Brief Summary

This is a study in adult patients with different types of cancer. The purpose of this study is to find a safe dose of:

* Xentuzumab in combination with abemaciclib

* Xentuzumab in combination with abemaciclib and hormonal therapies The study also tests whether these medicines make tumours shrink in participants with lung and breast cancer.

Participants can stay in the study as long as they benefit from and can tolerate treatment. All participants get xentuzumab infusions and abemaciclib tablets. Participants who have breast cancer get different types of hormonal therapies in addition to xentuzumab and abemaciclib.

For all participants, the size of the tumour is measured regularly. Doctors also regularly check the general health of the participants."

[Cohort A, B, C & D] Number of Patients With DLTs in the MTD Evaluation PeriodThe first treatment cycle, up to 28 days.

Number of patients with Dose limiting toxicities in the MTD evaluation period.

Dose limiting toxicity (DLT): adverse event or laboratory abnormality which 1) is related, probably related or possibly related to study drug and 2) meets any of the following criteria, unless that toxicity can be attributed to cancer progression or to identified etiology:

CTCAE grade (Gr). 3+ hyperglycaemia (\>48 hours), Gr. 4 hyperglycaemia, hematologic toxicity (\>5 days), Gr. 3+ pneumonitis, febrile neutropenia, thrombocytopenia (Gr. 4 any duration, Gr. 3 w/ bleeding), AST/ALT \> 5x ULN or \> (baseline + 4x ULN), Gr. 3+ diarrhoea, nausea, vomiting (\>2 days), skin rash, fatigue/asthenia (\>7 days), Gr. 3-4 hyperlipidaemia (\>2 weeks), Any AE causing 2-week treatment interruption, non-hematologic toxicities Gr. 3+ (except alopecia, infusion-related reaction), Any significant drug related toxicity qualified as DLT.

[Cohort E] Number of Patients With Objective Response (OR)Up to 26.5 months

Objective response (OR) defined as best overall response of complete response (CR) or partial response (PR), where best overall response is determined according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1 from date of first treatment administration (including run-in for cohort E) until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anti-cancer therapy.

Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in short axis to \<10 millimeter (mm)). For non-target lesions: disappearance of all non-target lesions and normalization of tumour marker level. All lymph nodes must be non-pathological in size (\<10mm short axis).

Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameters.

[Cohorts D1 and D2] Progression Free Survival (PFS) at 18 MonthsUp to 18 months.

Progression free survival (PFS) rate at 18 month defined as the rate of absence of disease progression or death at the 18th month of treatment, where progression is determined according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1.

Progression (PD): At least a 20% increase in the sum of diameters of target lesions, taking as references the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. For non-target lesions: Unequivocal progression of existing non-target lesions (Note: the appearance of one or more new lesions is also considered progression).

Reported is the progression free survival rate at 18 months, based on a Kaplan-Meier.

[Cohort F] Disease Control (DC)Up to 18.5 months.

Disease control (DC) defined as best overall response of complete response (CR) or partial response (PR) or confirmed stable disease (SD) (lasting for at least 24 weeks) or Non-CR/ Non-PD (lasting for at least 24 weeks) where best overall response is defined according to RECIST version 1.1 from first treatment administration until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anti-cancer therapy.

Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as references the smallest sum diameters while on study.

Secondary Outcome Measures
NameTimeMethod
[Cohorts E, D1 and D2] Disease Control (DC)Up to 35.2 months.

Disease control (DC) defined as best overall response of complete response (CR) or partial response (PR) or confirmed stable disease (SD) (lasting for at least 24 weeks) or Non-CR/ Non-PD (lasting for at least 24 weeks) where best overall response is defined according to RECIST version 1.1 from first treatment administration until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anti-cancer therapy.

Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as references the smallest sum diameters while on study.

[Cohorts E, F, D1 and D2] Duration of Objective ResponseUp to 27.2 months.

Duration of objective response defined as the time from first documented complete response (CR) or partial response (PR) until the earliest of disease progression or death among patients with objective response.

[Cohorts E, F, D1 and D2] Progression-free Survival (PFS)Up to 33 months.

Progression-free survival (PFS) defined as the time from first treatment administration until tumour progression according to RECIST 1.1 or death from any cause, whichever occurs earlier.

Progression (PD): At least a 20% increase in the sum of diameters of target lesions, taking as references the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. For non-target lesions: Unequivocal progression of existing non-target lesions (Note: the appearance of one or more new lesions is also considered progression).

[Cohorts D1, D2 and F] Objective Response (OR)Up to 35.2 months.

Objective response (OR) defined as best overall response of complete response (CR) or partial response (PR), where best overall response is determined according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1 from date of first treatment administration until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anti-cancer therapy.

Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in short axis to \<10 millimeter (mm)). For non-target lesions: disappearance of all non-target lesions and normalization of tumour marker level. All lymph nodes must be non-pathological in size (\<10mm short axis).

Duration of disease control defined as the time from first treatment administration until the earliest of disease progression or death, among patients with disease control.
