemic mastocytosis with associated hematologic neoplasm (“SM-AHN”), and two patients with mast cell leukemia (“MCL”).

Previous wording

PEAK is our randomized open-label, global Phase 3 clinical trial designed to evaluate the safety, tolerability, and efficacy of bezuclastinib in combination with sunitinib compared to sunitinib alone in patients with locally advanced, unresectable or metastatic GIST who have received prior treatment with imatinib. The FDA and EMA have granted orphan drug designation to bezuclastinib for the treatment of GIST. Patient enrollment for the pivotal portion of the PEAK trial was completed in the third quarter of 2024. Based on strong global patient interest, a total of 413 patients were enrolled in the trial. In addition, we completed a pre-planned interim futility analysis, and the Independent Data Monitoring Committee (“IDMC”) recommended continuing the PEAK study without modification. This pre-specified analysis was based on an assessment of progression-free survival (“PFS”) as determined by independent central review and did not include the option for early stopping due to efficacy. Top line results are expected by the end of 2025.

In June 2024, we presented updated positive clinical data from the lead-in portion of PEAK Part 1 at the 2024 American Society of Clinical Oncology (“ASCO”) meeting. As of the cutoff date, April 1, 2024, the 42 patients in Part 1 have been on study for a median of 15.3 months. The median progression-free survival (“mPFS”) during treatment with bezuclastinib and sunitinib was 10.2 months in all of these heavily pre-treated GIST patients. In a subset of second-line GIST patients with only prior imatinib, which most closely resembles patients currently enrolling in the Phase 3 registration-enabling PEAK study, the data demonstrate a mPFS of 19.4 months. In addition, the objective response rate (“ORR”) in all patients treated with bezuclastinib and sunitinib was 27.5% and in the subset of second-line patients the ORR was 33.3%, per investigator assessment. Combination treatment resulted in a disease control rate of 80% in all patients and 100% in second-line patients with prior imatinib only. As of the data cutoff, the combination of bezuclastinib and sunitinib does not appear to add to the severity of adverse events known to be associated with sunitinib monotherapy and is well-tolerated. The majority of treatment-emergent adverse events (“TEAEs”) were low-grade and reversible and discontinuations due to TEAEs remain limited.

Previous wording

In May 2024, we also announced the initiation of a new advanced Phase 2 clinical trial of bezuclastinib plus sunitinib in later line GIST patients that is being sponsored by the Sarcoma Alliance for Research through Collaboration and in collaboration with The Life Raft Group and Dana-Farber Cancer Institute. The open label, single arm Phase 2 trial is designed to evaluate the mPFS as well as the safety and tolerability of bezuclastinib plus sunitinib in 40 patients with GIST who have previously progressed on sunitinib. This trial is focused on later line patients that are not eligible for PEAK and have limited treatment options.

Our research team is building a pipeline of small molecule inhibitors, with our first efforts aimed toward targeting currently undrugged mutations in fibroblast growth factor receptor (“FGFR”). FGFR mutations are well-established oncogenic drivers in multiple diseases, but approved medicines fail to capture the full landscape of FGFR altered tumor types, with FGFR1-mediated hyperphosphatemia serving as the most common dose-limiting toxicity for pan-FGFR inhibitors. We have selected our FGFR2 clinical candidate, CGT4859. In April 2023, we reported preclinical data at the American Association for Cancer Research (“AACR”) 2023 Annual Meeting providing the first published evidence of CGT4859 a reversible, selective FGFR2 inhibitor with coverage of activating and emerging resistance mutations that spares inhibition of FGFR1. Preclinical data demonstrate a profile that delivers equipotent coverage across both key gatekeeper and molecular brake mutations (V564X, N549X) in FGFR2, while avoiding any evidence of FGFR1-linked hyperphosphatemia at efficacious plasma concentrations. In October 2023, we presented updated preclinical data at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. Preclinical data demonstrate a profile that exhibits low namomolar potency on WT FGFR2 and FGFR2 mutations and is selective against the kinome, as well as a panel of ion channels and receptors. Exploratory pharmacokinetics studies conducted across species showed CGT4859 to be a low-clearance compound with high oral bioavailability. Further, in a mutant-driven mouse model, CGT4859 demonstrated dose-responsive tumor growth inhibition with complete regressions at 5 mg/kg PO and was well-tolerated. In addition, as a reversible inhibitor, the Cogent program retains enzymatic potency against potential cysteine 491 mutations. We initiated a Phase 1 study of CGT4859 in patients with FGFR2 mutations, including advanced cholangiocarcinoma, in the third quarter of 2024. The trial will explore the safety, tolerability and clinical activity of escalating doses of CGT4859 with a goal of selecting an active and well tolerated dose for further clinical investigation. Preliminary results from this trial are expected in 2025.

Our research team is also advancing a novel, ErbB2 mutant program, which is focused on actionable and underserved mutations in a variety of solid tumor indications. In April 2023, we reported preclinical data at AACR describing a series of novel compounds which potently inhibit several key ErbB2 mutations, including YVMA insertions, while sparing inhibition of EGFR. An exemplar compound from these series demonstrates advantages versus tucatinib, an approved benchmark compound, on tumor growth inhibition in a peripheral ErbB2 L755S driven mutant model, as well as in an ErbB2 driven intracranial model. Recent program advances with a novel chemotype have further improved ErbB2 mutational potency and selectivity and improved human whole blood stability to nearly 24 hours, suggesting a favorable profile for optimal clinical efficacy. Updated data was presented in November 2023 at the San Antonio Breast Cancer Symposium (“SABCS”) and at AACR in April 2024. The updated data presented shows that CGT4255 demonstrated low nM potency against ErbB2 wild-type and oncogenic ErbB2 mutations with greater than 100-fold selectivity over wild-type-EGFR. In addition to impressive selectivity across a broad range of kinases, receptors and ion channels, CGT4255 has exceptional half-life in human whole blood and liver cytosol fractions. Dose ascending PK data in mice showed low clearance and high oral bioavailability at all doses, with best-in-class 80% brain penetrance at 100 mg/kg. Maximum inhibition of ErbB2 was observed at a 30 mg/kg PO dose in both NIH/3T3 ErbB2-YVMA and ErbB2-L755S tumor models, with complete regressions at 100 mg/kg PO BID in the NIH3T3 ErbB2-L755S TGI model and was well tolerated. These advances continue to highlight a favorable profile for optimal clinical efficacy. We selected our ErbB2 clinical candidate and initiated IND-enabling studies in mid-2024.

In addition, at the 2024 SABCS meeting, CGT4255 demonstrated robust efficacy in combination with T-DXd in an NCI-N87-luc Intracranial Her2+ Model, highlighting the ability to treat challenging intercranial tumors. In April of 2025 at the American Association of Cancer Research annual meeting (“AACR 2025”), we presented robust tumor growth inhibition in a mutant Her2-YVMA subcutaneous Patient Derived Xenograft model, supporting potential clinical development in HER2-YVMA lung cancer. These advances continue to highlight a favorable profile for optimal clinical efficacy. We selected our ErbB2 clinical candidate in 2024 and plan to submit an IND application in 2025.

Our research team is also developing a potential best-in-class, wild-type-sparing, PI3Kα inhibitor that provides coverage for the H1047R mutation, which affects >30,000 cancer patients each year. The phosphoinositide 3-kinase (“PI3K”) pathway is a key cell cycle regulating pathway that has an established role in tumor growth and development. PI3Kα mutations are highly prevalent in many solid tumors and are present in 36% of all breast cancer patients. The approved agents for these patients often lead to dose limitations, resulting from activity against wild-type PI3Kα. Preclinical data was presented at the 2024 EORTC-NCI-AACR International Symposium on Molecular Targets and Cancer Therapeutics (“EORTC-NCI-AACR”) in October 2024 and highlighted that CGT6297 is an allosteric inhibitor of PI3K, was well-tolerated in the tumor growth inhibition efficacy models and has been profiled based on its selectivity for H1047R over WT PI3K. CGT6297 demonstrated low nM potency in H1047R mutant PI3K cell lines, differentiated dose ascending PK in mice with high bioavailability and low clearance. CGT4824 also showed >95% inhibition of pAKT in a H1047R PD model, importantly without increases in insulin or C-peptide. Its efficacy profile was superior to a clinically-relevant dose of Alpelisib in the NCI H1048 mouse tumor growth inhibition model. CGT6297 has been selected as our clinical candidate for the PI3K 1047 mutation focused project. IND-enabling studies are expected to be initiated in 2025.
