Compared with patients treated with cetuximab–irinotecan, panitumumab-treated patients were significantly older and more likely to have an Eastern Cooperative Oncology Group (ecog) ps of 2 or 3 (27.7% vs. 2.7%, p = 0.001).Other baseline prognostic variables and prior and subsequent therapies ASPECCT study Conclusions .

months (95% CI, 9.4–11.6) in the panitumumab arm and 10.0 months (95% CI, 9.3–11.0) in the cetuximab arm.15 These results indicate noninferior OS in patients with wild-typeKRAS (exon 2) mCRC (panitumumab vs cetuximab hazard ratio [HR], 0.97 [95% CI, 0.84–1.11]). Although the difference in OS between treatments is not statistically Panitumumab and cetuximab are the first anti-EGFR Moabs approved for the treatment of aCRC, showing both of them a similar safety and efficacy profile, when compared to BSC (Tables 2 and 3). Final results from ASPECCT: Randomized phase 3 non-inferiority study of panitumumab (pmab) vs cetuximab (cmab) in chemorefractory wild-type (WT) KRAS exon 2 metastatic colorectal cancer (mCRC).

More specifically, as an immunoglobulin (Ig) G1 isotype mAb, cetuximab can elicit immune functions such as antibody-dependent cell-mediated cytotoxicity involving natural killer cells, T-cell recruitment to the tumor, and T-cell priming via dendritic cell maturation. Panitumumab, an IgG2 isotype mAb, does not possess these immune functions. a randomised phase 3 trial that compared cetuximab and panitumumab in patients with chemotherapy-refractory KRAS exon 2 wild-type colorectal cancer. The results confirm that these drugs can be used interchangeably; however, despite selection of patients based on the almost decade-old knowledge that KRAS exon 2 mutations predict a lack of benefit from anti-EGFR antibodies, the proportion of Findings: The cost-minimization model results demonstrated lower projected costs for patients who received panitumumab versus cetuximab, with a projected cost savings of $9468 (16.5%) per panitumumab-treated patient.

These data suggest that panitumumab and cetuximab are similar in efficacy, and the toxicities of each drug were consistent with prior observations. Panitumumab retained 105·7% (81·9–129·5) of the effect of cetuximab on overall survival seen in this study. The incidence of adverse events of any grade and grade 3–4 was similar across treatment groups.

The occurrence of grade 3–4 infusion reactions was lower with panitumumab than with cetuximab (one [<0·5%] patient vs nine [2%] patients), and the occurrence of grade 3–4 hypomagnesaemia was higher in the panitumumab group (35 [7%] vs 13 [3%]). We recorded one treatment-related fatal adverse event: a lung infection in a patient given Evidence-based recommendations on cetuximab (Erbitux) and panitumumab (Vectibix) for previously untreated RAS wild-type metastatic colorectal cancer in adults.

ASPECCT was a non-inferiority trial (rather than. Background: Over the last few years only one large random-ized phase III study has tried to prospectively assess the safety of cetuximab and panitumumab in a head-to-head comparison. Despite the similar overall toxicity profile, ce-tuximab and Panitumumab vs. Cetuximab Although they both target the EGFR, panitumumab ( IgG2 ) and cetuximab ( IgG1 ) differ in their isotype and they might differ in their mechanism of action. Monoclonal antibodies of the IgG1 isotype may activate the complement pathway and mediate antibody-dependent cellular cytotoxicity (ADCC). [15] ASPECCT study Conclusions .
