- Incidence and severity of dose limiting toxicities (DLTs) during the DLT evaluation period of single-agent KFA115 (dose escalation only) [ Time Frame: 28 days ]A DLT is defined as an adverse event or abnormal laboratory value that occurs during the DLT evaluation period where the relationship to study treatment cannot be ruled out, and is not primarily related to disease, disease progression, intercurrent illness, or concomitant medications and meets the criteria defined in the study protocol

- Duration of response (DOR) per RECIST v1.1 [ Time Frame: 35 months ]DOR is defined as the time from the date of the first documented response (CR or PR) to the date of the first documented progression as per RECIST v1.1 or death due to underlying cancer

- Area under the concentration time curve (AUC) of KFA115 or tislelizumab [ Time Frame: During the first 168 days of treatment for single-agent KFA115 and 35 months for KFA115 in combination with tislelizumab ]Area under the concentration time curve
- Peak plasma or serum concentration (Cmax) of KFA115 or tislelizumab [ Time Frame: During the first 168 days of treatment for single-agent KFA115 and 35 months for KFA115 in combination with tislelizumab ]The maximum (peak) observed plasma or serum drug concentration after single dose administration
- Minimum plasma or serum concentration (Cmin) of KFA115 or tislelizumab [ Time Frame: During the first 168 days of treatment for single-agent KFA115 and 35 months for KFA115 in combination with tislelizumab ]The minimum observed plasma or serum drug concentration reached during the time interval between two dose administrations
- Time to reach peak plasma or serum concentration (Tmax) of KFA115 or tislelizumab [ Time Frame: During the first 168 days of treatment for single-agent KFA115 and 35 months for KFA115 in combination with tislelizumab ]The time to reach maximum (peak) plasma or serum drug concentration after single dose administration
- Elimination half-life (T1/2) of KFA115 or tislelizumab [ Time Frame: During the first 168 days of treatment for single-agent KFA115 and 35 months for KFA115 in combination with tislelizumab ]The elimination half-life associated with the terminal slope of a semi logarithmic concentration-time curve
- The number of participants with anti-drug antibodies (ADA) [ Time Frame: 35 months for KFA115 in combination with tislelizumab ]Immunogenicity of tislelizumab when dosed in combination with KFA115

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Non-small cell lung cancer with historic PD-L1 ≥ 1%, as determined locally using a clinically accepted assay. Patients must have experienced benefit from previous anti-PD(L)1-containing therapy for at least 4 months based on investigator-assessed disease stability or response prior to developing documented disease progression.
- Renal cell carcinoma, clear cell histology, previously treated with anti-PD(L)1-containing therapy and a VEGF targeted therapy as monotherapy or in combination. Patients should have documented disease progression following anti-PD(L)1-containing therapy.
- Cutaneous melanoma, previously treated with anti-PD(L)1-containing therapy. Patients should have documented disease progression following anti-PD(L)1-containing therapy.
- Ovarian cancer, high-grade serous histology, naive to anti-PD(L)1 therapy, no more than 3 prior lines of systemic therapy for recurrent/metastatic disease.
- Nasopharyngeal carcinoma, non-keratinizing locally advanced recurrent or metastatic, naive to anti-PD(L)1 therapy.
- Locally advanced unresectable or metastatic anal cancer (squamous), thymic carcinoma, MSI-H CRC, esophagogastric cancer, mesothelioma, and HNSCC, all naive to anti-PD(L)1 therapy.
- Patients must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy according to the treating institution's guidelines. Patient must be willing to undergo a new tumor biopsy at screening, and during therapy on the study, if medically feasible. Exceptions may be considered after documented discussion with Novartis. Patients with archival tumor tissue obtained ≤ 6 months prior to study treatment initiation do not need to undergo a new tumor biopsy at screening, if the patient has not received any anti-cancer therapy since the biopsy was taken, and if adequate tissue is available.
- Patients must have body weight > 36 kg.
Exclusion Criteria:
- Impaired cardiac function or clinically significant cardiac disease.
- Use of agents known to prolong the QT interval unless they can be permanently discontinued for the duration of study.
- History of severe hypersensitivity reactions to any ingredient of study drug(s) and other mAbs and/or their excipients.
- Active, known or suspected autoimmune disease. Patients with vitiligo, type I diabetes, residual hypothyroidism only requiring hormone replacement, psoriasis not requiring systemic treatment or conditions not expected to recur may be considered. Patients previously exposed to anti-PD-1/PD-L1 treatment who are adequately treated for skin rash or with replacement therapy for endocrinopathies should not be excluded.
- Any evidence of interstitial lung disease (ILD) or pneumonitis, or a prior history of ILD or non-infectious pneumonitis requiring high-dose glucocorticoids.
- Patients who discontinued prior anti-PD-(L)1 therapy due to an anti-PD-(L)1-related toxicity (applicable to the KFA115 in combination with tislelizumab treatment arms).
- Patients with symptomatic peripheral neuropathy limiting instrumental activities of daily living.
