- < 3 × ULN for persons with Gilbert's syndrome OR

- Direct bilirubin = ULN for patients with total bilirubin levels > 1.5 × ULN

- Aspartate transaminase (AST) and alanine transaminase (ALT) (also known as
serum glutamic oxaloacetic transaminase and serum glutamic pyruvic
transaminase)

- = 2.5 × ULN OR

- = 5 × ULN for patients with liver metastases

4. Coagulation:

- International normalized ratio or prothrombin time (PT) = 1.5 × ULN unless
patient is receiving anticoagulant therapy, and as long as PT or partial
thromboplastin time (PTT) is within therapeutic range of intended use of
anticoagulants

- Activated partial thromboplastin time (aPTT) = 1.5 × ULN unless patient is
receiving anticoagulant therapy, and as long as PT or PTT is within
therapeutic range of intended use of anticoagulants

5. Have provided 2 tissue biopsy samples taken of the target lesion (Lesion A) as a
single biopsy split into 2 samples or 2 separate biopsies that meet the minimal sample
size requirement per the study laboratory manual. One sample is for determining PD-L1
expression level by immunohistochemistry and can be an archival sample of the
anticipated target lesion that has been collected within 3 months of screening. The
other sample is for RNA expression profiling and must be a fresh biopsy.

6. Life expectancy of at least 6 months

7. Female patients of childbearing potential, as defined in Section 5.2.1, must have a
negative urine or serum pregnancy test within 72 hours prior to taking the first dose
of trial treatment. If the urine test is positive or cannot be confirmed as negative
then a serum test is required which must be negative for the patient to enroll. Women
of childbearing potential (WOCBP) must be willing to use 2 medically acceptable
methods of contraceptive from Day 1 through 120 days after the last dose of trial
treatment. The 2 medically acceptable birth control methods can be either 2 barrier
methods or a barrier method plus a hormonal method to prevent pregnancy. The following
are considered adequate barrier methods of contraception: diaphragm, condom (by the
partner), copper intrauterine device, sponge, or spermicide as per local regulations
or guidelines. Appropriate hormonal contraceptives will include any registered and
marketed contraceptive agent that contains an estrogen and/or a progestational agent
(including oral, subcutaneous, intrauterine, or intramuscular agents).

Male patients of reproductive potential, as described in Section 5.2.1, must agree to
use an adequate method of contraception from Day 1 through 120 days after the last
dose of trial treatment.

Abstinence is acceptable if this is the usual lifestyle and preferred contraception
for the patient.

8. Histologically or cytologically confirmed unresectable or metastatic (stage IV)
melanoma

9. For Phase 1 Escalation Cohorts 1-4, must have at least 1 lesion that qualifies as a
target lesion per RECIST v1.1 except for the minimum measurement of 10 mm in diameter
for superficial lesions, is easily accessible (palpable or can be visualized by

at least 4 weeks from the date of the first documented PD, in the absence of
rapid clinical progression

[Inclusion Criteria (Phase 2 only: HNSCC)]

14. Histologically or cytologically confirmed recurrent or metastatic HNSCC that could not
be treated with curative intent

15. Must have at least 1 lesion that qualifies as a target lesion per RECIST v1.1, and
which must be easily accessible (palpable or can be visualized by ultrasound) and
amenable to multiple intratumoral injections. The target lesion should be of
sufficient size such that the required tumor biopsies do not significantly affect
tumor assessment per RECIST v1.1. Tumor lesions situated in a previously irradiated
area, or in an area subjected to other loco-regional therapy, are usually not
considered measurable unless there has been demonstrated progression in the lesion.
Approval from the Medical Monitor is required to inject a previously radiated lesion.

treatment regimen containing an anti-PD-1/L1 drug (see Appendix 6 for definition of PD
per RECIST v1.1)

Summary
Brief summary
This is a phase 1b/2, open-label, multicenter trial designed to evaluate the safety,
tolerability, biologic activity, and preliminary efficacy of intratumoral SD-101 injections
in combination with intravenous pembrolizumab in patients with metastatic melanoma or
recurrent or metastatic head and neck squamous cell carcinoma (HNSCC).

This study will be conducted in 2 phases. Phase 1 evaluates SD-101 given in combination with
pembrolizumab in melanoma populations (anti-PD-1/L1 naïve and anti-PD-1/L1 experienced with
progressive disease) in up to 4 Dose Escalation cohorts to identify a recommended Phase 2
dose (RP2D) to be evaluated in up to 4 Dose Expansion cohorts in Phase 2. Phase 2 also
includes up to 4 Dose Expansion cohorts of patients with HNSCC (anti-PD-1/L1 naïve and
anti-PD-1/L1 experienced with progressive disease).
