Few effective second-line treatments exist for women with recurrent or metastatic cervical cancer. Accordingly, we aimed to evaluate the efficacy and safety of tisotumab vedotin, a tissue ...factor-directed antibody–drug conjugate, in this patient population.
This multicentre, open-label, single-arm, phase 2 study was done across 35 academic centres, hospitals, and community practices in Europe and the USA. The study included patients aged 18 years or older who had recurrent or metastatic squamous cell, adenocarcinoma, or adenosquamous cervical cancer; disease progression on or after doublet chemotherapy with bevacizumab (if eligible by local standards); who had received two or fewer previous systemic regimens for recurrent or metastatic disease; had measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST; version 1.1); and had an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients received 2·0 mg/kg (up to a maximum of 200 mg) tisotumab vedotin intravenously once every 3 weeks until disease progression (determined by the independent review committee) or unacceptable toxicity. The primary endpoint was confirmed objective response rate based on RECIST (version 1.1), as assessed by the independent review committee. Activity and safety analyses were done in patients who received at least one dose of the drug. This study is ongoing with recruitment completed and is registered with ClinicalTrials.gov, NCT03438396.
102 patients were enrolled between June 12, 2018, and April 11, 2019; 101 patients received at least one dose of tisotumab vedotin. Median follow-up at the time of analysis was 10·0 months (IQR 6·1–13·0). The confirmed objective response rate was 24% (95% CI 16–33), with seven (7%) complete responses and 17 (17%) partial responses. The most common treatment-related adverse events included alopecia (38 38% of 101 patients), epistaxis (30 30%), nausea (27 27%), conjunctivitis (26 26%), fatigue (26 26%), and dry eye (23 23%). Grade 3 or worse treatment-related adverse events were reported in 28 (28%) patients and included neutropenia (three 3% patients), fatigue (two 2%), ulcerative keratitis (two 2%), and peripheral neuropathies (two 2% each with sensory, motor, sensorimotor, and neuropathy peripheral). Serious treatment-related adverse events occurred in 13 (13%) patients, the most common of which included peripheral sensorimotor neuropathy (two 2% patients) and pyrexia (two 2%). One death due to septic shock was considered by the investigator to be related to therapy. Three deaths unrelated to treatment were reported, including one case of ileus and two unknown causes.
Tisotumab vedotin showed clinically meaningful and durable antitumour activity with a manageable and tolerable safety profile in women with previously treated recurrent or metastatic cervical cancer. Given the poor prognosis for this patient population and the low activity of current therapies in this setting, tisotumab vedotin, if approved, would represent a new treatment for women with recurrent or metastatic cervical cancer.

We report the case of a 68-year-old male who was hospitalized for suspicion of endoleak and thrombosis of an aortic endoprosthesis, arising after multiple endovascular interventions during the last ...few months. During the intervention, amass was discovered, and biopsies were made. The anatomopathology results were in favor of an epithelioid angiosarcoma with atypical expression of CD31 and ERG- and no amplification of c-MYC. The main objective of this review is to highlight the difficulty of differential diagnosis, but also to evaluate overall survival according to treatments.
We performed a large review of the literature using PubMed for reports concerning angiosarcoma arising from Dacron grafts from 1981 to 2019. Articles presenting potentially relevant studies were read and analyzed.
In our review, most of the patients were male (10 cases over 11 described), with amedian age of 63 years old (50-84 years old, 11 cases described). The overall interval time for the diagnosis after the endoprosthesis placement was 7.8 years (from 3.5 years to 17 years, 10 cases with the description) and the overall survival was 5 months (from 0 to 10 months, the only patient alive is not included, and only 8 cases had the description).
In most of the reviewed cases, there was no information concerning immunohistochemistry. Biopsies remain the standard for the diagnosis with immunochemistry and molecular test to avoid amisdiagnosis. Epithelioid angiosarcomas derived from Dacron grafts are a rare entity, which are difficult to diagnose because of the paucity of cases. Prognosis is poor, even if surgical option is possible.
To assess the efficacy and toxicity of the addition of estramustine to docetaxel (D) for the treatment of metastatic hormone-refractory prostate cancer.
One hundred fifty patients were randomly ...assigned to D alone (35 mg/m(2) on days 2 and 9, every 3 weeks) or D in combination with estramustine (D/E; 280 mg orally three times a day on days 1 to 5 and 8 to 12, every 3 weeks). All patients received prednisone (10 mg/d). The primary end point was prostate-specific antigen (PSA) response rate, which was defined as a decrease in PSA > or = 50% from baseline. The study was powered to test the hypothesis that D/E would improve the PSA response rate by 25%.
The PSA response rate was not statistically different between the two groups. PSA of less than 4 ng/mL occurred in 29 (41%) of 71 patients receiving D/E and in 17 (25%) of 69 patients receiving D (P = .05). No significant differences were found for median time to PSA progression (D/E, 6.9 months; D, 7.3 months) or median overall survival time (D/E, 19.3 months; D, 21 months). More patients had at least one grade 3 or 4 toxicity with D/E (45%) compared with D (21%; P = .005), mainly as a result of grade 3 or 4 GI toxicity (P = .05). Serious adverse events were more frequent with D/E (n = 20) than with D (n = 9; P = .04).
The addition of estramustine to weekly D does not provide any clinically relevant advantage. Both regimens are well tolerated, although the toxicity profile favors D without estramustine.
Abstract
Background: The association of immune checkpoints inhibitors (ICI) and dose dense chemotherapy is a promising combination in a neoadjuvant setting for triple negative breast cancers (TNBC). ...However, response rates vary from one study to another and timing, best chemotherapy partner and efficacy in breast cancer subtypes considered as less immunogenic, like luminal B tumors, should be further investigated. The B-immune study evaluates a neoadjuvant treatment with paclitaxel followed by a short combination of an anti-PD-L1 antibody with anthracyclines for TNBC and luminal B breast cancers (BC). Method: B-immune (NCT03356860), a multicentric phase Ib/II prospective trial, includes patients with stage I to III luminal B or TNBC treated with paclitaxel 80mg/m2 weekly from week 1 to 12 followed by 4 cycles of epirubicine 90mg/m2 and cyclophosphamide 600 mg/m2 (EC) Q2W in a neoadjuvant setting. The phase Ib evaluated a single infusion of durvalumab (anti-PD-L1) combined with the 3rd cycle of EC. The phase II, in progress, evaluates 2 infusions of durvalumab with the 1st and 3rd cycle of EC respectively. Surgery is planned 3 weeks after the last preoperative treatment. Primary objectives are safety and efficacy based on pathological complete response (pCR) rate. Considering a 2-stage Simon design, 22 TNBC patients are needed in the phase II to detect a pCR rate increase from 30% to 60% and 24 luminal B BC patients are needed to detect a pCR rate increase from 15% to 40% (α = 0.1 and β = 0.1). At least 3 pCRs must be observed among 8 TNBC patients and 2 among 10 Luminal B patients treated in the 1st stage to move to the 2nd stage. Results: This analysis concerns 3 treated patients from phase Ib and 18 from phase II who received the experimental treatment (median age 55 y-old, 10 TNBC, 11 Luminal B, 14% stage I, 67% stage II, 19% stage III). Overall, 169 AEs were reported and 22 (13%) were graded > 2 on 10/21 patients, including 27% of neutropenia (6/22), 22% of anemia (5/22), 13% of severe asthenia (3/22) and 9% of diarrhea (2/22). Four patients (19%) developed thyroid immune endocrine disorders. Efficacy was evaluated on 18 patients included in the 1st stage of phase II (8 TNBC and 10 luminal B). Five among 8 TNBC patients (62%) and 2 among 10 luminal B patients (20%) had a pCR. Conclusions: The B-immune interim analysis reveals an acceptable global safety profile. Reported immune related adverse events were limited to thyroid endocrine disorders. Observed pCR rate after neoadjuvant paclitaxel followed by 2 durvalumab infusions combined to EC chemotherapy warrants pursuing the trial for the TNBC and luminal B cohorts.

Abstract Objective To investigate the addition of prophylactic G-CSF to each weekly paclitaxel/carboplatin course in patients with recurrent platinum-resistant ovarian (OC), or recurrent or advanced ...endometrial (EC) or cervical carcinoma (CC). Methods 108 patients were enrolled i.e. 36 in each cohort. Eighteen courses of paclitaxel (60 mg/m2 ) and carboplatin (AUC 2.7) were administered weekly. G-CSF (filgrastim) was given to all patients on day 5 (and if needed on day 6). Results For patients with OC, 91% had platinum-resistant and 9% platinum-refractory disease. Median number of prior chemotherapy lines was 3 for OC, 1 for EC, and 1 for CC. Grade 3–4 neutropenia was observed in 34% of patients (95% CI: 26%–44%, P < 0,0001) (OC 29%, EC 36%, CC 38%). This is lower compared to historical data in all cohorts (84%). Confirmed sepsis was observed in 5%, grade 3–4 thrombocytopenia in 41%, grade 2–3 peripheral neuropathy in 17% of patients. In 71% of patients dose was delayed. Dose reduction was necessary for carboplatin in 47% and paclitaxel in 18% of patients. ORR was 51% (OC 48%, EC 45%, CC 58%). Median (95% CI) PFS and OS was 7.1 (5.1–8.1) and 12.7 (10.2–16.3) months, respectively (OC 7 and 13, EC 6 and 19, CC 6 and 14). Conclusion Weekly paclitaxel/carboplatin with G-CSF is an effective treatment with acceptable toxicity in patients with platinum-resistant or platinum-refractory OC, advanced or recurrent EC and CC. The incidence of grade 3–4 neutropenia is lower with the addition of weekly G-CSF compared with earlier studies without routine use of prophylactic G-CSF.

Abstract
Background: Neoadjuvant association of immune checkpoints inhibitors (ICI) and dose dense chemotherapy is promising for triple negative breast cancers (TNBC). However, response rates vary ...from one study to another. Timing, best chemotherapy partner and efficacy in less immunogenic breast cancer (BC), like luminal B tumors, should be further investigated. This study evaluates for TNBC and luminal B HER2(-) BC the neoadjuvant treatment with paclitaxel followed by a short combination of an anti-PD-L1 antibody with anthracyclines. Method B-IMMUNE (NCT03356860), a multicentric phase Ib/II prospective trial, included patients with stage I to III luminal B HER2(-) or TNBC treated with paclitaxel 80mg/m2 weekly from week 1 to 12 followed by 4 cycles of epirubicine 90mg/m2 and cyclophosphamide 600 mg/m2 (EC) Q2W in a neoadjuvant setting. Phase Ib evaluated a single infusion of durvalumab (anti-PD-L1) combined with the 3rd cycle of EC. Phase II evaluated infusions of durvalumab with the 1st and 3rd EC cycles. Surgery was planned 3 weeks after the last EC cycle. Primary objectives were safety and pathological complete response (pCR) rate compared to a historical control. Secondary endpoint was the overall response rate (ORR) based on breast MRI. Eleven patients were enrolled in a control arm without durvalumab, exclusively for translational research purposes. Based on a 2-stage Simon design with an α = 0.1 and β = 0.1, 22 TNBC patients were needed in the phase II to test a null hypothesis of 30% pCR rate against a one-side alternative of 60%, and 24 luminal B BC patients to test a null hypothesis of 15% pCR rate against a one-side alternative of 40% (including an additional accrual margin of 10% for eventual dropouts). At least 9 pCRs had to be observed among the first 20 evaluable TNBC patients and 6 among the first 22 evaluable luminal B patients to rule out the null hypothesis. Results This analysis concerns the 50 patients treated with the experimental treatment, 3 from the phase Ib and 47 from the phase II part. Median age was 51 y-old (31 to 72y), tumor subtypes were 24 TNBC, 25 Luminal B and one sarcoma excluded from the efficacy analysis. Seven (14%) patients had a stage I tumor, 17 (34%) a stage IIA, 13 (26%) a stage IIB, 8 (16%) a stage IIIA, 4 (8%) a stage IIIB and 1 (2%) a stage IIIC. Concerning safety, 232 AEs were reported on 39/50 patients and 34 (14,6%) were graded ≥ 3. The 5 most frequent all-grade AEs were fatigue (8,2%), diarrhea (5,6%), neutropenia (5,2%), anemia and nausea (4,3%). Most frequent grade 3 AEs were anemia and neutropenia (14,7%). Among 4 immune-related adverse events, all were thyroid disorders. One patient died 10 months after the end of treatment due to progressive disease in the liver. Forty-six of the 47 phase II patients were evaluable for efficacy. pCR was reported in 12/22 TNBC patients (55%) and 8/24 luminal B HER2(-) patients (33%). Subgroup analyses based on PD-L1 expression and TILs score are planned. Conclusions The B-IMMUNE study met its primary objective showing a significant improvement in pCR versus the historical control in both TNBC and in Luminal B HER2(-) BC cohorts with the addition of only 2 doses of durvalumab to the anthracyclines. The safety profile is comparable to those previously described with reported immune related adverse events limited to thyroid endocrine disorders.
