MedImmune, LLC

The main purpose of this study is to determine the best dose of MEDI6469 that is safe and tolerable when given as monotherapy and in combination with tremelimumab, MEDI4736 (durvalumab), or rituximab in participants with either advanced solid tumors or diffuse large B-cell lymphoma (DLBCL). Tremelimumab and MEDI4736 (durvalumab) will be tested with MEDI6469 in a set of participants with advanced solid tumors while rituximab will be tested with MEDI6469 in participants with DLBCL. MEDI6469 will be tested as monotherapy in participants with advanced solid tumors.

A Phase 1b/2 Safety and Tolerability Study of MEDI6469 in Combination With Therapeutic Immune Agents or Monoclonal Antibodies

A Phase 1b/2, Open-label Study to Evaluate the Safety and Tolerability of MEDI6469 in Combination With Immune Therapeutic Agents or Therapeutic Monoclonal Antibodies in Subjects With Selected Advanced Solid Tumors or Aggressive B-cell Lymphomas

The MTD was the highest dose within a cohort where no more than 1 out of 6 participants experienced dose-limiting toxicities (DLTs) or the highest protocol-defined dose for each agent in the absence of exceeding the MTD.

The DLT was any Grade 3 or higher treatment-related toxicity (including liver transaminase elevation higher than 8×upper limit of normal \[ULN\] or total bilirubin higher than 5×ULN; any \>=Grade 2 pneumonitis that did not resolve to \<=Grade 1 within 3 days) that occurred during the DLT time frame, and excluded the following: Grade 3 fatigue for less than or equal to (\<=) 7 days; Grade 3 endocrinopathy that was managed and the participant was asymptomatic; Grade 3 inflammatory reaction attributed to a local antitumor response that resolved to \<=Grade 1 within 30 days; concurrent vitiligo or alopecia of any grade; Grade 3 infusion-related reaction that resolved within 6 hours; and any more than or equal to (\>=) Grade 3 lymphopenia (unless clinically significant).

An adverse event (AE) was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. TEAEs were events present at baseline that worsened in intensity after administration of study treatment or events absent at baseline that emerged after administration of study treatment.

A serious adverse event (SAE) was any AE that resulted in death, immediately life threatening, required (or prolonged) inpatient (or existing) hospitalization, resulted in persistent or significant disability/incapacity, congenital anomaly or birth defect in offspring of the participant, or an important medical event that could jeopardize the participant or required medical intervention to prevent one of the outcomes listed above. Treatment-emergent SAEs were defined as SAEs present at baseline that worsened in intensity after administration of study treatment or SAEs absent at baseline that emerged after administration of study treatment.

Laboratory evaluations of blood and urine samples were performed, including hematology (white blood cell \[WBC\] count with differential, red blood cell \[RBC\] count, hematocrit, hemoglobin, platelet count, mean corpuscular volume \[MCV\], and mean corpuscular hemoglobin concentration \[MCHC\]); serum chemistry (calcium, chloride, magnesium, creatinine, sodium, blood urea nitrogen \[BUN\], bicarbonate, glucose, aspartate transaminase \[AST\], total bilirubin, C-reactive protein, gamma-glutamyl transpeptidase \[GGT\], lactate dehydrogenase, uric acid, potassium, alanine transaminase \[ALT\], alkaline phosphatase, albumin, total protein, triglycerides, and cholesterol); urinalysis; and coagulation parameters.

Vital signs examination included assessment of temperature, blood pressure, pulse rate, and respiratory rate. Physical examination included assessments of head, eyes, ears, nose, throat, respiratory, cardiovascular, gastrointestinal, urogenital, musculoskeletal, neurological, psychiatric, dermatological, hematologic/lymphatic, and endocrine systems. The TEAEs related to these vital sign and physical examination abnormalities were reported.

Electrocardiogram (ECG) parameters included atrial rate, PR interval, QRS duration, QTC interval, QT interval, and ventricular rate. All 12-lead ECGs performed during the study were obtained in triplicate. The TEAEs related to these ECG evaluation abnormalities were reported.

Best overall response: Percentage (%) of participants with CR, partial response (PR), stable disease (SD), progressive disease (PD), or non-evaluable disease based on revised Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST v1.1) for monotherapy and combination tremelimumab and durvalumab arms, and Cheson criteria for combination rituximuab arms. Per RECIST v1.1: CR-disappearance of all target/non-target lesions; PR at least a 30% decrease in sum of diameters of target lesions; SD-neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD; PD-at least a 20% increase in sum of diameters of target lesions, or a substantial worsening in a non-target lesion, or the appearance of new lesions. Per Cheson criteria: CR-disappearance of all evidence of disease; PR-regression of measurable disease and no new sites; SD-failure to attain CR/PR or PD; PD-any new lesion or increase by at least 50% of previously involved sites from nadir.

Objective response rate was defined as the percentage of participants with confirmed CR or confirmed PR according to revised RECIST v1.1 for monotherapy and combination tremelimumab and durvalumab arms, and Cheson criteria for combination rituximuab arms. Confirmed CR and PR were those that persisted on repeat consecutive assessment \>= 4 weeks after the initial documentation of response. Tumor assessments according to revised RECIST v1.1 were defined as follows: CR - disappearance of all target/non-target lesions; PR - at least a 30% decrease in the sum of the diameters of target lesions. Tumor assessments according to Cheson criteria were defined as follows: CR - disappearance of all evidence of disease; PR- regression of measurable disease and no new sites.

Disease control rate: Percentage of participants with CR, PR, or SD (if they maintained SD for \>= 8 weeks) according to revised RECIST v1.1 for monotherapy and combination tremelimumab and durvalumab arms, and Cheson criteria for combination rituximuab arms. Tumor assessments according to revised RECIST v1.1 were defined as follows: CR -disappearance of all target/non-target lesions; PR - at least a 30% decrease in sum of diameters of target lesions; SD - neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD; PD - at least a 20% increase in sum of diameters of target lesions, or a substantial worsening in a non-target lesion, or the appearance of new lesions. Tumor assessments according to Cheson criteria were defined as follows: CR- disappearance of all evidence of disease; PR - regression of measurable disease and no new sites; SD- failure to attain CR/PR or PD; PD- any new lesion or increase by at least 50% of previously involved sites from nadir.

Duration of response was the duration from the first documented objective response to the first documented PD or death due to any cause, whichever occurred first. Progression was based on revised RECIST v1.1 criteria for monotherapy and combination tremelimumab and durvalumab arms, and Cheson criteria for combination rituximuab arms. PD according to revised RECIST v1.1 was defined as: at least a 20% increase in the sum of diameters of target lesions, or a substantial worsening in a non-target lesion, or the appearance of new lesions. PD per Cheson criteria was defined as: any new lesion or increase by at least 50% of previously involved sites from nadir.

Progression-free survival was the duration measured from the start of study treatment until the first documentation of PD or death due to any cause, whichever occurred first. Progression was based on revised RECIST v1.1 criteria for monotherapy and combination tremelimumab and durvalumab arms, and Cheson criteria for combination rituximuab arms. PD according to revised RECIST v1.1 was defined as: at least a 20% increase in the sum of diameters of target lesions, or a substantial worsening in a non-target lesion, or the appearance of new lesions. PD per Cheson criteria was defined as: any new lesion or increase by at least 50% of previously involved sites from nadir.

The OS was the duration from the start of study treatment until death due to any cause.

The pharmacokinetics (PK) parameter was estimated using the non-compartmental analysis methods, based on the participant serum concentration-time data. The concentration-time curve was the result of blood sampling at specified time points and its measured concentration of MEDI6469
