A Phase Ib Study to Evaluate the Safety, Tolerability, and Pharmacokinetics (PK) of Avelumab in Combination With M9241(NHS-IL12) (JAVELIN IL-12)

Stopped early · Phase 1

Conditions studied: Advanced Solid Tumors

In brief

The study consisted of 2 parts: Dose Escalation phase (Part A) and Expansion phase (Part B). The dose escalation phase evaluated the safety, tolerability, and PK of avelumab in combination with M9241 in subjects with locally advanced, unresectable, or metastatic solid tumors. Expansion phase assessed the safety and clinical activity of the combination regimen in selected tumor types. In Expansion phase subjects who had completed the combination treatment of avelumab at a given dose level of M9241, a safety review was performed by the Safety monitoring committee in order to make a decision on the next dose level. Successive cohorts of 3 to 6 subjects were treated with escalating doses of M9241 with avelumab intravenous (IV).

• subjects who had been treated previously with a checkpoint inhibitor may enroll (except as outlined below for expansion cohorts).
• at least 1 unidimensional radiographically measurable lesion based on response evaluation criteria in solid tumors (recist) version 1. 1 (v1. 1), except for subjects with metastatic castration-resistant prostate cancer (crpc) or metastatic breast cancer who may been enrolled with objective evidence of disease without a measureable lesion. - eastern cooperative oncology group (ecog) performance status of 0 to 1 at screening

• adequate renal function as defined by an estimated creatinine clearance >= 50 milliliter per minute (ml/min) according to cockcroft-gault formula
• negative blood pregnancy test at screening for women of childbearing potential. For purposes of this trial, women of childbearing potential were defined as all female subjects after puberty unless they were postmenopausal for at least 1 year, surgically sterile or sexually inactive.
• highly effective contraception (ie, methods with a failure rate of less than 1% per year) must been used before started of treatment, for duration of trial treatment, and for at least 50 days after stopping studied treatment for both men and women if risk of conception exists. The effects of avelumab and m9241 on developing human fetus were unknown; thus, women of childbearing potential and men agreed to use highly effective contraception.
• Part B:
• Availability of a fresh tumor biopsy was mandatory for eligibility in the RCC cohort. The biopsy or surgical specimen should be collected within 28 days prior to the first IMP administration. If a subject had 2 separate biopsy attempts in which usable tissue was not obtained, enrollment would have been possible after discussion with the Medical Monitor. For other expansion cohorts, availability of either tumor archival material (< 6 months old) or fresh biopsies (obtained within 28 days) was acceptable with one of these being mandatory. For formalin-fixed paraffin-embedded samples, either block or sections (> 15) provided. Tumor biopsies and tumor archival material should have been suitable for biomarker assessment - Locally advanced or metastatic UC that had progressed during or after at least one previous platinum-based chemotherapy and not previously treated with anti-PD-1/PD-L1 agents: Histologically or cytologically confirmed locally advanced or metastatic transitional cell carcinoma of urothelium(including renal pelvis, ureters, urinary bladder, and urethra). Participants must had progressed during or after treatment with at least 1 platinum-containing regimen for inoperable locally advanced or metastatic UC or disease recurrence. Participants who had received prior adjuvant/neoadjuvant chemotherapy and progressed within 12 months of treatment with a platinum-containing regimen were considered as second line. Participants with mixed histologies were required to have a dominant transitional cell pattern.
• Non-small cell lung cancer (NSCLC), first-line metastatic: Stage IV (per seventh International Association for the Study of Lung Cancer classification) histologically confirmed NSCLC. Participants must not had received treatment for their metastatic disease. Participants could have received adjuvant chemotherapy or loco-regional treatment that included chemotherapy for locally advanced disease, as long as disease recurrence occurred at least 6 months after the completion of the last administration of chemotherapy. Only epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) wild-type were allowed (ie, EGFR mutation and ALK translocation / re arrangement excluded). Non squamous cell histologies and never / former light smoker (< 15 pack years) squamous cell carcinoma Participants (per local standard of care) required testing if status was unknown. Participants must had low tumor PD-L1 expression defined as < 50% tumor proportion score determined using PD-L1 IHC 22C3 pharmDx test or an equivalent Food and Drug Administration (FDA)- approved PD-L1 test. Availability of either tumor archival material or fresh biopsies within 28 days was acceptable with one of these being mandatory. For FFPE samples, either block or sections (> 15) may be provided. Tumor biopsies and tumor archival material had been suitable for biomarker assessment. This cohort would not be opened for enrollment in Belgium, Czech Republic, France, Germany, Hungary, Italy, Netherlands, Spain, and United Kingdom.
• Colorectal cancer (CRC): Histologically or cytologically confirmed recurrent or refractory metastatic CRC (according to American Joint Committee on Cancer / International Union Against Cancer Tumor Node Metastasis [TNM] Staging System seventh edition) after failure of prior therapy containing oxaliplatin / fluoropyrimidine and / or irinotecan / fluoropyrimidine and, if eligible, cetuximab (Erbitux®) and bevacizumab (Avastin®). Only Participants with microsatellite instability (MSI)-low or microsatellite stable (MSS) metastatic CRC are eligible. Participants without existing MSI test results had MSI status performed locally by a Clinical Laboratory Improvement Amendments (CLIA)-certified IHC or polymerase chain reaction (PCR)-based test (PCR based MSI test is preferred). Participants had to be willing to undergo an on-treatment biopsy procedure. Availability of either tumor archival material or fresh biopsies within 28 days was acceptable with one of these being mandatory. For FFPE samples, either a block or sections (> 15) could be provided. Tumor biopsies and tumor archival material had to be suitable for biomarker assessment. For Belgium, Czech Republic, France, Germany, Hungary, Italy, Netherlands, Spain, and United Kingdom, participants in the second-line setting had exhausted or were considered ineligible or intolerant (in the opinion of the Investigator) of available second-line chemotherapy options.
