Background: Bavdegalutamide (ARV-110) is a novel, oral PROteolysis TArgeting Chimera (PROTAC) protein degrader that targets wild-type androgen receptor (AR) and clinically relevant mutants. Bavdegalutamide demonstrated tumor growth inhibition in multiple xenograft models (eg, AR gene amplification, AR mutation, enzalutamide resistance, and enzalutamide insensitivity). In a phase 1/2 study (NCT03888612), bavdegalutamide showed clinical activity in patients with metastatic castration-resistant prostate cancer (mCRPC) who had previously received 1–2 prior novel hormonal agents (eg, abiraterone and/or enzalutamide), including heavily pretreated patients. Abiraterone is approved, in combination with a corticosteroid, to treat patients with mCRPC or with high-risk castration-sensitive prostate cancer (CSPC). Up to a third of patients treated with abiraterone develop primary resistance to this drug and nearly all patients experience disease progression. Here we describe a phase 1b study that will evaluate the combination of bavdegalutamide with abiraterone at the initiation of progression on abiraterone (prostate-specific antigen [PSA] progression without radiographic progression) to test if the addition of bavdegalutamide will overcome resistance to abiraterone and re-establish the AR pathway blockade in patients with prostate cancer. Methods: Eligible patients are men ≥18 years of age with histologically, pathologically, or cytologically confirmed adenocarcinoma of the prostate and Eastern Cooperative Oncology Group performance status of 0 or 1. Patients must be receiving ongoing treatment with stable doses of abiraterone and a concomitant corticosteroid for mCRPC or CSPC and have PSA progression ≥16 weeks after initiation of abiraterone, ≥2 rising PSA values measured ≥1 week apart, and no radiographic evidence of disease progression while receiving abiraterone. Ongoing androgen deprivation therapy with a gonadotropin-releasing hormone analogue or inhibitor or orchiectomy is required. Prior treatment with enzalutamide, apalutamide, darolutamide, or experimental AR-directed therapies is not permitted. Bavdegalutamide, abiraterone, and a corticosteroid will be administered daily in 28-day cycles. Primary objectives are to evaluate the safety and tolerability of bavdegalutamide plus abiraterone and determine the recommended phase 2 dose and schedule of this combination (based on the incidence of first-cycle dose-limiting toxicities and the frequency and severity of adverse events and laboratory abnormalities).

Background: Two third of patients with OC, have an advanced stage at initial diagnosis accompanied with poor prognosis. Results from landmark trials of maintenance therapy (MTX) with poly ADP ribose polymerase inhibitors (PARPi), especially in tumors associated with homologous recombination deficiency (HRD), like BRCA-mutated tumors, led to the strong recommendation on testing and treatment procedures in the clinical routine in patients newly diagnosed with advanced high-grade epithelial OC. The translation of these guidelines into clinical routine affects care management and therefore needs to be evaluated. This study aims to gain new insights into current real-world biomarker testing and 1L-treatment patterns together with clinical and patient-reported outcomes of patients with newly diagnosed advanced OC in Germany and to capture the influence of 1L treatment (with or without PARPi MTX) on medical routine and patient needs. Methods: SCOUT-1 is a national prospective, observational study (NCT04830709) to collect clinical real-world and patient-reported outcome (PRO) data in patients newly diagnosed with histologically confirmed advanced (FIGO stage III or IV) high-grade epithelial ovarian, fallopian-tube, or primary peritoneal cancer in Germany. Selection criteria include written informed consent, completed surgery (if applicable), eligible for platinum-based chemotherapy, BRCA1/2 mutation tested and willingness/ability to report PROs electronically. About 750 patients are planned to be included in up to 80 sites (hospitals or office-based). The primary objective is to determine the effectiveness of standard treatment sequences by estimating progression-free survival according to investigator’s assessment. Further focus is to describe biomarker-testing algorithm, patient selection and to assess patients’ QoL, symptoms, needs, as well as patients’ expectations. Importantly, SCOUT-1 will help to collect long-term data as patients will be followed for up to 7 years. First-subject-was included in the study in June 2021. Study completion date is planned in Q2 2032.

Background: Low-grade serous ovarian cancer (LGSOC) represents a minority within the group of invasive epithelial ovarian malignancies. Recent analyses showed a very limited responsiveness to chemotherapy in LGSOC. Since bevacizumab many years ago, none other agents have been approved in LGSOC. There is a high demand of new therapy combinations with modern substances to improve the response rate and prognosis in this group of patients. Immune check-point inhibitors provide a new possibility which showed to be effective in different malignant diseases as well as in selected ovarian cancer patients. In this study, the standard chemotherapy is going to be combined with pembrolizumab in recurrent LGSOC cases with therapy free interval (TFI) over 6 months after last platinum-based chemotherapy. To the authors knowledge no comparable studies have been performed or planned. If our trial should show pembrolizumab effectivity in LGSOC, it would be a signal and impulse for future clinical studies in this rare disease. Methods: PERCEPTION/NOGGO-ov44 (NCT04575961) clinical trial is a multi-center, single-arm phase 2 study to evaluate pembrolizumab therapy concomitant to platinum-based chemotherapy (carboplatin plus pegylated liposomal doxorubicin, carboplatin plus gemcitabine or carboplatin monotherapy) and as maintenance in recurrent low-grade serous ovarian cancer cases. LGSOC patients with progression or recurrence at least six months after most previous platinum-containing therapy and in good general performance (ECOG 0 or 1) are eligible to participate in this clinical trial. The primary objective is the 12 months progression free survival (PFS) rate. Secondary end-points include overall survival, response rate (RR), PFS and RR according to Ki67 expression levels, time to first subsequent therapy (TFST) and its response, safety and quality of life. The trial is planned according to Simon’s two-stage design with total sample size up to 33 patients. The null hypothesis is PFS-rate after 12 months of 20%. In the first phase 18 patients will be enrolled and if at least 5 patients show PFS after 12 months the study is going to be continued with an additional 15 patients. The trial is claimed successful, if at least 11 patients show PFS after 12 months. Assuming a true PFS-rate of 40%, this trial has 5% type I error rate and 80% power.

Background: Early stage invasive squamous cell carcinoma of the vulva is treated by radical excision of the primary tumor combined with a sentinel node (SN) procedure for the groins. GROINSS-VI and GOG-173 demonstrated that if there is no metastasis to the SN, then standard of care is observation. GROINSS-VII/GOG-270 demonstrated that micrometastatic disease (<2mm) to the SN requires standard radiotherapy (50 Gy) without the need for an inguinofemoral lymphadenectomy (IFL). This study also found that patients with macrometastasis ( > 2mm) required IFL in order to have an acceptably low groin recurrence rate. However, IFL is associated with significant morbidity such as lymphedema, wound healing issues, and recurrent infections. It is hypothesized that for those with macrometastasis ( > 2 mm) in the SN, the efficacy of treatment can be increased by giving a higher dose of radiotherapy along with chemosensitization. Methods: This is an international multicenter single-arm phase II prospective clinical trial. The primary objective is to investigate the safety of replacing IFL by chemoradiation in early-stage vulvar cancer patients with a macrometastasis ( > 2mm) and/or extracapsular extension in the SN. The primary endpoint is the groin recurrence rate in the first two years after primary treatment. Secondary endpoints are short and long-term morbidity associated with the SN procedure and chemoradiation and quality of life as measured by EORTC-QLQc30. Patients with invasive ( > 1mm) squamous cell carcinoma of the vulva, stage T1, tumor size < 4 cm diameter and no suspicious lymph nodes by imaging of the groins will proceed with SN detection. Institutions enrolling patients must demonstrate prior surgical experience with SN detection with the submission of at least 10 successfully completed cases in vulvar cancer. Patients with SN metastases > 2mm and/or with extracapsular extension or those with > 1 SN with micrometastases will be eligible for this study. Treatment will consist of chemoradiation with a dose of 56 Gy to the groin combined with weekly cisplatin 40 mg/m2 IV on days 1, 8, 15, 21 and 29 of radiotherapy. One hundred and fifty-seven patients in Europe, United States and Canada will be enrolled. The study includes continuous monitoring of groin recurrences with stopping rules. Results of this trial may be practice changing and eliminate the need for IFL in all women with clinically early stage vulvar cancer. The study is currently open for enrollment. Clinical trial information: NCT05076942.

Background: Understanding connections between key cellular pathways is particularly important when selecting combinatorial cancer therapies. HRAS preferentially activates PI3K 5-fold more efficiently than KRAS, while KRAS is a more efficient activator of RAF (Yan et al. 1998). Further, mutant HRAS is insufficient for oncogenic transformation if it is unable to recruit PI3K in preclinical models (Gupta et al. 2007). Conversely, mutant PI3K requires RAS to drive tumor growth (Zhao and Vogt 2008). HRAS mutation/overexpression and PIK3CA mutations/amplifications account for up to 50% of head and neck squamous cell carcinoma (HNSCC). Recognition of these interdependencies was the basis for the evaluation of HNSCC PDX models which demonstrated additive or synergistic anti-tumor effects that confirmed the codependency of these pathways, thus providing robust rationale for investigating combined pathway inhibition in the clinic. The KURRENT trial is enrolling patients with HRAS and/or PIK3CA-dependent tumors who will receive combination treatment with tipifarnib (a potent and selective inhibitor of farnesyltransferase, a critical enzyme for HRAS activity) and alpelisib, a PI3K inhibitor. Methods: The KURRENT trial (KO-TIP-013, NCT04809233) is an ongoing multicenter, open-label, 2-cohort, phase 1/2 trial designed to evaluate the safety of the combination of tipifarnib and alpelisib, determine the recommended combination dose(s) regimen, and evaluate preliminary anti-tumor activity in patients with recurrent/metastatic (R/M) HNSCC whose tumors are dependent upon HRAS and/or PIK3CA signaling. The trial will enroll 40 HNSCC patients; 20 each into two biomarker defined cohorts (Cohort 1; PIK3CA; Cohort 2; HRAS). Participants must have documented treatment failure from at least one prior therapy in the R/M setting and have measurable disease by RECIST v1.1. At the starting dose level, participants will receive tipifarnib at 300 mg twice daily on days 1-7 and 15-21 and alpelisib 200 mg each morning continuously during a 28-day cycle. The trial will use an adaptive dose escalation design (based on a Bayesian logistic regression model) to characterize safety, tolerability, and clinical activity of the combination to identify the Optimal Biologically Active Dose (OBAD) while maintaining a dose limiting toxicity (DLT) rate < 33%. No formal interim analysis is planned as the model-based dose escalation process requires decisions based on real-time evaluation of aggregate toxicity and efficacy data. All observed/available data among each cohort will be evaluated before choosing the combination dose for a subsequent cohort. Enrollment into the PIK3CA cohort began in October 2021. Clinical trial information: NCT04809233.

Background: Treatment options for recurrent and/or metastatic (R/M) salivary gland cancer (SGC) are limited with response rates to standard cytotoxic chemotherapy (CT) low at 10-30%, and responses to single-agent immune checkpoint inhibition (ICI) <10%. Current therapeutic agents used to treat R/M SGC have an unfavorable toxicity profile including cytotoxic CTs such as cisplatin and doxorubicin and the targeted therapy lenvatinib. Treatments with general applicability and acceptable side effect profile are urgently needed. Pemetrexed (PTX) is a multi-targeted anti-folate CT with an excellent safety and toxicity profile with promising responses reported in a case series of patients (pts) with R/M SGC (Viscuse P and Price K. Marked responses to pemetrexed chemotherapy for metastatic adenocarcinoma of the parotid gland: case series. Head Neck 2019;41(6):E99-103.). As the combination of PTX and pembrolizumab (PMB) showed enhanced responses and survival in pts with lung cancer, we hypothesize that PTX and PMB will have efficacy in pts with R/M SGC and that the combination will have improved anti-cancer activity compared with historical controls. Correlative studies on archived tissues include methylthioadenosine phosphorylase loss, PDL1 expression, and thymidylate synthase expression as potential biomarkers of response. Methods: MC200708 is a single institution (3-site), open-label, single arm phase II study of PTX and PMB in patients with R/M SGC. Pts will be treated in two cohorts: one for pts with adenoid cystic carcinoma (ACC) and the other for pts with all other types of SGC (non-ACC cohort). Eligible pts must be ≥18 years old, have a pathologically confirmed SGC that is not amenable to curative-intent therapy, ECOG 0-2, adequate organ function, and at least 1 measurable lesion by RECIST 1.1. Any number of lines of prior therapy is allowed; prior treatment with checkpoint inhibitors and/or PTX is allowed. Key exclusion criteria: serious medical co-morbidity or autoimmune disease, prior grade 3-4 adverse event (AE) or grade 2-4 lung AE with ICI, and uncontrolled brain metastases. Simon’s two-stage design will be used for each cohort separately given the expected difference in responses in pts with ACC and non-ACC. Primary endpoint is overall response rate. Secondary endpoints are progression free and overall survival and toxicity. All patients will receive the same treatment of PTX 500 mg/m2 IV + PMB 200 mg IV every 3 weeks until disease progression or treatment intolerance. Response assessments will occur every 3 cycles. Enrollment began July 2021 and 16 of the planned 45 patients (ACC cohort 9 of 20 pts, non-ACC 7 of 25) have been accrued. Clinical trial information: NCT04895735.

Background: Anaplastic thyroid cancer (ATC) is a rare and lethal tumor of thyroid epithelium, with disease-specific mortality approaching 100%. ATC accounts for > 50% of the 1200 annual deaths attributable to thyroid cancer. In the pre-molecular era, treatment options were largely ineffective, reflected in a median overall survival of 3-4 months following diagnosis. Outcomes have improved in BRAF V600E-mutated ATC with the FDA approval of dabrafenib and trametinib (Subbiah et al. JCO, 2018). However, a significant need exists for patients with BRAF wild-type tumors and patients with BRAF-mutated tumors who progress following treatment with BRAF-directed therapies. Abemaciclib is a CDK4/6 inhibitor currently FDA-approved in combination with endocrine therapy for hormone-positive breast cancer. Genomic analyses of ATC have indicated the presence of an intact Rb (Retinoblastoma) expression as well as the existence of CDKN2A (the gene encoding human p16) mutations in up to 32% of patients with ATC (Khan et al., Head Neck, 2019). Moreover, Lee et al. in 2008 reported undetectable p16 levels in 24 out of 27 (89%) patients with ATC. Low p16 levels would be expected to result in accelerated S phase entry, leading to uncontrolled ATC growth. Finally, studies in mouse xenograft models have demonstrated that ribociclib (a CDK4/6 inhibitor) slows proliferation and induces apoptosis of ATC cells (Lee et al., Cancer Letters, 2018). These molecular alterations and pre-clinical data provide a mechanistic rationale by which to evaluate CDK4/6 inhibitors in ATC and, to date, no CDK4/6 inhibitors have been evaluated in thyroid cancer. Methods: This multicenter, single-arm Phase 2 study will evaluate the safety and efficacy of treatment with abemaciclib in patients with histologically confirmed unresectable or metastatic ATC, using an optimal Simon two-stage design. Patients with BRAF V600E+ ATC must have progressed on or have an intolerance to dabrafenib and trametinib. The study intervention is abemaciclib 200 mg orally twice daily. The primary endpoint is overall response rate at eight weeks from the start of treatment. Secondary endpoints include progression-free survival and overall survival. Currently, 6 patients have been enrolled. Planned genomic analysis will be conducted to identify potential predictive biomarkers. Clinical trial information: NCT04552769.

Background: As a latent new subtype, HER2-low-expressing breast cancer has attracted increasing attention. However, HER2-low-expressing/HR-positive early or locally advanced breast cancer (E/LABC) has the lowest pathological complete response (pCR) rate among all types of breast cancer. Pyrotinib, a small-molecule HER1/HER2/HER4 tyrosine kinase inhibitor, combined with chemotherapy regimen showed excellent efficacy and safety in the treatment of patients with HER2-positive early, locally advanced and metastatic breast cancer. In-vitro experiment showed pyrotinib can significantly inhibit colony formation in breast cancer cell lines with different HER2 expression levels including HER2-positive and HER2-low-expressimg [immunohistochemistry (IHC) 2+/in situ hybridization (ISH) negative]. Therefore, the investigator-driven, ongoing PILHLE-001 trial has been conducted to evaluate the potential role of neoadjuvant pyrotinib plus chemotherapy in the treatment of HER2-low-expressing/HR-positive E/LABC, which may provide a novel neoadjuvant therapeutic strategy for these patients. Methods: PILHLE-001, as a single-arm, phase Ⅱ study, is the first trial to evaluate the efficacy and safety of neoadjuvant pyrotinib combine with chemotherapy in HER2-low-expressing (defined as IHC 2+ with ISH negative) and HR-positive (ER or PR > 1% stained cells) E/LABC (cT1c with histologically involved lymph nodes or ≥cT2). Patients who have HER2 IHC 1+, or severe heart diseases or basic gastrointestinal diseases are excluded. The trial has 80% power to detect true difference from previous reported pCR rate of 17.5%, to an expected pCR rate of 35% at two-sided alpha level of 0.05. Considering a drop rate of 10%, a total of 46 patients will be needed. Since May 19, 2021 until now, 19 patients have been enrolled. All eligible patients will receive pyrotinib 320mg orally daily with all chemotherapy cycles (epirubicin 90 mg/m² intravenously plus cyclophosphamide 600 mg/m² intravenously on day 1 for four 3-week cycles followed by docetaxel 100 mg/m² intravenously on day 1 for four 3-week cycle). The primary outcome is the rate of total pCR, defined as no residual invasive tumor cells in the breast and axillary nodes, regardless of ductal carcinoma in situ (ypT0/is ypN0) after neoadjuvant treatment. The secondary outcomes include Miller-Payne grade, residual cancer burden score, overall response rate, breast conservation rate, disease-free survival, overall survival, exploratory biomarkers and drug related safety. Primary efficacy outcomes will be analyzed in the intention‐to‐treat population and safety outcomes in the safety set population. Long-term efficacy outcomes will be assessed later with enough follow-up. Clinical trial information: NCT05165225.

Background: BCL2 inhibition as a means of targeting intrinsic apoptotic pathways that confer a survival advantage to leukemic blasts has become a key therapeutic strategy for patients with myeloid malignancies. LP-108 is an oral highly potent and selective inhibitor of BCL-2 with comparable or more potent in vitro inhibitory activity as compared to the FDA approved oral BCL-2 inhibitor venetoclax. We propose to investigate LP-108 as monotherapy and in combination with azacitidine in patients with relapsed or refractory (r/r) MDS, CMML or AML. Methods: The primary objectives of the trial are 1.) To determine the safety, tolerability and determine the maximum tolerated dose (MTD) and the recommended phase 2 dose / optimal biological dose (OBD) of LP-108 as a single agent (Arm 1) and in combination with azacitidine (Arm 2) in patients with relapsed/refractory MDS/CMML/AML; 2.) To characterize the pharmacokinetic profile of LP-108 as monotherapy and in combination with a fixed dose of azacitidine. The secondary objectives of the trial are 1.) To evaluate the objective response rate of LP-108 (monotherapy or combination therapy) in r/r MDS/CMML/AML as well as progression free survival, duration of response and overall survival. In Arm 1 patients will be enrolled according to a 3+3 design with escalating doses of LP-108 for a 28 day cycle (firs table). DLTs will be determined in the first 28 days. In Arm 2 patients will be enrolled according to a 3+3 design with escalating doses of LP-108 in combination with a fixed dose of azacitidine (second table). DLTs will be determined in the first 28 days. DLT for both arms is defined as some ≥ Grade 3 non-hematological toxicities or prolonged myelosuppression. Patients may continue treatment until disease progression, unacceptable toxicity, or per investigator discretion. Patients age ≥ 18 years with r/r MDS with excess or blasts or with high or very-high risk disease per the R-IPSS, or r/r MDS for Arm 2, r/r AML, or frontline older and/or unfit AML for Arm 2, or r/r CMML may enroll. Patients with prior hypomethylating agents or venetoclax exposure may enroll. The blast count at the time of starting therapy must be ≤ 30 x 109 cells/L. Hydroxyurea is allowed prior to and during treatment. Ejection fraction ≥ 50% is required. Calculated creatinine clearance shall be ≥ 30 mL/min. Strong CYP3A4 inducers and inhibitors are prohibited. Patients on weak/moderate azole antifungals were allowed to enroll. Enrollment to Arm 1 is complete and there have been no DLTs to date. Enrollment to Arm 2 is pending.

Background: Standard of care for SMM includes active monitoring until progression to multiple myeloma (MM); however, recent evidence suggests pts with high-risk features may benefit from early treatment. DARA is a human IgGκ monoclonal antibody targeting CD38 that is approved as monotherapy for relapsed/refractory MM (RRMM) or in combination with standard of care for RRMM or newly diagnosed MM. Results from the phase 3 COLUMBA study showed that DARA SC demonstrated similar efficacy to intravenous (IV) DARA but with a lower rate of infusion-related reactions and shorter administration time. Based on the promising single-agent activity observed with IV DARA in intermediate- or high-risk SMM pts during the phase 2 CENTAURUS study, we hypothesized that DARA SC may delay progression to MM versus active monitoring in pts with high-risk SMM. Methods: AQUILA is an ongoing, randomized, open-label, multicenter phase 3 study of DARA SC versus active monitoring in pts with high-risk SMM. DARA SC (DARA 1,800 mg + recombinant human hyaluronidase PH20 [rHuPH20; 2,000 U/mL; Halozyme]) is administered by manual injection over approximately 5 minutes at alternating locations on the abdomen weekly in Cycles 1 and 2, every 2 weeks in Cycles 3-6, and every 4 weeks thereafter until 39 cycles (28 days/cycle), up to 36 months, or until disease progression. Eligibility criteria include confirmed diagnosis of SMM for ≤5 years, factors indicating high risk of progression to MM (clonal bone marrow plasma cells [BMPCs] ≥10% and ≥1 of the following: serum M protein ≥30 g/L, IgA SMM, immunoparesis with reduction of 2 uninvolved Ig isotypes, serum involved:uninvolved free light chain ratio ≥8 to < 100, or clonal BMPCs > 50% to < 60% with measurable disease), and ECOG performance status ≤1. The primary endpoint is progression-free survival (PFS), assessed by an independent review committee, with disease progression defined according to International Myeloma Working Group diagnostic criteria for MM. Secondary endpoints include time to biochemical or diagnostic (SLiM-CRAB) progression, overall response rate, complete response rate, duration of response, time to response, time to first-line treatment for MM, PFS on first-line treatment for MM (PFS2), overall survival, and incidence of MM with adverse prognostic features. The study completed enrollment on May 6, 2019; 390 pts have been randomly assigned to DARA SC or active monitoring. The primary efficacy analysis will be performed after approximately 165 PFS events have been observed. Clinical trial information: NCT03301220.

Background: Light chain (AL) amyloidosis is a progressive and typically fatal disorder caused by misfolded AL protein produced by plasma cells. Birtamimab is a monoclonal antibody designed to neutralize circulating soluble and deposited insoluble amyloid, thus promoting phagocytic clearance. In 2018, the phase 3 VITAL study in newly diagnosed, treatment-naive patients was terminated based on futility analysis of the primary endpoint (time to all-cause mortality [ACM] or time to cardiac hospitalization > 90 days after first study drug infusion); the final hazard ratio (HR) numerically favored birtamimab + standard of care (SOC) over placebo + SOC (0.835 [95% CI: 0.5799, 1.2011]; p = 0.330). Post-hoc analysis of ACM over 9 months revealed a substantial survival benefit (HR = 0.413 [95% CI: 0.191, 0.895]; p = 0.025) in patients at high risk for early death (Mayo Stage IV). Post-hoc analyses of secondary endpoints in this subgroup indicated meaningful improvements in health-related quality of life (assessed with 36-Item Short Form Health Survey version 2; SF-36v2) and 6-minute walk test (6MWT) distance with birtamimab + SOC (p < 0.05) at 9 months. Methods: The phase 3, double-blind, placebo-controlled AFFIRM-AL study (NCT04973137) will enroll up to 150 Mayo Stage IV patients with newly diagnosed, untreated AL amyloidosis. Patients will be randomized (2:1) to 24 mg/kg intravenous birtamimab or placebo every 28 days. Both arms will receive concomitant chemotherapy with a first-line bortezomib-containing regimen, with or without daratumumab (D), at the discretion of the investigator. Patients will be stratified at randomization based on their 6MWT distance ( < 300 vs ≥300 meters) and initiation of D. The primary efficacy endpoint is time to ACM. Secondary endpoints are change from baseline to month 9 in the physical component summary of the SF-36v2 and 6MWT distance. This trial is powered at a significance level of 0.1 under a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration (FDA). Given the > 50% relative risk reduction for ACM observed in the post-hoc analysis of VITAL for patients with Mayo Stage IV disease, the AFFIRM-AL study is designed to confirm this effect of birtamimab. Approximately 130 global sites are planned; site initiation and patient randomization are underway. Conclusion: Treatments that improve survival in AL amyloidosis are needed, particularly for patients with advanced cardiac involvement, as median overall survival for those with Mayo Stage IV disease is ̃6–9 months. The AFFIRM-AL study is designed to confirm the survival benefit observed in the VITAL study in patients with Mayo Stage IV AL amyloidosis. Clinical trial information: NCT04973137.

Background: Taletrectinib (AB-106/DS-6051b) is a next-generation, brain-penetrant, ROS1/ NTRK tyrosine kinase inhibitor (TKI) and has shown clinically meaningful effect and safety profile in ROS1+ Non-Small Cell Lung Cancer (NSCLC) patients in phase 1 studies (Fujiwara et al, Oncotarget 2018; 9(34): 23729-23737; Ou et al, JTO Clin Res Rep. 2020 Oct 21;2(1):100108). Taletrectinib has also demonstrated activity against ROS1 G2032R resistance mutation and CNS metastases in the ongoing phase 2 TRUST study (NCT04395677) in China. Also, taletrectinib has shown preliminary efficacy against NTRK positive solid tumors in an ongoing phase 2 study (NCT04617054). Methods: TRUST-II study (NCT04919811) is a phase 2, global, multicenter, open-label, single-arm multi-cohort study evaluating the efficacy and safety of taletrectinib for ROS1 fusion-positive advanced metastatic NSCLC and other solid tumors. Taletrectinib will be given at 600 mg once daily in 21-day cycle. The patients with ROS1 fusions detected by local tests are eligible to enroll with retrospective confirmation by a central laboratory. The study consists of four cohorts: cohort 1: systemic chemotherapy naïve or ≤ one prior line and ROS1 TKI naïve NSCLC (N = 53); cohort 2: previously treated with one ROS1 TKI (crizotinib or entrectinib) and with progression who are either chemotherapy naïve or ≤ one line of platinum and/or pemetrexed based therapy for NSCLC (N = 46); cohort 3: ≤ 2 prior ROS1 TKIs and with progression who are either chemotherapy naïve or ≤ 2 lines of platinum and/or pemetrexed based therapy for NSCLC (N = 10); and cohort 4: systemic chemotherapy naïve or ≤ 2 prior lines of chemotherapy, but ROS1-TKI naïve ROS1 positive solid tumor other than NSCLC (N = 10). The primary endpoint is objective response rate (ORR) (RECIST v1.1) by independent review committee (IRC) assessment for cohorts 1 and 2. Key secondary endpoints include IRC-assessed duration of response, IRC-assessed intra-cranial ORR, progression free survival (PFS), overall survival (OS), and safety. This study is currently recruiting in Japan, Republic of Korea, and USA. Additional accrual is planned in Canada, China, and European Union. Clinical trial information: NCT04919811.

Background: Currently, EGFR-TKIs are widely accepted as the standard treatment for EGFR-mutant advanced NSCLC; however, acquired resistance is inevitable. Preclinical and clinical evidence has demonstrated that dual blockade of the EGFR and VEGF pathways is a viable strategy in the EGFR-mutant advanced NSCLC population to overcome the resistance to EGFR-TKIs. Aumolertinib (HS-10296) is a novel, third-generation EGFR-TKI approved in China to treat EGFR mutation positive non-small cell lung cancer. Apatinib is a small-molecule tyrosine kinase inhibitor that has promising anti-angiogenesis and antitumor activity for NSCLC. Here, we aimed to evaluate the safety and anticancer activity of aumolertinib alone/with apatinib for advanced/metastatic NSCLC patients with EGFR mutation. Methods: The phase III, multicenter, randomized, open-label, controlled study is evaluating the efficacy and safety of aumolertinib plus apatinib versus aumolertinib alone as first line therapy in adult patients with EGFR+ NSCLC. Adult patients with histologically confirmed stage IIIB/IV NSCLC harboring EGFR mutations without prior EGFR TKI treatment are eligible for this study. The performance status (Eastern Cooperative Oncology Group) is 0 or 1. This trial prepared to enroll approximately 300 patients, which will be randomized (1:1) to receive oral aumolertinib once daily 110 mg or adding apatinib 250 mg a day until assessed progressive disease(PD)，stratified by EGFR mutation (Ex19del /L858R/others) and distant metastases sites (brain/liver/others). The primary endpoint is progression free survival assessed by investigators using Response Evaluation Criteria in Solid Tumors 1.1. Secondary endpoints are disease control rate, duration of response, overall survival and safety. Adverse effects were graded per CTCAE v.4.03. This trial is registered as ChiCTR2100047453. Results: Recruiting. Conclusions: Recruiting. Clinical trial information: ChiCTR2100047453.

Background: RP1 is an oncolytic virus (HSV-1) that expresses a fusogenic glycoprotein (GALV-GP R-) and granulocyte macrophage colony stimulating factor (GM-CSF). In preclinical studies, RP1 induced immunogenic tumor cell death and provided potent systemic anti-tumor activity, which is further improved by combining anti-PD-1 therapy. The prognosis for advanced and metastatic cutaneous squamous cell carcinoma (CSCC) remains poor for many patients despite the adoption of cemiplimab and pembrolizumab as a standard treatment. Preliminary results from IGNYTE, a phase I/II clinical study of RP1 in combination with nivolumab showed a high rate of deep and durable responses in patients (pts) with CSCC. This study is evaluating the efficacy and safety of cemiplimab ± RP1 versus cemiplimab alone in advanced CSCC. Methods: This global, multicenter, randomized phase 2 study is enrolling pts with metastatic or unresectable, locally advanced CSCC who are not candidates for/refuse surgery and/or radiation therapy. Key eligibility criteria include no prior treatment with anti-PD1/PD-L1 antibodies or oncolytic viruses. The clinical trial is enrolling approximately 180 pts from centers in the EU, Australia, Canada, and USA. Pts are randomized in a 2:1 ratio to receive combination therapy or monotherapy respectively. Pts receive 350 mg of cemiplimab intravenously (IV) Q3W for up to 108 weeks. In the RP1 + cemiplimab arm, RP1 is injected intratumorally at a starting RP1 dose of 1 × 106 plaque-forming units (PFU)/mL alone, followed by up to 7 doses of RP1 at 1 × 107 PFU/mL Q3W together with the same dose of cemiplimab. Pts in the combination arm may receive up to 8 additional RP1 doses if protocol specific criteria are met. No crossover is allowed. Pts are stratified by disease status (nodal or distant metastatic or locally advanced CSCC) and prior systemic therapy. Tumor assessments are performed every 9 weeks. The dual independent primary endpoints are overall response rate and complete response rate, both by a blinded independent review. Secondary endpoints include safety, progression-free survival, duration of response, and overall survival. Exploratory endpoints include quality of life, and immune biomarker analyses. This trial is currently enrolling pts. Clinical trial information: NCT04050436.

Background: Uveal melanoma is a rare cancer. Up to 50% of patients (pts) develop metastasis, mainly hepatic. Overall survival in metastatic pts is 12 months (mo), contrasting with a good overall condition until death. To evaluate the impact of integrating early palliative care on patient needs and self-efficacy, we designed a comparative randomized trial in MUM pts. Methods: 162 pts will be randomized (1:2) between the control and the experimental groups in two French centres (Institut Curie-Paris and Centre Antoine Lacassagne-Nice). In the control group, palliative care is introduced according to international guidelines. In the experimental group, it is added earlier, concomitant to the announcement of metastases by the medical oncologist. The main objective is to assess if early supportive care impacts on patient psychological needs at 6 mo, versus standard of care, based on the SCNS-SF34 questionnaire. Secondary objectives include patient’s other needs at 6 and 12 mo, quality of life (QLQ-C30), progression-free and overall survival, and partners’ needs (SCNS-P&C). MUM pts, suitable for a treatment with no curative intent, ECOG PS 0-1, with no physical or biological sign of disease, and capable of filling questionnaires are eligible. Questionnaires are completed by all pts at each oncological visit (baseline, 3, 6, 9 and 12 mo). Supportive care visits take place every 6 weeks if needed and address patient’s information needs, disease and treatment understanding, social and psychological status, symptoms, and partners’ involvement. Prognostic uncertainty and disease seriousness in the absence of symptom is addressed depending on pts’ expressed needs. Medical oncologists and supportive care physicians from both centres attend communication skill training provided by an expert during the study. Analyses: SCNS-SF34 psychological needs scale scores at 6-mo will be compared with a Student’s t-test, in an ITT analysis. For 10 points mean score difference expected between groups (within standard deviation of 20 points) and a two-sided type 1 error of 5%, inclusion of 54 pts (control group) and 108 pts (experimental group) provides the study 85% of power. The planned inclusion period is 3 years, pts will be followed for one year, for a total study duration of 4 years. From July 2020 to January 2022, 63 pts have been enrolled in the trial; 2 pts declined. Five pts were removed early from the study: one for consent retrieval, 4 for early death due to metastasis. COVID-19 delayed enrollment for 5 months. We plan to complete the study Q4 2023 and to analyze the data Q4 2024. Clinical trial information: NCT04728113. [Table: see text]

Background: Immune checkpoint inhibitors (ICIs) are approved for multiple malignancies, however, durable remission rates with ICI monotherapy remains low. Combined treatment with anti-CTLA-4 and anti-PD1 has shown higher response rates in several cancers but is associated with up to 60% grade 3/4 immune-related adverse events (irAEs) leading to frequent treatment discontinuation. The need for corticosteroids to control irAEs may further diminish anti-tumor activity. A multi-disciplinary approach using clinical, preclinical, and translational analyses implicated the IL-6/Th17 axis in both ICI-related autoimmunity and resistance. Further, preliminary data showed that targeting interleukin 6 (IL-6) could be an effective approach to reduce irAEs while maintaining and possibly boosting the antitumor immune response. Methods: We are conducting a phase II, open-label, single center study to evaluate the use of combination treatment with tocilizumab (toci; anti-IL6), ipilimumab (ipi; anti-CTLA4) and nivolumab (nivo; anti-PD1) as a front-line therapy for patients (pts) with treatment-naïve advanced cutaneous melanoma (cohort 1), urothelial carcinoma (cohort 2), and EGFR mutant non-small cell lung cancer after tyrosine kinase inhibitors failure (cohort 3) (NCT04940299). Ten pts per disease site will be enrolled, plus an additional 25 melanoma pts in an expansion cohort. Key inclusion criteria are age ≥18 years (yrs) and histologically confirmed locally advanced or metastatic disease, with specific eligibility criteria defined for each cohort. Patients with interstitial lung diseases, autoimmune diseases, infection, or conditions requiring immunosuppressive therapies are not eligible, but stable asymptomatic brain mets are allowed. Ipi/Nivo dosing is as per approved disease indications: in cohort 1 &2, ipi 3 mg/kg + nivo 1 mg/kg is administered intravenously (IV) every 3 weeks (wks) for 4 doses then nivo 480 mg/4 wks up to 2 yrs. In cohort 3, IV ipi 1 mg/kg/6 wks + nivo 3 mg/kg/2 wks is administered up to 2 yrs. In all 3 cohorts, subcutaneous (SQ) toci 162 mg/2wks is administered up to 12 wks. Imaging is every 12 wks up to 2 yrs or until dose-limiting toxicities or progression. The primary outcome is safety/tolerability of the triple therapy. The secondary outcomes are antitumor efficacy and overall survival. Additionally, tumor and blood samples are being collected for longitudinal immune analysis, including gene expression and multiplex histochemistry to identify predictive biomarkers of response, resistance, and toxicity. The trial opened in October 2021 and has enrolled 14 patients to date. Clinical trial information: NCT04940299.
