Abstract 4465


The outcome for patients with unresectable or metastatic soft tissue sarcoma (STS) is poor. Following failure from first-line doxorubicin based chemotherapy no standard therapy has been established. Combination treatment with docetaxel/gemcitabine (gem) has emerged as an effective regimen but administration is limited to fit patients only due to the toxicity profile. Nanoparticle albumin bound paclitaxel (nab-PC) was invented for avoidance of the toxicities related to polyethylated castor oil. In this context, we want to evaluate toxicity and antitumor effect of biweekly nab-PC 150mg/m2 / gem 1000mg/m2 administration in STS patients.


We conducted this proof-of-concept phase I trial to assess the safety of biweekly nab-PC/gem administration in the 2nd and 3rd line setting of STS.


As of 1 April 2019, 6 pts were treated within the phase I. Three pts were male (50%); median age was 67 yrs (range 44 – 72). The current total number of biweekly doses received is 29 (median biweekly doses per patient is 5, range 2 – 7). One dose reduction due to skin toxicity occurred. 3 pts remain on study, 3 stopped treatment due to treatment unrelated reasons (refusal, death unrelated to progression or toxicity and investigator’s decision). The most common treatment-emergent AEs Gr1-2 were fatigue (3 pts), alopecia (3 pts), and neutropenia (2 pts). There were no dose-limiting toxicities or discontinuations due to AEs. We were able to confirm the tolerability of the regimen and are currently accruing patients to a prospective single arm phase II trial. Treatment will be given biweekly until progression, unacceptable toxicity or patient withdrawal. The primary endpoint of the trial is progression-free rate (PFR) at 12 weeks. Secondary endpoints are PFS, overall survival and symptom-specific quality of life. A total of 8 Swiss sites will participate for a total of 37 patients, as required by Simon’s two-stage design.


These preliminary results indicate that biweekly administration of nab-PC/gem was well tolerated. The phase I established dose and schedule were selected for further evaluation in phase II trial.
