Eligibility Criteria

Inclusion Criteria:

Patient is at least ≥18 years of age (male or female).

Disease characteristics for patients in Part 1:

a. Patient with any histologically or cytologically confirmed solid tumor that is locally advanced or metastatic or unresectable tumor and has disease progression after treatment with available therapies that are known to confer clinical benefit or who are intolerant to treatment.

Note: Tumor types of primary interest in Part 1 Dose Escalation include tumors which are relapsed or refractory after anti PD-1/PD-L1 therapy (include but not limited to malignant melanoma, HNSCC, renal cell carcinoma, hepatocellular carcinoma, Merkel cell carcinoma, urothelial, non-small cell lung cancer, gastric carcinoma, ovarian carcinoma, endometrial, TNBC, cervical cancer, and colorectal carcinoma)

Disease characteristics and prior treatments for patients in Part 2:

Cohort A (Melanoma): Patients with advanced or metastatic melanoma who have progressed following treatment with an anti-PD-1 or anti-PD-L1 antibody. Patients with BRAF mutated melanoma must have previously received BRAF/MEK targeted therapy.
Cohort B (Head and Neck): Patient has anti-PD-1/PD-L1 refractory metastatic or recurrent HNSCC of the oral cavity, oropharynx, hypopharynx, or larynx. Participants may not have a primary tumor site of the nasopharynx (any histology).

i. Has histologically confirmed Stage III, IVa, or IVb disease per TNM staging, American Joint Committee on Cancer (AJCC, 8th edition), with recurrent or persistent disease after definitive chemoradiation, deemed unresectable and considered refractory to both platinum-based combination chemotherapy and anti-PD-1/PD-L1 antibody therapy OR ii. Has histologically confirmed Stage IVc disease per TNM staging, AJCC 8th edition, considered refractory to platinum-based combination chemotherapy and anti-PD-1/PD-L1 antibody therapy.

c. Cohort C: Tumor types not in Cohort A and B - Naïve or relapsed refractory to anti PD-1/PD-L1

An Eastern Cooperative Oncology Group (ECOG) performance status ≤1
Estimated life expectancy ≥3 months
Measurable disease according to RECIST criteria v 1.1
Patients must have recovered (ie, to NCI CTCAE grade ≤1) from all toxicity associated with previous treatments (exception: patients may enter with continuing alopecia irrespective of CTCAE grade).
All women of childbearing potential must have a negative pregnancy test at Screening, prior to study drug administration
Women of childbearing potential include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal. Postmenopausal is defined as: (1) Amenorrhea ≥12 consecutive months without another cause and a documented serum follicle stimulating hormone (FSH) level >35 mIU/mL; (2) Women with irregular menstrual periods and a documented serum FSH level >35 mIU/mL; or (3) Women on hormone replacement therapy (HRT)

All patients, male and female, who are not surgically sterilized or postmenopausal as defined above, must agree to use dual effective birth control during the study and for at least 28 days after the last dose of study medication and 5 months after the last dose of atezolizumab.

Highly effective methods of contraception are hormonal contraceptives (oral, injectable, patch, intrauterine devices), male partner sterilization, or total abstinence from heterosexual intercourse, when this is the preferred and usual lifestyle of the patient. Note: The double-barrier method (eg, synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel), periodic abstinence (such as calendar, symptothermal, post-ovulation), withdrawal (coitus interruptus), lactational amenorrhea method, and spermicide only are not acceptable as highly effective methods of contraception

Patients has adequate hematologic and organ function, defined as:

ANC ≥1500 mm3 without requiring G-CSF
Platelets ≥100,000/mm3
Hemoglobin ≥9 g/dL Note: Patients with Hb 7 to ≤9 g/dL (without bleeding) transfused prior to dosing in order to meet eligibility criteria
Serum creatinine ≤1.5× upper limit of normal (ULN) for the reference laboratory or creatinine clearance ≥50 mL/min within the 28 days before enrollment (calculated from Cockcroft-Gault formula or 24 hour urine collection).
Alanine aminotransferase (ALT), aspartate transaminase (AST) ≤3.0× the upper limit of normal (ULN) if no liver involvement or ≤5×ULN with liver involvement
Adequate coagulation: prothrombin time (PT), an International Normalized Ratio (INR) or activated partial thromboplastin time (aPTT) ≤1.5×ULN or for patients requiring anticoagulant therapy, the PT/INR, aPTT should be within therapeutic range of the given anticoagulant agent
Total bilirubin ≤1.5×ULN (or total serum bilirubin ≤3×ULN for patients with Gilbert's disease)
Patients must be willing and able to provide written informed consent prior to the performance of any study-specific procedure

Exclusion Criteria:

Women who are pregnant or lactating or expecting to conceive a child within the projected duration of the study
History or evidence of cardiovascular (CV) risk including any of the following: Recent (within the past 6 months) history of serious uncontrolled cardiac arrhythmia or clinically significant ECG abnormalities including second degree (Type II) or third degree atrioventricular block; Cardiomyopathy, myocardial infarction, acute coronary syndromes (including unstable angina pectoris), coronary angioplasty, stenting, or bypass grafting within the past 6 months before enrolment; Congestive heart failure (Class II, III, or IV) as defined by the New York Heart Association functional classification system (NYHA).
Patients with marked Baseline QTc prolongation (QT interval corrected for rate by Fridericia's formula [QTcF] ≥470 msec for women and ≥450 msec for men on the ECG obtained at Screening by mean of three ECGs).
Use of concomitant medications known to moderately or severly prolong QT interval.
Patients with active or ongoing infection requiring systemic IV antibiotic therapy. Patients with active or ongoing Epstein-Barr virus, hepatitis B virus, or hepatitis C virus or with known human immunodeficiency virus (HIV) infection, tuberculosis, or other infections within 4 weeks.
Clinically significant pulmonary disease, chronic or recurrent renal or urinary tract disease, liver disease, endocrine disorder, autoimmune disorder, or neuromuscular, musculoskeletal, or mucocutaneous conditions that, in the opinion of the Investigator, put the patient at additional risk by participating in the study or otherwise make the patient unsuitable for the study
The patient has uncontrolled intercurrent illness including, but not limited to uncontrolled infection, including uncontrolled diabetes mellitus or decreased pulmonary function, or psychiatric illness/social situations that would limit compliance with study
Has an active autoimmune disease that has required systemic treatment in the past 2 years (ie, with use of disease modifying agents, corticosteroids, or immunosuppressive drugs) except vitiligo or resolved childhood asthma/atopy. Replacement therapy, such as thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, is not considered a form of systemic treatment
Patients with a history of or active pneumonitis Grade ≥ 2 (from any etiology).
Patients who have discontinued prior immunotherapy due to immune-related adverse reaction(s)

Note: The use of physiologic replacement doses of corticosteroids may be approved after consultation with the Sponsor's Medical Monitor or designee
Patients who have undergone major surgery within the last 4 weeks
Patients with new brain metastasis. Patients with treated (surgically excised or irradiated) and stable brain metastases are eligible as long as the treatment was at least 4 weeks prior to initiation of study drug and baseline brain CT with contrast or MRI within 2 weeks of initiation of study drug is negative for new brain metastases
Active malignant disease other than that being treated in this study. Exceptions: malignancies that were treated curatively and have not recurred within the past 2 years; completely resected basal cell carcinoma and squamous cell carcinoma of the skin; and completely resected carcinoma in situ of any type.

Patient- Prior treatment with the following agents:

Stimulator of Interferon Genes (STING) agonist at any time.
Anticancer therapy or investigational therapy within 28 days or 5 half-lives of the drug, whichever is shorter; "Check-point inhibitors", including Programmed death receptor-1 (PD-1), PD-L1 and Cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitors within 28 days (except part 2 Cohort C);
Prior radiation therapy: permissible if at least 1 non-irradiated measurable lesion is available for assessment according to RECIST version 1.1 or if a solitary measurable lesion was irradiated, objective progression is documented. A wash out of at least 28 days before start of study treatment for radiation of any intended use to the extremities for bone metastases and 28 days for radiation to the chest, brain, or visceral organs is required. Palliative radiation is permissible at any time before or during the study.
Receipt of any live vaccines within 4 weeks prior to the initiation of study drug and anticipation of need for such a vaccine during atezolizumab treatment or within 5 months after the final dose of atezolizumab.
Patients considered by Investigators for any other reason to be unsuitable for the study or unable to comply with all study procedures and follow-up examinations.
