    Testing for Homologous Recombination Repair or Homologous Recombination Deficiency for Poly (ADP-ribose) Polymerase Inhibitors: A Current Perspective

    Get PDF
    Poly (ADP-ribose) polymerase inhibitors (PARPis) have demonstrated clinical activity in patients with BRCA1 and/or BRCA2 mutated breast, ovarian, prostate, and pancreatic cancers. Notably, BRCA mutations are associated with defects in the homologous recombination repair (HRR) pathway. This homologous recombination deficiency (HRD) phenotype can also be observed as genomic instability in tumour cells. Accordingly, PARPi sensitivity has been observed in various tumours with HRD, independent of BRCA mutations. Currently, four PARPis are approved by regulatory agencies for the treatment of cancer across multiple tumour types. Most indications are specific to tumours with a confirmed BRCA mutation, mutations in other HRR-related genes, HRD evidenced by genomic instability, or evidence of platinum sensitivity. Regulatory agencies have also approved companion and complementary diagnostics to facilitate patient selection for each PARPi indication. This review aims to summarise the biological basis, clinical validation, and clinical relevance of the available diagnostic methods and assays to assess HRD

    Background: Vandetanib (ZACTIMA (TM); ZD6474) is a once-daily, oral inhibitor of vascular endothelial growth factor receptor and epidermal growth factor receptor signaling. The safety and tolerability of vandetanib plus pemetrexed was assessed in patients with advanced non-small-cell lung cancer (NSCLC). Patients and methods: Patients with previously treated NSCLC (stage IIIB/IV) received once-daily oral vandetanib (100 or 300 mg) with pemetrexed (500 mg/m(2) i.v. infusion every 21 days). Results: Patients received vandetanib 100 mg + pemetrexed (n = 10) or vandetanib 300 mg + pemetrexed (n = 11). The protocol definition of a tolerable dose [vandetanib-related dose-limiting toxicity (DLT) in less than 2 patients] was met in both dose cohorts, with one DLT reported in each: asymptomatic QTc prolongation (> 100 ms increase from baseline, but absolute QTc < 500 ms) in the 100 mg cohort and interstitial lung disease, which resolved after steroid therapy, in the 300 mg cohort. The most common adverse events were rash, anorexia, fatigue and diarrhea (all n = 10). Conclusion: Vandetanib and pemetrexed in combination were generally well tolerated in patients with advanced NSCLC

    A phase I study of Vandetanib in combination with vinorelbine/cisplatin or gemcitabine/cisplatin as first-line treatment for advanced non-small cell lung cancer

    INTRODUCTION Vandetanib is a once-daily oral agent that selectively inhibits vascular endothelial growth factor receptor, epidermal growth factor receptor, and RET (REarranged during Transfection) signaling. METHODS This Phase I study investigated the safety, tolerability, and pharmacokinetics of vandetanib when administered with either gemcitabine plus cisplatin (GC) or vinorelbine plus cisplatin (VC) in patients with previously untreated locally advanced or metastatic non-small cell lung cancer. RESULTS Seventeen patients received vandetanib 100 mg/d plus VC (n = 9) or GC (n = 8). Three dose-limiting toxicities were reported in each treatment group: vandetanib + VC (pulmonary artery thrombosis and asymptomatic QTc prolongation [n = 2]); vandetanib + GC (peripheral ischemia [due to arterial occlusion], pulmonary embolism, and limb venous thrombosis). The protocol definition of a tolerable dose was not met, and no patients were recruited to receive vandetanib 300 mg plus VC or GC. There was no apparent pharmacokinetic interaction between vandetanib and vinorelbine or gemcitabine, but there was an approximate 30% increase in the exposure to cisplatin, which may be due to accumulation of total platinum and/or an interaction with vandetanib. CONCLUSIONS In this study, in patients with previously untreated advanced non-small cell lung cancer, vandetanib 100 mg/d in combination with either VC or GC was not tolerated

    Purpose Vandetanib is a once-daily oral inhibitor of vascular endothelial growth factor receptor and epidermal growth factor receptor signaling. This randomized, placebo-controlled phase III study assessed the efficacy of vandetanib plus pemetrexed as second-line therapy in advanced non–small-cell lung cancer. Patients and Methods Patients (N = 534) were randomly assigned to receive vandetanib 100 mg/d plus pemetrexed 500 mg/m2 every 21 days (n = 256) or placebo plus pemetrexed (n = 278). Progression-free survival (PFS) was the primary end point; overall survival, objective response rate, disease control rate, time to deterioration of symptoms, and safety were secondary assessments. Results There was no significant difference in PFS between treatment arms (hazard ratio [HR], 0.86; 97.58% CI, 0.69 to 1.06; P = .108). Overall survival was also not significantly different (HR, 0.86; 97.54% CI, 0.65 to 1.13; P = .219). Statistically significant improvements in objective response rate (19% v 8%; P &lt; .001) and time to deterioration of symptoms (HR, 0.71; P = .0052; median, 18.1 weeks for vandetanib and 12.1 weeks for placebo) were observed in patients receiving vandetanib. Adding vandetanib to pemetrexed increased the incidence of some adverse events, including rash, diarrhea, and hypertension, while showing a reduced incidence of nausea, vomiting, anemia, fatigue, and asthenia with no reduction in the dose intensity of pemetrexed. Conclusion This study did not meet the primary end point of statistically significant PFS prolongation with vandetanib plus pemetrexed versus placebo plus pemetrexed. The vandetanib combination showed a significantly higher objective response rate and a significant delay in the time to worsening of lung cancer symptoms versus the placebo arm as well as an acceptable safety profile in this patient population. </jats:sec

    Cediranib in combination with olaparib in patients without a germline BRCA1/2 mutation and with recurrent platinum-resistant ovarian cancer: Phase IIb CONCERTO trial.

    PURPOSE: The efficacy, safety, and tolerability of cediranib plus olaparib (cedi/ola) were investigated in patients with non-germline-BRCA-mutated (non-gBRCAm) platinum-resistant recurrent ovarian cancer (OC). PATIENTS AND METHODS: PARP inhibitor-naïve women aged ≥18 years with platinum-resistant non-gBRCAm OC, ECOG performance status of 0-2, and ≥3 prior lines of therapy received cediranib 30 mg once daily plus olaparib 200 mg twice daily in this single-arm, multicenter, Phase IIb trial. The primary endpoint was objective response rate (ORR) by independent central review (ICR) using RECIST 1.1. Progression-free survival (PFS), overall survival (OS), and safety and tolerability were also examined. RESULTS: Sixty patients received cedi/ola, all of whom had confirmed non-gBRCAm status. Patients had received a median of four lines of chemotherapy; most (88.3%) had received prior bevacizumab. ORR by ICR was 15.3%, median PFS was 5.1 months, and median OS was 13.2 months. Forty-four (73.3%) patients reported a grade ≥3 adverse event (AE), with one patient experiencing a grade 5 AE (sepsis), considered unrelated to the study treatment. Dose interruptions, reductions, and discontinuations due to AEs occurred in 55.0%, 18.3%, and 18.3% of patients, respectively. Patients with high global loss of heterozygosity (gLOH) had ORR of 26.7% (4/15; 95% CI 7.8-55.1%), while ORR was 12.5% (4/32; 95% CI 3.5-29.0%) in the low gLOH group. CONCLUSIONS: Clinical activity was shown for the cedi/ola combination in heavily pretreated, non-gBRCAm, platinum-resistant patients with OC despite failing to meet the target ORR of 20%, highlighting a need for further biomarker studies
