Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are effective strategies for multiple cancers and may be safe in people living with HIV (PLWH). Camrelizumab is a monoclonal antibody against PD-1 activating T cells against tumor cells. Evidence of camrelizumab's safety and activity in PLWH with urothelial carcinoma (UC) is lacking. Here, findings in a cohort of people living with HIV with advanced or metastatic urothelial carcinoma are presented. METHODS Patients who had locally advanced or metastatic disease after radical surgery were given camrelizumab (200 mg intravenously every 3 weeks). The primary endpoint was objective response per Response Evaluation Criteria in Solid Tumors version 1.1. The second endpoint was adverse events after treatment. RESULTS In total, nine patients were included in this study with a median follow-up of 6.2 months (4.1-20.5). The objective response rate achieved 55%. Tumor response comprised 2 (22%) complete responses and 3 (33%) partial responses. The median of progression-free survival was 6.2 months (95% CI, 9.83-20.63). Only two grade 3 adverse reactions were reported (no toxic deaths or immune-related deaths). CONCLUSION Camrelizumab showed potent antitumor activity and acceptable safety in PLWH with advanced or metastatic urothelial carcinoma.

Abstract
Cancer immunotherapy, largely represented by immune checkpoint inhibitors (ICI), has led to substantial changes in preclinical cancer research and clinical oncology practice over the past decade. However, the efficacy and toxicity profiles of ICIs remain highly variable among patients, with only a fraction achieving a significant benefit. New combination therapeutic strategies are being investigated, and the search for novel predictive biomarkers is ongoing, mainly focusing on tumor- and host-intrinsic components. Less attention has been directed to all the external, potentially modifiable factors that compose the exposome, including diet and lifestyle, infections, vaccinations, and concomitant medications, that could affect the immune system response and its activity against cancer cells. We hereby provide a review of the available clinical evidence elucidating the impact of host-extrinsic factors on ICI response and toxicity.

Abstract
BACKGROUND People living with HIV (PLWH) have a worse prognosis than the general population. Locally advanced or metastatic bladder cancer (BCa) in PLWH has gradually been increasing in recent years. Immune checkpoint inhibitors can improve antitumor activity in the general population, but relevant data in PLWH are unknown. We thus evaluated the efficacy and safety of tislelizumab in PLWH with locally advanced or metastatic BCa. METHODS This retrospective study included 24 patients with locally advanced or metastatic BCa, both HIV positive or negative who underwent tislelizumab treatment (200 mg i.v. every 3 weeks, Q3W) from the multi-centers between December 2019 and March 2022. Demographic details, clinical data, and cancer status were collected. The overall survival (OS), progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), clinical benefit rate (CBR), and treatment-related adverse events (TRAEs) were recorded and evaluated. RESULTS A total of 24 individuals were chosen for this study, 10 had HIV and the other 14 did not. The median OS in the HIV-negative group was 62.3 (95% CI, 52.6 to 72.2) was no longer than that of the PLWH group 41.9 (95% CI, 32.9 to 51.0) weeks (HR .7, [95% CI, .17 to 3.30], P = .70). Furthermore, the median PFS in the HIV-negative group was 50.0 (95% CI, 36.2 to 63.9) was also no longer than that of the PLWH group 35.9 (95% CI, 25.5 to 46.3) (HR, 1.34, [95% CI, .38 to 4.69], P = .63). Of 24 patients, treatment-related adverse events, grade 3 or 4 occurred in 2 in the PLWH group and 3 in the HIV-negative group. CONCLUSION This retrospective multi-center study suggested that tislelizumab may provide encouraging antitumor activity and could be generally well tolerated. In this retrospective analysis of patients with locally advanced or metastatic BCa, it seems that PLWH may have similar overall and progression-free survival compared to HIV-negative cases.

Abstract
Patient-centered trials are pivotal to advancing the oncology field efficiently. However, in recent years, there has been a shift away from patient-centered approaches. In this commentary, we describe common non-patient-centric practices of contemporary trials, discuss their implications, and propose potential solutions to relocate patients to the center of trials where they belong.

Abstract
Cancer clinical trial eligibility criteria may create patient populations studied in trials that do not reflect the patient populations treated in the real-world setting. Follicular lymphoma (FL) is an indolent lymphoma with heterogeneous presentations across a broad range of individuals, resulting in many acceptable management strategies. We evaluated how first-line clinical trial eligibility criteria impacted the demographic makeup and outcomes of FL patients for whom systemic therapy might be considered. We compared the characteristics of 196 FL patients from a single institution to eligibility criteria from 10 first-line FL trials on ClinicalTrials.gov. Next, we tabulated eligibility criteria from 24 first-line FL protocols and evaluated their impact on 1198 FL patients with stages II-IV disease from the prospective Molecular Epidemiology Resource (MER) and Lymphoma Epidemiology of Outcomes (LEO) cohort studies. We found that 39.8% and 52.7% of FL patients might be excluded from clinical trials based on eligibility criteria derived from ClinicalTrials.gov and protocol documents, respectively. Patients excluded due to renal function, prior malignancy, and self-reported serious health conditions tended to be older. Expanding stage requirement from III-IV to II-IV and platelet requirement from ≥150 000 to ≥75 000 increased population size by 21% and 8%, respectively, in MER and by 16% and 13%, respectively, in LEO, without impacting patient demographics or outcomes. These data suggest that management of older individuals with FL may not be fully informed by recent clinical trials. Moreover, liberalizing stage and platelet criteria might expand the eligible population and allow for quicker trial accrual without impacting outcomes.

Abstract
Background Targeting immune checkpoints for HIV treatment potentially provides a double benefit resulting from the ability to restore viral-specific CD8+ T-cell functions and enhance HIV production from reservoir cells. Despite promising pre-clinical data, PD-1 blockade alone in HIV-1-infected patients with advanced cancer has shown limited benefits in controlling HIV, suggesting the need for additional targets beyond PD-1. CD39 and PD-1 are highly co-expressed on CD8+ T cells in HIV-1 infection. However, the characteristics of CD39 and PD-1 dual-positive CD8+ T-cell subsets in chronic HIV-1 infection remain poorly understood. Methods This study enrolled 72 HIV-1-infected patients, including 40 treatment naïve and 32 ART patients. A total of 11 healthy individuals were included as controls. Different subsets of CD8+ T cells defined by CD39 and/or PD-1 expression were studied by flow cytometry. The relationships between the frequencies of the different subsets and parameters indicating HIV-1 disease progression were analyzed. Functional (i.e., cytokine secretion, viral inhibition) assays were performed to evaluate the impact of the blockade of adenosine and/or PD-1 signaling on CD8+ T cells. Results The proportions of PD-1+, CD39+, and PD-1+CD39+ CD8+ T cells were significantly increased in treatment naïve patients but were partially lowered in patients on antiretroviral therapy. In treatment naïve patients, the proportions of PD-1+CD39+ CD8+ T cells were negatively correlated with CD4+ T-cell counts and the CD4/CD8 ratio, and were positively correlated with viral load. CD39+CD8+ T cells expressed high levels of the A2A adenosine receptor and were more sensitive to 2-chloroadenosine-mediated functional inhibition than their CD39- counterparts. In vitro, a combination of blocking CD39/adenosine and PD-1 signaling showed a synergic effect in restoring CD8+ T-cell function, as evidenced by enhanced abilities to secrete functional cytokines and to kill autologous reservoir cells. Conclusion In patients with chronic HIV-1 infection there are increased frequencies of PD-1+, CD39+, and PD-1+CD39+ CD8+ T cells. In treatment naïve patients, the frequencies of PD-1+CD39+ CD8+ T cells are negatively correlated with CD4+ T-cell counts and the CD4/CD8 ratio and positively correlated with viral load. Combined blockade of CD39/adenosine and PD-1 signaling in vitro may exert a synergistic effect in restoring CD8+ T-cell function in HIV-1-infected patients.

Abstract
IMPORTANCE Anti-programmed death 1 and anti-programmed death ligand 1 (anti-PD1/PDL1) immune checkpoint blockade (ICB) constitutes the therapeutic backbone for multiple malignant neoplasms. People living with HIV (PLWH) have routinely been excluded from ICB clinical trials, thus inhibiting broad implementation of ICB to PLWH with cancer. OBJECTIVE To evaluate trends in the inclusion of PLWH in ICB cancer clinical trials that have occurred in association with ongoing efforts by the Cancer Therapy Evaluation Program (CTEP), National Cancer Institute, to promote inclusion of PLWH. DESIGN, SETTING, AND PARTICIPANTS This quality improvement study of ICB letters of intent (LOIs) included anti-PD1/PDL1 agents (nivolumab, pembrolizumab, atezolizumab, and durvalumab) submitted to CTEP that proceeded to approved protocols between January 2014 to May 2019. The setting was ICB clinical trial development and inclusion of underrepresented populations, specifically PLWH. All 97 submitted cancer clinical trial LOIs that included the aforementioned ICB agents were eligible for inclusion. Ten proposals were excluded, of which 3 were designed specifically for PLWH and 7 were LOIs that did not advance to approved protocols within the study period. Statistical analysis was performed from April to September 2020. EXPOSURES CTEP advocacy included the requirement for justification of exclusion of PLWH and formal discussion of inclusion criteria during conference calls between CTEP and trial investigators. MAIN OUTCOMES AND MEASURES The frequency of inclusion of PLWH in initially submitted LOIs was compared with final approved protocols using descriptive statistics. The probability of inclusion of PLWH in submitted LOIs and approved protocols over time was assessed using logistic regression. RESULTS Eighty-seven studies were included, of which 68 (78%) were pilot, phase 1, phase 1/2, or phase 2 studies and 19 (22%) were phase 2/3 or phase 3 studies. Thirty-nine studies (45%) included nivolumab, 23 (26%) included pembrolizumab, 19 (22%) included atezolizumab, and 6 (7%) included durvalumab. At initial LOI stage, 14 of 87 (16%) included PLWH. Following CTEP advocacy efforts, 61 of 87 protocols (70%) included PLWH. Of 36 LOIs to initially exclude PLWH, 24 (67%) included PLWH in final protocols. Among the 25 protocols to exclude PLWH, 21 (84%) were earlier phase studies (pilot to phase 2) and 4 (16%) were later phase studies (phase 2/3 to phase 3). Only 13 of 25 protocols (52%) provided justification for exclusion of PLWH, with safety being the most frequently cited concern (9 of 13 studies). The inclusion of PLWH on submitted LOIs increased over time (odds ratio, 3.38; 95% CI, 1.14-3.91), whereas inclusion on final protocols did not increase over time (odds ratio, 1.80; 95% CI, 0.81-1.59). CONCLUSIONS AND RELEVANCE This study identified encouraging trends in the inclusion of PLWH in anti-PD1/PDL1 cancer trials that occurred in the period following the initiation of CTEP advocacy. Work is needed to examine what impact this will have on enrollment of PLWH in such trials. Similar advocacy may help to promote inclusion of other underrepresented populations in cancer clinical trials, including those with organ dysfunction and chronic infections.

Abstract
The present review summarizes up-to-date evidence addressing the frequently discussed clinical controversies regarding the use of immune checkpoint inhibitors (ICIs) in cancer patients with viral infections, including AIDS, hepatitis B and C, progressive multifocal leukoencephalopathy, influenza, and COVID-19. In detail, we provide available information on (1) safety regarding the risk of new infections, (2) effects on the outcome of pre-existing infections, (3) whether immunosuppressive drugs used to treat ICI-related adverse events affect the risk of infection or virulence of pre-existing infections, (4) whether the use of vaccines in ICI-treated patients is considered safe, and (5) whether there are beneficial effects of ICIs that even qualify them as a therapeutic approach for these viral infections.

Abstract
Immune activation is the hallmark of HIV infection and plays a role in the pathogenesis of the disease. In the context of suppressed HIV RNA replication by combination antiretroviral therapy (cART), there remains immune activation which is associated to the HIV reservoirs. Persistent virus contributes to a sustained inflammatory environment promoting accumulation of "activated/exhausted" T cells with diminished effector function. These T cells show increased expression of immunomodulatory receptors including Programmed cell death protein (PD1), Cytotoxic T Lymphocyte Associated Protein 4 (CTLA4), Lymphocyte activation gene 3 (LAG3), T cell immunoglobulin and ITIM domain (TIGIT), T cell immunoglobulin and mucin domain containing 3 (TIM3) among others. More importantly, recent reports had demonstrated that, HIV infected T cells express checkpoint receptors, contributing to their survival and promoting maintenance of the viral reservoir. Therapeutic strategies are focused on viral reservoir elimination and/or those to achieve sustained cART-free virologic remission. In this review, we will discuss the immunological basis and the latest advances of the use of checkpoint inhibitors to treat HIV infection.
