2. nab® -paclitaxel is the first tumour-targeted nanomedicine to leverage the natural transport properties of albumin1
A single molecule of albumin can bind up to 6 or 7 molecules of paclitaxel6
nab® -paclitaxel individual molecule
nab® -paclitaxel complex
4–14 nm in size3–5
Albumin
Paclitaxel
It is important to note the sizes of the nab®-paclitaxel complex (130 nm) and individual molecules (4–14 nm).1–4
Modelling and in vivo studies have shown that drug penetration by nanomedicines depends on the size of pores within vasculature.1
Tumour vasculature is leaky and contains large pores of heterogeneous size.1
Smaller nanomedicines demonstrate the most rapid penetration across a range of pore sizes.5
As such, the small size of individual nab®-paclitaxel molecules has the potential to facilitate effective drug delivery to tumours.

Compared with sb-P/C, treatment with nab-P/C resulted in significantly less grade 3/4 neutropenia
An increased incidence of thrombocytopenia and anemia with the nab-P/C regimen was observed, and these toxicities were readily manageable
Most anemia was corrected with a single blood transfusion; thrombocytopenia did not lead to increased rates of hemorrhage

13. Subanalysis in the Maintenance Setting of the Phase III CA031 Trial
Objective and Patient Population
Objective: This exploratory analysis examined outcomes in patients with squamous cell carcinoma (SCC) histology receiving > 4 cycles of nab-P/C
229 patients with SCC NSCLC received nab-P/C in induction phase (first 4 cycles)
138 of 229 patients (60.3%) treated with nab-P/C were progression free at cycle 4 and entered cycle 5; median PFS and OS were evaluated for these patients and expressed from day 1 of cycle 5

Elderly pts and pts with ECOG PS 2 have poorer prognosis than younger pts or those with better PS
Both subgroups underrepresented in randomized clinical trials due to concerns about tolerability and comorbidities
ABOUND.PS2 evaluated safety, efficacy of nab-paclitaxel + carboplatin followed by nab-paclitaxel in chemotherapy-naive pts with advanced NSCLC and PS 2[1]
ABOUND.70+ evaluated safety, efficacy of nab-paclitaxel + carboplatin in chemotherapy-naive pts aged 70 yrs or older with advanced NSCLC[2]
