Insights

IDEAYA Biosciences reported a strong financial position with $952.7 million in cash and equivalents as of June 30, 2024, further bolstered by $283.8 million in net proceeds from a July public offering. This substantial cash runway is expected to fund operations into at least 2028, providing significant financial stability.

However, the company's net loss widened to $52.8 million in Q2 from $39.6 million in Q1, primarily due to increased R&D expenses ($54.5 million vs $42.8 million) and G&A expenses ($10.4 million vs $8.2 million). The absence of collaboration revenue in both quarters is noteworthy, indicating a current reliance on cash reserves to fund operations.

While the increased spending reflects advancing clinical programs, investors should monitor the burn rate closely. The company's robust pipeline and potential milestone payments from partnerships could offset expenses, but profitability remains a distant goal.

IDEAYA's clinical progress is impressive, particularly in uveal melanoma and MTAP-deletion solid tumors. The darovasertib program shows promise, with triple-digit enrollment in the Phase 2/3 trial for metastatic uveal melanoma and over 50 patients in the neoadjuvant study. Interim data from the neoadjuvant trials demonstrated significant tumor shrinkage and eye preservation rates, which could be game-changing for patients.

The IDE397 program in MTAP-deletion tumors also shows potential, with a 39% overall response rate in urothelial and NSCLC patients. The favorable safety profile and convenience of once-daily dosing could position IDE397 well for long-term use and combinations.

The company's pipeline diversity, including PARG inhibitor IDE161 and partnered programs with GSK, provides multiple shots on goal. However, competition in precision oncology is fierce and IDEAYA will need to maintain its rapid development pace to stay ahead.

IDEAYA's business strategy demonstrates a balanced approach between internal development and strategic partnerships. The collaboration with GSK for the Pol Theta and Werner Helicase programs provides significant milestone potential ($465 million each) and shared development costs, reducing financial risk.

The recent deal with Biocytogen for the B7H3/PTK7 BsADC program shows IDEAYA's commitment to expanding its pipeline with cutting-edge technologies. This $406.5 million potential deal could yield a first-in-class asset with broad applicability.

IDEAYA's focus on multiple first-in-class candidates across various targets (PKC, MAT2A, PARG) positions it well in the competitive oncology landscape. The company's ability to advance five clinical-stage programs while maintaining a strong cash position is commendable. However, the lack of current revenue streams puts pressure on clinical success and future partnering activities to drive value.

SOUTH SAN FRANCISCO, Calif., Aug. 6, 2024 /PRNewswire/ -- IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, provided a business update, and announced financial results for the second quarter ended June 30, 2024.

"We made significant progress advancing four potential first-in-class precision medicine oncology clinical programs this past quarter, and we are on-track to deliver our fifth potential first-in-class program to the clinic this year in Werner Helicase. Importantly, we presented preliminary clinical proof of concept data for IDE397 monotherapy in MTAP-deletion urothelial and lung cancer, demonstrating the ability to deliver confirmed RECIST responses with a favorable AE profile. The IDE397 combination therapy trials in MTAP-deletion solid tumors with our collaborators continue to progress, with the first patient dosed in the Phase 1 trial evaluating IDE397 with Gilead's Trodelvy, and continued dose escalation in the AMG 193 clinical combination with Amgen. We look forward to hosting an investor R&D Day that will profile our rapidly advancing potential first-in-class precision medicine oncology pipeline, where we are targeting multiple additional development candidates by the end of this year," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.

"We were excited to share the compelling interim clinical data from the investigator- and company-sponsored Phase 2 trials of darovasertib in neoadjuvant UM, and look forward to discussing the registrational path forward with the FDA and providing our company-sponsored Phase 2 trial update in over 30 patients during the second half of this year. In addition, the most recent positive interim results observed with IDE397 monotherapy, in addition to the ongoing combination trials, bring us closer to potentially addressing a high unmet need in MTAP-deletion NSCLC, urothelial cancer and other solid tumors, and we are targeting developing a registrational plan in 2025. Separately, we anticipate initiating both the Phase 2 IDE161 monotherapy expansion cohort and the IDE161 in combination with KEYTRUDA cohort in the second half of 2024," said Darrin Beaupre, M.D., Ph.D., Chief Medical Officer, IDEAYA Biosciences.

Clinical Programs and Upcoming Milestones

Darovasertib (IDE196) Program in Tumors with GNAQ or GNA11 Mutations

Darovasertib is a potent and selective protein kinase C (PKC) inhibitor being developed to broadly address primary and metastatic UM. Darovasertib is currently being evaluated in four ongoing clinical trials. The darovasertib and crizotinib combination in MUM has FDA Fast Track designation:

IDE196-002 (NCT05987332) is a Phase 2/3 potentially registration-enabling clinical trial of darovasertib + crizotinib in first-line human leukocyte antigens HLA-A2*02:01(-) MUM. Triple digit patient enrollment has been achieved as of July 31, 2024.
IDE196-001 (NCT03947385) is a Phase 1/2 clinical trial evaluating darovasertib + crizotinib in GNAQ/11 melanomas, including in MUM and metastatic cutaneous melanoma.
Phase 2 trials of darovasertib as neoadjuvant / adjuvant therapy in primary UM:
- IDE196-009 (NCT05907954) is a company-sponsored Phase 2 trial evaluating darovasertib as neoadjuvant treatment of UM prior to primary interventional treatment of enucleation or radiation therapy, and as adjuvant therapy following the primary treatment.
  - Interim efficacy and safety results were reported in conjunction with the Phase 2 investigator-initiated trial (IST) interim data ASCO 2024 presentation.
  - Data from eight patients (six enucleation and two plaque eligible) who have been on darovasertib treatment for 4 months or more as of the database lock of May 24, 2024 demonstrated a median tumor shrinkage (maximum height/base/volume change) of approximately 40%/25%/72% and the majority of the six enucleation patients had reported Eye Saved (i.e., converted to plaque brachytherapy or external beam radiotherapy (EBRT) eligible).
  - Darovasertib had a manageable adverse events (AEs) profile with no drug-related serious adverse events (SAEs) observed; drug-related AEs were predominantly Grade 1 or Grade 2 and approximately 13% of patients reported at least one drug-related Grade 3 AE.
  - The trial has enrolled over 50 patients in 20 sites globally, as of July 31, 2024.
  - An amendment to the study protocol was submitted to the FDA in July 2024 to enable dosing of darovasertib as neoadjuvant and adjuvant therapy up to 12 months each. As part of this amendment the number of patients in the study was increased from 82 to 122 patients and the part 2 of the study will, once the amendment is effective, consist of adjuvant treatment with darovasertib in combination with crizotinib for patients with disease characteristics suggesting high or intermediate risk of metastasis.
  - Additional clinical efficacy update from the company-sponsored Phase 2 of darovasertib neoadjuvant UM trial in over 30 patients is anticipated in the second half of 2024.
- NADOM (NCT05187884) is a Phase 2 neoadjuvant / adjuvant trial of darovasertib in ocular melanoma. This is an IST led by Anthony Joshua, MBBS, PhD, FRACP, Head Department of Medical Oncology, Kinghorn Cancer Centre, St. Vincent's Hospital in Sydney with additional participating sites in Melbourne, Australia.
  - Interim efficacy and safety results were presented at the ASCO 2024 meeting. As of the database lock on May 14, 2024, 13 patients had completed neoadjuvant treatment, 11 patients received adjuvant darovasertib after primary treatment of their UM, with five patients completing the planned six months of therapy. At that time, 75% (nine out of 12 enucleation patients) had confirmed Eye Saved (i.e., converted to plaque brachytherapy or EBRT). After six months, approximately 67% (eight out of 12 enucleation patients) observed greater than 30% tumor shrinkage (maximum volume change) and median tumor shrinkage (maximum volume change) was approximately 47%.
  - Darovasertib monotherapy neoadjuvant treatment had a manageable AE profile with no drug-related SAEs observed. Drug-related AEs were predominantly Grade 1 or Grade 2 and 20% of patients reported at least one drug-related Grade 3 AE.
- IDEAYA has scheduled a Type C meeting with the FDA in the third quarter of 2024 to discuss a potential registrational trial for darovasertib in the neoadjuvant UM setting.

IDE397 Program in Tumors with MTAP Deletion

IDE397 is a potent and selective small molecule inhibitor targeting methionine adenosyltransferase 2 alpha (MAT2A) in patients having solid tumors with methylthioadenosine phosphorylase (MTAP) deletion. IDEAYA continues to focus on evaluating IDE397 in two trials in select monotherapy indications and in high conviction clinical combinations:

IDE397-001 (NCT04794699) is a Phase 1/2 treatment study with monotherapy expansion in MTAP-deletion NSCLC and urothelial cancer. The estimated U.S. MTAP-deletion annual incidence in NSCLC and urothelial cancer is approximately 48,000 patients.
- Selected 30 mg as the move-forward expansion dose for IDE397 monotherapy in MTAP-deletion urothelial cancer and squamous NSCLC based on adverse event profile and preliminary clinical efficacy observed.
- Over 35 global clinical trial sites activated to enable rapid enrollment.
- Reported positive interim data from 18 evaluable MTAP-deletion urothelial and NSCLC patients by RECIST 1.1:
  - ~39% Overall Response Rate (ORR) observed with one complete response and six partial responses. Two partial responses were awaiting confirmation at the time of the update (July 8, 2024), and one urothelial cancer patient that had a 100% tumor reduction in the target lesion at the last CT-scan assessment has now been confirmed. The second adenocarcinoma NSCLC patient is still awaiting confirmation as of July 31, 2024
    - In patients with urothelial cancer: One complete response and two partial responses were observed.
    - In patients with lung cancer: three partial responses were seen in squamous NSCLC patients, and one partial response seen in adenocarcinoma NSCLC patient. There was one non-evaluable patient who discontinued due to rapid clinical progression of cancer fatigue and drug-unrelated adverse events in cycle 1 of treatment.
  - ~94% Disease Control Rate (DCR) seen with one complete response, six partial responses, and 10 stable disease.
  - ~78% of patients (14/18) experienced tumor shrinkage.
  - Preliminary durability assessment showed 11 of the 18 patients are still on treatment, and five of seven RECIST 1.1 responses remain in response. Median duration of treatment, median duration of response, and median progression free survival not yet reached.
  - ~81% circulating tumor DNA (ctDNA) Molecular Response (MR) Rate observed in evaluable subjects with 13 of 16 patients with 50% or greater ctDNA reduction. There were several quality control failures of patient samples that led to unavailability for MR analysis.
  - Overall favorable AE profile. Approximately 5.6% grade 3 or higher drug-related AEs and no drug-related SAEs reported at IDE397 30 mg once-a-day expansion dose. No drug-related AEs leading to discontinuations observed. We anticipate that the favorable AE profile and dosing convenience of a 30 mg once-a-day tablet has the potential to enable long-term dosing and combination development.
  - 30 mg once daily expansion dose achieves target drug coverage and plasma S-adenosyl-l-methionine (SAM) pharmacodynamic reduction associated with preclinical tumor regressions.
- Targeting development of IDE397 registrational plan in MTAP-deletion solid tumors in 2025.
Phase 1/2 trial of IDE397 and AMG 193 in MTAP-Deletion NSCLC (Amgen-sponsored study, NCT05975073)
- Targeting development of joint publication strategy on IDE397 and AMG193 combination in 2024.
- At this time, the IDE397 / AMG 193 clinical combination dose escalation is ongoing. In the past quarter, IDEAYA, in consultation with Amgen, has now financially budgeted to support its obligations for target IDE397 / AMG 193 clinical combination expansion in NSCLC.
First patient dosed in the Phase 1 trial of IDE397 and Trodelvy in MTAP-deletion urothelial cancer (IDEAYA-sponsored, NCT04794699) evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy. The MAT2A-Trop2 antibody-drug conjugate (ADC) combination targets two distinct, yet complementary nodes in the 26% of patients with MTAP-deleted urothelial cancer and has first-in-class potential to improve clinical outcomes for urothelial cancer patients.

IDE161 Program in Tumors with Homologous Recombination Deficiency

IDE161 is a potential first-in-class inhibitor of poly(ADP-ribose) glycohydrolase (PARG), a novel, mechanistically distinct target in the same clinically validated biological pathway as poly(ADP-ribose) polymerase (PARP). IDE161 received two FDA Fast Track designations in platinum-resistant advanced or metastatic ovarian cancer patients having tumors with BRCA1/2 mutations, and in pretreated advanced or metastatic HR+, Her2-, BRACA1/2 mutant breast cancer. IDE161 is currently being evaluated as a monotherapy in IDE161-001 (NCT05787587), a Phase 1 trial of IDE161 in solid tumors with homologous recombination deficiency (HRD). Selection of an initial Phase 1/2 monotherapy expansion dose in HRD solid tumors remains on track for the second half of 2024. IDEAYA is currently validating IDE161 combination opportunities preclinically and targeting identification of additional combination(s) in 2024.

Additionally, IDEAYA is planning to evaluate IDE161 in combination with KEYTRUDA® in patients with microsatellite instability (MSI)-high and microsatellite stable (MSS) endometrial cancer. Clinical first-patient-in for the IDE161 and KEYTRUDA® combination is targeted in the second half of 2024.

KEYTRUDA® is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

GSK-Partnered Programs

GSK101 (IDE705) Program in Tumors with HRD
GSK101 (IDE705) is a potential first-in-class small molecule inhibitor of Pol Theta Helicase being developed as a combination treatment with niraparib for advanced solid tumors with HRD. The dose escalation portion of the GSK-sponsored Phase 1/2 clinical trial to evaluate GSK101 in combination with niraparib, the GSK small molecule inhibitor of PARP, for patients having solid tumors with BRCA or other HR mutations, or with HRD is currently ongoing.

Upon initiation of the Phase 1 dose expansion, IDEAYA will be eligible to receive a $10.0 million milestone payment, with the collaboration having a potential further aggregate later-stage development and regulatory milestones of up to $465.0 million. GSK is responsible for all research and development costs for the program. Upon commercialization, IDEAYA will be eligible to receive up to $475 million of commercial milestones, and tiered royalties on global net sales of GSK101 – ranging from high single-digit to sub-teen double-digit percentages, subject to certain customary reductions.

Werner Helicase Inhibitor in Tumors with High MSI
IDEAYA and GSK remain on track for an IND filing in the second half of 2024 for the selected Werner Helicase inhibitor announced in December 2023. The IND-enabling Good Laboratory Practice (GLP) toxicology studies have been completed for the Werner Helicase inhibitor development candidate. IDEAYA has the potential to earn up to an additional $17.0 million in aggregate milestones through early Phase 1, including $7.0 million upon IND clearance, and is entitled to receive up to $465.0 million in further later-stage development and regulatory milestones. GSK is responsible for 80% of global research and development costs and IDEAYA is responsible for 20% of such costs. Upon commercialization, IDEAYA will be eligible to receive up to $475 million of commercial milestones, 50% of U.S. net profits and tiered royalties on global non-U.S. net sales of the Werner Helicase inhibitor development candidate (DC) – ranging from high single-digit to sub-teen double-digit percentages, subject to certain customary reductions.

B7H3/PTK7 Topo-Payload BsADC Program

IDEAYA entered into an option and license agreement for a potential first-in-class B7H3/PTK7 Topo-Payload BsADC program with Biocytogen in July 2024. The agreement grants IDEAYA an option for an exclusive worldwide license from Biocytogen for a potential first-in-class B7H3/PTK7 Topo-Payload BsADC program. B7H3/PTK7 has been found to be co-expressed in multiple solid tumor types, including double-digit percent prevalence in lung, colorectal, and head and neck cancers, among others. Based on preclinical data, the potential first-in-class B7H3/PTK7 Topo-Payload BsADC program has the potential to be developed as a monotherapy agent and used in combination with multiple programs in IDEAYA's pipeline targeting DDR-based therapies, including PARG inhibitor IDE161. A development candidate nomination for the B7H3/PTK7 Topo-Payload BsADC program is targeted for the second half of 2024.

Under the terms of the agreement, Biocytogen will receive an upfront fee and, upon an option exercise by IDEAYA, be entitled to receive an option exercise fee, development and regulatory milestones and commercial milestone payments, as well as single-digit royalties on net sales. Total potential upfront, option exercise and milestone payments equal an aggregate of $406.5 million, including development and regulatory milestones of $100.0 million.

Next-Generation Precision Medicine Pipeline Programs

Early preclinical research programs focused on pharmacological inhibition of several new targets for patients with solid tumors characterized by defined biomarkers based on genetic mutations and/or molecular signatures are ongoing. These programs have the potential for discovery and development of first-in-class or best-in-class therapeutics with multiple wholly owned DC nominations targeted in the second half of 2024, including in MTAP-deletion solid tumors indications to enable a potential wholly-owned clinical combination with IDE397 and the lysine acetyltransferase 6 (KAT6) pathway.

Financial Results

As of June 30, 2024, IDEAYA had cash, cash equivalents and marketable securities totaling $952.7 million. This compared to cash, cash equivalents and marketable securities of $941.4 million as of March 31, 2024. The increase was primarily attributable to net proceeds of $36.5 million from the sale of common stock shares through IDEAYA's at-the-market offering program during the period from April 1, 2024 to June 30, 2024, partially offset by net cash used in operations.

Subsequent to the reporting period for the quarter ended June 30, 2024, IDEAYA announced the closing in July 2024 of an underwritten public offering of common stock and pre-funded warrants to purchase common stock, generating net proceeds of approximately $283.8 million, after deducting the underwriting discounts and commissions and estimated offering expenses payable by IDEAYA.

There was no collaboration revenue recognized for the three months ended June 30, 2024 similar to the three months ended March 31, 2024. We completed all performance obligations related to the upfront payment under the GSK collaboration agreement as of December 31, 2023. Future collaboration revenue recognized under the GSK collaboration agreement will be related to future milestone payments as they are earned.

Research and development (R&D) expenses for the three months ended June 30, 2024 totaled $54.5 million compared to $42.8 million for the three months ended March 31, 2024. The increase was primarily due to higher stock-based compensation expenses, clinical trial expenses, professional and outside services and consulting expenses.

General and administrative (G&A) expenses for the three months ended June 30, 2024 totaled $10.4 million compared to $8.2 million for the three months ended March 31, 2024. The increase was primarily due to higher stock-based compensation expenses, audit fees and consulting expenses.

The net loss for the three months ended June 30, 2024 was $52.8 million compared to the net loss of $39.6 million for the three months ended March 31, 2024. Total stock compensation expense for the three months ended June 30, 2024 was $9.7 million compared to $6.3 million for the three months ended March 31, 2024.
