ORIC Pharmaceuticals Announces First Patients Dosed Across Three Expansion Cohorts in Phase 1b Trial of ORIC-114 in Patients with Mutated NSCLC

On April 15, 2024 ORIC Pharmaceuticals, Inc. (Nasdaq: ORIC), a clinical stage oncology company focused on developing treatments that address mechanisms of therapeutic resistance, reported the completion of the dose escalation portion of the Phase 1b trial of ORIC-114 in patients with advanced solid tumors with EGFR and HER2 exon 20 alterations or HER2 amplifications (Press release, ORIC Pharmaceuticals, APR 15, 2024, View Source [SID1234642071]). Based upon these data, ORIC selected the two provisional recommended Phase 2 dose (RP2D) levels of ORIC-114 at 80 mg and 120 mg QD, which are being further evaluated in three dose expansion cohorts for dose optimization and final RP2D selection. These expansion cohorts have now been initiated in patients with non-small cell lung cancer (NSCLC) with EGFR exon 20 (EGFR exon 20 inhibitor naïve), HER2 exon 20, or EGFR atypical mutations. The company also announced the initiation of an extension cohort for the treatment of patients with first-line, treatment-naïve EGFR exon 20 NSCLC.

"Following the positive dose escalation data reported at ESMO (Free ESMO Whitepaper) 2023, we are excited to announce the advancement of ORIC-114 into Phase 1b dose expansion," said Pratik Multani, M.D., chief medical officer of ORIC. "Encouraging findings from the Phase 1b dose escalation phase of the trial demonstrated a potential best-in-class profile for ORIC-114, with notable systemic responses and CNS responses, as well as a favorable safety profile, in heavily pre-treated patients. Based on these results, we have identified the two dose levels that we are now advancing into Phase 1b expansion cohorts to determine the final RP2D for further development, including potential registrational cohorts. At the request of many of our investigators and because of the lack of other CNS-active agents against EGFR exon 20, we are also extending our trial to include a cohort evaluating first-line, treatment-naïve NSCLC. We are hopeful that the expansion portion of the trial will validate and build upon the encouraging efficacy seen in the dose escalation, and plan to report results in the first half of 2025."

The Phase 1b dose escalation part of the trial evaluated ORIC-114 in patients with advanced solid tumors with EGFR and HER2 exon 20 alterations or HER2 amplifications. Patients previously treated with an exon 20 targeted agent were eligible, including patients with CNS metastases that were either treated or untreated but asymptomatic. Nearly all other clinical trials with EGFR exon 20 inhibitors severely restricted the eligible patient population and excluded patients with active or untreated brain metastases and patients previously treated with an EGFR exon 20 inhibitor. The primary objectives were to determine the provisional RP2D, and additional objectives included characterization of the safety, tolerability, pharmacokinetic, and preliminary antitumor activity.

The Phase 1b expansion portion of the trial will evaluate the safety and efficacy of ORIC-114 at the provisional RP2D levels of 80 mg and 120 mg QD in patients with mutated NSCLC, including EGFR exon 20 (EGFR exon 20 inhibitor naïve), HER2 exon 20, and EGFR atypical mutations. The primary objectives are to determine the RP2D, and additional objectives include assessment of efficacy in terms of objective response rate, duration of response and progression-free survival, including intracranial activity, as well as further characterization of the safety profile of ORIC-114.

About ORIC-114
ORIC-114 is a highly selective, brain penetrant, orally bioavailable, irreversible inhibitor designed to selectively target EGFR and HER2 with high potency against exon 20 insertion mutations, making it a promising therapeutic candidate to address the unmet medical need of having both meaningful systemic as well as CNS antitumor activity.

About NEXICART-1

NEXICART-1 (NCT04720313) is an ongoing Phase 1b/2a, open-label study evaluating the safety and efficacy of NXC-201 (formerly HBI0101), in adults with relapsed/refractory multiple myeloma and AL amyloidosis.

The primary objective of the Phase 1b portion of the study is to characterize the safety and confirm the Maximally Tolerated Dose (MTD) and Phase 2 dose of NXC-201. The Phase 2 portion of the study will evaluate the efficacy and safety of NXC-201 with endpoints of overall survival, progression-free survival and response rates according to International Myeloma Working Group (IMWG) Uniform Response Criteria.

The Phase 1b portion of the ongoing Phase 1b/2 clinical trial has been successful in determining the recommended Phase 2 dose (RP2D) of 800 million CAR+T cells. The expected primary endpoint for the Phase 2 portion of the ongoing Phase 1b/2a clinical trial of NXC-201 in relapsed/refractory AL Amyloidosis is overall response rate. ImmixBio plans to submit data to the FDA in AL amyloidosis once 30-40 patients are treated with NXC-201.

About NXC-201

We believe NXC-201 (formerly HBI0101) is the only "Single-Day CRS" CAR-T cell therapy that is uniquely suited to target AL Amyloidosis and other autoimmune diseases. It is being studied in a comprehensive clinical development program for the treatment of patients with relapsed/refractory AL amyloidosis, and expanding into other autoimmune indications. These trials build on a robust NXC-201 clinical dataset initiated in February 2021. NXC-201 has been awarded Orphan Drug Designation (ODD) by the FDA in both AL Amyloidosis and multiple myeloma, and awarded EU ODD by the EMA in AL Amyloidosis.

About AL Amyloidosis

AL amyloidosis is a systemic disorder caused by an abnormality of plasma cells in the bone marrow. Misfolded amyloid proteins produced by plasma cells cause buildup in and around tissues, nerves and organs, gradually affecting their function. This can cause progressive and widespread organ damage, and high mortality rates.

U.S. observed prevalence of relapsed/refractory AL Amyloidosis is growing 12% per year according to Staron, et al Blood Cancer Journal, estimated to reach 33,277 patients in 2024. The Amyloidosis market was $3.6 billion in 2017, expected to reach $6 billion in 2025, according to Grand View Research.

Nature Medicine Publishes Interim Results from Gritstone bio’s Phase 1/2 Study of “Off-the-Shelf” Neoantigen Vaccine Platform (SLATE)

On April 15, 2024 Gritstone bio, Inc. (Nasdaq: GRTS), a clinical-stage biotechnology company working to develop the world’s most potent vaccines, reported that a paper detailing the development of its "off-the-shelf" neoantigen platform, SLATE, recently published in Nature Medicine (Press release, Gritstone Bio, APR 15, 2024, View Source [SID1234642068]). The paper, "A shared neoantigen vaccine combined with immune checkpoint blockade for advanced metastatic solid tumors: phase 1 trial interim results," describes a novel immunodominance hierarchy of tumor neoantigens (including KRAS) that Gritstone discovered in Phase 1 translational studies and leveraged to develop SLATE-KRAS, a "pure" KRAS-directed candidate that demonstrated superior immunogenicity to the initial version in a subsequent Phase 2 study and is currently being evaluated in a novel cell therapy-vaccine combination study run by Steven A. Rosenberg of the National Cancer Institute (NCT06253520).

"The publication of these findings in Nature Medicine highlights the promise of our ‘off-the-shelf’ or shared neoantigen approach in solid tumors, one of the many elements embedded within our mission to develop the world’s most potent vaccines," said Andrew Allen, M.D., Ph.D., Co-founder, President, and Chief Executive Officer of Gritstone bio. "Our team’s innovative work to develop, optimize and validate SLATE positions Gritstone with two promising platforms to execute against our neoantigen-directed approach to oncology. It also enabled the pioneering collaboration that we are currently advancing with Dr. Rosenberg of the NCI, a luminary in the field. SLATE is ready for ‘plug and play’ application across a spectrum of solid tumors and could serve as a great complementary platform to GRANITE, our personalized vaccine program. We continue to have great conviction that both approaches could unlock new levels of immune responses for patients with solid tumors."

"This important publication underscores that a deep understanding of the mechanism and performance of therapeutic neoantigens in humans is likely critical for success in the promising field of neoantigen-directed immunotherapy. It also demonstrates our ability to select tumor antigens and optimize cassette design to elicit a potent antigen-specific immune response," said Karin Jooss, Ph.D., Executive Vice President, and Head of R&D at Gritstone bio. "We believe we have a leading understanding of the hierarchy of antigen presentation and competition – a great example outlined in this paper, where we took SLATE from bench to bedside to bench, and back – and have applied that understanding to optimize the design of our oncology vaccines. The learnings and techniques described add to Gritstone’s already robust body of clinical insights to drive potent tumor-specific T cell responses to neoantigens, a unique potential advantage in the field."

Results from the SLATE 1/2 Study
The data published in Nature Medicine report the interim safety, tolerability and immunogenicity results from the Phase 1 portion of the Phase 1/2 clinical trial (NCT03953235) assessing the off-the-shelf vaccine SLATEv1 in patients with advanced/metastatic solid tumors. SLATEv1 utilizes a heterologous ChAd68 followed by samRNA-based vaccine regimen encoding 20 shared neoantigens targeting multiple recurrent mutations in several oncogenes, including KRAS, TP53, BRAF and CTNNB1. Neoantigens were identified using Gritstone bio’s proprietary neoantigen prediction platform, EDGETM, and selected based on shared mutation and matched HLA frequencies in patient populations with solid tumors. Biased T cell responses toward HLA-matched TP53 neoantigens encoded in the vaccine relative to KRAS neoantigens expressed by the patients’ tumors, indicated a previously unknown hierarchy of neoantigen immunodominance that may impact the therapeutic efficacy of multi-epitope shared neoantigen vaccines. These data led to the development of SLATE-KRAS, a vaccine focused on KRAS-derived neoantigens that subsequently was evaluated in the Phase 2 portion of the clinical study. Initial Phase 2 data suggesting an increased vaccine induced T cell response were presented in September 2022 (press release).

About SLATE ("off-the-shelf" neoantigen vaccine program)
Gritstone’s neoantigen-based vaccine programs, GRANITE (personalized) and SLATE ("off-the-shelf) are engineered to elicit a significant T cell response for patients with solid tumors. Like GRANITE, SLATE uses Gritstone’s proprietary epitope identification platform (EDGE) and vaccine vectors (Chimpanzee Adenovirus and self-amplifying mRNA) to deliver each patient a set of neoantigens that are predicted to drive a T cell response. Unlike GRANITE, SLATE delivers a set of neoantigens that are shared across a subset of cancer patients based on common gene mutations, such as KRAS mutations. In Phase 1/2 study, SLATE-KRAS demonstrated positive results in patients with late-line non-small cell lung cancer and microsatellite stable colorectal cancer. With these results, Gritstone believes the SLATE platform is ready for ‘plug and play’ application across solid tumor indications and shared tumor neoantigen classes.
