Abstract

As part of the single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited Celgene Ltd to submit clinical and cost-effectiveness evidence for paclitaxel as albumin-bound nanoparticles (Nab-Pac) in combination with gemcitabine (Nab-Pac + Gem) for patients with untreated metastatic pancreatic cancer. The STA was a review of NICE's 2015 guidance (TA360) in which Nab-Pac + Gem was not recommended for patients with untreated metastatic pancreatic cancer. The review was prompted by a proposed Patient Access Scheme (PAS) discount on the price of Nab-Pac and new evidence that might lead to a change in the guidance. The Liverpool Reviews and Implementation Group at the University of Liverpool was the Evidence Review Group (ERG). This article summarises the ERG's review of the company's evidence submission for Nab-Pac + Gem, and the Appraisal Committee (AC) decision. The final scope issued by NICE listed three comparators: gemcitabine monotherapy (Gem), gemcitabine in combination with capecitabine (Gem + Cap), and a combination of oxaliplatin, irinotecan, leucovorin and fluorouracil (FOLFIRINOX). Clinical evidence for the comparison of Nab-Pac + Gem versus Gem was from the phase III CA046 randomized controlled trial. Analysis of progression-free survival (PFS) and overall survival (OS) showed statistically significant improvement for patients treated with Nab-Pac + Gem versus Gem. Clinical evidence for the comparison of Nab-Pac + Gem versus FOLFIRINOX and versus Gem + Cap was derived from a network meta-analysis (NMA). Results of the NMA did not indicate a statistically significant difference in OS or PFS for the comparison of Nab-Pac + Gem versus either Gem + Cap or FOLFIRINOX. The ERG's main concerns with the clinical effectiveness evidence were difficulties in identifying the patient population for whom treatment with Nab-Pac + Gem is most appropriate, and violation of the proportional hazards (PH) assumption in the CA046 trial. The ERG highlighted methodological issues in the cost-effectiveness analysis pertaining to the modelling of survival outcomes, estimation of drug costs and double counting of adverse-event disutilities. The AC accepted all the ERG's amendments to the company's cost-effectiveness model; however, these did not make important differences to the incremental cost-effectiveness ratios (ICERs). The company's base-case ICER was £46,932 per quality-adjusted life-year (QALY) gained for the comparison of Nab-Pac + Gem versus Gem. Treatment with Nab-Pac + Gem was dominated both by treatment with Gem + Cap and with FOLFIRINOX in the company's base case. The AC concluded that the most plausible ICER for treatment with Nab-Pac + Gem versus Gem was in the range of £41,000-£46,000 per QALY gained. The AC concluded that Nab-Pac + Gem was not cost effective compared with Gem + Cap or FOLFIRINOX, and accepted that treatment with Nab-Pac + Gem met the end-of-life criteria versus Gem but did not consider Nab-Pac + Gem to meet the end-of-life criteria compared with Gem + Cap or FOLFIRINOX. The AC also concluded that although patients who would receive Nab-Pac + Gem rather than FOLFIRINOX or Gem + Cap were difficult to distinguish, they were identifiable in clinical practice. The AC recommended treatment with Nab-Pac + Gem for patients with untreated metastatic pancreatic cancer for whom other combination chemotherapies were unsuitable and who would otherwise receive Gem.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 April 2018.
All research outputs
#14,574,585
of 23,342,092 outputs
Outputs from PharmacoEconomics
#1,482
of 1,877 outputs
Outputs of similar age
#188,297
of 330,726 outputs
Outputs of similar age from PharmacoEconomics
#35
of 50 outputs
Altmetric has tracked 23,342,092 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,877 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.9. This one is in the 18th percentile – i.e., 18% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 330,726 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 50 others from the same source and published within six weeks on either side of this one. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
