12020 Background: Early referral to palliative care was associated with improved health-related quality of life (HRQL) and overall survival (OS) in a US phase 3 trial in lung cancer patients (pts). International studies in mixed cancer types have reported conflicting results. PEARL aimed to determine whether early referral to palliative care would improve HRQL, OS, and resource use in Australian pts with recently diagnosed, advanced thoracic cancers. Methods: Eligible participants (pts) in this unblinded, multi-centre, randomised, phase 3 trial had advanced thoracic cancers diagnosed within 60 days, and the ability to complete patient-rated outcome measures (PROMS). Pts were randomly allocated to early referral to palliative care (ER) or referral at clinician’s discretion (DR). All pts received standard oncological care. PROMS were completed at baseline, every 3-4 weeks for 6 months, then 6-8 weekly. The primary objective was to determine the frequency of sustained, substantial improvements in HRQL, defined as a 5-point improvement in the FACT-L Trial Outcome Index (TOI) maintained for at least 2 consecutive assessments. Secondary outcomes included OS, documentation of advanced care plan (ACP), PROM scores at 12 weeks, anxiety/depression (PROMIS-ED), lung cancer symptoms (FACT-L), global HRQL (ICECAP-SCM), carer-satisfaction and burden, and understanding of illness and prognosis. The accrual target of 200 gave 80% power (alpha 0.05) to detect an absolute improvement of 20% in the proportion of pts achieving the primary endpoint. Results: 113 pts and 78 carers were recruited when the trial closed for slow accrual. Pt characteristics were well balanced: 88 (75%) had NSCLC, 18 (16%) small cell and 7 (6%) mesothelioma. Median age was 69 (IQR 62-74), 63 (56%) were male; systemic anti-cancer therapy ongoing or planned in 88 (78%). Median follow-up was 30 months. First consultations with a palliative care specialist within 60 days of diagnosis occurred in more pts assigned ER vs DR (57% vs 3.5%). Sustained substantial improvements in FACT-L TOI were reported by similar numbers of pts assigned ER vs DR: 33% vs 32%, p = 0.9. OS was similar among those assigned ER versus DR (median 12 vs 18.4 months, p = 0.11). A similar % had a written advanced care plan at death: 15/40 (39%) vs 15/33 (47%). We found no important differences between arms in global HRQL (ICECAP-SCM), depression/anxiety (PROMIS-ED), lung cancer symptoms (FACT-L), carer satisfaction (FAMCARE-2), carer burden (CRA), or understanding of illness by carers or pts. Conclusions: Early referral to palliative care, compared with discretionary referral, did not improve important outcomes for Australian thoracic cancer pts or carers. Our findings suggest that the palliative care needs of such pts were addressed equally well by delayed referral when clinically indicated, resulting in reduced burden for resource-limited specialist palliative services.

Background This multicentre, randomised, double-blinded, placebo-controlled, phase II/III trial aimed to evaluate an oral THC:CBD (tetrahydrocannabinol:cannabidiol) cannabis extract for prevention of refractory chemotherapy-induced nausea and vomiting (CINV). Here we report the phase II component results. Patients and methods Eligible patients experienced CINV during moderate-to-high emetogenic intravenous chemotherapy despite guideline-consistent antiemetic prophylaxis. Study treatment consisted of one cycle of 1–4 self-titrated capsules of oral THC 2.5 mg/CBD 2.5 mg (TN-TC11M) three times daily, from days −1 to 5, and 1 cycle of matching placebo in a crossover design, then blinded patient preference for a third cycle. The primary end point was the proportion of participants with complete response during 0–120 h from chemotherapy. A total of 80 participants provided 80% power to detect a 20% absolute improvement with a two-sided P value of 0.1. Results A total of 81 participants were randomised; 72 completing two cycles were included in the efficacy analyses and 78 not withdrawing consent were included in safety analyses. Median age was 55 years (range 29–80 years); 78% were female. Complete response was improved with THC:CBD from 14% to 25% (relative risk 1.77, 90% confidence interval 1.12–2.79, P = 0.041), with similar effects on absence of emesis, use of rescue medications, absence of significant nausea, and summary scores for the Functional Living Index-Emesis (FLIE). Thirty-one percent experienced moderate or severe cannabinoid-related adverse events such as sedation, dizziness, or disorientation, but 83% of participants preferred cannabis to placebo. No serious adverse events were attributed to THC:CBD. Conclusion The addition of oral THC:CBD to standard antiemetics was associated with less nausea and vomiting but additional side-effects. Most participants preferred THC:CBD to placebo. Based on these promising results, we plan to recruit an additional 170 participants to complete accrual for the definitive, phase III, parallel group analysis.

12008 Background: The aim of this multi-centre, randomised, double-blinded, placebo-controlled, phase 2/3 trial is to determine efficacy of addition of oral cannabis in adults with any malignancy of any stage, experiencing CINV during moderate-highly emetogenic intravenous chemotherapy, despite guideline-consistent anti-emetic prophylaxis, requiring ≥ 2 chemotherapy cycles. Here we report the crossover phase 2 component results. Methods: Treatment consisted of 1 cycle of oral THC 2.5mg/CBD 2.5mg (TN-TC11M) capsules tds days -1 to 5 and 1 cycle matching placebo in a crossover design, then blinded patient preference for a 3rd cycle. Primary end-point is difference in proportion of patients with ‘complete response’ (no emesis & no use of rescue medications) during 0-120 hours from chemotherapy between cycles. 80 patients provides 80% power with 2p of 0.1 to detect a 20% difference. Results: 81 patients recruited (2016-9). 72 completing 2 cycles are included in efficacy analyses. 78 not withdrawing consent are included in safety analyses. Median age was 55 years (range 29-80), 78% were female, 42% report historic cannabis use, 55% were treated with curative intent. Most common regimens were AC (26%), FOLFOX (17%). All received steroids & 5-HT3 antagonist, 79% received NK-1 antagonist, 4% received olanzapine. Efficacy is shown in table. 83% preferred cannabis to placebo. Most common bothersome cannabinoid-related adverse events (cannabis, placebo) were sedation (19%,4%), dizziness (10%,1%), disorientation (3%,0%). No SAEs were attributed to THC/CBD. Conclusions: Addition of oral THC/CBD to standard anti-emetics was associated with less nausea & vomiting but additional side effects. Most preferred THC/CBD to placebo. Based on these positive results, the definitive parallel phase 3 trial component continues (additional n=170). Acknowledgements: Trial participants, investigators, research staff.

TPS9631 Background: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have proven remarkably effective in the treatment of advanced EGFR mutant non-small cell lung cancer (NSCLC). However, drug resistance is inevitable and outcomes with subsequent platinum-pemetrexed chemotherapy are poor. The role of immune-checkpoint inhibitor monotherapy in EGFR mutant NSCLC remains uncertain with trials demonstrating inferior survival outcomes compared to chemotherapy. However, a recent randomised study with combination checkpoint inhibitor-chemotherapy demonstrated improved survival over chemotherapy alone in this patient population. This study aims to evaluate the efficacy and tolerability of combination dual immune-checkpoint blockade, durvalumab and tremelimumab, with platinum-pemetrexed chemotherapy in metastatic EGFR mutant NSCLC following progression on EGFR-TKIs. Methods: This international phase II cohort study will recruit 100 participants from Australia and Taiwan with advanced EGFR mutant NSCLC following disease progression with EGFR-TKIs [Cohort 1 (n=50): T790M mutation negative on tissue and plasma; Cohort 2 (n=50): T790M mutation positive on tissue and/or plasma, and progression on3rd generation TKIs]. Participants will receive 4 cycles of induction durvalumab 1500mg and tremelimumab 75mg with platinum-pemetrexed chemotherapy every 3 weeks, followed by maintenance durvalumab 1500mg and pemetrexed 500mg/m2 every 4 weeks until disease progression. Response will be assessed at 6 and 12 weeks, then 8-weekly during the first year, and 12-weekly thereafter. Major endpoints include objective tumour response rate (OTRR; RECIST1.1; primary), disease control rate, OTRR (iRECIST), progression-free survival, overall survival, and adverse events. Correlative studies include biomarker assessment as potential predictive/prognostic factors. ILLUMINATE is a collaboration between the Australasian Lung Cancer Trials Group, National Health Research Institutes (Taiwan) and the NHMRC Clinical Trials Centre, University of Sydney. As of 6/2/2020, 11 of planned 100 participants have been recruited. Clinical trial information: NCT03994393 .

Although medicinal cannabis can now be prescribed for CINV, high quality clinical trialevidence is required to determine its efficacy and safety. Refereed/Peer-reviewed

IntroductionChemotherapy-induced nausea and vomiting (CINV) remains an important issue for patients receiving chemotherapy despite guideline-consistent antiemetic therapy. Trials using delta-9-tetrahydrocannabinol-rich (THC) products demonstrate limited antiemetic effect, significant adverse events and flawed study design. Trials using cannabidiol-rich (CBD) products demonstrate improved efficacy and psychological adverse event profile. No definitive trials have been conducted to support the use of cannabinoids for this indication, nor has the potential economic impact of incorporating such regimens into the Australian healthcare system been established. CannabisCINV aims to assess the efficacy, safety and cost-effectiveness of adding TN-TC11M, an oral THC/CBD extract to guideline-consistent antiemetics in the secondary prevention of CINV.Methods and analysisThe current multicentre, 1:1 randomised cross-over, placebo-controlled pilot study will recruit 80 adult patients with any malignancy, experiencing CINV during moderate to highly emetogenic chemotherapy despite guideline-consistent antiemetics. Patients receive oral TN-TC11M (THC 2.5mg/CBD 2.5 mg) capsules or placebo capsules three times a day on day −1 to day 5 of cycle A of chemotherapy, followed by the alternative drug regimen during cycle B of chemotherapy and the preferred drug regimen during cycle C. The primary endpoint is the proportion of subjects attaining a complete response to CINV. Secondary and tertiary endpoints include regimen tolerability, impact on quality of life and health system resource use. The primary assessment tool is patient diaries, which are filled from day −1 to day 5. A subsequent randomised placebo-controlled parallel phase III trial will recruit a further 250 patients.Ethics and disseminationThe protocol was approved by ethics review committees for all participating sites. Results will be disseminated in peer-reviewed journals and at scientific conferences.Drug supplyTilray.Protocol version2.0, 9 June 2017.Trial registration numberANZCTR12616001036404; Pre-results.

Pilot and definitive randomised double-blind placebo-controlled trials evaluating an oral cannabinoid-rich THC/CBD cannabis extract for secondary prevention of chemotherapy-induced nausea and vomiting (CINV).Background: Up to half of patients receiving moderate-to-highly emetogenic chemotherapy experience CINV despite optimal anti-emetic prophylaxis. Limited evidence suggests that tetrahydrocannabinol-based (THC) cannabinoid medications may reduce CINV, and addition of cannabidiol (CBD) may improve efficacy and tolerance. The aim of this multi-centre, randomised, placebo-controlled, phase II/III trial is to determine efficacy of addition of an oral cannabinoid-rich THC/CBD cannabis extract for control of CINV.Methods: Target population is adult patients experiencing CINV during moderate and highly emetogenic chemotherapy regimens despite guideline-consistent prophylaxis, scheduled to receive at least 2 more consecutive cycles (A, B and, where applicable, C). Treatment consists of oral THC 2.5mg/CBD 2.5mg (Tilray TN-TC11M) capsules or placebo TDS days -1 to 5, in addition to guideline-consistent anti-emetics, including rescue medications. In the pilot trial (N=80), subjects are randomised for cycle A, with cross-over for cycle B, and preferred treatment for cycle C. In the planned definitive trial (N=250), subjects are randomised to investigational product or placebo for cycles A, B and C in a parallel design (Figure 1). The primary end-point is the proportion of patients gaining a complete response (no emesis and no use of rescue medications) (0 u2013 120h), with additional efficacy end-points of (i) complete response, (ii) no emesis, (iii) no significant nausea and (iv) no use of rescue medication during the a) acute, b) delayed, and c) overall phases of cycle A, B and C, (iv) adverse events, (v) quality of life, and (vi) cost-effectiveness.

The majority of regulated residential aged care in Australia is provided by faith-based providers, with the Catholic Church in Australia providing one in ten of all such services. Despite challenges caused by the decline in active involvement of clergy and religious and government regulatory and financial constraints, pastoral care in Catholic residential aged care is present, evolving, and thriving. Fostering a holistic pastoral environment is also essential to the viability and effectiveness of pastoral care in aged care. A new approach to government funding is needed to foster innovation and a holistic response to the needs of older Australians.

This article argues that the legitimacy of peacekeeping forces in the eyes of the local actors impacts significantly on the success of the peacekeeping operations. Legitimacy not only provides the basis for consent, it has the additional benefit of generating support from local actors. This article uses the 1993 Australian peacekeeping operation in Baidoa, Somalia, and the UNTAC operation in Cambodia as case studies to explore peacekeeper legitimacy and its effect on operational success.
