Tolmar Announces Expanded Indication for Rubraca® (rucaparib) First and Only PARP Inhibitor to Outperform Docetaxel in a Head-to-Head Phase 3 Trial

On December 19, 2025 Tolmar, Inc. (Tolmar) reported that the U.S. Food and Drug Administration (FDA) has approved an expanded indication for Rubraca (rucaparib), enabling its use prior to chemotherapy for eligible patients with metastatic castration-resistant prostate cancer (mCRPC). The approval is supported by the pivotal TRITON3 Phase 3 trial, which demonstrated that Rubraca is the first and only PARP inhibitor to exceed the efficacy of docetaxel in a direct, head-to-head comparison, marking a significant evolution in treatment sequencing for patients with DNA damage repair (DDR)-deficient tumors.

"This approval reflects a breakthrough moment for patients and for precision oncology," said Anil D’Souza, Chief Executive Officer of Tolmar. "For years, oncologists have relied on docetaxel as an important therapy in this setting. Now, TRITON3 has shown that Rubraca can not only move ahead of chemotherapy but outperform it—supported by clear genomic rationale and superior progression-free survival. Bringing Rubraca earlier in the treatment journey offers physicians a more targeted approach for patients with BRCA mutated prostate cancer."

The TRITON3 study is a Phase 3, multicenter, open-label, randomized trial of rucaparib in chemotherapy-naïve mCRPC patients who had been previously treated with an androgen receptor directed therapy. The study enrolled 405 patients with a mutation in BRCA or ATM who were randomized to rucaparib or the control group, which consisted of physician’s choice of docetaxel, abiraterone acetate, or enzalutamide. Approximately 55% of the patients in the control arm received docetaxel. The primary endpoint was radiographic progression-free survival (rPFS) by independent radiology review (IRR), in patients with mutations in BRCA1, BRCA2 or ATM. TRITON3 was designed as a Phase 3 trial to confirm and expand the efficacy data from TRITON2 in an earlier treatment setting in mCRPC against a relevant control arm. Patients were selected for therapy based on an FDA-approved companion diagnostic for rucaparib.

Key findings include:

Superiority in Radiographic Progression-Free Survival (rPFS):
Rubraca achieved a statistically significant improvement in rPFS vs. the control arm, delivering a median rPFS of 11.2 months vs. 6.4 months , HR 0.50
In a sub-analysis of Rubraca vs Docetaxel, the rPFS was 11.2 months vs. 8.3 months with docetaxel in the BRCA subgroup
Compelling Genomically Driven Benefit:
Patients with BRCA mutations demonstrated the strongest response, showing a ~50% reduction in risk of progression or death vs. docetaxel
Rubraca Tolerability Profile:
The safety profile of Rubraca observed in TRITON3 was consistent with previous studies. In TRITON3, the discontinuation rate for TEAEs was 14.8% for Rubraca-treated patients and 21.5% for the control arm
Prostate cancer is the most diagnosed cancer in U.S. men, with an estimated 313,780 new cases diagnosed in 2025.2 Approximately 10 to 20 percent of patients progress to castration-resistant prostate cancer, an incurable disease, within five years of diagnosis.3 The vast majority have metastases at diagnosis or develop metastases within two years.3 Of these, an estimated 13% have BRCA-mutated mCRPC,4 a disease characteristic associated with a poor prognosis.5 Men with mCRPC and the presence of a germline BRCA2 mutation, a prognostic marker, have more aggressive disease and poorer survival.6 While less common in prostate cancer, germline mutations in BRCA1 are also associated with more aggressive disease6. mCRPC generally responds to initial androgen deprivation therapy.7 However, most patients will inevitably develop treatment resistance.7

Rubraca (rucaparib) U.S. Prostate Cancer FDA-Approved Indication

INDICATION

RUBRACA (rucaparib) is indicated for the treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-associated metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen receptor-directed therapy. Select patients for therapy based on an FDA-approved companion diagnostic for RUBRACA.

SELECT IMPORTANT SAFETY INFORMATION

Myelodysplastic Syndrome (MDS)/Acute Myeloid Leukemia (AML) occur in patients treated with RUBRACA, and are potentially fatal adverse reactions. In 2141 treated patients with ovarian and prostate cancer, MDS/AML occurred in 34 patients (1.6%), including those in long term follow-up. Of these, 14 occurred during treatment or during the 28-day safety follow-up (0.7%).
The duration of RUBRACA treatment prior to the diagnosis of MDS/AML ranged from < 2 months to approximately 72 months. The cases were typical of secondary MDS/cancer therapy-related AML; in all cases, patients had received previous platinum-containing chemotherapy regimens and/or other DNA damaging agents.

In ARIEL3, of patients with ovarian cancer associated with a germline and/or somatic BRCA mutation who were treated with RUBRACA, MDS/AML occurred in 9 out of 129 (7%) patients treated with RUBRACA and 4 out of 66 (6%) patients treated with placebo. The duration of therapy with RUBRACA in patients who developed secondary MDS/cancer therapy-related AML varied from 1.2 to 4.7 years.

In TRITON3, MDS/AML occurred in 2 out of 201 patients (1%) with a BRCA mutation treated with RUBRACA. The duration of therapy with RUBRACA in patients who developed secondary MDS/cancer therapy-related AML varied from 1.4 to 2.3 years.

Do not start RUBRACA until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1). Monitor complete blood counts for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities (> 4 weeks), interrupt RUBRACA or reduce dose and monitor blood counts weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks or if MDS/AML is suspected, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue RUBRACA.

Based on findings from genetic toxicity and animal reproduction studies, RUBRACA can cause fetal harm. Advise male patients with female partners of reproductive potential or who are pregnant to use effective methods of contraception during treatment and for 3 months following last dose of RUBRACA. Advise male patients not to donate sperm during therapy and for 3 months following the last dose of RUBRACA.

Most common adverse reactions of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON3 (≥10%, Grade 1-4) were fatigue/asthenia (61%), musculoskeletal pain (53%), nausea (51%), decreased appetite (34%), diarrhea (31%), constipation (31%), vomiting (25%), dyspnea (19%), dysgeusia (18%), edema (18%), abdominal pain (17%), dizziness (16%), weight decreased (16%), rash (13%), headache (12%), peripheral neuropathy (12%), photosensitivity reaction (12%), and urinary tract infection (10%).

Most common select laboratory abnormalities of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON3 (≥ 25%, Grade 1-4) were increased ALT (68%), decreased neutrophils (67%), decreased phosphate (64%), decreased hemoglobin (60%), increased AST (59%), increased creatinine (56%), increased glucose (45%), decreased lymphocytes (43%), decreased sodium (35%), decreased platelets (34%), and increased calcium (29%).

Most common adverse reactions of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON2 (≥ 20%; Grade 1-4) were fatigue/asthenia (62%), nausea (52%), decreased appetite (28%), rash (27%), constipation (27%), vomiting (22%), and diarrhea (20%).
Most common laboratory abnormalities of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON2 (≥ 35%; Grade 1-4) were increased ALT (69%), decreased leukocytes (69%), decreased phosphate (68%), decreased absolute neutrophil count (62%), decreased hemoglobin (59%), increased alkaline phosphatase (44%), increased creatinine (43%), decreased lymphocytes (42%), increased triglycerides (42%), decreased platelets (40%), and decreased sodium (38%).

Concomitant administration of RUBRACA with CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates can increase the systemic exposure of these substrates, which may increase the frequency or severity of adverse reactions of these substrates. If concomitant administration is unavoidable between RUBRACA and substrates of these enzymes where minimal concentration changes may lead to serious adverse reactions, decrease the substrate dosage in accordance with the approved prescribing information.

If concomitant administration with warfarin (a CYP2C9 substrate) cannot be avoided, consider increasing the frequency of international normalized ratio (INR) monitoring.

The SureSelect and Avida capabilities both fill a critical gap in native-read sequencing by enabling precise, custom targeting up to 1 Mb, while preserving native DNA features such as methylation and structural variants. By eliminating off-target sequencing, DNA damage of traditional bisulfite-based methods, and biases introduced by PCR amplification, researchers can capture true biology across large and short, customized genomic regions. This opens new doors for liquid biopsy and targeted genomic applications with cost-efficient, scalable, and highly precise approaches suitable for a broad-array of research and screening applications.

"Multi-omic biology is essential for understanding disease, but for broad adoption it has to be delivered in a way that scales," said Dean Lilley, Senior Director of Product Development at Wasatch BioLabs. "Our alignment with Agilent ensures that native-read targeted sequencing delivers integrated genetic and epigenetic insight, while establishing the consistency, reproducibility, and operational reliability required for high-throughput research and potential future clinical translation.

Early adopters in oncology, neurology, rare disease, and prenatal research are already applying dTMS to resolve structural variation, allelic context, repeat expansions, and methylation patterns in a unified assay. These programs demonstrate how native-read targeted sequencing can support more comprehensive, mechanism-informed profiling across research areas such as liquid biopsy and large cohort studies.

"Partnering with Wasatch BioLabs allows Agilent to deliver a next-generation experience for customers who need both innovation and operational flexibility," said Nina Green, vice president and general manager of Agilent’s Clinical Diagnostics Division. "By integrating SureSelect and Avida enrichment with Wasatch’s novel sequencing technology and robust send-out service model, we are enabling customers to access high-quality NGS data without workflow barriers. This collaboration accelerates adoption, improves turnaround times, and provides a powerful, innovation-led path to achieving high-confidence genomic insights at any scale."

Under the agreement, WBL and Agilent will jointly deliver scientific content, educational programming, and technology demonstrations through 2027. The organizations anticipate the collaboration will scale adoption of native-read targeted sequencing and accelerate the development of cost-efficient, relevant native-read assays.

WBL welcomes additional partners interested in integrating the targeted sequencing assay into their research or development programs. The service will remain in early access through Q1 2026. Early adopters will have the opportunity to shape future enhancements and gain first access to new capabilities.

Data thus far from the dose escalation portion of the trial demonstrated that NDI-219216 has a favorable safety profile, with no dose-limiting toxicities or severe treatment-related adverse events observed through the maximum administered dose (MAD). No maximum tolerated dose (MTD) was reached. Pharmacokinetic and pharmacodynamic data indicated that NDI-219216 achieved robust WRN target engagement for more than 24 hours at multiple dose levels. The company completed dose escalation approximately nine months ahead of schedule, with enrollment continuing to accelerate across global clinical sites.

"Completing dose escalation represents an important milestone in the clinical development of NDI-219216," said Anita Scheuber, M.D., Ph.D., Senior Vice President, Therapeutic Area Head, Oncology at Nimbus. "We are encouraged by the favorable safety profile and robust target coverage that is translating into early clinical activity in patients. The accelerated timeline, driven by strong patient recruitment, underscores the significant unmet need in this patient population. These results reinforce our confidence in NDI-219216’s differentiated profile and its potential to address patients with MSI-H tumors who have limited treatment options. We look forward to sharing clinical data at an upcoming scientific conference."

The Phase 1/2 clinical trial (NCT06898450) is an open-label study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of NDI-219216 in patients with advanced solid tumors. The study is being conducted in three parts: Part A (dose escalation), Part B (dose optimization), and Part C (dose expansion). With Part A now complete, the trial is advancing to Part B, which will determine the recommended dose(s) for further evaluation.

About NDI-219216

NDI-219216 is a highly potent and selective non-covalent investigational inhibitor of Werner syndrome helicase (WRN) activity being developed for the treatment of MSI-H tumors. WRN is a DNA helicase required for DNA replication and DNA repair and is a validated synthetic lethal target for tumors with microsatellite instability (MSI). MSI is a phenotypic consequence of deficient mismatch repair (dMMR) and occurs in various tumor types, including colorectal, gastric, and endometrial cancers. In preclinical studies, treatment with NDI-219216 exhibited robust antitumor activity across multiple cell line-derived xenograft (CDX) and patient-derived xenograft (PDX) MSI-H tumor models, including models for colorectal, gastric, and endometrial cancers.
