Inclusion Criteria
  • Radiographically, histologically, or cytologically confirmed advanced or refractory solid tumor(s) that is metastatic or unresectable, and previously received or was ineligible for standard treatment options. Participants with solid tumor(s) for which anti-PD-1 or anti-PD-L1 antibody as a monotherapy is approved in Japan are eligible.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
  • Thyroid function laboratory values within normal range
  • A woman must be: a) Not of childbearing potential; b) Of childbearing potential and practicing a highly effective, preferably user-independent method of contraception (failure rate of less than (<) 1 percent (%) per year when used consistently and correctly) and agrees to remain on a highly effective method while receiving study intervention and continue for 5 months following discontinuation of JNJ-63723283 or 3 months following discontinuation of erdafitinib, whichever is longer. Especially participants receiving erdafitinib must agree to use two contraceptive methods and one must be user-independent method; Examples of highly effective contraceptives include: user-independent methods: intrauterine device (IUD) or intrauterine contraceptive system (IUS) and user-dependent methods: combined (estrogen- and progestogen-containing) hormonal contraception or progesterone-containing hormonal contraception. c) Agree not to donate eggs (ova, oocytes), during the study and continue for 5 months following discontinuation of JNJ-63723283 or 3 months following discontinuation of erdafitinib, whichever is longer
  • A male participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person and must agree not to donate sperm for 5 months following discontinuation of JNJ-63723283 or 5 months following discontinuation of erdafitinib, whichever is longer
Exclusion Criteria
  • Had prior treatment with an anti-PD-1 antibody, anti-PD-L1 antibody or anti-PDL2 antibody within 30 days of first study drug administration and/or has an ongoing Grade 2 or higher immunotherapy-related toxicity. If the subject has an experience of treatment with these agents, the subject must not have had severe immunotherapy-related toxicity
  • History of or concurrent interstitial lung disease
  • Active autoimmune disease or a documented history of autoimmune disease that requires systemic steroids or immunosuppressive agents
  • Grade 3 or higher toxicity effects from previous treatment with immunotherapy
  • Has taken immunosuppressive doses of systemic medications, such as corticosteroids doses greater than (>) 10 milligram per day (mg/day) prednisolone or equivalent), within 2 weeks before the planned first dose of study drug

Phase 1b: Erdafitinib CombinationErdafitinibParticipants will receive erdafitinib in combination with JNJ-63723283 which will be escalated using BLRM.
Phase 1a: JNJ-63723283 (Monotherapy)JNJ-63723283Participants will receive monotherapy of JNJ-63723283 intravenously. The subsequent dose levels of JNJ-63723283 will be escalated using Bayesian logistic regression model (BLRM).
Phase 1b: Erdafitinib CombinationJNJ-63723283Participants will receive erdafitinib in combination with JNJ-63723283 which will be escalated using BLRM.
Primary Outcome Measures
NameTimeMethod
Phase 1a and Phase 1b: Number of Participants with Dose Limiting Toxicity (DLT)Up to 6 weeks (maximum)

The DLTs are based on drug-related adverse events and defined as any of the following events: Infusion-related reactions, non-hematologic toxicity of Grade 3 or higher, or certain hematologic toxicity.

Phase 1a and Phase 1b: Severity of DLT as Assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE)Up to 6 weeks (maximum)

Severity of DLT will be graded by using NCI-CTCAE, version 4.03. Severity scale ranges from Grade 1 to Grade 5 with Grades as follows: Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Life-threatening), and Grade 5 (Death).

Secondary Outcome Measures
NameTimeMethod
Phase 1b: Number of Participants with Adverse Events and Immune-Related Adverse Event (irAE) by SeverityApproximately up to 3 years

An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. Severity of Adverse Event will be graded by using NCI-CTCAE, version 4.03. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death) with Grades as follows: Grade 1 (Mild) Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Life threatening) and Grade 5 (Death).

Phase 1a and Phase 1b: Number of Participants With Clinically Significant Changes in Vital Signs as a Measure of Safety and TolerabilityApproximately up to 3 years

Number of participants with clinically significant changes in the vital signs including blood pressure, pulse rate, and body temperature will be reported.

Phase 1a and Phase 1b: Number of Participants With Clinical Laboratory Abnormalities as a Measure of Safety and TolerabilityApproximately up to 3 years

Number of participants with clinical laboratory abnormalities (clinical laboratory tests include the following: hematology panel, coagulation panel, serum chemistry panel, endocrine panel, serology and pregnancy test \[women only\]) will be reported.

Phase 1a and Phase 1b: Number of Participants With ECG Abnormalities as a Measure of Safety and TolerabilityApproximately up to 3 years

Number of participants with electrocardiogram (ECG) abnormalities will be reported.

Phase 1a and Phase 1b: Maximum Serum Concentration (Cmax) of JNJ-63723283Approximately up to 3 years

The Cmax is the maximum observed serum concentration.

Phase 1a and Phase 1b: Serum Concentration Immediately Prior to the Next Drug Administration (Ctrough) of JNJ-63723283Approximately up to 3 years

Ctrough is the serum concentration immediately prior to the next drug administration of any dose other than the first dose in a multiple dosing regimen.

Phase 1a and Phase 1b: Time to reach Maximum Observed serum Concentration (Tmax) of JNJ-63723283Approximately up to 3 years

The Tmax is defined as actual sampling time to reach maximum observed serum concentration.

Phase 1a and Phase 1b: Area Under the Serum Concentration-Time Curve Between 2 Defined Sampling Points, (t1 and t2) (AUC[t1-t2]) of JNJ-63723283Approximately up to 3 years

The AUC(t1-t2) is the area under the serum concentration-time curve between 2 defined sampling points, t1 and t2.

Phase 1a and Phase 1b: Elimination Half-Life (t1/2) of JNJ-63723283Approximately up to 3 years

T1/2 is the time measured for the serum concentration to decrease by 1 half to its original concentration.

Phase 1a and Phase 1b: Total Systemic Clearance (CL) of JNJ-63723283Approximately up to 3 years

CL is a quantitative measure of the rate at which JNJ-63723283 is removed from the body.

Phase 1a and Phase 1b: Volume of Distribution at Steady-State (Vss) of JNJ-63723283Approximately up to 3 years

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Steady state volume of distribution is the apparent volume of distribution at steady-state.

Phase 1b: Cmax of ErdafitinibApproximately up to 3 years

The Cmax is the maximum observed plasma concentration.

Phase 1b: Ctrough of ErdafitinibApproximately up to 3 years

Ctrough is the plasma concentration immediately prior to the next drug administration of any dose other than the first dose in a multiple dosing regimen.

Phase 1a and Phase 1b: Number of Participants With Anti-JNJ 63723283 AntibodiesApproximately up to 3 years
