e24214 Background: Androgen deprivation therapy (ADT) increases the risk of developing depression which can affect quality of life and adherence to treatment. Depression has been associated to inflammation in patients with cancer. Albumin and neutrophil-to-lymphocyte ratio (NLR) are inflammatory biomarkers that to our knowledge have not been evaluated in hormone mediated depression in prostate cancer (PC). The aim of this study is to evaluate the severity of hormone related depression and its association with inflammatory biomarkers, demographics, and cancer treatment variables and to determine antidepressant treatment response. Methods: A retrospective chart review of consecutive referrals to psycho-oncology of PC patients on ADT with new onset depression was conducted. Demographics, cancer and psychiatric history, and laboratories within 1 week of initial visit were collected. Assessments for depression included clinical interview and patient-rated scale [Beck Depression Inventory (BDI)]. These measures were done at baseline (before starting an antidepressant) and follow-up to determine treatment response. Successful antidepressant treatment response is defined as ≥50% reduction in baseline BDI score. Statistical analysis comparing the association of clinical variables between depression, inflammatory biomarkers, and demographics included Pearson’s correlation, chi-square, ANOVA, t-test, and binary logistic regression was used to determine associations with depression. Data was dichotomized using median split for inflammatory biomarkers due to skewness. Results: A sample of 26 PC patients on leuprolide (mean age 70 years; 13 Hispanic, 13 non-Hispanic) included 13 with mild depression (BDI£20) and 13 with moderate- to-severe depression (BDI>20). Moderate-to-severe depression was associated with higher NLR (≥3, p= .041), stage IV PC (n=15, p= .001), and Hispanics ( p= .033). Lower albumin (£3.9) was associated with higher age ( p= .007), higher NLR ( p= .006), and non-Hispanics ( p= .049) but not depression. Over 54% (13/24) of patients did not respond to antidepressant treatment. In logistic regression only NLR and Stage IV PC remained significantly associated with depression after adjusting for confounding variables. Conclusions: NLR and stage IV PC were both associated with moderate-to-severe depression. These results are likely due to increased level of inflammation in advanced cancer. Inflammation has been associated with treatment resistant depression which could explain why 54% of patients did not respond to antidepressant treatment. NLR is an inexpensive routinely used test in cancer centers that has the potential to be used as a biomarker of severity of depression in PC patients.

TPS10068 Background: Survival for high-risk neuroblastoma (NBL) remains poor with over 50% of patients experiencing disease relapse. The addition of dinutuximab (DIN) and granulocyte macrophage colony-stimulating factor (GM-CSF) to irinotecan (IRN) and temozolomide (TMZ) in patients with first relapse achieved an overall response rate of 42% in the study ANBL12211 and is now standard of care. However, there remains a significant unmet need to improve outcomes for children with relapsed/refractory NBL. Deregulation of the Cyclin D/cyclin-dependent kinase (CDK) 4 & 6 pathway has been observed in NBL, rendering CDK4 & 6 inhibition logical to explore. Abemaciclib is an orally administered, selective CDK4 & 6 inhibitor approved to treat breast cancer. JPCS (NCT04238819) is designed to assess the pharmacokinetics, safety, and tolerability of abemaciclib added to standard treatment regimens for relapsed/refractory pediatric solid tumors. Part A defined the recommended phase 2 dose (RP2D) of abemaciclib in combination with IRN and TMZ. In Part C, the addition of DIN + GM-CSF to the JPCS Part A regimen will be evaluated. The co-primary objectives of Part C are to determine the RP2D and to estimate the anti-tumor activity of abemaciclib added to the ANBL1221 chemoimmunotherapy backbone in patients with first relapse/refractory NBL. Methods: JPCS Part C is a two-stage, non-randomized, open-label, Phase 1b/2 study for patients < 21 years of age with first relapse/refractory NBL. Stage 1 aims to identify the maximum tolerated dose (MTD) of abemaciclib at a starting dose of 55 mg/m2 combined with DIN, GM-CSF, IRN and TMZ using a 3+3 design. One dose de-escalation (30 mg/m2) will be possible if the starting dose is not tolerated. Further tolerability and initial anti-tumor activity will be evaluated in an expansion cohort at the MTD. Up to 11 evaluable patients will enroll in Stage 1 at the MTD; the MTD will be declared the RP2D if adequate safety and tolerability are observed and ≥6 patients achieve minimal response or better per International Neuroblastoma Response Criteria (INRC). Following determination of the RP2D, Stage 2 will enroll 35 patients. If ≥26 of 46 total patients achieve an INRC minimum response or better, further investigation of this regimen could be warranted. As of 31 Jan 2023, Part C is open for enrollment at one site (US) and additional sites are being evaluated. References: Mody et al. J Clin Oncol. 2020;38(19):2160-2169.

TPS10073 Background: Intravenous irinotecan hydrochloride (IRN-IV) is approved for the treatment of adult colorectal cancer and also used off-label to treat a range of adult and pediatric tumors including recurrent Ewing sarcoma, rhabdomyosarcoma, neuroblastoma, hepatoblastoma, Wilms tumor, gynecologic cancers, lung cancer and medulloblastoma. Previously, a regimen of IRN-IV administered as a 60-min i.v. infusion daily for 5 days, bi-weekly in combination with other agents such as temozolomide has been recommended use in treating children with solid tumors (Blaney. ClinCanRes, 2001). Protracted administration schedule of IRN-IV is inconvenient for patients, so oral regimens utilizing IRN-IV have been developed and implemented with favorable tumor response (Wagner. ClinSarcRes, 2015). Unfortunately, the palatability of the IRN-IV is poor, leading to reduced compliance especially in younger pediatric patients. Development of an advanced formulation to improve tolerability and patient compliance is an important unmet need. VAL-413 is a novel formulation developed to improve palatability of oral irinotecan. This pilot trial will examine the safety and tolerability of this novel formulation and assess pharmacokinetics compared to current oral regimen. Methods: Eligibility: Up to 20 patients ≥ 1 year of age or ≤ 30 years of age with recurrent pediatric solid tumors and adequate bone marrow, renal and liver function, for whom irinotecan therapy is a treatment option will be enrolled. Trial Design: Two different dose levels of VAL-413, 90mg/m2/day or 110mg/m2/day will be studied in combination with fixed-dose temozolomide using a standard 3 + 3 phase I design. In the event the starting dose of 90 mg/m2/day is not tolerable due to toxicity, a lower dose of 75 mg/m2/day may be implemented. Treatment: During the first cycle of treatment, each patient will receive 4 daily doses of VAL-413 and one daily dose of the intravenous preparation of irinotecan taken orally (IRN-IVPO). During all subsequent cycles, only VAL-413 will be given with temozolomide in 5-day courses administered every 21 days, as tolerated. Outcome Measures:Toxicity is assessed by NCI CCTCAEv5; tumor response is assessed by RECIST 1.1. A palatability survey instrument will assess palatability of VAL-413 vs. IRN-IVPO; comparative intra-patient pharmacokinetics of irinotecan and its metabolites will be assessed. This trial is ongoing (CT.gov: NCT04337177), with no DLT observed to date. Clinical trial information: NCT04337177 .

Published: June 2023

TPS10638 Background: Hereditary breast and colorectal cancers accounts for 5-10% of all cases, but less than half of all eligible patients undergo NCCN guideline-concordant screening. This proportion is even lower among Black patients, who have a higher breast cancer and colorectal incidence and mortality. Recruitment through community organizations has been shown to identify patients who are eligible for genetic testing but have not been offered it by their doctor. Our one-page cancer genetic risk assessment (CGRA) and telegenetics were previously shown to improve adherence to genetic testing guidelines for hereditary breast and ovarian cancer. Our objective is to identify adults eligible for hereditary breast and colorectal cancer syndromes genetic testing using trusted community organizations that serve the Black community as entry points, reach them with our tailored program, and measure impact. Methods: In this prospective single-arm trial, adults of > 18 years old who self-identify as Black or African American are recruited during events put together by community organizations in Houston, Texas. The CGRA was modified to encompass hereditary breast and colorectal cancer syndromes based on NCCN guidelines. To improve convenience, eligible participants can be consented and fill out the CGRA in-person or via QR code link using a smart phone. Study team members attend community events and are also available via phone to help with informed consent, CGRA, etc. Those at high risk for hereditary breast and colorectal cancer syndromes are provided with educational materials and can be sent the saliva-based kit or complete it on-site. When results of genetic testing include a pathogenic mutation (PV) or variant of uncertain significance, individuals receive telegenetic counseling and risk reduction resources, including about cascade genetic testing. Others are notified of negative results. The program includes education for interested community organization members about importance of genetic testing. The program is projected to reach 1,000 participants with 300 completing genetic testing and identification of 11 PV. The study is overseen by a Community Advisory Board. Impact will be evaluated via a multiple methods design using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) Qualitative Evaluation for Systematic Translation (QuEST) framework six months after program start. Quantitative data will be analyzed using descriptive statistics and standard tests of association. Data collected via semi-structured interviews with participants and program implementers will be audio-recorded, transcribed, double-coded, and analyzed via thematic analysis. Enrollment started December of 2022. 15 participants patients enrolled during two community events. Clinical trial information: NCT05694559 .

TPS1115 Background: The current first-line (1L) standard of care (SOC) for human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC) is trastuzumab (T) plus pertuzumab (P) and a taxane. Despite advances in 1L SOC, most patients progress during maintenance therapy with T + P. Tucatinib is a tyrosine kinase inhibitor (TKI) approved in combination with T and capecitabine for adults with HER2+ MBC, with and without brain metastases (BM). In HER2CLIMB, the addition of tucatinib significantly prolonged progression-free survival (PFS) and overall survival (OS) in patients with HER2+ MBC and was well tolerated. Adding tucatinib also reduced the risk of disease progression or death in patients with untreated and/or active BM (Murthy et al. 2020, Curigliano et al. 2021). HER2CLIMB-05 investigates whether adding tucatinib to 1L SOC as maintenance therapy will extend PFS while maintaining quality of life (QOL). Methods: HER2CLIMB-05 (NCT05132582) is a phase 3, randomized, double-blind study evaluating tucatinib plus T + P as maintenance therapy for HER2+ MBC. Approximately 650 patients will be enrolled. Eligible patients will have advanced HER2+ disease, no progression on 4–8 cycles of prior 1L SOC, Eastern Cooperative Oncology Group Performance Status of 0 or 1, and no or asymptomatic BM. Exclusion criteria include prior treatment with anti-HER2 and/or anti-epidermal growth factor receptor TKI (prior SOC for early BC is permitted) or inability to undergo contrast magnetic resonance imaging of the brain. Patients will be randomized 1:1 to receive either tucatinib or placebo twice daily, with T + P once every 21 days. Patients with hormone receptor-positive disease may receive endocrine therapy. The primary endpoint is investigator-assessed PFS. Secondary endpoints include OS (key endpoint), PFS by Blinded Independent Central Review (BICR), time to deterioration of health-related QOL, central nervous system PFS, safety, and pharmacokinetic (PK) parameters. PFS and OS will be compared using a 2-sided stratified log-rank test between treatment groups. Time-to-event endpoints will be summarized using the Kaplan–Meier method. PK and safety data will be summarized using descriptive statistics. Enrollment is ongoing in the US, Canada, Brazil, APAC and EU countries with additional sites planned.

TPS1118 Background: Patients who receive frontline CDK4/6 inhibitor (CDK4/6i) therapy eventually experience disease progression. Resistance to CDK4/6i is likely a transient adaptive mechanism that may be reversed by inhibition of the PI3K/mTOR pathway. Thus, combination of CDK4/6i and PI3K/mTORi after disease progression on CDK4/6i could restore sensitivity to CDK4/6i and prevent activation of the PI3K/mTOR pathway. This hypothesis was evaluated in a Phase 1b study (Layman SABCS 2021) of gedatolisib (geda), a potent inhibitor of PI3K and mTOR. Subjects with HR+/HER2- ABC with prior CDK4/6i received geda (180 mg IV weekly for 3 weeks, then one week off) with palbociclib (palbo) and fulvestrant (FUL). Median PFS was 12.9 months with 63% overall response rate. Efficacy was observed regardless of PIK3CA mutation status (Wesolowski SABCS 2022). Geda was well tolerated, with few discontinuations due to treatment-related adverse events (4%). The most common AE was stomatitis; hyperglycemia of any grade occurred in 26% of patients. This preliminary data, dosing schedule, and study population characteristics form the basis for the Phase 3 trial, VIKTORIA-1 (NCT05501886). Methods: This Phase 3 multinational clinical trial will evaluate geda and FULwith or without palboin patients with HR+/HER2- ABC previously treated with any CDK4/6i in combination with a non-steroidal aromatase inhibitor (AI) therapy. Those without tumor PIK3CA mutations will be assigned to Study 1 (n=351) and randomized to Arm A (geda, palbo, and FUL), Arm B (geda and FUL), or Arm C (FUL). Those with PIK3CA mutations will be assigned to Study 2 (n=350) and randomized to Arm D (geda, palbo, and FUL), Arm E (alpelisib and FUL), or Arm F (geda and FUL). Key eligibility criteria include adults with confirmed metastatic or locally advanced breast cancer, any menopausal status, radiologically evaluable disease, and prior CDK4/6i treatment in combination with a non-steroidal AI. Prior hormonal therapy, including SERDs, is allowed. Key exclusion criteria include prior treatment with a PI3K, Akt, or mTOR inhibitor, prior treatment with chemotherapy for advanced disease, more than two lines of prior endocrine therapy, bone only disease with no soft tissue components, active CNS metastases, and type 1 diabetes or uncontrolled type 2 diabetes. The primary endpoint is PFS assessed by blinded independent central review per RECIST v1.1. Secondary endpoints included overall survival, safety and tolerability, ORR, duration of response, time to response, CBR, quality of life, and pharmacokinetics. The trial is open for enrollment.

TPS1120 Background: Eftilagimod alpha (efti), a soluble LAG-3 protein, acts as an MHC class II agonist that enhances immunity by mediating antigen presenting cell and CD8 T-cell activation. Data from a randomized, phase 2b trial of efti plus paclitaxel compared to placebo plus paclitaxel in patients (pts) with HR+ HER2– metastatic breast cancer (MBC) (AIPAC; NCT02614833) showed sustained pharmacodynamic activity that was linked to improved overall survival (OS) in the efti arm. AIPAC-003 is a randomized, double-blind, placebo-controlled phase 3 trial testing efti plus paclitaxel in HER2-neg/low MBC pts, including an initial open-label dose optimization lead-in (DOL) component to determine the optimal biological dose (OBD) of efti in this combination. Methods: Enrolment for the DOL will begin in March 2023 in max. 66 pts. Primary endpoints (EP) in the DOL include safety and tolerability of 90 mg vs 30 mg efti and defining the OBD of efti in combination with weekly paclitaxel. Determination of the OBD will be based on the totality of safety and tolerability data together with overall response rate (ORR) and pharmacodynamic marker (CD8+ T cells, absolute lymphocyte count) data. In the Phase 3 component approx. 771 pts are randomized to receive either paclitaxel + efti or paclitaxel + placebo in a double-blinded fashion. The primary EP for the proposed Phase 3 is OS. Key secondary EPs include progression free survival and ORR by RECIST 1.1, quality of life and safety. Pts will receive paclitaxel (80 mg/m2 I.V. on D1, 8 and 15 in a 4-week cycle), followed by efti or placebo (DOL: 30 or 90 mg efti; Phase 3: OBD of efti or placebo) S.C. on D1 and 15 in a 4-week cycle for up to 12 months. Key inclusion criteria: Pts with either a) HR+ and HER2-neg/low and endocrine therapy-resistant MBC or b) TNBC not eligible for anti-PD-1-based therapy. Pts must have measurable disease, ECOG PS 0-1 and no prior chemo for metastatic disease.

TPS1121 Background: ARV-471, an oral PROTAC ER degrader, was well tolerated and showed evidence of clinical activity in a phase 1/2 study in heavily pretreated patients with ER+/human epidermal growth factor receptor 2 (HER2)- advanced breast cancer. The CDK4/6 inhibitors abemaciclib and ribociclib are approved in combination with endocrine therapy as first- and second-line treatment for ER+/HER2- advanced or metastatic breast cancer; abemaciclib is also approved as monotherapy and in combination with other agents in additional breast cancer settings. ARV-471 combined with abemaciclib or ribociclib showed evidence of synergistic interactions in ER+ breast cancer cells and greater tumor growth inhibition in a xenograft breast cancer model compared with fulvestrant in combination with these agents. Here we describe the first sub-studies of the open-label, phase 1b/2 TACTIVE-U umbrella study, which evaluate the safety and clinical activity of ARV-471 plus abemaciclib (sub-study A; NCT05548127) and ribociclib (sub-study B; NCT05573555) in patients with ER+/HER2- advanced or metastatic breast cancer. Future combination sub-studies will be included in TACTIVE-U. Methods: Patients eligible for sub-studies A and B are aged ≥18 years, have histologically or cytologically confirmed ER+/HER2- advanced or metastatic breast cancer not amenable to surgical resection with ≥1 measurable lesion by RECIST 1.1, and have received ≤2 lines of prior therapy for advanced or metastatic disease and 1 line of any CDK4/6 inhibitor–based regimen in any setting. In sub-studies A and B, patients will receive ARV-471 orally once daily (QD) continuously in a dose escalation/de-escalation approach. In sub-study A, abemaciclib will be given orally twice daily continuously, and in sub-study B, ribociclib will be given orally QD for 21 days followed by 7 days off treatment. For both sub-studies, the primary endpoint of the phase 1b portion is dose-limiting toxicities to determine the recommended phase 2 dose of ARV-471 in combination with abemaciclib or ribociclib. Secondary endpoints of phase 1b are antitumor activity (overall response rate [ORR], clinical benefit rate [CBR], and duration of response [DOR]), progression free survival (PFS), safety (type, frequency, and severity of adverse events and laboratory abnormalities), and plasma concentrations of study drugs. Phase 2 further evaluates the antitumor activity of the combinations; the primary endpoint is ORR and secondary endpoints include antitumor activity (CBR and DOR), PFS, overall survival, safety, plasma concentration of study drugs, and changes in circulating tumor DNA.
