Criteria

Inclusion Criteria:

1. Age 18 years and older

2. Subjects with any cancer receiving Cetuximab or Panitumumab on a weekly or every 2 weeks basis.

3. Scheduled to start Cetuximab or Panitumumab treatment;

4. Males or non-pregnant, non-lactating females who are postmenopausal, naturally or surgically sterile, or with a negative subunit hCG pregnancy test immediately prior to study entry.

5. Able to understand and provide signed informed consent.

6. Ability to reliably apply topical FDX104 and vehicle twice a day to the appropriate part of the face

7. Willingness to minimize sun exposure for 5 weeks from randomization

8. ECOG performance status 0-2.

Exclusion Criteria:

1. Prior allergic reaction or severe intolerance to Doxcycycline and/or other tetracyclines.

2. Prior allergic reaction or severe intolerance to soy or coconut oil

3. Cutaneous metastases on the face or might spread to the face.

4. The presence of any active skin disease (e.g., eczema), tattoos or other problems at application site, (i.e., located on the face) that, in the investigator's opinion, could confound the evaluation of the rash or make topical application unacceptable

5. Hair on the face (e.g beard) which would interfere with the application of the study drug or its evaluation.

6. ANC <1,500/mm3 (or<1.5x109/L), or Platelet count < 100,000/mm3 (or <100x109/L)

7. Abnormal renal functions: Serum creatinine >1.6 mg/dL or 142umol/L (SI units) or calculated estimated creatinine clearance <40 ml/min1.73 m2 based on Cockcroft and Gault formula.

8. Abnormal hepatic functions: Serum Aspartate transaminase (AST) or alanine tansaminase (ALT) >5 institutional upper limit of normal (ULN). Or Total billirubin > 2 x institutional ULN or >5 x institutional ULN if documented liver metastasis.

9. Any clinically significant safety laboratory results that, in the opinion of the Investigator, would place the subject at undue risk if the subject were to participate in the study

10. Any clinically significant finding on the physical examination that, in the opinion of the Investigator, would place the subject at undue risk if the subject were to participate in the study

11. Systemic lupus erythematosus

12. Undergoing any current biological treatment for cancer other than the prescribed EGFRI

13. Treatment with topical antibiotics, anti-acne medication and other topical treatments on the face within 14 days prior to treatment start. Use of topical corticosteroids within 2 weeks prior to baseline; only mild to moderate topical steroids are allowed outside the head and neck area. The area should not exceed 10% of the whole body surface area. In body folds, such as axillary and inguinal regions, only mild topical steroids are allowed in short term use (≤15 consecutive days).

14. Treatment with systemic antibiotics 7 days prior to treatment start.

15. Known or suspected pregnancy, or lactation or planned pregnancy (females)

16. Previous enrolment in a clinical trial involving investigational drug or a medical device within 30 days before provision of written informed consent for the study

17. Subjects who are mentally or physically unable to comply with all aspects of the study.
