TPS4164 Background: Biliary tract cancer (BTC) is an aggressive disease with a poor prognosis. Gemcitabine + cisplatin (GemCis) is the accepted global standard of care (SoC), however key cancer resistance mechanisms associated with the transport, activation and breakdown of gemcitabine are known to limit its clinical activity across a range of tumor types, including BTC. NUC-1031 is a phosphoramidate transformation of gemcitabine designed to overcome these key resistance mechanisms and generate much higher levels of the active anti-cancer metabolite, dFdCTP, in cells. Promising efficacy has been observed with single-agent NUC-1031 in a phase I study in advanced solid tumors and in the phase Ib ABC-08 study of NUC-1031 + cisplatin for first-line treatment of advanced BTC. Of 21 patients enrolled in 2 dose cohorts (NUC-1031 625 mg/m2 or 725 mg/m2 + cisplatin 25 mg/m2 on Days 1 and 8 of 21-day cycle), 16 were considered to be efficacy evaluable. In this population, 1 patient had a CR and 6 patients had PRs, resulting in an ORR of 44% (7/16). This compares favorably to the 26% ORR reported for the SoC regimen. In addition, 6 patients had SD, resulting in a DCR of 81% (13/16). The combination was well tolerated with no unexpected AEs or DLTs. The recommended dose of NUC-1031 with cisplatin was 725 mg/m2. The tolerability profile, together with encouraging efficacy led to initiation of a global registrational study. Methods: NuTide:121 is a phase III, open-label, randomized study of NUC-1031 + cisplatin vs GemCis for first-line treatment of advanced BTC. Patients ≥18 years with histologically- or cytologically-confirmed BTC (including cholangiocarcinoma, gallbladder, or ampullary cancer), who have had no prior systemic chemotherapy for locally advanced/metastatic disease, are eligible. A total of 828 patients are being randomized (1:1) to either 725 mg/m2 NUC-1031 or 1000 mg/m2 gemcitabine, both with 25 mg/m2 cisplatin, administered on Days 1 and 8 of 21-day cycles. Primary endpoints are OS and ORR. Secondary endpoints include PFS, safety, PK and patient-reported quality of life. In addition to the final analysis, three interim analyses are planned. The study has passed an initial safety analysis, with no protocol changes required. NuTide:121 is being conducted at approximately 130 sites across North America, Europe and Asia Pacific. Clinical trial information: NCT04163900.

TPS4586 Background: The standard of care for patients with muscle-invasive bladder cancer (MIBC) consists of neoadjuvant chemotherapy and radical cystectomy (RC) or chemoradiotherapy (CRT). However, RC is associated with potential morbidity or mortality from the procedure. TAR-200 is an intravesical drug-delivery system designed for the local continuous release of gemcitabine within the bladder. Cetrelimab is an investigational immunoglobulin G4 anti–programmed cell death protein-1 antibody. In patients with MIBC, this clinical trial will evaluate whether combination treatment with intravesical TAR-200 and systemic cetrelimab will result in enhanced local and systemic antitumor activity versus concurrent CRT. Methods: SunRISe-2 (NCT04658862) is a prospective, multicenter, open-label, randomized phase 3 study evaluating the efficacy and safety of intravesical TAR-200 plus systemic cetrelimab versus CRT in participants with MIBC. Eligible participants are aged ³18 years with an ECOG performance status of 0, 1, or 2, and histologically proven, cT2-T4a, N0, M0 urothelial carcinoma of the bladder diagnosed within 90 days of the randomization date, and who refuse or are ineligible for RC. Approximately 550 participants will be randomized in a 1:1 ratio and with stratification by 2 factors: transurethral resection of bladder tumor screening results (visibly complete vs incomplete) and screening tumor stage (T0 vs Ta/T1/Tis vs T2-T4a). Participants in Arm 1 will receive intravesical TAR-200 every 3 weeks for the first 18 weeks on study; and, beginning at week 24, every 12 weeks through study year 3. Cetrelimab will be dosed every 3 weeks until month 18. Participants in Arm 2 will receive standard of care CRT (with either cisplatin or gemcitabine, for up to 6 weeks). A primary disease assessment will be performed at week 18 to evaluate treatment response in both arms. Subsequent assessments (axial imaging and cystoscopy) will occur at week 24 and every 12 weeks thereafter through study year 2, and then every 24 weeks through study year 5. The primary endpoint is bladder intact event-free survival. Key secondary endpoints include metastasis-free survival, overall survival, overall response rate (at week 18), and safety and tolerability. Other/exploratory end points include assessments of cancer-specific survival, time to symptomatic progression, pharmacokinetics, immunogenicity, health-related quality of life, healthcare resource utilization, and biomarkers. Participants are being enrolled at approximately 272 study sites worldwide. The study opened for enrollment in December 2020. Clinical trial information: NCT04658862.

TPS4592 Background: Despite advances in therapy of clear cell renal cell carcinoma, outcomes for patients with aRCCVH remain poor and these patients have typically been excluded from pivotal phase III studies. COSMIC-313 (NCT03937219) exploring C/N/I vs N/I excludes those with aRCCVH. Given responses seen with C as well as N/I in aRCCVH, there is reason to explore this triplet combination in this population. Methods: NCT04413123 is single arm phase 2 trial multi-institutional study involving Dana-Farber Cancer Institute, Beth Israel Deaconess Medical Center, Winship Cancer Institute, Karmanos Cancer Center, University of California in San Diego and University of Texas Southwestern. The primary objective is to assess the objective response rate (ORR) by investigator-assessed Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 of C in combination with N/I in aRCCVH. Key secondary endpoints are progression-free survival (PFS), overall survival (OS) and toxicity by Common Terminology Criteria for Adverse Events (CTCAE) version 5. Mandatory pretreatment biopsy (unless medically infeasible) is required for correlative analysis to define the composition and transcriptional states of tumor and immune cells within the aRCCVH microenvironment in addition to determining the number and state of tumor-infiltrating T cell clones in aRCCVH and relation to response. Any variant histology is allowed, including clear-cell RCC with over 80% sarcomatoid features. Patients may be treatment naïve or received prior therapy including up to one anti-vascular endothelial growth factor agent not including C; prior therapy with immune checkpoint inhibitors is exclusionary. All International Metastatic RCC Database Consortium risk classifications are allowed; patients should have adequate organ function with performance status 0-1. C will be administered at a starting dose of 40 mg daily. N will be dosed at 3 mg/kg with I 1 mg/kg every 3 weeks followed by maintenance N 480 mg IV every 4 weeks and will be continued until progressive disease or unacceptable toxicity. C can be reduced to. 20 mg daily or 20 mg every other day as needed for toxicity. Dose reductions of N or I are not permitted but delays up to 12 weeks are allowed; N may be continued without I if toxicity can be directly attributed to I. Radiographic imaging is performed at baseline with first scheduled assessment at 12 weeks then every 8 weeks thereafter. A one-stage design is employed to enroll 40 eligible patients, which provides 93% power at 1-sided alpha of 0.09 to distinguish an ORR of 40% versus 20%. 12 or more responses are required to deem treatment promising. Seven of the planned 40 patients have been enrolled as of 2/1/2021. Clinical trial information: NCT04413123.

TPS4596 Background: There is no standard adjuvant systemic therapy that increases overall survival (OS) over surgery alone for non-metastatic RCC. Anti-PD-1 nivolumab (nivo) improves OS in metastatic RCC and is well tolerated. In mouse models, priming the immune system prior to surgery with anti-PD-1 results in superior OS compared to adjuvant dosing. Remarkable pathologic responses have been seen with neoadjuvant PD-1 in multiple ph 2 studies in bladder, lung and breast cancers. Phase 2 neoadjuvant RCC trials of nivo show preliminary feasibility and safety with no surgical delays. PROSPER RCC seeks to improve clinical outcomes by priming the immune system with neoadjuvant nivo prior to nephrectomy followed by continued immune system engagement with adjuvant blockade in patients (pts) with high risk RCC compared to standard of care surgery alone. Methods: This global, unblinded, phase 3 National Clinical Trials Network study is accruing pts with clinical stage ≥T2 or TanyN+ RCC of any histology planned for radical or partial nephrectomy. Select oligometastatic disease is permitted if the pt can be rendered ‘no evidence of disease’ within 12 weeks of nephrectomy (≤3 metastases; no brain, bone or liver). In the investigational arm, nivo is administered 480mg IV q4 weeks with 1 dose prior to surgery followed by 9 adjuvant doses. The control arm is nephrectomy followed by standard of care surveillance. There is no placebo. Baseline tumor biopsy is required only in the nivo arm but encouraged in both. Randomized pts are stratified by clinical T stage, node positivity, and M stage. 805 pts provide 84.2% power to detect a 14.4% absolute benefit in recurrence-free survival at 5 years assuming the ASSURE historical control of ̃56% to 70% (HR = 0.70). The study is powered to evaluate a significant increase in OS (HR 0.67). Critical perioperative therapy considerations such as safety, feasibility, and quality of life metrics are integrated. PROSPER RCC embeds a wealth of translational studies to examine the contribution of the baseline immune milieu and neoadjuvant priming with anti-PD-1 on clinical outcomes. As of February 10, 2021, 704 patients have been enrolled (N = 805). Clinical trial information: NCT03055013.

TPS4597 Background: Non-clear cell renal cell carcinomas (nccRCC) account for approximately 25% of RCC patients (pts.). Data on treatment strategies for this heterogenous group of RCC are still limited, since most clinical trials focus on clear-cell RCC (ccRCC) histology. Recently combination therapies with immune checkpoint inhibitors (IO, avelumab or pembrolizumab) and tyrosinekinaseinhibitors (TKI) (axitinib) have been approved for treatment in RCC in all International Metastatic RCC Database Consortium (IMDC) risk groups. Additionally nivolumab and ipilimumab (IO/IO) has been approved for treatment in intermediate and high risk pts. showing a significant improvement in overall response rate (ORR), progression free (PFS), and overall survival (OS) compared to sunitinib. Moreover retrospective analysis in nccRCC pts. have shown promising results for IO-based therapies as well in these entities. Methods: In this prospective randomized phase-II multicenter European trial adults with advanced or metastatic nccRCC without prior systemic therapy are eligible. Other key inclusion criteria include: available tumor tissue, Karnofsky >70% and measurable disease per RECIST 1.1. All histological diagnoses are reviewed by a central pathologist. The study plans to randomize ̃306 pts. stratified for papillary or non-papillary non-clear cell histology and by the IMDC risk score. Pts. will be randomized 1:1 to either i) nivolumab 3mg/kg intravenously (IV) plus Ipilimumab 1mg/kg IV every 3 weeks for 4 doses followed by nivolumab fixed dose 240mg IV every 2 weeks or fixed dose 480mg IV every 4 weeks or ii) standard of care therapy according to the approved schedule. Treatment will be discontinued in case of unacceptable toxicity or withdrawal of informed consent. Pts may continue treatment beyond progression, if clinical benefit is achieved and treatment is well tolerated. Primary endpoint is the OS rate at 12 months. Secondary endpoints include OS rate at 6 and 18 months, median OS, PFS, ORR and quality of life. The trial is in progress and 214 patients (132 pts with papillary, 76 pts with non-papillary histology) have been enrolled until now. Clinical trial information: NCT03075423.

TPS5087 Background: Treatment options with minimal toxicity and novel mechanisms of action are urgently needed to improve clinical outcomes from mCRPC. Prostate-specific membrane antigen (PSMA)-targeted radioligand therapy (RLT) represents a new treatment for patients with PSMA-avid mCRPC. 177Lu-PNT2002 (also known as [Lu-177]-PSMA-I&T) is a PSMA-targeting agent and studies have shown demonstrable promising initial data. This trial seeks to prospectively evaluate the efficacy of 177Lu-PNT2002 for men with progressive mCRPC after androgen receptor axis-targeted (ARAT) therapy. Methods: This is a multi-center, open-label, phase III study. All patients must be at least 18 years of age, have documented progressive mCRPC at time of screening, high PSMA expression by PSMA PET/CT per blinded independent central review (BICR), chemotherapy naïve for CRPC and unfit or unwilling to receive chemotherapy. The study will commence with a 25-patient dosimetry lead-in. In the dosimetry phase, patients will receive up to four cycles of 177Lu-PNT2002 at 6.8 GBq every 8 weeks. In the randomization phase, approximately 390 patients will be randomized in a 2:1 ratio to receive 177Lu-PNT2002 (Arm A) versus enzalutamide or abiraterone (with prednisone or dexamethasone) (Arm B). Patients randomized to Arm B have an option to crossover to 177Lu-PNT2002 treatment after BICR-assessed radiologic progression. The primary endpoint is Radiological progression-free survival (rPFS) assessed by BICR using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 (soft tissue) and Prostate Cancer Working Group 3 (PCWG3) (bone) criteria. Key secondary endpoints include objective response rate, duration of response, PSA response, and overall survival. The study is powered at 90% to test the alternative hypothesis of a hazard ratio (HR) ≤ 0.66 at an α of 0.025. ClinicalTrials.gov identifier: NCT04647526. Clinical trial information: NCT04647526.

Published: June 2021

TPS5091 Background: Ra-223, a bone-targeted alpha therapy, prolongs survival in patients (pts) with symptomatic mCRPC to bone. Docetaxel targets microtubule trafficking improving survival in the mCRPC and metastatic hormone-sensitive settings. We hypothesized that simultaneously targeting the tumor and bone compartment yields superior outcomes than targeting either alone. We previously determined the dose and schedule of co-administering Ra-223 + docetaxel in a randomized phase I/IIa trial. The combination appeared to have improved declines in prostate specific antigen (PSA) and bone markers, delayed PSA progression, and was better tolerated (with adjusted dose/schedule) relative to standard docetaxel alone. We are now conducting a phase III study to determine the clinical benefit of the regimen. Methods: Randomization (1:1) of 738 men with mCRPC to docetaxel or docetaxel + Ra-223 is planned with a projected hazard ratio for treatment effect (15 vs 20 months median survival) of 0.75. Pts with ≥2 bone lesions and progression by Prostate Cancer Working Group 3 criteria are eligible. Other key inclusion criteria are an Eastern Cooperative Oncology Group performance status of 0–1 and normal organ function. Key exclusion criteria are: use of anticancer therapy ≤4 weeks (wks) before randomization and use of bone-seeking radiopharmaceuticals or chemotherapy in the castration-resistant setting, and bulky visceral metastases (≥3 lung and/or liver or a lesion ≥2 cm in the previous 8 wks). Subjects receive docetaxel 75 mg/m2 IV q3w for 10 doses or docetaxel 60 mg/m2 IV q3w for 10 doses + Ra-223 55 kBq/kg IV q6w for 6 doses. The primary endpoint is overall survival. Secondary and exploratory endpoints include: radiographic progression-free survival, symptomatic skeletal event-free survival, safety, markers of bone metabolism, alterations in circulating tumor cells and DNA, detection of androgen-receptor splice variant 7, changes in automated bone scan index (aBSI), and assessment of patient-reported outcome instruments (FACT-P, Brief Pain Inventory, Brief Fatigue Inventory). The study is open at 32 sites in the US and Netherlands and has 170 subjects enrolled. The study is sponsored by Memorial Sloan Kettering Cancer Center, and managed by the Prostate Cancer Clinical Trials Consortium. Clinical trial information: NCT03574571.

Published: June 2021

TPS5100 Background: NEPC is an aggressive cancer with poor prognosis. No standard treatment approach for NEPC exists and it remains an unmet need. NEPC is usually treatment-emergent, characterized by histological transformation from adenocarcinoma to a high-grade neuroendocrine tumor (NET), and may develop in 15%–20% of patients (pts) treated with standard prostate adenocarcinoma therapies, including novel hormonal therapies. The inhibitory Notch ligand, Delta-like ligand 3 (DLL3), is highly expressed on the surface of cancer cells, including NEPC cells, making it an attractive and a promising therapeutic target. AMG 757 is an HLE BiTE immuno-oncology therapy designed to redirect cytotoxic T cells to tumor cells by binding DLL3 on cancer cells and CD3 on T cells, resulting in T cell activation and expansion and T cell-dependent killing of tumor cells. AMG 757 showed in vitro activity in DLL3-expressing NETs, including NEPC. Preliminary results of an on-going first-in-human study suggest AMG 757 is safe and effective in pts with small cell lung cancer (NCT03319940), which prompted its study in NEPC. Methods: NCT04702737 is an open-label, phase 1b study evaluating AMG 757 infusion in pts with metastatic de novo or treatment-emergent NEPC, consisting of dose exploration and then dose expansion. Key eligibility criteria include adults (≥18 y) with NEPC whose disease progressed/recurred after ≥1 treatment course including a platinum-based regimen for de novo NEPC or an androgen signaling inhibitor, measurable disease per modified RECIST 1.1 per Prostate Cancer Working Group 3 modifications, ECOG performance status ≤2, life expectancy > 3 mo, adequate organ function, and no untreated/symptomatic brain metastases. Primary objectives are to evaluate safety and tolerability and determine the maximum tolerated dose or recommended phase 2 dose of AMG 757. Secondary objectives are to evaluate antitumor activity (ie, objective response, duration of response, progression-free survival, overall response) and characterize pharmacokinetics. The starting dose for dose exploration will be based on the dose deemed safe and tolerable in the ongoing trial of AMG 757 in SCLC. The study is open to enrollment. Clinical trial information: NCT04702737.
