Combination therapy with docetaxel and mSTAR1302 elicits antitumor effects in triple negative breast cancer (4T1) and androgen-independent prostate cancer (TRAMP-C2) mouse models. (A–E) 8–12-week-old female Balb/c mice were inoculated subcutaneously with 5x10 4 4T1 in the mammary fat pad (n=8–10 per group). (A) pictogram depicts experimental design. When the tumors reached 40-70mm 3 , mice were administered 3 doses of mSTAR1302 (1 mg/kg, i.p.) once per week on days 9, 16, and 23 and 3 doses of docetaxel (500 µg, i.p.), every other day, 7 days post-initial mSTAR1302 treatment, on days 16, 18, and 20. Primary tumors were measured in terms of mean (B) and individual (C) tumor volumes, as depicted. Inset numbers are tumor-free mice. In two additional cohorts, to assess metastatic growth, lungs were removed from 4T1 tumor-bearing mice 28 days post-tumor inoculation following the same treatment schedule. Lungs were dissociated, cultured in medium (2x FBS with 6-thioguanine) and incubated at 37 °C with 5% CO 2 for 12 days. (D) a meta-analysis from two separate studies is depicted with closed and opened circles differentiating data collected from each study. Cell colonies representing lung metastases were stained with 0.05% methylene blue and counted for each treatment group (n=14–20 per group total). Survival (E) was measured over time with inset numbers depicting median overall survival (mOS) and shaded bands depicting 95% confidence intervals. (F–I) 8–12-week-old male C57bl/6 mice were inoculated subcutaneously with 2.5x10 6 TRAMP-C2, on the right flank (n=8–10 per group). (F) pictogram depicts experimental design. Mice were administered mSTAR1302 (1 mg/kg, i.p.) when tumors reached 70–100mm 3 on days 22, 29, and 36, and docetaxel (500 µg, i.p.) on days 29, 31, and 33. Tumors were measured with mean (G) and individual (H) tumor volumes depicted. Inset numbers are tumor-free mice. Survival (I) was measured over time with mOS and 95% confidence intervals (shaded bands) depicted. Statistical tests: tumor growth: two-way ANOVA with Tukey’s post hoc test; comparison between groups: one-way ANOVA with Tukey’s post hoc test; survival; Mantel-Cox test.

Docetaxel induces upregulation of death receptors TRAIL-R2 and FAS in 4T1 and TRAMP-C2 cells. (A) 4T1 and TRAMP-C2 cells were treated in vitro with either no drug or docetaxel (250 ng/mL) for 48 hours and analyzed for surface expression of FAS and TRAIL-R2 via flow cytometry. Histograms indicating frequency and gMFI are shown. Experiment repeated twice with similar results. (B) 4T1 and TRAMP-C2 cells were treated as described in <xref ref-type=

Figure 1A and then co-cultured with TRAIL ligand or FAS ligand and protein G and measured for relative cell lysis compared to cells alone. (C, D) tumors harvested on day 28, after treatment as described in Figure 1A , were fixed for multiplex immunofluorescence staining and quantified for CD8 (green) and TRAIL-R2 or FAS (red) expression. (E) differential gene expression was interrogated using NanoString murine PanCancer immune profiling panel on tumors harvested on day 23 from 4T1 tumor-bearing Balb/c female mice, following treatment as previously described. Fold change compared to untreated tumors reported for TRAIL and FAS ligands. (F) 4T1 cells were exposed to docetaxel (250 ng/mL) for 48 hours and co-cultured with NK cells isolated from tumor-free Balb/c mice (E:T = 25:1) and monitored for relative NK-specific lysis of tumor cells for up to 8 hours post-effector addition.
