TPS1123 Background: TTK (Threonine Tyrosine Kinase also known as Monopolar spindle 1 [Mps1]), is a dual-specificity serine-threonine kinase critical for anaphase promoting complex/cyclosome inhibition at the spindle assembly checkpoint, and is required for chromosome alignment and error correction. Inhibition of TTK causes cells to prematurely exit mitosis with unattached chromosomes, resulting in aneuploidy and cell death. Higher TTK tumor levels correlate with worse prognosis and may contribute to the survival and proliferation of aneuploid cells. CFI-402257, a potent and selective inhibitor of TTK inhibits the growth of a variety of human cancer-derived cell lines with IC50 of 8-40 nM. A first-in-human phase 1 study of CFI-402257 administered orally as a single agent, demonstrated a tolerable safety profile and evidence of clinical activity in patients with advanced solid tumors. The MTD was 168 mg daily, and the study expanded to 3 cohorts: solid tumors, HER2-negative breast cancer, and hormone receptor positive (HR+/HER2-) breast cancer in combination with fulvestrant. The dose limiting toxicity was manageable and reversible dose-dependent neutropenia. Investigator-confirmed partial responses (cPR) were observed in 5 patients (10.6%) with 25 (53.2%) exhibiting disease control. In the HR+/HER2- breast cancer population previously treated with cyclin dependent kinase 4/6 inhibitors (CDK4/6i) and aromatase inhibitors, there were 4 cPR’s with a median duration of response of 256 days, with responses emerging after 2 cycles of therapy. Responses were observed with CFI-402257 as a single agent and in combination with fulvestrant. Based on these data, study TWT-203 will focus on advanced solid tumors and advanced HR+/HER2- breast cancers in combination with an approved endocrine therapy. Methods: Safety and clinical activity of CFI-402257 monotherapy will be evaluated in patients with advanced solid tumors (Part A) or in combination with fulvestrant in patients with HR+/HER2- advanced breast cancer (Part B). Part A will confirm the RP2D using a 3+3 design with a starting dose of 126 mg daily. Part B evaluates CFI-402257 in combination with fulvestrant in patients with HR+/HER2- advanced breast cancer following progression on prior CDK4/6i and endocrine therapy. Initially 6 patients will be treated with CFI-402257 and fulvestrant, and safety, tolerability, and PK evaluated, with further expansion to confirm the RP2D and characterize CFI-402257 activity. Efficacy endpoints include overall response rate and disease control rate. Safety endpoints include incidence of treatment emergent adverse events. Exploratory objectives include characterization of protein and molecular alterations relevant to the cell cycle and CFI-402257 response.

TPS1125 Background: Triple-negative breast cancer (TNBC) is the subtype of breast cancer with the worst prognosis and is the subtype most often associated with germline mutations of BRCA1 and certain other genes. Alpha-lactalbumin (aLA) is a milk protein that is expressed in lactating breasts but not at other times or in other normal tissues. Expression of aLA is found in approximately 70% of TNBC (Cancers PMID: 27322324) so is an attractive immunologic target for TNBC based on the “retired protein hypothesis” (Semin Immunol PMID: 31926646). Pre-clinical studies have shown that vaccination with aLA provides treatment of established and, more potently, protection from development of autochthonous tumors in transgenic murine models of breast cancer and against 4T1 transplantable breast cancer in BALB/c mice (Nat Med PMID: 20512124). We are conducting a Phase I trial in patients with early stage TNBC to demonstrate the safety of this approach and to document the ability to produce a meaningful immunologic response to aLA. Methods: Patients with ER-negative, PR-negative, HER2-negative breast cancer of pathologic stage I-III or who had residual disease after standard pre-operative systemic therapy are being entered into a Phase I trial of alpha-lactalbumin with a GMP-grade zymosan adjuvant in Montanide ISA 51 VG vehicle. Participants must be within 3 years of initiation of treatment and have no evidence of recurrence. Patients receive a total of 3 vaccinations administered once every 2 weeks with doses escalated using a 3+3 trial design. Toxic events of Common Terminology Criteria for Adverse Events (CTCAE) grade 2 or greater are considered dose-limiting. Dose levels being tested are alpha-lactalbumin/zymosan 0.01 mg/0.01 mg, 0.1 mg/0.1 mg, and 1 mg/1 mg. Patients are being monitored for toxicity until 84 days after the first vaccination or resolution of toxicity, whichever is later. Blood is being drawn prior to therapy and 14, 28, and 56 days after the first vaccination to assess cellular response using enzyme-linked immunosorbent spot (ELISpot) assays of interferon-gamma and interleukin-17 production in response to aLA. Humoral response to aLA vaccination is being assessed by enzyme-linked immunosorbent assay (ELISA). After identification of the Maximum Tolerated Dose we will expand the dose levels associated with effective tumor immunity and enroll a cohort of patients without cancer planning to undergo prophylactic bilateral mastectomy.

Evaluation of a three-part equity intervention for women of color with breast cancer.
Authors: Rivers Jamil , Robles-Rodríguez Evelyn 
Published: June 2022

TPS1129 Background: Women of color (WOC) with breast cancer miss and fail key points in care due to racial disparities in cancer services. Conscious and unconscious bias means that these women are not treated in a timely way or as rigorously. They are offered fewer options, and the patient navigation and education needed for them to self-advocate is ignored. Black women in particular have the highest breast cancer death rates. Care delivery differs even independent of such variables as literacy, income, and education. Separately and incrementally, findings to date have shown the potential oof patient navigation, equity assessment, and mobile support to reverse these disparities. In pilot investigations –– partnering with academic cancer centers –– The Chrysalis Initiative (a nonprofit patient advocacy and research organization) has validated the potential of combining these approaches in a three-part intervention. Based on preliminary work, it is hypothesized patients will: experience significantly greater adherence to the recommended continuum of care, without disruption or barriers; more often seek second opinions and additional supportive resources, and engage in clinical trials; demonstrate less co-morbidities, through more preventive measures and healthful lifestyle; suffer fewer interactions perceived to be influenced by racism; undergo less financial distress, with guidance on managing and planning costs; feel more confident and more optimistic in their outlook; and achieve better clinical results and lower costs. Methods: To determine and document the full impact, both quantitatively and qualitatively, of the experimental three-part intervention, the trial is: delivering navigation/coaching services to the study population, using counselors who are predominantly WOC who have experienced the challenges of breast cancer care. Surveys and interviews pre- and post-intervention will add to impact measures; providing the experimental group with the BC Navi App on both iOS and Android devices . Developed in partnership with InTouch, the app supports engagement and tracking. It provides a dashboard for care evaluation to supplement EMR data; conducting an equity assessment of breast cancer services of partnering clinical programs through use of focus groups with staff, patients, and community; procedural checks; and data collection from center EHR systems. The review audits 40 domains of care based on NCCI, NCI, ASCO, ACR, and other standards. The assessment team works closely and collaboratively with each cancer center’s clinical and administrative staff to reveal disparities and find consensus on ways to close gaps. This trial in progress is randomizing 200 subjects to the coaching/mobile app intervention arm and 100 to benefits of the equity assessment only, with comparison to nonWOC with breast cancer. The trial aims to disseminate the three-part intervention in easily reproducible form.

TPS12145 Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect in cancer survivors that can last long after completion of neurotoxic chemotherapy. Patients with CIPN often experience neuropathy symptoms such as pain, tingling, numbness, paresthesia, and dysesthesia, which can lead to significant functional decline and diminished quality of life (QoL). Our prior study showed that more than half of breast cancer survivors who received taxane-based chemotherapy experienced persistent peripheral neuropathy symptoms for a mean duration of 5.6 years after completing chemotherapy. This outcome highlights the importance of developing effective CIPN treatments to improve cancer survivors’ QoL. Identifying nonpharmacological approaches to reduce CIPN symptoms and improve cancer survivors’ outcomes is urgently needed. Acupuncture is a widely used, minimally invasive Traditional Chinese Medicine technique that has shown promising evidence as an effective and safe treatment for CIPN. We hypothesize that acupuncture may reduce CIPN pain and improve overall CIPN symptoms in cancer survivors. Methods: We are conducting a two-arm, parallel randomized clinical trial comparing electroacupunture (EA) versus sham acupuncture (SA) in cancer survivors at Memorial Sloan Kettering Cancer Center, New York, NY. The EA arm includes a total of ten sessions of EA over eight weeks using a standardized, semi-fixed protocol developed by our group based on the previously published pilot study (NCT03183037). The SA arm includes a sham technique that uses a combination of non-acupuncture points and a non-insertion procedure in ten sessions over eight weeks. The primary outcome of this study is the Brief Pain Inventory-Short Form (BPI-SF) average pain item. The secondary outcomes are quantitative sensory testing measures and additional patient-reported outcomes that include the BPI-SF pain interference subscale, Neuropathic Pain Scale (NPS), Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx), CIPN-20, PROMIS Global Health Scale, and Patients’ Global Impression of Change (PGIC). The primary end point is week 12 and the secondary end point is week 24; treatment effects are assessed at baseline and at weeks 4, 8, 12, 18, and 24. Eligibility criteria includes: 1) Moderate-to-severe CIPN pain, defined by a score of 4 or greater on a 0–10 numeric rating scale; 2) completion of neurotoxic chemotherapy at least three months prior to enrollment; and 3) no changes in anti-neuropathy medications within three months of enrollment. We have accrued 30 participants as of February 2022, with a total accrual target of 250 participants. Accrual completion is anticipated by December 2024. Funding resource: NIH R37 CA248563.

Published: June 2022

TPS1598 Background: In the US, many of the 90,000 adolescents and young adults (AYAs) (i.e., individuals ages 15-39) diagnosed with cancer each year do not receive services to address the range of needs they experience during cancer treatment. AYAs’ unmet needs are associated with higher distress, poorer health-related quality of life, and higher physical symptom burden. However, AYAs often do not use services available to them through their cancer programs, even when they face no access issues (e.g., cost, insurance status, local service capacity). AYAs report barriers to service use including lack of awareness, challenges navigating large volumes of information and complex health systems, and hesitance to broach needs with providers without prompting. To facilitate a systematic and patient-centered approach to addressing AYAs' unmet needs, we leveraged user-centered design to develop the AYA Needs Assessment & Service Bridge (NA-SB). NA-SB includes a patient-reported outcome measure assessing AYAs’ physical, psychosocial, and practical needs, and a collection of referral pathways for connecting AYAs to services based on the needs they report. In this feasibility pilot study, we are evaluating the implementation of NA-SB in the University of North Carolina Lineberger Comprehensive Cancer Center (UNC) AYA Cancer Program. Methods: Eligible participants include AYAs ages 18-39 currently undergoing cancer treatment at UNC (n = 25-50). The needs assessment portion of NA-SB is administered electronically through REDCap during routine clinical encounters with the AYA team. After an AYA completes the needs assessment, an AYA provider (i.e., social worker/nurse practitioner) reviews their responses and initiates referral pathways. Six weeks following their completion of the needs assessment, AYAs complete a survey assessing their perceptions of (1) the usability of the NA-SB needs assessment, (2) the feasibility, acceptability, and appropriateness of implementing NA-SB, and (3) the extent to which their needs have been met. We are also assessing participating providers’ perceptions of NA-SB’s implementation through periodic check-in calls. Results: We will report descriptive statistics on participant demographics, needs reported, and quantitative outcomes. We will analyze data from provider check-in calls inductively to further elaborate on implementation experiences and determinants. Conclusion: By harnessing patient-reported data to facilitate care coordination for AYAs, NA-SB has the potential to improve processes of care and subsequent outcomes for AYAs, an underserved and understudied population. This pilot study represents a critical first step towards translating NA-SB into routine cancer care for AYAs. Clinical trial information: NCT04586127.

TPS2082 Background: H3 K27M-mutant diffuse midline glioma is a universally fatal malignancy primarily affecting children and young adults; while radiotherapy (RT) provides transient benefit, no effective systemic therapy is currently available. ONC201, a first-in-class imipridone, is an oral, blood-brain barrier penetrating, selective small molecule antagonist of dopamine receptor D2/3 and agonist of the mitochondrial protease ClpP. Previously, ONC201 monotherapy demonstrated durable objective responses in adults with recurrent H3 K27M-mutant glioma. This phase 1 trial was designed to evaluate ONC201±RT in pediatric patients with H3 K27M-mutant midline glioma DIPG. Methods: This multicenter, open-label, dose escalation and expansion phase 1 study of ONC201 is comprised of eight arms that will evaluate the recommended phase 2 dose (RP2D) of ONC201, biomarkers, and pharmacokinetics (PK) of ONC201±RT in various treatment settings. Arm G previously defined the RP2D for ONC201 administered twice weekly on consecutive days in patients with H3 K27M-mutant glioma who had completed radiotherapy. Arm H, for which enrollment is ongoing, will estimate the influence of tumor location and blood-brain barrier integrity on PK and intratumoral ONC201 exposure in biopsy-eligible pediatric tumors (DIPG or contrast-enhancing thalamic glioma). Patients eligible for Arm H will be aged 2-≤19 years, ≥2 weeks from last RT administration, and have a Karnofsky/Lansky performance score ≥50; prior confirmation of H3 K27M mutation is not required. In Arm H, single-agent ONC201 administration will occur on two consecutive days each week during each 21-day cycle at the RP2D defined in Arm G. Evidence of disease progression is not required; as such, ONC201 may be administered in the maintenance setting or for recurrent disease. Arm H has a planned enrollment of 27 patients. Each patient will undergo biopsy at a single prespecified biopsy window, which will be assigned at enrollment (Table); plasma for PK analysis will be collected from all patients at all time points shown in the Table, with additional collection pre-dose and 0.5 h post first dose. Clinical trial information: NCT03416530. [Table: see text]
Trial in progress: A phase 1-2, first-in-human, open label, dose escalation and expansion study of AU-007, a monoclonal antibody that binds to IL-2 and inhibits IL-2Rα binding, in patients with advanced solid tumors.

Published: June 2022

TPS2671 Background: AU-007 is a computationally designed, monoclonal antibody that binds to IL-2 on its CD25 binding epitope. AU-007 bound IL-2 (A/IL-2) cannot bind to high affinity trimeric IL-2 receptors (IL-2R) consisting of CD25, CD122, and CD132 expressed on Tregs and vascular endothelium, but its binding to low affinity dimeric IL-2Rs (CD122 and CD132) expressed on T effector and NK cells is unhindered. Thus, AU-007 redirects endogenously produced or exogenous IL-2 (aldesleukin) towards activation of immune stimulating T effector and NK cells, while diminishing Treg activation and expansion. AU-007 will also bind and redirect newly secreted endogenous IL-2 resulting from A/IL-2 driven T cell expansion in the tumor, converting a Treg mediated autoinhibitory loop into an immune stimulating loop. AU-007 is unique in the IL-2 therapeutic field as engineered exogenous, recombinant “non-CD25” IL-2s in development cannot address the autoinhibitory effect of endogenous IL-2. Preclinically, AU-007 has been demonstrated to capture endogenous human IL-2 in vivo. AU-007 with a single low dose of IL-2 has demonstrated efficacy in multiple cancer models and has an excellent safety profile in non-human primates. Methods: This first-in-human, multicenter, open label Phase 1- 2 study evaluates the safety, tolerability, and initial efficacy of AU-007 +/- aldesleukin in patients with advanced solid tumors (CT-2021-CTN-03938-1). Phase 1 consists of 3 escalation arms each starting with a single 1+2 escalation cohort followed by 3+3 escalation cohorts to define the recommended Phase 2 dose (RP2D) or maximum tolerated dose (MTD). Patients with melanoma, renal cell carcinoma (RCC) and 17 selected solid tumors are eligible. Prior treatment with check point inhibitors is allowed. In Arm A, escalating doses of Q2w AU-007 are evaluated in sequential escalation cohorts. In Arm B, a single dose of aldesleukin is given with the initial AU-007 dose. AU-007 is given at a fixed dose Q2w with an escalating single aldesleukin dose in sequential escalation cohorts. In Arm C, AU-007 is evaluated in combination with aldesleukin, both given Q2w. AU-007 is administered at a fixed dose with an escalating dose of aldesleukin in sequential cohorts. The Phase 2 cohort expansion portion of the study evaluates the initial efficacy at the RP2D defined in escalation cohorts A, B, and C in 3 matching expansion cohorts of up to 20 patients each. Patients with advanced melanoma, RCC and other tumors including, but not limited to, Merkel Cell Carcinoma, NSCLC, and urothelial cancer are eligible. Enrolment to the study commences in Australia, with US sites planned to open later in 2022. Clinical trial information: CT-2021-CTN-03938-1.

Published: June 2022

TPS2693 Background: M2-like macrophages are thought to promote an immunoinhibitory environment and prevent activation and proliferation of T cells, leading to resistance to checkpoint inhibitor (CPI) therapy. OR2805 is a fully human monoclonal antibody identified in a patient who had an exceptional response to CPI. OR2805 recognizes CD163, an immunosuppressive scavenger receptor highly expressed on M2 tumor-associated macrophages (TAMs). OR2805 treatment reprograms M2 macrophages to take on an immunostimulatory, M1-like phenotype. In macrophage/T cell coculture assays, OR2805 treatment relieved the suppressive effect of M2c macrophages as demonstrated by increased T-cell proliferation and stimulation of IFN-γ and perforin release. OR2805 restored the IFN-γ production of exhausted T cells and showed a synergistic effect on cocultures treated in combination with CPI. OR2805 monotherapy demonstrated significant anti-tumor activity in lung cancer xenograft models in NSG-SGM3 mice. Relieving the immune suppression of CD163-expressing TAMs by OR2805 to improve anti-tumor T-cell responses will be evaluated alone and in combination with CPI therapy. Methods: This phase 1/2, open-label, multicenter, dose-escalation/expansion study is assessing the safety, tolerability and preliminary activity of OR2805 alone and in combination with anti-PD-1 or chemotherapy in up to 325 adults (≥18 years) with histologically or cytologically confirmed metastatic or locally advanced solid tumors. The study is divided into 3 parts. Part A will enroll subjects with advanced solid tumors of any histology to describe the preliminary safety profile of OR2805 and determine the recommended phase 2 dose (RP2D) of OR2805 alone and in combination with an anti-PD-1 monoclonal antibody. Part B will further characterize the safety and preliminary antitumor activity of OR2805 either alone or in combination with an anti-PD-1 or chemotherapy in previously treated non-small cell lung cancer (NSCLC), melanoma and liposarcoma, as well as in previously untreated NSCLC in combination with an anti-PD-1 antibody. Part C will evaluate OR2805 monotherapy in relapsed squamous cell carcinoma of the head and neck and other tumor types with an emphasis on correlative biomarker analysis. OR2805 will be infused on Day 1 of 21-day cycles. Primary endpoints are adverse events, laboratory abnormalities, dose-limiting toxicities, and dose-level safety and activity. Secondary endpoints are objective response rates, duration of response, complete response, progression-free survival, overall survival, PK, and antidrug antibodies. Exploratory biomarkers of OR2805-mediated pharmacodynamic effects and immune stimulation will be explored. The study was opened September 2021 and is enrolling at sites in the United States with planned expansion within the US and to Europe.
