Price transparency & out-of-pocket payments for medications: Implications of associated delivery fees in the United States

Article

Author: Kaye, Deborah R ; Scales, Charles D ; George, Daniel J ; Lee, Hui-Jie ; Bundorf, M Kate

Background:

Price transparency has been cited as a tool to reduce out-of-pocket (OOP) payments to patients. These tools for prescription drugs often focus on the price to patients for the drug alone. However, costs associated with drug delivery (i.e. infusion center fees, labs, etc) are often unknown and could impact the effectiveness of price transparency tools. Objective: To examine total OOP payments on day of drug receipt ("full day", i.e. drug + drug administration fees) out-of-pocket (OOP) payments associated with six first-line treatments for metastatic castrate resistant prostate cancer and compare these with payments for drug alone and by insurance type.

Methods:

Using the IBM Marketscan databases, we identify male patients who initiated treatment with one of six focus drugs (docetaxel, abiraterone, enzalutamide, sipuleucel-T, cabazitaxel, and radium-223) used to treat mCRPC from 07/01/2013-06/30/2019. We calculated total OOP payments on day of drug receipt (full day OOP payments) by drug type for six first line treatments. We then used a two-part model to assess the association of first-line therapy with OOP payments for the four most frequently prescribed during the study time period.

Results:

We find that there is variation in the proportion of payments for drug alone relative to full day payments across first-line treatments. However, regression-adjusted mean full day OOP payments are not statistically different across first-line treatments for mCRPC for the four most frequently prescribed drugs. There are differences in the likelihood that an individual will incur any OOP payment by first-line treatment type and by health plan type.

Conclusion:

These analyses suggest that when accounting for additional services required on the day of drug receipt, the amount a patient pays to receive a medication for mCRPC can be very different from the OOP payment for the drug alone; these payments also vary by drug and health plan type. Therefore, price transparency for drug alone may not lead to reduced OOP payments for patients.

Boolean network-based identification of optimal drug combinations for prostate cancer

Article

Author: Datta, Aniruddha ; Kumar, Addanki Pratap ; Bhattacharjee, Pranabesh

Prostate cancer is one of the most common cancers among men in the United States and is a leading cause of cancer-related deaths and the second most common cancer in men worldwide. In this study, we used a Boolean network model to analyze prostate cancer signaling pathways and to identify optimal drug combinations for precision therapy. By integrating publicly available biological signaling pathway data with recent research findings, we developed a comprehensive model that represents protein-protein interactions, gene mutations, and pathway dysregulation. Faults induced by mutations were modeled using the "stuck at 0" or "stuck at 1" fault paradigms, capturing the impact of genetic alterations on pathway behavior. The model was simulated across various drug combinations to determine which therapies could most effectively alleviate the aberrant signaling caused by specific mutations. To quantify therapeutic efficacy, we calculated a Size Difference (SD) score, a metric analogous to Hamming distance, measuring the deviation from normal, for each drug combination and fault scenario. The results revealed that drug combinations involving Berberine, Docetaxel, Olaparib, and Enzalutamide showed promising prediction efficacy (more than 90 %), indicating higher therapeutic potential. A distinguishing feature of this work is that, in addition to the standard prostate cancer drugs, we have included Berberine, a non-toxic natural compound with beneficial effects. These computational findings provide a framework for future experimental and clinical validation, which is necessary to confirm the therapeutic relevance of the predicted drug combinations.

The YAP1 and EPHA3 receptor tyrosine kinase axis regulates cellular plasticity and treatment response

Article

Author: Dwead, Abdulrahman M ; Cinar, Bekir ; Khazaw, Kezhan ; Al-Mathkour, Marwah M

The transcriptional coregulator YAP1 and the receptor tyrosine kinase EPHA3 regulate key cellular processes, including cell interactions, motility, survival, tissue development, carcinogenesis, and metastasis. Although their individual roles have been extensively studied, their cooperative functions remain poorly understood. Here, we investigated the relationship between EPHA3 and YAP1 in human prostate tumor tissues and cell models. Integrated transcriptomic and immunological analyses reveal a strong positive correlation between YAP1 and EPHA3 expression, which is significantly associated with tumor progression. EPHA3 knockout reduces cell proliferation and increases sensitivity to the androgen receptor inhibitor enzalutamide and the YAP1-TEAD inhibitor CA3 in vitro. EPHA3 depletion also reduces GTP-bound active RHOA and phosphorylated ERK levels and differentially affects epithelial-mesenchymal transition and cancer stem cell programs. In addition, EPHA3 silencing attenuates cell migration and invasion, an effect dependent on YAP1 activation. Bioinformatics analysis further indicates that high YAP1 and EPHA3 correlate with developmental and EMT-related gene signatures. These results demonstrate that the YAP1-EPHA3 axis is a key mediator of cell survival, plasticity, and tumor progression, and may serve as a promising cancer drug target.

Oric’s PRC2 inhibitor rinzimetostat combo regimen advances to Phase III trial in mCRPC

ORIC Pharmaceuticals (Nasdaq: ORIC) reported Phase Ib dose optimization data for rinzimetostat in combination with darolutamide in post-abiraterone metastatic castration-resistant prostate cancer (mCRPC), selecting 400 mg once daily as the recommended Phase 3 dose and announcing plans to initiate the Himalayas-1 global Phase III registrational trial in the first half of 2026. At a median follow-up of approximately five months, a five-month landmark rPFS rate of 84% appears numerically favorable relative to historical benchmarks for approved therapies in this setting, though the dataset remains small and cross-trial comparisons are limited. Trial specifics The Phase Ib dose optimization trial enrolled patients with mCRPC who had received prior androgen receptor pathway inhibitor (ARPI) therapy and up to one prior line of chemotherapy. The post-abiraterone cohort included 18 patients treated at 400 mg once daily and 15 at 600 mg once daily, both in combination with darolutamide (Nubeqa) at 600 mg twice daily. In 18 efficacy-evaluable patients at the 400 mg dose, landmark rPFS rates were 93%, 84%, and 84% at 3, 4, and 5 months respectively, with a median follow-up of 4.9 months. Among 15 patients with at least one post-baseline PSA assessment, 47% achieved a PSA50 response, with 33% confirmed. In 14 patients with detectable ctDNA at baseline, 71% achieved greater than 50% ctDNA reduction. For context, ORIC cited 5-month landmark rPFS rates of approximately 60% to 75% for approved therapies including enzalutamide (Xtandi), cabazitaxel (Jevtana), docetaxel (Taxotere), and lutetium-177 vipivotide tetraxetan (Pluvicto) in comparable populations, though these figures derive from separate trials with different patient characteristics. Treatment-related adverse events at the 400 mg dose were predominantly Grade 1. The most common were fatigue (39%), diarrhea (22%), and nausea (22%). A single Grade 3 TRAE was observed; no Grade 4 or 5 events were attributed to either drug. Dose modifications were rare, with one interruption and one discontinuation and no dose reductions required across the cohort. The dose selection followed an exposure-response analysis conducted across more than 100 patients in both single-agent and combination settings, in alignment with the FDA’s Project Optimus initiative. That analysis found comparable efficacy at 400 mg and 600 mg, but identified statistically significant associations between higher drug exposure and increased toxicity and treatment modifications, favoring the lower dose on safety grounds. Rinzimetostat and PRC2 inhibition Rinzimetostat is an allosteric inhibitor of polycomb repressive complex 2 (PRC2) acting through the EED subunit. PRC2 mediates histone H3 lysine 27 trimethylation (H3K27me3), an epigenetic modification associated with transcriptional silencing of differentiation programs. In prostate cancer, PRC2 activity has been implicated in the transition toward AR-indifferent or neuroendocrine phenotypes following ARPI exposure — a resistance mechanism not addressed by sequential AR-directed therapy. Pairing rinzimetostat with darolutamide, an AR antagonist with a distinct binding conformation and low CNS penetration, is designed to simultaneously block AR signaling and suppress epigenetic resistance pathways. The most direct competitive reference point is mevrometostat (PF-06821497), Pfizer’s EZH2-targeting PRC2 inhibitor, which is currently in Phase III in mCRPC in combination with enzalutamide. ORIC has positioned rinzimetostat’s safety profile as a potential differentiator, citing lower rates of Grade 3 or higher events and fewer dose modifications relative to competitor regimens, though cross-trial comparisons are limited by differences in patient populations, prior therapy, and data maturity. An earlier EZH2 inhibitor combination effort in prostate cancer, the CELLO-1 trial evaluating tazemetostat with an ARPI, was terminated, leaving the field without a validated precedent for this mechanism in registrational testing. The post-abiraterone mCRPC population represents a setting with limited oral, biomarker-agnostic options. Approved PARP inhibitors — olaparib, rucaparib, and the combination regimens talazoparib plus enzalutamide and niraparib plus abiraterone — are restricted to patients with homologous recombination repair mutations, estimated at roughly 25%-30% of mCRPC cases. Pluvicto gained a label expansion in early 2025 covering pre-taxane, post-ARSI mCRPC, but requires PSMA-PET imaging, specialized nuclear medicine infrastructure, and intravenous administration. Chemotherapy with docetaxel or cabazitaxel carries a toxicity burden that limits use in patients with compromised performance status. The unselected post-abiraterone population — approximately 17,000 new patients annually in the US by ORIC’s estimate — lacks a well-tolerated oral targeted option with a novel mechanism. The planned Himalayas-1 trial will enroll approximately 600 patients across more than 250 sites in over 20 countries, randomized 1:1 to rinzimetostat 400 mg once daily plus darolutamide versus physician’s choice of an AR inhibitor or chemotherapy. The primary endpoint is rPFS; overall survival is the key secondary endpoint. ORIC also reported early data from 19 patients with mCRPC previously treated with AR inhibitors other than abiraterone, showing 5-month landmark rPFS of 85%, suggesting potential applicability beyond the post-abiraterone cohort, though sample sizes remain too small to draw firm conclusions.

Oric to advance prostate cancer drug to Phase 3, but combo choice raises doubts

Oric Pharmaceuticals on Tuesday detailed its plans to advance a PRC2 inhibitor into a registrational program for prostate cancer after sharing results from a Phase 1b trial. But the company’s shares $ORIC dropped by as much as 25% before market open Wednesday as investors had reservations about the biotech’s choice of androgen receptor inhibitor it will combine the investigational drug with. Oric said it plans to advance its candidate, known as rinzimetostat, and Bayer’s Nubeqa into a Phase 3 study. The trial will enroll 600 patients with metastatic castration-resistant prostate cancer (mCRPC) across more than 20 countries. It is set to start in the first half of this year. Jefferies analysts wrote Wednesday that the negative stock move might be due to onlookers thinking that Johnson & Johnson’s Erleada would have been a “better fit strategically” than Nubeqa. Results from a recent head-to-head real-world analysis show Erleada cut the risk of death by 51% compared with Nubeqa in certain prostate cancer patients, although they aren’t the same ones Oric is targeting. Oric’s early-phase trial recruited mCRPC patients who had a median two prior lines of therapy, including previous treatment with abiraterone. The analysts wrote that Oric decided to opt for Nubeqa because it has a lower risk of drug-drug interactions with the investigational drug compared with Erleada. Oric’s choice of combination approach was also based on data from the Phase 1b trial, which tested two different doses of rinzimetostat with Nubeqa, but also with Erleada. The Tuesday release did not report data with Erleada. Results from the Phase 1b trial also led to Oric choosing the lower dose (400 mg) of rinzimetostat versus a higher one (600 mg). The company said that the higher dose was associated with a “modestly higher rate of adverse events.” The most common side effects at the lower dose were fatigue, diarrhea and nausea. There were no grade 4 or 5 events associated with the regimen. The company added both doses had “comparable efficacy,” although the Tuesday data were not split by dose level. Of the 18 evaluable patients treated with the investigational combo of rinzimetostat and Nubeqa, 84% were still alive with no disease progression at five months with a median follow-up of 4.9 months. With the caveat of cross-trial comparison, the Tuesday data are “consistent with” the results attained by Pfizer’s candidate, called mevrometostat, in combination with Xtandi in a Phase 3 trial, despite Oric patients being more heavily pretreated, the Jefferies analysts said. Both rinzimetostat and mevrometostat inhibit the PRC2 complex, but via different subunits — rinzimetostat targets EED, while mevrometostat acts on EZH2. Editor’s note: This story was updated to clarify drug mechanisms.
