Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - GSK3901961
Treatment: Drugs - Cyclophosphamide
Treatment: Drugs - Fludarabine

Experimental: GSK3901961 - Eligible participants will be leukapheresed to manufacture engineered T-cells. Participants will then receive high dose of GSK3901961 after completing lymphodepleting chemotherapy. The first study participant receiving GSK3901961 will receive the total assigned dose as 2 separate infusions 7 days apart, in aliquots of 30% (first infusion) and 70% (second infusion) of the total target dose, respectively. Based on the dose limiting toxicities reported in the first participant, then all subsequent participants treated with GSK3901961 will receive the full dose as a single, i.e., one-time, infusion.


Treatment: Drugs: GSK3901961
GSK3901961 was administered.

Treatment: Drugs: Cyclophosphamide
Cyclophosphamide was administered as lymphodepleting chemotherapy.

Treatment: Drugs: Fludarabine
Fludarabine was administered as lymphodepleting chemotherapy.

Outcomes
Primary outcome [1] 0 0
Number of Participants With Dose Limiting Toxicities (DLTs)
Assessment method [1] 0 0
DLT events were graded according to NCI-CTCAE v5.0. DLTs were defined as Grade (Gr) 4 (life-threatening and death) related to GSK3901961 2) Gr 3 (Severe or medically significant) at least possibly related to GSK3901961 and do not resolve to Gr \<=1 (or Baseline) within 7 days from the onset of the event 3) Gr \>=3 non-infectious pneumonitis not responding to oxygen supplementation and systemic steroid treatment 4) Any Gr 3 cytokine release syndrome (CRS) at least possibly related to GSK3901961 that does not improve to Gr \<2 (moderate) toxicity within 7 days with or without dexamethasone 5) Any Gr 4 CRS at least possibly related to study product that does not improve to Gr \<=2 (or Baseline) within 7 days 6) Any Gr 3 or greater neurotoxicity that does not resolve to Gr \<=2 within 72 hours 7) Any Gr \>=3 organ toxicity (exclusive of CRS toxicity) involving major organ systems that persists for \>72 hours and occurs within 28 days of infusion.
Timepoint [1] 0 0
Up to 28 days
Primary outcome [2] 0 0
Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious AEs Based on Maximum Severity
Assessment method [2] 0 0
An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. SAE is defined as any untoward medical occurrence that, at any dose can result in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth or is medically significant or requires intervention to prevent one or the outcomes listed above. AEs and SAEs were graded according to NCI-CTCAE v5.0. Grade 1- Mild; Grade 2- Moderate; Grade 3- Severe or medically significant but not immediately life-threatening; Grade 4- Life-threatening consequences; Grade 5- Death related to AE. AEs which start or worsen on or after T-cell infusion are classified as treatment emergent. SAEs are subset of AEs. Results for maximum severity grades has been presented.
Timepoint [2] 0 0
Up to approximately 21 months
Primary outcome [3] 0 0
Number of Participants With Treatment Emergent Adverse Events of Special Interest (AESI)
Assessment method [3] 0 0
An AESI may be of scientific and medical concern related to the treatment, monitored, and rapidly communicated by investigator to sponsor. AESIs included events of Cytokine Release Syndrome (CRS), Haematopoietic cytopenias (including pancytopenia and aplastic anaemia), Graft versus Host Disease (GvHD), Immune Effector-Cell Associated Neurotoxicity Syndrome (ICANS), Guillain-Barre Syndrome (GBS), Pneumonitis and treatment-related inflammatory response at tumor site(s) and Neutropenia Grade 4 lasting more than or equal to 28 days. AEs which start or worsen on or after T-cell infusion are classified as treatment emergent.
Timepoint [3] 0 0
Up to approximately 21 months
Secondary outcome [1] 0 0
Overall Response Rate (ORR) Assessed by Investigator According to RECIST v1.1
Assessment method [1] 0 0
Overall response rate (ORR) defined as the percentage of participants with a confirmed complete response (CR) or confirmed partial response (PR) via investigator assessment per Response Evaluation Criteria in Solid Tumors Criteria (RECIST) version 1.1 relative to the total number of participants in the analysis population. Partial response (PR) was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Complete response (CR) was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<)10 millimeters (mm). Confidence intervals (CI) were calculated using the exact (Clopper-Pearson) method.
Timepoint [1] 0 0
Up to approximately 21 months
Secondary outcome [2] 0 0
Duration of Response (DoR)
Assessment method [2] 0 0
DoR is defined as the interval of time (in months) from first documented evidence of the confirmed response (PR or CR) as assessed by local investigators to the date of disease progression per RECIST v1.1 or death due to any cause, among participants with a confirmed response of PR or CR. PR was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm.
