Cardiovascular preventive strategies are guided by risk scores with unknown validity in cancer cohorts. This study aimed to evaluate the predictive performance of 7 established cardiovascular risk scores in cancer survivors from the UK Biobank. The predictive performance of QRISK3, Systematic Coronary Risk Evaluation 2 (SCORE2)/Systematic Coronary Risk Evaluation for Older Persons (SCORE-OP), Framingham Risk Score, Pooled Cohort equations to Prevent Heart Failure (PCP-HF), CHARGE-AF, QStroke, and CHA2DS2-VASc was calculated in participants with and without a history of cancer. Participants were propensity matched on age, sex, deprivation, health behaviors, family history, and metabolic conditions. Analyses were stratified into any cancer, breast, lung, prostate, brain/central nervous system, hematologic malignancies, Hodgkin lymphoma, and non-Hodgkin lymphoma. Incident cardiovascular events were tracked through health record linkage over 10 years of follow-up. The area under the receiver operating curve, balanced accuracy, and sensitivity were reported. The analysis included 31,534 cancer survivors and 126,136 covariate-matched controls. Risk score distributions were near identical in cases and controls. Participants with any cancer had a significantly higher incidence of all cardiovascular outcomes than matched controls. Performance metrics were significantly worse for all risk scores in cancer cases than in matched controls. The most notable differences were among participants with a history of hematologic malignancies who had significantly higher outcome rates and poorer risk score performance than their matched controls. The performance of risk scores for predicting stroke in participants with brain/central nervous system cancer was very poor, with predictive accuracy more than 30% lower than noncancer controls. Existing cardiovascular risk scores have significantly worse predictive accuracy in cancer survivors compared with noncancer comparators, leading to an underestimation of risk in this cohort.

TPS5630 Background: Platinum-resistant ovarian cancer (PROC) portends a poor prognosis and, although treatments are available, response rates are low. Previous studies have demonstrated that DNA topoisomerase I (TOP1) inhibitors exhibit clinical activity in PROC. Irinotecan also has a 15-25% response rate in some studies of platinum-resistant epithelial ovarian cancer but does not have FDA approval for this indication. Additional studies in preclinical models suggest that TOP1 poisons are more active if administered at low doses on prolonged schedules. PLX038 is a long-acting prodrug of the potent TOP1 inhibitor SN-38. In PLX038, SN-38 is covalently conjugated to circulating polyethylene glycol and is slowly released at a constant rate to provide the active agent with a long half-life, a low C max and very high exposure – important facets for optimal safety and efficacy of this drug. Further, in preclinical studies the nanoparticle prodrug accumulates and is retained in tumors, where it slowly releases the SN-38. Methods: This single arm, phase 2 clinical trial is open at Mayo Clinic in Rochester, MN. The primary endpoint is overall response rate and secondary endpoints include progression-free survival and assessment of tolerability of PLX038. Correlative goals include i) measurement of TOP1-DNA covalent complexes in tumor biopsies and circulating tumor cells to assess successful target engagement; ii) assessment of homologous recombination status and SLFN11 expression for correlation with tumor response rate; and iii) pharmacokinetics of SN-38 and SN-38G as well as their association with GI toxicity. Assessment of gut microbiota and association with GI toxicity profile are also being investigated. Eligible patients include women with platinum resistant high grade serous ovarian, primary peritoneal, and fallopian tube cancer who have received fewer than two prior chemotherapy regimens in the platinum-resistant setting. All patients must have an ECOG performance status of 0, 1, or 2 and adequate bone marrow, renal, and hepatic function. As of January 31, 2024, 12 of planned 37 patients have enrolled. Clinical trial information: NCT05465941 .

Journal: Journal of Clinical Oncology (2024)

TPS5623 Background: The association between cervical cancer and human papillomavirus (HPV) is well understood, with nearly all cervical cancer known to be caused by high risk HPV infection. HPV16 and HPV18 are the most common high-risk HPV types and are responsible for about 70% of cervical cancer cases. Recurrent or metastatic cervical cancer is currently treated with pembrolizumab alone or in combination with chemotherapy, however t there remains a significant need for treatments for patients that recur or do not respond at all to pembrolizumab treatment. PRGN-2009 is a gorilla adenovirus-based immunotherapy targeting cancers caused by HPV16 or HPV18. PRGN-2009 includes a novel HPV antigen design to induce HPV16/18-specific T cell immune responses against cancer cells. The rationale for combining the PRGN-2009 with immune checkpoint inhibitor is based on preclinical and clinical data demonstrating that combination of cancer vaccines and immune checkpoint inhibitors can trigger intensified immunogenicity leading to increased antitumor efficacy compared to either treatment alone. PRGN-2009 has been characterized in both in vitroand in vivostudies to support the scientific rationale and the safety of PRGN-2009 has been demonstrated in evaluated in initial Phase 1/2 studies in patients with HPV+ malignancies. Methods: This is a randomized, Phase 2 study to evaluate efficacy and safety of PRGN-2009 in combination with pembrolizumab compared to pembrolizumab alone in patients with recurrent or metastatic cervical cancer. Key inclusion criteria include recurrent or metastatic cervical cancer (histologically or cytologically confirmed) resistant to pembrolizumab. Subjects will be randomized 1:1 to Cohort 1: Combination of PRGN-2009, 5 x 10 11 PU (Day 0, Day 21 and Day 42, then q6w), plus pembrolizumab, 400mg q6w, or to Cohort 2: pembrolizumab alone (400 mg q6w). Subjects randomized to Cohort 2 (pembrolizumab monotherapy) and who have confirmed disease progression (per RECIST 1.1) after at least one cycle of pembrolizumab and have had no Grade ≥ 3 adverse events related to treatment will be offered the option to crossover to Cohort 1 (PRGN-2009 plus pembrolizumab). All subjects will be evaluated for safety and efficacy of PRGN-2009 in combination with pembrolizumab, and for biological correlative assays. The primary endpoint is objective response rate (ORR) following treatment with PRGN-2009 in combination with pembrolizumab or pembrolizumab monotherapy, and will be tested using Fleming’s two-stage design and the stopping boundaries for futility and efficacy applied. The study is currently recruiting patients with recurrent or metastatic cervical cancer (NCT06157151). Clinical trial information: NCT06157151 .
A three-arm randomized phase II study of dostarlimab alone or with bevacizumab versus nonplatinum chemotherapy in recurrent gynecological clear cell carcinoma: DOVE (APGOT-OV7/ENGOT-ov80 study).

Journal: Journal of Clinical Oncology (2024)

TPS5627 Background: Recurrent gynecological clear cell carcinoma (rGCCC) is known for low objective response rates to chemotherapy. Prior preclinical and clinical data suggests potential synergy of immune checkpoint inhibitor adding bev in rGCCC. Dostarlimab, a humanized monoclonal antibody targeting PD-1, combined with the anti-angiogenic bevacizumab, presents a novel therapeutic approach. The aim of the present study is to investigate the efficacy of dostarlimab +/- bevacizumab in rGCCC. Methods: DOVE is a global, multicenter, international, open-label, randomized phase 2 study of dostarlimab +/- bevacizumab with standard chemotherapy in patients with rGCCC. It enrolls 198 patients with rGCCC, assigning them to one of three groups in a 1:1:1 ratio: Group A (dostarlimab monotherapy), Group B (dostarlimab + bevacizumab), Group C: investigator’s choice chemotherapy. Patients with PD on Group A or Group C were allowed to crossover to Group B. Stratification factors are prior bevacizumab use, prior lines of therapy (1 vs. &gt;1), and primary site (ovarian vs. non-ovarian). Key inclusion criteria are histologically proven confirmed recurrent or persistent clear cell carcinoma of the ovary, endometrium, cervix, vagina and vulva, up to 5 prior lines of therapies, disease progression within 12 months after platinum-based chemotherapy, and measurable disease. Key exclusion criteria are prior treatment with an anti PD-1, anti PD-L1, or anti PD-L2 agent. The primary endpoint is progression-free survival by investigator. The secondary endpoints include ORR, DCB, DCR, PFS2, OS, and toxicity. Exploratory objectives include immune biomarker. The study, commencing in Jan 2024, is registered with Clinicaltrials.gov (NCT06023862). Clinical trial information: NCT06023862 .
Open-label, prospective phase 2 study to evaluate the efficacy and safety of camrelizumab combined with etoposide and cisplatin as neoadjuvant therapy in patients with neuroendocrine carcinoma of the cervix.
Authors: Haixin He, Haijuan Yu, Cuibo Lin, Yongwei Lu, Jian Chen
Journal: Journal of Clinical Oncology (2024)

TPS5624 Background: Camrelizumab, a humanized monoclonal antibody, specifically targets PD-1 to inhibit its interaction with PD-L1, thereby reactivating the T cell immune response against tumors. The NACI study demonstrated that, in the treatment of locally advanced cervical cancer, the combination of camrelizumab and neoadjuvant chemotherapy achieved an overall response rate (ORR) of 100%. Specifically, complete remission was observed in 4 patients (8.33%), while 44 patients (91.67%) experienced partial remission. This regimen significantly outperformed traditional treatments in efficacy, with manageable toxicity levels. Neuroendocrine carcinoma of the cervix (NECC) is a highly rare and aggressive malignancy characterized by its distinctive biological behavior, propensity for early lymph node and hematogenous metastasis, and limited effective treatment options, leading to a dismal prognosis. Although PD-1 inhibitors have shown promise in some NECC case reports, there is a notable absence of comprehensive, prospective clinical trials to substantiate their effectiveness. This study aims to assess the efficacy and safety of neoadjuvant chemo-immunotherapy in patients with NECC. Methods: This open-label, single-arm, prospective phase II study evaluates the antitumor efficacy and safety of camrelizumab in combination with etoposide and cisplatin in roughly 30 patients with NECC. Eligible participants are aged 18-75, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0–1, and histologically confirmed NECC, specifically targeting small cell and large cell neuroendocrine cervical carcinoma but excluding atypical and typical carcinoid tumors. Inclusion criteria stipulate that if NECC is present alongside other tumor types, the neuroendocrine carcinoma component must account for more than 60% of the tumor mass. The treatment protocol involves neoadjuvant chemo-immunotherapy, comprising two to three cycles of camrelizumab (200 mg, IV, day 1), cisplatin (75 mg/m², IV, day 1), and etoposide (100 mg/m², IV, days 1-3) administered every three weeks. Following this, patients achieving complete or partial response will proceed to radical surgery and adjuvant therapy, while those with stable or progressive disease, or considered unsuitable for surgery by gynecological oncologists, will transfer to concurrent chemoradiotherapy. The primary objective is to ascertain the objective response rate as per the Response Evaluation Criteria in Solid Tumors version 1.1. Secondary objectives include disease control rate, progression-free survival, overall survival, and evaluations of safety and tolerability. The study began on December 28, 2023, with ongoing enrollment. Clinical trial information: NCT05910177 .

TPS5622 Background: In advanced/recurrent cervical cancer, immune checkpoint inhibitors have emerged as an attractive alternative and have demonstrated impressive therapeutic responses. As a result, the combination of pembrolizumab with platinum/taxane chemotherapy with or without bevacizumab received FDA approval for first-line systemic therapy in persistent, recurrent, or metastatic PD-L1+ cervical cancer. However, this regimen demonstrates the greatest impact on survival when all four drugs are utilized and are not without the potential for significant toxicity. CheckMate-358 utilized two dosing regimens of ipilimumab and nivolumab in advanced/recurrent cervical cancer. In the preliminary results, the utilization of either dosing regimen resulted in remarkable, durable responses in chemo-naïve patients with the median overall survival not reached. Given the potential benefit of CTLA-4/PD-1 blockade in the upfront setting, we propose a phase II trial examining the strategy of induction immunotherapy with lorigerlimab (bispecific antibody targeting CTLA-4 and PD-1) in chemo-naïve cervical cancer patients not amenable to curative treatment. Methods: The study is a phase II, multi-site clinical trial conducted at MD Anderson Cancer Center and Lyndon B. Johnson General Hospital. In the induction phase, patients will receive intravenous (IV) lorigerlimab at the recommended phase II dose (6 mg/kg) for three 21-day cycles with a repeat CT scan performed at week 9 of treatment. Tumor response (by RECIST v1.1) to induction immunotherapy will be used to triage patients to either continuation of lorigerlimab (if at least stable disease) or standard of care treatment (if disease progression) in the triaged treatment phase. Lorigerlimab will be continued until progression or intolerable toxicity, for a maximum of 35 cycles. At any time point, all patients at first disease progression will subsequently receive physician’s choice standard of care systemic therapy with carboplatin/paclitaxel +/- pembrolizumab +/- bevacizumab and will be followed for survival. The primary objective is to estimate disease control rate. Secondary objectives are to determine objective response rate, duration of response, overall survival, progression-free survival, and safety (by CTCAE v5.0). Key eligibility criteria include 1) recurrent, metastatic, or persistent cervical cancer 2) squamous cell carcinoma, adenosquamous, or adenocarcinoma histologic subtype 3) not amenable to curative surgery or radiation. The trial is open with 14 of planned 40 patients enrolled at the time of submission. Clinical trial information: NCT05475171 .

Journal: Journal of Clinical Oncology (2024)

TPS5629 Background: Recombinant interleukins (rIL) have had limited clinical success due to inefficient tumor targeting and short PK, requiring frequent dosing that leads to aberrant immunostimulation and toxicity. IL-12 potently activates T and NK cells to produce IFNγ and kill tumor cells, yet dosing strategies have failed to provide adequate therapeutic benefit in humans. We developed a novel platform that delivers immunomodulator(s) linked to a fully-human albumin binding (F H AB) domain (Cini, Front Immunol 2023). Single-chain native IL-12 genetically linked to the F H AB provides enhanced tumor targeting and retention through albumin binding to over-expressed FcRn, GP60, and SPARC in the tumor microenvironment (TME), with an improved PK profile, a dose-sparing effect that decreases the toxicity risk, and a broader therapeutic index. Tumor growth inhibition in an immunologically ‘cold’ B16-F10 mouse melanoma model showed the efficacy of IL12-F H AB compared with rIL-12, resulting in significant increases in activated NK, NKT, Th1, and cytotoxic CD8 T cells. SON-1010 is being studied clinically as monotherapy (study SB101) in advanced solid tumors and in healthy volunteers (study SB102) (Chawla, AACR 2023). Atezolizumab (Tecentriq), an anti-PD-L1 immune checkpoint inhibitor (ICI), has shown preliminary clinical activity in Phase 1 studies of patients with platinum-resistant ovarian cancer (PROC) (Liu, Gyn Onc 2019; Moroney, Clin Canc Res 2020). SON-1010 may ‘warm up’ the TME to improve ICI effectiveness in these immunologically-active tumors that have high levels of SPARC. Methods: Study SB221 is a Phase 1b/2a multicenter, dose-escalation and proof-of-concept study to assess the safety, tolerability, PK, PD, and efficacy of SON-1010 administered SC, either alone or in combination with a fixed dose of atezolizumab given IV (NCT05756907). The study is designed in Part 1 to rapidly establish the maximum tolerated dose (MTD) of the combination in patients with advanced solid tumors with up to 5 dose-escalation groups and to expand the dataset using patients with PROC to establish the Recommended Phase 2 Dose (RP2D). Once the likelihood of efficacy is shown in a Simon 2-stage design, this will be followed in Part 2 by an assessment of the potential for improved efficacy of the combination in patients with PROC over SON-1010 alone or the standard of care (SOC). The first dose-escalation cohorts have been enrolled and additional sites are being added to help with recruitment of patients with PROC. Combination of SON-1010 with an ICI offers a unique opportunity to use this extended PK version of IL-12 to augment the potential for tumor control in PROC, which represents a significant unmet medical need.

Importance Micromobility, the use of small vehicles (primarily scooters and bicycles), has become a standard transportation method in the US. Despite broad adoption of electric micromobility vehicles, there is a paucity of data regarding the injury profiles of these vehicles, particularly in the US. Objective To characterize micromobility injury trends in the US, identify demographic characteristic differences in users of electric and conventional vehicles, and identify factors associated with hospitalization. Design, Setting, and Participants This cross-sectional study queried the National Electronic Injury Surveillance System, a comprehensive database that collates injury data associated with consumer products from emergency departments across the US to provide national estimates, from calendar year 2017 to 2022. Data on micromobility vehicle injuries (bicycles, scooters, electric bicycles [e-bicycles], and electric scooters [e-scooters]) were obtained. Main Outcomes and Measures Trends in injury and hospitalization counts, injury characteristics, and factors associated with hospitalization. Results From 2017 to 2022, the US recorded 2 499 843 bicycle (95% CI, 1 948 539-3 051 147), 304 783 scooter (95% CI, 232 466-377 099), 45 586 e-bicycle (95% CI, 17 684-73 488), and 189 517 e-scooter (95% CI, 126 101-252 932) injuries. The median age of the riders was 28 (IQR, 12-51) years; 72% were male, 1.5% Asian, 13% Black, 12% Hispanic, and 49% White. Annual e-bicycle and e-scooter injuries increased from 751 (95% CI, 0-1586) to 23 493 (95% CI, 11 043-35 944) and injuries increased from 8566 (95% CI, 5522-11 611) to 56 847 (95% CI, 39 673-74 022). Compared with conventional vehicles, electric vehicle accidents involved older individuals (median age, 31 vs 27 years; P &amp;amp;lt; .001) and a higher proportion of Black riders (25% vs 12%; P &amp;amp;lt; .001). Helmet use was less in electric vehicle incidents compared with conventional vehicles (43% vs 52%; P = .02), and injuries were more common in urban settings (83% vs 71%; P = .008). Age-adjusted odds of hospitalization among all Black individuals compared with White individuals was 0.76 (95% CI, 0.59-0.98; P = .04). Conclusions and Relevance In this cross-sectional study of micromobility vehicles, an increased number of injuries and hospitalizations was observed with electric vehicles compared with conventional vehicles from 2017 to 2022. These findings suggest the need for change in educational policies, infrastructure, and law to recenter on safety with the use of micromobility vehicles.
