Treatment options for patients with advanced sarcoma remain limited. Promising responses to checkpoint inhibition have been observed, but responses to single-agent PD-1 inhibition are rare. We report on two patients with multiply recurrent myxofibrosarcoma treated with the combination of regionally administered melphalan (via isolated limb infusion) and pembrolizumab. Both patients had recurrent disease after multiple surgical resections and radiation. Analysis of primary tumors demonstrated microsatellite stable tumors with few mutations. After combination treatment, one patient had a significant partial response of 6 months duration, the second patient had a complete response of 2 years duration. Post treatment biopsies demonstrated immune infiltration into the tumor. These promising responses in patients with multiply recurrent myxofibrosarcoma have prompted the development of an investigator-initiated clinical trial to formally study the combination of regional melphalan and pembrolizumab in a systematic fashion (NCT04332874).

4090 Background: Subsets of esophagogastric (EG) cancers harbor genetic abnormalities, including amplification of HER2 or MET, or mutations in PIK3CA, EGFR, or BRAF. These genes encode clients of the molecular chaperone heat-shock protein 90 (HSP90), and inhibition of HSP90 may promote the degradation of these oncogenic signaling proteins. Ganetespib is a novel triazolone heterocyclic inhibitor of HSP90 that is a biologically rational treatment strategy for advanced EG cancers. Methods: This was a multicenter, single-arm Phase 2 trial. Eligibility: Histologically confirmed advanced EG cancer; progression on ≤ 2 lines of systemic therapy; ECOG PS 0-1. Treatment: Ganetespib 200mg/m2IV on Days 1, 8, and 15 of a 28-day cycle. Primary endpoint: overall response rate (ORR). Results: 26/28 patients enrolled received ≥ 1 dose of drug. The characteristics of the 26 patients were: male 77%, median age 64 years old; ECOG PS 0/1 42/58%; median number of prior therapies 2; esophageal/GEJ/gastric 27/42/31%; prior platinum 92%, prior fluoropyrimidine 88%, prior taxane 38%, prior trastuzumab 15%. Median follow-up was 83 days. The most common drug-related adverse events were: diarrhea (77%), fatigue (65%), elevated ALKP (42%), and elevated AST (38%). The most common Grade 3/4 AEs included: leucopenia (12%), fatigue (12%), diarrhea (8%), and elevated ALKP (8%). 14/26 required ≥ 1 dose modification. 22/26 patients completed at least 2 cycles of ganetespib and were evaluable for response. One complete response was seen, and this patient continues on treatment as of cycle 31 (27.5 mos). Molecular characterization of this patient’s tumor revealed a KRAS mutation in codon 12. The ORR was 1/26 (4%). Two of six patients with HER2-positive disease achieved 12% and 19% tumor reduction from baseline, respectively. TTP was 48 days (1.6 mos) and OS was 83 days (2.8 mos). Conclusions: Ganetespib showed manageable toxicity. While the study was terminated early due to insufficient evidence of single agent activity, the durable CR and 2 minor responses suggest that there may be a subset of EG patients who could benefit from this drug. The molecular determinants of response, however, have yet to be fully characterized. Clinical trial information: CT01167114.

Clinical Trial Evidence

e22019 Background: Immune-checkpoint inhibitors (ICI) have dramatically altered the prognosis of metastatic melanoma (MM); however, fifty percent of patients will not respond to ICI. For these patients, the next choice of treatment includes targeted therapy or a clinical trial if eligible. If these treatment choices have already been utilized or are not available to the patient, there may be value in attempting a course of salvage chemotherapy (CTX). Limited clinical trial evidence has demonstrated unexpected efficacy of CTX after prior progression on ipilimumab, offering higher disease control rates than expected from what is seen in first-line chemotherapy. The phenomenon of a “priming” effect of ICI on CTX efficacy has been shown in patients of various solid tumors after progression on anti-PD1/PD-L1 therapy. The purpose of this retrospective analysis is to evaluate the efficacy of salvage CTX after prior ICI therapy for patients with MM. Patients with ocular melanoma were excluded, as this tumor subtype is known to have reduced response to immunotherapy. Methods: By retrospective analysis, patients were included under an IRB approved waiver of consent. We identified patients with MM treated with ICI therapy between Jan, 2011 and July, 2019 who were subsequently treated with salvage CTX as a result of progression of disease (POD). Salvage CTX included dacarbazine, carboplatin, temozolomide, paclitaxel, or a combination. We assessed response rate, duration of response, and time to progression (TTP) from the onset of salvage CTX. Results: A total of 22 patients who satisfied the above criteria were identified. The majority of this population had a course of single agent ICI as well as a course of combination ICI prior to salvage CTX (72.7%, n = 16/22). 13 (59.1%) patients had POD on salvage CTX with a median TTP of 10.9 weeks. 9 (40.9%) patients responded to salvage CTX. 3 (13.6%) patients achieved a complete response, 4 (18.2%) patients achieved a partial response and 2 (9.1%) patients achieved stable disease. Mean durability of response was 53.6 weeks, ranging from 7-194 weeks. Conclusions: ICI “priming” prior to salvage CTX efficacy may improve disease responsiveness to CTX. This sequence of therapy may offer patients another reasonable treatment option. Despite the small sample size of this study, a prospective clinical trial in MM exploring CTX following ICI progression should be considered.

Triple negative breast cancer (TNBC) comprises 12–20 % of all breast cancers and are a heterogeneous group of tumours, both clinically and pathologically. These cancers are characterised by the lack of expression of the hormone receptors oestrogen receptor (OR) and progesterone receptor (PR), combined with the lack of either overexpression or amplification of the human epidermal growth factor receptor-2 (HER2) gene. Conventional cytotoxic chemotherapy and DNA damaging agents continue to be the mainstay of treatment of this disease in the neoadjuvant, adjuvant and metastatic setting. The lack of predictive markers in identifying potential targets for the treatment of TNBC has left a gap in directed therapy in these patients. Platinum agents have seen renewed interest in TNBC based on an increasing body of preclinical and clinical data suggesting encouraging activity. However, comparisons between chemotherapy regimens are mostly retrospective in nature and the best agents or drug combinations for TNBC have not been established in prospective randomised trials. Numerous studies have now shown that TNBC has significantly higher pathological complete response (pCR) rates compared with hormone receptor positive breast cancer when treated with neoadjuvant chemotherapy, and pCR correlates well with better outcomes for these patients. Patients with TNBC account for a larger number of deaths in the setting of metastatic breast cancer. There is no preferred treatment for the first-line metastatic setting. Although individual agents are recommended, given the often aggressive nature of TNBC and the presence of extensive visceral disease, the use of a combination of drugs, rather than a single agent, is often advocated. This review article will outline the pathological diagnosis of TNBC and the treatment options available to these patients in the neoadjuvant, adjuvant and metastatic setting, including an assessment of future directions of treatment.

Background: Despite significant advances in the treatment of multiple myeloma (MM), it remains an incurable malignancy and novel treatments are still desperately needed. Daratumumab, a human IgG1 anti-CD38 monoclonal antibody, is an essential component of several regimens approved for the treatment of both newly diagnosed (NDMM) and relapsed/refectory myeloma (RRMM), however nearly all patients exposed to this agent eventually acquire resistance. Daratumumab (Dara) has known immunomodulatory effects including reducing CD38-expressing immunosuppressive regulatory B- and T-cells, and CD4+ T-helper cells and CD8+ cytotoxic T-cells, leading to increased CD8+:CD4+ and CD8+:Treg ratios. Additionally, CD38 has been shown to be upregulated in solid tumors which acquire resistance to PD-1/PD-L1 blockade. Pembrolizumab (Pembro) a humanized IgG4 monoclonal PD-1 antibody has previously shown limited clinical activity in combination with the immunomodulatory agents lenalidomide or pomalidomide in early phase trials. Although phase 3 trials did not confirm the benefit of Pembro in combination with immunomodulatory drugs, alternative combinations are being explored in clinical trials. Given their overlapping mechanisms, we hypothesize that the combination of Dara and Pembo will lead to increased anti-myeloma activity while maintaining an acceptable safety profile. Methods: We are conducting a phase 2 single arm trial of the combination of Dara and Pembro in RRMM patients previously treated with 3 or more lines of therapy, including an immunomodulatory agent, proteasome inhibitor, and daratumumab (ClinicalTrials.gov NCT04361851). Subjects will receive Dara-Pembro induction for 6 cycles (Q21 days) followed by Dara-Pembro maintenance until relapse or progression. Dara will be dosed at 16 mg/kg administered intravenously at days 1, 8 and 15 for the first 2 induction cycles and 16 mg/kg at days 1 and 15 of each cycle thereafter. Pembro will be dosed at 200 mg administered intravenously on day 1 of each cycle. Response/progression parameters will be assessed using IMWG criteria. Toxicity will be assessed during treatment via NCI CTCAE v. 4.03. Bone marrow aspirates and serial peripheral blood samples will be collected for correlative studies. The primary endpoint is 8-month progression-free survival (PFS) with response compared to the historical control of single agent daratumumab. Classically, single agent Dara has resulted in a median PFS of 4 months in a similar (although Dara naïve) population which corresponds to an 8-month PFS of 25%. For this population of subjects treated with Dara + Pembro, the aim is to improve the 8-month PFS rate to 50%. An optimum Simon 2-stage design will be used to test the hypothesis that the 8-month PFS rate is less than or equal to 25%. Sixteen subjects will be enrolled in the first stage, and if at least 5 of the 16 patients are alive and progression free at 8 months, an additional 17 subjects will be enrolled (total of 33 subjects). If at least 13 of 33 subjects are alive and progression free at 8 months, the null hypothesis will be rejected. Assuming a one-sided α = 0.05 significance level, this sample size will provide 90% power to reject the null hypothesis, assuming the true 8-month PFS rate is 50%. Key secondary endpoints include overall response rate, clinical benefit rate (minimal response or better), CR (complete response) rate, sCR (stringent complete response) rate, time to response (TTR), time to best response (TTBR), duration of response (DOR), progression-free survival (PFS), overall survival (OS) and safety. Safety objectives include dose limiting toxicities and immune-related adverse events (monitored with stopping rules), overall treatment-related adverse events, and a Bayesian-based safety stopping rule for Grade 5 AEs. We also have several translational correlates aimed at identifying molecular subtypes, variants, and neoantigen mutations which may serve as prognostic and predicative immune biomarkers of response to the combination. We also plan to characterize the mechanism(s) of immune exhaustion and T cell dysfunction in RRMM patients. These translational endpoints are aimed to determine patients who would be at highest likelihood to derive benefit from this combination in future studies.

6 Background: Patients (pts) with GC/GEC often present with A/M disease, which has a poor prognosis, with 1-year survival < 30%, and few treatment options. Nivolumab is a fully human anti-PD-1 IgG4 monoclonal antibody with a favorable safety profile and efficacy in melanoma, non–small-cell lung cancer, and renal cell carcinoma. The phase I/II, open-label CheckMate-032 study evaluated nivolumab ± ipilimumab in pts with solid tumors. Here, we report initial results for pts with GEC/GC receiving nivolumab monotherapy. Methods: Pts with A/M histologically confirmed GC/GEC, irrespective of PD-L1 status, were assigned to receive nivolumab alone (3 mg/kg IV Q2W) and treated until disease progression (PD) or intolerable toxicity. The primary endpoint was objective response rate (ORR); other endpoints included safety, progression-free survival, overall survival (OS), and biomarker status. Results: 59 pts were enrolled and treated with single-agent nivolumab. Median age was 60 y (range 29–80), and 83% of pts received ≥ 2 prior regimens. At database lock, 10 pts were on active treatment; 49 pts discontinued (PD, n = 40; unrelated adverse events, n = 4; treatment-related adverse events [TRAEs], n = 2; other, n = 3). Pts received a median of 4 doses (range 1–25). ORR was 12% (n = 7/58; 1 complete response, 6 partial responses); 12 pts (21%) had stable disease. Among responders, median duration of response was 7.1 mo (95% CI, 3.0–13.2). Median OS was 6.8 mo (95% CI, 3.3–12.4); 12-mo OS rate was 38% (95% CI, 23.2–52.7). 39% of tumor samples were PD-L1 positive ( ≥ 1% cutoff). ORRs in pts with PD-L1-positive and -negative tumors were 18% and 12%, respectively. TRAEs occurred in 66% of pts; most were Grade 1/2. Grade 3/4 TRAEs occurred in 14% of pts and included pneumonitis, fatigue, diarrhea, vomiting, hypothyroidism, and increased aspartate and alanine aminotransferase and alkaline phosphatase levels. No treatment-related deaths occurred. Conclusions: Nivolumab monotherapy was well tolerated and demonstrated encouraging antitumor activity in heavily pretreated pts with GC/GEC. Objective responses occurred in pts with PD-L1-positive and -negative tumors. Clinical trial information: NCT01928394.

10508 Background: Outcome for patients with advanced sarcoma is extremely poor and treatment options are limited. Encouragingly, in our phase 1 dose-escalation trial (Ahmed et al, JCO 2015), systemic administration of up to 1x108/m2 autologous HER2-CAR T cells in patient with HER2+ sarcoma was safe. While T cells did not expand, 4/19 evaluable patients are alive 37-61 months post infusion without evidence of disease. The goal of this study was to evaluate if lympohodepleting chemotherapy can safely induce the expansion of HER2-CAR T cells. Methods: In a phase 1 clinical study, NCT00902044, we administered 1x108/m2 autologous HER2-CAR (with a CD28.zeta signaling domain) T cells to patients with refractory/metastatic HER2+ sarcoma after lymphodepletion. Results: Six patients with refractory/metastatic HER2+ sarcoma (4 osteosarcoma, 1 rhabdomyosarcoma, 1 synovial sarcoma) with a median age of 16 (range: 4 to 55) received up to 3 infusions of 1x108 cells/m2 CAR T cells after lymphodepletion with either fludarabine (Flu; n = 3) or Flu and cyclophosphamide (Flu/Cy; n = 3). Flu and Flu/Cy induced lymphopenia with an absolute lymphocyte count (ALC) of < 100/ml at the day of the T-cell infusion. Only Flu/Cy induced neutropenia (absolute neutrophil count [ANC] < 500/ml) for up to 14 days. 4/6 patients developed grade 1-2 cytokine release syndrome (CRS) within 24 hours of CAR T-cell infusion that resolved completely with supportive care within 3 days of onset. T cells expanded in 5/6 patients (median 89-fold (range: 41 to 2,893) with a median peak expansion on day 7 (range: 5 to 28). CAR T cells could be detected by qPCR in 6/6 patients at 6 weeks post infusion. One patient with rhabdomyosarcoma metastatic to the bone marrow had a complete responses (CR), 2 had stable disease (SD), and 3 had progressive disease (PD). Two patients are alive with a median overall survival of 14.2 months. Conclusions: Infusion of autologous HER2-CAR T cells after lymphodepletion is safe, and can be associated with objective clinical benefit in patients with advanced HER2+ sarcoma. These findings warrant further evaluation in a phase 2b study as a single agent or in combination with other approaches. Clinical trial information: NCT00902044.

Reovirus Replication

Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis, with 1 and 5-year survival rates of ~18% and 7% respectively. FOLFIRINOX or gemcitabine in combination with nab-paclitaxel are standard treatment options for metastatic disease. However, both regimens are more toxic than gemcitabine alone. Pelareorep (REOLYSIN®), a proprietary isolate of reovirus Type 3 Dearing, has shown antitumor activity in clinical and preclinical models. In addition to direct cytotoxic effects, pelareorep can trigger antitumor immune responses. Due to the high frequency of RAS mutations in PDAC, we hypothesized that pelareorep would promote selective reovirus replication in pancreatic tumors and enhance the anticancer activity of gemcitabine. Chemotherapy-naïve patients with advanced PDAC were eligible for the study. The primary objective was Clinical Benefit Rate (complete response (CR) + partial response (PR) + stable disease (SD) ≥ 12 weeks) and secondary objectives include overall survival (OS), toxicity, and pharmacodynamics (PD) analysis. The study enrolled 34 patients; results included one partial response, 23 stable disease, and 5 progressive disease. The median OS was 10.2 months, with a 1- and 2-year survival rate of 45% and 24%, respectively. The treatment was well tolerated with manageable nonhematological toxicities. PD analysis revealed reovirus replication within pancreatic tumor and associated apoptosis. Upregulation of immune checkpoint marker PD-L1 suggests future consideration of combining oncolytic virus therapy with anti-PD-L1 inhibitors. We conclude that pelareorep complements single agent gemcitabine in PDAC.

Breast cancer is the main source of death among women. Currently, 77% of women diagnosed with breast cancer are age 50 and older; however, it is projected that approximately 66% of the new cases diagnosed will occur in women younger than 65. Several clinical trials have assessed the wellbeing and adequacy of taxanes along with their tolerability in patients with metastatic cancer (MBC) The overview of these Paclitaxel and Docetaxel, the mechanism of action, pharmacokinetics and pharmacodynamics, dose and administration, adverse effects, clinical potency, and sufferable profiles combination therapies, the pathological complete response of these taxanes are included. The different novel formulations of taxanes are formulated from nanoparticles, polyglutamate, liposomes to improve the wellbeing and adequacy taxanes to reduce their toxicities. Single-agent research located with docetaxel and paclitaxel in metastatic breast most cancers show clinically huge antitumor motion even in the advanced stage, heavily pretreated, safe, as properly as in refractory diseases. This action is likewise clear with taxane-based combination regimens. Serious hematologic and nonhematologic toxicities are incompatible, with different toxicities noted dependent on the portion and weekly regimen selected.  Weekly docetaxel and paclitaxel regimens speak to important helpful treatment options for women suffering from metastatic breast cancer and have entered assessment as a major aspect of adjuvant treatment for this disease Toxicity associated with taxanes chemotherapy are based totally on the dose schedules and weekly regimen selected and the most frequent toxicities related with these marketers include myalgia, peripheral neuropathy, neutropenia, etc Docetaxel retains in tumor cells for longer duration when compared to paclitaxel because of its slow efflux and large amounts of uptake into the cell which explains its more benefits when compared to paclitaxel. Clinical studies conducted so far suggested a more benefit to risk ratio for docetaxel when compared to paclitaxel. This article reviews mainly different actions exhibited by taxanes in the therapy of metastatic breast cancer and others on stages of cancer along with the toxicities associated with these agents.

7535 Background: Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma (iNHL) subtype, yet treatment options in the relapsed/refractory (r/r) setting are limited. Copanlisib is a pan-Class I phosphatidylinositol 3-kinase (PI3K) inhibitor with predominant PI3K-α and PI3K-δ activity. We report results from the FL subset of a large phase II study (n=141) in iNHL patients (pts) (NCT01660451, part B). Methods: A total of 104 pts with indolent FL (grade 1-3a) relapsed/refractory to ≥2 prior lines of treatment were treated with copanlisib (60 mg IV infusion) administered on days 1, 8 and 15 of a 28-day cycle. The primary endpoint was objective tumor response rate (ORR) per independent radiologic review (Cheson et al., JCO 20:579, 2007). Results: Of the 104 pts treated, 62% were refractory; median prior lines 3 (range 2-8), median time from progression 8 wks (range 1-73 wks). 52% were male, 83% white, median age 62 yrs, and 62% ECOG 0. At the time of primary analysis the ORR was 58.7%, comprising 15 pts (14.4%) with complete response (CR) and 46 (44.2%) with partial response. Stable disease was observed in 35 (33.7%) pts and progression of disease as best response in 2 pts. The median duration of response was 370 days (range 0-687), with 43 responders censored at data cut-off. Median duration of treatment was 22 wks (range 1-105); 33 (32%) pts remained on treatment. For all pts, the most common treatment-emergent AEs occurring in >25% of pts included (all grade/grade 3+): diarrhea (34%/5%), reduced neutrophil count (30%/24%), fatigue (30%/2%), and fever (25%/4%). Hyperglycemia (50%/41%) and hypertension (30%/24%) were transient. The incidence of pneumonitis (8%/1.4%), hepatic enzymopathy (AST 28%/1.4%; ALT 23%/1.4%), opportunistic infection (1.4%) and colitis (0.7%) were low. Six deaths were observed, 3 of which were attributed to copanlisib: one lung infection, one respiratory failure, and one thromboembolic event. Conclusions: Copanlisib was highly active as a single agent in heavily pretreated r/r FL pts and resulted in durable responses in the majority of pts. Toxicities were manageable, with a low incidence of severe AEs associated with other PI3K inhibitors, especially hepatic enzymopathy, opportunistic infections, and colitis. Clinical trial information: NCT01660451.
